Component mounting machine and retry method for component collection

摘要

A component mounting machine comprising: a component supply device that supplies a component to a supply position; and a component transfer device that collects the component from the supply position using a component mounting tool and mounts the component on a substrate. Before or when collecting the component using a tool, a component detection unit that detects whether or not the component exists at the supply position, and whether the component mounting tool collects and holds the component. Whether or not to perform a retry operation of collecting the component again using the component mounting tool based on the holding detection unit that detects whether or not the detection result of the component detection unit and the detection result of the holding detection unit And a retry performing unit that performs the retry operation based on the determination result.
