AI Technical Summary
Due to the optical incident angle and obstruction of the object shape, the existing laser profiler causes some reflected light to be unable to image, resulting in a defect in the point cloud pattern, which in turn affects the measurement of the outer contour size of the object.
Design a laser profiler that uses two laser receiving windows. The laser emitting window is located in the middle and the two receiving windows are located at both ends. This ensures that even if one receiving window is blocked, the other receiving window can still receive light and can be opened and closed through The protective mechanism protects the laser window from damage.
It effectively avoids imaging defects caused by occlusion by the shape of the object, ensures complete measurement of the outer contour of the object, and ensures the safety and reliability of the equipment through the protection mechanism.
