Client Background
A leading electric vehicle (EV) battery manufacturer in China needed an ultra-high-speed busbar processing solution to meet surging demand for lithium-ion battery packs. Their existing manual process was slow, inconsistent, and unable to keep up with production targets.
Challenges & Requirements
1. Mass Production Speed – Required processing over 5,000 busbars per day with minimal downtime.
2. Ultra-Precise Tolerances – Busbars needed ±0.1mm accuracy to ensure proper current flow in battery modules.
3. Flexible Material Handling – Needed to process thin, flexible copper busbars (1mm–6mm) without deformation.
4. Clean & Burr-Free Cutting – Any burrs or micro-cracks could lead to battery failures, so laser cutting was preferred.
5. Integration with Robotic Assembly – The machine had to sync with automated battery pack assembly lines.
Our Solution: Automated Laser Busbar Processing System
We developed a fully automated, high-speed laser cutting and bending machine with:
✔ Fiber Laser Cutting – Burr-free, high-precision cuts at 20 meters/minute with auto-edge detection.
✔ Servo-Driven Bending Unit – Multi-axis bending with ±0.05mm repeatability for complex shapes.
✔ Automated Conveyor & Sorting – Robotic pick-and-place for seamless transfer to the next assembly stage.
✔ AI-Based Vision Inspection – Real-time defect detection (cracks, misalignment) with 99.9% accuracy.
✔ Cloud-Based Monitoring – Remote diagnostics, production analytics, and predictive maintenance.
Results & Benefits
✅ 4x Faster Production – Output increased from 1,200 to 5,000+ busbars/day.
✅ Zero Rejects – Laser precision eliminated material waste and defects.
✅ 24/7 Unmanned Operation – Reduced labor costs by 60%.
✅ Seamless EV Battery Integration – Enabled the client to scale production for 500,000+ EV batteries/year.
