Automatic Linear 4-in-1 Top & Side Hot Sealing Machine Heat Sealer for Pouch Cell

I. Functional Overview

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:

A battery featuring dual tab outlets is situated in the upper and lower cavity jigs made of aluminum laminated film. The operator inserts the jig into the moving mechanism. A servo motor drives the lead screw to accurately transport the jig to the top/bottom sealing station, where the jig lowers to carry out top and bottom edge sealing.

Once sealed, the jig rises and is moved to the side sealing station, where it lowers again to finish side sealing. The jig is then transferred to the short circuit testing station, and the testing mechanism conducts the circuit check there.

In the end, the jig is sent back to the loading station through servo drive. The operator takes out the jig, loads a new one, and the next cycle begins.
