Problems solved by technology
The traditional process adopts the method of manual operation to bend the tab and weld it with 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.

The invention belongs to the technical field of new energy automobile power battery manufacturing equipment and particularly relates to a nanosecond laser soldering pressing device which comprises a rack. The rack is provided with assembly line grooves. A plurality of rollers are parallelly arranged in each assembly line groove. A battery module holding plate is arranged on the rollers. The top end of the rack is provided with brackets. A plurality of cylinders are fixed to the brackets. The piston ends of the cylinders stretch towards the battery module holding plate. Lifting plates are fixed to the piston ends and are as wide as battery modules. The bottom faces of the lifting plates are provided with a plurality of avoiding grooves which correspond to battery cell tabs of the battery modules in a one-to-one mode. Manual operation is replaced by the nanosecond laser soldering pressing device, and automatic pressing is driven by the cylinders so that the pressing heights of conductive copper plates are consistent, and reliable soldering and stable quality are ensured during soldering.
Description
Technical field [0001] The invention belongs to the technical field of new energy vehicle power battery manufacturing equipment, and specifically relates to a pressing device for nanosecond laser welding. Background technique [0002] When assembling a soft-pack battery encapsulated with aluminum-plastic film, the tabs of the battery need to be welded to the conductive copper plate. The traditional process uses manual operation to bend the tabs and weld them with the conductive copper plate. Due to the inconsistent height of the conductive copper plate during manual operation, it is easy to weld and perforate during welding, resulting in unstable welding quality. Summary 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 objectives, the present invention i...
