Abstract
Apparatus for the automated feeding, placement and ultrasonic welding of a metal disc, such as a copper heatsink, to a recipient workpiece. A metal disc is automatically fed through the broader end of a chamfered bore cut in a weld location mask. The metal disc is gravity-fed to the narrower end of the bore as the weld location mask is automatically positioned over a recipient workpiece. An ultrasonic welding tip is inserted through the bore to hold the metal disc against the recipient workpiece. Welding of the disc to the recipient workpiece is accomplished by ultrasonically vibrating the tip.
