Abstract: A method and apparatus for joining multiple layers of materials using an ultrasonic welding apparatus. The ultrasonic welding apparatus utilizes a sonotrode to perform a weld between at least the top and intermediate layer of the multi-layer member. Then, either the multi-layer member or the ultrasonic welding apparatus is rotated such that the bottom layer is positioned adjacent the sonotrode wherein the sonotrode forms a weld between at least the bottom layer and intermediate layer of the multi-layer member. The apparatus includes an ultrasonic welding gun having a C-shape frame including a base portion and a head portion. An ultrasonic welding device, including a sonotrode, is secured to the head portion and an anvil secured to the base portion. The ultrasonic welding gun is connected to a robot operative to position the ultrasonic welding gun to perform the welding operation.

Abstract: An apparatus and method for ultrasonically welding workpieces that reduces sonotrode adhesion during the ultrasonic welding process. The sonotrode includes a contact surface wherein a fluid is deposited on the contact surface prior to the welding process. The fluid may be applied in different ways, including providing an aperture in the contact surface of the sonotrode. In addition, the sonotrode may be cooled below the dew point of the surrounding atmosphere thus causing moisture to form on the contact surface of the sonotrode. Cooling the sonotrode to a temperature above the dew point also reduces sonotrode adhesion during the ultrasonic welding process.

Abstract: An apparatus for ultrasonically welding workpieces that reduces sonotrode adhesion during the ultrasonic welding process. The sonotrode tip has a specific surface configuration, including a curvilinear shaped outer surface combined with a plurality of grooves and lands. Due to the curvilinear surface, the depth of the grooves gradually decreases near the outer edge or periphery of a contact surface of the sonotrode tip. Further, such a groove and land combination also provides a sharp edge or corner that reduces sliding of the tip on the workpiece and correspondingly reduces sticking. In addition, various types of coatings or inserts may also be used to reduce sticking of the sonotrode tip to the workpiece.
