Lithium Ion Battery Semi Automatic Stacking Machine

Product Overview

This semi-automatic stacking system is engineered for Z-fold assembly of lithium-ion cell positive electrodes, negative electrodes, and separator material. Operators manually load electrode sheets, while automated positioning, robotic sheet pickup, separator pulling, correction, and layer-by-layer stacking deliver a controlled and repeatable assembly process. The result is a practical balance of operator flexibility and automated accuracy for development-scale pouch and stacked-cell work.

The equipment is suited to lithium-ion battery R&D, prototype preparation, and sample fabrication where cell formats may change frequently. Adjustable positioning fixtures accommodate a broad battery-size range, allowing laboratories to adapt the process without replacing the complete system. Its single-cantilever arrangement, automatic separator web control, and programmable stack count support organized work on varied electrode designs.

Designed for demanding laboratory operation, this unit combines PLC control, HMI operation, pulse-motor positioning, and automatic separator handling. Servo constant-tension control and photoelectric web-guiding control help maintain separator stability throughout the stacking cycle, while the specified stacking accuracy supports consistent alignment in multilayer cell assemblies.

Key Features

• Z-Fold Stacking Architecture: The equipment performs Z-shaped stacking for positive electrodes, negative electrodes, and separator material. This arrangement supports the construction of stacked lithium-ion cells with a clearly controlled layer sequence.

• Semi-Automatic Electrode Loading: Electrode sheets are manually loaded, giving researchers direct control when processing changing materials, dimensions, or prototype designs. After loading, the system automatically positions the sheets, uses a robotic arm for pickup, and completes the stacking process.

• Automatic Separator Pulling and Handling: The separator is automatically drawn through the assembly process rather than being manually placed between every electrode layer. This reduces repetitive handling steps during multilayer stack preparation and supports a more orderly operating sequence.

• Servo Constant-Tension Separator Control: Automatic servo constant-tension control manages the roll-fed separator web during operation. Stable web tension is essential to keeping separator material controlled as it is pulled and folded through the Z-stacking path.

• Photoelectric Web-Guiding Correction: Automatic photoelectric correction is applied to the separator web. This control function helps guide roll material during feeding and works with the tension-control system to maintain a stable separator path.

• Programmable Layer Count: The number of stacked layers can be preset and automatically controlled up to the stated maximum. This capability allows users to configure the equipment for different cell designs while maintaining a defined stacking target through the automated cycle.

• High-Precision Stack Alignment: Specified stacking neatness of ≤±0.3 mm provides a clear alignment benchmark for buyers evaluating prototype and sample-cell assembly quality. Automatic electrode positioning and pulse-motor-controlled left-right movement support fine positional adjustment.

• Wide Fixture-Adjustment Compatibility: Battery dimensions can be changed by adjusting the positioning fixtures, with a substantial usable range from small development cells to larger samples. This compatibility-focused design is valuable where multiple cell sizes are processed on one platform.

• PLC and HMI Operation: PLC control with an HMI interface provides a straightforward operating and maintenance approach. Users can set relevant process values, including layer quantity, through an accessible control arrangement rather than relying on purely manual sequencing.

• Service-Oriented Mechanical Design: The operating surfaces and moving components are designed for practical upkeep. Regular cleaning of the swing roller and stacking table, lubrication of bearings and slide-rail motion points, and inspection of fasteners help maintain smooth movement and dependable use.

Applications

Technical Specifications

The stated operating envelope should be reviewed alongside the intended electrode dimensions, tab arrangement, separator roll format, available electrical supply, and compressed-air installation. For best operational consistency, install the equipment in the recommended environment, free from vibration and electromagnetic interference. Maintaining the specified environmental conditions helps preserve stable mechanical movement and supports the separator-control functions during routine use.

The separator configuration is especially important during installation planning. The system is specified for a separator roll up to 250 mm in diameter, using a 3-inch roll core secured by a pneumatic expanding shaft. Confirm that the selected separator roll meets these physical requirements and that the compressed-air source remains within the specified pressure range. This preparation supports secure roll clamping and controlled separator feeding.

For sustained performance, incorporate the listed care practices into laboratory operating procedures. Keep the swing roller and stacking platform clean, lubricate bearing and slide-rail movement points, and inspect mechanical fasteners regularly. When the unit is placed in extended storage, clean the exterior surface before wrapping and storing it. These direct maintenance actions help keep the motion system orderly and reduce the risk associated with loose hardware.

Why Choose This Product

• Purpose-built for flexible cell development: The combination of manual electrode loading and automated stacking gives laboratories practical control over changing development materials while retaining an organized, repeatable assembly sequence.

• Precision-focused separator management: Servo constant-tension control and photoelectric web-guiding correction address two critical roll-fed separator handling functions within the stacking process, supporting stable material travel during automated folding.

• Broad format adaptability: Adjustable positioning fixtures cover battery sizes from L35mm W35mm to L200mmW200mm, including tabs. This provides meaningful flexibility for teams developing more than one supported cell format.

• Defined automation and usability: PLC control, HMI operation, preset layer-count control, robotic pickup, automatic positioning, and pulse-motor lateral movement create a clearly specified operating platform for research and sample fabrication.

• Built for maintainable operation: Accessible routine-care requirements—cleaning, lubrication, inspection, and proper storage—support disciplined long-term operation and help protect the consistency of the mechanical assembly process.
