ABSTRACT:
A vacuum spindle for picking and placing components is operatively associated with a turret assembly which carries a supply of various component engaging tips for the spindle in corresponding holes or chambers of the turret. During picking and placing of the components, the spindle extends through the turret chamber from which the tip of the spindle was acquired. In order to exchange tips, the spindle is retracted to a first position at which the tip may be relocked in its chamber of the turret and then to a second position which is sufficient for the turret to be rotated for coaxial alignment of the spindle with another chamber and tip. Then, the replacement tip is acquired by extending the spindle into engagement with the tip and unlocking it from its chamber of the turret. Thus, various tips for the spindle may be interchanged after placement of a component and while the spindle is being repositioned in X and Y to the next pick-up site without the need to stop at an intermediate location.
