Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, and in particular to a lithium battery top-side sealing machine. Background Technology

[0002] Lithium-ion batteries are rechargeable batteries that primarily function by the movement of lithium ions between the positive and negative electrodes. A lithium-ion battery cell consists of a positive electrode, a separator, and a negative electrode. Top sealing and side sealing involve encapsulating the top and sides of the battery with an aluminum-plastic film. Current sealing mechanisms typically only perform one function: either top sealing or side sealing. Furthermore, the sealing process often requires manual loading and securing of the battery to the heat-sealing position. The heat-sealing blade reaches temperatures as high as 180-200°C, posing a risk of burns. Manual control of the sealing position is also difficult, leading to poor sealing. Additionally, existing top-sealing and side-sealing machines lack versatility and have limited compatibility with different models, resulting in high development and production costs.
