Horseshoe hollow cup motor coil and winding machine

            In recent years, China has paid more and more attention to hollow cup motor and automatic winding technology, and has made good progress and breakthroughs in the research and development and manufacturing of winding machine equipment.

One of the key reasons for the impact on the performance of the motor is the rotor coil in the motor, the rotor in the hollow cup motor has no iron core, small inertia, excellent functionality and a wide range of applications. In addition, in the research and development of coil winding equipment, the saddle-shaped coil arrangement is regular, and the utilization efficiency of magnets is high.

           Compared with the old traditional motor with an iron core, the energy conversion efficiency is significantly higher than the latter, and the reaction speed will be much faster, and the hollow cup motor has high efficiency, fast response speed and stable performance. Because the hollow cup motor has no lag, additional electromagnetic interference is low, very high motor speed can be achieved, and the speed setting is sensitive at high speed, so it has relatively stable and stable performance. In addition, the energy density of the hollow cup motor is much greater than that of other motors, and the weight will be much less than that of an iron core motor with the same power.

           Now according to the forming method of the coil, in the hollow cup motor coil, its production technology can be roughly divided into two process routes: winding production technology and one molding production technology.

           Compared with the two methods, the first winding production technology is more complex, and the efficiency of winding the coil is relatively low. In order to improve the winding efficiency of coil production, the winding machine can be added to the production process of one molding. According to the hollow cup coil shape and winding method, the common hollow cup winding method can be divided into three kinds of parallel straight winding, saddle winding and oblique winding. The first parallel straight winding is generally used for hollow cup motor winding with relatively few turns. The last two are the two coil winding processes commonly used by the relatively advanced hollow cup motor manufacturers abroad.

Instructions for use of magnetic damping tensioner for winding machine

Instructions for use of standard winding machine tensioner

        This type of winding machine of Xiepu has a stroke of 1.5 meters, adopts pneumatic quick assembly and quick disassembly, convenient operation, mature and stable structure, easy maintenance, easy operation of the system, complete functions, and strong expandability.

        At present, according to customer requirements, a heating coil with a stroke of up to 1.5 meters is wound on this machine. Because the equipment is structured in place, the winding has a satisfactory effect. The customer currently plans to add mica tape winding function on this basis. 

Magnetic winding 1mm diameter enameled wire double wire and wound

Micro toroidal                   coil     winding

          Before winding:

         Outer diameter 7.5mm        

         Inner diameter 4mm

         Height 2.3mm

         Enameled wire diameter: 0.17mm

         80 laps.

     In the process of winding the coil on the precision automatic winding machine, the coil enameled wire is placed in a spiral shape in each layer. Since the direction of movement from one layer to the other changes between the opposite directions, part of the wires intersect and part of them lies in the gap of the lower layer. If the guiding structure of the lower layer does not exist, and if the number of layers exceeds a certain limit, the structure cannot be maintained, and disorderly windings are produced. At this time, as a temporary measure, it can be improved by using a separate thicker insulating layer.

       When most of the circumference of the winding is parallel to the coil flange surface, the smallest coil volume can be obtained. If the winding action of the precision automatic winding machine cannot be performed correctly, the self-directing ability of the wire will be lost, and a disorderly winding structure will be produced. In general, the first layer of basic coil mainly determines the location and quality of the winding step. Therefore, in order to make the winding self-guide to be able to execute correctly, the algorithm and accuracy of the precision automatic winding machine are very high requirements.

        It is not difficult to find that when the precision automatic winding machine is winding the coil, the enameled wire needs to enter the winding space as tangentially as possible. In this way, unnecessary excessive bending of the wire is avoided, and the space required for the second layer winding is minimized. For the neatly arranged coils, the winding crossover part should always be located in the area of ​​the wire entering the winding space, and extend continuously in the opposite direction relative to the previous layer of winding in a spiral form. As a result, the larger winding width of the coil results in a larger winding step area along the circumference of the coil. Compared with the enameled wire entry point, the offset created from the first layer to the second layer causes the position of the layer steps to be different. This phenomenon repeats in each layer, thus forming a spiral cross section on the side of the winding. Since the enameled wires cross in the crossing area, the winding height is increased. As a result, a sinusoidal-wound coil with a grounded circular coil will never be circular in cross section, but radially moving windings and layered steps will produce a hump shape.

