Technical Field

The invention relates to the technical field of welding devices, in particular to a welding jig and a using method thereof.

Background

New energy vehicles have become an integral trend of automobile industry development, and most of the new energy vehicles are pure electric vehicles or hybrid electric vehicles which adopt lithium batteries as electric energy storage devices. Due to the characteristics of lithium batteries, hard-shell batteries with steel shells, aluminum shells and plastic shells generally have potential safety hazards of explosion. The soft package battery has the advantages of high safety, high energy density, long service life and the like, and gradually replaces a hard shell battery.

In the production manufacturing process of the laminate polymer battery module, the high-voltage electric connection inside the laminate polymer battery module is required to be realized through a laser welding mode. In order to ensure the laser welding effect, the soft package battery module is firstly installed in a welding jig before welding; then compressing the electrode lug of the battery core of the battery module through a welding jig to ensure that the electrode lug is tightly contacted with the busbar; and finally, welding can be carried out. The welding equipment in the step is long in halt waiting time, so that resource waste is caused, the production cost is high, and the welding efficiency is low.

In view of the above problems, a welding jig and a method for using the same are needed to solve the above problems.
