Abstract

The invention discloses a liquid injection implementing method of a full-automatic lithium battery liquid injection machine. The method comprises a software system and a hardware system. By mutual cooperation of the software system and the hardware system, liquid is accurately injected into a lithium battery. The full-automatic lithium battery liquid injection machine organically combines the functions by using the software system and the hardware system to form a complete and interoperable intelligent system. The system not only has the functions, but also has functions of automatic analysis,automatic fine adjustment of a liquid injection amount and the like, and can automatically count liquid injection amount data, automatically compare the liquid injection amount data with a standard liquid injection amount and automatically calculate a liquid injection fine adjustment amount, so that the next liquid injection is more precise, and a real intelligent closed-loop control system is formed.

Description

technical field [0001] The invention relates to a lithium battery liquid injection technology, in particular to a liquid injection method for a lithium battery automatic liquid injection machine. Background technique [0002] Some of the existing liquid injection systems simply inject liquid for the battery, some systems add automatic weighing, and some add NG automatic sorting on this basis. The existing liquid injection method for lithium batteries is vacuum injection. The liquid outlet nozzle of the liquid receiving cup is docked with the liquid inlet port of the battery, and a sealing ring is used to compress the seal with high pressure, and then vacuumize them one by one. After the vacuum is completed, the electrolyte is injected, and the electrolyte will slowly penetrate into the gap between the battery electrode windings, and then compressed nitrogen gas is injected to fully infiltrate the electrolyte. [0003] Lithium battery vacuum injection has the following disad...
