Description

Technical Field

[0001] This invention relates to the field of electromagnetic coil processing equipment technology, and specifically to a devarnishing and winding device for electromagnetic coil processing. Background Technology

[0002] Square coils are widely used in electronic components such as relays and inductors due to their excellent space utilization. However, their automated manufacturing process, especially the winding stage, has always been a challenge for the industry.

[0003] Existing winding equipment generally uses a winding method with continuous spindle rotation. This method is very efficient for round coils, but it is not suitable for the geometric characteristics of square coils. The continuous rotation trajectory is fundamentally contradictory to the 90° right-angle bending process required for square coils, resulting in coils with indistinct edges, irregular shapes, and poor consistency after forming.

[0004] Therefore, there is a lack of existing technology for a dedicated device that can fundamentally change the winding motion principle to adapt to the bending and forming of shape coils. Summary of the Invention

[0005] The purpose of this application is to provide an enamel stripping and winding device for electromagnetic coil processing, which can realize segmented bending of enameled wire during the winding process, ensuring the sharpness of the edges and the consistency of the shape of the square coil, effectively solving the industry problem of automated preparation of square coils, and significantly improving product consistency and production efficiency.

[0006] The technical solution adopted in this invention is: an enamel stripping and winding device for processing electromagnetic coils, comprising a feeding mechanism, an enamel stripping mechanism, a feeding mechanism, a winding mechanism, and a shearing mechanism arranged in sequence;

[0007] The feeding mechanism is used to continuously supply enameled wire;

[0008] The paint stripping mechanism is used to strip paint from the pre-set paint stripping sections of the enameled wire supplied by the feeding mechanism.

[0009] The feeding mechanism is used to transport the stripped enameled wire to the winding mechanism;

[0010] The winding mechanism is used to wind the enameled wire fed by the feeding mechanism. It includes a winding fixing frame, a winding post fixed on the winding fixing frame, a bending winding block rotatably disposed on one side of the winding post, and a driving component. The winding fixing frame is provided with a receiving station and a bending winding station. The bending winding block is provided with a winding groove. The driving component is used to drive the bending winding block to reciprocate multiple times around the winding post between the receiving station and the bending winding station. When the bending winding block rotates to the receiving station, the winding groove aligns with the feeding mechanism to receive the enameled wire. When the bending winding block rotates to the bending winding station, the bending winding block drives the enameled wire to bend around the winding post at a preset angle. Through multiple reciprocating rotations, the enameled wire is bent into an electromagnetic coil segment by segment.

[0011] The shearing mechanism is used to cut the enameled wire after winding is completed.

[0012] Optionally, the winding mechanism further includes a winding opening provided on the winding fixing frame and a feeding channel provided on the winding fixing frame. The winding post is located inside the winding opening, the side wall of the bending winding block abuts against the inner wall of the winding opening, and one end of the feeding channel faces the feeding mechanism, while the other end extends into the winding opening.

[0013] When the bending and winding block rotates to the receiving station, the enameled wire conveyed by the feeding mechanism enters the winding groove through the feeding channel, with one side of the enameled wire in the width direction located in the winding groove and the other side located on the top surface of the winding column.

[0014] Optionally, the winding mechanism further includes a wire pressing assembly, which is used to press the enameled wire firmly onto the winding post during winding;

[0015] The wire pressing assembly includes a wire pressing head that can be raised and lowered on the top of the winding post, and a drive structure for driving the wire pressing head to rise and fall.

[0016] Optionally, the varnish stripping and winding equipment further includes a coil guiding mechanism, including a guide that can be raised and lowered above the electromagnetic coil. The guide is used to constrain the coil as the number of turns of the electromagnetic coil increases, so as to prevent the upper layer of coil turns from shifting.

[0017] Optionally, the drive assembly includes a gear disk rotatably mounted on a winding fixing frame, a transmission gear meshing with the gear disk, and a drive motor for driving the transmission gear to rotate, wherein the bottom side of the bending winding block is fixedly connected to the gear disk.

[0018] Optionally, the feeding mechanism includes a feeding assembly disposed between the paint stripping mechanism and the winding mechanism. The feeding assembly includes a feeding fixing frame slidably disposed between the paint stripping mechanism and the winding mechanism, a first clamping block fixedly disposed on the feeding fixing frame, a second clamping block that can be raised and lowered above the first clamping block, a feeding cylinder for driving the second clamping block to rise and fall vertically relative to the first clamping block, and a feeding drive component. The first clamping block and the second clamping block cooperate to form a clamping gap for the enameled wire to pass through.

[0019] The feeding cylinder is used to drive the second clamping block to descend and cooperate with the first clamping block to clamp or release the enameled wire located in the clamping gap. The feeding drive is used to drive the feeding fixing frame to move back and forth between the paint stripping mechanism and the winding mechanism.

