Description

Technical Field

[0001] This invention belongs to the technical field of stator winding processing, specifically relating to an automatic winding device for multiple strands of flat copper wire. Background Technology

[0002] The stator windings of motors generally adopt a flat copper wire structure. Flat copper wire has advantages such as high slot fill factor, low copper loss, and excellent heat dissipation performance, making it a core component of high-efficiency motors.

[0003] Chinese invention patent application CN121791581A discloses a multi-winding device for stator winding production, comprising a worktable, a wire feeding mechanism, and a winding mechanism. The winding mechanism includes a rotating assembly, a translational assembly mounted on the rotating assembly, and a winding assembly mounted on the translational assembly. The winding assembly includes a winding drive structure and a winding fixture. The winding drive structure includes a winding fixing plate, a first side plate, a second side plate, and two rotating shafts, which are rotatably mounted on the first and second side plates, respectively. The two ends of the winding fixture are mounted on the two rotating shafts. The winding fixture includes a winding bar, wire separators, and a wire fixing structure. Multiple wire separators are equidistantly arranged on the winding bar, dividing the winding bar into multiple independent winding areas. Specifically, the wire separators include wire separator blocks sleeved on the winding bar and caps detachably mounted on the wire separator blocks by bolts. The two rotating shafts have mounting grooves on opposite sides and through holes communicating with the mounting grooves. The winding rods have pin holes at both ends. During assembly, the winding rods are placed into the mounting grooves, and the indexing pins are passed through the through holes of the rotating shafts and engaged with the pin holes on the winding rods, thereby achieving a detachable and fixed connection between the winding rods and the rotating shafts.

[0004] The drawback of existing technology is that after the flat copper wire is wound into a coil on the winding bar, the coil needs to be removed from the winding bar. The current method is to remove the winding bar from the rotating shaft, then remove the bolts on the cap, and then remove the wire fixing structure. On the one hand, this cumbersome operation takes a long time and is inefficient; on the other hand, the current manual method of removing the coil is not conducive to achieving automated operation. Summary of the Invention

[0005] This invention provides an automatic winding device for multiple strands of flat copper wire to solve the technical problem of low automation caused by the need for manual removal of coils in the prior art.

[0006] To solve the above problems, the automatic winding equipment for multiple strands of flat copper wire provided by the present invention adopts the following technical solution: The equipment for multiple strands of flat copper wire includes: A winding device includes a winding mounting base and a winding bar component rotatably mounted on the winding mounting base. The winding bar component includes a winding bar and a wire separator provided on the winding bar. The winding device also includes a drive-type wire fixing mechanism for fixing the end of the flat copper wire to the winding bar component; one end of the winding bar component is rotatably mounted on the winding mounting base, and the other end is suspended in the air, or the winding mounting base is provided with a support mechanism for supporting the other end of the winding bar component, and the support mechanism is slidably assembled on the winding mounting base along the extension direction of the rotation axis of the winding bar component. The flat copper wire multi-winding equipment also includes a disassembly and wire-pulling device, which includes a disassembly mechanism and a wire-pulling mechanism. The disassembly mechanism includes a disassembly component and a clamping component arranged in a lifting manner. The disassembly component is used to disassemble the wire separator, and the clamping component is used to clamp the wire separator and remove it from the winding bar. The wire-pulling mechanism includes a wire-pulling component arranged in a lifting manner and a wire-pulling component arranged in a horizontal movement manner. The wire-pulling component is used to pull the coil away from one end of the winding bar after the wire separator is removed.

[0007] The beneficial effects of this solution are as follows: By setting up a drive-type wire-fixing mechanism, the end of the flat copper wire can be fixed, and the end of the flat copper wire can also be loosened when removing the coil. The winding bar component, with one end suspended or equipped with a movable support mechanism, can be positioned with one end suspended during coil removal, facilitating the removal of the coil from one end. By setting up a disassembly and wire-pulling device, the wire separator is disassembled and removed using lifting and clamping components. Then, the coil is directly pulled away along the axial direction of the winding bar using lifting and horizontally movable wire-pulling components. The entire process requires no manual intervention, solving the time-consuming and inefficient problem caused by manually removing the winding bar, bolts, and wire-fixing structures, and improving the degree of automation.

