PROBLEM TO BE SOLVED: To provide a component supply device and a component position recognition method which can easily, reliably and accurately detect a circumferential position of a wafer and accurately recognize a position of a wafer cut component.SOLUTION: A component supply device 20 has: a wafer illumination device 80 which is mounted on a second movement device 71 of a component push-up device 70 and irradiates a wafer U transferred to a component supply position A with light in a wide angle from below; and a camera 39 which is attached to a first movement device 31 of a component mounting device 30 and takes an image of a part of a circumference of the wafer U. Therefore a circuit and the like formed on a surface of the wafer U are not taken in the image and the wafer U is reflected as a shadow. Thereby the circumferential position of the wafer U can easily, reliably and accurately be detected and a position of a wafer cut component P can accurately be recognized. Consequently, the component supply device 20 can be reduced at cost and in size because a conventional optical sensor is unnecessary. |
