Double-flanging equipment and battery cell manufacturing system

Abstract

The invention provides double-flanging equipment and a battery cell manufacturing system. The double-flanging equipment is used for being integrated with edge cutting equipment, and the double-flanging equipment comprises a first sharing plate, a second sharing plate, a first adjusting seat, a second adjusting seat, a first edge folding mechanism and a second edge folding mechanism, wherein the first sharing plate is used for being arranged on one side of a connecting guide rail of a base and used for installing a first edge cutting mechanism of the edge cutting equipment; the second sharing plate and the first sharing plate are oppositely arranged, and the second sharing plate is used for being arranged on the other side of the connecting guide rail and used for installing a second edge cutting mechanism of the edge cutting equipment; the first adjusting seat is arranged on the first sharing plate; the second adjusting base is arranged on the second sharing plate, and the second adjusting base and the first adjusting base are oppositely arranged. Before edge cutting treatment, a battery cell is accurately positioned on a clamping and positioning mechanism, the clamping and positioning mechanism slides to the positions corresponding to the edge cutting equipment and the double-flanging equipment through the connecting guide rails respectively, and respective positioning adjustment is not needed, so the manufacturing precision and efficiency of the battery cell are improved.

Description

technical field [0001] The invention relates to the technical field of battery cell manufacturing, in particular to a double-folding device and a battery core manufacturing system. Background technique [0002] The cell processing process includes initial positioning, vacuum packaging, material cutting, edge ironing, positioning, edge trimming, bending and edge ironing. Since the cells contain toxic and harmful substances, the lithium battery needs to be packaged after the liquid injection process is completed. The generated gas is extracted, and then the aluminum-plastic film is heated and pressurized in a vacuum environment to realize the vacuum packaging of the battery cell, so as to prevent the lithium battery from leaking when it is sold on the market. The traditional cell manufacturing system uses multiple single-folding equipment to fold the sides of the cell in sequence, and the cell needs to be transported and repositioned multiple times in the middle, so that the ...

AI Technical Summary

Problems solved by technology

The traditional battery manufacturing system uses multiple single-folding equipment to fold the sides of the battery in sequence, and the battery needs to be transported and repositioned several times in the middle, so that the edges of the battery after cutting off the edges The folding accuracy is low, which affects the subsequent heat sealing accuracy of the battery cell

In addition, since the edge folding equipment and edge trimming equipment of the traditional cell manufacturing system are separate devices, the cells need to be positioned precisely at the corresponding stations, making the manufacturing accuracy and efficiency of the cells low.
