Description

Technical Field

[0001] The utility model relates to the technical field of 3D glass cover plate visual detection, in particular to a universal phase light detection device. Background Art

[0002] 3D mobile phone cover glass is increasingly used in the field of smart electronic displays, and product quality is becoming increasingly important in manufacturing. Therefore, defect detection of glass appearance is an essential part of the manufacturing process.

[0003] Currently, transparent glass inspection, a highly repetitive and intelligent task, is still commonly performed visually. However, in practice, workers are unable to perform inspections consistently and stably with their naked eyes. Consequently, inspection reliability is poor, efficiency is low, and subjectivity is high, making false detections and missed detections more likely. This also poses significant health risks for workers, who are susceptible to occupational diseases (e.g., eye problems). Furthermore, due to the transparency and high reflectivity of transparent glass, even conventional visual inspection methods cannot fully, accurately, and meticulously detect all types of defects. Incomplete inspections and low efficiency are technical limitations of existing glass defect inspection equipment.
