Embodiment Construction

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] A lithium battery cell, the welding process comprises the following steps in sequence:

[0023] (1) Loading, put multiple battery cells into the cell fixture;

[0024] (2) Feeding, the cell fixture moves on the feeding belt until the position of the cell fixture is at the discharge end of the feeding belt, and the claw on the feeding device rotates clockwise until the front of the claw contacts the electric At the rear of the core fixture, the claw pushes the battery core fixture forward and enters the clamping device;

[0025] (3) Clamping, the lower clamping mechanism clamps the cell fixture in the axial direction of the clamping slide rail through the push block and the blocking block; the upper clamping mechanism presses the cell fixture on the clamping slide through the lower pressure plate. On the rail, clamp the cell fixture in the vertica...

Abstract

The invention relates to the technical field of lithium batteries and provides a battery cell of the lithium battery. A welding technology sequentially comprises the following steps: charging, feeding, clamping, welding and discharging. The battery cell of the lithium battery has the advantages that full-automatic operation of a whole welding process of the battery cell of the lithium battery is realized, and the welding quality and welding efficiency of the battery cell are high.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to the cells of lithium batteries. Background technique [0002] The welding of lithium battery cells is an important process link in the production of lithium batteries. The main process is to weld metal sheets on the cells of lithium batteries. At present, the welding of lithium battery cells has been widely used in automatic welding machines. The existing problems in the welding of lithium battery cells are: 1. The auxiliary positioning accuracy of lithium battery welding is not high, resulting in low welding quality; 2. Although the welding of lithium batteries has been automated, the loading and unloading is still manual. , the degree of automation is low, resulting in low processing efficiency. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned deficiencies in the welding of existing lithium battery cells, the purpose of the present invention...
