[0083] The process of detecting the motor shell A is as follows: when the conveying position sensor detects that the tray 7 with the riveting completed motor shell A moves to the detection position, the conveying limiting block blocks the tray 7, the insulating bracket moves upward under the action of the insulating cylinder 304, lifts the tray 7 from the conveying belt 6, and separates from the contact with the conveying track 61, so that the positive probe 301 and the negative probe 302 are connected with the positive and negative of the resistance tester respectively, the resistance test circuit is turned on, the resistance test is completed, the test result is recorded, and the motor shell A is recorded, so that the qualified and unqualified motor shell A is placed on the finished product table 4 at different positions by the subsequent jaw motor, after the test is completed, the insulating bracket is reset, the conveying limiting block is reset, the tray 7 is in contact with the conveying track 61 and moves along with the conveying track 61.

[0084] The process of moving the tray 7 on the conveying track 61 and the return track 62 is as follows: when the tray 7 moves from the assembly table 1 to the finished product table 4, the moving position sensor detects that the tray 7 arrives, the conversion hook 637 hooks the tray 7 at the tail of the conveying track 61, then the conversion push-pull cylinder 635 drives the conversion push-pull plate 634 and the conversion hook 637 to move, and drives the tray 7 to move to the conversion lifting frame 631, then the conversion lifting cylinder 632 drives the conversion push-pull cylinder 635 and the tray 7 to move up and down, when the tray 7 moves to the head of the return track 62, the conversion push-pull cylinder 635 pushes the conversion push-pull plate 634 and the tray 7 to move to the head of the return track 62, when the tray 7 moves to the head of the return track 62, the conversion hook 637 releases the hooking of the tray 7, and the tray 7 moves under the action of the return track 62 and returns to the assembly table 1, thereby completing the reversing of the tray 7 movement and realizing the reversing automation.

[0085] The process of transferring the motor shell A between the assembly table 1, the conveying track 61, the riveting limiting column 205 and the finished product table 4, and the tray 7 between the conveying track 61 and the return track 62 is as follows: the conveying position sensor is used to detect whether the motor shell A reaches the designated position, and then the conveying limiting block is used to limit the tray 7 with the motor shell A, so that it stops moving along with the conveying track 61, and facilitates the clamping, transferring and detecting of the motor shell A.
