After storing enough wire, the wire is cut manually, and then the wire is pulled manually to hang the wire into the groove of the side slider. After the winding starts, no matter if the wire is broken, thrown, or the number of turns is inaccurate during the winding process, the machine will not stop. After the winding is completed, the hand wheel is manually turned to turn the ring mouth of the wire storage ring to the appropriate position, and then the handle is pulled to open the ring.

[0053] The present invention provides a toroidal coil winding device. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0054] The toroidal coil winding device of the preferred embodiment of the present invention is also referred to Figures 1 to 15As shown, it includes: a workbench A, a main winding mechanism B fixed on the workbench A and provided with a wire storage ring B1, an open-loop mechanism C arranged on the left side of the main winding mechanism B for opening or closing the wire storage ring B1, a magnetic core loading mechanism D, a magnetic core rotating mechanism G, and a magnetic core unloading mechanism H arranged on the front side of the main winding mechanism B, a wire feeding mechanism E arranged on the rear side of the main winding mechanism B, and a wire cutting mechanism F arranged on the right side of the main winding mechanism B for cutting the enameled wire (not shown in the figure). Among them, the magnetic core rotating mechanism G reciprocates the magnetic core O during the process of winding the magnetic core, so that the enameled wire can be wound on a specific position of the magnetic core O, ensuring the normal winding of the magnetic core; the magnetic core loading mechanism D and the magnetic core unloading mechanism H can load and unload the magnetic core O after the open-loop mechanism C opens the wire storage ring B1; the wire feeding mechanism E is used to hook the enameled wire onto the wire storage ring B1 to assist the wire storage ring B1 in wire storage.

[0055] The main winding mechanism B further includes a main winding mounting plate B3, a plurality of wire storage ring driving wheels B2 that are against the inner side of the wire storage ring B1 and are used to drive the wire storage ring B1 to rotate, and a wire storage ring driving motor (not shown in the figure) that is used to drive the wire storage ring driving wheel B2 to rotate. The wire storage ring driving motor is connected to the wire storage ring driving wheel B2 through the cooperation of the belt gear assembly. The wire storage ring driving motor, the plurality of wire storage ring driving wheels B2 and the belt gear assembly are all arranged on the main winding mounting plate B3. The wire storage ring B1 can be driven to rotate by driving the wire storage ring driving wheel B2 to rotate through the wire storage ring driving motor B3, thereby realizing the wire storage of the wire storage ring B1 and the coil (enameled wire) of the magnetic core O.

[0056] Please refer to Fig.15 The wire storage ring B1 includes a wire storage groove B11, a wire hooking groove B12 arranged on one side of the wire storage groove B11, and a side slider B13 slidably arranged on the other side of the wire storage groove B11, and a wire clamping groove B131 is arranged on the side slider B13.

[0057] The annular coil winding equipment can realize the loading of the magnetic core O and the unloading of the magnetic core O after winding through the cooperation of the magnetic core loading mechanism D, the open-loop mechanism C, and the magnetic core unloading mechanism H; the enameled wire can be hooked onto the wire storage ring B1 through the wire feeding mechanism E, and the wire storage of the wire storage ring B1 can be completed in cooperation with the main winding mechanism B, and then the wire cutting mechanism F can be used to cut the enameled wire to facilitate the winding of the next magnetic core O; wherein, the loading and unloading of the magnetic core O, the storage of the enameled wire and the winding of the magnetic core O are all completed by the annular coil winding equipment, which has high production efficiency and effectively reduces the labor intensity of workers.

[0058] Among them, there is no need to limit the specific installation positions of the open-loop mechanism C, the core loading mechanism D, the core rotating mechanism G, the core unloading mechanism H, the wire feeding mechanism E, and the wire cutting mechanism F. It is only necessary to arrange the open-loop mechanism C, the core loading mechanism D, the core rotating mechanism G, the core unloading mechanism H, the wire feeding mechanism E, and the wire cutting mechanism F around the main winding mechanism B to facilitate the loading and unloading of the core and the loading and unloading of the enameled wire.

