Description

Technical Field

[0001] This invention relates to the field of coil winding technology, and more particularly to a coil winding device. Background Technology

[0002] In the production of inductor coils, the insulation coating on the enameled wire ends needs to be stripped, wound, and the wire ends bent and shaped. The degree of automation of the winding equipment, the quality of wire end processing, and the cleanliness of the production process directly determine the electrical performance and batch yield of the coil. Currently, winding often uses multi-process separate equipment, which has a low degree of automation and requires a lot of manual intervention, resulting in poor coil processing accuracy and low quality. Although fully automated integrated winding equipment has emerged in the industry, it still has some shortcomings. For example, a winding device disclosed in patent publication number CN110676049A integrates an unwinding mechanism, a shaping mechanism, a stripping mechanism, a wire threading assembly, a bending assembly, and a coil winding mechanism along the wire conveying path. This device realizes automatic feeding, straightening and shaping, mechanical stripping, wire end bending, coil winding, and automatic unloading of enameled wire, solving the problems of manual winding, low automation, a lot of manual intervention, and poor processing accuracy of existing equipment, and improving coil production efficiency and dimensional consistency to a certain extent. However, in actual mass production applications, there are still several shortcomings that make it difficult to adapt to the manufacturing of high-precision inductor coils, specifically in the following aspects: First, the winding clamping and wire end shaping structures lack flexibility, resulting in limited adaptability and forming quality. This patent relies solely on the groove of the winding shaft to fix the wire end, lacking an elastic clamping structure. The clamping length cannot be adaptively shortened during wire winding, leading to loose coils and inconsistent coil outer diameters. Furthermore, the coil shaping station lacks a limiting structure, causing the coil to easily rotate and shift during shaping. The bending direction of the wire end cannot be precisely constrained, resulting in poor shaping consistency.

[0003] Secondly, the lack of a dedicated structure for treating the insulation break at the wire end after mechanical stripping results in poor insulation and conductivity reliability of the product. This patented stripping mechanism uses a rotating blade to mechanically scrape off the enamel, which easily leads to enamel peeling, fine enamel flakes, and micro-cracks in the enamel at the break. This patented equipment cannot perform heat shrinkage treatment on the enamel break, and residual enamel flakes and peeling enamel adhere to the exposed copper conductor surface, easily causing incomplete soldering, fluctuations in contact resistance, and electrical malfunctions during subsequent soldering.

[0004] Finally, the lack of an automatic cleaning structure for paint scraps and debris leads to dust pollution that affects equipment operation and product quality. This patented equipment lacks a cleaning mechanism; the removed paint scraps scatter across the workbench, wire channels, and winding stations. Accumulated paint scraps can clog the wire feeding, winding, and bending mechanisms, requiring frequent shutdowns for cleaning and slowing down production. Simultaneously, fine paint scraps adhere to the wire surface and between coil winding layers, causing abnormal interlayer insulation and increased high-frequency losses, failing to meet the electrical specifications required for precision inductors.

[0005] In summary, existing fully automated integrated coil winding equipment still has a series of problems and cannot meet production needs. Summary of the Invention

[0009] Further optimization includes a horizontally arranged fourth guide block with a guide hole, an inverted second lifting cylinder above the middle of the fourth guide block, a second pressure block connected below the second lifting cylinder, a second rubber-coated block below the second pressure block, and a second clearance groove in the middle of the fourth guide block.

[0010] In a further optimization, the cutting structure includes a first horizontal cylinder, which is connected to a first gripper cylinder, and each of the two finger ends of the first gripper cylinder is connected to a cutter.

[0011] Further optimization includes a first support frame with a hand-cranked slide table on it. A mounting box is located above the hand-cranked slide table, and a paint stripping knife is located inside the mounting box. The paint stripping knife is connected to a first servo motor via a synchronous belt assembly. The mounting box has a guide hole and a felt mat is located on the side of the mounting box near the wire feeding mechanism. The mounting box is connected to a vacuum conveyor.

[0012] Further optimization involves a roller feeding mechanism, which includes a second bracket. An inverted second servo motor is mounted on the second bracket. The upper end of the second servo motor is connected to two first gears via a synchronous belt assembly. Each of the two first gears meshes with a second gear. A roller is connected to the upper end of each of the two first gears and the two second gears. A first guide block with a guide groove is provided in the middle of the four rollers. A second guide block with a guide hole is provided on the side of the four rollers near the winding and cutting mechanism.

