This dual-station stacking machine is mainly used for the "Z"-fold stacking process of prismatic battery cells. It stacks cathode sheets, anode sheets, and separators into a battery cell through the Z-fold stacking process, by side tape application, QR code labeling, and cell unloading into the next process. The equipment consists of the following components: material box feeding mechanism, cathode/anode alignment mechanism, electrode sheet transfer robot, separator unwinding unit, stacking table unit, separator hot-cut mechanism, cell transfer unit, adhesive tape application unit, QR code labeling unit, and cell unloading mechanism. It is used for fully automated production of pouch and prismatic cells.
(1) Electrode length refers to the direction of the tab, excluding the tab length.
(2) Electrode sheets should be free of significant powder drop and wavy edges; die-cutting error < 0.3mm.
(3) No obvious warping or adhesion between electrode sheets.
(4) Separator serpentine deviation: 1mm/1000mm.
The electrode trays are delivered to the machine via logistics line. Upon detection, the robotic arm starts automatically picking sheets from the tray.
The electrode picked from the tray is placed onto the alignment platform. CCD inspection and XYZ motion system performs secondary alignment to ensure stacking accuracy.
Driven by linear modules, the inner and outer suction arms move the electrode from tray → alignment platform → stacking table, coordinating with separator unwinding and stacking to complete Z-fold stacking.
The full roll separator is unwound continuously with tension control, buffering, and edge correction. Coordinated with the electrode sheet transfer robot and the reciprocating motion of the stacking table, Z-fold stacking is completed.
The electrode transfer robot places sheets into the stacking table. Pressing blades alternate to compress the sheets while the table switches between cathode and anode positions, completing Z-fold stacking.
Uses thermal cutting; a heating element rapidly heats to cut the separator after stacking.
Transfers finished cells from the stacking table to the separator cutting, tail winding, and taping station.
Automatically pulls, cuts, scans, and applies QR-coded tape to the cell surface. Automatically rejects defective QR codes.
Clamps the cell with upper and lower plates, by side adhesive application.
Control operation of each unit via touch screen interface.
