[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 2 The utility model provides an embodiment: a motor rotor insulation layer coating device, including a machine platform 1, the four corners of the bottom end of the machine platform 1 are fixedly connected with machine feet, the machine feet here play a supporting role for the machine platform 1, the top of the machine platform 1 is fixedly connected with a support ring 2, the middle of the top of the machine platform 1 is fixedly connected with a servo motor 3, the driving end of the servo motor 3 is fixedly connected with a main shaft, and the servo motor 3 here will drive the main shaft to rotate when rotating.

[0027] Reference Figure 2 The outside of the main shaft is fixedly connected to the inner wall of the pressure block 6, and the two ends of the outside of the main shaft are fixedly connected to the shell 4. When the main shaft rotates, it will drive the shell 4 to rotate together. The bottom end of the shell 4 is rotatably connected to the top of the support ring 2, and the top of the shell 4 is rotatably connected to the threaded rod 5. The outside of the threaded rod 5 is threadedly connected to the pressure block 6. Twisting the threaded rod 5 here will drive the pressure block 6 to move up and down. The outside of the pressure block 6 is slidably connected to the inner wall of the shell 4, and multiple rotor bodies 7 are slidably connected to the four sides of the shell 4.

[0028] Reference Figure 1-Figure 2 When the pressing block 6 descends, it will press the inserted rotor body 7 to prevent it from being thrown out during the coating process. The bottom end of the pressing block 6 contacts the top of the inner wall of the rotor body 7. The top of the machine table 1 is fixedly connected with a lifting assembly, and the lifting assembly here is used to control the subsequent coating device. The lifting assembly includes a support frame 8, and the bottom end of the support frame 8 is fixedly connected to the top of the machine table 1. The top of the inner wall of the support frame 8 is fixedly connected with a hydraulic rod 9. The front and rear sides of the top of the inner wall of the support frame 8 are fixedly connected with telescopic rods 11. The support frame 8 here provides stable support for the telescopic rod 11.

[0029] Reference Figure 1 and Figure 3 The bottom end of the telescopic rod 11 is fixedly connected to a limit block 16, the bottom end of the limit block 16 contacts the top end of the shell 4, and the top end of the limit block 16 contacts the top end of the inner wall of the protective cover 14. The limit block 16 here ensures that the telescopic rod 11 will not leave the range of motion of the protective cover 14, and will keep it moving up and down in a straight line without deviation. The driving end of the lifting assembly is fixedly connected to the barrel 10, and a feed port 22 is opened on the right side of the top end of the barrel 10. The feed port 22 here is used to pour the coating liquid.

[0030] Reference Figure 1 and Figure 4The left and right sides of the bottom end of the barrel 10 are fixedly connected with an infusion tube 12, and the infusion tube 12 here is used to transport the coating liquid. The inner wall of the infusion tube 12 is fixedly connected with a nozzle 13, and the external threads of the two nozzles 13 are connected with a protective cover 14. The nozzle 13 here can spray the coating liquid to coat the rotor body 7, and the protective cover 14 here prevents the coating liquid from splashing and prevents environmental pollution. The bottom end of the protective cover 14 is in contact with the top of the machine 1.

[0031] Reference Figure 3-Figure 5 The outside of the telescopic rod 11 is slidably connected to the inner wall of the protective cover 14, and the left and right sides of the inner wall of the protective cover 14 are fixedly connected with side blocks 15. The outside of the nozzle 13 is rotatably connected to the inner wall of the side block 15. The side block 15 here provides additional support for the nozzle 13 to make it more stable. The inside of the nozzle 13 is fixedly connected with an anti-blocking component, and the anti-blocking component includes two support blocks 17. The anti-blocking component here is used to prevent the coating liquid from being blocked in the nozzle 13, and the bottom end of the support block 17 is fixedly connected to the bottom end of the inner wall of the nozzle 13.

[0032] Reference Figure 5 The top ends of the two support blocks 17 are fixedly connected with a rotating column 18, and the support blocks 17 here provide stable support for the rotating column 18. The external rotation of the rotating column 18 is connected with a spiral blade 19. When the coating liquid flows through, it will drive the spiral blade 19 to rotate. After the spiral blade 19 rotates, it will in turn assist the coating liquid to prevent it from being blocked. The right side of the inner wall of the nozzle 13 is fixedly connected with a frame 20, and the inner wall of the frame 20 is fixedly connected with a filter screen 21. The filter screen 21 here is used to filter impurities in the coating liquid to prevent it from affecting the coating process.

[0033] Working principle: When using this device, the staff can first place the rotor body 7 to be coated in the holes around the shell 4, and then twist the threaded rod 5. At this time, the threaded rod 5 will drive the pressure block 6 inside the shell 4 to move up and down, and the block at the bottom will gradually press the tail end of the rotor body 7 to prevent it from slipping, and then start the servo motor 3. The support ring 2 here plays a role in supporting the shell 4 to keep it stable during rotation.

[0034] Then start the hydraulic rod 9, and the telescopic rod 11 here will extend and retract up and down with the hydraulic rod 9. At this time, the hydraulic rod 9 will drive the protective cover 14 at the bottom to descend until it completely covers the shell 4, and then fill the coating liquid into the feed barrel 10 from the feed port 22. At this time, the coating liquid will flow along the infusion tube 12 into the nozzle 13. The side block 15 here plays a supporting role, and the limit block 16 here limits the range of motion of the telescopic rod 11 so that it will not be separated from the protective cover 14.

[0035] After flowing into the nozzle 13, it will be further sprayed out from the nozzle of the nozzle 13 to coat the surface of the motor rotor. Because the shell 4 is rotating with the motor rotor around it at this time, the coating effect can be guaranteed to be complete and uniform. The frame 20 in the nozzle 13 here serves to fix the filter 21, and the filter 21 can block impurities in the coating liquid. The spiral blade 19 here will rotate under the support of the support block 17 and the rotating column 18 to ensure the circulation of the coating liquid and prevent blockage.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