[0013] Further optimization involves a cylinder-driven wire feeding mechanism, which includes a horizontally arranged first linear module connected to a third bracket. A third guide block with a guide hole is mounted on the third bracket. An inverted first lifting cylinder is located above the center of the third guide block. A first pressure block is connected below the first lifting cylinder. A first rubber-coated block is located below the first pressure block. A first clearance groove is located in the center of the third guide block.

[0014] Further optimization involves a shaping mechanism comprising a horizontally arranged fourth linear module. A connecting plate is positioned above the fourth linear module. An adjustable support frame is located on each side of the connecting plate. Each of the two support frames is equipped with a second horizontal cylinder.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] like Figure 1-3 and Figure 8-10As shown, this application discloses a coil winding device, including a stripping mechanism 1, a wire feeding mechanism 2, a winding and cutting mechanism 3, and a shaping mechanism 4 arranged sequentially along the conveying direction of the enameled wire. In this application, the winding device is used for the automated winding of inductor coils. The stripping mechanism 1 is used to strip the enameled wire, capable of stripping the enameled wire in segments, with the stripped portion serving as the end of the wound coil. The wire feeding mechanism 2 is used to convey the enameled wire from the stripping mechanism 1 towards the winding and cutting mechanism 3, facilitating the winding of the enameled wire by the winding and cutting mechanism 3. The winding and cutting mechanism 3 is used to wind the enameled wire and cut it after winding, completing the coil winding. The shaping mechanism 4 is used to bend the ends of the wound coil, achieving coil shaping. The entire winding device operates fully automatically, with high speed and efficiency.

[0021] In this application, the winding and cutting mechanism 3 includes a vertical plate 31, on which a wire structure 32 is provided. A winding structure 33 is located on the side of the wire structure 32 near the shaping mechanism 4, and a cutting structure 34 is located below the wire structure 32. An electron microscope 35 and a display screen 36 are also provided on the vertical plate 31. The vertical plate 31 is used for mounting the various structural components; the wire structure 32 supports and guides the enameled wire, ensuring that the enameled wire can be accurately delivered to the position of the winding structure 33; the winding structure 33 is used for winding and rotating the coil, facilitating the shaping of the coil ends; and the cutting structure 34 is used to cut the enameled wire after the coil winding is completed. The lens of the electron microscope 35 is directly facing the winding position of the winding structure 33, magnifying the working part of the winding structure 33 for easy observation of the coil winding process, which is then displayed on the display screen 36 for convenient observation and monitoring of the coil winding process.

[0022] In this application, the winding structure 33 includes a winding assembly 331 and a rotating assembly 332 arranged vertically. The winding assembly 331 is used for winding the coil, and the rotating assembly 332 serves as the base for winding the coil. It can cooperate with the winding assembly 331 to shape the winding shape of the coil and rotate the wound coil horizontally by 180°, which facilitates the shaping mechanism 4 to shape the coil ends.

[0023] In this application, the winding assembly 331 includes a second linear module 3311 arranged vertically. The second linear module 3311 is connected to an inverted third servo motor 3312. The lower end of the third servo motor 3312 is connected to a first gripper 3313. The first gripper 3313 is rotatably connected to a second gripper 3314. The second gripper 3314 is in the shape of a "7". A first spring 3315 is provided between the second gripper 3314 and the first gripper 3313. A first pressure plate 3316 is provided above the second gripper 3314. An inverted third lifting cylinder 3317 is connected above the first pressure plate 3316.

[0024] The second linear module 3311 drives the third servo motor 3312, the first gripper 3313, the second gripper 3314, the first pressure plate 3316, and the third lifting cylinder 3317 to move vertically up and down, facilitating the vertical movement during the clamping and winding of the enameled wire. The third servo motor 3312 is used for winding rotation. It drives the first gripper 3313 to rotate, which in turn drives the second gripper 3314 to rotate synchronously, thus rotating the enameled wire held by the first and second grippers 3313 and achieving the winding action. Simultaneously, the clamping positions of the first and second grippers 3313 and the output shaft of the third servo motor 3312 are eccentrically positioned to ensure the enameled wire can rotate in a circular direction, ensuring effective winding. The second clamp 3314 has a V-shaped structure with an upward protrusion on its upper surface away from the second clamp 3314. The lower end of the second clamp 3314 is rotatably connected to the lower end of the first clamp 3313. A first spring 3315 is provided between the upper part of the second clamp 3314 and the first clamp 3313. The first spring 3315 causes the lower end of the second clamp 3314 to fit together with the lower end of the first clamp 3313, forming a clamping action. The clamping structure formed by the first clamp 3313 and the second clamp 3314 driven by the first spring 3315 provides a relatively loose clamping of the enameled wire. This allows the clamped enameled wire to move relative to the first clamp 3313 and the second clamp 3314 during winding, meaning the clamped enameled wire can become shorter and shorter, thus achieving the winding of the enameled wire. A first pressure plate 3316 is provided above the second gripper 3314. The first pressure plate 3316 can be driven to descend by the third lifting cylinder 3317, which can press down on the protrusion on the second gripper 3314, causing the second gripper 3314 to rotate relative to the first gripper 3313, so that the lower ends of the first gripper 3313 and the second gripper 3314 are in an open state.

