Description

Technical Field

[0002] During the battery manufacturing process, in the lithium battery production filling process, when the equipment filling nozzle is separated from the battery cell filling port, electrolyte leakage often occurs and remains on the surface of the battery cell filling jig, leading to the following problems: residual electrolyte remains on the surface of the battery cell with the filling jig, causing quality problems; or gradually spreads to other equipment, causing corrosion and reducing the service life of the equipment; residual electrolyte will crystallize over time and is difficult to clean. After crystallization, the jig will cause inaccurate positioning and leakage will become more serious.

[0003] At present, most companies use manual water washing on site, which is not only inconvenient to operate, but also not clean enough. In addition, there is no feedback on the cleaning results, and the cleaning cannot form a feedback closed loop, making it impossible to determine whether the injection fixture is cleaned.
