  • Patent number: 10784129
    Abstract: A mounting device in which a loading distance separating adjacent characteristic components are lined up side by side is shorter than separation distance between suction nozzle and mark camera, processing to image characteristic component by mark camera and recognize the position of characteristic component is performed consecutively or in one batch. With the mounting device, because mounting head is moved a loading distance that is shorter than the separation distance between suction nozzle and mark camera and image processing is performed consecutively or in one batch, the movement distance of mounting head is shorter.
