AI Technical Summary
Technical Problem
It is difficult to close the stop valve in time when the existing liquid injection system leaks, resulting in large amounts of electrolyte leakage and easy spread, posing a safety hazard.
Method used
A combination of a controller, an infusion component, an isolation component, an injection piece and a detection component is used. The detection component detects leakage, and the controller controls the first valve to close and the isolation component to isolate the leaking component, thereby achieving rapid response and reducing the spread of leakage.
Benefits of technology
Timely detection and rapid response to leaks can reduce electrolyte leakage, improve safety, reduce the spread of leakage, and reduce safety hazards.

Abstract
The invention relates to the technical field of battery production, in particular to a liquid injection system. The liquid injection system comprises a controller, at least two liquid conveying assemblies, at least one isolation assembly, at least two liquid injection pieces and at least two detection assemblies, all the liquid conveying assemblies are sequentially arranged, and first valves are arranged at the ends of the liquid conveying assemblies. The isolation assembly is correspondingly arranged between the two adjacent infusion assemblies; the liquid injection part is correspondingly arranged on one side of the liquid conveying assembly. The detection assemblies are correspondingly arranged on the infusion assemblies and used for detecting whether leakage happens to the corresponding infusion assemblies or not. When the infusion assemblies leak, the controller controls the corresponding first valves to be closed and controls the adjacent isolation assemblies to isolate the leaked infusion assemblies. According to the liquid injection system provided by the invention, the leakage problem can be found in time, a response can be quickly made, the leakage amount of the electrolyte is reduced, the leaked liquid conveying assembly is isolated, the diffusion of the leaked liquid is reduced, and the safety is improved.
