Patent number: 10932401Abstract: There is provided a component mounting machine in which when detecting a lowermost end position of a component sucked by a suction nozzle, a lower edge position of the component is detected at predetermined intervals from a left side and a right side using the lowermost end position as a reference. The component mounting machine derives an approximate straight line obtained by approximating multiple lower edge positions detected from the side having a larger detection number and the lowermost end position and an angle of the approximate straight line is detected as the suction angle of the component. Accordingly, the component mounting machine can appropriately detect the suction angle of the component with a simple process and correctly determine the suction posture of the component.Type: GrantFiled: July 23, 2015Date of Patent: February 23, 2021Assignee: FUJI CORPORATIONInventors: Yusuke Yamakage, Yoshiyuki Fukaya

Patent number: 10869421Abstract: A mounting device sets a processing region for super-resolution processing based on an approximate position of a main body portion of a component included in a mark image for use in obtaining a position of a fiducial mark and then performs super-resolution processing. Thus, the processing region for super-resolution processing can be appropriately set and prevented from becoming larger than necessary with respect to the main body portion of the component. Further, the processing region for super-resolution processing is determined using the mark image captured under an imaging condition different from that for the component image for use in super-resolution processing. Thus, the processing region can be appropriately set while the component image is kept under an imaging condition suitable for super-resolution processing. Therefore, the processing region for performing super-resolution processing can be set more appropriately, and the super-resolution processing can be efficiently performed.Type: GrantFiled: January 19, 2016Date of Patent: December 15, 2020Assignee: FUJI CORPORATIONInventors: Masafumi Amano, Kazuya Kotani, Ryohei Kamio, Yusuke Yamakage