[0008] Furthermore, the winding bar has a locking groove on its side, and the wire separator includes a U-shaped baffle fitted on the winding bar. The U-shaped baffle includes support arms placed on both sides of the winding bar and a top arm connecting the two support arms. The divider also has a latch hinged to one of the support arms at the middle position. The latch has a locking end that extends into the latch groove and a force-receiving end that extends to the top arm. A latch elastic element is provided between the force-receiving end and the top arm. The latch elastic element is used to push the force-receiving end so that the locking end of the latch extends into the latch groove. After applying pressure to the force-receiving end, it is used to drive the locking end to rotate out of the latch groove to achieve unlocking. The disassembly component is a pressing block that presses down on the force-bearing end.

[0009] The beneficial effects of this solution are: the use of a U-shaped baffle plate in conjunction with a hinged latch and a latch elastic element achieves locking with the winding bar; when the top pressure block presses down on the force-bearing end, the locking end can rotate out of the latch groove to unlock, and the subsequent clamping parts can clamp the U-shaped baffle plate, which can quickly disassemble the wire separator.

[0010] Furthermore, the clamping member includes two grippers arranged opposite to each other, and the disassembly mechanism includes a disassembly mounting plate and a gripper drive member disposed on the disassembly mounting plate. The gripper drive member is used to drive the two grippers to move relative to each other. The top pressure block is located between two grippers, and the disassembly and mounting plate is provided with a disassembly drive component for driving the top pressure block to rise and fall.

[0011] Furthermore, the disassembly drive component includes a telescopic component fixed to the disassembly mounting plate, an end plate fixed to the telescopic component, and at least two support rods on the end plate. The support rods are located on both sides of the gripper drive component or pass through the gripper drive component, and the top pressure block is disposed on each support rod.

[0012] Furthermore, the disassembly and wire-pulling device includes a linear module one and an assembly plate disposed on the linear module one, the linear module one having an output end that moves horizontally along the extension direction of the rotation axis of the winding bar; The assembly plate is equipped with a linear module 2 for driving the disassembly mechanism to rise and fall, and the wire-picking mechanism includes a wire-picking component drive component for driving the wire-picking component to rise and fall.

[0013] Furthermore, the flat copper wire multi-winding equipment includes a coil shaping device, which is used to shape the coil before disassembling the separator. The coil shaping device includes two shaping blocks arranged in a lifting manner, which are used to move relative to each other to squeeze both sides of the coil. The shaping blocks are provided with clearance grooves for avoiding the separator.

[0014] The beneficial effects of this solution are as follows: by setting two relatively movable shaping blocks, the two sides of the coil after winding can be squeezed and shaped, changing the tightness of the fit between the coil and the corner of the winding bar, reducing the clamping force, thereby reducing the sliding friction when the coil is pulled off the winding bar, avoiding jamming, and preventing the copper wire enamel layer from being scratched or the coil from deforming; and the avoidance grooves provided on each shaping block can avoid the wire separator, allowing the coil to be shaped before the wire separator is removed, and the coil is still reliably arranged between adjacent wire separators during the shaping process, preventing the coil from shifting or scattering when it is deformed or loosened by force.

[0015] Furthermore, the flat copper wire multi-winding equipment also includes a transfer and unloading device, which includes a horizontally movable unloading trough plate. The movement direction of the unloading trough plate is the extension direction of the rotation axis of the winding bar. The unloading trough plate is used to move to the outside of the winding bar to receive the coil pulled away by the wire puller.

[0016] The beneficial effects of this solution are: by setting a horizontally movable unloading trough plate, and the direction of its movement is consistent with the extension direction of the rotation axis of the winding bar, the unloading trough plate can be moved to the outside of the winding bar to receive the coil pulled away by the wire puller, thus realizing the automatic transfer of the coil from the winding bar to the unloading trough plate and reducing the manual material handling process.

