[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 4 As shown, this embodiment provides a micro-motor rotor-stator insertion device, which includes: a base 1, a support plate 2, a first positioning platform 4, a second positioning platform 5, a first driving member 6, a second driving member 7, and a control system. The support plate 2 is fixedly mounted on the base 1, and a guide rail 3 is protruding from the support plate 2. The guide rail 3 extends vertically. The first positioning platform 4 is slidably mounted on the guide rail 3, and a first slot is recessed in the first positioning platform 4 for engaging the rotor 100. The second positioning platform 5 has a second slot for engaging the stator 200. The first driving member 6 is drivenly connected to the first positioning platform 4 and can drive the first positioning platform 4 to slide along the guide rail 3. The second driving member 7 is drivenly connected to the second positioning platform 5 and can drive the second positioning platform 5 to slide along the guide rail 3. Both the first driving member 6 and the second driving member 7 are communicatively connected to the control system. This configuration allows for pre-positioning of the rotor 100 and stator 200 in the vertical direction using the first positioning platform 4 and the second positioning platform 5, respectively, preventing skewness and ensuring that the rotor 100 is aligned before entering the stator 200. This effectively improves the assembly efficiency and quality of the rotor 100 entering the stator 200, and enhances the stability and reliability of the operation. At the same time, a control system is introduced to control the first drive component 6 and the second drive component 7 to achieve the rotor 100 entering the stator 200. Through independent dual-drive control, the relative movement of the rotor 100 and stator 200 is highly flexible, which can adapt to more complex process requirements, greatly improve the degree of automation, and reduce labor costs and labor intensity.

[0038] Furthermore, the inner wall of the second slot is provided with several strong magnetic blocks, which can attract and fix the stator 200 to ensure that it does not shift.

[0039] Optionally, the micro-motor rotor-to-stator device further includes a top plate 8, a push block 9, and a locking nozzle 10. The top plate 8 is fixedly connected to the top of the support plate 2. The output end of the first drive member 6 is drivenly connected to the push block 9, and the push block 9 is fixedly connected to the locking nozzle 10, which is used to lock the rotor shaft. With this configuration, the locking nozzle 10 can precisely clamp the rotor shaft. The first drive member 6 actuates to push the rotor 100 downward with extremely high coaxiality, smoothly inserting it into the stator 200 fixed by the second positioning table 5, further improving the stability and precision of the assembly process.

[0040] Optionally, the micro-motor rotor-stator feeding device further includes an elastic element 11 and a positioning rod 12. One end of the positioning rod 12 is fixedly connected to the first positioning platform 4, and the other end of the positioning rod 12 slides through the top plate 8. The elastic element 11 is sleeved on the positioning rod 12, and both ends of the elastic element 11 along its own length direction abut against the top plate 8 and the first positioning platform 4, respectively. Further, the elastic element 11 is a compression spring. This configuration, with the addition of the elastic element 11 and the positioning rod 12, creates a precise "flexible pressing" system. The positioning rod 12 ensures the precise guidance of the vertical movement of the first positioning platform 4, while the elastic element 11 forms a crucial buffer between the drive component and the positioning platform. Specifically, when the rotor 100 contacts the stator 200, the rigid thrust of the drive component is converted into a smooth, constant pressure applied by the elastic element 11, thereby effectively absorbing impact, automatically compensating for minor alignment deviations, and achieving overload protection. Ultimately, while ensuring high-precision assembly, it greatly reduces the risk of damage to the rotor 100 and stator 200 due to hard collisions, significantly improving the assembly yield and reliability.

[0041] Specifically, this embodiment provides the following technical solution by way of example: the micro motor rotor-to-stator device further includes a fixed base 13 and a connecting block 14. The fixed base 13 is fixedly connected to the top plate 8. The first driving member 6 is fixedly disposed on the fixed base 13, and the output end of the first driving member 6 is connected to the connecting block 14. The connecting block 14 is provided with a plurality of support columns 15, and the plurality of support columns 15 are all fixedly connected to the push block 9.

[0042] Optionally, the micro-motor rotor-stator device also includes several bearings 16, each corresponding to a specific support column 15. The outer ring of each bearing 16 is fixedly connected to the top plate 8, and the inner ring of each bearing 16 is fixedly connected to the support column 15. Furthermore, the bearings 16 are linear bearings. This configuration, introducing linear bearings, transforms the sliding friction contact between the support column 15 and the top plate 8 into rolling friction contact, thereby significantly reducing motion resistance, eliminating crawling, and achieving higher precision uniform linear motion. The low frictional resistance allows the first drive component 6 to start and stop more quickly, resulting in a more sensitive system response and improved assembly cycle time and efficiency.

[0043] Optionally, in order to achieve real-time monitoring and position feedback of key workstations and realize closed-loop control, thereby greatly improving the controllability, safety and reliability of the entire assembly process, the micro motor rotor-stator device also includes a photoelectric detection switch and a sensor assembly. The photoelectric detection switch is fixedly installed on the support plate 2 by the first fixing member 17, and the sensor assembly is fixedly installed on the top plate 8 by the second fixing member 18. Both the photoelectric detection switch and the sensor assembly are communicatively connected to the control system.

[0044] Optionally, in order to further avoid the second positioning stage 5 from deviating or other defects, the micro motor rotor entering the stator device also includes a limiting member 19. The limiting member 19 is fixedly connected to the second positioning stage 5, and the base 1 has a limiting slot hole, into which the limiting member 19 is inserted.

[0045] In this embodiment, both the first driving component 6 and the second driving component 7 are cylinders.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