[0059] For further information, please refer to Figure 1 , Figure 2 The annular coil winding equipment also includes: an cycloid mechanism I for clamping the enameled wire and swinging with the rotation of the magnetic core O, an enameled wire height adjustment mechanism J for adjusting the position of the enameled wire on the magnetic core O, a magnetic core feeding mechanism K for feeding the magnetic core O, a waste wire processing mechanism L for cutting and removing the enameled wire remaining in the wire storage ring B1 after winding is completed, a wire package storage mechanism M for storing and placing the wound magnetic core O, and a control system N for controlling the annular coil winding equipment to wind the coil; wherein, the cycloid mechanism I is arranged above the front side of the wire storage ring B1, the magnetic core feeding mechanism K is arranged on the side of the magnetic core loading mechanism D, the waste wire processing mechanism L is arranged on the side of the wire storage ring B1, and the wire package storage mechanism M is arranged on the side of the magnetic core unloading mechanism H.

[0060] The control system N is respectively connected to the main winding mechanism B, the open-loop mechanism C, the magnetic core feeding mechanism D, the magnetic core rotating mechanism G, the magnetic core unloading mechanism H, the wire feeding mechanism E, the wire cutting mechanism F, the cycloid mechanism I, the enameled wire height adjustment mechanism J, the magnetic core feeding mechanism K, the waste wire processing mechanism L, and the wire package storage mechanism M. By adding the control system N to control the coil of the toroidal coil winding equipment to wind the magnetic core, the production efficiency can be effectively improved. At the same time, the actions of each mechanism of the toroidal coil winding equipment can be adjusted according to the actual production situation to ensure the normal winding of the magnetic core O.

[0061] By adding the cycloid mechanism I, the enameled wire height adjustment mechanism J, the magnetic core feeding mechanism K, the waste wire processing mechanism L, and the wire package storage mechanism M, the degree of automation of the annular coil winding equipment can be further improved. After satisfying the basic winding function, it can also be used for feeding the magnetic core O, storing the magnetic core O after winding, processing the waste wire after winding, and adjusting the position of the enameled wire on the magnetic core O when the magnetic core O is wound.

[0062] In this embodiment, the cycloid mechanism I and the enameled wire height adjustment mechanism J are respectively applied to different magnetic core winding methods, specifically:

[0063] The workflow using cycloid mechanism I is as follows:

[0064] Loading: The open-loop mechanism C opens the wire storage ring B1 of the main winding mechanism B; the core loading mechanism D grabs the core O on the core feeding mechanism K and places it on the wire storage ring B1, and then the core rotating mechanism G clamps and fixes the core O, and then the open-loop mechanism C closes the wire storage ring B1;

[0065] Wire storage: the wire feeding mechanism E hooks the enameled wire onto the wire storage ring B1, and the main winding mechanism B drives the wire storage ring B1 to rotate to store the wire;

[0066] Wire cutting: The cycloidal mechanism I hooks up and clamps the enameled wire connecting the wire feeding mechanism E and the wire storage ring B1, and then the wire cutting mechanism F cuts the enameled wire on one side of the wire feeding mechanism E;

[0067] Magnetic core winding; the wire storage ring B1 loosens the wire (the wire storage ring B1 rotates in the opposite direction), and the enameled wire is wound onto the magnetic core O under the action of the wire storage ring B1 and the side slider B13. While winding the magnetic core O, the magnetic core rotating mechanism G drives the magnetic core O to rotate back and forth to adjust the position of the enameled wire on the magnetic core O, and the cycloid mechanism I drives the enameled wire to rotate with the magnetic core O to prevent the enameled wire from being torn off when the magnetic core O rotates;

[0068] Waste wire processing: after winding is completed, the waste wire processing mechanism L separates the waste wire connected to the magnetic core O and remaining on the wire storage ring B1;

[0069] Unloading: the open-loop mechanism C opens the wire storage ring B1 of the main winding mechanism B, and the core unloading mechanism H grabs the wound core O to the wire package storage mechanism M to complete the unloading.

[0070] The working process of using the enameled wire height adjustment mechanism J is as follows:

[0071] The working process of using the enameled wire height adjustment mechanism J is basically the same as the working process of using the cycloid mechanism I, except that when winding the magnetic core O, the cycloid mechanism I is not used, but the height of the enameled wire on the magnetic core O is adjusted by the enameled wire height adjustment mechanism J; the wire cutting step is performed after the winding is completed.

[0072] The annular coil winding device is provided with two mechanisms for adjusting the position of the enameled wire, and can be applicable to two different magnetic core winding methods, thereby effectively improving the versatility of the annular coil winding device.

