Description

Technical Field

[0001] The utility model belongs to the technical field of battery core processing equipment, and specifically relates to a nail pulling device and a battery core processing system. Background Art

[0002] At present, in the design and manufacture of square aluminum shell batteries for energy storage, the top cover is designed with a liquid injection port and an explosion-proof valve structure. The liquid injection port is generally a through hole in the shape of a circular hole, which is used to inject electrolyte into the battery cell. Because the layout space of the top cover is limited, the liquid injection port is mostly designed to be small in size. The function of the explosion-proof valve is to reduce the risk of explosion of the energy storage battery cell. When an abnormal situation occurs in the energy storage battery cell and the internal air pressure increases, the explosion-proof valve on the top cover will be affected by the air pressure and open, thereby completing the pressure relief. Due to the small actual diameter of the liquid injection port, the matching accuracy and tolerance capability of the plastic nails used in the energy storage battery cell are relatively high. Once the positioning and matching of the plastic nails and the liquid injection port are not completely matched, it will cause electrolyte leakage, which will cause the aluminum nails to be corroded, and then cause the explosion-proof valve on the cover plate, the positive and negative poles to be contaminated by the electrolyte, and even the shell will be corroded, and there is a risk of failure or even explosion of the energy storage battery cell.

[0003] At present, the rework of the glue nails of energy storage cells is generally done by directly poking the glue nails into the battery cell, or manually pulling them out. However, after the glue nails are poked into the battery cell, due to the different group margin designs inside the battery cell, if the group margin is too large and the internal space of the battery cell is small, it will affect the internal electrode group structure of the battery cell. Manual nail pulling has the risk of deformation of the operating action due to human factors due to the different levels of operators.

[0004] Therefore, it is urgent to develop a new nail pulling device and battery core processing system to solve the above problems. Utility Model Content
