Patent ID: 6910262

Claim:
An electric-component handling device comprising: a suction nozzle including (a) a nozzle body, and (b) a suction pipe extending from said nozzle body; a fiducial mark disposed at a predetermined position relative to said suction pipe; an image-taking device operable to take an image of an electric component held by suction by said suction pipe, and an image of said fiducial mark, in a longitudinal direction of said suction pipe; a relative-movement device operable to move said image-taking device and said suction nozzle relative to each other, in at least a direction intersecting said longitudinal direction of said suction pipe, so as to pass a relative position therebetween at which said electric component held by said suction pipe and said fiducial mark are concurrently located within a field of vision of said image-taking device; and an image data processing device operable to process said images of said electric component and said fiducial mark taken by said image-taking device, for obtaining a relative position between said fiducial mark and said electric component, and to obtain a position of said electric component relative to a nominal position of said suction pipe, on the basis of the obtained relative position between said fiducial mark and said electric component, and a known relative position between said fiducial mark and said nominal position of said suction pipe.
