<p>A device (1 ) for picking and placing electronic components (C) for printed circuit boards comprises a shaft (2a) provided with an inner cavity that can be connected to an air sucking system, a nozzle (4) being arranged at the free end of the shaft, in which said nozzle (4) communicates with said inner cavity and is telescopically movable with respect a said shaft (2a) and in which, in an operation condition in which said air sucking system is operating, the nozzle (4) is subject to a sucking force (Fr) axially directed toward the shaft (2a). The device also comprises contrasting means (8, 9) suitable for generating a contrasting force (Fc) in the axial direction and opposite to said sucking force (Fr) in said operation condition.</p> |
