Abstract:
An actuating drive for a pneumatic valve of a revolver-type movable insertion head for placement of electrical components onto a components carrier wherein the insertion head includes a stator and a rotor mounted thereat which can be actuated in an indexed fashion and which is provided with a plurality of circularly protruding suction pipettes which can be successively rotated into a placement attitude for the components, wherein a displaceable valve is allocated to each of the suction pipettes for changing the pressure relations in the suction pipette, wherein the actuating drive is anchored at the stator which becomes engaged in the placement attitude with displaceable operating elements of the valve where the elements are each provided with at least one run-in bevel, the actuating drive comprising a freely projecting flex transducer having a piezoelectric leaf spring securely anchored at a first end to the stator and which projects at a second end into an engagement region of the operating elements, the piezoelectric leaf spring positioned substantially perpendicular to an actuation direction of the valve.