[0017] Furthermore, the transfer and unloading device includes an unloading trough plate mounting base, wherein the unloading trough plate is rotatably mounted on the unloading trough plate mounting base to pour out the coil on the unloading trough plate.

[0018] The beneficial effect of this solution is that after the unloading trough plate receives the coil, it can be tilted or flipped by rotation, so that the coil can automatically slide out of the unloading trough plate by gravity, thus achieving rapid unloading.

[0019] Furthermore, the winding mounting base includes a main board and a winding mounting plate that are perpendicular to each other. The winding bar component is rotatably mounted on the winding mounting plate. The support mechanism includes a support arm drive component provided on the main board. The support arm drive component has an output end that extends and retracts along the rotation axis of the winding bar component. A support arm is provided on the output end of the support arm drive component, and one end of the winding bar is inserted into the support arm to support the winding bar.

[0020] Furthermore, the winding bar component has an axial through hole located on the central axis on one end face of the winding mounting base, and a radial through hole communicating with the axial through hole on the winding bar. The driven wire fixing mechanism includes a clamping block slidably assembled in a radial through hole, a pressure plate disposed on a winding bar component and radially spaced from the clamping block, and a push shaft slidably assembled in an axial through hole. At least one of the push shaft and the clamping block is provided with a redirecting slope. When the push shaft approaches the clamping block, it pushes the clamping block toward the pressure plate through the redirecting slope to clamp the flat copper wire end located between the pressure plate and the clamping block. The driven wire fixing mechanism also includes a clamping block reset elastic member that drives the clamping block away from the pressure plate. The winding mounting base is equipped with a push shaft drive component for driving the push shaft to move.

[0021] Through the coordinated operation of the clamping block, pressure plate, clamping block reset elastic element, and push shaft, the automatic clamping and release of the flat copper wire end is achieved. The entire process requires no manual operation, improving the degree of automation and production efficiency. Since the axial perforation is set on the central axis of the winding bar component, it provides an independent and concentric axial sliding channel for the push shaft, ensuring that the axial pushing motion of the push shaft does not interfere with the high-speed rotational motion of the winding bar component.

[0024] Embodiments of the automatic winding device for multiple strands of flat copper wire provided by the present invention: like Figures 1 to 13 As shown, the automatic winding equipment for multiple strands of flat copper wire (hereinafter referred to as the winding equipment) includes a workbench 100, two winding modules, a transfer and unloading device 700, and a belt conveyor 800. For ease of description, the spacing between the two winding modules is defined as the left-right direction. Each winding module includes a wire feeding device 200, a cam divider 300, a winding device 400, a wire straightening device 500, and a wire disassembly and pulling device 600.

[0025] The wire feeding device 200 feeds flat copper wire 900 to the winding device 400. Its structure is the same as that of the wire feeding mechanism in Chinese invention patent application with publication number CN121791581A, and will not be described in detail here.

[0026] like Figure 3 As shown, the cam divider 300 is fixedly installed on the workbench 100, located on one side of the wire feeding device 200 in the front-back direction. The cam divider 300 has an output end that rotates around a vertical axis, and a rotating platform mounting base 301 is fixedly installed on the output end of the cam divider 300.

[0027] Each winding module includes two winding devices 400, which are symmetrically mounted on the rotating platform mounting base 301. In use, one winding device 400 is directly opposite the wire feeding device 200, and the other is directly opposite the wire assembly device 500 and the wire disassembly and pulling device 600.

[0028] like Figures 4 to 7 As shown, the winding device 400 includes a rotating component 401, a translating component 402, and a winding component 403. The rotating component 401 is mounted on the rotating platform fixed base 301, the translating component 402 is mounted on the rotating component 401, and the winding component 403 is mounted on the translating component 402. The structure of the rotating component 401 and the translating component 402 is the same as that of the rotating component and the translating component in Chinese invention patent application with publication number CN121791581A, and will not be described again here. The rotating component 401 drives the winding component 403 to rotate, and the translating component 402 drives the winding component 403 to move left and right.

