ABSTRACT:
This invention relates to suction pick-up apparatus of an electrical or electronic component placement machine. A pick-up head 16 has a body 82 with a pick-up surface 84 and a piston 94 with a smaller pick-up surface 98 slidable in the body 82. The piston 94 is movable between an operative position projecting beyond the surface 84 and an inoperative position retracted into the body 82 by air under pressure directed to move the piston 94. The head 16 is constructed so that suction can be applied to an appropriate one of the surfaces 84, 98 to retain a component engaged by that surface on the surface. The apparatus may have several pick-up heads 16 mounted at equal intervals about the axis of a carousel 14 for stepwise movement through a plurality of stations 26, 42-58 where various operations are carried out. Where the apparatus comprises a plurality of heads 16 mounted on a carrier 34 an appropriate head may be selected by a bowden cable mechanism 68.
