  • Patent number: 10716250
    Abstract: A component mounting apparatus is provided with a controller that controls a mounting head. The mounting head is provided with a nozzle holder, a nozzle that is elastically supported to be movable up and down with respect to the nozzle holder, a flange that is provided at a position that is offset from the central axis of the nozzle, and a second engaging section that is able to move the nozzle downward by engaging with the flange and pressing down the flange against the elastic force of a nozzle spring. The controller measures in advance the deviation amount of the tip position of the nozzle between before and after the second engaging section moves the nozzle downward and controls the mounting head so as to suck the component and mount the component on the board taking the deviation amount into account.

  • Patent number: 10334770
    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.
