    Precision winding machine

      Precision winding machine For general winding machines, including CNC and automatic winding machines, only the set number of turns of enameled wire is required to be wound, and the appearance is roughly flat, but there are some special high-demand occasions , It is required that the arrangement of enameled wires must be neat without a random winding.

       This kind of coil has several advantages. First, the consistency of inductance is very high. Second, the enameled wire occupies less space, and the enameled wire can reach the ideal neat arrangement. Third, the energy density is high. Fourth, the high temperature resistance performance is better. , The enameled wires are in line contact, and in the case of random winding, the superimposition between the wires will have a little contact, and it is easy to break down under high temperature and high pressure.

       In order to achieve a stable and neat arrangement, in addition to the requirements for enameled wires, compared with general coil winding machines, high requirements are put forward for the electronic control, mechanism design and manufacturing accuracy of structural parts of the fine winding machine.

           Guidance communication has an excellent application prospect, but the guided fiber wire package needs to be wound long distance without defects, but because the surface of the fiber is smooth, brittle and easy to break, as well as the residual stress generated by the micro bending will make the signal attenuation, so it is more difficult to wind than other fibers, making long distance fast fiber automatic winding without defects has become a major issue. REPOSAL® winding machine, as a professional winding process solution provider, has been developing process research on precision winding of guided fiber wire packages for many years. Good progress has been made and REPOSAL® special winding machine for guidance fiber wire wrap developed by the winding machine can set reliable process instruction information according to process requirements and accurately execute control commands to finally finish the long distance guidance fiber wire wrap without defects. In the whole research project, we focus on solving three problems of guidance fiber optic wire wrapping system: tension control. Winding system, feeder system, and expand as follows.

 The precise winding process ensures the efficient transfer of energy, thereby improving the efficiency and consistency of ablation. The uniformity of the precision wound coil affects the temperature distribution of the ablation area, avoiding local overheating or heat deficiency, which is essential to ensure the ablation effect and reduce complications. The stability of the winding process ensures the reliability of the operation. The high-quality winding process withstands stretching and bending during surgical operations, reducing the risk of breakage or functional failure. High-quality winding processes have a longer service life and are able to maintain stable performance through multiple operations, thereby reducing medical costs and improving resource efficiency. The quality of the winding process also affects the precise control of the ablation process. The high-precision winding process helps physicians to more precisely control the size and shape of the ablation area to achieve optimal treatment results.

Moreover, the RFA catheter winder is designed with operational safety in mind, reducing potential risks during operation and protecting operators and products from damage. It can adapt to different types of radiofrequency ablation catheter production requirements, and has good flexibility and scalability. The structure and design of special winding machines are often more simplified and easier to maintain and maintain, thus reducing long-term operating costs.

The advantages of radiofrequency ablation catheter winding machine are mainly reflected in professional design, high efficiency production, precise control, quality stability, easy operation, material saving, safety, strong adaptability, low maintenance cost and technological innovation. These advantages make the radiofrequency ablation catheter winding machine an indispensable key equipment in the production process of radiofrequency ablation catheter.

In the manufacture of power transformers, winding the transformer coil is a super important step, you think, the transformer coil is wound more firmly and neatly, the strength of the transformer and the ability to protect against short circuits can be greatly improved. However, most of the current transformer winding machines have to rely on manual extra sorting of the coil, the entire equipment is low in automation, and the production efficiency is not high, so the development of an excellent large transformer winding machine is a crucial thing for our company.

We have studied the main shaft technology of transformer winding machine, the relationship between compaction force and winding quality, and the control of compaction force. According to the principle and process flow of transformer winding, we put forward a whole design scheme of large transformer winding machine, including mechanical structure and electrical control. Mechanically, we simplify the complex structure of traditional transformer winders. In terms of electrical control, we ensure the stability of the motor when it starts and stops, and ensure that the winding coil is evenly tightened during the winding process. For the core parts of the transformer winding machine, spindle system and pressing device, we have calculated and selected the types and parameters. With the compaction device, we are able to provide real-time axial and radial compaction forces during the winding process of the transformer winding, which is very effective for improving the tightness of the winding.

The static analysis of the radial compaction device of the winding machine is also carried out by using finite element method, and the structure optimization is carried out according to the analysis results. We find that as the number of layers and turns of the winding increases, the required axial and radial compression forces change accordingly. By analyzing the experimental data, we find that there is a maximum value and a minimum value in the range of quality requirements, and it is the most reasonable choice to make the compression force approximately proportional to the number of layers and the number of turns.

