The invention belongs to the technical field of new energy vehicle power battery manufacturing equipment, and in particular relates to a pressing device for nanosecond laser welding. It includes a frame, and an assembly line groove is arranged on the frame, and a plurality of rolling wheels are arranged side by side in the assembly line groove, and a battery module placement plate is arranged on the rolling wheel, and a bracket is installed on the top of the frame, and a number of the brackets are fixed. Cylinder, the piston end of the cylinder extends to the battery module placement plate, the piston end fixes the lifting plate, the width of the lifting plate is equal to the width of the battery module, and several avoidance grooves are set on the bottom surface of the lifting plate, so The avoidance slots correspond one-to-one to the positions of the battery tabs of the battery module. The invention replaces the manual operation, and the automatic pressing driven by the cylinder can make the conductive copper plate have the same pressing height, so as to ensure reliable welding and stable quality during welding.
Description
technical field [0001] The invention belongs to the technical field of new energy vehicle power battery manufacturing equipment, and in particular relates to a pressing device for nanosecond laser welding. Background technique [0002] When assembling the pouch battery packaged with aluminum-plastic film, it is necessary to weld the tabs of the battery to the conductive copper plate. The traditional process adopts the method of manual operation to bend the tabs and weld them to the conductive copper plate. Due to the manual operation, the height of the conductive copper plate is not uniform, and it is easy to weld perforation during welding, resulting in unstable welding quality. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a pressing device for nanosecond laser welding with automatic pressing, uniform pressing height and stable and consistent welding quality. [0004] In order to achieve the above object, ...
