Laboratory Pneumatic Battery Electrode Sheet Die Cutting Machine

Product Overview

This laboratory pneumatic battery electrode sheet die cutting machine is a compact, pneumatically driven system for forming battery electrode sheets with controlled dimensional accuracy and clean cut quality. Sheet electrodes are placed at the cutting position, then a start valve actuates the cylinder and die-cutting assembly to form the part automatically. The finished electrode is removed directly after cutting, supporting a straightforward and repeatable preparation workflow.

The equipment is intended for battery R&D electrode preparation, including work where electrode tabs must be included in the cut profile. Its compact structure and compressed-air operation allow installation inside a glovebox, using gas consistent with the glovebox environment. Interchangeable die tooling also supports different electrode geometries and customer-specific maximum cutting-size requirements.

A four-guide-column structure provides smooth, accurate vertical movement through the cutting cycle. The unit is engineered to avoid common electrode-edge defects, including burrs, powder shedding, and indentation marks. With a normal-use die life of at least 30,000 cycles, robust motion components, and a maximum punching pressure of 1 T, this system provides dependable daily cutting performance for demanding laboratory environments.

Key Features

• Controlled Burr Performance: The equipment is specified for vertical burrs of no more than 12 μm and horizontal burrs of no more than 20 μm. This controlled cutting result helps laboratories prepare electrodes with cleaner edges for consistent downstream cell assembly.

• High Punching Accuracy: Punching accuracy of ±0.1 mm supports repeatable electrode dimensions and reliable alignment of sheet material, cut profiles, and electrode tabs. The precision is particularly relevant when producing comparable samples across repeated development runs.

• Glovebox-Compatible Pneumatic Operation: The compact unit can be placed inside a glovebox. It operates from 0.5 MPa compressed gas, with the gas selected to match the glovebox environment when installed internally.

• Long-Life Interchangeable Dies: Die tooling is designed for a normal-use life of at least 30,000 operations. Dies can be changed conveniently and quickly, allowing laboratories to adapt the equipment to different cutting profiles without an unnecessarily complex changeover process.

• Four-Column Guided Construction: Four guide columns maintain smooth upper-and-lower sliding movement and provide high guiding precision during the punching stroke. This mechanical arrangement supports stable die alignment and consistent cut formation.

• Upward Pneumatic Cutting Stroke: After the operator presses the start valve, the cylinder drives the die-cutting knife assembly upward to cut the electrode automatically. The 35 mm die-cutting stroke provides a defined mechanical travel for the forming operation.

• Electrode Surface Protection: The cutting process is designed to produce formed electrodes without burrs, powder loss, or indentation defects. Preserving the sheet condition is important when preparing coated electrode materials for later handling and assembly.

• Practical Laboratory Footprint: With overall dimensions of L350 mm × W230 mm × H300 mm and a weight of 32 kg, the unit is sized for laboratory installation where workspace and glovebox capacity are relevant considerations.

• Quality Motion and Pneumatic Components: The equipment incorporates Airtac pneumatic components and NSK/Taiwan Baolong bearing motion components. These specified elements support smooth movement and reliable pneumatic actuation within the machine structure.

• Serviceable Mechanical Design: The cutting knife plate and guide assemblies can be cleaned routinely, while linear ball-guide-column and guide-sleeve movement areas can be lubricated. This accessible maintenance approach helps sustain smooth operation over extended use.
