Abstract:
1. A component mounting device comprising: a substrate conveyance path that conveys a substrate while supporting the substrate from below; a light projector that projects inspection light in a direction orthogonal to a direction of conveyance of the substrate by the substrate conveyance path and a light receiver that receives the inspection light projected by the light projector; an end detection unit which, according to a change in an amount of inspection light received by the light receiver, detects that an end of the substrate conveyed by the substrate conveyance path in a direction parallel to the substrate conveyance path or an end of a portion projecting outside from an end of a component mounted on the substrate in a direction parallel to the substrate conveyance path for the substrate has reached the inspection light; a substrate positioning control unit which immediately halts operation of the substrate conveyance path when the end detection unit detects that the end of the substrate has reached the inspection light and which, when the end detection unit detects that the end of the component mounted on the substrate has reached the inspection light, activates the substrate conveyance path such that the substrate moves in a projecting direction of the projecting portion over a distance equivalent to a projection length of the projecting portion reached the inspection light and subsequently halts the substrate conveyance path, thereby positioning the substrate; and a mounting section that mounts components on the substrate positioned by the substrate positioning control unit.