[0020] Optionally, the feeding mechanism further includes two sets of pressing components disposed between the paint stripping mechanism and the winding mechanism, with the two sets of pressing components located on both sides of the feeding mechanism;

[0021] The pressing assembly includes a pressing frame, a first pressing block fixed on the pressing frame, a second pressing block that can be lifted and lowered on the first pressing block, and a pressing cylinder for driving the second pressing block to lift and lower. The first pressing block and the second pressing block cooperate to form a pressing gap for the enameled wire to pass through. The second pressing block is used to cooperate with the first pressing block to press or release the enameled wire.

[0022] Optionally, the feeding mechanism includes a feeding frame, a feeding roller rotatably mounted on the feeding frame, and a feeding guide wheel rotatably mounted above the feeding roller. The enameled wire is wound on the feeding roller, and its free end passes upward around the feeding guide wheel and then sequentially passes through the paint stripping mechanism, the feeding mechanism, and the winding mechanism.

[0023] Optionally, a positioning mechanism is further provided between the feeding mechanism and the stripping mechanism, including a horizontal positioning component for positioning the enameled wire in the horizontal direction and a vertical positioning component for positioning the enameled wire in the vertical direction.

[0024] Optionally, the paint stripping mechanism includes a paint stripping box, a paint stripping fixing plate disposed in the paint stripping box, a first paint stripping positioning block and a second paint stripping positioning block symmetrically disposed on the paint stripping fixing plate, and two sets of laser paint stripping components symmetrically disposed on the upper and lower sides of the paint stripping box. The upper and lower sides of the paint stripping box are both open, and the two sides of the paint stripping box are respectively provided with a feed port and a discharge port.

[0025] The first and second paint stripping positioning blocks cooperate to form a paint stripping channel for the enameled wire to pass through;

[0026] The top of the paint stripping fixing plate is provided with a paint stripping cover plate for covering the paint stripping channel. The paint stripping cover plate and the bottom side of the paint stripping fixing plate are provided with paint stripping openings corresponding to the position of the paint stripping channel, so that the laser emitted by the laser paint stripping component can strip the paint from the enameled wire passing through the paint stripping channel.

[0027] After adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0028] This application provides a stripping and winding device for electromagnetic coil processing, comprising a feeding mechanism, a stripping mechanism, a feeding mechanism, a winding mechanism, and a shearing mechanism arranged sequentially. During operation, the feeding mechanism continuously supplies enameled wire. The stripping mechanism strips the enameled wire from a predetermined stripping section of the wire supplied by the feeding mechanism. The feeding mechanism conveys the stripped enameled wire to the winding mechanism. Subsequently, the winding mechanism's drive assembly drives a bending and winding block to reciprocate between a receiving station and a bending and winding station. At the receiving station, the bending and winding block receives the enameled wire fed by the feeding mechanism. At the bending and winding station, it bends the enameled wire around a winding post at a predetermined angle (90°). This process is repeated, causing the enameled wire to bend segment by segment into an electromagnetic coil (square coil). Finally, after the square coil is wound, the shearing mechanism cuts the enameled wire, completing the fabrication of the entire electromagnetic coil. Compared with existing technologies, this application, through the cooperation between the drive component, the bending and winding block, and the winding post, can realize the segmented bending of the enameled wire during the winding process, ensuring the sharpness of the edges and the consistency of the shape of the square coil, effectively solving the industry problem of automated manufacturing of square coils, and significantly improving product consistency and production efficiency.

[0055] The following will refer to the appendices in the embodiments of the present invention. Figures 1-16The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

[0056] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0057] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, if the word "and / or" appears throughout the text, it means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0058] This embodiment provides a stripping and winding device for processing electromagnetic coils, referring to... Figure 1 and Figure 2 The device includes a feeding mechanism 10, a stripping mechanism 20, a feeding mechanism 30, a winding mechanism 40, and a cutting mechanism 50 arranged sequentially. The feeding mechanism 30 is used to continuously supply enameled wire 100. The stripping mechanism 20 is used to strip the enameled wire 100 supplied by the feeding mechanism 10 from a preset stripping part. The feeding mechanism 30 is used to transport the stripped enameled wire 100 to the winding mechanism 40. The winding mechanism 40 is used to wind the enameled wire 100 transported by the feeding mechanism 30. The cutting mechanism 50 is used to cut the enameled wire 100 after winding.

[0059] It should be noted that the electromagnetic coil 200 processed in this embodiment is a square coil or a rectangular coil. Through the cooperation between the feeding mechanism 10, the paint stripping mechanism 20, the feeding mechanism 30, the winding mechanism 40 and the shearing mechanism 50, a fully automated processing flow from feeding, paint stripping, feeding, winding and shearing is realized.

