  • Publication number: 20230406649
    Abstract: A workpiece conveyance device includes: a plurality of holding heads that include a holding part and a vacuum pump; and a conveyance track. The vacuum pump includes a pump unit and a shaft part that is rotated to activate the pump unit. The shaft part includes a first magnet. The conveyance track includes a second magnet extending in a conveyance direction of the holding head and being arranged to generate a magnetic force between the second magnet and the first magnet.
