Automatic Top and Side Heat Sealing Machine for Pouch Cell Production Line

1. Equipment Description

This equipment is mainly applied to automatic top sealing (left and right), side heat sealing, edge trimming, flaring, and testing of pouch cell lithium-ion batteries, and is compatible with certain prismatic cells. It adopts a rotary dual-station operation mode.
The workflow is: loading → left top sealing → right top sealing → side sealing → edge trimming → testing → flaring → unloading.

6. Functional Description

- 6.1 Soft sealing process is applied to both top and bottom sealing.
- 6.2 Cell fixtures come with locating holes, which align with positioning pins on the rotary table to secure sealing precision.
- 6.3 Sealing time for top, bottom, and side sealing is adjustable via the touchscreen.
- 6.4 Pneumatic cylinders are used for all sealing operations; sealing pressure is modified through pressure regulating valves on the control panel.
- 6.5 Temperature is managed by temperature control modules or controllers.
- 6.6 The positioning fixture works on a one-out-one basis — one cell is placed each cycle.
- 6.7 SKD11 cutting blades are adopted at the edge trimming station, with a single sharpening life surpassing 300,000 cycles and over 10 resharpening opportunities.
- 6.8 Pneumatic cylinders with probes are utilized at the testing station for inspection.
- 6.9 The flaring station employs a vacuum suction cup in collaboration with flaring tools.
