Lithium battery cap linear laser welding device and welding method thereof

Abstract

The invention belongs to the technical field of lithium battery cap welding equipment, and particularly relates to a lithium battery cap linear laser welding device. The device comprises a rack, wherein the rack comprises a workbench; four supporting legs are fixedly mounted at the bottom of the workbench; supporting plates are fixedly mounted on the inner sides of the four supporting legs; two vertical blocks are fixedly mounted at the top of the workbench; fixing blocks are fixedly mounted at the tops of the two vertical blocks; and top plates are fixedly mounted at the bottoms of the two fixing blocks. Through cooperation of an orifice plate feeding mechanism, an explosion-proof diaphragm feeding mechanism and two displacement mechanisms, automatic mechanized feeding of orifice plates and explosion-proof diaphragms can be achieved, manual feeding operation is not needed, the feeding efficiency is improved, the labor cost is reduced, and the machining efficiency is improved. By meansof a rotary plate mode, compared with adoption of a conveying belt, the overall occupied area of the device is small, and installation and placement are convenient.

Description

technical field [0001] The invention relates to the technical field of lithium battery cap welding equipment, in particular to a linear laser welding device for a lithium battery cap and a welding method thereof. Background technique [0002] Lithium batteries have the characteristics of high specific energy, low self-discharge rate, good high and low temperature performance, long charge and discharge life, and no memory effect. At present, it is widely used in mobile phones, notebook computers, digital cameras, electric vehicles, electric tools and new energy vehicles and other products. [0003] The lithium battery cap is a component of the lithium battery, which acts as a positive conductive terminal on the lithium battery, acts as a safety valve, and also provides a battery sealing function. The lithium battery cap includes explosion-proof diaphragm, rubber ring, explosion-proof diaphragm, aluminum / nickel sheet and orifice plate. The explosion-proof diaphragm is install...

AI Technical Summary

Problems solved by technology

[0004] Mainly manually put the orifice plate and the explosion-proof diaphragm into the placement seat on the conveyor belt in order. The transmission belt is a circular circular transmission belt, and then the placement seat moves to the bottom of the laser welding head with the rotation of the conveyor belt, and then after the welding work is completed, Relying on manual removal of the finished cap after welding, the entire welding device has many manual operations, and many people are required to cooperate in the production process, resulting in low production efficiency and high labor costs.
