Abstract
A feeder mechanism for a pick-and-place machine with an adjustable shutter mechanism is disclosed. The components are contained within pockets formed in a reeled tape. The shutter mechanism includes a pair of spring blades that cover the pocket, but are spread apart by the vacuum tip when the spindle is lowered. In this way, the shutter can maintain the component in the proper position for pick-up while allowing the vacuum spindle to access the component, which, in turn, maintains proper attitude of component while the blades are retracted.
