Abstract

The invention relates to a sonotrode assembly (3) for an ultrasonic welding device, having an elongated sonotrode (5) which extends in the z-direction and a zero bearing (7). The sonotrode has a sonotrode head (15) at the distal region, and the sonotrode (3) is configured so as to transmit ultrasonic vibrations introduced at the proximal region (9) to the sonotrode head such that the sonotrode minimally vibrates at a zero position (29) between the distal end and the proximal end in the z-direction. The zero bearing is arranged at the zero position and has a bearing element (45) and a pressing element (47). The bearing element has a first stop surface (41) which extends horizontally and a second stop surface (43) which extends vertically. The pressing element has a pressing body (57) and a fixing body (59) which can be releasably fixed to the pressing body. The fixing body is configured so as to be fixed to the pressing body by exerting a fixing force at least to be produced at a specified fixing position, and the pressing element is configured such that a self-supporting fixing body end (73) of the fixing body exerts a pressing force onto the sonotrode at the zero position thereof in a preferably diagonal direction transversely to the first and/or second stop surface when the fixing body is fixed to the pressing body in the specified fixing position. The fixing body is elastically connected to the bearing element via the pressing body such that the pressing force exerted by the fixing body end is determined predominantly by material properties and geometric properties of the pressing element and secondarily by the fixing force with which the fixing body is fixed to the pressing body in any case.

Abstract

A quality control method for ultrasound welding. The method provides for the generation of a tolerance range which is adjusted to the progress of the welding process and which is generated from measured values which influence the welding process. A measured value tolerance range is determined from measured values of executed welding processes, the measured values being associated with at least one parameter which influences the welding process and/or represents the goods of the welding process. Measured values are associated with an identical parameter of a further welding process following thereafter and are considered during the quality monitoring in such a way that the measured value tolerance range is changed in its form or composition to an average value for further welding processes, in accordance with the variance between the additional measured values and the tolerance range determined from previous measured values.
