Appearance detection device

The utility model discloses an appearance detection device, including the speculum, the work piece below is being waited to detect in the setting of speculum looks interval, the speculum top is provided with imaging mechanism just imaging mechanism is located and waits to detect the work piece top, the speculum lateral part is provided with light source generator, light source generator is used for radiation beam to waiting to detect the work piece. The utility model provides a when the scheme is specifically implemented, wait that the cable that detects passes through suspension such as peripheral hardware carousel in the speculum top, at this moment, imaging mechanism can directly shoot the condition of cable upper surface, and in the speculum reached the condition reflection of cable lower surface imaging mechanism, simultaneously, light source generator can illuminate the cable by radiation beam, ensures imaging mechanism's image quality. So, pass through in proper order speculum when top when the cable,
