Abstract

The invention discloses a liquid injecting and standing device for cylindrical lithium-ion batteries. The liquid injecting and standing device for the cylindrical lithium-ion batteries comprises a battery feed mechanism, a battery hole-alignment detection mechanism, a battery fixture carrying mechanism, a battery front turnover mechanism, a battery air-tightness detection mechanism, a battery liquid injection mechanism, a battery tray rear turnover mechanism, a battery high pressure and vacuum standing mechanism, a battery blanking mechanism and a battery tray carrying mechanism. The liquid injecting and standing device for the cylindrical lithium-ion batteries adopts the battery feed mechanism and the battery blanking mechanism to respectively realize the automatic feeding and blanking ofa mechanical arm, adopts the battery front turnover mechanism to realize the feeding and blanking of a liquid injection cup, adopts the battery high pressure and vacuum standing mechanism to performhigh pressure and vacuum operations alternately so as to fully prolong the standing time after liquid injection of the batteries, and adopts the battery tray carrying mechanism to realize the turnoverof a battery tray among the different mechanism. The liquid injecting and standing device realizes mechanized automatic feeding, hole-alignment, liquid injection, standing and blanking operations, isstable in standing time and high in efficiency, and guarantees the accuracy and time stability of liquid injection and standing.

Description

technical field [0001] The invention relates to the field of processing and manufacturing of cylindrical lithium ion batteries, in particular to a liquid injection and static device for cylindrical lithium ion batteries. Background technique [0002] At present, with the continuous development of the battery industry, the competition among domestic lithium battery manufacturers is becoming more and more fierce, and the requirements for lithium-ion batteries in the market are getting higher and higher. As the process of lithium-ion batteries continues to become more complex, the requirements for the manufacturing process of its batteries are becoming more and more stringent. In order to improve the cost performance of the manufacturing equipment, the functional requirements that the equipment needs to meet also increase. When injecting liquid into traditional batteries, cylindrical lithium-ion batteries need to be pressurized or evacuated multiple times after liquid injection...
