AI Technical Summary
Existing aluminum-cased lithium battery helium-filling equipment is expensive, has a low helium-filling pass rate, and fails to achieve equal pressure inside and outside the battery during vacuuming, posing a risk of electrolyte leakage, making it difficult to meet the needs of small-batch production.
A device was designed that includes a main frame, a helium return and nailing mechanism, an automatic nailing mechanism, and an aluminum-cased battery isobaric cavity module. The device achieves automated sealed helium filling through ball screw linear module and cylinder drive, ensuring isobaric filling inside and outside the battery. The isobaric cavity module and vacuum pumping liquid return cavity are used to prevent electrolyte leakage.
It reduces equipment costs, improves helium filling pass rate, ensures battery sealing and operational safety, reduces environmental pollution and personal injury risks, and is suitable for small-batch aluminum-cased battery production.
