Key Technical Advantages
High-Speed Dual Gantry Independent Operation
The machine employs a dual gantry, dual-drive, dual-gripper design where each gripper works independently. This eliminates the need to wait for both material supply tracks to be fully loaded before operation, maximizing production efficiency. Even when a tabber stringer on one side experiences a fault, the layup machine continues normal production from the other side without interruption.
Ultra-Precise Linear Motor Drive System
The main axis utilizes linear motor drive technology delivering repeat positioning accuracy of 0.01mm. This ensures exceptional speed, precision, stability, and reliability while requiring virtually no maintenance. Combined with servo 8-point glass positioning at ±0.1mm accuracy, the system guarantees consistently precise string placement.
Advanced 3-Camera Vision Positioning System
Three 5-megapixel industrial cameras with 1.67μm × 1.67μm pixel size provide real-time vision-guided cell string positioning. The cumulative dimensional chain error across all strings remains below 0.3mm, ensuring every module meets stringent quality standards.
Intelligent Vacuum Handling with Safety Detection
The cell string gripping fixtures feature vacuum detection functionality that effectively prevents cell drops during the pick-and-place process. Imported silicone vacuum cups ensure cell strings are handled without leaving any marks or damage, maintaining cell integrity throughout the layup process.
Comprehensive Breakage Protection
With a breakage rate of ≤0.015% and placement yield of ≥99% (excluding incoming material defects), the WS-CL80D significantly reduces material waste and production costs. The gentle handling system is specifically designed to protect fragile solar cells during high-speed operations.
Smart Factory Ready with MES Integration
The equipment features a dedicated Ethernet port and provides full data access including cycle time, capacity, running time, downtime, material status, and more. Complete MES integration capability supports material traceability and production management, making the WS-CL80D ready for Industry 4.0 smart factory environments.
Flexible Multi-Format Recipe Management
The PC control system stores multiple module layout recipes, enabling rapid switching between different module formats. The intuitive human-machine interface supports both manual and automatic operation modes, one-click factory reset, and multi-level password protection for secure operation.
Wide Compatibility Range
Supporting glass sizes from 1600-2600mm on the long side and 980-1450mm on the short side, with cell compatibility from 18X×18X to 230×230mm, and module layouts from 48 to 78 half-cells, the WS-CL80D accommodates virtually all mainstream MBB half-cell module configurations.