[0073] For further information, please refer to Figure 1 , Figure 3, the open-loop mechanism C includes an open-loop guide wheel C1 for opening the wire storage ring B1, a ring-lifting device C2 connected to the open-loop guide wheel C1 and used to drive the open-loop guide wheel C1 to pull open the wire storage ring B1, and a side-pushing device C3 connected to the ring-lifting device C2 and used to drive the open-loop guide wheel C1 to drive the pulled-open part of the wire storage ring B1 to shift to one side. Among them, the open-loop guide wheel C1 can be driven by the ring-lifting device C2 to pull open the wire storage ring, and then the open-loop guide wheel C1 can be driven by the side-pushing device C3 to shift the pulled-open part of the wire storage ring B1 to one side, so that the wire storage ring B1 can be opened, which is convenient and quick. Opening the wire storage ring B1 from the side can ensure that the wire storage ring B1 has a longer service life (compared to directly pulling it open, the deformation amount of the side shift is smaller and the service life is longer). In other embodiments, the wire storage ring B1 can be directly pulled open by the action of the ring-lifting device C2 and the open-loop guide wheel C1, which has the characteristics of simple structure and high production efficiency.

[0074] Among them, the open-loop mechanism C is installed on the main winding mounting plate B3; the ring-lifting device C2 and the side-pushing device C3 are both stroke-adjustable cylinders; by adopting the stroke-adjustable cylinder, it can be used to adjust the pulling and side-pushing stroke of the wire storage ring B1, and on the premise of ensuring that the wire storage ring B1 can be opened normally to load and unload the magnetic core 0, the deformation of the wire storage ring B1 can be reduced as much as possible, thereby increasing the service life of the wire storage ring B1.

[0075] Furthermore, the open-loop mechanism C also includes a slider rail assembly for guiding the movement direction of the ring-lifting device C2 and the open-loop guide wheel C1, which can improve the working stability of the open-loop mechanism C.

[0076] Furthermore, the open-loop guide wheel C1 is rotatably connected to the ring-lifting device C2 via a double bearing (not shown in the figure), and an anti-skid groove C11 is provided on the open-loop guide wheel C1 to prevent the wire storage ring from slipping. By providing a double bearing for rotational connection, the connection strength between the open-loop guide wheel C1 and the ring-lifting device C2 can be improved, thereby increasing the service life of the open-loop guide wheel C1; by providing the anti-skid groove C11, slipping between the wire storage ring B1 and the open-loop guide wheel C1 can be prevented during the open-loop or closed-loop process, thereby ensuring the normal operation of the open-loop or closed-loop process.

[0077] For further information, please refer to Figure 1 , Figure 4The magnetic core feeding mechanism D includes a first magnetic core clamp D1 for grabbing the magnetic core O, a first magnetic core clamp telescopic driving device D2 connected to the first magnetic core clamp D1 and used for driving the first magnetic core clamp D1 to extend or retract, a first magnetic core clamp lifting device D3 connected to the first magnetic core clamp telescopic driving device D2 and used for driving the first magnetic core clamp D1 to reciprocate up and down, a first magnetic core clamp rotating device D4 connected to the first magnetic core clamp lifting device D3 and used for driving the first magnetic core clamp D1 to reciprocate in a horizontal plane, and a stopper D5 and a stopper cylinder D6 for cooperating to stop the first magnetic core clamp D1 at the wire storage ring B1 during the rotation process in the horizontal plane.

[0078] Among them, the opening method of the wire storage ring B1 is staggered to one side, that is, the upper part B14 and the lower part B15 of the wire storage ring B1 in the open state are staggered, and the magnetic core loading mechanism D of this embodiment is located on the same side as the upper part B14 of the wire storage ring B1. When the magnetic core loading mechanism D is loading, it is necessary to avoid the upper part B14 of the wire storage ring B1, and then place the magnetic core O into the lower part B15 of the wire storage ring B1.

[0079] Specifically, the loading process of the magnetic core loading mechanism D of this embodiment is: first, the magnetic core O is grabbed by the first magnetic core clamp D1, the first magnetic core clamp telescopic driving device D2 drives the magnetic core O to retract (avoiding the storage coil B1 and other mechanisms), the first magnetic core clamp rotating device D4 rotates to adjust the position of the magnetic core O to the right side of the storage wire ring B1, the first magnetic core clamp telescopic driving device D2 drives the magnetic core O to extend, the block cylinder D6 extends, the first magnetic core clamp rotating device D4 drives the magnetic core O to move to the left, under the action of the block D5 and the block cylinder D6, the magnetic core O stops above the lower half B15 of the storage wire ring B1, and finally the first magnetic core clamp lifting device D3 drives the magnetic core O to descend to complete the loading;

[0080] The resetting process of the magnetic core feeding mechanism D is as follows: the first magnetic core jaw lifting device D3 drives the first magnetic core jaw D1 to rise, so that the first magnetic core jaw D1 leaves the lower half B15 of the wire storage ring B1, and then the first magnetic core jaw rotating device D4 drives the first magnetic core jaw D1 to move rightward, the first magnetic core jaw telescopic driving device D2 retracts, and the first magnetic core jaw rotating device D4 drives the first magnetic core jaw to move leftward back to the position of clamping the magnetic core O.