[0060] Furthermore, referring to Figure 2 and Figure 3 The feeding mechanism 10 includes a feeding frame 11, a feeding roller 12 rotatably mounted on the feeding frame 11, and a feeding guide wheel 13 rotatably mounted above the feeding roller 12. The enameled wire 100 is wound on the feeding roller 12, and its free end passes upward around the feeding guide wheel 13 and then passes through the paint stripping mechanism 20, the feeding mechanism 30, and the winding mechanism 40 in sequence.

[0061] The feeding roller 12 can rotate stably on the feeding frame 11, thereby providing basic power for the continuous supply of enameled wire 100 and ensuring that the enameled wire 100 can be smoothly unwound from the feeding roller 12. The feeding guide wheel 13 can accurately guide the direction of the enameled wire 100, so that the enameled wire 100 winds upward along a predetermined path, avoiding problems such as tangling and deviation of the enameled wire 100 during transmission, and ensuring that the enameled wire 100 can pass through the paint stripping mechanism 20, the feeding mechanism 30 and the winding mechanism 40 in sequence and accurately, thereby realizing the stable and orderly progress of the entire processing flow.

[0062] In addition, to achieve stable material supply, the feeding frame 11 is also equipped with a feeding drive component 14 for driving the feeding roller 12 to rotate. The feeding drive component 14 includes a feeding shaft 141, a feeding motor 142, a feeding gearbox 143, a first feeding gear 144 fixedly mounted on the output shaft of the feeding gearbox 143, and a second feeding gear 145 fixedly mounted on one end of the feeding shaft 141. The feeding roller is rotatably connected to the feeding frame 11 through the feeding shaft 141, and the output shaft of the feeding motor 142 is fixedly connected to the feeding gearbox 143. During feeding, the feeding motor 142 starts, and its output shaft drives the feeding gearbox 143 to rotate. The feeding gearbox 143 meshes with the second feeding gear 145 fixed on one end of the feeding shaft 141 through the first feeding gear 144 on the output shaft, thereby driving the feeding shaft 141 to rotate. Since the feeding roller 12 is rotatably connected to the feeding frame 11 through the feeding shaft 141, the feeding roller 12 rotates accordingly, so that the enameled wire 100 wound on the feeding roller 12 can be continuously and stably unwound. Meanwhile, the feeding guide wheel 13 precisely guides the unwound enameled wire 100, allowing its free end to pass upwards around the feeding guide wheel 13 and then accurately pass through the stripping mechanism 20, the feeding mechanism 30, and the winding mechanism 40 in sequence. This provides a stable and continuous supply of enameled wire 100 for subsequent processing steps such as stripping, feeding, winding, and cutting, ensuring that the entire stripping and winding equipment for processing electromagnetic coils 200 can operate efficiently and orderly, thereby guaranteeing the processing quality and production efficiency of square coils.

[0063] Furthermore, referring to Figure 2 , Figure 5 , Figure 6 and Figure 7The paint stripping mechanism 20 includes a paint stripping box 21, a paint stripping fixing plate 22 disposed inside the paint stripping box 21, a first paint stripping positioning block 23 and a second paint stripping positioning block 24 symmetrically disposed on the paint stripping fixing plate 22, and two sets of laser paint stripping components 25 symmetrically disposed on the upper and lower sides of the paint stripping box 21. The upper and lower sides of the paint stripping box 21 are both open, and the two sides of the paint stripping box 21 are respectively provided with a feed port 211 and a discharge port 212. The first paint stripping positioning block 23 and the second paint stripping positioning block 24 cooperate to form a paint stripping channel for the enameled wire 100 to pass through. The top of the paint stripping fixing plate 22 is provided with a paint stripping cover plate 26 for covering the paint stripping channel. The paint stripping cover plate 26 and the bottom side of the paint stripping fixing plate 22 are provided with paint stripping openings 261 corresponding to the position of the paint stripping channel, so that the laser emitted by the laser paint stripping component 25 can strip the enameled wire 100 passing through the paint stripping channel.

[0064] During operation, the enameled wire 100 supplied by the feeding mechanism 10 enters the stripping box 21 through the inlet 211 and then exits through the stripping channel from the outlet 212. During this process, two sets of laser stripping components 25, symmetrically arranged on the upper and lower sides of the stripping box 21, work simultaneously. The lasers emitted by these components pass through the stripping cover plate 26 and the stripping fixing plate 22, which have stripping openings 261 corresponding to the stripping channel positions, precisely irradiating the enameled wire 100 passing through the stripping channel. This efficiently and accurately strips the predetermined stripping areas of the enameled wire 100. Because laser stripping has advantages such as concentrated energy, fast stripping speed, and high stripping precision, it ensures that the insulating varnish layer is completely removed from the stripping areas of the enameled wire 100 without damaging other parts of the wire, thus providing a reliable quality enameled wire 100 for subsequent winding operations. After the enameled wire 100 has undergone the stripping process, it will be sent out from the discharge port 212 of the stripping box 21 and enter the feeding mechanism 30. The feeding mechanism 30 will accurately transport it to the winding mechanism 40 for winding operation.