[0029] The winding assembly 403 includes a winding mounting base, a winding bar component, a drive-type wire fixing mechanism, a support mechanism, and a winding drive mechanism.

[0030] The winding mounting base includes a main board 404 and a winding mounting plate 405 that are perpendicular to each other. The main board 404 is fixedly mounted on the translation component 402, the winding bar component and the winding drive mechanism are mounted on the winding mounting plate 405, and the support mechanism is mounted on the main board 404.

[0031] One end of the winding bar component is rotatably mounted on the winding mounting plate 405 about a left-right extending central axis. The winding bar component includes a rotating shaft 406, an adapter block 407, a winding bar 408, a wire separator 409, and a positioning protrusion 410. A flange 411 is mounted on the winding mounting plate 405, and the flange 411 penetrates the winding mounting plate 405. The rotating shaft 406 rotatably passes through the flange 411. The adapter block 407 is fixedly mounted on the rotating shaft 406, and the winding bar 408 is fixedly mounted on the adapter block 407. An axial through hole 412 is formed on the end face of the rotating shaft 406 opposite to the adapter block 407. The axial through hole 412 is located on the central axis of the winding bar component, passes through the rotating shaft 406 and the adapter block 407, and extends into the winding bar 408. A radial through hole 413 is provided on the end face of the winding bar 408 that is connected to the adapter block 407. The radial through hole 413 communicates with the axial through hole 412. The outer diameter of the adapter block 407 is larger than the outer diameter of the winding bar 408.

[0032] In this embodiment, the cross-section of the winding rod 408 used for winding is rectangular. Multiple locking slots 414 are provided on the side of the winding rod 408, and slots 415 are provided on adjacent side surfaces. The number of wire dividers 409 is equal to and corresponds one-to-one with the number of locking slots 414. Each wire divider 409 includes a U-shaped baffle 416, a latch 417, and a latching elastic element 418. The U-shaped baffle 416 includes two parallel support arms 419 and a top arm 420 connecting the two support arms 419. A protrusion (not shown in the figure) is provided on the inner side of the top arm 420. When the U-shaped baffle 416 is fitted onto the winding rod 408, the protrusion inserts into the slot 415, thereby limiting the position of the U-shaped baffle 416.

[0033] One of the support arms 419 has a groove, and a latch 417 is hinged in the groove. The hinge axis of the latch 417 extends in the left-right direction. Here, the latch 417 is hinged to the support arm 419 at the middle position, and its two ends are a locking end 421 and a force-receiving end 422, respectively. The locking end 421 is used to extend into the latch groove 414 so that the latch 417 hooks onto the winding bar 408; the force-receiving end 422 extends to the outside of the top arm 420, and a latch elastic element 418 is press-fitted between the force-receiving end 422 and the top arm 420. Here, the latch elastic element 418 is a compression spring. The locking elastic element 418 applies an elastic force to the force-bearing end 422, causing the locking end 421 to swing toward the winding bar 408 and enter the locking groove 414. When the force-bearing end 422 is pressed, the locking elastic element 418 is compressed, and the locking end 421 swings away from the winding bar 408, separating the locking end 421 from the locking groove 414. At this time, the wire separator 409 can be removed.

[0034] The positioning protrusion 410 is located at the end of the winding bar 408. It has a conical tip structure, which facilitates its entry into the support mechanism, so that the support mechanism and the winding mounting plate 405 can support the winding bar component together.

