Package Mylar
Wrap Mylar film around the bare core and the bottom of the bare core. Mylar film is mainly used to prevent the core from contacting with the shell and prevent the occurrence of short circuit.
Requirements
1. The incoming material of the battery core is smooth and aligned;
2. Mylar film smooth, no static electricity;
3. Hot melt temperature to meet the requirements, welding area to meet the requirements, Mylar film and maintain the support bonding;
4. Stick glue after the envelope to ensure that the film will not be stretched and the tape will not fall off.
Specific process
Battery Cell Loading: Placing the battery cell on the production line.
Top Cover Scanning: Scanning the top cover of the cell to confirm its information.
NG Buffer: If the result of scanning code is NG (not qualified), the cell will be cached.
Battery Cell Positioning: Positioning the battery cell in the correct position.
Mylar Film Loading: Place the base film and Mylar film on the production line.
Bottom Support and Mylar Hot Melt
Mylar Film Clamping: The Mylar film is fixed in the clamp.
Battery Cell Clamping: The battery cell is fixed in the clamping device.
Battery cell holder and Mylar film top cover hot melt
Battery cell holder and Mylar film side cover hot melt
Glue on the bottom
The core out fixture
CCD Inspection: The CCD camera is used to visually inspect the battery cell.
NG Buffer: If the CCD detection result is NG, the cell is also cached.
Battery Cell Unloading: the removal of a battery cell from a production line.
The whole flow chart shows the complete process from the battery charging to the inspection, including the steps of scanning code, positioning, fixture fixing, hot melt processing and visual inspection, as well as the cache processing when the inspection is not qualified.
