A suction device and a suction force adjustment method thereof are provided. An optical detection unit is disposed on a suction path of a suction pipe to detect an object flowing through the suction pipe. Physical features of the object are determined according to a sensing result of the optical detection unit. A suction force of a suction unit is regulated based on the physical features of the object.

Suction device and suction force adjustment method thereof

An optical detection device and a detection method thereof are provided. A linear light source provides a light curtain formed by multiple light beams, the light curtain is located on a transportation path of transporting an object to be detected. A sensor set senses the part of light beams not interrupted by the object to be detected, so as to generate a sensing signal with various strengths. A control circuit determines a physical characteristic, moving speed and position of the object to be detected according to the strength of the sensing signal.
