<p>An electronic-part surface mounting apparatus includes an S-Z shaft vertically movable with respect to the mounted surface of a printed circuit board on which mounted parts such as electronic parts are mounted, and rotatable in a plane parallel to the mounted surface; an arm member revolving around the S-Z shaft; a plural number of Z-shafts, supported by the arm member, being vertically movable with respect to the mounted surface; cam unit revolving around the Z-shafts to cause the Z-shafts to individually move in a reciprocating manner; attraction/mounting unit operating such that at a position where the Z-shafts come nearest to the mounted surface, the attraction/mounting unit releases the mounted part from its seizure by the absorption nozzle attached to the lower end of the Z-shaft and mounts the mounted part on the mounted surface. With one cycle of the cam unit, a plural number of Z-shafts descend and ascend, so that the attracting and mounting work of the mounted part are successively carried out, thereby reducing their tact time. <MATH></p> |