[0065] It should be noted that the laser stripping assembly 25 is a conventional technique in the field, typically comprising a laser generator, an optical focusing system, and a corresponding control module. The laser generator produces a laser beam of specific wavelength and power, while the optical focusing system focuses the laser beam into a small spot to increase the laser's energy density, enabling more effective removal of the insulating varnish layer from the surface of the enameled wire 100. The control module is responsible for precisely controlling parameters such as the laser generator's output power and pulse frequency to ensure the stability and consistency of the stripping process. In practical applications, the parameters of the laser stripping assembly 25 can be flexibly adjusted according to factors such as the material and specifications of the enameled wire 100 and the stripping requirements to achieve the best stripping effect.

[0066] In this embodiment, refer to Figure 6 and Figure 8The paint stripping mechanism 20 also includes an adjustment component 27 for adjusting the vertical height between the laser paint stripping component 25 and the paint stripping box 21. The adjustment component 27 includes an adjustment bracket 271, an adjustment screw 272 rotatably mounted on the adjustment bracket 271, a handwheel 273 on the top of the adjustment screw 272, a nut seat 274 threadedly connected to the adjustment screw 272, and a lifting seat 275 fixedly connected to the nut seat 274. The laser paint stripping component 25 is fixedly mounted on the lifting seat 275. By rotating the handwheel 273, the adjustment screw 272 is rotated, causing the nut seat 274 and the lifting seat 275 to rise and fall vertically relative to the adjustment bracket 271, thereby causing the laser paint stripping component 25 to rise and fall vertically relative to the adjustment bracket 271, thus realizing the adjustment of the vertical height between the laser paint stripping component 25 and the paint stripping box 21.

[0067] In addition, the paint stripping mechanism 20 also includes an exhaust gas collection assembly 28, which is used to collect the exhaust gas generated during the paint stripping process. The exhaust gas collection assembly 28 includes an exhaust gas collection pipe 281 and an exhaust gas treatment box 282. The exhaust gas treatment box 282 is located below the paint stripping box 21. One end of the exhaust gas collection pipe 281 is located inside the paint stripping box 21, and the other end extends downward into the exhaust gas treatment box 282.

[0068] Furthermore, referring to Figure 2 and Figure 4 A positioning mechanism 60 is provided between the feeding mechanism 10 and the paint stripping mechanism 20. The positioning mechanism 60 includes a horizontal positioning component 61 for positioning the enameled wire 100 in the horizontal direction and a vertical positioning component 62 for positioning the enameled wire 100 in the vertical direction.

[0069] By configuring the horizontal positioning component 61 and the vertical positioning component 62 of the positioning mechanism 60, the enameled wire 100 can be precisely positioned from all directions before entering the stripping mechanism 20. The horizontal positioning component 61 ensures that the enameled wire 100 is in the correct horizontal position, preventing lateral deviation. The vertical positioning component 62 positions the enameled wire 100 vertically, preventing vertical movement or positional deviation during transmission. This ensures that the enameled wire 100 enters the stripping mechanism 20 in a stable and accurate state, providing a solid guarantee for the accuracy and effectiveness of subsequent stripping processing. In this way, after positioning, the enameled wire 100 is precisely within the working range of the laser stripping component 25 when entering the stripping mechanism 20, ensuring accurate stripping and improving the processing precision and product quality of the entire stripping and winding equipment.

[0070] In some specific embodiments, the horizontal positioning assembly 61 includes a horizontal positioning frame 611, a horizontal positioning fixing plate 612 fixed on the horizontal positioning frame 611, a horizontal positioning sliding plate 613 slidably disposed on the horizontal positioning frame 611 and located on one side of the horizontal positioning fixing plate 612, a plurality of horizontal positioning wheels 614 disposed on the horizontal positioning fixing plate 612 and the horizontal positioning sliding plate 613, and a horizontal positioning cylinder 615 for driving the horizontal positioning sliding plate 613 to move toward or away from the horizontal positioning fixing plate 612. The plurality of horizontal positioning wheels 614 are evenly disposed on the horizontal positioning fixing plate 612 and the horizontal positioning sliding plate 613 along the conveying direction of the enameled wire 100. The horizontal positioning wheels 614 on the horizontal positioning fixing plate 612 and the horizontal positioning wheels 614 on the horizontal positioning sliding plate 613 cooperate to form a horizontal positioning channel for the enameled wire 100 to pass through.

[0071] During operation, the horizontal positioning cylinder 615 drives the horizontal positioning sliding plate 613 to move closer to the horizontal positioning fixed plate 612, causing the horizontal positioning wheels 614 on the horizontal positioning fixed plate 612 and the horizontal positioning wheels 614 on the horizontal positioning sliding plate 613 to move closer to each other, thereby confining the enameled wire 100 within the horizontal positioning channel formed by their cooperation. In this process, multiple horizontally evenly arranged horizontal positioning wheels 614 can support and position the enameled wire 100 from different positions, ensuring that the enameled wire 100 does not shift left or right in the horizontal direction and always remains on the correct conveying path, preparing it for accurate entry into the subsequent paint stripping mechanism 20.

