      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.

           Fiber optic guidance belongs to the wire guidance of remote control guidance, its advantages are not only high precision, strong anti-interference ability, can be equipped with optical cable shaft, micro camera, missile launch tail will release fiber, can control the missile and obtain target information.

           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:

           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.

    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.

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.

         REPOSAL Winding Machine® Released  Tandem flat-wound winding machine         

　　　          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.

             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.
