Abstract

The invention discloses a liquid injection device and a battery production system. The liquid injection device comprises a liquid holding device comprising a liquid holding cup and a liquid holding cup base, wherein the liquid holding cup base comprises a connection base and a first liquid injection pipe and a second liquid injection pipe which are respectively extended outwards from the two endsof the connection seat and communicate to each other, the connection base is in seal connection with the bottom portion of the liquid holding cup, allows the first liquid injection pipe to be extendedinto the liquid holding base and allows the second liquid holding pipe to be exposed externally out of the liquid holding cup, and the connection base and the liquid holding cup form a holding cavity; a pressing has a reserved channel configured to avoid the first liquid injection pipe, the diameter of the reserved channel is larger than that of the first liquid injection pipe, the pressing rod is extended into the liquid holding cup through the top portion of the liquid holding cup, the periphery wall of the pressing rod is in sealing and sliding fit with the inner periphery wall of the liquid holding cup, the pressing rod is configured to press the liquid in the holding cavity into the first liquid injection pipe through the periphery wall of the reserved channel and the outer peripherywall of the first liquid injection pipe. Through arrangement of the pressing rod and the liquid holding component, the liquid injection device can improve the liquid injection precision and can shorten the duration of the liquid injection.

Description

technical field [0001] The present application relates to the technical field of battery production equipment, in particular to a liquid injection device and a battery production system. Background technique [0002] With the development of society, various electronic devices are used more and more widely, and the demand for batteries, especially lithium-ion batteries, is increasing year by year. During the manufacturing process of the battery, electrolyte needs to be injected into the battery casing. In the prior art, there are mainly problems of low liquid injection precision and long liquid injection time in the electrolyte injection process. Contents of the invention [0003] This application mainly provides a liquid injection device and a battery production system to solve the problems of low liquid injection precision and long liquid injection time in the liquid injection process. [0004] In order to solve the above technical problems, a technical solution adopted...
