Patent ID: 7290327

Claim:
A component mounting apparatus comprising: a component supply section for supplying components; a mounting head section for picking up a component from the component supply section and mounting the component onto a circuit substrate, said mounting head section including an x-y robot and a mounting head positioned by the x-y robot; and a controller for controlling the component supply section and the mounting head, the controller including: a pause detection section for detecting a pause of a component mounting operation during which the mounting section head need not be operated to mount components; an idling determination section for determining whether an idling operation is required based on detection of the pause; and an idling section for controlling the apparatus so as to perform an idling operation during the pause of the component mounting operation to prevent a fall of a temperature of the component mounting apparatus during the pause of the component mounting operation such as to reduce degradation of a component mounting accuracy due to temperature changes, said idling operation being performed in response to a determination by the idling determination section that the idling operation is required, and said idling operation including driving the x-y robot to move without effecting mounting of a component.
