AI Technical Summary

Technical Problem

Existing display defect detection devices are not convenient for continuous detection and diversion transportation, and the detection environment lacks anti-interference measures, resulting in insufficient detection accuracy.

Method used

Design a machine vision-based display defect detection device, comprising a housing, a dust collection box, a conveyor belt, a detection table, and a robotic arm, forming a relatively closed detection environment. The display screen is transported by the conveyor belt and the defects are diverted by the robotic arm. Dust is removed by a fan and an air guide box, ensuring the continuity and accuracy of the detection.

Benefits of technology

It enables continuous detection and defect separation of displays, reduces external interference, and improves detection accuracy and efficiency.
