1. Applicable For top, bottom and side heat sealing of pouch-type liquid lithium-ion batteries, as well as short circuit testing (Three testing modes: positive & negative tab test, positive tab vs. pierced aluminum laminate, negative tab vs. pierced aluminum laminate)
2. Process Flow:
The battery with dual tab outlets is positioned within the upper and lower cavity jigs formed by aluminum laminated film. The operator places the jig into the moving mechanism. A servo motor drives the lead screw to precisely move the jig to the top/bottom sealing station, where the jig descends to perform top and bottom edge sealing.
After sealing, the jig ascends and is moved to the side sealing station, where it descends again to complete side sealing. Then the jig is transferred to the short circuit testing station, where the testing mechanism completes the circuit check.
Finally, the jig is returned to the loading station via servo drive. The operator removes and loads the jig for the next cycle.