Precision large torque winding machine:

       With the continuous improvement of the technical level, people have more and more stringent requirements on the winding of transformer coils, hoping that each enameled wire can be like

The ideal sorted arrangement has the following benefits.

       First, in the case of neat arrangement, the enameled wire with limited space accounts for a much larger proportion than the irregular arrangement

       The second is the wire saving.To achieve the same energy density, less neatly arranged copper wire is consumed than if it is neatly arranged.

        The third is the consistency of the product, because the neat wiring, so the copper consumed by each coil is more consistent.

        Of course, there are advantages of heat dissipation and high temperature resistance.

        Despite the above advantages, but for a long time, it was thought that the equipment manufacturers were powerless, and it was difficult for people to do it smoothly with machines.When there is such a requirement, people usually use manual processing.

        Wire the cable by hand, hit an irregular place, stop, handle it manually, and then slowly wind it.For a long time, people have done this.

        Now all this has changed. We have successfully developed a  precision large torque winding machine . Through control and mechanical optimization, we have done so.

        It takes a long time, but now only a simple training is required.The precision large torque winding machine makes what was impossible before possible.

        The cross section of an R-type transformer is like the letter R, so it is called an R-type transformer. The application of R-type transformers in high-power electrical appliances can reduce inrush current. R-type transformers are one of the dry-type transformers. The iron core is made of continuous high-quality oriented cold-rolled silicon steel strip from thin to thick, and then from thick to thin. The final cross-section is close to a circle, and the shape is an uncut closed rectangle, and then passes through a special R-shaped transformer The winding machine winds the coarse secondary on its PBT skeleton. Therefore, the transformer thus manufactured has no noise, low magnetic leakage, low no-load current, low iron loss, and high efficiency; and because the coil is cylindrical, the length of the coil copper wire wound by the R-type transformer winding machine short, so , Low internal resistance, low copper consumption, low temperature rise, low over-carrier motion, and better explosive force than toroidal transformers; in addition, the primary and secondary coils are separately wound with flame-retardant PBT engineering plastic skeletons, thus high electrical strength , Good flame retardancy.

        However, the manufacturing process is more complicated. The second is the winding of the coil. Because it is wound in a closed iron core, the PBT is composed of two parts, and then the R-type transformer winding machine drives the PBT skeleton to wind, and the winding accuracy is affected. A certain influence, one is the shape of its iron core, because its expanded shape is a spinning cone, so its mold and material utilization are relatively low.

        With the development of R-type transformer winding machines, the reduction of manufacturing costs, and the improvement of quality stability, R-type transformers are being favored by more and more electronics industries with their novel and unique structure and excellent electromagnetic performance. Especially suitable for medical equipment, display equipment, audio equipment, office equipment.

         Suzhou REPOSA Electronic Machinery Equipment Co., Ltd. releases high-speed precision synchronous winding machine

Suzhou REPOSAL Electronic Machinery Equipment Co., Ltd. releases precision automatic paint stripping and wire breaking winding machine

    In the inductive coil winding process, the winding process requirements of the coil are quite different.The diameter of the enameled wire varies from thin to thick, the structure of the coil varies from disk to column, and the type of enameled wire ranges from ordinary to self-adhesive wire. Therefore, for a coil winding factory that does not emphasize competitiveness, the machine required is a winding machine with a larger range of adaptation, but often a winding machine with a larger range of adaptation is for each specific specification of coil winding. Whether it is quality or efficiency, it is difficult to have targeted competitiveness.

    In order to keep our customers competitive in the induction coil winding process, we have developed this winding machine-precision automatic paint stripping and breaking winding machine in response to customer needs.