[0025] like Figure 8-10 As shown, in one embodiment of this application, in order to cooperate with the winding assembly 331, the structure of the rotating assembly 332 is as follows: the rotating assembly 332 includes a third linear module 3321 arranged vertically, the third linear module 3321 is connected to a centrally mounted fourth servo motor 3322, the upper end of the fourth servo motor 3322 is connected to a connector 3323, the connector 3323 is connected to a winding substrate 3324 that can slide vertically, the connector 3323 is provided with a second pressure plate 3325 for adjusting the height of the winding substrate 3324, the winding substrate 3324 is connected to a second spring 3326, and the second pressure plate 3325 is connected to a centrally mounted fourth lifting cylinder 3327.

[0026] In this embodiment, the third linear module 3321 is used to drive the connector 3323 and the winding substrate 3324 to rise and fall, facilitating the movement of the winding substrate 3324 to a set position during winding and adjusting the height of the coil after winding. The fourth servo motor 3322 is used to drive the connector 3323 and the winding substrate 3324 to rotate, enabling the wound coil to rotate 180°, facilitating the shaping of the coil ends by the shaping mechanism 4. The connector 3323 is used for mounting the winding substrate 3324, which serves as a reference plate for coil winding. The winding assembly 331 clamps the head of the enameled wire and rotates around the winding substrate 3324 to achieve coil winding. The fourth lifting cylinder 3327 can drive the second pressure plate 3325 to rise and fall, thereby pressing the winding substrate 3324 relative to the connector 3323 to rise and fall, thereby adjusting the length of the winding substrate 3324 extending out of the connector 3323, which facilitates coil winding and removal of the coil from the winding substrate 3324. The winding substrate 3324 is provided with two protrusions that extend from the side of the connector 3323. The connector 3323 is provided with guide grooves for the protrusions on the winding substrate 3324 to slide up and down. The second spring 3326 is sleeved on the connector 3323 and abuts against the protrusions on the winding substrate 3324, realizing the elastic installation of the winding substrate 3324 and can be used for the elastic reset of the winding substrate 3324.

[0027] like Figure 11 As shown, in another embodiment of this application, the wire structure 32 includes a horizontally arranged fourth guide block 321 with a guide hole. An inverted second lifting cylinder 322 is provided above the middle of the fourth guide block 321. A second pressing block 323 is connected below the second lifting cylinder 322. A second rubber-coated block 324 is provided below the second pressing block 323. A second clearance groove 3211 is provided in the middle of the fourth guide block 321.

[0028] In this embodiment, the fourth guide block 321 is used for guiding and supporting the enameled wire, which is achieved through the guide hole on it. The second lifting cylinder 322 can drive the second pressure block 323 to rise and fall, and drive the second rubber-coated block 324 to rise and fall synchronously. The fourth guide block 321 is provided with a second clearance groove 3211. The bottom of the second clearance groove 3211 is located in the radial height range of the guide hole. The second clearance groove 3211 is used for clearance between the second pressure block 323 and the second rubber-coated block 324 during lifting and lowering. When the second rubber-coated block 324 descends, it can press down the enameled wire guided in the guide hole of the fourth guide block 321 to prevent the enameled wire from moving. It is used to fix the enameled wire when winding the wire and to prevent the enameled wire from retracting during the transport of the wire.

[0029] like Figure 8 and Figure 10As shown, in another embodiment of this application, the cutting structure 34 includes a first horizontal cylinder 341, the first horizontal cylinder 341 is connected to a first gripper cylinder 342, and a cutter 343 is connected to each of the two finger ends of the first gripper cylinder 342.

