Abstract
A component mounting machine includes a part camera in which a suction nozzle for sucking a component P and a fiducial mark are provided on a head, a sub-lens is installed in a visual field of a lens, the component is imaged through a main lens, and it is possible to image the fiducial mark through the lens and the sub-lens. Distortion correction values of the main lens portion are measured, distortion correction values of the sub-lens portion are measured, and the distortion correction values are stored in advance as a distortion correction table. During component mounting, when the component P which is sucked by the suction nozzle and the fiducial mark are imaged at the same time by the part camera, the obtained image is corrected using the distortion correction table, and a suction state of the component P is detected based on the corrected image.
