2: Introduction:

The cell sealing machine is a key piece of equipment used in the lithium battery manufacturing process to seal the battery cells. It primarily performs heat sealing or cold press sealing on the battery’s sealing area, ensuring the airtightness and mechanical strength of the seal. This prevents electrolyte leakage and enhances the overall safety and performance of the battery. The machine is suitable for a variety of lithium-ion batteries, including pouch and prismatic cells.

3: Process Flow:

1. Cell Feeding: The cells are automatically fed into the sealing station through an automated feeding system.

2. Seal Positioning: The machine accurately positions the sealing area of the cell to ensure precise sealing.

3. Sealing Operation: The cell is sealed using heat sealing or cold press technology.

4. Sealing Quality Inspection: The system automatically inspects the quality of the seal to ensure it is leak-proof.

5. Product Output: The sealed battery cells are automatically discharged for the next production step.
