AI Technical Summary
Existing screen defect detection devices are cumbersome to operate during manual loading and unloading, which can easily damage or contaminate the screen and affect the accuracy of the detection results.
The automatic loading and unloading of screens is achieved by using a feeding assembly. Combined with a rotating tray and multiple workstations, it utilizes different light sources and inspection cameras to perform multi-angle and all-round defect detection, including the combined use of backlight source boards, coaxial light sources and low-angle light sources.
Reduce manual operation, lower the risk of screen damage, improve detection efficiency and accuracy, and ensure screen quality.
