Patent number: 11796308Abstract: The imaging camera includes the high-sensitivity pixel with the spectral sensitivity characteristic having high sensitivity to a light of the wavelength to be irradiated to the solder (target), and the low-sensitivity pixel with the spectral sensitivity characteristic having low sensitivity to this light. This allows the pattern light reflected in the high-reflection area of the surface of the solder to be converted to an appropriate pixel value using the low-sensitivity pixel, while allowing the pattern light reflected in the low-reflection area of the surface of the solder to be converted to an appropriate pixel value using the high-sensitivity pixel. Namely, both the pattern lights reflected in the high-reflection area and the low-sensitivity pixel can be converted to appropriate pixel values. In this way, even if the solder has both the high-reflection area and the low-sensitivity pixel, acquisition of accurate pixel values is allowed for both of these areas.Type: GrantFiled: August 24, 2018Date of Patent: October 24, 2023Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventor: Nobuaki Tabata

Patent number: 11795004Abstract: A conveyor table transfer apparatus includes a link mechanism connects the drive member driven by a motor (drive source) and a movable member supporting the movable linear conveyor. The link mechanism has one or more degrees of freedom. The degree of freedom of the link mechanism causes the link mechanism to bend in response to a degree of parallelization between the linear-motion guide rail and the linear-motion guide rail, making it possible to suppress load to be applied to the drive member or the movable member. As a result, it becomes possible to move the movable linear conveyor smoothly without requiring precise adjustment in mounting of the drive member and the movable member on the linear-motion guide rail and the linear-motion guide rail respectively.Type: GrantFiled: May 15, 2020Date of Patent: October 24, 2023Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventor: Kota Yamaguchi
