      Precision Flexible Roche Coil Winding Machine is a special equipment for winding precision flexible Roche coils. With the actual project as the background, Xiepu successfully developed a precision flexible Rogowski coil winding machine by decomposing the flexible Rogowski coil winding process.

     The precision flexible Roche coil winding machine does not belong to the ranks of general numerical control equipment, but a special non-standard equipment. For this type of equipment, it is mainly reflected in a special purpose. Since the special purpose means that the market demand is not large, it is indispensable. For equipment manufacturers, the development of such special equipment is not favored, and cost control is very difficult.

At the same time, if you want to control the pitch accuracy and alignment, the equipment research and development costs are relatively high, and the market risk is large. At the same time, for equipment users, their corresponding The supporting equipment and instruments are a large investment.

      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:

         Since these polarized wire grids, which are wound by precision winding machines, have no underlying substrate, they have the advantage that they are not affected by substrate related dispersion and absorption, and there is no beam deviation during transmission. This provides a thin, compact and versatile polarization element with a high degree of polarization over a wide transmission range.

         At present, because there is no professional winding machine, most of the polarization grid used in our country is imported polarization grid, and the price is expensive; However, the domestic processing method of wire grid mainly uses manual winding, which has low precision and long production cycle. At the same time, the winding machine at home and abroad is mainly used in electronic components, sensors, etc., the control variable is relatively single, and the main control mode is tight layout, even the high precision winding machine, there are few equal spacing layout for the polarization line grid, so the accuracy can not meet its needs. Therefore, it is very important for the coiler to overcome the polarization grid precision winding technology.

           The main components of scanning electron microscope are electron optics system, signal collection and processing system, vacuum system, image processing display and recording system, power system and computer control system. The core part is the electron optical system, which is mainly composed of electron gun, electromagnetic condenser, diaphragm, scanning system, astigator, objective lens and various centering coils.

           Reposal® winding machine As a professional supplier of precision winding solutions, we focus on the electromagnetic condenser, objective and astigmatic, because the main components are enamoured wire windings, and the precision and consistency of the windings are highly related to the image quality of the scanning electron microscope.

          Electromagnetic lens coil.

           The electromagnetic lens is mainly used to restrain the electron beam and it can be regarded as a convex lens in optics. Because the electron beam in a rotating symmetric magnetic field will be subjected to the Lorentz force, resulting in a focusing effect. Therefore, the quality of the enamelled wire winding coil that can generate this rotationally symmetric rather than uniform magnetic field and make the electron beam focus imaging is very important.

           The enamelled wire winding coil in the magnetic lens, when the current passes through the coil, the pole shoe is magnetized, and a magnetic field is established in the heart cavity, producing a focusing effect on the electron beam. There are two kinds of enamelled wire winding in the magnetic lens, namely, the enamelled wire winding of the condenser and the enamelled wire winding of the objective lens. The lens near the electron gun is the enamelled wire winding of the condenser, while the one near the sample is the enamelled wire winding of the objective lens. General condenser is the high excitation lens enamelled wire winding, high excitation lens enamelled wire winding has many turns, a cylindrical multi-layer arrangement, requires good rotation symmetry

            In particular, the non-magnetic material in the magnetic liquid will be subjected to a magnetic field force in the non-uniform magnetic field, which makes many magnetic liquid acceleration sensors can be designed based on this characteristic.

            These characteristics make the magnetic liquid acceleration sensor has many advantages compared with the traditional acceleration sensor, such as no wear, high sensitivity and simple structure.

            However, most of the existing magnetic liquid acceleration sensors use solid mass blocks as non-magnetic substances, and use coils to detect changes in inductance under different accelerations to obtain output signals. However, its disadvantage is that it leads to complex magnetic circuit and poor sensor stability.

            A new solution emerged -- the capillary magnetic liquid acceleration sensor, good stability, simple magnetic circuit, accurate and reliable measurement results and long service life.

             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.
