Abstract
A component mounting apparatus includes a component holding and conveying device for holding and conveying a component and mounting the component onto a circuit board, a circuit board holding device for holding the circuit board, an image recognition optical system for performing recognition of the component and the circuit board with different fields of view, respectively, and a control section. The control section repeatedly determines an optical axis shift amount with the two fields of view between a position of the component and a position of the circuit board recognized by the image recognition optical system. Based on these determination results, the control section determines an optical axis shift amount for calibration, wherein calibration of the image recognition optical system is performed based on the optical-axis shift amount for calibration determined by the control section. Then, the component is mounted onto the circuit board.