This model is mainly aimed at coils with a skeleton with a larger enameled wire diameter. It has several features, one is the fast winding speed, if it can maintain a faster winding shaft speed when the diameter of the enameled wire is larger, and the other is the winding line is flat. Through control and targeted structural optimization, a compact and consistent coil can be stably wound. Third, there is an automatic paint stripping function. For thicker non-direct welding enameled wires, adding this function is equivalent to combining two processes Integrating into one process, the fourth is to add the function of automatic disconnection.For thicker enameled wires, automatic disconnection improves efficiency, strengthens consistency, and significantly reduces the labor intensity of operators.

For details, please refer to the video. The operation beat of this video is taken during the acceptance of the machine. The entire operation process is fast and stable, but in fact, there is still room for improvement in the efficiency of fixing and dismantling the enameled wire head.

             In modern society, electricity is like a surging torrent, injecting strong impetus into our life and production. With the rapid development of China's science and technology and economy, the demand for electricity is increasing day by day, and the demand for transmission and distribution transformers, as an important cornerstone of the power system, is also rising.

            The transformer is the "heart" of the power system, and the winding coil inside it is a key component of this "heart". The winding quality of the enameled wire and insulating tape in the winding coil directly determines the reliability of the transformer. The quality of this winding depends to a large extent on the performance of the transformer winding machine.

            With the sharp rise in demand for transformers, the performance requirements for transformer winding machines are becoming more and more demanding. A high-performance transformer winding machine must not only meet the requirements of safety, intelligence and high efficiency, but also have high-stability hardware, easy-to-use software and excellent tension control.

            However, at present, the development of China's transformer winding machine industry is still facing many challenges. The level of intelligence is relatively low, the stability needs to be improved, and most of the high-end equipment relies on imports, and the price is high.

            REPOSAL® machine is well aware of these challenges and has been working hard to improve the performance and quality of its products. It continues to increase R&D investment, is committed to improving the intelligent level and stability of the winding machine, and strives to contribute to the development of the industry.

            When the transformer winding machine is working, its coil is usually metal wire and insulating paper, because they have a certain elasticity, the change of coil conveying speed or roll radius will lead to the change of winding tension. For example, in the winding and unwinding process, if the angular velocity of the roll is constant, the change in the radius of the coil will cause tension fluctuations. If the tension is too large, the coil may become thinner or even break; If the tension is too small, the material will be unevenly arranged or wrinkled, which will affect the quality of the transformer winding coil.

            Compared with foreign countries, China's existing domestic transformer winding machine has deficiencies in tension control. Its tension is usually generated by mechanical friction, which is not stable enough, which can easily lead to problems such as sparse arrangement of wires and insulating tapes, and out-of-tolerance of the outer diameter of the coil. In addition, compared with developed countries in Europe and the United States, there is a gap in the overall development level of China's transformer winding machine in terms of processing quality and production efficiency.

            The specific performance is as follows: First, the processes such as wiring and wiring, adding insulation layers rely on manual operation, which is inefficient and unstable in quality. Second, the motor frequently starts, stops and reverses during the winding process, the tension fluctuates greatly, the coil winding is irregular, and the quality is difficult to guarantee. Third, the mechanical structure of the domestic winding machine is relatively simple, and it is not competent for the winding task of complex coils.

            The development of foreign transformer winding machines is relatively mature. The T-600AH automatic transformer winding machine from Trishul.Engineers in India can wind wires and insulating tapes synchronously, with high precision, stable tension and high efficiency. The EFECO 800 automatic winding machine from Tuboly.Astronic AG in Switzerland is even more excellent, with high-speed, high-precision winding and an intelligent cable routing system. The products of companies such as MTM in Canada, LAE in Italy and UPI in Korea also have high intelligence and stability.

            In terms of tension control research, many scholars have been exploring it in depth since the 90s of the last century. Bastogne T, Koc H and other scholars have pioneered theoretical research and modeling simulation. Entering the 21st century, more scholars are getting involved.

