New product release

　　　          REPOSAL®  Winding Machine successfully overcomes the difficulty in the winding process of closed coils of fixed-length titanium plates with loops.

      These tiny looped titanium plates are shown here, small metal structures approximately 12mm long, 4mm wide and 1.5mm thick, and have a row of four circular holes through them, two of which are for The main body pulls the suture through, and the other two upper holes are used for the passage of another group of seam lines. The structure is small in size, and it is necessary to form a closed connecting loop through the structural member, and the closed connecting loop is formed by twisting the yarn fibers of the loose structure. A closed high-strength braided coil is passed through the middle, which seems simple, but its core technology is reflected in the Loop, that is, a high-strength coil, which is woven evenly, tightly, non-woven, and without joints.

        This kind of titanium plate with loops is divided into two types, fixed-length type and adjustable type, especially the fixed-length type, whose length ranges from 15mm to 60mm. It is necessary to wind this closed loop in the middle of a titanium plate with such a small volume. Coils, and because the number of colonies cannot exceed the standard, cannot be wound by hand, but must be wound by 

equipment, which is extremely difficult to process. Its structural parts are small in size, and the diameter of the holes is only 1-1.5mm. It needs to form twisted yarns under such conditions, so this product has always been processed manually by hand, and its efficiency is low and consistent. Sex is hard to guarantee.

Because of the small size of the structure, the diameter of the hole is only 1-1.5mm, and it needs to form twisted yarn under this condition, so this product has been processed manually, and its efficiency is low. Consistency is difficult to guarantee.

　　　REPOSAL® Winding Machine successfully developed this equipment according to the customer's request, completed the simultaneous formation of a closed loop (including fiber bundles with a loose structure) and passed it to the porous structural parts, and maintained the twisted structure, which greatly improved the closed loop. The winding efficiency, in addition to obtaining the incomparable consistency of pure hand-made, makes the product have the conditions for large-scale production.

REPOSAL has invested a lot of R&D efforts in the field of crossover coil winding machines and has achieved a series of remarkable results.

In terms of winding accuracy, through in-depth research and optimization of the wiring mechanism and control system, REPOSAL's divider coil winding machine can control the winding accuracy within a very small error range. For example, for the wire with a thin wire diameter, the winding machine can accurately wind according to the set number of turns and arrangement, to ensure that the position accuracy of each turn of wire reaches ±0.05 mm, which greatly improves the quality and performance stability of the coil, and makes the crossover more accurate in the audio signal processing.

In terms of improving winding efficiency, REPOSAL has developed a unique high-speed winding technology. Thanks to the use of an advanced motor drive system and an efficient drive, the winding speed of the winding machine is increased by 30% compared to conventional models. At the same time, combined with the intelligent control system, continuous and uninterrupted winding can be realized, which greatly shortens the winding time of a single coil. For example, a common divider coil that used to take about 10 minutes to be wound by hand, but only 3 to 4 minutes with REPOSAL's winding machine significantly improved production efficiency and provided strong support for large-scale production.

In terms of versatility, REPOSAL's crossover coil winders are highly adaptable. By designing replaceable winding dies and flexible parameter adjustment functions, it is possible to wind a wide range of divider coils with different specifications, shapes and parameter requirements. Whether it's a crossover coil for a miniaturized audio device or a crossover coil for a large professional audio system, high-quality winding can be achieved on the same winding machine. For example, for coil skeletons with different inner diameters, outer diameters and height requirements, the winding machine can quickly switch production modes through simple mold change and parameter setting to meet diverse market needs.

In addition, REPOSAL also pays attention to the research on the convenience and intelligence of the winding machine. A concise and easy-to-understand human-computer interface has been developed, so that operators can master the operation method with only simple training. At the same time, the winding machine also has intelligent fault diagnosis and early warning function, which can monitor the parameters in the winding process in real time, and once there is an abnormal situation, such as wire breakage, abnormal winding tension, etc., it will immediately send out an alarm and prompt the cause of the failure, which is convenient for the operator to deal with in time and reduce the risk of production interruption and equipment damage.

