[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention can expand or reduce the support range of the support base by setting a support assembly and adjusting the position of the support plate, so that it can adapt to motor stators of different sizes and improve the versatility of the device. At the same time, it can ensure that the support base will not touch the terminal of the stator when it contacts the bottom of the stator, thereby avoiding interference with the winding work.

[0017] 2. The present invention sets a fixing component and rotates the threaded rod in the fixing cylinder. The rotation of the threaded rod drives the threaded ring to move downward. The movable rod on the outside of the threaded ring pushes the slider to slide in the limit sleeve as the threaded ring moves, so that the outer support plate on the outside of the slider is expanded outward.

[0019] 4. The present invention adjusts the position of the motor stator by setting a limit assembly so that the wiring terminal of the motor stator is located between the two triangular limit frames in the limit assembly, and then adjusts the position of the sliding plate on the fixed plate by rotating the threaded column so that the triangular limit frames on both sides are in contact with the wiring terminal of the motor stator, so that the triangular limit frames on both sides can be flexibly adjusted according to the size and position of different motor stator wiring terminals.

[0020] 5. The present invention provides a triangular limit frame to ensure that the wire harness can accurately slide along the inclined surface of the triangular limit frame onto the surface of the stator terminal when winding, thereby preventing the wire harness from deviating from the terminal during the winding process and ensuring that the wire harness can accurately slide onto the surface of the stator terminal.

[0021] 6. The present invention further limits the position of the copper wire by setting an arc-shaped limit rod to ensure that it can slide along the inclined surface of the triangular limit frame. The proximity of the arc-shaped limit rod provides additional constraints for the copper wire to prevent the copper wire from deviating from the predetermined trajectory during the winding process. It cooperates with the triangular limit frame to form a more stable guiding channel to ensure that the copper wire can stably move along the predetermined direction.

[0022] 7. The present invention provides a mounting component, and the extension of the telescopic rod can make the assembly plate drive the friction plate to move upward, so that it contacts the outside of the winding drum, thereby increasing the friction force when the winding drum rotates. This increase in friction can play a role in controlling the tension force. In the winding process, appropriate tension force is crucial to ensure the winding quality. If the tension force is too small, the copper wire may become loose, resulting in loose and uneven winding; if the tension force is too large, the copper wire may break or damage the motor stator. By adjusting the friction between the friction plate and the winding drum, the tension force can be accurately controlled, making the winding process more stable and reliable.

[0023] 8. The present invention sets a counterweight component and rotates the adjusting screw to make the counterweight slide along the inner wall of the rectangular sleeve at the bottom of the mounting ring, thereby adjusting the position of the counterweight so that when the shaft rotates, the weight on both sides of the shaft is the same, ensuring that the shaft rotates smoothly and reducing the adverse effects caused by imbalance. The position of the counterweight is adjusted to adapt to different weight distribution conditions. This flexibility enables the device to meet various winding requirements and improves the versatility and adaptability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the winding device 2 is used to fix the copper wire and perform the winding operation to complete the working process;

[0039] The winding device 2 is used to fix the copper wire and perform winding operations. The bottom of the winding device 2 is fixedly connected to the top of the base 1.

The outer wall of the rotating shaft 23 is fixedly connected to an assembly component 24. The outer wall of the rotating shaft 23 is rotatably connected to The limit assembly 25; the assembly assembly 24 includes a fixed ring 241, the outer wall of the fixed ring 241 is fixedly connected to a counterweight component 244, the top of the counterweight component 244 is fixedly connected to a support frame 242, the top of the support frame 242 is fixedly connected to a threading tube 243, and the top of the fixed ring 241 is fixedly connected to a mounting component 245; the mounting component 245 includes a mounting frame 451, the top of the mounting frame 451 is fixedly connected to a pressure plate 452 by bolts, and the top of the mounting frame 451 is movably mounted with a winding drum 453, and the mounting The inner side of the mounting frame 451 is fixedly connected with a telescopic rod 454, the top of the telescopic rod 454 is fixedly connected with an assembly plate 455, and the top of the assembly plate 455 is fixedly connected with a friction plate 456; the bottom of the bracket 21 is fixedly connected with the top of the base 1 by bolts, the outer wall of the rotating shaft 23 is rotatably connected with the top of the bracket 21 by a bearing, the inner side of the fixing ring 241 is fixedly connected with the outer wall of the rotating shaft 23, and the bottom of the mounting frame 451 is fixedly connected with the top of the fixing ring 241; the counterweight component 244 includes a mounting ring 401, A rectangular sleeve 402 is fixedly connected to the bottom of the mounting ring 401, a counterweight 403 is slidably connected to the inner side of the rectangular sleeve 402, an adjusting screw 404 is threadedly connected to the inner wall of the counterweight 403, the outer side of the adjusting screw 404 is rotatably connected to the center of the rectangular sleeve 402, the inner side of the mounting ring 401 is fixedly connected to the outer wall of the fixing ring 241, the driving motor 22 on the top of the bracket 21 is started, driving the rotating shaft 23 to rotate, and the assembly component 24 fixedly connected to the outer wall of the rotating shaft 23 rotates accordingly, and the winding operation is performed;

