Semi Automatic Stacking Machine Laboratory Stacking Machine for Lithium Pouch Cell Assembly

Product Overview

This semi-automatic laboratory stacking machine is an advanced precision assembly system engineered specifically for the Z-fold stacking of lithium-ion pouch cells. By combining manual electrode loading with fully automated secondary positioning, robotic vacuum pickup, continuous separator feeding, and precision layer stacking, this equipment delivers an optimal balance of operational flexibility and high-precision automation. It is engineered to eliminate internal misalignment and separator wrinkling, establishing a dependable foundation for energy-dense cell prototyping.

Designed primarily for battery research institutes, pilot-scale testing lines, and cell manufacturing R&D centers, the system accommodates an expansive range of cell dimensions without requiring complex structural changeovers. Its single-cantilever architecture facilitates seamless access for separator roll loading, maintenance, and visual inspection. The integrated pulse-motor lateral micro-adjustment and closed-loop motion architecture empower process engineers to achieve consistent, repeatable layer alignment across diverse experimental chemistries, including solid-state, NMC, LFP, and sodium-ion pouch cell configurations.

Constructed with high-grade industrial tooling, precision linear motion guides, and an integrated PLC control core, this stacking apparatus guarantees reliable continuous operation under stringent cleanroom and dry room environments. It provides research teams and pre-production engineers with the mechanical repeatability needed to evaluate novel cathode/anode pairings, high-nickel formulations, and ultra-thin polymeric or ceramic-coated separators with total confidence in physical cell integrity.

Key Features

• Automated Servo Constant-Tension Separator Feeding: The single-cantilever roll feed incorporates a dedicated servo-driven closed-loop tension system that dynamically maintains uniform separator tautness throughout the stacking cycle, preventing material elongation, folds, and surface stress.
• Precision Photoelectric Web Edge Guide Control: High-resolution optical sensors monitor separator tracking in real time, automatically compensating for lateral roll deviations to ensure flawless separator placement and prevent internal short circuits.
• High-Accuracy Robotic Vacuum Layering: Electrodes placed in the alignment nest are securely transferred by a high-response pneumatic vacuum manipulator, ensuring sub-millimeter positional repeatability with an overall stack alignment neatness within ±0.3 mm.
• Broad Dimensional Flexibility and Modular Tooling: The platform supports electrode sizes ranging from 35 mm × 35 mm up to 200 mm × 200 mm (including tabs) through easily adjustable alignment fixtures, accommodating diverse cell form factors without dedicated retooling costs.
• Programmable Layer Count and Thickness Management: Capable of stacking up to 500 layers and a maximum pack thickness of 30 mm, the system allows operators to define exact stacking sequences and batch counts via the intuitive digital interface.
• Pulse-Motor Lateral Micro-Adjustment: Precision pulse-motor drives govern left-and-right linear traversal, providing smooth, high-precision positioning and intuitive micro-step calibration during recipe setup and process optimization.
• Industrial Touchscreen Interface and PLC Architecture: A centralized programmable logic controller paired with a responsive Human-Machine Interface (HMI) streamlines parameter configuration, operational diagnostics, and production monitoring for clean, hassle-free operation.
• Robust Single-Cantilever Pneumatic Expansion Shaft: The 3-inch pneumatic core shaft allows rapid, secure roll mounting and separator reel exchanges up to 250 mm outer diameter, maximizing uptime in active research workflows.
