AI Technical Summary
Existing technologies for inspecting metal mobile phone casings suffer from low efficiency, high subjectivity, and susceptibility to fatigue-induced missed detections. Furthermore, automated optical inspection equipment has poor adaptability to highly reflective metal surfaces, making it difficult to fully cover all surfaces of the casing and resulting in blind spots in the inspection.
Multiple image acquisition components are used to acquire surface images of the metal mobile phone casing from multiple angles. Combined with a telecentric lens, perspective distortion is eliminated. A combination of ring light source and coaxial light source is used to provide uniform illumination. The positioning mechanism fixes the casing with the lifting support platform through the gap of the conveyor belt. The flipping mechanism realizes double-sided detection. The dust removal mechanism removes dust adsorbed by static electricity. The sorting mechanism automatically separates good products from defective products.
It enables multi-angle, blind-spot-free detection of metal mobile phone casings, improving detection accuracy and efficiency, eliminating specular reflection interference from highly reflective surfaces, and ensuring imaging quality and reliability of detection results.
