<p>This component-mounting machine is equipped with: a substrate transport device; a component supply device; a component transfer device; and an imaging/monitoring device, which has an imaging unit that obtains image data by capturing an image when a suction nozzle has picked up a component, a storage unit that saves the image data, and a determination unit that determines the state of the suction nozzle with respect to the picking up of a component and determines component defects on the basis of the image data. When an event that causes a change in the operating state of the component supply device or the component transfer device occurs (Yes in S41), the imaging/monitoring device saves the image data for a prescribed period of time before and after the causal event, or a prescribed quantity of image data, as the image data to be saved in the storage unit (S44), and deletes image data other than the image data to be saved after this other data has been used by the determination unit to make a determination (No in S41). Thus, only the image data before and after the occurrence of an event that causes a change in the operating state of the component supply device or the component transfer device is selected and saved for a long period of time, which enables efficient clarification of the event and efficient diagnosis of the cause when a defective substrate occurs or an equipment error occurs.</p> |
