Abstract:
1. A component mounting apparatus comprising: a component feeding section for feeding components to a predetermined location; an object handling device for handling and positioning an object to which a component is to be mounted at a predetermined location, for component mounting, and for transferring the object to another place; a component handling device for picking up a component with a working face of a suction nozzle, bringing the component to a position where a metal interconnect of the component and a metal interconnect of the object face each other, and pressing the component onto the object while ultrasonic vibration is applied to the suction nozzle thereby ultrasonically bonding the component to the object; an ultrasonic vibration device for applying ultrasonic vibration between a support point of the suction nozzle, around which the suction nozzle is rockably supported, and the working face of the suction nozzle, the ultrasonic vibration device is configured to vibrate parallel to the working face of the suction nozzle; a polishing device for refinishing the working face of the suction nozzle at appropriate times in between bonding of a component to the object, to have a predetermined surface roughness by frictional contact between the working face and an abrasive; a controller for controlling the above devices to activate the polishing device and ultrasonic vibration device at appropriate times to bring the working face of the suction nozzle into contact with the abrasive and applying ultrasonic vibration to the suction nozzle to refinish the working face with the abrasive; and a slip detector for detecting slip between the working face of the suction nozzle and the component when ultrasonic bonding is performed, wherein the controller executes the polishing of the working face of the suction nozzle in accordance with detection results of the slip detector.