            REPOSAL® machine actively pays attention to the relevant research results at home and abroad, and applies beneficial theories and technologies to the improvement of its own products.

            The winding electronically controlled tracking system proposed by Mahawan B et al. in 2001 can still realize the trajectory tracking control of equipment under large interference. In 2008, Wen P et al. designed a tension control scheme that allowed the winding speed to be changed under a certain tension fluctuation while maintaining quality. In 2010, Ponsart J C et al. applied the observer theory to a transformer winding machine to improve the accuracy of tension control. In 2017, Mahesh Ghate et al. optimized the tension system for a specific winding machine and showed good robustness. In 2020, Ma Quanjin et al. designed a dual-PID tension control system to address the tension fluctuation problem in a 3-axis fiber winding machine applied with filament winding technology.

            Since the 70s of the last century, China has begun to develop transformer winding machines, and has achieved certain results through imitation and the efforts of scholars. However, due to the monopoly of foreign core technologies, there is still a gap with foreign countries, especially in terms of manufacturing processes and control schemes.

            At present, the domestic transformer winding machine is mainly in the semi-automatic stage. For example, F. of Dongguan Zongheng Electromechanical Technology Co., Ltd. TWloo CXL transformer winding machine for small and medium-sized transformer coil winding. The ZBR.800/1000/1200 multi-head automatic wiring winding machine of Jiangxi             Yibo Automation Equipment Co., Ltd. can realize automatic wire arrangement.

REPOSAL® machine has been committed to promoting the development of domestic transformer winding machine in the direction of full automation and intelligence, and constantly optimizing its own manufacturing process and control scheme.

            However, there is still a breakthrough in the layout of insulating tape and tension control in China, which greatly affects the quality and production efficiency of the winding coil. Therefore, it is of great significance to develop a control system that can automatically arrange wires and insulating tapes with constant tension.

            Tension control is a key technology for transformer winding machine equipment. If the tension is too small, the wire or insulating tape will slacken, accumulate and wrinkle; Excessive tension can cause it to deform, stretch excessively, or even break. For transformer winding machines, the tension control condition directly affects the compactness between the layers of the winding wires.

            At present, there are three main schemes of tension control: manual, semi-automatic and fully automatic. The manual control needs to be adjusted manually in stages, the semi-automatic control adjusts the tension by detecting the change of the roll diameter, and the fully automatic control is adjusted by directly measuring and feeding back the tension data by the tension detector.

            In the 80s of the last century, manual tension control was mostly used in China, which was gradually replaced due to the increase in demand. Since the beginning of this century, domestic scholars have conducted in-depth research on the automatic tension control system for rewinding and unwinding.

            In 2005, Yang Tao and others from Tianjin Polytechnic University used a PLC design scheme to accurately control the winding speed of fine enameled wire. In 2010, Shi Yaoyao et al. studied the discontinuous coil process and realized winding through the PID algorithm. In 2018, Zhiyong w et al. established a constant tension control system for the problem of triaxial fiber winding machine. In 2020, Song Chenliang et al. optimized the tension adjustment effect of the winding machine through the pendulum tension adjustment mechanism and the deformed PID control algorithm.

            REPOSAL® machine has never stopped exploring tension control solutions, and constantly tries to innovate to enhance the competitiveness of products.

            However, due to the complex structure of transformer winding equipment and many influencing factors, the tension control system has nonlinearity and coupling in different situations, which is still a difficult point in equipment control. Constant tension control is very important to ensure the quality of winding, so it is of practical significance to study the constant tension control system suitable for industrial production.

            In the winding coil structure of distribution transformer, insulating paper tapes need to be arranged between the wire layers, so the transformer winding coils are usually wound in layers. The winding process is more complicated, the pilot wire is unwound and sent to the spindle mold base, during which the oscillating roller adjusts the tension and speed, and the spindle motor drives the spindle winding. Then the insulating tape is unwound and sent to the spindle mold base, and multiple coil rolls cooperate to adjust the tension. Finally, a plurality of motors work together to drive the spools and other spools for the first layer of winding and arrangement, after the completion of the wire motor reversal, the pressure roller shears the insulating paper, the glue sprayer glues, and then the next layer of winding.

