Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion battery manufacturing, and more specifically, it relates to an automatic cup-installing device for lithium ion battery manufacturing. Background Art

[0002] Liquid injection is a very important process in the production of lithium-ion batteries. The quality of the liquid injection process is directly related to the decisive indicators such as the capacity, life, and safety of the battery. Since the automatic liquid injection machine is expensive, and even if the automatic liquid injection machine is used, it still requires certain manual operation and monitoring. At present, many lithium-ion battery manufacturers still use manual liquid injection. According to the requirements of the liquid injection process, before liquid injection, it is necessary to put the liquid injection sleeve cup into the battery cell shell (usually a steel shell) after the rolling groove, and inject the electrolyte into the sleeve cup first, and then make the electrolyte penetrate into the battery cell by vacuuming and filling with nitrogen. Among them, no leakage can be allowed during the vacuuming and nitrogen filling process, and the liquid injection amount needs to be guaranteed. Therefore, the battery cell steel shell and the sleeve cup must be tightly combined, but the existing automatic sleeve cup installation device for lithium-ion battery manufacturing is inconvenient to limit the shells and sleeve cups of different sizes, and the applicability is poor.