[0072] In some specific embodiments, the vertical positioning assembly 62 includes a vertical positioning frame 621, a vertical positioning fixing plate 622 fixed on the vertical positioning frame 621, a vertical positioning lifting plate 623 that is vertically movable above the vertical positioning fixing plate 622 and opposite to the vertical positioning fixing plate 622, vertical positioning wheels 624 disposed on the vertical positioning fixing plate 622 and the vertical positioning lifting plate 623, and a vertical positioning cylinder 625 for driving the vertical positioning lifting plate 623 to vertically lift relative to the vertical positioning fixing plate 622. A plurality of vertical positioning wheels 624 are evenly disposed on the vertical positioning fixing plate 622 and the vertical positioning lifting plate 623 along the conveying direction of the enameled wire 100, and the vertical positioning wheels 624 on the vertical positioning fixing plate 622 and the vertical positioning lifting plate 623 cooperate to form a vertical positioning channel for the enameled wire 100 to pass through.

[0073] During operation, the vertical positioning lifting plate 623, driven by the vertical positioning cylinder 625, descends towards the vertical positioning fixed plate 622, causing the vertical positioning wheels 624 on the vertical positioning fixed plate 622 and the vertical positioning lifting plate 623 to approach each other, thereby confining the enameled wire 100 within the vertical positioning channel formed by their cooperation. During this process, the multiple vertical positioning wheels 624 on the vertical positioning fixed plate 622 and the multiple vertical positioning wheels 624 on the vertical positioning lifting plate 623 work together to support and position the enameled wire 100, ensuring that the enameled wire 100 does not shift vertically and remains at a stable conveying height. Working in conjunction with the horizontal positioning component 61, this allows the enameled wire 100 to accurately enter the paint stripping mechanism 20.

[0074] Furthermore, referring to Figure 2 , Figure 5 and Figure 9 The feeding mechanism 30 includes a feeding assembly 31 disposed between the paint stripping mechanism 20 and the winding mechanism 40. The feeding assembly 31 includes a feeding fixing frame 311 slidably disposed between the paint stripping mechanism 20 and the winding mechanism 40, a first clamping block 312 fixedly disposed on the feeding fixing frame 311, a second clamping block 313 movable above the first clamping block 312, a feeding cylinder 314 for driving the second clamping block 313 to move vertically relative to the first clamping block 312, and a feeding drive component 3. 15, wherein the first clamping block 312 and the second clamping block 313 cooperate to form a clamping gap for the enameled wire 100 to pass through, the feeding cylinder 314 is used to drive the second clamping block 313 to descend and cooperate with the first clamping block 312 to clamp or release the enameled wire 100 located in the clamping gap, and the feeding drive 315 is used to drive the feeding fixing frame 311 to move back and forth between the stripping mechanism 20 and the winding mechanism 40 to intermittently feed the enameled wire 100 to the winding mechanism 40.

[0075] During operation, the enameled wire 100 supplied by the feeding mechanism 10 is first manually guided through the positioning mechanism 60, the paint stripping mechanism 20, the feeding mechanism 30, and the winding mechanism 40. Then, the feeding cylinder 314 drives the second clamping block 313 to descend and cooperate with the first clamping block 312 to clamp the enameled wire 100 passing through the clamping gap. At this time, the feeding drive 315 drives the feeding fixing frame 311 to move closer to the winding mechanism 40, thereby conveying a section of enameled wire 100 to the winding mechanism 40. After conveying a section of enameled wire 100 to the winding mechanism 40, the feeding cylinder 314 drives the second clamping block 313 to rise, causing the second clamping block 313 to separate from the first clamping block 312. Then, the feeding drive 315 drives the feeding fixing frame 311 to move to the initial position to prepare for the next conveying.

[0076] It should be noted that the amount of enameled wire 100 fed by the feeding mechanism 30 to the winding mechanism 40 and the bending angle of the enameled wire 100 can be changed by adjusting the moving distance of the feeding drive component 315 driving the feeding fixed frame 311 and the rotation angle of the bending and winding block 43, thereby enabling the winding mechanism 40 to complete electromagnetic coils 200 of different shapes.

[0077] Furthermore, the feeding mechanism 30 also includes two sets of pressing components 32 disposed between the paint stripping mechanism 20 and the winding mechanism 40, with the two sets of pressing components 32 located on both sides of the feeding mechanism 30 respectively;

[0078] The pressing assembly 32 includes a pressing frame 321, a first pressing block 322 fixed on the pressing frame 321, a second pressing block 323 that can be lifted and lowered on the first pressing block 322, and a pressing cylinder 324 for driving the second pressing block 323 to lift and lower. The first pressing block 322 and the second pressing block 323 cooperate to form a pressing gap for the enameled wire 100 to pass through. The second pressing block 323 is used to cooperate with the first pressing block 322 to press or release the enameled wire 100.

