Claim of US Patent No. 10,462,947

1. A component mounting machine comprising:a board fixing device which fixes a printed circuit board;
a component supply device which supplies a component at a plurality of supply positions;
a component mounting head which includes (a) a rotating body which is rotatable around a rotation shaft line, (b) a plurality of component holding tools which are installed at an equivalent angle pitch on one circumference around the rotation shaft line, and which respectively hold a component, in the rotating body, and (c) a rotating body rotating device which rotates the rotating body which rotates the plurality of component holding tools along the circumference around the rotation shaft line;
a first component holding tool operating device which operates one component holding tool which is positioned at a first position set on the circumference among the plurality of component holding tools for holding and disengaging the component, and a second component holding tool operating device which operates one component holding tool which is positioned at a second position set on the circumference among the plurality of component holding tools for holding and disengaging the component; and
a head moving device which moves the component mounting head for receiving the component by the plurality of component holding tools from the component supply device, and for mounting the component held by the plurality of component holding tools onto the printed circuit board fixed by the board fixing device,
wherein the component supplied by the component supply device is mounted on the printed circuit board fixed by the board fixing device,
wherein the first position and the second position are set so that the second position is positioned in the middle of any two adjacent component holding tools among the plurality of component holding tools when one of the plurality of component holding tools is positioned at the first position, and
wherein, while the rotating body rotating device rotates the rotating body by a half of the alignment pitch angle of the plurality of component holding tools, the first component holding tool operating device and the second component holding tool operating device alternately operate the component holding tool which is positioned at the first position among the plurality of component holding tools, and the component holding tool which is at the second position among the plurality of component holding tools.
