Embodiment Construction
[0026] Such as figure 1 As shown, a resin lens film leakage defect detection device includes a dark box 1, a rotating motor 2, a fixed frame 3, a motion controller 4, a main controller 5, a camera 6, a light source 7, a lens fixed frame 8, and a background plate 9. The rotating motor 2 is fixed on the top of the darkroom 1, and is driven and controlled by the motion controller 4 to execute the rotation command, and its motion parameters are sent by the main controller 4 to the motion controller 4 through serial communication; the fixed frame 3 and the rotating motor 2 are connected through a keyway Connection, its size and structure are determined by the pose relationship between the camera 6 and the light source 7 and the lens; the camera 5 and the light source 7 are relatively installed, wherein the plane of the camera 6 is at an oblique angle to the lens, and its field of view is larger than the diameter of the lens and the pixel The resolution meets the requirement for ide...
