Novel aluminum-palladium welding jig for square battery pack

Abstract

The invention relates to a novel square battery pack aluminum-palladium welding jig which comprises a jig body, first fixing clamping seats and second fixing clamping seats, limiting grooves are formed in the periphery of the jig body, and one first fixing clamping seat and three second fixing clamping seats are installed in the four limiting grooves correspondingly. A welding groove for limiting aluminum palladium is formed in the jig main body; the first fixing clamping seat and the second fixing clamping seat can effectively limit relative movement of the battery pack and the jig, the lower surface of the jig is consistent with the positive and negative electrode surfaces of the battery pack, aluminum palladium movement is limited most effectively, the safety performance is high, and the insulating property is good; the material can prevent a welded battery pack from being damaged due to faults of a welding machine, the material is a flame-retardant material, the efficiency is high, the error-tolerant rate is high, and the conditions such as pseudo soldering in the welding process can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of battery pack processing, in particular to a novel aluminum-palladium welding fixture for square battery packs. Background technique [0002] The square aluminum shell jig generally has its own characteristics. When the aluminum palladium welding is performed on the 12.8V400AH square aluminum shell battery pack, the existing welding jig is complicated to operate, and cannot limit and fix the aluminum palladium and the battery pack, resulting in welding. During the process, the aluminium and palladium moved, which in turn led to deviations in the welding work, resulting in property damage. SUMMARY OF THE INVENTION [0003] The problem solved by the present invention is to provide a new aluminum-palladium welding jig for a square battery pack, which can effectively improve the welding quality and speed. Compared with the traditional jig, the operation is simple, the fault tolerance rate of the work operati...
