Abstract
Description
Technical Field
[0001] This utility model relates to the field of winding machine technology, and more specifically, to a multi-station segmented stator core winding machine. Background Technology
[0002] An electric motor generally consists of two parts: a rotor and a stator. The rotor is the rotating part of the motor, while the stator is the stationary part. The stator generally includes an iron core and windings mounted on the iron core. Typically, the coils are wound around the teeth of the iron core.
[0003] The coils on the iron core of a motor are generally wound using a winding machine. However, when winding the stator of a large or long iron core in a synchronous motor, the enameled wire used for winding is relatively thick, and there are certain requirements for the number of coil turns within a limited space. When using existing winding machines, it is difficult to ensure that the enameled wire does not bend. Furthermore, due to the large and long structure of the iron core itself, it is difficult to control the winding point during winding, resulting in low winding accuracy.
[0004] A search revealed that Chinese patent CN219980625U discloses a stator core winding machine, which controls the winding point of enameled wire through a wire nozzle; by rotating a first motor and a second motor in combination, the angle of the core and the relative position of the winding point are controlled, and the enameled wire is wound onto the core in an orderly manner, allowing for more turns of coil to be wound in a limited space; a cylinder is used to control the core ejector pin to position the core on the core fixture, ensuring precise positioning.
[0005] In actual use, the aforementioned stator core winding machine lacks effective positioning methods during stator core installation, resulting in deviations in the installation positions of different stator cores. This causes the winding to fail to follow the predetermined trajectory and position, leading to winding misalignment. Furthermore, the stator core winding process is performed separately, and the winding station stops working when loading or unloading materials, thus reducing production efficiency. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a multi-station segmented stator core winding machine to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A multi-station segmented stator core winding machine includes a base, a winding machine mounted on the top of the base, a wire outlet box mounted on one side of the winding machine, a tensioning mechanism installed inside the wire outlet box, and a replacement component mounted on the top of the base.
[0009] The replacement component includes a first servo motor, with a rotating plate fixedly connected to the output end of the first servo motor. A rotating ring is fixedly connected to the bottom end of the rotating plate. A sliding groove is formed on the upper surface of the base, with the inner side of the sliding groove slidably connected to the outer side of the rotating ring. Multiple second servo motors are installed inside the rotating plate. A first turntable is fixedly connected to the output end of the second servo motor. A first positioning ring is fixedly connected to the top end of the first turntable. Multiple support frames are fixedly connected to the top end of the rotating plate. A threaded rod is rotatably connected inside the support frame. A knob is fixedly connected to the top end of the threaded rod. A movable disc is threadedly connected to the outer side of the threaded rod. Two guide posts are slidably connected inside the movable disc. The guide posts are fixedly connected to the inner side of the support frame. A second turntable is rotatably connected to the bottom end of the movable disc. A second positioning ring is fixedly connected to the bottom end of the second turntable. A stator core is provided between the second turntable and the first turntable.
[0010] By adopting the above technical solution, the stator core can be positioned during installation, ensuring that the installation position of the stator core remains consistent. Multiple workstations can be alternated, reducing equipment downtime and enabling continuous production.
[0011] As a further description of the above technical solution: the tensioning mechanism includes a cable outlet tube, and three connecting shells are installed on the top of the cable outlet box. The cable outlet tube extends through the cable outlet box into the interior of the connecting shells. A third servo motor is installed inside the connecting shells. A third turntable is fixedly connected to the output end of the third servo motor. The third turntable is rotatably connected to the interior of the connecting shells. Two wheels are rotatably connected to one side of the third turntable.
[0012] By adopting the above technical solution, the tension of the copper wire can be adjusted, which helps to improve the winding quality.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. By setting up replacement components, compared with the existing technology, the first positioning ring and the second positioning ring can be used to position the stator core during installation, so that the installation positions of multiple stator cores can be kept consistent. This can reduce winding misalignment caused by position deviation and enable replacement at multiple stations. This allows some stations to unload or load materials while some stations are winding, reducing equipment idle time and achieving continuous production.
[0015] 2. By setting up a tensioning mechanism, compared with the existing technology, the third turntable drives the two rotating wheels to deflect, so that the two rotating wheels can adjust the tension of the copper wire between them, ensuring that the copper wire remains in a uniform tension state during the winding process, which helps to improve the winding quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] The embodiments disclosed in this application are as follows: Figure 1-6 The multi-station segmented stator core winding machine shown includes a base 1, a winding machine 2 installed on the top of the base 1, a wire outlet box 3 installed on one side of the winding machine 2, a tensioning mechanism installed inside the wire outlet box 3, and a replacement component installed on the top of the base 1.
