Patent ID: 6967474

Claim:
A device ( 1 ) for positioning an electronic test head ( 2 ) with respect to a manipulator ( 3 ) for manipulating electronic components, including integrated circuits, comprising: a supporting structure ( 4 ) fitted to a base ( 5 ); a frame ( 6 ) to which the electronic head ( 2 ) is connectable; and an actuating assembly ( 7 ) for moving the frame ( 6 ) with respect to the supporting structure ( 4 ); retaining means ( 25 ) by which said base ( 5 ) cooperates with a supporting surface ( 26 ) and is movable in any direction parallel to said supporting surface ( 26 ); actuating means ( 28 ) are pneumatic actuating means, which release said shoes ( 27 ) from the supporting surface ( 26 ) by emitting a pressurized fluid; characterized in that said retaining means ( 25 ) secure the base ( 5 ) to the supporting surface ( 26 ) in a direction substantially perpendicular to the supporting surface ( 26 ), and permit rotation and translation of the base ( 5 ) in a plane parallel to the supporting surface ( 26 ); and characterized in that said retaining means ( 25 ) comprise a number of shoes ( 27 ) resting on the supporting surface ( 26 ) and associated with actuating means ( 28 ) for selectively locking the shoes ( 27 ) with respect to the supporting surface ( 26 ) and releasing the shoes ( 27 ) from the supporting surface ( 26 ).
