When the photoelectric sensor detects that there is a carrier plate 1 at the designated position, the conveying line 2 stops conveying the carrier plate 1. When the carrier plate 1 is detected again, the conveying direction is changed. The carrier plate 1 starts to load the battery module from the right end of the conveying line 2 and is conveyed to the left end. When the carrier plate 1 is conveyed to the top of the lifting mechanism 3, the photoelectric sensor at the left end of the conveying line 2 detects that there is a carrier plate, and the conveying line 2 stops moving. The lifting mechanism 3 lifts the carrier plate 1 to the flipping position of the flipping mechanism 4, and then the flipping mechanism 4 moves inward to clamp the battery module on the carrier plate 1. After clamping, the lifting mechanism 3 lowers the carrier plate 1 by one end, and the flipping mechanism 4 flips the clamped battery module 180°. After flipping, the lifting mechanism 3 lifts the carrier tray 1 to the flipping position of the flipping mechanism 4 again, the flipping mechanism 4 releases the flipped battery module to the carrier tray 1, the lifting mechanism 3 puts the carrier tray 1 back on the conveying line 2 steadily, the photoelectric sensor at the left end of the conveying line 2 detects the carrier tray 1 again, and then conveys the carrier tray 1 to the right in the opposite direction; the carrier tray 1 is conveyed to the material picking and discharging position at the right end of the conveying line 2, the robot takes away the flipped battery module on the carrier tray 1, and moves the new battery module to the carrier tray 1, which is then conveyed to the left end by the conveying line 2 to be flipped.
