[0033] In this embodiment, the support frame is arranged above the PACK box, and a first rack transmission mechanism is arranged on the side beam of the support frame. The first rack transmission mechanism is driven by an X-axis servo motor 1. First transmission gears are arranged at both ends of the beam. The gear and rack cooperate to drive the beam to move on the side beam of the support frame to adjust the beam to a suitable position above the PACK box.

[0034] In the specific implementation, in order to improve the stability and ensure the safety and reliability of the device, the crossbeam is a rectangular frame structure, and the second rack transmission mechanism is respectively arranged on the two opposite side beams of the frame, and the second rack transmission mechanism is driven by the Y-axis servo motor 2; the two second rack transmission mechanisms are respectively arranged with load-bearing slides, and the inner side walls of the two load-bearing slides are respectively arranged with two second transmission gears adapted to the second rack transmission mechanism, and the outer side walls of the two load-bearing slides are respectively arranged with vertical driving devices.

[0037] The batteries in multiple rows and columns are pressurized and shaped in three directions: length, width and height, to meet the dimensional requirements of battery products in all directions. Visual positioning is used to ensure that the batteries are accurately placed in the PACK box.

[0038] On the opposite side of the above-mentioned pressurizing mechanism, a reference device is set to provide a pressurizing reference to ensure the reference position of the battery product.
