Component mounting device and component mounting method

A component mounting method that is performed by a component mounting device that comprises a board positioning part that positions a board, a component supply part that includes a plurality of feeders which supply components to component supply positions, an mounting head that picks up and mounts the components supplied by the feeders on the board which is positioned by the board positioning part, and a component detecting unit that is provided in each of the feeders and detects whether the component is supplied to the component supply position of the feeder, and mounts the components on the board by controlling operations of the mounting head based on a mounting program in which a procedure of mounting turns that are the operations of the mounting head from picking up the component to mounting the component on the board, and identifiers of the feeders which are supply sources of the components for the mounting turns are recorded, comprising the steps of:

• reading out a mounting turn that is going to be performed from now on and the identifiers of the feeders that are the supply sources of the components for the mounting turn from the mounting program,
• determining, when the step of reading out a mounting turn is performed, whether there is a feeder which does not supply the component to the component supply position in the feeders corresponding to the identifiers that are read out, based on the output from the component detecting unit provided in the feeders corresponding to the identifiers that are read out,
• performing the mounting turn that is read out when there is not a feeder which does not supply the component to the component supply position in the feeders corresponding to the identifiers that are read out as a result of the above determining, and
• suspending the performing of the mounting turn that is read out, and reading out another mounting turn when there is a feeder which does not supply the component to the component supply position in the feeders corresponding to the identifiers that are read out as a result of the above determining.
