AI Technical Summary
Traditional grinding machines use fixed light sources and camera layouts for visual inspection, which cannot adjust the illumination angle according to the material and shape of the workpiece. This results in reflections or blind spots, affecting the clarity of image acquisition and the accuracy of inspection. Furthermore, the lack of flexible adjustment mechanisms means that they cannot automatically compensate for errors caused by workpiece position shifts or changes in processing angles, thus reducing inspection efficiency.
By aligning the centerline of the backlight with the optical centerline of the lens, and coordinating the reciprocating motion of the front light source along the optical axis, combined with the multi-angle adjustment of the rotating and clamping motion sources, uniform illumination of the workpiece and dynamic adjustment of the vision inspection components are achieved, automatically compensating for inspection errors.
It enables accurate identification of minute defects and dimensional deviations on the workpiece surface, improves image acquisition clarity and detection accuracy, increases detection efficiency and automation, and reduces manual calibration costs.
