Patent number: 11893723Abstract: Provided is a technique that allows an operator or the like to easily perceive a tendency of defects which are present in molds or patterns. A display device displays a result of inspection of a plurality of molds or a plurality of patterns which are inspection target objects. The display device classifies the inspection target objects into a plurality of groups, generates, for each of the plurality of groups, a heat map image from a result of defect inspection of one or more of inspection target objects which are classified into the each of the plurality of groups, the heat map image representing a spatial distribution of defect occurrence frequencies; and causes a display to display one or more of the heat map images generated, the one or more heat map images corresponding to one or more groups specified by a user from among the plurality of groups.Type: GrantFiled: March 26, 2021Date of Patent: February 6, 2024Assignee: SINTOKOGIO, LTD.Inventors: Kazuhiro Ota, Takeshi Sonohara, Hiroki Matsuoka, Takehiro Sugino

Patent number: 11810286Abstract: Provided is the technique that allows an operator or the like to easily grasp a defect contained in a mold. A display control device is configured to carry out: a determination process in which a feature amount of each of defects contained in a mold is determined with reference to an image obtained by image capture of a mold; and a display process in which the image is displayed on a display such that each of the defects in the image is emphasized by a method which is determined according to the determined feature amount.Type: GrantFiled: March 26, 2021Date of Patent: November 7, 2023Assignee: SINTOKOGIO, LTD.Inventors: Kazuhiro Ota, Takeshi Sonohara

Patent number: 11802842Abstract: Provided is the technique that allows an operator or the like to grasp a failure of a mold to be worked in the work area. An inspecting device inspects each of a plurality of molds conveyed along a conveyance path with use of image data generated by a sensor that captures an image of each of the plurality of molds. A display control device is configured to carry out: a storage process in which inspection results of the individual molds are stored in a memory; a determination process in which one or more molds satisfying a predetermined condition of a positional relation to a display are determined from among the plurality of molds conveyed along the conveyance path; and a display control process in which one or more inspection results of the respective one or more molds having been determined in the determination process are displayed on the display.Type: GrantFiled: March 26, 2021Date of Patent: October 31, 2023Assignee: SINTOKOGIO, LTD.Inventors: Kazuhiro Ota, Takeshi Sonohara

Publication number: 20220207684Abstract: The purpose of the present invention is to improve accuracy in inspection of an appearance of a mold. The inspection device includes at least one processor for performing an inspection step of inspecting an appearance of a mold using a learned model constructed by machine learning. Input into the learned model includes an inspection image obtained by imaging the appearance of the mold. Output from the learned model is information indicating an inspection result of the appearance of the mold.Type: ApplicationFiled: November 4, 2021Publication date: June 30, 2022Applicant: SINTOKOGIO, LTD.Inventors: Takehiro SUGINO, Takeshi SONOHARA

Patent number: 11158041Abstract: An inspection device is a device that inspects the appearance of a target, including: an imaging device configured to image the target from a first direction; an illuminating unit configured to apply light to the target; and a controller configured to acquire a first inspection image by causing the imaging device to image the target to which light is applied from a first position, to acquire a second inspection image by causing the imaging device to image the target to which light is applied from a second position, and to inspect an appearance of the target based on the first inspection image, the second inspection image, and a reference image. The first position and the second position overlap each other when viewed from the first direction.Type: GrantFiled: May 10, 2018Date of Patent: October 26, 2021Assignee: SINTOKOGIO, LTD.Inventors: Kazuhiro Ota, Tsutomu Seki, Yoshimitsu Ichino, Junichi Iwasaki, Takeshi Sonohara, Ryuichi Kawakami, Tatsuya Aoki