            Taking Switzerland EFECO 800 transformer winding machine as an example, its mechanical structure mainly includes spindle mold base, winding spindle, glue spraying machine, etc. The winding spindle includes a spindle motor, a reducer, etc., which drives the spindle to rotate and the foot switch controls the start and stop. The wire winding mechanism has pay-off wheels, adjusting handwheels, etc., and the insulating tape winding mechanism has tension feedback devices. The wiring mechanism is composed of a wire spool, a wire trolley, etc., which can achieve accurate wire arrangement.

            For transformer winding machines, the tension control directly affects the compactness between the winding lines. In practice, the machining accuracy and the performance of the sensing device will have an impact on the tension control. For example, the change of reel diameter, the start-stop and acceleration and deceleration of the reel, the accuracy of equipment manufacturing and assembly, the forward and reverse rotation of the motor, and the hardware performance.

            There are three ways to test tension. Directly using the tension sensor to measure, the operation is simple but the limitation is large; Floating roller tension detection, the measuring device is flexible but the accuracy is low; Floating roller/feedback composite tension detection, high accuracy but complex method.

            In the process of arranging the transformer winding machine, the adjustment of the wiring mechanism and the winding position and the control of the wiring angle are the key to ensure the compactness of the winding wire.

            The cable arrangement mechanism measures the angle through the rotary encoder on the spindle and transmits the data to the controller, and the controller drives the wire motor after processing to realize the speed coupling of winding and wire arrangement.

            In the actual winding, the tension of the wire and the insulating tape should be kept constant and cooperate with the wire arrangement. In the automatic wiring control scheme, the main controller controls the motor unit to work together, the spindle and the wiring mechanism cooperate with the layered winding, the encoder feeds back the data in real time, and adjusts the speed of each axis according to the control algorithm to ensure the accuracy of the wiring.

            The angle of the cable is very important, too large or too small will affect the effect of the line. When winding, the line is adjusted according to the change in angle, the feed rate is brought in, and the overall trajectory is followed. Since winding is carried out in layers, divided into wire layers (odd layers) and insulating layers (even layers), the wire laying process can be divided into multiple stages and cycles.

            The automatic wiring of the transformer winding machine has high requirements for the motor control algorithm, which requires the coordinated operation of the motors of each shaft and the close cooperation of the drive actuator to jointly complete the automatic winding and arrangement of the transformer coil. The common multi-motor cooperative control structures include parallel synchronous control, master-slave motor control, cross-coupling collaborative control, adjacent cross-coupling control and deviation coupling step control, each with its own advantages and disadvantages.

            In conclusion, transformer winding machines are very important in the power field. Although China has made certain achievements in this field, it still needs to make continuous efforts to strengthen independent research and development, improve the technical level, narrow the gap with foreign countries, promote the development of the industry, and contribute more to the power industry. REPOSAL® machine will continue to uphold the spirit of innovation and enterprising, and make unremitting efforts to improve the overall level of China's transformer winding machine.

          The linear motor winding machine developed by Suzhou REPOSAL® Electronic Machinery Equipment Co., Ltd. successfully completed the test, achieved success, and was successfully put into production.

          At present, in traditional linear motor winding machines, the stator coils are individually wound and then assembled on the linear motor core in sequence, and then welded between the stator coils. The process is many, the efficiency is low, and there are many process nodes such as manual intervention assembly and welding. At the same time, the quality is unstable, which affects the cost of the traditional linear motor for a long time. The successful research and development of the linear motor winding machine of this specification will further reduce the cost of the linear motor and improve its quality.

