Abstract

PURPOSE: To establish the non-contact type inspection unit highly reliable, which can surely select the propriety of the screw pitch with good efficiency with a simple constitution, by providing the light source emitting light beam on the screw and photo detector receiving the reflected light.
CONSTITUTION: When a plurality of screws 3 are arranged and carried with the parallel material 1 sequentially, positioning is made to the detected position with the position sensor 2, light beam is emitted from the light source 4 to the screw, and the reflected light is received to the photo detector 5. Since the light beam 7 emits perpendicular to the surface of screw tooth and enters the photo detector 5 by tilting the direction of emission by 30 degrees to the axis of the screw 3, since the angle of screw tooth are almost 60 degrees. If no screw tooth are graved, the light beam 7 is reflected upward on the surface of screw, not entered to the photo detector 5, and the deficiency of screw can be detected.
