  • Patent number: 11272651
    Abstract: A component mounting device for mounting a component on a substrate includes a head unit, a driver to move the head unit on a stage, and a controller. The head unit includes a mounting head to hold the component and a stereo camera to capture a three-dimensional image of an object. The controller performs image capturing, calculating and mounting processes. The image capturing captures an image of a relevant area including a mounting point on the substrate by the stereo cameras before the component reaches the mounting point. The calculating calculates a correction amount with respect to X, Y and Z axes directions based on three-dimensional information on the relevant area with respect to the directions obtained in the image capturing process to mount the component on lands corresponding to the mounting point. The mounting includes correcting the mounting point based on the correction amount and mounting the component.

  • Patent number: 10674650
    Abstract: A component mounting device includes a controller that controls an imaging unit to image a predetermined region during a period from a time point at which a head finishes mounting a component at a mounting position to a time point at which the head completes upward movement from the mounting position, and acquires information about a height of the mounting position based on an imaging result of the predetermined region imaged by the imaging unit. The controller further determines whether or not the component has been successfully mounted at the mounting position based on the acquired information about the height of the mounting position.