[0026] The replacement components include a first servo motor 4, with a rotating plate 5 fixedly connected to the output end of the first servo motor 4, and a rotating ring 6 fixedly connected to the bottom end of the rotating plate 5. A groove 22 is provided on the upper surface of the base 1, with the inner side of the groove 22 slidably connected to the outer side of the rotating ring 6. Multiple second servo motors 7 are installed inside the rotating plate 5, with a first turntable 8 fixedly connected to the output end of the second servo motor 7. A first positioning ring 9 is fixedly connected to the top of the first turntable 8. Multiple support frames 10 are fixedly connected to the top of the rotating plate 5. A threaded rod 11 is rotatably connected inside the support frame 10, with a knob 12 fixedly connected to the top of the threaded rod 11. A movable plate 13 is threadedly connected to the outer side of the threaded rod 11. Two guide posts 23 are slidably connected inside the movable plate 13, and the guide posts 23 are fixedly connected to the inner side of the support frame 10. A second turntable 14 is rotatably connected to the bottom end of the movable plate 13, with a second positioning ring 15 fixedly connected to the bottom end of the second turntable 14. A stator core 16 is provided between the turntable 14 and the first turntable 8. One end of the stator core 16 is attached to the inner side of the first positioning ring 9. Then, the knob 12 is rotated so that the threaded rod 11 can drive the movable plate 13 through the thread to drive the second turntable 14 to press down the stator core 16. The two guide posts 23 can provide guidance for the movable plate 13. At the same time, the bottom end of the second turntable 14 and the second positioning ring 15 are aligned with the top end of the stator core 16, so that the second positioning ring 15 and the first positioning ring 9 can provide positioning for the installation of the stator core 16, which can reduce the winding misalignment caused by position deviation. The first servo motor 4 drives the rotating plate 5 to rotate the connecting shell 180°, which can alternately replace multiple stator cores 16 on both sides. This allows some stations to unload or load materials while some stations are winding, thereby achieving continuous production and improving production efficiency.
[0027] Reference Figure 6 and 7 As shown, the tensioning mechanism includes a wire outlet tube 17. Three connecting housings 18 are installed at the top of the wire outlet box 3. The wire outlet tube 17 extends through the wire outlet box 3 into the interior of the connecting housings 18. A third servo motor 19 is installed inside the connecting housings 18. A third turntable 20 is fixedly connected to the output end of the third servo motor 19. The third turntable 20 is rotatably connected to the interior of the connecting housings 18. Two rotating wheels 21 are rotatably connected to one side of the third turntable 20. The copper wire is passed between the two rotating wheels 21, and the third servo motor 19 drives the third turntable 20 to deflect the two rotating wheels 21, so that the two rotating wheels 21 can clamp the copper wire between them. This allows for the adjustment of the tension of the copper wire, ensuring that the copper wire remains in a uniform tension state during the winding process, which helps to improve the winding quality.
[0028] Working principle of this utility model: This utility model designs a multi-station segmented stator core winding machine, the specific structure of which is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation between various structures, when it is necessary to wind the stator core 16, the copper wire on the base 1 is first passed through the stator core 16 and wound between the two rotating wheels 21, extending from the inside of the outlet tube 17 to the outside. Then, the third servo motor 19 is started, and the third servo motor 19 drives the third turntable 20 to rotate, so that the third turntable 20 can drive the two wheels 21 to deflect. The deflection of the two rotating wheels 21 can clamp the copper wire, thereby making the tension of the copper wire tight, so as to facilitate the adjustment and control of the tension of the copper wire. The stator core 16 is placed on the first turntable 8, and one side of the stator core 16 is aligned with one side of the first positioning ring 9. Then, the knob 12 is rotated, causing the threaded rod 11 to rotate. The threaded rod 11 drives the movable disc 13 to move downward through the thread. Two guide posts 23 are slidably connected to the inner side of the movable disc 13, so that the two guide posts 23 can guide the movement of the movable disc 13. This allows the movable disc 13 to stably drive the second turntable 14 to press the top of the stator core 16, and to align the second positioning ring 15 with the stator core 8. The top edges of the stator core 16 are aligned, allowing the first positioning ring 9 and the second positioning ring 15 to position the stator core 16. The stator core 16 is then fixed in place by the downward pressure of the movable plate 13. Next, the first servo motor 4 is activated, driving the rotating plate 5 to rotate. The rotating plate 5 causes the rotating ring 6 to slide within the slide groove 22, allowing the rotating plate 5 to stably rotate the connecting housing 180°, thus rotating the multiple installed stator cores 16 to the front of the winding machine 2. Then, the base 1 is activated, allowing the winding to proceed. The tube 17 can wind copper wire around the outside of the stator core 16 and start the second servo motor 7. The second servo motor 7 drives the first turntable 8 to rotate. The second turntable 14 is connected to the inside of the movable plate 13, so that the first turntable 8 and the second turntable 14 can clamp and limit the stator core 16 while assisting in driving the stator core 16 to rotate. In cooperation with the base 1, three stator cores 16 can be wound at the same time. While three stator cores 16 are being wound, the other three stator cores 16 can be disassembled and replaced.
