Abstract
Ultrasonic welding device having a sonotrode (28) and an anvil (26), in which a flat part and at least one joining part are arranged between the sonotrode (28) and the anvil (26) during ultrasonic welding, and wherein a fastening element is held in a positively locking manner between the flat part and the joining part, and a damping element (22) that presses on the fastening element (8a) is provided, which is pressed on the fastening element in such a way that a relative movement between the fastening element and the flat part and/or the joining part is restricted during ultrasonic welding

1-23. (canceled)
A method of ultrasound welding comprising:
- captively arranging a fastening element on a flat part;
- arranging a damping element on the fastening element so that the fastening element is pressed against the flat part by means of the damping element;
- and
- applying ultrasonic oscillations to the flat part to form a weld, wherein a relative movement between the fastening element and the flat part during the ultrasonic welding is restricted.
An ultrasonic welding device comprising:
- an anvil having a surface;
- a sonotrode arranged for movement up and down perpendicular to the surface of the anvil;
- and
- at least one damping element that can be pressed on a fastening element captively arranged on a flat part to be welded by the sonotrode, wherein pressing the at least one damping element restricts relative movement between the fastening element and the flat part to be welded.
An ultrasonic welding system comprising:
- an anvil having a surface;
- a sonotrode arranged for movement up and down perpendicular to the surface of the anvil;
- a flat part placed over the surface of the anvil for welding by the sonotrode;
- a fastening element arranged on the flat part;
- and
- a damping element that can be pressed on the fastening element, wherein pressing the damping element restricts relative movement between the fastening element and the flat part.