[0030] In this embodiment, the first horizontal cylinder 341 drives the first gripper cylinder 342 to move left and right, thereby driving the cutter 343 to move left and right synchronously. After the coil is wound, the first horizontal cylinder 341 drives the first gripper cylinder 342 to move to the left to the position of the winding structure 33. Then, the first gripper cylinder 342 drives the two cutters 343 to move relative to each other to cut the enameled wire. Then, the first gripper cylinder 341 and the cutter 343 move to the right and reset under the action of the first horizontal cylinder 341.

[0031] like Figure 4 As shown, in another embodiment of this application, the paint stripping mechanism 1 includes a first bracket 11, a hand-cranked slide 12 is provided on the first bracket 11, a mounting box 13 is provided above the hand-cranked slide 12, a paint stripping knife 14 is provided inside the mounting box 13, the paint stripping knife 14 is connected to a first servo motor 15 through a synchronous belt assembly, a guide hole is provided on the mounting box 13, a wool felt 16 is provided on the side of the mounting box 13 near the wire feeding mechanism 2, and a vacuum conveyor 17 is connected to the mounting box 13.

[0032] In this embodiment, the first bracket 11 is used to install the hand-cranked slide table 12, which allows for left and right adjustment of the positions of the structural components mounted on it. The mounting box 13 is used to install the paint stripper 14, preventing paint peeling and debris from splashing. The first servo motor 15 is connected to the paint stripper 14 via a synchronous belt assembly. The rotation of the first servo motor 15 drives the paint stripper 14 to rotate, thus stripping the paint from the enameled wire. The felt 16 is used to clean the enameled wire after the paint has been stripped, preventing any peeled paint from adhering to the copper wire. The vacuum conveyor 17 generates negative pressure through a vacuum pump or vacuum generator, creating a pressure difference between the inside and outside of the pipe. This allows the paint peeling and debris inside the mounting box 13 to be drawn out and transported to the container connected to the vacuum conveyor 17, facilitating the collection of paint peeling and debris.

[0033] like Figure 1 , Figure 2 and Figure 5As shown, in another embodiment of this application, the wire feeding mechanism 2 is a roller wire feeding mechanism 21. The roller wire feeding mechanism 21 includes a second bracket 211. An inverted second servo motor 212 is provided on the second bracket 211. The upper end of the second servo motor 212 is connected to two first gears 213 through a synchronous belt assembly. The two first gears 213 are respectively meshed with a second gear 214. The upper ends of the two first gears 213 and the two second gears 214 are respectively connected to a roller 215. A first guide block 216 with a guide groove is provided in the middle of the four rollers 215. A second guide block 217 with a guide hole is provided on the side of the four rollers 215 near the winding and cutting mechanism 3.

[0034] In this embodiment, the wire feeding mechanism 2 adopts a roller-type conveying structure, specifically a roller wire feeding mechanism 21. The roller wire feeding mechanism 21 includes a second bracket 211, a second servo motor 212, a first gear 213, a second gear 214, a roller 215, a first guide block 216, and a second guide block 217. The two first gears 213 are spaced apart, and their front sides are respectively meshed with a second gear 214. Each of the two first gears 213 and the two second gears 214 is connected to a roller 215 via a rotating shaft. The four rollers 215 are arranged in a rectangular array, and the two sets of front and rear rollers 215 are in rolling contact. The enameled wire passes between the two sets of front and rear rollers 215. The second bracket 211 is used for mounting other structural components of the roller wire feeding mechanism 21. The second servo motor 212 can drive the two first gears 213 to rotate via a synchronous belt assembly. The two first gears 213 can drive the two second gears 214 to rotate synchronously, thereby realizing the rotation of the four rollers 215 and conveying the enameled wire from right to left. The first guide block 216 and the second guide block 217 are used for guiding the enameled wire. The first guide block 216 is provided with guide grooves arranged on the left and right, and the second guide block 217 is provided with guide holes arranged on the left and right for guiding the conveying of the enameled wire.

[0035] like Figure 3 , Figure 6 and Figure 7 As shown, in another embodiment of this application, the wire feeding mechanism 2 is a cylinder wire feeding mechanism 22. The cylinder wire feeding mechanism 22 includes a horizontally arranged first linear module 221. The first linear module 221 is connected to a third bracket 222. A third guide block 223 with a guide hole is installed on the third bracket 222. An inverted first lifting cylinder 224 is provided above the middle of the third guide block 223. A first pressure block 225 is connected below the first lifting cylinder 224. A first rubber-coated block 226 is provided below the first pressure block 225. A first clearance groove 2231 is provided in the middle of the third guide block 223.

