[0069] S3, then the battery is transferred to the barcode pasting mechanism by the robot arm 2, and the barcode 705 is pasted on the surface of the aluminum shell 704 to mark the identity information;

[0070] S4, then the battery is moved to the flipping and reversing mechanism by the robot arm 2, and the battery is reversed by the flipping and reversing mechanism;

[0071] S5. Finally, the battery is folded back by the second robot, and the insulating paper 703 on the other side of the battery is pasted, and the aluminum shell 704 on the other side is assembled, thereby completing the automatic packaging of the block battery module; the entire mechanism is installed on the 8th surface of the workbench, and each mechanism is connected and installed together, and each completes the corresponding action task. Each step is simple, ingenious, efficient and orderly; the loading of block batteries from other places to the belt 103 and the completion of unloading are all completed by the robot.
