Abstract:
1. A circuit board transferring apparatus comprising: a moving mechanism for vacuum-attracting the pad forming face of a circuit board and picking up the circuit board by an attracting nozzle and transferring the circuit board to a carrying tray on whose surface an adhesive layer is formed; an imaging unit for photographing the pad forming face of the circuit board picked up by the attracting nozzle; image processing means for processing the image photographed by the imaging unit and recognizing the arrangement of pads; and positioning means for deciding a transfer position of the circuit board on the carrying tray in accordance with a recognition result by the image processing means, wherein the attracting nozzle mounts and releases the circuit board in an upward facing position on a photographing table to image the pad forming face with the image processing means, and wherein, after the image processing means images the pad forming face, the attracting nozzle picks up the circuit board from the photographing table in a specified position by the positioning means and transfers the circuit board to a predetermined position on the carrying tray while maintaining the pad forming face in the upward facing position.