          Based on the process of this linear motor winding machine, the company has reached a further research and development agreement with long-term cooperative customers to replace the traditional circular stator coil inner winding process. There are two reasons for its cost to apply the company's linear motor After the winding machine, there is a very large drop space. One is because the existing inner winding stator coil has a toroidal core, so the utilization rate of the material is low. The current plan is to design it as an unfolded type. The utilization rate will be at least doubled. The second is the inner winding of the stator coil. Due to technological limitations, its winding method can only be wound by a single wire. The REPOSAL'slinear motor winding machine winds three windings at the same time, and its processing efficiency is tripled. The combination of the two aspects will greatly reduce the cost of the inner winding stator coil.

          At the same time, Suzhou REPOSAL® Electronic Machinery Equipment Co., Ltd. will further optimize the design and production process, and strive to continue to reduce the cost of the whole machine under the existing cost advantage, so that the production company can save materials and improve efficiency, while also greatly reducing The purchase and use cost of the winding machine-make REPOSAL's partners more competitive.

Ring wrap tape machine

      We will now demonstrate the operation of the loop coil strapping machine again, take the product, put it in, and then buckle this storage ring. Note that the insulating tape must pass between the two blades of the scissors After the fixed storage coil count is reached, the toroidal coil wrapping machine will rely on it to cut the insulating tape. Then, one end of the tape can be passed through any position of the bearing evenly distributed on the storage ring. After passing through, take the head of the insulating tape and hold it with the head, and then press and start with the right hand. The entire loop coil is covered with insulating tape It's done automatically.

Setting of counting direction of winding machine controller:

         The REPOSAL's  winding machine controller has complete functions and a wide range of applications.Some customers have purchased our winding machine controller.As soon as we delivered the counting sensor, users sometimes find that when they are installed in the winding machine, the counting It will start counting from 9999.9 and become smaller and smaller. This is just because when you don't pay attention, install the counter in the opposite direction.At this time, we don't actually need to disassemble the installed machine. We have taken this into consideration. You need to change the counting direction on the controller.The video below shows that if you use our winding machine controller to change the counting direction.

Wire passing method of side-slip loop coil winding machine:

         For the side-slip toroidal coil winding machine, the setting method of the controller is basically the same as the belt-type toroidal coil winding machine, the difference is that the winding direction and the storage direction, when a person stands on the right side of the winding machine, The storage direction of the belt loop coil winding machine is counterclockwise, while the storage direction of the side slip loop coil winding machine is clockwise, and when winding, the belt loop coil winding machine and the belt loop The direction of the coil winding machine is the same, which is counterclockwise.

      Generally, in order to facilitate the observation of the winding situation, we can press the "Start" button twice in the winding phase. At this time, when we turn the rotating handle on the left side of the ring coil winding machine stand by hand, we can easily and clearly Observe the winding process of the enameled wire.

         As shown in the figure, this miniature permanent magnet trip coil is widely used by ABB, EATON Muller compact circuit breaker, and has a compact structure. On a tiny metal structure bracket, a suction coil is wound that is closed to the metal structure. It seems simple, but its design technology is very strong. Therefore, it has been the industry enterprises in this kind of products to achieve the domestic industry barriers.

         With the attitude of professional focus and the trust of advanced customers in the circuit breaker industry in Mongolia, REPOSAL® winding machine has gone all out to successfully reverse crack this technological process and help customers of REPOSAL®  winding machine to make this product domestically smoothly.

Stator coil winding machine:

       Acceptance of winding machine.

       AC permanent magnet synchronous motor stator coil, iron core length 180mm width 40mm, enameled wire diameter 1.9mm (including insulation film thickness)

      There is a resin sheath before the iron core is wound with enameled wire. The R angle is less than 0.3mm.

       The main clamping surface of the winding tooling is completed with one clamping and cutting.

           This video explains the structure of the high-frequency transformer winding machine. The general simple winding machine structure is roughly divided into several parts. The first part is the winding part, which is the winding shaft, and the second part is the winding part, which is the winding shaft. The mechanism that makes the enameled wire reciprocate while rotating. The third part is the wire passing mechanism, that is, the part between the enameled wire from the original cylinder to the tension mechanism. This part is usually composed of some bracket parts, and the fourth part is the tension part. To provide unequal tension required for winding the enameled wire on the coil, the fifth part is the winding head part, that is, the winding machine has passed the tensioner and obtained tension, and the part of the mechanism that will be wound on the coil. The high-frequency transformer is because of its design. Targeted, compared with the general simple winding machine, because its windings are more, the structure is compact, and the product requirements are not high, so there is no tensioner part, but because high-frequency transformers mostly require wall tape and insulating tape, So compared with the general simple winding machine, these two parts are more.

