Patent number: 11272651Abstract: 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.Type: GrantFiled: September 28, 2017Date of Patent: March 8, 2022Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Kazushi Takama, Kunimune Komaike