Suzhou REPOSAL Electronic Mechanical Equipment Co., Ltd. is a technology enterprise specializing in R&D and production of winding equipment. For many years, it has insisted on maintaining innovation and researching and developing products with independent intellectual property rights.

　 For quite a long time, my country's winding machine manufacturing industry generally has the problems of low technology, small scale, free and scattered production, and insufficient technological innovation of most enterprises. Compared with related industries abroad, my country currently has fewer types of winding machines and supporting equipment. The control technology used is relatively backward, and its accuracy and performance are not as good as those of their European and American counterparts. Moreover, the product has low production capacity and poor stability.

     In the face of technical gaps, Suzhou REPOSAL made a detailed market research and took the entire series of precision winding machines and Roche coil winding machines as breakthrough points.It valued cooperation with user companies and not only carefully understood the existing process requirements of customers. And through the company's accumulated technical database for many years, on the premise of no or little increase in costs, it actively provides new ideas and new solutions for customer process upgrades.In a specific single implementation case, this approach has undoubtedly aggravated us The execution cost of the company has reduced the company's profits, but this idea has been implemented and verified for a long time.In fact, our customers have tapped the potential of the coil winding process through our winding machine equipment and become our long-term cooperative customers. We have also accumulated more technical data for our research and development direction and solutions through proactive improvement of individual cases, so as to achieve continuous innovation.

           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.

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.

      REPOSAL ® winding machine wire guided missile fiber winding forming technology has made a new breakthrough

           Fiber optic guidance of wire-guided missile is a closed-loop guidance and control of controlled missile by bidirectional transmission of information and control signals between missile and launcher using special fiber optics.

           The winding and release technology of optical fiber is a key technology of optical fiber guidance. At present, we have not realized automatic production in the production of optical fiber winding in our country, so we rely on the winding technical personnel's proficiency very high. The cross-turns working procedure of the winding process is still mainly manual operation, low production efficiency, high error probability and low consistency.

           In addition to other ways to solve the high speed release of optical fiber, an important way is to ensure the smooth release of optical fiber through optical fiber winding. Optical fiber winding technology is the requirement of the pointer to the optical fiber guided missile and the technology of winding the optical fiber on the spool. In view of the unique properties of optical fiber and the special use of optical fiber guided missile, optical fiber winding becomes a complicated technical problem. In the process of automatic winding, the technical difficulties related to the properties of optical fiber are as follows:

Although R type transformer is widely used, but in fact the production of manufacturers are not many, the reason is limited by the R-Core transformer winding machine, so far, there are many R-Core transformer winding machine is the principle of manual wiring, so its winding production efficiency is relatively low, Up to now, many factories are using manual winding in the winding of R-shaped transformers.

　　　Compared with mechanical gyroscopes, fiber optic gyroscopes have no moving parts, impact resistance, high sensitivity, and long life. Therefore, fiber optic gyroscopes are widely used in high-precision and high-speed positioning scenarios and will gradually replace electromechanical gyroscopes.

　　　The basic components of the fiber optic gyroscope are the optical path and the circuit, and the fiber is the core component of the gyroscope. The fiber winding machine for preparing high-precision fiber coils has also become the key point of the gyroscope.

　　　By optimizing the aforementioned tension control factors and winding accuracy algorithm, the effective and stable control of reasonable tension, the effective and reliable high-precision winding control, the memory of all process parameters, and the convenience of control, a new generation of optical fiber winding machine was developed and put into production .

　　　With the practical application of research and development results, we will continue to improve and produce high-reliability and high-efficiency fiber optic gyro winding machines.

        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.

         REPOSAL Winding Machine® Released  Tandem flat-wound winding machine         

         On August 7, Suzhou REPOSAL Electronic Machinery Equipment Co., Ltd. successfully developed a long strip product packaging tape machine.

         This equipment is mainly used to wrap insulating tape for strip products, such as long strip ferrite wrapping tape. For long strip products because of the difficult process, artificial wrapping tape is usually used. Ferrite is more brittle due to its nature. It is difficult to automate the processing, and the Xiepu winding machine overcomes the key points of a variety of processes and successfully developed a long strip product wrapping tape machine, which has been put into commercial use.

          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.