[0081] By cooperating with the block D5, the block cylinder D6, the first magnetic core clamp rotating device D4, and the first magnetic core clamp telescopic drive device D2, it is possible to avoid the upper half B14 of the wire storage ring B1 and realize loading. Among them, the two-stage formation of the first magnetic core clamp rotating device D4 can be realized by cooperating with the block D5 and the block cylinder D6, which has the characteristics of simple structure, small size and low production cost. Among them, the first magnetic core clamp D1 is a clamp cylinder, the first magnetic core clamp telescopic drive device D2 and the first magnetic core clamp lifting device D3 are both linear cylinders, and the first magnetic core clamp rotating device D4 is a rotary cylinder. In another embodiment, by setting two mutually connected rotary drive devices (not shown in the figure), the function of loading the magnetic core O with two-stage travel in cooperation with the first magnetic core clamp telescopic drive device D2 can also be realized.

[0082] For further information, please refer to Figure 1 , Figure 5 , the magnetic core unloading mechanism H includes a second magnetic core clamp H1 for grabbing the magnetic core O, a second magnetic core clamp telescopic driving device H2 connected to the second magnetic core clamp H1 and used to drive the second magnetic core clamp H1 to extend or retract, and a second magnetic core clamp lifting device H3 connected to the second clamp telescopic driving device H2 and used to drive the second magnetic core clamp H1 to reciprocate up and down, and a second magnetic core clamp rotating device H4 connected to the second magnetic core clamp lifting device H3 and used to drive the second magnetic core clamp H1 to reciprocate in a horizontal plane. In this embodiment, the structure of the magnetic core unloading mechanism H is roughly the same as that of the magnetic core loading mechanism D, but because the magnetic core unloading mechanism H and the lower half B15 of the wire storage ring B1 are located on the same side of the wire storage ring B1, the magnetic core unloading mechanism H does not need to be provided with a block D5 and a block cylinder D6 to avoid the upper half B14 of the wire storage ring B1, and the position of the magnetic core O can be adjusted directly through the second magnetic core clamp rotating device H4. In another embodiment, the positions of the upper part B14 and the lower part B15 of the wire storage ring B1 can be adjusted, and the structures of the magnetic core unloading mechanism H and the magnetic core loading mechanism D can be adjusted accordingly, so as to ensure the normal loading and unloading of the magnetic core O.

Among them, the connecting rod driving cylinder G22 drives the connecting rod assembly G21 to move, which can drive the three clamping wheels G1 to approach each other to clamp the magnetic core O, and then the clamping wheel driving motor G32, the clamping driving wheel G31, and the universal joint can drive the clamping wheel G1 to rotate, thereby driving the magnetic core O to reciprocate during the winding process.

The swinging assembly I4 includes a cycloid cylinder I41 and a swinging plate I42; the wire lifting device I2 is fixed on the swinging plate I42 and swings with the swinging plate I42.

[0089] The wire lifting device I2 can drive the wire hooking block I1 to move upward to hook the enameled wire until the wire hooking block I1 moves to cooperate with the clamping block I3 to clamp and fix the enameled wire. At this time, the wire cutting mechanism F cuts off the enameled wire connected to the wire feeding mechanism E. When storing the wire, the swing plate I42 is driven to rotate by the cycloidal cylinder I41 to drive the enameled wire to rotate with the rotation of the magnetic core O.

[0090] Furthermore, the wire hooking block I1 is provided with a wire lifting groove I11 for hooking the enameled wire. By adding the wire lifting groove I11, the stability of the wire lifting can be improved, and the enameled wire can be effectively prevented from sliding off the wire hooking block I1 during the wire lifting process.

