Description
Automatic Hardware Die Cutting Machine – High-Speed Roll-to-Roll Electrode Cutter with CCD Inspection
The Automatic Hardware Die Cutting Machine is a high-precision, high-speed roll-to-roll system designed for forming lithium battery electrodes. Using customized separate dies, this equipment ensures precise electrode dimensions while preventing separator puncture and internal short circuits. Integrated with advanced inspection and dust removal systems, it delivers exceptional product quality and yield for large-scale battery manufacturing.
Working Principle:
The machine operates on a roll-to-roll basis with unwinding and rewinding mechanisms. Electrode materials pass through an EPC correction system for precise alignment before entering the die cutting station. The punch die features a press plate evenly distributed around it, guided by numerous precision guide columns to minimize powder drop at cut edges. After cutting, a CCD inspection system detects defects and automatically removes non-conforming electrodes. Acceptable electrodes are collected in bins for manual packaging.
Key Features:
- High-Speed Production: Operating speed ≥60-80 PPM for efficient manufacturing.
- Precision Die Cutting: Customized dies ensure exact electrode dimensions; tab width/height tolerance ±0.15mm.
- Exceptional Die Life: Each die repair supports ≥1 million cuts; repairable ≥10 times for total lifespan ≥10 million cuts.
- Advanced Inspection: CCD inspection with ±0.1mm accuracy, 0% miss rate, ≤3% false alarm rate.
- Dust Control: Negative pressure and FFU dust removal system maintains clean environment.
- Edge Powder Control: Press plate and precision guide columns minimize electrode edge powder loss.
- High Yield: Product qualification rate ≥99.5%, good product rate ≥95%.
- Robust Construction: Equipment weight 7000kg for stable, vibration-free operation.
Applications:
- High-volume lithium-ion battery electrode production
- Cathode and anode die cutting for cylindrical, prismatic, and pouch cells
- Precision tab forming
- Automated battery manufacturing lines
