Automatic cleaning apparatus of crystallization electrolyte of lithium battery electrolyte injection station

Abstract

The invention discloses an automatic cleaning apparatus of a crystallization electrolyte of a lithium battery electrolyte injection station. The automatic cleaning apparatus comprises a bottom plate,a fixed plate, a movable plate and a water tank; the fixed plate is arranged on the bottom plate through a hosting apparatus for driving the fixed plate to lift perpendicularly; a transverse guiding rail is formed in the bottom of the fixed plate; the movable plate is glidingly mounted on the transverse guiding rail; the fixed plate is also provided with a driving apparatus for driving the movableplate to slide along the transverse guiding rail in a reciprocating manner; multiple brush bodies for cleaning the peripheral surface of an electrolyte injection cavity of the lithium battery electrolyte injection station are fixedly arranged on the movable plate; multiple avoidance hole grooves for allowing the electrolyte injection cavity to pass through to be in contact with the correspondingbrush bodies are formed in the fixed plate; a water inlet, a brush, multiple water outlets and hole channels for connecting the water inlet and each water outlet are arranged on each brush body; and the water inlets of the brush bodies are connected with the water tank through water pumps. The automatic cleaning apparatus has the beneficial effects of no modification on the existing equipment, compact structure, a full automatic operation and the like.

Description

technical field [0001] The invention relates to the technical field of electrolyte cleaning, in particular to an automatic cleaning device for crystallized electrolyte of a lithium battery injection station. Background technique [0002] With the improvement of the energy density of lithium batteries, and in order to obtain greater production capacity, the automatic liquid injection equipment of lithium batteries now generally adopts the positive pressure liquid method. Compared with the previous vacuum filling, the efficiency of positive pressure filling has been significantly improved. The reason is that the positive pressure provides a higher chamber pressure, usually up to 5 times that of the vacuum liquid method. However, the high cavity pressure also brings a bad side, that is, the sealing problem of the liquid injection cavity. Due to the increase of the sealing difficulty coefficient, there will inevitably be a small amount of leakage in the liquid injection mechan...

Problems solved by technology

Another aspect is the volatility of the electrolyte. Electrolyte crystallization exists on the outer peripheral surface of the liquid injection chamber after high-frequency use, which affects the sealing of the liquid injection chamber and the cleanliness of the equipment, which in turn affects the product quality to a certain extent.

[0003] The cleaning of the crystallized electrolyte on the outer peripheral surface of the liquid injection cavity has thus become a problem that needs to be dealt with. At present, it is manually cleaned temporarily, but due to the relatively compact structure, there are cleaning dead ends; Difference
