Laser Automation Solution for Battery lid Side Welding
Release time: 2021-10-26
Laser Automation Solution for Battery lid Side Welding
1. Customer Requirements
1.1 Equipment Requirements
The customer requires a fully automated square power battery welding and inspection production line with the following functions:
- Automatic transfer after battery cell casing feeding.
Laser welding for battery sealing.
- Automated insulation resistance testing.
- Automated leak testing (airtightness).
- Barcode labeling.
Welding standards: Smooth, strong welds with no cold joints.
1.2 Feeding Requirements
- Battery cells are pre-loaded into casings with aligned lids and frames.
- lids must fit flush with casing edges.
Material: Aluminum (Al).
Precision tolerance: Width/thickness ≤ ±0.1mm; lid-casing alignment must be precise.
2. Technical Solution
The production line includes:
2 laser welding machines
2 testing stations
Automated conveyor system for seamless battery flow.
Line dimensions: ~11,000 × 2,500 × 2,000mm (L×W×H).
2.1 Welding Process
Fiber laser system with dual workstations for simultaneous welding.
2 robotic arms for loading/unloading (boosts efficiency).
CCD vision positioning ensures precision (≤ ±0.05mm).
Welding specs:
- Speed: ≥40mm/s
- Penetration: 0.4–0.7mm
- Weld width: 0.8–1.2mm
Fume extraction system minimizes pollution.
2.2 Testing Process
- Post-weld short-circuit and leak tests.
- Automated barcode labeling for traceability.
- Automatic rejection of defective units.
Vacuum testing for airtightness compliance.
- All test data stored with barcode linkage for smart management.
3. Key Features
1. Dual-station laser welding for high throughput.
2. Separate loading/welding zones for safety.
3. High-precision robotic handling (minimizes manual work).
4. Integrated fume purification meets environmental standards.
4. Technical Specifications
Line dimensions: 11,000 × 2,600 × 2,000mm
