Semi-automatic Lithium-ion Battery Pack Assembly Line For UAV/Drone Battery
This semi-automatic assembly line is specifically engineered for high-performance UAV (Unmanned Aerial Vehicle)/Drone battery packs. Given the unique requirements of drone batteries—high discharge rates, lightweight construction, and extreme reliability—our production line integrates precision cell capacity grading, sorting, and advanced welding technologies to ensure every pack meets rigorous flight safety standards.
Assembly Process Flow
Cell capacity grading → Insulation paper pasting → Cell voltage & IR sorting → CCD testing → Battery pack spot welding → BMS testing → Battery pack comprehensive testing → Shrink film packaging → Inkjet code printing → Battery pack aging testing
Main Process Sections
- Cell Testing & Sorting: High-precision OCV (Open Circuit Voltage) and IR (Internal Resistance) testing to ensure cell consistency, which is critical for drone flight stability.
- Automatic Insulation Paper Pasting: Protects the positive terminal of cylindrical cells to prevent short circuits during high-vibration flight.
- CCD Polarity Inspection: Visual recognition system to prevent manual misplacement of cells before welding.
- Precision Spot Welding: Equipped with high-frequency DC or Transistor welding power sources for consistent, low-resistance connections.
- BMS Testing & Integration: Verifies the protection board's functions (overcharge, over-discharge, overcurrent).
- Battery Pack Comprehensive Testing: Final verification of voltage, resistance, and discharge performance.
Key Applications
- Agricultural Spraying Drones
- FPV Racing & Photography Drones
- Industrial Inspection UAVs
- Delivery & Logistics Drones
Key Features & Advantages
- Modular & Flexible Design: Standalone machines allow customizable configurations to meet diverse process requirements.
- Easy Operation & Maintenance: Simple machine structure enables quick troubleshooting, low maintenance costs, and short operator training cycles.
- Flexible Production: Easy to switch between different pack configurations (6S, 12S, 14S) and cell types (18650, 21700, or Pouch cells).
- Data Traceability: Support for MES system integration to track every cell's data for quality control.
- Lower Initial Investment: Compared to fully automated lines, the semi-automatic solution requires lower capital expenditure, ideal for small-to-medium batch production.
- Scalable & Upgradable: Supports phased capacity expansion and future upgrades to full automation, reducing initial investment risks.
