The invention relates to a material appearance automatic detecting device. The material appearance automatic detecting device comprises a transferring mechanism, and a tray clamp and a detecting module which are connected with the transferring mechanism respectively via a mobile module; the detecting module comprises an imaging device and a detecting clamp; the transferring mechanism is arranged on an X axis mobile module; the tray clamp and the detecting clamp are arranged on corresponding Y axis mobile modules respectively; the detecting clamp is arranged on another X axis mobile module in a overlapped manner; the transferring mechanism is provided with two tray hands; a material hand is arranged between the two tray hands. According to the material appearance automatic detecting device, the material appearance automatic detecting device is provided with the tray clamp and a material clamp, and the tray clamp and the material clamp are connected via the transferring mechanism, so that simultaneous detecting and subpackaging can be realized, and interacting of working efficiency of detecting with working efficiency of subpackaging is not caused; the transferring mechanism is arranged on the X axis mobile module, so that joining of the transferring mechanism to the position of the tray clamp and the position of the detecting module is realized; the tray clamp and the mobile module are arranged on the Y axis mobile modules respectively, so that connecting and position cooperation with the transferring mechanism are convenient to realize.
