Abstract

A liquid injection apparatus for battery vacuum is disclose, comprises a frame and an upper transition cup mechanism installed on the frame, a vacuum chamber, a lower transition cup mechanism and a lifting mechanism, wherein the upper transition cup mechanism comprises an upper transition cup, the lower transition cup mechanism comprises a lower transition cup and a battery carrier plate, and thelifting mechanism is used for lifting the lower transition cup mechanism into the vacuum chamber. The vacuum injection device of the battery has the advantages that the battery absorbs the electrolytequickly, the battery injection efficiency is high, the battery productivity is high, and the injection precision is good, which are not possessed by the prior art.

Description

technical field [0001] The invention relates to the field of lithium battery production, in particular to a battery vacuum liquid injection device. Background technique [0002] With the maturity of new energy technology and its large-scale promotion and application, the requirements for lithium battery production equipment in the market are also getting higher and higher. [0003] In the production process of lithium batteries, injecting electrolyte into lithium batteries is a very important process in the production of lithium batteries. [0004] In the existing lithium battery production equipment, the battery is generally vacuumized or pressurized after the battery is injected. This injection process causes the battery to absorb the electrolyte at a slower rate, which in turn leads to a lower battery injection efficiency. Low, it is difficult to meet the current market demand, and it also leads to high production costs. The existing liquid injection equipment has defect...