[0040] The fixing ring 241 in the assembly component 24 serves to connect and fix other components. The weight component 244 on the outer wall of the fixing ring 241 can adjust the center of gravity of the entire winding device 2 to ensure the stability of the winding process. The threading tube 243 on the top of the support frame 242 is used to guide the copper wire so that the copper wire can be accurately wound on the triangular limit frame 254.

[0041] The winding drum 453 in the mounting component 245 is used to place the copper wire to be wound. The winding drum 453 can be fixed on the mounting frame 451 through the pressing plate 452 so that it can rotate along the surface of the winding drum 453. At the same time, the extension of the telescopic rod 454 can make the assembly plate 455 drive the friction plate 456 to move upward, so that it contacts the outside of the winding drum 453, thereby increasing the friction force when the winding drum 453 rotates. This increase in friction can play a role in controlling the tension. In the winding process, appropriate tension is crucial to ensure the winding quality. If the tension is too small, the copper wire may relax, resulting in loose and uneven winding; if the tension is too large, the copper wire may break or damage the motor stator. By adjusting the friction between the friction plate 456 and the winding drum 453, the tension can be precisely controlled to make the winding process more stable and reliable. Before the rotating shaft 23 rotates, the adjusting screw 404 is rotated to make the counterweight 403 slide along the inner wall of the rectangular sleeve 402 at the bottom of the mounting ring 401, thereby adjusting the position of the counterweight 403 so that when the rotating shaft 23 rotates, the weight on both sides of the rotating shaft 23 is the same, ensuring that the rotating shaft 23 rotates smoothly and reducing the adverse effects caused by imbalance. The position of the counterweight 403 is adjusted to adapt to different weight distribution conditions.

During the winding process, the rotating ring 251 rotates around the rotating shaft 23, and then the arc limit rod 6 is rotated to make it close to the triangular limit frame 254. When the gap between the arc limit rod 6 and the triangular limit frame 254 is just enough for the copper wire to pass through, the position of the arc limit rod 6 is fixed by rotating the locking bolt 7, which can further limit the position of the copper wire and ensure that it can slide down along the inclined surface of the triangular limit frame 254. The approach of the arc limit rod 6 provides additional constraints for the copper wire, preventing the copper wire from deviating from the predetermined trajectory during the winding process.

At this time, the supporting plate 343 can be pulled outward, and the limiting plate 344 can limit the position of the supporting plate 343 to ensure its stable sliding. Then, the limiting bolt 346 can be used to fix the position of the supporting plate 343. By adjusting the position of the supporting plate 343, the supporting range of the supporting base 341 can be expanded or reduced, which can adapt to motor stators of different sizes and improve the versatility of the device.

The servo motor 32 on the top of the moving seat 31 provides power for the support assembly 34 and can adjust the angle of the motor stator.

[0049] When fixing the motor stator, the motor stator is placed on the support assembly 34 through the fixing assembly 35. At this time, the limiting bolt 346 is rotated to make it slide upward along the L-shaped plate 347 and disengage from the insertion hole 345 opened on the surface of the support plate 343. At this time, the support plate 343 can be pulled outward, and the limiting plate 344 can limit the position of the support plate 343 to ensure its stable sliding. Subsequently, the position of the support plate 343 can be fixed by the limiting bolt 346. By adjusting the position of the support plate 343, the support range of the support base 341 can be expanded or reduced. This can adapt to motor stators of different sizes and improve the versatility of the device. At the same time, it can also ensure that the support base 341 will not touch the terminal of the stator when it contacts the bottom of the stator, thereby avoiding its interference with the winding work.