[0035] The driven wire fixing mechanism is used to fix the end of the flat copper wire 900 to the winding bar component. The driven wire fixing mechanism includes a clamping block 423, a pressure plate 424, a push shaft 425, a push shaft drive component, and a clamping block elastic reset component 426. The clamping block 423 is slidably assembled in the radial through hole 413 of the winding bar component. The inner end of the clamping block 423 has a clamping block inclined surface 427, which is inclined in the direction of extending outward from the central axis of the winding bar component and toward the direction of the adapter block 407. The inner end of the clamping block 423 has a support portion 428 protruding along the axial direction of the winding bar component. The outer end face of the clamping block 423 is provided with a wire groove 430, which is used to accommodate the end of the flat copper wire 900.

[0036] The pressure plate 424 is fixed on the adapter block 407, with one end extending to the outside of the radial through hole 413. Since the outer diameter of the adapter block 407 is larger than the outer diameter of the winding bar 408, there is a gap between the pressure plate 424 and the winding bar 408, which is used to insert the flat copper wire 900.

[0037] The push shaft 425 is slidably assembled in the axial through hole 412. The push shaft drive component 431 here is a thin cylinder. The thin cylinder is fixedly installed on the winding mounting plate 405 by four support columns 432. Specifically, the thin cylinder and the adapter block 407 are respectively placed on both sides of the winding mounting plate 405. The thin cylinder and the push shaft 425 are assembled together in a circumferentially rotatable and axially fixed manner. Specifically, a connecting frame 433 is fixedly installed at the end of the push shaft 425. The connecting frame 433 has an inwardly turned edge 434. A stop flange 435 is fixedly installed at the output end of the thin cylinder. The stop flange 435 has an outwardly turned edge. The stop flange 435 extends from one side into the connecting frame 433. The inwardly turned edge 434 and the stop flange 435 stop each other axially, so that the thin cylinder can drive the push shaft 425 to move, and the push shaft 425 will not drive the thin cylinder to rotate when it rotates.

[0038] The elastic reset component 426 of the clamping block here is a compression spring. One end of the elastic reset component 426 is fixed to the support portion 428 of the clamping block 423, and the other end is fixed to the pressure plate 424. The elastic reset component 426 applies an elastic force to the clamping block 423, causing the clamping block 423 to move away from the pressure plate 424. When the push shaft 425 pushes the clamping block inclined surface 427 of the clamping block 423, the clamping block 423 overcomes the elastic force of the elastic reset component 426 and moves closer to the pressure plate 424, pressing the end of the flat copper wire 900.

[0039] The outer diameter of the end of the winding bar 408 connected to the adapter block 407 is larger. The winding bar 408 has an extension protrusion 429. The extension protrusion 429 is arranged at an angle. When the flat copper wire 900 is wound, the extension protrusion 429 guides the flat copper wire 900 to wind around the rectangular part of the winding bar 408.

[0040] The support mechanism includes a fixing block 436, a positioning pin 437, a support arm drive component 438, and a support arm 439. The fixing block 436 is mounted on the main board 404. Specifically, a row of multiple positioning holes 440 is formed on the main board 404, and the multiple positioning holes 440 are arranged at intervals in the left-right direction. The fixing block 436 has a pin hole. In use, the appropriate positioning hole 440 is selected according to the length of the winding bar 408, and then the positioning pin 437 is passed through the pin hole of the fixing block 436 and inserted into the positioning hole 440.

[0041] The support arm drive component 438 is mounted on the fixed block 436. Here, the support arm drive component 438 is a cylinder. The cylinder body of the support arm drive component 438 is fixed to one side of the fixed block 436, and the piston rod of the support arm drive component 438 passes through to the other side of the fixed block 436. The support arm drive component 438 has a telescopic end that can extend and retract left and right.

[0042] The support arm 439 is fixedly installed on the telescopic end of the support arm drive 438. The support arm 439 extends along the front-back direction as a whole, and a positioning groove is provided at one end. The positioning groove is for the positioning protrusion 410 on the winding bar 408 to fit into, thereby supporting the winding bar 408.

