Publication number: 20240098958Abstract: A component confirmation device images components arranged in a pallet before the components are picked up to confirm the components based on a captured image of the components. A pick-and-place cycle is defined as a cycle from when a mounting head configured to pick up and mount a component on a board starts picking up a target component that is at least one of the components that the mounting head picks up at one time until when the mounting head mounts the target component on the board. At this time, the component confirmation device includes a moving section configured to move target equipment that is a first one of a lighting device configured to illuminate the target component and the pallet, relative to a second one of the lighting device and the pallet as required every pick-and-place cycle, in imaging of the target component.Type: ApplicationFiled: December 2, 2020Publication date: March 21, 2024Applicant: FUJI CORPORATIONInventors: Kohei SUGIHARA, Tomokatsu KUBOTA

Patent number: 11835207Abstract: A mounting device includes a control device. The control device images an imaging range which includes an illuminant of a light emitting component and acquires a light emitting component image when mounting the light emitting component which includes the illuminant onto a board. Next, the control device detects coordinates (illuminant detected center coordinates) of a center of the illuminant based on the light emitting component image. The control device performs the mounting of the light emitting component such that the light emitting component is held, the light emitting component moves over the board, and a center of the illuminant is positioned at predetermined coordinates on the board based on the illuminant detected center coordinates, without using information relating to an outer shape of the light emitting component which is based on the light emitting component image.Type: GrantFiled: December 30, 2021Date of Patent: December 5, 2023Assignee: FUJI CORPORATIONInventor: Kohei Sugihara

Patent number: 11751371Abstract: A component mounting device includes a control device configured to execute a recognition data creation process and a pickup process. In the recognition data creation process, the control device creates the recognition data by obtaining the angle information of the component, causing the imaging device to operate so as to image the component, and rotating the captured image so obtained to the reference angle based on the angle information. In the pickup process, the control device causes the head to operate so as to pick up the component after the supply state of the component is determined based on the captured image obtained by causing the imaging device to operate so as to image the component, the recognition data created in the recognition data creation process, and the angle information.Type: GrantFiled: January 18, 2019Date of Patent: September 5, 2023Assignee: FUJI CORPORATIONInventor: Kohei Sugihara

Patent number: 11412648Abstract: A component mounting device is capable of mounting a component having a feature portion on an upper surface, on a board. The component mounting device picks up a component by a pickup member and loads the picked-up component on a temporary loading stand at an angle substantially equal to a target mounting angle to the board. Subsequently, the component mounting device images the upper surface of the loaded component by an upper imaging device and picks up again the loaded component. Then, the component mounting device mounts the component picked up again at the target mounting angle at the target mounting position corrected based on the positional deviation amount of the feature portion recognized by the upper surface image of the imaged upper surface.Type: GrantFiled: March 23, 2018Date of Patent: August 9, 2022Assignee: FUJI CORPORATIONInventors: Hidenori Goto, Ryohei Kamio, Kota Niwa, Kohei Sugihara

Patent number: 10798861Abstract: A mounter capable of curtailing interference between a mounting head that has a component holding section, and an exchange-use component holding section and a storage section that holds the exchange-use component holding section. A controller of the mounter reads head identification information for identifying the mounting head from the mounting head. Also, different quantities of protruding sections are formed on nozzle tray in accordance with the height in the Z-axis direction. Also, pressure switches that are pressed by protruding sections so as to turn on and off are provided on loading plate on which nozzle tray is loaded. By this, the controller is able to determine whether interference will occur between the mounting head and nozzle tray based on the detection signal of the pressure switches before the mounting head is moved.Type: GrantFiled: November 6, 2015Date of Patent: October 6, 2020Assignee: FUJI CORPORATIONInventors: Koji Kawaguchi, Kohei Sugihara, Yoji Fujita

Patent number: 10784129Abstract: A mounting device in which a loading distance separating adjacent characteristic components are lined up side by side is shorter than separation distance between suction nozzle and mark camera, processing to image characteristic component by mark camera and recognize the position of characteristic component is performed consecutively or in one batch. With the mounting device, because mounting head is moved a loading distance that is shorter than the separation distance between suction nozzle and mark camera and image processing is performed consecutively or in one batch, the movement distance of mounting head is shorter.Type: GrantFiled: March 23, 2015Date of Patent: September 22, 2020Assignee: FUJI CORPORATIONInventors: Kohei Sugihara, Hidenori Goto

Patent number: 10746618Abstract: A load measuring device is provided with load sensor, data logger, and measurement start switch on body. When switch section is pressed down by a suction nozzle, load sensor outputs detection voltage to data logger in accordance with the size of the pressing load. Data logger records detection voltage for a specified time only from the time it starts receiving high level start recording signal from measurement start switch. By this, data logger does not record detection voltage until high level start recording signal is received from measurement start switch, thus does not incorrectly record vibrations and the like during conveyance as the load.Type: GrantFiled: November 4, 2015Date of Patent: August 18, 2020Assignee: FUJI CORPORATIONInventors: Koji Kawaguchi, Kohei Sugihara, Junichi Narita
