Automatic Thermal Sealing for Square Pouch Lithium-ion Cell Top/Side Edges & Pouch Cylindrical Cell Top Edges

I. Functions and Working Process

l Function:

Performs thermal sealing on the top and side edges of square pouch lithium-ion cells, or top edge sealing for pouch cylindrical cells.

l Working Process:

Place the battery in the battery tray. Press the two control buttons on the front of the operation panel, and the machine will automatically rotate the turntable to move the battery to the sealing position. The upper and lower heat sealing bars will then thermally seal the battery's edge. After maintaining pressure for the set time, the heat sealing bars will retract to their initial positions. When the next battery is loaded, the previously sealed one can be taken out.

If there is no battery in the tray, the corresponding upper and lower heat sealing bars will not activate.

IV. Process Performance

1. 4-station rotary structure with two sets of heat sealing heads  

2. Independent adjustment of top and side sealing temperatures (ambient to 250°C)  

3. For square pouch cells, simultaneous top and side sealing is achievable; both soft and hard sealing processes can be realized by replacing sealing strips  

4. Touchscreen operation with PLC control  

5. Independent adjustment of top and side sealing pressures and cylinder strokes  

6. Independent adjustment of top and side sealing times (0–99.9 seconds)  

7. A safety light curtain is installed at the front of the machine; if any body part enters during operation, the machine will immediately reset automatically, ensuring safety and reliability
