Abstract

The invention belongs to the technical field of laser welding, and relates to a pressing cylinder structure and laser welding equipment. The laser welding device is applied to laser welding of a power battery module and comprises a first pressing cylinder, a cover plate and a second pressing cylinder. The second pressing cylinder is arranged at the bottom of the first pressing cylinder, an air inlet is formed in one side of the first pressing cylinder, the cover plate is arranged on the side, located on the air inlet, of the first pressing cylinder, and an air channel is formed among the first pressing cylinder, the cover plate and the second pressing cylinder. The air channel is communicated with the air inlet, air outlets are formed in the lower end of the first pressing cylinder and the lower end of the second pressing cylinder, the air inlet is used for blowing in protective gas, and the protective gas passes through the air channel and is blown out of the air outlets. The shielding gas can cover each welding area more uniformly, so that each welding area is protected more comprehensively, the situations that a welding object splashes and the surplus height of a welding seam is too high during welding are well reduced, the welding effect is improved to a great extent, and the welding object is more attractive after being welded.

Description

technical field

[0001] The present application relates to the technical field of laser welding, and more specifically, relates to a pressure cylinder structure and laser welding equipment. Background technique

[0002] The function of the Busbar (bus bar, bus bar) of the power battery module is mainly to realize the electrical connection between the battery cells. At present, the laser welding of the Busbar of the power battery module generally has unsatisfactory welding surface effects, such as excessive weld reinforcement, severe welding spatter, etc. In order to obtain a good welding effect, the use of a ring spot laser can also make The welding effect has been improved, but the cost of the ring spot laser is much higher than that of the traditional spot laser. Therefore, it is necessary to develop a pressure cylinder structure that attaches the Busbar to the pole of the power battery module and protects the position of the welding seam through shielding gas.
