  • Patent number: 11357149
    Abstract: A component orientation determination data creation device for creating component orientation determination data used in a component orientation determination system that determines an orientation of the component by comparing a brightness value of a determination region specified in the component orientation determination data within an image of the component captured by a camera with a determination threshold. A difference image between an image of the component in a correct orientation and an image of the component in another orientation is calculated by acquiring multiple images of the component in different orientations by changing the orientation with respect to the camera of the component that is the target for the component orientation determination data creation.

  • Publication number: 20220145985
    Abstract: An abnormality of a gear is more appropriately predicted. An abnormality prediction device of the present disclosure is used in a feeding device including a driving section, a gear connected to the driving section, and a detection section configured to detect a position of a medium fed in accordance with driving of the gear, and intermittently feeding the medium. The abnormality prediction device acquires detection information regarding a feed amount of the medium based on the position of the medium detected over time by the detection section, decomposes the acquired detection information into a trend component regarding a moving average of the gear, a cycle component based on a cycle of the gear, and a random component obtained by excluding the trend component and the cycle component, obtains an abnormality level of the gear based on the cycle component obtained by the decomposition, and outputs the obtained abnormality level.

  • Patent number: 11210764
    Abstract: An apparatus for performing work on a substrate includes an image processing device acquiring multiple images captured at different positions by performing imaging multiple times after a camera has been moved by a moving device such that a reference mark of a circuit board is within a range inside a field of view of the camera, creating a super resolution image using multi-frame super resolution processing, and recognizing the reference mark. The image processing device performs candidate region search processing of processing the image captured initially to search for a region within the image including a portion that has a possibility of being the reference mark as a candidate region after completion of the initial imaging, performs multi-frame super resolution processing on the candidate region after completion of final image capturing, creates a super resolution image of the candidate region, and recognizes the reference mark.

  • Patent number: 10869421
    Abstract: 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.