          Let's briefly introduce the structure of this transformer winding machine.

          Why did he name this winding machine the transformer winding machine?

          Because it can support multiple enameled wires of different specifications at the same time.

          Every enameled wire is from this position to this position.

          Then pass the ceramic circle.

          Then go through wool felt.

          Then there are different holes from small to large.

          Here are 4 such ceramic circles.

          Like this.

          In this way, he can clamp it all at once.

          The skeleton of the transformer is installed in this position.

          It can be wound with 4 enameled wires of different specifications at a time.

          Enameled wires of different specifications.

          This position is used to put the retaining wall tape on both sides of the high-frequency transformer skeleton.

          This position is used to place the insulating tape of the high-frequency transformer.

          So this machine is suitable for winding high frequency transformers.

Switching-and-debugging-between-two-programs

      This article introduces the test of designing tension control system to minimize the change of tension. Perform theoretical analysis on simulation. The simulation results show that the tension of the enameled wire is frequently fluctuated due to the length change caused by the speed change. The model's tension sensor verifies the prediction. The key to successful design is to eliminate changes in tension. We added a tension system that includes a high-speed cylinder to replace the traditional wool felt and spring mechanism. The simulation results showed that the new prototype system almost doubled the winding speed and the ability to withstand tension fluctuations.

One. introduction

      Countless transformers are produced every year. Together with power plants, substations and power lines, distribution transformers provide electricity for businesses and residential buildings across the country. Transformer manufacturing involves the production of winding coils. These coils are usually made of an insulating paper layer sandwiched between a pair of copper wires. They are usually round or rectangular.

      A consistent tension must be maintained on the coil windings. The shape of the coil has a major influence on the tension applied by the tension. For a circular coil, the tension does not change significantly, but a rectangular coil is different. As a rectangular coil, the tension changes sharply with the position of the drop point. As shown in the figure, this change in speed is caused by the changing length of the line. In the case of a round coil, this is not a problem, because the contact points of the wires on the coil are fixed.

Toroidal transformer winding machine

The company has the advantages of R&D and production of electronic transformers and transformers in the whole factory equipment. Different from many assembly manufacturers in the industry, we have accumulated many years of experience in R&D and production in the winding machine industry and developed a new generation of toroidal coil series winding The equipment is widely used in the manufacturing industries of toroidal transformers, transformers, voltage regulators, inductance coils, etc., and has been well received by the industry; Suzhou REPOSL will continue to understand user needs and strengthen technical research and development and after-sales service levels, and provide customers with more professional and high-quality products and service.

Technical features of our toroidal transformer winding machine: Using CNC digital intelligent program controller, stable work, simple operation, with a number of industry-first advanced and practical functions. The core components such as the thread storage ring and the thread belt are made of high-quality steel through multiple processes, which are durable and not deformed. It adopts advanced control circuit and has fault alarm function. The function switches are all controlled by two lines, which is easy to maintain and replace. The operating speed is set separately in the storage and winding state, which can automatically realize the fast storage and low-speed winding operation. The automatic operation function can also be used in the taping machine mode. The operation is simple and the use efficiency is high. When processing multi-winding products, multiple storage and multiple winding procedures can be preset, which is suitable for products with multiple windings but different wire diameters/numbers of turns, or products with insufficient wire storage in a single time, eliminating repeated installation Clamping and manual operation improve production efficiency. Multiple sets of wire density can be preset, and the device can automatically change the preset wire density when winding. When processing multi-winding products, each winding with different turns can be evenly arranged at a preset angle. Double frequency conversion proportional drive, automatic operation or pedal speed regulation can be selected. The speed can be adjusted steplessly, and the appropriate winding speed can be set according to the process requirements of different products. Features: The gear winding machine has the characteristics of large winding torque, high opening size of the gear ring roof ring, a large amount of wire storage and a large range of suitable winding diameters. It is the most versatile Winding model; suitable for products with thick winding diameters, neat wiring requirements and multiple parallel windings, such as small toroidal transformer secondary windings, high-power 驽