[0050] Then, the threaded rod 352 in the fixed cylinder 351 is rotated, and the threaded rod 352 rotates to drive the threaded ring 353 to move downward. The movable rod 354 on the outside of the threaded ring 353 pushes the slider 355 to slide in the limit sleeve 357 as the threaded ring 353 moves, so that the outer support plate 356 on the outside of the slider 355 is expanded outward. After the outer support plate 356 is expanded outward, it contacts the inner wall of the motor stator, ensuring that the motor stator remains stable during the winding process without shaking or displacement, and can meet the winding requirements of motor stators of different specifications.

[0051] At the same time, when the movable rod 354 pushes the slider 355 to slide in the limiting sleeve 357, the elastic force of the compression spring 359 is gradually released, and the slider 355 can be driven to slide toward the outside of the limiting sleeve 357 through the auxiliary installation plate 358. The elastic force release of the compression spring 359 provides additional auxiliary power for the slider 355 to slide toward the outside of the limiting sleeve 357, ensuring that the slider 355 slides more smoothly and stably.

[0052] When the winding device 2 is in use, the position of the motor stator is first adjusted so that the wiring terminal of the motor stator is located between the two triangular limiting frames 254 in the limiting assembly 25, and then the position of the sliding plate 253 on the fixed plate 252 is adjusted by rotating the threaded column 255 so that the triangular limiting frames 254 on both sides are in contact with the wiring terminal of the motor stator, so that the triangular limiting frames 254 on both sides can be flexibly adjusted according to the size and position of different motor stator wiring terminals;

[0053] Ensure that the wire harness can accurately slide along the inclined surface of the triangular limit frame 254 onto the surface of the stator terminal when winding, prevent the wire harness from deviating from the terminal during the winding process, and ensure that the wire harness can accurately slide onto the surface of the stator terminal. During the winding process, the rotating ring 251 rotates around the rotating shaft 23.

[0054] Then, the arc limit rod 6 is rotated to approach the triangular limit frame 254. When the gap between the arc limit rod 6 and the triangular limit frame 254 is just enough for the copper wire to pass through, the position of the arc limit rod 6 is fixed by rotating the locking bolt 7, which can further limit the position of the copper wire and ensure that it can slide along the inclined surface of the triangular limit frame 254. The approach of the arc limit rod 6 provides additional constraints for the copper wire to prevent it from deviating from the predetermined trajectory during the winding process. It cooperates with the triangular limit frame 254 to form a more stable guide channel to ensure that the copper wire can move stably along the predetermined direction.

[0055] Afterwards, the driving motor 22 on the top of the bracket 21 is started, driving the rotating shaft 23 to rotate, and the assembly component 24 fixedly connected to the outer wall of the rotating shaft 23 rotates accordingly to perform the winding operation;

[0056] The fixing ring 241 in the assembly component 24 serves to connect and fix other components. The weight component 244 on the outer wall of the fixing ring 241 can adjust the center of gravity of the entire winding device 2 to ensure the stability of the winding process. The threading tube 243 on the top of the support frame 242 is used to guide the copper wire so that the copper wire can be accurately wound on the triangular limit frame 254.

[0057] The winding drum 453 in the mounting component 245 is used to place the copper wire to be wound. The winding drum 453 can be fixed on the mounting frame 451 through the pressing plate 452 so that it can rotate along the surface of the winding drum 453. At the same time, the extension of the telescopic rod 454 can make the assembly plate 455 drive the friction plate 456 to move upward, so that it contacts the outer side of the winding drum 453, thereby increasing the friction force when the winding drum 453 rotates. This increase in friction can play a role in controlling the tension. In the winding process, appropriate tension is crucial to ensure the winding quality. If the tension is too small, the copper wire may relax, resulting in loose and uneven winding; if the tension is too large, the copper wire may break or damage the motor stator. By adjusting the friction between the friction plate 456 and the winding drum 453, the tension can be accurately controlled to make the winding process more stable and reliable.

[0058] Before the rotating shaft 23 rotates, the adjusting screw 404 is rotated to make the counterweight 403 slide along the inner wall of the rectangular sleeve 402 at the bottom of the mounting ring 401, thereby adjusting the position of the counterweight 403 so that when the rotating shaft 23 rotates, the weights on both sides of the rotating shaft 23 are the same, ensuring that the rotating shaft 23 rotates smoothly and reducing the adverse effects caused by imbalance. The position of the counterweight 403 is adjusted to adapt to different weight distribution conditions. This flexibility enables the device to meet various winding requirements and improves the versatility and adaptability of the device.