[0079] Through the above settings, after the feeding assembly 31 completes one feeding cycle, when the winding mechanism 40 bends the enameled wire 100, the first pressing block 322 and the second pressing block 323 of the two sets of pressing assemblies 32 cooperate to press the enameled wire 100 tightly, preventing it from moving horizontally. This ensures the consistency of the length of the enameled wire 100 delivered by the feeding assembly 30 to the winding mechanism 40, providing a reliable guarantee for the winding mechanism 40 to complete high-quality square or rectangular coil winding operations. Furthermore, when the winding mechanism 40 completes the bending and prepares to deliver the next section of enameled wire 100, the pressing cylinder 324 drives the second pressing block 323 to rise, causing the second pressing block 323 to separate from the first pressing block 322, releasing the pressed enameled wire 100. This allows the feeding assembly 31 to smoothly deliver the next section of enameled wire 100 to the winding mechanism 40 for subsequent winding operations.

[0080] Furthermore, in this embodiment, the feeding drive 315 is a lead screw motor drive structure. In other embodiments, the feeding drive 315 may also be a linear motor or a cylinder drive structure, which will not be limited here.

[0081] Furthermore, referring to Figure 2 , Figure 10 , Figure 11 and Figure 12The winding mechanism 40 includes a winding fixing frame 41, a winding post 42 fixedly mounted on the winding fixing frame 41, a bending winding block 43 rotatably mounted on one side of the winding post 42, and a drive assembly 44. The winding fixing frame 41 is provided with a receiving station 411 and a bending winding station 412. The bending winding block 43 is provided with a winding groove 431. The drive assembly 44 is used to drive the bending winding block 43 to move around the winding post 42 at the receiving station 411 and the bending winding station 412. The bending and winding block 43 rotates repeatedly between positions 412. When the bending and winding block 43 rotates to the receiving position 411, the winding groove 431 aligns with the feeding mechanism 30 to receive the enameled wire 100. When the bending and winding block 43 rotates to the bending and winding position 412, the bending and winding block 43 drives the enameled wire 100 to bend around the winding post 42 at a preset angle. Through repeated reciprocating rotations, the enameled wire 100 is bent into electromagnetic coil 200 segment by segment.

[0082] When the bending and winding block 43 is in the receiving station 411, the feeding mechanism 30 delivers a preset length of enameled wire 100 into the winding groove 431 of the bending and winding block 43. Then, the drive assembly 44 drives the bending and winding block 43 to rotate to the bending and winding station 412, bending the enameled wire 100 in the winding groove 431 around the bending post at a preset angle (90° in this embodiment). Then, the drive assembly 44 drives the bending and winding block 43 to return to the receiving station 412. 11. The feeding mechanism 30 then feeds a preset length of enameled wire 100 into the winding groove 431 of the bending and winding block 43. The driving component 44 drives the bending and winding block 43 to rotate to the bending and winding station 412 again, bending the enameled wire 100 again. This process is repeated. By driving the bending and winding block 43 to rotate repeatedly through the driving component 44, the enameled wire 100 fed by the feeding mechanism 30 into the winding groove 431 is bent into electromagnetic coils 200 segment by segment.

[0083] Furthermore, the winding mechanism 40 also includes a winding opening 413 opened on the winding fixing frame 41 and a feeding channel 414 provided on the winding fixing frame 41. The winding post 42 is located inside the winding opening 413. The side wall of the bending winding block 43 abuts against the inner wall of the winding opening 413 to guide the bending winding block 43 when the driving assembly 44 drives the bending winding block 43 to rotate, so as to ensure the stability of the rotation of the bending winding block 43. One end of the feeding channel 414 faces the feeding mechanism 30, and the other end extends into the winding opening 413. When the bending winding block 43 rotates to the receiving station 411, the enameled wire 100 conveyed by the feeding mechanism 30 enters the winding groove 431 through the feeding channel 414, and one side of the width of the enameled wire 100 is located in the winding groove 431, and the other side is located on the top surface of the winding post 42.

[0084] Understandably, when the enameled wire 100 supplied by the manually guided feeding mechanism 10 passes through the positioning mechanism 60, the paint stripping mechanism 20, the feeding mechanism 30 and the winding mechanism 40 in sequence, the enameled wire 100 is guided into the feeding channel 414. Then, the feeding mechanism 30 conveys a certain length of enameled wire 100 to the feeding mechanism 10 into the winding groove 431 of the bending and winding block 43. The driving component 44 drives the bending and winding block 43 to rotate to the bending and winding station 412, thereby completing the bending of the enameled wire 100.

