ADP-300B Auto Stacking Machine

High-Precision Automatic Stacking for Pouch Cell Research and Pilot Production

The Auto Pouch Cell Electrode Stacking Machine is designed for the Z-type stacking process used in lithium-ion and sodium-ion pouch cell manufacturing. In this process, pre-cut cathode and anode sheets are alternately placed while the separator is continuously unwound and folded in a Z-pattern. This architecture is widely used in pouch cell assembly because it enables controlled layer build-up and accurate separator placement, both of which are critical to cell consistency and downstream sealing quality.

Working Principle and Key Features

The system uses a manipulator and suction-cup pick-and-place mechanism to transfer cathode and anode electrodes from their material boxes onto the stacking table after secondary positioning. The separator passes through automatic tensioning and correction modules before entering the stacking zone. Four press-blade mechanisms compress the stack, after which the formed cell is clamped, the separator is cut, and the assembly is transferred for automatic taping while the next cycle begins. Verified specifications for the TOB-ADP-300B platform include 1.3–1.5 s/pcs stacking speed, ±0.3 mm electrode/separator alignment accuracy, ±0.2 mm adjacent electrode accuracy, 98% utilisation rate, AC220V 50 Hz, 3 kW power, 0.5–0.7 MPa compressed air, 200 L/min air demand, and approximate dimensions of 2400 × 1800 × 2200 mm with a machine weight of about 2000 kg.