[0036] Unlike the above embodiments, in this embodiment, the wire feeding mechanism 2 adopts a cylinder-type conveying method, specifically a cylinder-type wire feeding mechanism 22. The cylinder-type wire feeding mechanism 22 includes a first linear module 221, a third support 222, a third guide block 223, a first lifting cylinder 224, a first pressure block 225, and a first rubber-coated block 226. The first linear module 221 is positioned left and right, enabling it to drive the third support 222 to move left and right. The third support 222 is equipped with the third guide block 223 and the first lifting cylinder 224. The left and right movement of the third support 222 synchronously drives the third guide block 223 and the first lifting cylinder 224 to move left and right. The third guide block 223 is provided with a guide hole for the passage and guidance of the enameled wire. The third guide block 223 is provided with a first clearance groove 2231, which is connected to the third guide block. The first rubber-coated block 226 is located in the first clearance groove 2231. When the first lifting cylinder 224 drives the first pressure block 225 to descend, it can drive the first rubber-coated block 226 to descend synchronously, press down on the enameled wire, prevent the enameled wire from moving, and facilitate pulling the enameled wire to move from right to left.

[0037] Specifically, after the conductor structure 32 drives the second pressure block 323 and the second rubber-coated block 324 to press down and fix the enameled wire through the second lifting cylinder 322, the first linear module 221 drives the third support 222 to move to the right, which in turn drives the third guide block 223 to move to the right. At this time, the piston rod of the first lifting cylinder 224 is not extended. When the first linear module 221 drives the third support 222 to move to the right by a set distance and then stops moving, the first lifting cylinder 224 drives the first pressure block 225 and the first rubber-coated block 226 to descend and press down the enameled wire in the first clearance groove 2231. At this time, the conductor structure 32 no longer fixes the enameled wire. Then the first linear module 221 drives the third support 222 to move to the left, which in turn drives the first lifting cylinder 224, the first pressure block 225, the first rubber-coated block 226, and the enameled wire pressed by the first rubber-coated block 226 to move to the left, thereby realizing the fixed-distance transport of the enameled wire.

[0038] In this application, the wire feeding mechanism 2 adopts only one of the roller wire feeding mechanism 21 and the cylinder wire feeding mechanism 22.

[0039] like Figure 12-14As shown, in another embodiment of this application, the shaping mechanism 4 includes a horizontally arranged fourth linear module 41. A connecting plate 42 is provided above the fourth linear module 41. An adjustable support frame 43 is provided on each side of the connecting plate 42. A second horizontal cylinder 44 is provided on each of the two support frames 43. The two second horizontal cylinders 44 are arranged opposite to each other, and a fixed top block 45 is connected to each of their opposite sides. A second gripper cylinder 46 is provided in the middle of the connecting plate 42. A shaping block 47 is arranged vertically on each of the two finger ends of the second gripper cylinder 46. The two shaping blocks 47 are staggered and each is provided with a limiting groove 471.

[0040] In this embodiment, the first linear module 41 is arranged left and right, enabling the connecting plate 42 and other structural components mounted on it to move synchronously left and right. The support frame 43 supports the second horizontal cylinder 44 and the fixed top block 45, and the support frame 43 is equipped with a guide structure for guiding the movement of the fixed top block 45. Simultaneously, each support frame 43 is connected to two manual displacement platforms, including a front-to-back displacement platform and an up-and-down displacement platform, enabling fine-tuning of the front-to-back and up-and-down positions of the support frame 43. There are two support frames 43, symmetrically arranged on the front and back sides of the connecting plate 42. The second horizontal cylinders 44 are respectively mounted on the two support frames 43. The two second horizontal cylinders 44 can drive the two fixed top blocks 45 to move towards each other, thus fixing the coil wound by the winding and cutting mechanism 3, facilitating the second gripper cylinder 46 to drive the shaping block 47 to bend and shape the coil ends.

[0041] Specifically, there are two shaping blocks 47 arranged vertically, with the two shaping blocks 47 staggered front to back. Each shaping block 47 has a limiting groove 471 on its right end face and on its adjacent end faces, and the limiting grooves 471 on the two end faces of each shaping block 47 are connected. When the second gripper cylinder 46 drives the two shaping blocks 47 to approach each other, the two shaping blocks 47 can compress the upper and lower ends of the coil, bending them towards each other. The two limiting grooves 471 on the two shaping blocks 47 limit and guide the bending, causing the two ends of the coil to be bent upwards and downwards respectively, thus achieving the bending and shaping of the coil ends.

