  • Publication number: 20240098958
    Abstract: 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.

  • Patent number: 11751370
    Abstract: A correction amount calculation device includes a first acquisition section and a correction amount calculation section. The first acquisition section is configured to acquire a first positional deviation amount, which is a positional deviation amount of a printing position detected by a printing inspection machine with respect to a pad position, and a second positional deviation amount, which is a positional deviation amount of a mounting position detected by a appearance inspection machine with respect to the pad position. The correction amount calculation section is configured to, based on the first positional deviation amount and the second positional deviation amount, calculate a correction amount, which is used in the mounting process of a board product to be produced later, regarding a third positional deviation amount, which is a positional deviation amount of the mounting position with respect to the printing position.

  • Publication number: 20220151120
    Abstract: A correction amount calculation device includes a selection section and a correction amount calculation section. The selection section is configured to select a target component in which a movement amount of the component on a board before and after being conveyed to a reflow furnace is equal to or less than a predetermined allowable value. The correction amount calculation section is configured to calculate a correction amount, which is used in a mounting process of a board product to be produced later, regarding a positional deviation amount of the mounting position of the target component selected by the selection section with respect to a target mounting position.
