Abstract

The invention discloses a spot welding device for a power battery pack electrode slice. The spot welding device comprises a conveying assembly, two spot welding assemblies and a moving assembly, wherein the conveying assembly comprises a conveying rail and a first driving part used for driving the conveying rail to slide along the X axis of a rack; a conveying space for allowing a spot welding jigto be embedded in a sliding manner is formed in the conveying rail; a preparation station, a spot welding station and a finish station are sequentially arranged in the conveying space in the conveying direction of the spot welding jig; the two spot welding assemblies are arranged on the rack and are positioned on the two sides of the spot welding station of the conveying rail; the spot welding assemblies comprise spot welding heads, second driving parts used for driving the spot welding heads to slide along the Y axis of the rack, and third driving parts used for driving the spot welding heads to slide along the Z axis of the rack; and the moving assembly is arranged on the conveying assembly, and is used for conveying the spot welding jig between the preparation station and the spot welding station and between the spot welding station and the finish station along the conveying space. The main point of the technical scheme is that spot welding efficiency is high.

Description

technical field [0001] The invention relates to the technical field of spot welding equipment, in particular to a spot welding equipment used for electrode sheets of power battery packs. Background technique [0002] The power battery is the power source that provides the power source for the tool, and mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. With the rapid development of electronics, communication and other technical fields, large and medium-sized battery packs are used more and more widely. During the production process of large and medium-sized battery packs, spot welding operations must be performed on the electrode sheets of power battery packs. [0003] At present, most of the power battery pack electrodes are manually picked up by the power battery pack and manually welded. The welding is labor-intensive and the welding efficiency is low, so there are certain improvements. Contents of...
