Problems solved by technology

[0002] The cells in the existing pouch battery are welded together to form a whole. When one cell in the pouch battery cannot be used normally, a problem arises, that is, the entire cell mold The battery pack cannot be used normally, and the defective battery cell cannot be taken out separately for replacement, only the whole battery cell module can be replaced. It is necessary to improve the existing battery cell structure so that the connection between the battery cell and the battery cell To realize the detachable function, the detachable connection between the battery and the battery needs to punch the tab of the battery, and the punching position of the tab needs to be quite accurate, which cannot be realized by the existing punching machine. Therefore, It is necessary to design a punching machine that can realize the punching of battery tabs

Abstract

The invention discloses a tab punching machine which comprises a rack, wherein an air cylinder feed mechanism and an air cylinder connecting rod punching mechanism are arranged on the rack and move left and right; a screw rod of the air cylinder feed mechanism is controlled by a servo motor to move front and back; the air cylinder connecting rod punching mechanism comprises an upper die connecting rod device, a lower die connecting rod device and a jacking air cylinder; the upper die connecting rod device and the lower die connecting rod device are controlled by the jacking air cylinder; and when the air cylinder connecting rod punching mechanism carries out punching action on a battery cell tab, the upper die connecting rod device controls an upper die to move downwards, and the lower die connecting rod device controls a lower die to move upwards. With adoption of the tab punching machine, four slotted holes are simultaneously punched in the battery cell tab, and two of the slotted holes of the battery cell tab are locked in a tab connecting piece through four screws to overlap battery cells, so that the effect of separately dismantling and replacing the battery cells is realized, and maintenance and reuse are facilitated.

Description

technical field [0001] The invention relates to a battery tab punching device, in particular to a tab punching machine. Background technique [0002] The cells in the existing pouch battery are welded together to make it a whole. When a cell in the pouch battery cannot be used normally, a problem arises, that is, the entire cell mold The battery group cannot be used normally, and the defective battery cell cannot be taken out for replacement alone, only the whole battery cell module can be replaced. It is necessary to improve the existing battery cell structure so that the connection between the battery cell and the battery cell To realize the detachable function, and the detachable connection between the battery and the battery needs to punch the tab of the battery, and the punching position of the tab needs to be quite accurate, which cannot be realized by the existing punching machine. Therefore, It is necessary to design a punching machine that can punch the tabs of the...
