Soft-packed cell electrode lug cutting die

Abstract

The invention discloses a soft-packed cell electrode lug cutting die. The soft-packed cell electrode lug cutting die comprises an upper die and a lower die, the upper die comprises an upper die seat,an upper fixed plate made of non-metallic materials is arranged below the upper die seat, two main punching-shearing mechanisms used for cutting the soft-packed cell electrode lug are arranged below the upper fixed plate, and the two main punching-shearing mechanisms are arranged symmetrically left and right on the center axis of the die. The lower die comprises a lower die seat, a lower fixed plate made of non-metallic materials is arranged below the lower die seat, two lower templates used for placing the soft-packed cell are fixedly arranged above the lower fixed plate, and the two lower template are arranged symmetrically left and right on the center axis of the die, and the locations of the two lower template correspond to the two main punching-shearing mechanisms separately. The soft-packed cell electrode lug cutting die can cut electrode lugs at the two ends of the soft-packed cell simultaneously at a time, it is ensured that the cell cannot have short circuit risk, high precision and great consistency of the electrode lugs after punching is ensured, and the machining efficiency is greatly improved by machining the electrode lugs of the soft-packed cell by the die.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for cutting tabs of soft-packed electric cores. Background technique [0002] At present, the tabs of soft-packed batteries used in the industry (such as lithium battery soft-packed batteries, super capacitor soft-packed batteries, lithium-ion capacitor soft-packed batteries, etc.) are cut with simple manual tools. This tool is a simple tooling device. The two lugs of a soft-packed battery need to be cut manually twice. After the two ends of the lugs are cut twice, it is difficult to ensure the consistency of the structural size. Due to the poor consistency of the size, it brings a lot of difficulties to the assembly of the battery cells in the later stage. Some cells need to be manually modified to ensure the smooth assembly. Therefore, when the cells are grouped into PCAK, the efficiency is low, and the improper operation is also reduced. pass rate. The biggest problem caused by poor consiste...

[0002] At present, the tabs of soft-packed batteries used in the industry (such as lithium battery soft-packed batteries, super capacitor soft-packed batteries, lithium-ion capacitor soft-packed batteries, etc.) are cut with simple manual tools. This tool is a simple tooling device. The two lugs of a soft-packed battery need to be cut manually twice. After the two ends of the lugs are cut twice, it is difficult to ensure the consistency of the structural size. Due to the poor consistency of size, it brings a lot of difficulties to the assembly of batteries in the later stage. Some batteries need to be manually modified to ensure the smooth assembly. Therefore, when the batteries are grouped into PCAK, the efficiency is low, and improper operation is also reduced. pass rate

The biggest problem caused by poor consistency is that the automatic production cannot be satisfied when the pouch cells are grouped into PACKs
