Abstract
A method and device for vacuum assist picking and placing a first component part relative to a second component part in preparation for ultrasonically welding the first component part to the second component part and ultrasonically welding the first component part to the second component part with the combination ultrasonic weld horn/vacuum pickup. A combination ultrasonic weld horn/vacuum pickup includes an ultrasonic weld horn including a vacuum conduit. A vacuum or negative pressure is directed through the vacuum conduit providing necessary suction at the tip of the weld horn to permit the weld horn to pick and hold a first component part during positioning of the part for welding to a second component part. In the preferred embodiment of the invention, the conduit is formed as a bore milled along a longitudinal axis of the weld horn.