[0091] Furthermore, the enameled wire height adjustment mechanism J comprises: a wire hanging rod J1 tilted upwardly and used to hang the enameled wire, and a rotating lifting device J2 connected to the wire hanging rod J1 and used to drive the wire hanging rod J1 to rotate and hang the wire and drive the wire hanging rod J1 to move up and down. The enameled wire can be hooked on the wire hanging rod J1 by driving the wire hanging rod J1 to rotate through the rotating lifting device J2, and then the wire hanging rod J1 can be driven up and down by the rotating lifting device J2 to adjust the position of the enameled wire on the magnetic core O, which is convenient and quick.

[0092] Furthermore, the coil storage mechanism M includes a material placement plate M1 for placing coil products (completely wound magnetic cores O), a guide post M2 disposed on the material placement plate M1 and used to limit the position of the coil products, and an elastic buffer M3 sleeved on the lower part of the guide post M2 for providing buffering for the falling coil products. By arranging the guide post M2 on the material placement plate M1, it can be used to guide the falling direction of the coil products, so that the coil products can be neatly stacked together without the need for workers to do additional sorting, effectively reducing the labor intensity of workers; by arranging the elastic buffer M3 under the guide post M2, it can provide buffering for the falling coil products, reduce the bumping of the coil products, and thus improve the yield rate of the coil products.

[0093] Among them, the elastic buffer M3 is a compression spring, and the coil storage mechanism M also includes a buffer rubber pad M5 arranged on the upper end of the compression spring. This embodiment adopts a compression spring, which has the characteristics of low production cost and long service life, but the compression spring itself has a large hardness and is easy to collide and rub with the coil product. By adding the buffer rubber pad M5, the probability of damage to the coil product can be effectively reduced. In another embodiment, the elastic buffer M3 can also be an elastic sponge pad, which can also achieve the buffering function.

[0094] Preferably, the guide posts M2 and elastic buffers M3 are arranged in rows with multiple groups at intervals, and the wire package storage mechanism M also includes a material placement plate translation assembly M4 for driving the material placement plate M1 to translate and adjust the position of the guide posts M2. By setting multiple groups of guide posts M2, the storage capacity of the wire package storage mechanism M can be effectively increased; and then the position of the guide posts M2 can be adjusted by the material placement plate translation assembly M4, and the guide posts M2 can be moved to the unloading position to ensure the normal unloading of the coil products. Among them, the material placement plate translation assembly M4 is composed of a rotating motor, a gear, and a rack meshing with the gear, and the material placement plate M1 is fixedly connected to the rack. By driving the gear to rotate through the rotating motor, the rack meshing with the gear can be driven to reciprocate, thereby realizing the movement of the material placement plate M1.

[0095] Furthermore, the waste wire processing mechanism L includes a wire hooking rod L1 having a wire hooking boss L11 at one end and used to pull the enameled wire, a wire hooking rod translation driving device L2 connected to the wire hooking rod L1 and used to drive the wire hooking rod L1 to translate, a clamping member L3 fixedly arranged on the wire hooking rod translation driving device L2 and used to cooperate with the wire hooking boss L11 to clamp the enameled wire, and a wire cutting device L4 arranged on one side of the wire hooking rod translation driving device L2 and used to cut the enameled wire. The wire hooking rod translation driving device L2 can drive the wire hooking rod L1 having a wire hooking boss L11 at one end to enter the wire storage ring B1 to hook the enameled wire, and then the wire hooking rod translation driving device L2 drives the wire hooking rod L1 to pull back and clamp the enameled wire under the cooperation of the wire hooking boss L11 and the clamping member L3, and finally the waste wire can be separated from the enameled wire on the product through the wire cutting device L4, and the entire waste wire removal action is completed mechanically, which effectively improves production efficiency and reduces the labor intensity of workers.

[0096] Furthermore, the waste wire processing mechanism L also includes a wire hooking rod lifting device L5 for driving the wire hooking rod translation driving device L2 to move up and down, and a wire blowing pipe L6 arranged on one side of the wire cutting device L4; the wire blowing pipe L6 is connected to an air pump (not shown in the figure). The wire hooking rod lifting device L5 can be used to move the position of the waste wire processing mechanism L up and down, so that the waste wire processing mechanism L is completely lowered to the inside of the workbench A, effectively preventing the waste wire processing mechanism L from affecting the normal operation of its mechanism during the non-waste wire processing steps, making the structure more compact; the wire blowing pipe L6 can be used to blow away the waste wire on the wire hooking rod L1, preventing the waste wire from remaining on the wire hooking rod L1, and ensuring the normal removal of the waste wire.

