Patent ID: 7003872

Claim:
An electronic component mounting apparatus in which a second component feeder that supplies a second electronic component from a tray where the second electronic component is loaded is arranged at a section set between a mounting zone where a board mounting at least a first electronic component is disposed and a first component feeder that supplies the first electronic component, said electronic component mounting apparatus comprising: a mounting head configured to have a component holders that move up and down with holding the first and second electronic components, to be movable in mutually orthogonal X and Y-directions, and to hold at least the first electronic component from the first component feeder and mount the first electronic component on the board; a second electronic component mover configured to be installed in the second component feeder, and to retreat the second electronic component when at least either of the first electronic component held by the mounting head from the first component feeder and the component holder interferes with the second electronic component of the second component feeder because of movement of the mounting head; and a controller configured to perform operation control for the first component feeder, the second component feeder, the second electronic component mover and the mounting head, to have a memory part that stores height information of the first electronic component and the second electronic component, to determine presence or absence of the interference on a basis of the height information of the first electronic component held by the mounting head and the height information of the second electronic component at the second component feeder, and to perform retreat control to the second electronic component mover when the interference arises.
