COMPONENT MOUNTING DEVICE

PROBLEM TO BE SOLVED: To provide a component mounting device for reducing production man-hour of a substrate when components are mounted on different types of substrates which are combined by the prescribed number of substrates.SOLUTION: While a substrate is conveyed in/out to/from a first or a second component mounting position in either a first or second substrate conveyance device 10a or 10b, a controller 60 controls a component transfer device 40 to mount the component on the first or the second substrate Sa or Sb conveyed in the first or the second component mounting position by the other first or second substrate conveyance device 10a or 10b. Thus, conveying-in/out time of the first or the second substrate can effectively be used and the mounting of the component on the first or the second substrate is made efficient to improve production efficiency of the substrate. The controller 60 controls N-pieces of second substrates Sb to mount the components in the second component mounting position while M-pieces of first substrates Sa mount the components in the first component mounting position. Thus, occurrence of intermediate stock of the first substrates or the second substrates when M-pieces of first substrates and N-pieces of second substrates are required can be suppressed.
