The system achieves an overpass rate of 0.5% or less and a missing rate of absolute zero, ensuring every welding defect is detected. Real-time welding temperature images are saved as database files, providing full traceability for quality management. ###### Automatic Repair Welding Capability When the post-welding inspection system identifies abnormal solder joints, the machine automatically initiates repair welding without operator intervention. This eliminates virtual welding, welding leakage, and other defects, maintaining the 99.6% quality yield rate throughout continuous production. ###### High-Precision CCD Positioning System The CCD-based positioning system captures precise images of junction box locations with an accuracy of ±0.1mm. Combined with the R deviation correction function that handles junction box installation angle deviations of up to 30 degrees, the system ensures consistent welding quality regardless of minor placement variations. ###### Comprehensive Pre-welding and Post-welding Detection Pre-welding detection achieves 100% accuracy on lead wire pressing inspection, lead line deviation, and junction box installation deviation. Post-welding detection includes height measurement and visual inspection with automatic defective product identification and alarm functionality. ###### Advanced Automatic Tinning System The automatic tinning system provides precise tin amount control with ±0.1mm accuracy. Fast refueling takes less than 1 minute, and the system is compatible with tin wire diameters ranging from 0.5mm to 2mm with 1-3kg capacity. Intelligent alarms notify operators of material shortage or tin abnormalities. ###### Rapid Cycle Time and High Efficiency With a cycle time of 16 seconds or less and an opening probability exceeding 99.0%, the KS-01C maximizes production throughput. Quick version switching in under 10 minutes enables flexible production scheduling across different module types and configurations. ###### Robust Mechanical and Electrical Design The machine body utilizes European standard 40x80 aluminum or equivalent-strength welded steel frame construction for overall stability with zero vibration during operation. The welding head lifespan exceeds 35,000 cycles, and the overall equipment lifetime is rated at 10 years or more. ###### Full MES System Integration The KS-01C supports comprehensive MES interaction with data collection capabilities including component information, equipment operation parameters (temperature, test pictures, welding time, barcode information), consumables replacement records, maintenance records, and maintenance reminders. Data and pictures are stored for over 1 month with automatic coverage functionality. ###### User-Friendly HMI and Multi-level Control The human-machine interface supports formula-based mode switching with 50 formula storage capacity. The system includes 4 levels of user hierarchical permission control, fault state manual test with single step operation, simulation action capabilities, and automatic wire feeding speed calculation based on wire diameter, density, and tin amount parameters. ###### Complete Quality Assurance The machine ensures no diode short circuit or other short circuits during welding.
