The equipment is mainly used for welding the side plate and end plate of power battery modules. The workflow of the equipment is as follows: the seven axis robot places the side plate, end plate, stacked battery cells, etc. into the welding slot, and the battery module automatically assembles, presses, positions, and welds. After the welding is completed, the seven axis robot grabs the welded module and puts it into the next workstation.

• The welding parameters corresponding to the module barcode, such as welding time, power, speed, servo parameters, etc., are saved locally and uploaded to the MES system

• Squeeze the end plate and battery cell with the reference edge, so that the total length of the module is controlled within ± 0.5mm, and the flatness between the end plate and the bottom of the battery cell is less than 0.3mm

• After welding, the surface is smooth and free from burning, and there is a nitrogen gas pressure flow detection and adjustment device.

• The laser adopts dual channel time-sharing light welding, namely YLS-6000-S2T
