Magnetic shoe appearance defect detection structure

The utility model provides a magnetic shoe appearance defect detection structure. The device comprises a camera used for shooting magnetic shoe images, a direct illumination lamp and a diffusion lampwhich are coaxial are arranged between the camera and a magnetic shoe to be detected, and the direct illumination lamp comprises a parallel light source which is incident in the direction perpendicular to the optical axis of the camera and a reflector which reflects light emitted by the parallel light source to be parallel to and coincide with the optical axis of the camera; the diffusion lamp comprises an arc-shaped cover with the upper end and the lower end being open, and an annular light source which is installed at the bottom of the arc-shaped cover and irradiates the inner wall of the arc-shaped cover. According to the technical scheme of the utility model, the illumination mode is adopted. According to the invention, the periphery and the upper surface of the currently placed magnetic tile are completely fr
