Synchronous welding assembly of new energy battery shell

Abstract

A synchronous welding assembly of a new energy battery shell comprises a battery shell. The outer side of the battery shell is sleeved with two clamping mating pieces. An elastic mating piece is clamped between the clamping mating piece and the battery shell. The elastic mating piece is in interference fit with the battery shell. The clamping mating piece squeezes the elastic mating piece on the outer side of the battery shell through pressure, and the elastic mating piece is compressed to generate squeezing to the battery shell. The clamping mating piece comprises a lower support plate, and the lower support plate is provided with a locating portion corresponding to the elastic mating piece. The battery shell is sleeved with the elastic mating piece, and the battery shell and the elasticmating piece are limited and installed in the locating portion. The lower support plate is provided with an installation groove. The battery shell penetrates through and is inserted into the installation groove. According to the synchronous welding assembly of the new energy battery shell, the elastic mating piece and the clamping mating piece are arranged outside the battery shell, so that the elastic mating piece bears squeezing force and downward pressure force, and synchronous welding is conducted on the battery shell under the action of two kinds of force.

Description

Technical field [0001] The invention relates to a battery shell, in particular to a synchronous welding assembly of a new energy battery shell. Background technique [0002] Common battery shells are relatively thin, so the overlap of the upper and lower shells of the battery needs to be welded around. In this case, if pressure is applied in a single direction, it is easy to cause product deformation, and the amount of pressure applied will also affect the welding effect. [0003] Chinese Patent Document No. CN109346782A discloses a method for pressing a battery on 2019.02.15. The steps are as follows: Step 1. The pressing frame includes a U-shaped frame and a cover plate. The U-shaped frame includes a bottom plate and a bottom plate connected to the bottom plate. Flip the plate, and the flip plate is used to position the cover plate at different heights; step two, place multiple pole plates and multiple AGM diaphragms on the bottom plate alternately, and press the cover plate down...
