Core Processes
· Laser Welding System：Fiber laser source with galvanometer scanning or flying optics enables low-spatter, deep-penetration welding on busbars and terminals. Ensures stable tensile strength and minimal heat-affected zone.
· Automatic Screw Locking Unit：Multi-axis servo-controlled screw drivers with torque accuracy within ±3%, assisted by vision-guided positioning to prevent cross-threading or insufficient torque, guaranteeing reliable busbar connections.
· Intelligent Conveying & Positioning：Speed chain or roller conveyor combined with precision fixtures ensures accurate cell spacing, compatible with various module sizes, with changeover time ≤ 30 minutes.
Technical Advantages
· High Yield Guarantee：In-line CCD inspection and weld quality monitoring system provides real-time feedback. Welding yield ≥99.5%, screw locking yield ≥99.8%.
· Full Traceability：Each cell is assigned a unique QR code; all production data (welding parameters, torque values, voltage & IR) are uploaded to the MES system for full lifecycle traceability.
· Modular Design：Each station operates independently with individual start/stop controls, easy maintenance, and supports future flexible capacity expansion.
