Battery automatic loading and unloading laser welding machine

Abstract

The invention discloses a battery automatic loading and unloading laser welding machine which comprises a machine table base, a loading / receiving mechanism, a battery core transporting mechanism, a battery core pre-positioning mechanism and a battery core positioning clamping mechanism. The machine table base is used for installing the loading / receiving mechanism, the battery core transporting mechanism, the battery core pre-positioning mechanism and the battery core positioning clamping mechanism. The battery automatic loading and unloading laser welding machine mainly comprises the machine table base, the loading / receiving mechanism, the battery core transporting mechanism, the battery core pre-positioning mechanism and the battery core positioning clamping mechanism, full-automatic loading and unloading can be achieved, and the function of being changed into circumferential weld at one time is achieved. The battery automatic loading and unloading laser welding machine can solve theproblems that in the battery core welding process, the battery core manual placement efficiency is low and manual work is wasted, solves the problem that the battery core manual overturning efficiencyis low, and solves the problem that the distance between a laser head at the square battery core circumferential weld circular bead position and a welding point is changed.

Description

technical field [0001] The invention relates to battery processing equipment, in particular to a battery automatic loading and unloading laser welding machine. Background technique [0002] At present, in the manufacturing process of lithium-ion aluminum shell cells, it is necessary to use side welding to weld the aluminum shell and the cover. Due to the special shape of the square aluminum shell battery, the distance from the laser head to the solder joint is unstable and prone to bulges and air holes. Therefore, there is a high requirement for the stability of the distance from the laser head to the solder joint. Current technology suffers from the following problems: [0003] (1) Manually place the battery cells into the fixture, which is inefficient and wastes manpower; [0004] (2) When welding the square cell, it can only be welded on one side, and it needs to be turned over by hand to complete the welding of the entire circular weld, which is inefficient; [0005] ...

AI Technical Summary

Problems solved by technology

[0003] (1) Manually place the battery cells into the fixture, which is inefficient and wastes manpower;

[0004] (2) When welding the square cell, it can only be welded on one side, and it needs to be turned over by hand to complete the welding of the entire circular weld, which is inefficient;

[0005] (3) The distance from the laser head to the welding spot at the rounded corner of the circular weld seam of the square cell cannot be guaranteed to be constant, and poor welding is likely to occur
