Abstract (en)

[origin: WO2022035924A1] An ultrasonic welder (10) has a booster (50) and stack assembly (34) carrying an ultrasonic horn (14). The stack assembly is self-leveling and rotational. Also, the ultrasonic horn is annular and is mounted against the booster, which has a threaded cavity, by a threaded bolt (52) that passes through the annular ultrasonic horn and into the threaded cavity of the booster. The horn includes a shaft portion (35) attachable to a source of high-frequency ultrasonic vibration, a transition (37) having a height and a width and being smaller in cross- sectional area than the shaft cross-sectional area by tapering its height. The transition is attached to an intermediate holder (31) and has a cross-sectional area that is smaller than the transition cross-sectional area. The intermediate holder has a concave width dimples. The intermediate holder carries a rectangular welding tip (33) having a cross-sectional area larger than the intermediate holder cross-sectional area.