The large transformer winding machine developed by our company has been preliminatively debugged and put into the market. After testing, the performance parameters of this transformer winding machine are in line with the design requirements, and the operation is stable and efficient. It can be wound to make a tight and regular transformer winding coil, and has been fully recognized by the market.

As a power grid equipment, power transformer converts voltage through the electromagnetic induction between the winding coils of the transformer. With the continuous development of the market, higher requirements are put forward for the manufacturing level of transformers, and the market needs more energy-saving and efficient transformers. Therefore, the optimization of the transformer manufacturing process is particularly critical. Quality and performance depend on the process equipment. The technical level of the transformer winding machine directly reflects the manufacturing level of the transformer. Therefore, accelerating the development of transformer winding machine is an important guarantee to improve the performance of transformer.

The winding coil of the transformer is the core component of the transformer and constitutes the electromagnetic induction part of the transformer. It generally includes high voltage winding and low voltage winding, respectively connected to the high voltage grid and low voltage grid. The winding of large power transformers usually adopts concentric winding, that is, the high and low voltage transformer winding coils are centrally set on the core column. The manufacture of transformer winding is the core process of transformer, and its quality plays a crucial role in the performance of transformer, affecting the appearance of transformer size, weight, mechanical properties, insulation and heat resistance and other important indicators.

In the past, the production of transformer winding coils relied on manual, and workers had to wind insulated wires manually to the winding die frame in accordance with the process requirements. Turns calculation also have to rely on manual, this old-fashioned method is inefficient, and because the worker's skills are not strong enough, the quality of the winding coil is poor, the number of turns may be miscalculated or missed, and ultimately lead to the finished winding coil performance can not be guaranteed. Later appeared semi-automatic transformer winding machine, which is driven by the motor to rotate the spindle to wind the transformer winding coil, although it improves the production efficiency, but the wiring work still has to rely on manual, only suitable for flat winding transformer winding coil winding, and winding head winding, welding and other operations must still be completed manually, so the product quality is not stable.

Later, with the emergence of TTL logic gate circuits, in the mid-1970s, with the development of CMOS technology, various types of equipment program control a large number of applications of digital integrated circuits, Western countries and Japan and other industrial powers have emerged CNC winding mechanism manufacturing industry. These CNC transformer winding machines represent the advanced level of winding mechanism manufacturing technology, especially the winding equipment produced in Japan, Italy, the United States and Germany is the leading technology.

Now the transformer winding machine as the core parts of the transformer production equipment, the market demand is very large, and the transformer manufacturing enterprises at home and abroad attach great importance to the development and application of advanced technology of transformer winding machine. Domestic transformer winding machine production enterprises are small, insufficient technical reserves, limited research and development funds, so there is still a big gap compared with foreign advanced products, the market share is low, unable to compete with foreign countries. To solve the key technical problems of transformer winding machine is the key to improve the quality of domestic winding equipment and enhance the market competitiveness. In order to meet the demand of transformer manufacturers for high quality and low price winding equipment, especially large transformer winding machine, on the basis of learning from foreign advanced experience, combined with domestic research results, the development of large transformer winding machine has important significance and practical value.

             Your factory is using a traditional winding machine, your wire machine structure is reasonable, high mechanical accuracy, the motor is also used a big brand of motor, but in the winding of precision coils, there will be a high defect rate, you carefully analyze before improving various factors - equipment structure, processing accuracy, tooling accuracy, skeleton accuracy, enamel wire quality, tension control, etc. But it still doesn't solve the problem. But to tell you that it's not just a hardware problem, but an algorithm problem, may surprise you. Because in your opinion, every time the spool is transferred, the spool has a corresponding response, but in fact, you may not have considered that in the winding process of the precision coil, the wire guide pin is connected at both ends of the coil, and the sudden change in speed may cause the coil to cross the line and be raised. These defects can degrade the performance of the coil.

            To solve this problem, we propose an acceleration and deceleration method based on 5-segment S-curve. The algorithm uses linear acceleration or deceleration at the end and end of the line motion control to help reduce coil defects. We first verify the feasibility of the algorithm by using ADAMS software. The software simulates the motion of the precision winding coil and obtains the velocity curve and displacement curve during the motion. Later, the experimental results show that the method of adopting S-curve in the alignment speed control can reduce the coil defect by up to 50%. This shows that the 5-section S-curve motion control algorithm is a promising method to improve the precision and efficiency of the winding process of electric precision coils. By using this algorithm, coil manufacturers can reduce the risk of coil defects and improve coil performance.

