Lithium Ion Battery Z Type Semi Automatic Stacking Machine

Product Overview

This semi-automatic stacking machine is designed for the Z-shaped stacking process used in lithium-ion battery cells. It alternates positive and negative electrode sheets with separator material, using a cylinder-driven left-to-right separator movement to form the stack. An automatic separator tension-control system supports stable handling of the separator during operation, while the cantilevered layout keeps the working area accessible for electrode placement and stack removal.

The equipment is intended for battery R&D sample preparation and small-batch trial production. It accommodates a broad cell stacking size range, from 44 mm x 44 mm to 200 mm x 150 mm including tab length, making it suitable for evaluating different cell formats within the stated limits. It is particularly relevant to lithium-ion battery laboratories, pilot lines, university research groups, and materials-development teams preparing stacked electrode assemblies.

Compared with manual stacking, this unit is built to improve stacking efficiency and stack neatness. Alignment accuracy is specified as better than +/-0.5 mm, and the system includes automatic counting, zeroing, and a digital timer. Retention of the previous operating parameters after a power interruption or period of non-use helps maintain an established setup during repeated development work.

Key Features

• Z-Shaped Electrode and Separator Stacking: The system combines positive and negative electrode sheets with separator material in a controlled Z-shaped sequence. Cylinder-driven separator movement provides the left-to-right motion required for the stacking process.

• Automatic Separator Tension Control: A separator tension-control system manages separator handling during operation. This controlled approach supports orderly stacking and helps users maintain consistent separator presentation as layers are assembled.

• Specified Stack Alignment: Stack neatness is specified as better than +/-0.5 mm. This capability is important where electrode and separator positioning must be evaluated carefully during cell sample development and process trials.

• Broad Cell Size Coverage: The equipment handles stacked cell sizes from a minimum of L44 mm x W44 mm to a maximum of L200 mm x W150 mm, including tab length. The maximum size applies when the tabs are located on the long side, providing a clearly defined operating envelope for format selection.

• Semi-Automatic Foot-Pedal Control: A foot switch controls cylinder action. This gives the operator a direct method for actuating the stacking sequence while working at the cantilevered operating area.

• Automatic Count and Reset Functions: Automatic counting records stacking activity, while the zeroing function supports a fresh count for a new run, sample group, or process evaluation. These functions simplify routine tracking during repeated laboratory work.

• Digital Timing Display: A digital timer is included to provide visible timing information during operation. This supports repeatable workflow observation when teams are comparing stacking conditions or preparing multiple development samples.

• Parameter Retention After Interruption: The unit automatically retains the last-used parameter status after a power outage or after it has not been used. This feature supports operational continuity by preserving the previously established setting state.

• Accessible Cantilevered Construction: The cantilevered design is intended to make the equipment easier to operate. The open arrangement supports access during electrode placement, separator handling, and removal of completed stacks.

• Compact Laboratory Footprint: With overall dimensions of L512 mm x W820 mm x H580 mm and an approximate weight of 50 kg, the machine provides a compact form factor for laboratory and pilot-scale environments while supporting a substantial stated stacking-size range.

Why Choose This Product

• Purpose-built for battery stacking: The equipment is specifically configured to stack positive and negative electrode sheets with separator material in a Z-shaped cell-assembly process, rather than relying on a fully manual method.

• Controlled, repeatable operation: Automatic separator tension control, cylinder-driven separator movement, foot-pedal actuation, counting, zeroing, and digital timing provide practical functions for repeated laboratory and small-batch work.

• Defined precision and format capability: Specified stack neatness better than +/-0.5 mm and the stated cell-size range give procurement and engineering teams clear criteria for matching the unit to planned sample formats.

• Practical long-term usability: Simple adjustment, operation, and maintenance, together with retention of the previous parameter state after interruption or non-use, support continued use in changing R&D environments.

• Compact integration with configurable supply voltage: The compact equipment dimensions and available 110 VAC customization option help teams evaluate installation requirements alongside their existing laboratory utilities.
