Multi-channel storage battery busbar welding machine

Abstract

The invention provides a multi-channel storage battery busbar welding machine which comprises a battery in-out conveying mechanism, a double-channel welding conveying mechanism, a positioning mechanism, a welding mold, an automatic wire feeding welding gun assembly, an X-direction translation assembly and a Y-direction translation assembly. Each conveying channel is provided with two busbar welding stations, each busbar welding station is provided with a positioning mechanism and a welding mold, the number of the automatic wire feeding welding gun assemblies is two, the automatic wire feeding welding gun assemblies are movably installed on the X-direction translation assembly, and the Y-direction translation assembly is used for controlling the automatic wire feeding welding gun assemblies to switch positions on the two conveying channels. The automatic wire feeding welding gun assembly comprises a wire feeding assembly and a welding gun assembly, and the welding gun assembly is used for conducting busbar welding on the battery tabs on the welding die. According to the welding machine, a multi-channel layout structure is adopted, the production efficiency is high, assembly line automatic operation can be achieved, and the labor cost is greatly reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of battery welding, in particular to a multi-channel battery bus bar welding machine. 【Background technique】 [0002] The welding of lead-acid batteries, especially the welding of busbars of lead-acid batteries for electric vehicles, refers to the process of melting the positive pole pieces in the battery pole group and the negative pole pieces of adjacent battery cells in series to realize the welding of the busbars. process. The earliest manual welding was adopted, and the tabs of the pole piece were melted after burning at high temperature with gas, and solder was added, and then cooled and formed to realize the welding of the busbar. With the improvement of automation level, the casting welding method is generally used in the market at present, with automatic or semi-automatic welding machines to realize the welding of battery busbars. The cast welding method is to heat and melt the alloy lead in a l...

AI Technical Summary

Problems solved by technology

[0003] The defects of manual gas welding mentioned above are: high labor intensity, poor welding environment, which is not conducive to the health of operators

Welding quality consistency is poor, battery quality controllability is poor

Automatic or semi-automatic casting welding also has the disadvantage of high labor intensity. At the same time, due to the constant heat preservation and heating of the lead liquid, the energy consumption is large and the welding cost is high.

The welding environment cannot be relatively isolated, and lead dust pollution is large, which affects the health of operators