            Winding machine is a special production equipment for precision winding coils. They can be divided into stator winding machine, flying fork winding machine, ring winding machine and flat winding machine according to the working mode and object. Different types of equipment are suitable for the production of different objects. For example, the stator winding machine is mainly used to produce motor stator coils, while the parallel winding machine is used to produce electromagnetic switching coils.

            Ordinary algorithm of parallel winding machine in the production of precision winding coil products, although our mechanical structure, parts processing accuracy has been done very well, but often there is a problem of low wiring accuracy. In the process of winding a line coil, there are two main movements, one is the rotating movement of the skeleton, which is called winding movement, and the other is the translation movement of the guide needle, which is called wiring movement, and wiring transport is matched with winding movement. After years of technical accumulation, we analyze that the leading role in the alignment accuracy is the alignment movement of the guide needle. Therefore, if you want to improve the alignment accuracy of the coil, you need to optimize the alignment movement of the guide pin.

            In fact, we have always believed that the winding machine is equivalent to the lathe in the electrical industry, its importance is self-evident, so for its accuracy, there have been many experts and scholars to study this.

            Some people studied the mathematical model of precise alignment based on axial pressure compensation around the axis in the process of alignment. The axial pressure was used to improve the alignment regularity of the coil, and the mathematical model was established according to the analysis of the end point of the coil alignment, which improved the alignment accuracy of the coil.

            Some people use the 5-section S-curve control algorithm and the 7-section S-curve control algorithm respectively in the research. In motion control, the 7-section S-curve is more complicated than the 5-section S-curve control. This method has achieved more results in the field of CNC machining, but it is not mature in the field of winding machine.

            The tension instability caused by the friction between the enamelled wire and the conductor nozzle during coil winding has been studied, which leads to the uneven wiring of the coil and the breakage of the enamelled wire.

            Some people have studied the low efficiency of the winding machine in the traditional winding control because of the inertia error in the process of the winding machine. Instead, the servo motion wiring and the inertia error supplement are used to improve the control efficiency of the winding machine.

            PLC control is commonly used in the winding machine wiring control system, through PLC control servo motor can realize the winding machine wiring control, both PLC control stability and high precision servo motor advantages. However, there is a sudden impact of guide pin speed in the coil alignment of parallel winding machine, so it is necessary to further optimize the change of guide pin running speed to improve product quality and the smoothness of wire alignment speed. The S-curve algorithm is a kind of smooth transition of speed in the process of motion, which is often used in machining to solve the problem of breaking the tool caused by speed impact and improve the precision of machining products. In the winding machine, the speed of the guide needle can be changed into an arc smooth transition by controlling the movement track of the guide needle, improving the alignment accuracy and product quality.

            To sum up, an algorithm based on 5-segment S-curve motion control is proposed to solve the problem of velocity shock in the process of coil alignment by analyzing the law of coil alignment. ADAMS software is used to simulate the trajectory of the guide pin to verify the feasibility of the algorithm. And the application of the example proves that the 5-section S-shaped curve can effectively solve the phenomenon of crossing and protruding in the process of winding, and improve the precision of winding.

            Coil wiring principle

            The winding method is flat winding, that is, the enameled wire moves synchronously with the guide pin and always keeps perpendicular to the skeleton during winding. The frame is driven by the winding motor with the guide needle movement, the enameled wire is wound on the skeleton, in which the guide needle is located in the wiring arrangement mechanism and the winding mechanism are two independent mechanisms. The winding mechanism is divided into three stages according to the motion process of the guide pin, namely acceleration and deceleration stage, uniform speed stage and end point return stage. The acceleration and deceleration stage can be divided into two parts: acceleration stage and deceleration stage. In the early stage of the alignment movement, the guide pin speed from zero to uniform speed belongs to the acceleration stage. At the end of the alignment movement, the process of decelerating until the speed reaches zero is a deceleration stage. The middle constant velocity stage is the constant velocity motion stage of the guiding needle. The terminal reentry stage is a process in which the guide needle accelerates backward again after slowing down and stopping. Here we explain:

            Acceleration and deceleration stage

            In order to arrange the lines evenly, the two movements of guide pin movement and skeleton rotation should meet certain coordination relations during acceleration and deceleration stage. The time for the guide needle to move one diametral width distance must be equal to the time for the skeleton to rotate once, that is, the guide needle to move just one diametral distance when the skeleton rotates once.

