The straight-line type spot welding machine of the capacitor battery has the advantages of high production efficiency, simple structure, stability in operation, complete full-automatic production and the like.

Description

technical field [0001] A linear spot welder for a capacitor battery belongs to the field of water system square power battery manufacturing equipment, and in particular relates to a linear spot welder for a capacitor battery for welding pole pieces of a water system square power battery to lugs. Background technique [0002] Traditional battery pole piece spot welding requires manual operation, which is very inefficient, not only increases labor costs, but also has a high scrap rate, and the welding edge of the pole piece is prone to re-contamination. [0003] In response to the above situation, people have invented a variety of pole piece spot welding machines and applied them to actual production, effectively reducing labor costs and scrap rates. However, most of the pole piece spot welding machines still have the following problems: 1. The production efficiency is still low. It does not meet the actual requirements, the structure is complex, and the conveying of the pole ...

AI Technical Summary

Problems solved by technology

[0002] The traditional spot welding of battery pole pieces requires manual operation, the efficiency is very low, not only increases the labor cost, but also has a high scrap rate, and the welding edge of the pole piece is easy to be polluted again

[0003] In response to the above situation, people have invented a variety of pole piece spot welders and applied them to actual production, effectively reducing labor costs and scrap rates. However, most of the pole piece spot welders still have the following problems: 1. The production efficiency is still low. It does not meet the actual requirements, the structure is complicated, and the conveying of the pole piece is not in a straight line, so that the transmission mechanism in at least two directions needs to interact to complete the feeding and discharging of the pole piece, resulting in a waste of time for the pole piece transmission. Only one pole piece can be transported and spot welded at a time; 2. It is necessary to manually stack many pole pieces neatly and place them on the pole piece spot welding machine, which will easily cause secondary pollution on the welding edge of the pole pieces and affect the quality of subsequent seam welding; 3. , The pole pieces are stacked together after the spot welding is completed, and the stacking of the pole pieces before and after spot welding is easy to cause damage to the pole pieces
