Component mounting machine

A component mounting machine that holds and mounts a component on a board, the machine comprising:

• a head having a suction nozzle configured to hold the component;
• a camera configured to image the component when the component is held in the suction nozzle;
• and
• a control device including a processor configured to:
• control the head to pick up the component with the suction nozzle,
• obtain an image of the component held in the suction nozzle using the camera,
• perform a pre-mounting inspection for inspecting a state of the component held in the suction nozzle based on the image of the component,
• when a determination of abnormality is made in the pre-mounting inspection,
• control the head to discard the component held in the suction nozzle in a discard box, and
• set a flag indicating that a post-mounting inspection is required when abnormality is determined,
• when a determination of normality is made in the pre-mounting inspection,
• determine whether there is a suspicion of abnormality based on at least one of a time taken to perform the pre-mounting inspection and a change in an amount of positional deviation of the component held in the suction nozzle compared to a positional deviation of a previously held component,
• set the flag indicating that the post-mounting inspection is required when there is a suspicion of abnormality, and
• control the head so that the component held in the suction nozzle is mounted on the board, and
• perform the post-mounting inspection for inspecting a state of a mounted component on the board by the head when the flag is set indicating that the post-mounting inspection is required.