       Below we introduce the structure of this toroidal coil winding machine. This part is the controller and this part is the clamping base. We control the product clamping by opening and closing the handle. This position is the storage ring. The enameled wire is stored on the storage ring first, and then wound around this product. This position is a manual winding handle. Turn this handle. The steel plate can be driven manually. The steel ring has an opening. This position is an opening. The opening is opened and closed by sliding the handle up and sliding to the left. . This position is called the crimping plate, and this position is called the baffle. After the line is removed, its degree of tightness is determined by the tension of the belt. The tension of the belt is adjusted by the tension adjustment knob. When adjusting the tension of the belt, first loosen this And then rotate the handle. When rotating the handle, there is an idler wheel. When the idler wheel goes in, the tension of the belt will increase, so that the winding of the enameled wire will become tighter.

  Stable, high-speed and safe U-shaped core coil winding machine

The U-shaped coil winding machine is suitable for the winding of the bottom edge of the U-shaped core.Usually, the center of the U-shaped core is difficult to coincide with the rotation axis of the winding machine, resulting in a large vibration of the winding machine. , Affecting efficiency.

This type of winding machine developed by our company does not rotate the U-shaped iron core, only reciprocates, and rotates around the product to reduce vibration and improve efficiency.

      With the optimized clamping method, it only takes 2 seconds to complete the clamping.

      Therefore, the rotating parts of this type of machine have a large diameter and a high speed.There are similar machines on the market, and the larger ones do not have a protective cover. Safety accidents often occur.This machine of the company has a protective cover design.

High-speed precision winding machine SP-112DHS

      Manufacturers of small motors and coils are faced with the need to increase production capacity and improve product reliability, and they need to continuously reduce the damage to the insulation properties of enameled wire caused by coil winding and assembly. Due to the large stretch during the coil winding and assembly process, the insulating layer of the enameled wire must have good flexibility, and the enameled wire should also have good formability (softness of the wire).

        1 The formability of the enameled wire The mechanical properties of the enameled wire are divided into the mechanical properties of the conductor and the paint film. In the process of winding the enameled wire, in the wire embedding process, and in the electrical products using the enameled wire coil as a component, mechanical stress acts on the enameled wire during operation, so the enameled wire may be elongated and the paint film is damaged. etc. phenomenon. Therefore, enameled wire has the requirements of elongation, rebound angle, softness, tensile strength, paint film elasticity, paint film adhesion and scratch resistance.

        1.1 Mechanical properties of conductors: softness, elongation, rebound angle, and tensile strength.

        Elongation reflects the plastic deformation of the material and is used to assess the ductility of enameled wires. The springback angle and softness reflect the elastic deformation of the material and are used to evaluate the softness of the enameled wire. The tensile strength is related to the recovery recrystallization degree of the conductor and the grain size of the recovered tissue. The tensile strength, softness and elongation reflect the quality of the copper material and the degree of enameled annealing, which have a great impact on the quality of the winding. great relationship.

        In the process of enameled wire coating, if the number of paint passes and the number of loops is too large, and the diameter of the guide wheel is not large enough, the wire will be continuously deformed by alternating tension and compression, resulting in the distortion of the lattice. It breaks easily when stretched. When the enameled wire is running, the wire is subjected to excessive tension, which will make the wire thinner. At this time, due to the displacement of atoms or ions on the lattice due to sliding, residual internal stress has been formed, so the wire is brittle and elongated. rate and softness rate decreased.

Magnetic winding 1mm diameter enameled wire double wire and wound

     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.

        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 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.

             On August 6, the first ultra-precision flow tube metering heating wire winding machine independently developed by Suzhou REPOSAL® Electronic Mechanical Equipment Co., Ltd. successfully completed the test, and the performance of each index reached the level of the industry in advanced foreign countries.

              At present, the ultra-precision flow tube, a metal tube with a diameter of 0.4mm, a wall thickness of 0.1mm, an inner diameter of 0.2mm, and a special metal wire of 0.03mm are wound. There are single-layer winding, double-layer winding, and double-layer butt-joining winding. Flow tube is required There is no deformation at both ends and the metal wires are arranged neatly. This process technology has been monopolized by foreign companies for a long time, and the price is high, which severely restricts the research and achievement of ultra-precision flow meters in China.

       Ultra-precision flow tube metering heating wire winding machine is an important symbol of independent innovation ability. The research of this equipment has broken through many key technologies of precision winding technology and optimized the process and mechanical structure. In the next step, Suzhou REPOSAL Electronic Machinery Equipment Co., Ltd. will further optimize the design and production process, reduce the cost of the whole machine, make it better to market, and accelerate the application and industrialization of localized precision winding machines.

      Research and development of 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.