[0097] The thread hooking rod L1 is cylindrical, and the thread hooking boss L11 is provided with a rubber pad (not shown in the figure) for cooperating with the clamping member. By setting the thread hooking rod L1 to be cylindrical, its surface is relatively smooth, and after the thread trimming is completed, it is convenient for the waste thread to be separated from the thread hooking rod L1. By providing the rubber pad, the clamping force between the thread hooking boss L11 and the clamping member L3 can be effectively improved, ensuring that the thread trimming and separation action is carried out normally.

[0098] Furthermore, the wire feeding mechanism E includes: a wire grabbing assembly E1 for grabbing and fixing the end of the enameled wire, a wire moving assembly E2 for supplying the enameled wire and adjusting the position of the wire supply, and a side slider positioning assembly E3 for positioning the side slider B13 on the wire storage ring B1. Through the cooperation of the wire grabbing assembly E1, the wire moving assembly E2, the side slider positioning assembly E3 and the wire storage ring B1, the enameled wire can be hooked onto the wire storage ring B1 for wire storage, which is convenient and quick, and effectively improves production efficiency.

[0099] Further, the wire grabbing assembly E1 includes: a wire grabbing cylinder E11 for grabbing the enameled wire, and a wire pulling cylinder E12 for moving the wire grabbing cylinder E11;

[0100] The wire moving assembly E2 comprises: a moving plate E21, a first wire moving cylinder E22 for driving the moving plate E21 to move, a second wire moving cylinder E23, a third wire moving cylinder E24 and a wire raising cylinder E25 which are connected in sequence to the moving plate E21, a wire conveying tube E26 which is fixedly connected to the output rod of the wire raising cylinder E25, and an enameled wire driving assembly E27 which drives the enameled wire to extend out of the wire conveying tube E26;

[0101] The side slider positioning assembly E3 includes: a blocking rod E31 for blocking the movement of the side slider, and a side slider blocking cylinder E32 for driving the blocking rod E31 to extend or retract.

[0102] Furthermore, the enameled wire driving assembly E27 includes a driving mounting plate E271, a driving wheel E272 rotatably arranged on the driving mounting plate E271, a driven wheel E273 that cooperates with the driving wheel E272 to drive the enameled wire to move, an enameled wire driving motor E274 for driving the driving wheel E272 to rotate, and a driven wheel driving cylinder E275 that drives the driven wheel E273 to approach or move away from the driving wheel E272.

[0103] The initial state of the wire pulling cylinder E12 is the retracted state; the initial states of the first wire moving cylinder E22, the second wire moving cylinder E23, and the third wire moving cylinder E24 are the extended states; the initial state of the wire raising cylinder E25 is the retracted state. In the initial state, the wire grabbing cylinder E11 is located on the side (left side) of the wire storage ring B1 close to the wire hooking groove B12, and the side slider positioning assembly E27 and the wire conveying tube E26 are located on the side (right side) of the side slider B13.

[0104] The working process of the wire feeding mechanism E is as follows:

[0105] The wire storage ring hooks and stores the wire: the first wire moving cylinder E22, the second wire moving cylinder E23, and the third wire moving cylinder E24 all contract, driving the wire conveying tube E26 to the left side of the wire hooking groove B12 of the wire storage ring B1; the driven wheel driving cylinder E275 drives the driven wheel E273 to approach the driving wheel E272 and press the enameled wire, and the enameled wire driving motor E274 drives the driving wheel E272 to rotate so that the enameled wire moves and extends out of the wire conveying tube E26; the wire grabbing cylinder E11 grabs the extended enameled wire and pulls the enameled wire downward under the action of the wire pulling cylinder E12, and then the first wire moving cylinder E22 extends to move the wire conveying tube E26 to the top of the wire storage groove B11, and at this time, the wire storage ring B1 is rotated to hook the enameled wire through the wire hooking groove, and the wire storage can be carried out by continuing to rotate;

[0106] Side slider wire clamping: After completing wire storage, the side slider blocking cylinder E272 drives the blocking rod E271 to extend, so that the side slider B13 stops at a specific position of the wire storage ring B1, the second wire moving cylinder E23 extends, and the wire feeding cylinder E25 extends, so that the enameled wire is hooked onto the wire clamping groove B131 of the side slider B13, and finally the first wire moving cylinder E22 extends to adjust the position of the wire conveying tube E26 to one side of the wire cutting mechanism F.
