Abstract

The invention discloses a liquid injection device which comprises a liquid injection head, a lower cavity, an upper cavity, a valve guide rod, a liquid feeding sealing rod, a high-pressure cavity anda battery clamp, wherein the high-pressure cavity is sealed with the battery clamp; the liquid injection head is mounted on the high-pressure cavity and is in elastic sealing communication with a battery liquid injection hole in a liquid injected battery; the lower cavity is communicated with a vacuum pipeline and is in sealing communication with the liquid injection head; electrolyte is stored inthe upper cavity. The liquid injection device has the advantages of being simple in structure, convenient to operate, low in implementation cost, high in liquid injection efficiency, good in batteryliquid injection quality, small in environment pollution, and the like that the prior art does not have.

Description

technical field [0001] The invention relates to a partial component in the field of battery processing, in particular to a liquid injection device. Background technique [0002] With the continuous development of the new energy industry, there are more and more applications of batteries. In the battery production process, injecting electrolyte into the battery is an important process in the battery production process. The device that injects the electrolyte into the battery is called a liquid injection device. [0003] Due to the limitation of design or structure of the traditional liquid injection device, the liquid injection process often needs to vacuumize the battery and then inject the electrolyte into the liquid injection cavity. This structure has low production efficiency and greatly increases the internal capacity of the battery. In addition, the traditional liquid injection needle is often an exposed mobile liquid injection structure. During the movement of the liq...
