AI Technical Summary
Existing LCD panel inspection equipment cannot simultaneously achieve full coverage inspection of micro-cracks on the surface and inside of LCD panels. It suffers from blind spots, low efficiency, high cost, poor accuracy, and cannot adapt to adaptive clamping and omnidirectional scanning of panels of different sizes.
Integrating infrared thermal imaging detection and fluorescence penetrant detection, combined with an adaptive positioning clamping structure, and using servo motors and cylinders in linkage, it achieves dual-dimensional crack detection, adapts to panels of different sizes, has a high degree of automation, and avoids blind spots in detection.
It enables simultaneous detection of closed microcracks inside LCD panels and open microcracks on the surface, reducing the microcrack missed rate, improving detection accuracy and efficiency, reducing equipment costs, and adapting to long-term mass production conditions.
