An apparatus and method for ultrasonically welding wires includes an ultrasonic horn tip and associated structure for allowing adjustment to accommodate different diameters of wires to be welded while maintaining a tight grip around the wires during the welding process to avoid spreading or splaying of the wires. The tip is rotable to provide several alternative and interchangeable work surfaces on a standard-shaped readily machineable cross section, thereby allowing for a longer total worklife and a reduced cost of manufacture.

Apparatus and method for ultrasonic welding of wires

The invention relates to an apparatus and method for ultrasonically welding a conductor wire to an electrical terminal. The terminal has a channel portion for receiving the conductor wire. The electrical terminal with the wire therein is confined adjacent the welding tip whereby movement of the welding tip into the channel portion presses the conductor wire against the electrical terminal and welds it thereto.

Ultrasonically welding a conductor wire to an electrical terminal

Apparatus is provided for ultrasonic welding of wires which include a welding tip of a standard shaped readily machineable cross section with no concave surfaces. The welding tip is rotatable about an ultrasonic horn to present several alternative available worksurfaces. The worksurface in use defines a wall of the compression chamber into which wires to be welded are inserted. An anvil, a support, and a gathering tool each define an additional surface of the compression chamber. The position of each of these elements is adjustable thereby allowing for adjustment in two dimensions of the cross section of the compression chamber. This allows for the welding of various sizes or numbers of wires.

Apparatus for ultrasonic welding of wires

Apparatus for the ultrasonic sealing of plastic or metal containers which include a source of ultrasonic wave energy, an ultrasonic welding horn and an anvil. The ultrasonic welding horn is provided with means to adjust and make uniform the amplitude of vibration of the wave energy transmitted by the horn. This is accomplished by attaching weights of varying magnitude to the horn, thus assuring a uniform amplitude of the ultrasonic vibration across the face of the worksurface of the horn, to effect a uniform bond on a workpiece.
