When the movable plate (306) moves, the elastic retractable clamp (307) is driven to move to adjust the position of the battery and apply slight pressure. Step 3: When the laser device (2) completes welding the battery, the telescopic device (301) is started again. When the telescopic device (301) is started, it drives the push platform (302) to move. When the push platform (302) moves, it drives the baffle (303) to move. When the baffle (303) moves, it drives the battery to leave the ladder platform (304).
