Description

[0001] The present invention relates to the technical field of welding equipment for energy storage battery side plates, and in particular to a side plate welding device and a welding method for energy storage battery production. Background Art

[0002] Energy storage batteries mainly refer to batteries used in solar power generation equipment, wind power generation equipment and renewable energy storage. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic waves. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space. When producing energy storage batteries, welding equipment is required to weld the side panels of the energy storage battery shell. Due to the thin thickness of the side panels, welding stress is easily generated during welding, which in turn causes welding stress deformation at the welding end of the side panels. Therefore, Patent Publication No. CN113909754A proposes "a side panel welding device for energy storage battery production", which delivers external cooling gas to the nozzle through an air pump, and then sprays the nozzle to the welding position of the side panel, thereby quickly cooling the welded side panel to avoid the deformation of the side panel caused by thermal stress during welding.

[0003] Since this solution cannot clean the surface of the side panel during welding, impurities such as rust and scale on the surface of the side panel will decompose and produce gas during welding, resulting in pores in the weld. The pores will reduce the density and strength of the weld, causing battery leakage, affecting the performance and safety of the battery. In view of the above reasons, the present application proposes a side panel welding device and welding method for energy storage battery production. Summary of the invention
