Abstract
An ultrasonic welding assembly is disclosed. The assembly includes a vibratory horn and at least one mount securing the horn. The horn has a resonant frequency and the mount has a resonant frequency about the same as the horn. The mount includes an inner portion that holds the horn at a nodal region. The mount also includes an outer surface that is coupled to a support member, for example, a bearing. The mount vibrates in resonance with the horn at the resonant frequency, wherein the vibration amplitude of the outer surface of the mount is generally up to about 15 percent of the vibration amplitude of the inner portion.

A system for ultrasonic manufacturing, comprising:
- a horn having a resonance at a predetermined frequency, and
- a mount having a resonance at about said predetermined frequency, wherein the mount is coupled to the horn at a point where the horn has a node at said predetermined frequency.
A mount for ultrasonic horn, comprising:
- a base element;
- a pair of flanges extending outwardly from the base element and defining an exterior bearing surface;
- and
- a mount element extending inwardly from the base element and defining an interior bearing surface,
- wherein the exterior bearing surface is a node when the interior bearing surface is driven at a predetermined frequency.
A method of mounting an ultrasonic horn, comprising:
- providing a horn having a resonance at a predetermined frequency, and
- attaching a mount having a resonance at about said predetermined frequency to the horn at a point where the horn has a node at the predetermined frequency.
