Automatic Electrode Die-Cutting Machine XN-PDCA-350

Name: Automatic Electrode Die-Cutting Machine XN-PDCA-350

Equipment Type: Floor-Standing Fully Automatic Roll-to-Cut Electrode Die-Cutting Machine

Product Code: XN-PDCA-350

Brand: Xnergy

Product Introduction:

Automatic Electrode Die-Cutting Machine XN-PDCA-350 is a floor-standing fully automatic die-cutting system that integrates the complete roll-to-cut electrode-shaping workflow into one continuous machine. Coiled electrode strip is loaded onto a servo-tensioned pneumatic unwind shaft, automatically edge-corrected during feeding, advanced by a stepper-driven traction system at programmable step length, die-cut on a modular die station, and discharged via a circulating conveyor belt — while the scrap is separated and collected by an automatic recovery system. The PLC + touchscreen interface supports both automatic and manual operating modes, and an aluminum-frame enclosure with acrylic guard and infrared light grating protects the operator.

Working Principle:

A coiled electrode strip is mounted on the pneumatic expanding shaft. Servo-tensioned unwinding feeds the strip through edge-guide rollers (automatic correction) and into the stepper-driven traction zone, which advances the strip by a programmable step length to the die station. The upper die descends to cut the strip; finished electrodes are conveyed out on the belt while scrap is collected automatically. The cycle repeats continuously under PLC control.

Technical Specifications:

Application Areas:

XN-PDCA-350 is suitable for:

Fully automatic die-cutting of lithium-ion battery cathode and anode electrode strip to pouch- and prismatic-cell shapes with integrated tabs
Continuous production of shaped electrodes from coiled stock at pilot- and production-scale volumes
Workflows requiring automated scrap recovery and consistent feed precision
Pouch-cell and prismatic-cell electrode manufacturing where manual sheet handling is the bottleneck

Maintenance:

Clean the equipment regularly with a soft cloth lightly moistened with alcohol
Lubricate moving parts periodically to ensure smooth operation
If the equipment is not used for an extended period, clean the moving surfaces and apply a protective anti-rust coating
Periodically inspect screws, nuts, pins, and other fasteners to prevent loosening
Inspect the die regularly and replace at end of life to maintain burr specification

Safety Notes:

Do not bypass the infrared light grating, enclosure, or safety guard
Do not place hands or other body parts in the die work area or feed path during operation
Operation should be performed by a single trained operator
Disassembly should only be performed by qualified technicians
Ensure compressed air and power supplies are stable within the specified ranges before operation

Specifications are provided for reference. Custom die tooling and shapes are specified at order time. Die life depends on die quality and setup precision.

Note: Specifications listed above are typical and for reference only. Actual die-cutting performance depends on electrode strip thickness, coating composition, die condition, and feed-line stability. XN-PDCA-350 is the production-line member of Xnergy’s die-cutting range — and it is structurally a different machine from the benchtop semi-automatic models, not just a larger version. The integrated automation chain (unwind, edge-guide, stepper feed, die-cut, conveyor, scrap recovery) means a single operator can run continuous shifts without per-sheet handling, which is the key economic difference once electrode volumes exceed what a semi-auto operator can keep up with at 800–2000 pcs/h. Users with smaller volumes or who need direct sheet feed rather than roll feed should look at XN-PDC-350 (320 × 240 mm sheet die-cutter, 5-ton force) or XN-PDC-280 (280 × 180 mm sheet die-cutter, 3-ton force) instead. For glovebox-compatible single-stroke prototype die-cutting with no electrical components, the XN-PDC-120 remains the appropriate alternative. Upstream coil supply for XN-PDCA-350 is typically produced via the Slot-Die Coating System XN-SDC with width slitting on the XN-CSER-500 roll-to-roll slitter to match the 320 mm web width.
