ABSTRACT:
An electronic parts automatic mounting apparatus is disclosed in which a plurality of suction nozzles are provided on the peripheral edge of an intermittently rotating turntable. Electronic parts are delivered to the turntable from a part supply portion, with the parts suctioned and held by the suction nozzles. The electronic parts are then transferred, positioned and mounted on a print substrate placed on an X-Y table. The apparatus is provided with part adjustment means for subjecting the electronic parts suctioned and held by the suction nozzle to various stepwise adjustments at a plurality of working stations provided during the part transfer. The part adjusting means comprise a plurality of positioning working units for positioning electronic parts arranged in correspondence to one part positioning station of the working units, each of the positioning working units being selectively actuated according to the size and shape of the electronic parts. Thus, the positioning of the electronic parts prior to mounting on the print substrate can be carried out with high accuracy, eliminating the necessity for replacing the apparatus according to the size and shape of the tipped parts.
