Residual liquid collection device and liquid supplement mechanism thereof

Abstract

The present invention discloses a residual liquid collection device and a liquid supplement mechanism thereof. The residual liquid collection device comprises a residual liquid collection supporting plate, a horizontal guide component, a horizontal driving part and a residual liquid collection box body. The horizontal guide component is arranged on the residual liquid collection supporting plate,and the residual liquid collection box body is arranged on the horizontal guide component, wherein the residual liquid collection box body can perform reciprocating sliding along the horizontal direction. The horizontal driving part can drive the residual liquid collection box body to perform reciprocating sliding along the horizontal driving part. The residual liquid collection box body is provided with a residual liquid inlet, the residual liquid inlet is provided with a sealing ring, and the sealing ring is fixed at the residual liquid inlet via a fixing block. According to the residual liquid collection device, by providing the residual liquid collection supporting plate, the horizontal guide component, the horizontal driving part and the residual liquid collection box body and performing optimal design on the structures of each component, the timely cleaning of residual liquid in places where a electrolyte passes through, such as liquid injection cups, liquid injection mouths andhoses, can be realized, and thus liquid supplement precision is improved.

Description

technical field [0001] The invention relates to the field of automatic production of battery machinery, in particular to a device for collecting residual liquid and a liquid replenishing mechanism thereof. Background technique [0002] After the battery is filled with liquid, part of the electrolyte is lost due to reasons such as vacuuming and the adhesion of the liquid injection cup. Therefore, a large number of batteries often need to be replenished during the liquid injection process. At present, most lithium battery rehydration is carried out at room temperature. If there is air in the battery cell or in the rehydration pipeline, the rehydration effect will be poor, and the battery cell cannot be filled with electrolyte. [0003] In addition, after the secondary rehydration of the battery, there will be residual liquid in the place where the liquid injection cup, liquid injection nozzle, hose, etc. pass through the electrolyte. Accuracy of rehydration. [0004] Therefo...