[0042] like Figure 15 As shown, in another embodiment of this application, a top wire assembly 5 is provided between the winding and cutting mechanism 3 and the shaping mechanism 4. The top wire assembly 5 includes a first tilting cylinder 51 that is inclined toward the winding and cutting mechanism 3, and the first tilting cylinder 51 is connected to a slidingly disposed top rod 52.

[0043] In this embodiment, the top wire assembly 5 is used to top the enameled wire, allowing the enameled wire to be pushed between the first gripper 3313 and the second gripper 3314, facilitating precise gripping of the enameled wire by the first gripper 3313 and the second gripper 3314. Specifically, the first tilting cylinder 51 drives the top rod 52 to move towards the center of the winding and cutting mechanism 3, pushing the enameled wire extending from the conductor structure 32 between the first gripper 3313 and the second gripper 3314.

[0044] like Figure 16 As shown, in another embodiment of this application, a heating component 6 is provided on one side of the winding and cutting mechanism 3. The heating component 6 includes a second tilting cylinder 61 that is tilted toward the winding structure 33. The second tilting cylinder 61 is connected to a sliding heating gun 62. The heating gun 62 is connected to a metal air pipe 63 and an air source.

[0045] In this embodiment, the heating component 6 is used to blow hot air at the junction of the bare wire and the sheath of the enameled wire, causing the enamel coating at the break point of the sheath to shrink, thus eliminating burrs, curling edges, and tiny enamel flakes, and eliminating the fine cracks on the enamel coating caused by peeling. Specifically, an air source can supply air to the heating gun 62 and the metal air pipe 63. The heating gun 62 can heat the airflow in the metal air pipe 63, making the airflow blown out of the metal air pipe 63 hot air. The second tilting cylinder 61 can drive the heating gun 62 and the metal air pipe 63 to move towards the center of the winding and cutting mechanism 3, heating the two joints of the wound coil with hot air.

[0046] In this application, the working process of the winding device is as follows: (1) The enameled wire passes through the stripping mechanism 1, the wire feeding mechanism 2 and the winding and cutting mechanism 3 in sequence via the wire feeding mechanism; (2) The enamel stripping mechanism 1 operates by driving the enamel stripping knife 14 to rotate through the first servo motor 15, thereby stripping the enamel from the enameled wire and stripping the enamel from the enameled wire in segments; at the same time, the wire feeding mechanism 2 feeds the stripped enameled wire toward the position of the winding and cutting mechanism 3, and stops feeding after each set length. (3) The winding and cutting mechanism 3 operates, fixing the enameled wire through the wire structure 32. Specifically, the second lifting cylinder 322 drives the second pressing block 323 and the second rubber-coated block 324 to descend and press the enameled wire guided in the fourth guide block 321. Then, under the action of the second straight module 3311, the winding assembly 331 moves down as a whole, and then the top wire assembly 5 pushes the end of the enameled wire into the space between the first clamp 3313 and the second clamp 3314 of the winding assembly 331. Immediately afterwards, the rotating assembly 332 rises as a whole under the action of the third straight module 3321 and rises to the set position. The position is determined, and then the third servo motor 3312 drives the first gripper 3313 and the second gripper 3314 to rotate synchronously, so that the enameled wire is wound onto the winding substrate 3324, and the end of the wound coil is facing to the right, consistent with the direction of the incoming wire of the enameled wire; then the first horizontal cylinder 341 of the cutting structure 34 drives the first gripper cylinder 342 to move to the left, and the first gripper cylinder 342 drives the two cutters 343 to cut the enameled wire; then the fourth servo motor 3322 drives the connector 3323 to rotate the winding substrate 3324 by 180°, so that the coil rotates by 180°; (4) When the shaping mechanism 4 is activated, the fourth linear module 41 drives the connecting plate 42 to move to the right. Then, the two second horizontal cylinders 44 drive the two fixed top blocks 45 to move towards each other and clamp the coil on the winding substrate 3324. Then, the second gripper cylinder 46 drives the two shaping blocks 47 to move up and down respectively, bending the two ends of the coil upward and downward respectively, so as to realize the bending and shaping of the ends of the coil and complete the shaping operation of the coil.
