Apparatus for and method of correcting component holding position

Abstract

An electronic component mounting apparatus uses sensors and a controller to correct the position at which a component holder, generally a suction nozzle, captures a component, thus avoiding component capture errors and failures. More specifically, sensors detect a deviation amount between a predetermined location on a component absorbed by a suction nozzle and the suction position of the suction nozzle. The deviation amount is multiplied by a sensitivity coefficient, and the resulting adjusted deviation amount is then applied by the controller to correct the position of the suction nozzle when capturing a subsequent component. Accordingly, the subsequent component is absorbed by the suction nozzle normal to the component and at a position substantially centered with respect to the component, reducing the occurrence of suction errors.
