Description
Automatic Die Cutting Machine – High-Speed Electrode Cutter for Pouch Cell Batteries
This Automatic Die Cutting Machine is specifically designed for punching positive and negative electrodes of pouch cell batteries. It serves as the front-end process for stacking machines, delivering high speed, minimal burr formation, and very low powder drop. The machine processes roll-fed electrode material and outputs cut electrodes via PET film with automatic cutting, followed by manual collection.
Key Features:
- High Efficiency: 20–30 electrodes per minute production speed.
- Precision Cutting: Cutting accuracy ±0.15mm, positioning accuracy ±0.5mm with sensor-based error compensation.
- Low Burr: Burr length ≤30μm for clean electrode edges.
- Flexible Die Change: Interchangeable punching knives for different electrode sizes; max knife template 500×400mm.
- Durable Tooling: Punching knife life >15,000 times.
- Automated Control: PLC with touch screen, automatic counting, error display, and parameter setting.
- Integrated Waste Management: Waste collection box for punched scrap.
- High Reliability: Product qualification rate ≥98% (machine-related), equipment utilization ≥95%.
Working Principle:
The machine adopts an automatic continuous die-cutting structure:
- Roll electrode unwinding with active drive and proximity switch control.
- Photoelectric correction actuator ensures stable material transport and feeding accuracy.
- Motor-driven crankshaft operates the knife seat; main traction driven by high-precision servo motor.
- Tension adjustable with tension motor control.
- Waste automatically collected; PET brush powder dust removal keeps electrodes clean.
Main Components:
- Electrode discharge mechanism with correction
- Electrode tension mechanism
- Electrode and PET synchronous feeding
- Precision punching mechanism
- Waste collection agency
- PET brush powder dust removal
- Electric control system (PLC touch screen)
Applications:
- Pouch cell lithium battery electrode cutting
- Pre-process for stacking machines
- High-volume electrode production lines
- R&D and pilot-scale battery manufacturing
