  • Publication number: 20220386517
    Abstract: A component mounting device is configured to mount, on a substrate, an electronic component having a functional unit. The component mounting device includes a component supply mechanism, a recognition unit, a component mounting mechanism, and a holding position determination unit. The component supply mechanism supplies the electronic component. The recognition unit recognizes a position of the functional unit. The component mounting mechanism holds the electronic component supplied from the component supply mechanism and mounts the electronic component on the substrate. The holding position determination unit determines a holding position of the electronic component by the component mounting mechanism based on the position of the functional unit recognized by the recognition unit.

    Abstract: A method for manufacturing a mounting board includes a first outer shape position acquisition step, a feature portion position acquisition step, a calculation step, a holding step, a second outer shape position acquisition step, and a mounting step. In the first outer shape position acquisition step, a first outer shape position of a component is acquired. In the feature portion position acquisition step, a position of a feature portion is acquired. In the calculation step, a deviation amount of the position of the feature portion with respect to the first outer shape position is calculated. In the second outer shape position acquisition step, a second outer shape position of the component is acquired. In the mounting step, the feature portion of the component is mounted to be positioned on a target position of a board based on the second outer shape position and the deviation amount.
