[0043] In actual use, one end of the relay punch mounting plate 101 is sent onto the No. 1 conveyor line 1, and the driving component 108 drives the No. 1 rotating shaft 102 to rotate, so that the No. 1 rotating shaft 102 drives the driving wheel 104 to rotate, so that the belt 106 and the driven wheel 105 rotate synchronously, so that the relay follows the belt 106 and moves synchronously to the other end of the mounting plate 101. At this time, the pin of the relay is located below between the two belts 106.

[0044] In the above design, the specific setting and implementation of the No. 1 conveyor line 1 facilitate the conveyance of the relays, and the steps can ensure that the relays will not fall during conveyance, which is convenient for guiding.

Then the No. 1 slide cylinder 429 is reset, and the No. 1 multi-axis cylinder 432 drives the pressure plate to press down, so that the No. 1 pressure plate 433 applies pressure to the relay, and the No. 1 elastic support 425 contracts, and the relay then presses down the No. 1 step 42601070, so that the No. 1 horizontal plate 422 is pressed down and slides relative to the No. 1 column 424, so that the pin of the relay contacts the No. 1 probe 435 on the No. 1 mounting block 434 to complete the electrical connection, and then the withstand voltage tester 41 displays the leakage value, and the withstand voltage performance of the relay is determined by the leakage value.
