This flow battery welding production line integrates multiple functions into one system. It can operate as a fully automated production line or be split into three independent work sections based on actual needs: an integrated cutting and welding machine, a leak testing unit, and an ultrasonic welding station for cover plates. This design enhances equipment flexibility and allows for targeted optimization and adjustments according to different process requirements.
PRODUCT DESCRIPTION
1. Cutting & Welding
●Enables precision cutting and welding of battery separators.
●Integrated cutting and welding design reduces material handling and enhances process continuity.
2. Quality Inspection
●In-Process Weld Inspection: Monitors weld bead formation in real time to ensure consistent welding quality.
●Leak Testing: Performs hermetic seal tests on welded flow field plates or stack components to prevent leakage risks.
●Ultrasonic Cover Welding: Executes precision welding of battery covers to ensure reliable packaging.
1. High-Precision Positioning
All electric axes utilize high-precision transmission and motion control, achieving a repeatability positioning accuracy of ±0.015mm. This precision is fundamental to achieving burr-free cutting, accurate weld trajectories, and reliable sealing.
2. Optimized Speed Control
To maintain micron-level processing precision, the maximum operating speed is limited to ≤600mm/s. This setting optimizes the balance between throughput and process stability, preventing positioning errors or quality degradation caused by excessive speed.
3. Installation Flatness
During setup, the flatness of the welding platen and clamping mechanisms is strictly maintained at ≤0.05mm/m². This high level of flatness ensures uniform pressure distribution during welding, resulting in consistent, high-quality seams that contribute to extended battery life.
●Modular Architecture: The system supports fully integrated, automated inline operation or can be easily decoupled for standalone use, offering flexibility for variable production demands.
●End-to-End Quality Control: Implements a closed-loop quality management system—from cutting and welding through online inspection and leak testing.
●High-Stiffness Construction: The machine frame and worktable are built from precision-machined, high-grade materials to ensure long-term accuracy and structural stability.