[0043] The winding drive mechanism employs belt drive and includes a synchronous pulley 441, a synchronous belt 442, and a synchronous motor 443. The synchronous pulley 441 is fixedly mounted on the rotating shaft 406, and the synchronous motor 443 is fixedly mounted on the winding mounting plate 405. Its output end is also equipped with a synchronous pulley 441. The synchronous belt 442 passes over all the synchronous pulleys 441. When the synchronous motor 443 rotates, it drives the winding bar component to rotate. It should be noted that in other embodiments, one or more reduction gears can be provided on the synchronous motor 443, and synchronous pulleys 441 can be installed on the output end of the reduction gears; additional tensioning pulleys can also be added to achieve tensioning.

[0044] like Figures 8 to 10 As shown, the winding device 500 is used to organize the wound coil 901 to facilitate the subsequent removal of the winding bar 408. It includes a base, a shaping component, and a driving component.

[0045] The base includes an assembly frame 501, a fixing plate 502, a linear slide rail 503, a mounting bracket, and a cylinder 504. The fixing plate 502 is fixedly installed on the assembly frame 501. There are two linear slide rails 503, both of which extend in the vertical direction. The mounting bracket is slidably installed on the linear slide rail 503 in the vertical direction. The cylinder 504 is fixedly installed on the fixing plate 502 and is connected to the mounting bracket to drive the mounting bracket to rise and fall.

[0046] The mounting frame includes a shaping slide plate 505 and a splicing plate 506. The shaping slide plate 505 is slidably mounted on two linear slide rails 503. The splicing plate 506 is fixedly mounted on the shaping slide plate 505 and is arranged in an overall cantilevered manner. The splicing plate 506 is composed of multiple plates.

[0047] The shaping assembly includes two shaping blocks, which are slidably mounted on the splicing plate 506 in a left-right direction. Each shaping block includes a pressure block mounting base 507 and a pressure block 508. The pressure block 508 is detachably mounted on the pressure block mounting base 507, specifically by bolt connection. The pressure block 508 is used to directly compress the coil 901. A clearance groove 509 is provided on the side of the pressure block 508 to avoid the wire separator 409 on the winding bar 408.

[0048] When the two shaping blocks approach each other, the two pressing blocks 508 can jointly squeeze the side wall of the coil 901, causing the coil 901 to deform and reducing the tightness between the coil 901 and the winding bar 408.

[0049] The shaping block is slidably mounted on the base via linear slide rail 510. Specifically, there are two linear slide rails 510 arranged front to back, and the two linear slide rails 510 are respectively fixedly mounted on the top of the two pressure block mounting seats 507. The linear slide rails 510 and the base are slidably assembled together. In other embodiments, the linear slide rails 510 are fixedly mounted on the base, and the pressure block mounting seats 507 are slidably assembled on the linear slide rails 510.

The limit blocks 515 are fixedly mounted on the base. The screws 516 slide through the limit blocks 515, and the heads of the screws 516 are screwed into the pressure block mounting seats 507, thus fixing the screws 516 and the pressure block mounting seats 507 together. The elastic element 517 is a spring, specifically a tension spring. The elastic element 517 is sleeved on the outside of the screws 516. One end of the elastic element 517 is connected to the limit block 515, and the other end is connected to the pressure block mounting seat 507. After the elastic element 517 applies an elastic force to the pressure block mounting seats 507, it causes the two pressure block mounting seats 507 to move away from each other.

[0052] The electric cylinder mounting bracket 518 is fixedly mounted on the splicing plate 506, and the servo electric cylinder 519 is fixedly mounted on the electric cylinder mounting bracket 518.

[0053] The drive block 513 is fixedly installed at the bottom of the adaptive slide rail 512. A groove is formed at the bottom of the drive block 513, with a larger bottom opening and a smaller top opening. The groove has two opposing second inclined surfaces 521, with the distance between the two inclined surfaces 521 gradually increasing from top to bottom. In other embodiments, the adaptive slide rail 512 is fixedly assembled with the transition connector 511, while the drive block 513 is slidably assembled with the adaptive slide rail 512.

