Problems solved by technology

In the existing electrolyte injection device, the liquid injection cup is usually replenished through a hose. After the liquid replenishment is completed, the liquid injection cup is moved to connect the liquid injection cup to the battery, and the electrolyte in the liquid injection cup is injected into the battery. , during the movement of the liquid injection cup, there will be electrolyte droplets remaining on the hose, which will lead to the inability to quantitatively inject the subsequent liquid, which will affect the accuracy of the subsequent electrolyte injection, and then affect the quality of the battery

Abstract

The invention discloses a liquid injection device and a liquid injection production line, the liquid injection device comprises a feeding part and a liquid injection part, the liquid injection part comprises a fixing plate and a liquid injection cup, the liquid injection cup is arranged on the fixing plate, the feeding part moves relative to the liquid injection part, and the feeding part conveys a battery to the position below the liquid injection cup and enables the battery to be communicated with the liquid injection cup; the electrolyte in the electrolyte injection cup is injected into the battery, and the electrolyte injection cup is kept fixed before and after electrolyte injection, so that the electrolyte injection quality can be improved, and the electrolyte injection precision is ensured; the liquid injection cup is provided with a liquid injection opening and a liquid injection pipeline, the liquid injection opening and the liquid injection pipeline are used for guiding the electrolyte, and the liquid injection pipeline can guide the electrolyte into the liquid injection cup. The liquid injection pipeline is provided with the liquid outlet, the liquid outlet is obliquely arranged, the electrolyte flows to the inner wall of the liquid injection cup from the liquid outlet, the electrolyte flows downwards along the inner wall of the liquid injection cup, the electrolyte can be prevented from directly falling to generate bubbles, and the liquid injection precision of the electrolyte is guaranteed.

Description

technical field [0001] The invention relates to the field of battery production, in particular to a liquid injection device and a liquid injection production line. Background technique [0002] Electrolyte is the carrier of ion transmission in the battery. During the production process of lithium battery, electrolyte needs to be injected through the liquid injection hole opened on it. The quality of electrolyte and the amount of liquid injection directly determine the quality of lithium battery. In the existing electrolyte injection device, the liquid injection cup is usually replenished through a hose. After the liquid replenishment is completed, the liquid injection cup is moved to connect the liquid injection cup to the battery, and the electrolyte in the liquid injection cup is injected into the battery. , During the movement of the liquid injection cup, there will be electrolyte droplets remaining on the hose, resulting in the inability to quantitatively inject the subs...
