The drive lifting cylinder 71 drives the sliding cylinder 72 to move upward, so that the dial 73 moves the sensor into the transfer seat 44, which facilitates the transfer of the sensor into the transfer seat 44.

[0050] Reference Figure 1 , Figure 2 and Figure 3 As shown, during the sensor transfer process, the electric slide rail 51 drives the lifting cylinder 52 to slide to the sensor placement location.

Multi-angle and multi-camera detection improves the accuracy of detection.

[0054] The implementation principle of the washing machine sensor coil welding status detection device in this application is as follows:

[0055] When sensors need to be sorted, the electric slide rail 51 drives the lifting cylinder 52 to slide to the sensor placement location. The lifting cylinder 52 is then moved to a suitable position where the suction head 53 holds the sensor. The electric slide rail 51 then drives the suction head 53 to slide onto the transport seat 55. A pressure plate moves the sensor from the suction head 53 onto the clamp 56. The sensor on the clamp 56 is then transferred to the transfer seat 44 via the transfer bracket 73. During this process, cameras 31, 32, 34, and 36 determine the quality of the sensors. If the sensor is qualified, the sliding plate 43 moves the transfer seat 44. Above conveyor belt 41, the drive cylinder 46 moves the push frame 45 to the material passage hole 431, causing the sensor inside the push frame 45 to fall onto conveyor belt 41. Conveyor belt 41 then transports qualified sensors. If the sensor is defective, the sliding plate 43 moves the transfer seat 44 above conveyor belt 42, and the drive cylinder 46 moves the push frame 45 to the material passage hole 431, causing the sensor inside the push frame 45 to fall onto conveyor belt 42. Conveyor belt 42 then transports defective sensors, facilitating automatic classification of the tested sensor coils and saving manpower.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