[0085] Furthermore, referring to Figure 11 , Figure 13 and Figure 14 The winding mechanism 40 also includes a wire pressing assembly 45, which is used to press the enameled wire 100 onto the winding post 42 during winding. The wire pressing assembly 45 includes a wire pressing head 451 that can be raised and lowered on the top of the winding post 42 and a drive structure for driving the wire pressing head 451 to rise and fall.

[0086] During operation, the drive structure first drives the pressing head 451 to rise relative to the winding post 42, making way for the feeding of the enameled wire 100. This allows the feeding mechanism 30 to smoothly feed the enameled wire 100 into the winding groove 431 of the bending and winding block 43. When the feeding mechanism 30 feeds a certain length of enameled wire 100 into the winding groove 431, the drive structure drives the pressing head 451 to descend and press the enameled wire 100 onto the winding post 42. This ensures that when the drive assembly 44 drives the bending and winding block 43 to rotate and bend the enameled wire 100, the enameled wire 100 is less likely to shift or deviate, thus ensuring the stability and accuracy of the winding process. Each time the bending and winding block 43 bends the enameled wire 100, the pressing head 451 keeps the enameled wire 100 pressed firmly against the winding post 42 until the winding of that section of enameled wire 100 is completed. Then, the drive structure drives the pressing head 451 to rise, preparing for the conveying and winding of the next section of enameled wire 100. By setting up the pressing assembly 45, the displacement and offset of the enameled wire 100 caused by force or vibration during the winding process are effectively avoided, greatly improving the winding quality of the electromagnetic coil 200.

[0087] In some specific embodiments, the driving structure includes a pressing rod 452 that is vertically inserted into the winding post 42 and fixedly connected to the bottom side of the pressing head 451; a connecting rod 453 with one end fixed to the bottom end of the pressing rod 452 and the middle hinged to the winding fixing frame 41; and a lifting cylinder 454 for driving the end of the connecting rod 453 away from the pressing rod 452 to rise vertically. When the feeding mechanism 30 delivers a certain length of enameled wire 100 into the winding groove 431, the lifting cylinder 454 drives the end of the connecting rod 453 away from the pressing rod 452 to rise vertically, causing the other end of the connecting rod 453 to fall vertically, thereby causing the pressing rod 452 and the pressing head 451 to fall vertically, so that the pressing head 451 can press the enameled wire 100 delivered by the feeding mechanism 30 onto the winding post 42.

[0088] Furthermore, the drive assembly 44 includes a gear disk 441 rotatably mounted on the winding fixing frame 41, a transmission gear 442 meshing with the gear disk 441, and a drive motor 443 for driving the transmission gear 442 to rotate. The bottom side of the bending winding block 43 is fixedly connected to the gear disk 441.

[0089] During operation, the drive motor 443 drives the transmission gear 442 to rotate, which in turn drives the gear disk 441 to rotate, causing the bending and winding block 43 to rotate. This allows the bending and winding block 43 to reciprocate between the receiving station 411 and the bending and winding station 412, enabling the bending and winding block 43 to bend the enameled wire 100 into electromagnetic coils 200 segment by segment.

[0090] Furthermore, the varnish stripping and winding equipment provided in this embodiment also includes a coil guiding mechanism 70, including a guide member 71 that can be lifted and lowered above the electromagnetic coil 200. The bottom end of the guide member 71 extends into the electromagnetic coil 200 and abuts against the inner wall of the electromagnetic coil 200, which is used to constrain the coil when the number of turns of the electromagnetic coil 200 increases, so as to prevent the upper layer of coils from shifting.

[0091] It should be noted that, due to the large number of turns in the electromagnetic coil 200, the upper layers of turns are prone to displacement during the winding process, resulting in poor coil forming quality and even potential coil scattering. This application addresses this issue by providing a coil guiding mechanism 70, whose guide 71 is vertically and flexibly positioned above the electromagnetic coil 200. During the winding process, as the number of turns increases, the guide 71 can appropriately constrain the coil, ensuring that each layer of turns is accurately positioned, effectively preventing displacement of the upper layers and significantly improving the winding accuracy and forming quality of the electromagnetic coil 200.

[0092] In some specific embodiments, the coil guiding mechanism 70 further includes a coil guiding bracket 72, a coil guiding cylinder 73 fixedly mounted on the coil guiding bracket 72, and a coil guiding rod 74. One end of the coil guiding rod 74 is fixedly connected to the piston rod of the coil guiding cylinder 73, and the other end extends directly above the electromagnetic coil 200. One end of the guide member 71 is fixed to the end of the coil guiding rod 74 that extends directly above the electromagnetic coil 200, and the other end extends vertically downward into the electromagnetic coil 200 and abuts against the inner wall of the electromagnetic coil 200.