         Transformer insulating crepe paper has good mechanical strength, high withstand voltage strength, wrinkles on the surface, and a certain degree of toughness. Moreover, it is easy to cut. After the transformer is wound and formed, it still maintains a certain strength in the oil immersion of the rear tooling. This feature can very well protect the enameled wire of the transformer from being squeezed and broken, that is, it meets the insulation requirements. It also meets the mechanical performance requirements.

         Therefore, it is widely used for transformer insulation. Generally used in transformers, but less used in transformers, because the core structure of transformers is annular, because the surface of the insulating crepe paper has wrinkles and friction is large, so the annular wrapping machine is used. Winding is more difficult, so in general, if crepe paper is required for the transformer coil, manual winding is used. We have successfully overcome this problem by improving the details.

Winding machine: As the name implies, a winding machine is a machine that winds a linear object onto a specific workpiece.

　　The scope of application of the winding machine:

　　 Most electrical products need to use enameled copper wire (referred to as enameled wire) to be wound into inductance coils, which requires a winding machine.

　　 For example: various motors, fluorescent lamp ballasts, transformers of various sizes, televisions. The mid-periphery and inductive coils used in the radio, the line output transformer (high-voltage package), the high-voltage coil on the electronic igniter, the mosquito killer, the loudspeaker, the earphone, the voice coil of the microphone, the various electric welding machines, etc. can not be cited one by one. All coils need to be wound with a winding machine.

　　 In the textile industry, cotton yarns, man-made fiber yarns, etc. are used to wind all kinds of yarn balls and frays suitable for textile machines. These require a winding machine to wind.

　　 Type of winding machine:

Commonly used wire winding machines are mostly enameled copper wire (winding inductance coils for electronic and electrical products), textile wire (winding yarn frays and coils for textile machines), and winding electric heating appliances. Electric heating wires and solder wires, wires, cables, etc.

　　There are many types of winding machines, which can be classified into general-purpose and special-purpose types according to their uses;

The customer requires winding multi-strand steel wire rope with a total diameter of 3.5mm, multi-layer winding, which requires stability and speed.

                 Radiofrequency ablation has ablation and cutting functions, and the main therapeutic mechanism is thermal effect. Radio frequency refers to radio frequency, frequency up to 150,000 times per second of high frequency vibration, but it does not belong to the division of bands in radio communication.

            The coiling process is completed by continuous test and optimization of the coiling machine.

            The working flow of this winding machine is as follows:

            1. The active wire feeding device of the radiofrequency ablation catheter winding machine ensures that the wires are constantly connected and not tied.

            2. Double fold section A measurement line.

            3. Manual folding head.

            4. Manually fix the thread head (Two schemes are tentatively proposed for fixing the thread head)

            4.1 Fix the starting position with glue. The fixture locks the PEEK tube.

            4.2 Kangtong wire is hung on the feature of steel pipe. Glue to fix the ends after wrapping.)

            5. Press the start button of the radiofrequency ablation catheter winding machine to wrap.

            6.(During the winding process of the radiofrequency ablation catheter winding machine, both AB and AB segments have adjustable tension)

            7. Wrap the jump grid to the specified position (the specific hop length can be set, and the rotation Angle can be set.

            8. After the radiofrequency ablation catheter winding machine is finished, the feeder stops at the end and maintains tension.

            9. Fix the end of the line by manual dispensing

            10. Both ends of the radiofrequency ablation catheter winding machine are coaxial, and the rotation direction is synchronized.

            11. Adjustable pre-drawing force is required at both ends of the locking shaft core.
