The detection tooling includes an upper fixing plate 1 and a lower rotating plate 2. The upper fixing plate 1 and the lower rotating plate 2 are connected by a rotating shaft. The diameter of the upper fixing plate 1 is smaller than that of the lower rotating plate 2. A camera support 3 is provided at the edge of the upper surface of the upper fixing plate 1, and a detection camera module 4 is provided on the camera support 3. A plurality of motor supports 5 are evenly arranged at the edge of the upper surface of the lower rotating plate 2, and motors 6 are provided on the motor supports 5. The lower rotating plate 2 can rotate, and the motors 6 can move to directly below the detection camera module 4 and the blanking tooling following the lower rotating plate 2.

[0019] In a further embodiment, the feeding tooling includes a vibrating bowl 7, a discharging plate 8 and a cutting component. There are two vibrating bowls 7, and eccentric wheels 18 are arranged inside the vibrating bowls 7. The discharging ports of the two vibrating bowls 7 are respectively connected to the two discharging plates 8. The cutting component is located at the other end of the discharging plate 8 and is close to the detection tooling. A bearing table 13 is arranged between the cutting component and the detection tooling. The cutting component includes an electric cylinder 9 and a cutting plate 10. The cutting plate 10 is arranged between the discharging plate 8 and the bearing table 13. The electric cylinder 9 is perpendicular to the discharging plate 8 and is horizontally connected below the cutting plate 10. The cutting plate 10 can be driven by the electric cylinder 9 to move between the ends of the two discharging plates 8.

[0020] In a further embodiment, referring to Figure 2 and Figure 3 ,the blanking tooling includes a blanking support 11, a translation electric cylinder 12 and a blanking component. The blanking support 11 is arranged outside the detection tooling and the feeding tooling. The translation electric cylinder 12 is arranged at the upper end of the blanking support 11. The blanking component is vertically arranged on the translation electric cylinder 12. The blanking component can be driven by the translation electric cylinder 12 to move above the bearing table 13 and the motor supports 5. The blanking component includes a blanking electric cylinder 14, a rotating electric cylinder 15, a jaw cylinder 16 and jaws 17. The blanking electric cylinder 14 is connected to the translation electric cylinder 12. The rotating electric cylinder 15 is connected to the lower end of the blanking electric cylinder 14. The jaw cylinder 16 is arranged below the rotating electric cylinder 15. The jaws 17 are connected to the lower end of the jaw cylinder 16. A force sensor 19 is arranged between the jaw cylinder 16 and the rotating electric cylinder 15.

[0021] In a further embodiment, the detection camera module 4 is connected to the rotating electric cylinder 15 through Ethernet and PLC communication. A detection camera, a camera lens and a light source are provided on the detection camera module 4. The jaws 17 and the eccentric wheels 18 perform profiling positioning so that the clamping angle of the jaws 17 is the same each time.

[0022] When the utility model is in use, two types of eccentric wheels 18 are respectively placed in two vibrating bowls 7. Each installation will select the type of eccentric wheel 18 according to needs. Then, the electric cylinder 9 will drive the cutting plate 10 to block the discharge plate 8 of the other eccentric wheel 18. The vibrating bowl 7 where the selected type of eccentric wheel 18 is located will neatly arrange the eccentric wheels 18 and convey them through the discharge plate 8 to the bearing platform 13 for waiting for assembly;

[0023] Then, the motor 6 is placed on the motor support 5, and the lower rotating plate 2 rotates. The motor 6 passes through the detection camera module 4. The detection camera identifies the position of the flat notch of the motor 6 and informs the rotating electric cylinder 15 of the identified flat angle through Ethernet and PLC communication. At this time, the translation electric cylinder 12 drives the press-fitting electric cylinder 14 to move above the bearing platform 13. The press-fitting electric cylinder 14 moves downward to make the clamping jaw 17 contact the eccentric wheel 18. Then, the clamping jaw cylinder 16 drives the clamping jaw 17 to clamp. Then, the press-fitting electric cylinder 14 moves upward. The translation cylinder 12 drives the clamping jaw 17 to move above the motor 6. The rotating cylinder 15 rotates according to the received angle to make the angle of the mounting hole on the eccentric wheel 18 the same as the flat angle of the motor shaft of the motor 6. Then, the press-fitting electric cylinder 4 moves downward for the assembly of the eccentric wheel 18;

[0024] During assembly, the force sensor 19 monitors the press-fitting pressure, mainly detecting the pressure when the eccentric wheel 18 contacts the motor shaft and the pressure at the final position. When the eccentric wheel 18 contacts the motor shaft, if it is detected that the pressure exceeds the normal range, it indicates that there is a deviation in the angle detected by the camera, and the press-fitting is stopped, and this product is treated as an NG product; if the pressure is within the reasonable range during contact, it indicates that the angle is correct, and the press-fitting electric cylinder 4 continues to press down until the final position. At the same time, it monitors whether the pressure at the final position is within the normal range. If it is, it is a qualified product. If it exceeds the normal range, it is treated as an NG product;

[0025] When it is necessary to switch the type of eccentric wheel 18, only the position of the cutting plate 10 needs to be moved, and by repeating the above steps, the assembly of all products can be completed.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