[0054] There are two inclined sliders 514, which are fixedly installed on the top of two pressure block mounting bases 507 respectively. The opposite sides of the two inclined sliders 514 each have a first inclined surface 520, and the distance between the two first inclined surfaces 520 gradually increases from top to bottom.

The grippers 606 are fixedly installed on the two moving output ends of the pneumatic gripper. The two grippers 606 can clamp the two arms 419 of the U-shaped baffle 416.

[0059] The disassembly component 607 here is a top plate. The function of the top plate is to press upward on the force-bearing end 422 of the latch 417. It should be noted that when disassembling the divider 409, the top arm 420 of the divider 409 is located below the two support arms 419. The disassembly component driving component is used to drive the disassembly component 607 to rise and fall. The disassembly component driving component includes a second cylinder 608, a cylinder end plate 609, and support rods 610. The second cylinder 608 is fixedly installed on the disassembly mounting plate 604. The second cylinder 608 constitutes a telescopic component that drives the cylinder end plate 609 to rise and fall. The cylinder end plate 609 is fixedly installed on the two cylinders 608. There are two support rods 610. The two support rods 610 are fixedly installed on the cylinder end plate 609 and extend upward.

[0061] The transfer and unloading device 700 corresponds to two winding modules and can receive the coil 901 removed by the disassembly and wire pulling device 600. It includes a linear module 3 701, an unloading trough plate mounting base, an unloading trough plate 702, and an unloading trough plate driving component. The linear module 3 701 is fixedly installed on the workbench 100, specifically located on the front and rear sides of the disassembly and wire pulling device 600. The linear module 3 701 covers the two winding devices 400 in the left and right direction and has an output end that moves left and right.

[0062] The unloading chute mounting base is installed on the output end of the linear module 3 701, which can drive the unloading chute 702 to move left and right. The unloading chute mounting base includes a back plate 703 and a bearing mounting plate 704. The back plate 703 is installed on the linear module 3 701, and there are two bearing mounting plates 704, which are symmetrically installed on the back plate 703 in the left-right direction. An unloading chute shaft 705 is rotatably mounted between the two bearing mounting plates 704 via bearings. Two extension rods 706 are fixedly mounted on the unloading chute shaft 705, and the unloading chute 702 is fixedly mounted on the two extension rods 706. When the unloading chute shaft 705 rotates, it can drive the unloading chute 702 to rotate.

[0063] The unloading trough plate 702 is a U-shaped plate with its opening facing upwards. Its left and right ends are open and can be moved to the outside of the winding bar 408 and the coil 901.

[0064] The unloading chute drive component can drive the unloading chute 702 to swing back and forth. The unloading chute drive component includes a cylinder 707, a T-shaped plate 708, a rack 709, and a gear 710. The cylinder 707 is fixedly mounted on the back plate 703. The T-shaped plate 708 is slidably mounted between two bearing mounting plates 704 in the vertical direction. The cylinder 707 is connected to the T-shaped plate 708 and drives the T-shaped plate 708 to rise and fall. The rack 709 is fixedly mounted on the T-shaped plate 708. The gear 710 is fixedly mounted on the unloading chute shaft 705. The rack 709 meshes with the gear 710. When the rack 709 moves up and down, it can drive the gear 710 to rotate. After the gear 710 rotates, it can drive the unloading chute shaft 705 and the unloading chute 702 to rotate.

[0065] like Figure 1 and Figure 2 As shown, the belt conveyor 800 is installed on the workbench 100, located on the front and rear sides of the transfer and unloading device 700. After the unloading trough plate 702 rotates, the coil 901 falls onto the belt conveyor 800, and the belt conveyor 800 transfers the coil 901 to other working areas.

