Component mounting device

A component mounting device, comprising:

• a component transfer device configured to hold a component and mount the component on a conveyed board, the component being one of a plurality of components mounted on the conveyed board,
• an imaging device configured to image the component or the board, and
• a control device configured to control the component transfer device, the control device including:
• a model data storage section configured to store model data produced based on information about each of the plurality of components, the model data includes image data indicating an outer shape of a component of the plurality of components;
• an error determining section configured to determine whether a processing error has occurred in a series of processes from the start of the holding operation of the component to the completion of mounting, wherein the processing error is at least one of a component pickup error, a component dropped error or a component matching error, and wherein the component matching error is detected by comparing the model data with the image data of the component when picked up and held by a suction nozzle, and wherein the component pickup error and the component dropped error are detected by a change in a negative pressure or a flow rate of the suction nozzle, and
• a confirmation-necessity storage section configured to store information about whether confirmation of validity of the model data is necessary for each component of the plurality of components when a processing error has occurred in the series of processes performed based on each piece of model data stored in the model data storage section, wherein,
• when the control device determines that the processing error has occurred and the component held by the component transfer device during the processing error is registered in the confirmation-necessary storage section as a component that confirmation of validity of the model data is necessary, the control device temporarily suspends the mounting operation by the component transfer device and indicates on a display that validity of the component is necessary, and
• when the control device determines that the processing error has occurred and the component held by the component transfer device during the processing error is registered in the confirmation-necessary storage section as a component that confirmation of validity of the model data is not necessary, the control device continues the mounting operation by the component transfer device.
