Component mounting machine and method for calculating correction value

A component mounting machine comprising:

• a nozzle configured to pick up a component;
• a head to which the nozzle is detachably attached, the head including a nozzle lifting and lowering mechanism configured to lift and lower the nozzle in a Z direction;
• an XY movement mechanism configured to move the head in an X direction and a Y direction;
• a board conveyance device configured to carry a board into a board mounting position and carry the board out from the board mounting position;
• and
• a control device configured to control the nozzle lifting and lowering mechanism, the XY movement mechanism, and the board conveyance device so that the component picked up by the nozzle is mounted on the board carried into the board mounting position, wherein
• the control device includes
• a component mounting position setting section configured to set, for each component to be mounted on the board, a component mounting position which is a position in the X direction and the Y direction at which the component is to be mounted,
• a component mounting height setting section configured to set, for each component to be mounted on the board, a component mounting height which is a position in the Z direction at which the component is to be mounted,
• a mounting position correction section configured to correct, for each component to be mounted on the board, the component mounting position of the component set by the component mounting position setting section with a first correction value that varies according to the component mounting height of the component set by the component mounting height setting section, and
• an XY movement mechanism drive section configured to drive the XY movement mechanism based on the component mounting position corrected by the mounting position correction section.