[0066] Usage: In the initial state, one of the winding devices 400 corresponds to the wire feeding device 200. The push shaft drive 431 drives the push shaft 425 away from the clamping block 423, separating the clamping block 423 from the pressure plate 424. The wire feeding device 200 feeds the flat copper wire 900 between the pressure plate 424 and the clamping block 423. The push shaft drive 431 drives the push shaft 425 to push the clamping block 423, so that the pressure plate 424 and the clamping block 423 together clamp the flat copper wire 900. The support arm drive 438 drives the support arm 439 to approach the winding bar 408. The positioning protrusion 410 of the winding bar 408 passes into the support arm 439 to support the winding bar 408. Then the winding operation begins. After winding, the flat copper wire 900 is cut. Cylinder 504 drives splicing plate 506 to move downward. Two shaping blocks are located on both sides of coil 901. Servo electric cylinder 519 drives drive block 513 to move downward. Drive block 513 pushes inclined slider 514, so that the two shaping blocks are close to each other and squeeze coil 901. During this process, if one of the shaping blocks contacts coil 901 first, coil 901 will apply a reaction force to the shaping block, so that drive block 513 slides on adaptive slide rail 512, thereby achieving automatic adjustment and centering.

[0067] After shaping, the support arm drive 438 moves the support arm 439 away from the winding bar 408, and the push shaft drive 431 moves the push shaft 425 away from the clamping block 423, releasing the end of the coil 901. The second linear module 603 moves the gripper drive 605, gripper 606, and disassembly component 607 upwards. The disassembly component 607 presses against the force-bearing end 422 to unlock the wire separator 409. The two grippers 606 clamp the bottom of the wire separator 409 to prevent clamping the coil 901. Then, the second linear module 603 moves the grippers 606 downwards, separating the wire separator 409 from the winding bar 408. The wire-pulling component rises and, driven by the first linear module 601, pulls the coil 901 away from the winding bar 408. Before the coil 901 is removed, the linear module 3 701 moves the unloading trough plate 702 to the outside of the coil 901. After receiving the coil 901, the linear module 3 701 moves the unloading trough plate 702 away from the winding bar 408. When it moves to the belt conveyor 800, the cylinder 4 707 moves the rack 709 upward, and drives the unloading trough plate 702 to rotate through the gear 710, tilting the coil 901 onto the belt conveyor 800.

[0068] In this embodiment, the clamping block 423 is provided with a clamping block inclined surface 427, which can realize the redirection of force transmission, and it is a redirection slope. In other embodiments, the redirection slope can be an arc surface, and the redirection slope can be provided only on the clamping block 423 or on the push shaft 425, or both the clamping block 423 and the push shaft 425 can be provided with redirection slopes.

[0069] In other embodiments, the drive-type wire fixing mechanism can be an electric cylinder mounted on the winding bar component, which presses the end of the flat copper wire 900 onto the winding bar component. In this case, in order to supply power to the electric cylinder, a conductive slip ring can be provided between the rotating shaft 406 and the flange 411, which satisfies the rotation requirement and can also supply power.

[0070] In this embodiment, a support mechanism is installed on the winding mounting base, which supports the winding bar 408 during winding. In other embodiments, the support mechanism can be omitted, and the winding bar component is suspended in the air.

[0071] In the shaping device of this embodiment, in order to drive the two shaping blocks to move relative to each other, a driving block 513, a sliding block 514, a limiting block 515, a screw 516, and an elastic element 517 are configured. In other embodiments, a lead screw and nut mechanism can be set to drive the two shaping blocks to move relative to each other. The two ends of the lead screw are provided with two sections of threads with opposite directions of rotation. The two sections of threads are inserted into different shaping blocks. By rotating the lead screw, the two shaping blocks can be driven to move closer to each other or further away from each other.

[0072] In this embodiment, a latch 417 is hinged to the winding rod 408, and the disassembly component 607 unlocks the part by pressing against the latch 417. In other embodiments, the wire divider may only include a U-shaped baffle 416, the top arm 420 of which is screwed onto the winding rod 408. Here, the disassembly component 607 is an electric screwdriver. During disassembly, the top arm 420 is located below the winding rod 408, and the disassembly component 607 loosens the screw. Then, the two jaws 606 clamp and remove the wire divider.

[0073] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
