DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] See Figures 1 to 5, the blanking and screening device for the stator and rotor cores of new energy vehicles involved in the present utility model includes a mounting plate 1.

A first bearing 6 is fixedly connected to the surface of the U-shaped column 5. Both the front and rear sides of the first U-shaped plate 2 are in contact with the surface of the first bearing 6. Through the first bearing 6, the second U-shaped plate 4 moves more smoothly left and right. A cross plate 7 is fixedly connected to the bottom of the second U-shaped plate 4. A first electric push rod 8 is fixedly connected to the bottom of the cross plate 7. A first hollow cylinder 9 is fixedly connected to the bottom of the first electric push rod 8. The first hollow cylinder 9 is controlled to move up and down by the first electric push rod 8. An electromagnet 10 is fixedly connected to the bottom of the inner wall of the first hollow cylinder 9. After the first hollow cylinder 9 is located above the stator and rotor cores, the stator and rotor cores can be fixed on the first hollow cylinder 9 by the suction force of the electromagnet 10. A controller 11 is fixedly connected to the left side of the first U-shaped plate 2. The moving mechanism 3, the first electric push rod 8, and the electromagnet 10 are all electrically connected to the controller 11. The controller 11 is used to receive signals from the detection device and control the operation of the moving mechanism 3, the first electric push rod 8, and the electromagnet 10.

[0022] Further, the moving mechanism 3 includes a driving motor 3.1. The bottom of the driving motor 3.1 is fixedly connected to the upper surface of the first U-shaped plate 2. The output end of the driving motor 3.1 is fixedly connected to a threaded column 3.2. A threaded sleeve 3.3 is threadedly connected to the surface of the threaded column 3.2. First connecting blocks 3.4 are fixedly connected to both the surface of the threaded sleeve 3.3 and the inner wall of the second U-shaped plate 4. A second bearing 3.5 is fixedly connected to the surface of the threaded column 3.2. Second connecting blocks 3.6 are fixedly connected to both the surface of the second bearing 3.5 and the upper surface of the first U-shaped plate 2. When the driving motor 3.1 drives the threaded column 3.2 to rotate, through the cooperation of the threaded column 3.2 and the threaded sleeve 3.3, the second U-shaped plate 4 can move left or right.

[0023] Further, a guiding column 12 is fixedly connected to the upper surface of the first hollow cylinder 9. Hollow blocks 13 are fixedly connected to both the front and rear sides of the second U-shaped plate 4. The inner wall of the hollow block 13 is in contact with the surface of the guiding column 12.

[0024] Further, a connecting frame 14 is fixedly connected to the left side of the inner wall of the first U-shaped plate 2. A second hollow cylinder 15 is fixedly connected to the right side of the connecting frame 14. An iron block 16 is fitted in the inner wall of the second hollow cylinder 15. A limiting ring 17 is fixedly connected to the surface of the iron block 16. The bottom of the limiting ring 17 is in contact with the upper surface of the second hollow cylinder 15. The iron block 16 is supported by the limiting ring 17. Pressing brackets 18 are fixedly connected to both the left side of the limiting ring 17 and the left side of the inner wall of the first U-shaped plate 2.

[0025] Furthermore, the pressing support 18 includes a second electric push rod 18.1. The left side of the second electric push rod 18.1 is fixedly connected to the left side of the inner wall of the first U-shaped plate 2. A third connecting block 18.2 is fixedly connected to the bottom of the second electric push rod 18.1. A spring 18.3 is fixedly connected to the bottom of the third connecting block 18.2. Connecting plates 18.4 are fixedly connected to both the bottom of the spring 18.3 and the left side of the limiting ring 17. The compression degree of the spring 18.3 between the third connecting block 18.2 and the connecting plate 18.4 is adjusted by the second electric push rod 18.1. By adjusting the compression degree of the spring 18.3, the resistance suffered by the iron block 16 when moving upward is changed. At the same time, through the cooperation of the connecting frame 14, the second hollow cylinder 15, the iron block 16, the limiting ring 17 and the pressing support 18, after the electromagnet 10 is opened and moves above the iron block 16, by observing whether the second electric push rod 18.1 can drive the iron block 16 to move upward, it can be judged whether the suction force of the electromagnet 10 is normal. Furthermore, the blanking and screening device has the function of automatically detecting the suction force of the electromagnet 10, thus making it more convenient for the user to repair the electromagnet 10.

[0026] Furthermore, a rubber pad 19 is bonded to the bottom of the first hollow cylinder 9. The first hollow cylinder 9 is separated from the stator-rotor core through the rubber pad 19. Thus, when the first hollow cylinder 9 approaches the stator-rotor core, the top of the stator-rotor core will not be damaged due to impact.

[0027] The working principle of the blanking and screening device for the stator and rotor cores of new energy vehicles of the present utility model is as follows: When the control unit receives the signal transmitted by the detection device, it controls the operation of the driving motor 3.1 through the controller 11, and drives the threaded column 3.2 to rotate through the driving motor 3.1. Then, through the cooperation of the threaded column 3.2 and the threaded barrel 3.3, the first hollow cylinder 9 is moved above the stator and rotor cores, and through the first electric push rod 8, the rubber pad 19 is brought into contact with the top of the stator and rotor cores. Then, the electromagnet 10 is turned on through the controller 11. At this time, through the suction force of the electromagnet 10 on the stator and rotor cores, the stator and rotor cores are fixed on the first hollow cylinder 9, and through the first electric push rod 8, the stator and rotor cores are lifted by a certain distance. Then, the controller 11 controls the driving motor 3.1 to rotate forward or backward according to the received signal, and through the cooperation of the threaded column 3.2 and the threaded barrel 3.3, the stator and rotor cores are moved to the OK conveyor line or the NG conveyor line. When the stator and rotor cores are moved to the designated position, the electromagnet 10 is turned off to separate the stator and rotor cores from the first hollow cylinder 9. When detecting the suction force of the electromagnet 10, first, through the cooperation of the driving motor 3.1, the threaded column 3.2 and the threaded barrel 3.3, the electromagnet 10 is moved above the iron block 16, and through the first electric push rod 8, the rubber pad 19 is brought into contact with the first hollow cylinder 9. Then, through the second electric push rod 18.1, the compression degree of the spring 18.3 between the third connecting block 18.2 and the connecting plate 18.4 is adjusted, and by adjusting the compression degree of the spring 18.3, the resistance suffered by the iron block 16 when moving upward is changed. When the resistance of the iron block 16 is adjusted, the electromagnet 10 is turned on, and the electromagnet 10 is controlled to move upward through the first electric push rod 8. At this time, by observing whether the iron block 16 moves upward, it can be judged whether the suction force of the electromagnet 10 is normal.

[0028] In addition, it should be noted that the above specific implementation manner is only an optimized solution of this patent. Any modification or improvement made by those skilled in the art according to the above conceptions is within the protection scope of this patent.
