Abstract
An ultrasonic welder includes a housing having an ultrasonic transducer, a horn mounted to one end of the housing, a motor having a shaft, and a mounting assembly having a fastener such as a threaded screw. One screw end is coupled to the motor shaft to rotate as the motor shaft is being driven. The other screw end extends into a threaded screw receiver running within the housing. Upon rotating in one direction, the screw engages more threads of the screw receiver such that the housing with the horn move upward. Upon rotating in the other direction, the screw engages less threads of the screw receiver such that the housing with the horn moves downward. A linear transducer extends from the mounting assembly into the housing to monitor the horn position. A pair of guide shafts extend from the mounting assembly into the housing to stabilize the horn positioning.