[0093] When the number of turns of the electromagnetic coil 200 increases to a certain level, the coil guide cylinder 73 drives the coil guide rod 74 to descend vertically, causing the bottom end of the guide 71 to extend into the electromagnetic coil 200 and abut against the inner wall of the electromagnetic coil 200. At this time, the guide 71 can play a good guiding and constraining role on the upper layer of coils, effectively avoiding the problem of coil scattering caused by the displacement of the upper layer of coils of the electromagnetic coil 200. This results in the electromagnetic coil 200 being tightly structured, with distinct layers, high precision, and good forming quality, meeting the high requirements for the processing of the electromagnetic coil 200.

[0094] In this embodiment, the guide 71 is a flexible wire, and to prevent the guide 71 from damaging the electromagnetic coil 200, the outer surface of the part of the guide 71 that extends into the electromagnetic coil 200 is covered with a protective film.

[0095] Furthermore, referring to Figure 15 and Figure 16 The shearing mechanism 50 includes a shearing slide frame 51 slidably disposed on the side of the winding mechanism 40 away from the feeding mechanism 30, a pneumatic shear assembly 52 fixedly disposed on the shearing slide frame 51, and a shearing cylinder 53 for driving the shearing slide frame 51 to move. The shearing slide frame 51 is provided with a shearing groove 511, and the shearing part of the pneumatic shear assembly 52 is located in the shearing groove 511.

[0096] In this embodiment, a feeding platform 80 is provided on the side of the shearing mechanism 50 away from the winding mechanism 40. After the winding of the electromagnetic coil 200 is completed, the driving component 44 of the winding mechanism 40 drives the bending winding block 43 to rotate to the receiving station 411, so that the feeding mechanism 30 can smoothly transport the enameled wire 100 into the winding groove 431 of the bending winding block 43. Then the feeding mechanism 30 continues to transport the enameled wire 100, so that the completed electromagnetic coil 200 at least partially abuts against the feeding platform 80 after passing the shearing sliding frame 51 of the shearing mechanism 50. At this time, the shearing cylinder 53 of the shearing mechanism 50 drives the shearing sliding frame 51 to move, so that the enameled wire 100 at the tail of the electromagnetic coil 200 is located in the shearing groove 511. Then the air shearing component 52 cuts the enameled wire 100 at the tail of the electromagnetic coil 200.

[0097] Working Principle: During operation, the feeding mechanism 10 first provides enameled wire 100, which is then manually guided through the positioning mechanism 60, the paint stripping mechanism 20, the feeding mechanism 30, and the winding mechanism 40. The positioning mechanism 60 uses its horizontal positioning component 61 and vertical positioning component 62 to position the enameled wire 100 horizontally and vertically, respectively, ensuring accurate conveying path. The paint stripping mechanism 20 removes the paint layer from the surface of the enameled wire 100. The feeding mechanism 30, through the cooperation of the feeding component 31 and the pressing component 32, intermittently feeds a preset length of enameled wire 100 to the winding mechanism 40, ensuring consistent conveying length. Driven by the drive assembly 44, the bending and winding block 43 of the winding mechanism 40 reciprocates between the receiving station 411 and the bending and winding station 412, bending the enameled wire 100 fed by the feeding mechanism 30 into electromagnetic coils 200 segment by segment. Simultaneously, the wire pressing assembly 45 presses the enameled wire 100 firmly onto the winding post 42 during the winding process to prevent displacement and shifting. As the number of turns of the electromagnetic coil 200 increases, the coil guiding mechanism 70 constrains and guides the coil to prevent displacement of the upper turns. After the electromagnetic coil 200 is wound, it is fed to the unloading table 80 by the feeding mechanism 30. The shearing cylinder 53 of the shearing mechanism 50 drives the shearing sliding frame 51 to move, positioning the tail of the electromagnetic coil 200 within the shearing groove 511. Then, the pneumatic shear assembly 52 cuts the enameled wire 100 at the tail end of the electromagnetic coil 200, completing the entire processing of the electromagnetic coil 200.

[0098] After the shearing mechanism 50 cuts the enameled wire 100, the cut end of the enameled wire 100 has been stripped of its enamel by the stripping mechanism 20. Then, the feeding mechanism 30 retracts the enameled wire 100 onto the winding mechanism 40. Finally, the feeding mechanism 30 and the winding mechanism 40 cooperate to perform the winding of the next electromagnetic coil 200, thereby achieving continuous and efficient production of the electromagnetic coil 200. Specifically, when the previous electromagnetic coil 200 is nearing completion of winding, the stripping mechanism 20 performs the stripping operation on the enameled wire 100 at a designated position according to a preset program. After the shearing mechanism 50 cuts the enameled wire 100, the feeding mechanism 30 precisely controls the retraction distance of the enameled wire 100, positioning it within the feeding channel 414 of the winding mechanism 40, ensuring that the winding of the new coil can begin from the accurate position.

[0099] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
