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

Abstract

The invention discloses an automatic cleaning device for crystallized electrolyte of a lithium battery liquid injection station, comprising a bottom plate, a fixed plate, a moving plate and a water tank. The fixed plate is arranged on the bottom plate through a lifting device that can drive the fixed plate to vertically lift The bottom of the fixed plate is provided with a transverse guide rail, and the movable plate is slidably installed on the transverse guide rail. The fixed plate is also provided with a driving device for driving the movable plate to slide back and forth along the transverse guide rail. For the brush body that cleans the outer peripheral surface of the liquid injection chamber of the lithium battery liquid injection station, a plurality of give way holes for the liquid injection chamber to pass through to contact the brush body are arranged on the fixed plate. The body is provided with a water inlet, a brush, a plurality of water outlets and channels connecting the water inlet and each water outlet, and the water inlet of the brush body is connected to the water tank through a water pump. The beneficial effect of the invention is that it does not need to modify the existing equipment, and has the advantages of compact structure, full-automatic 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 cavity 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 mechani...
