Title: METHOD AND DEVICE FOR ULTRASONICALLY CONNECTING PARTS TO BE JOINED
Abstract:
The invention relates to a method for ultrasonically connecting, in particular ultrasonically welding and/or ultrasonically soldering, parts to be joined (20, 21), in particular electrical conductors (20, 21), comprising the steps of a) in a time period from a first point in time (t1) to a second point in time (t2): subjecting at least one of the parts to be joined (20, 21) to ultrasound by means of a sonotrode (11) that is in contact with the part to be joined (20, 21) in such a way that the parts to be joined (20, 21) are connected; b) separating the sonotrode (11) from the parts to be joined (20, 21), wherein the sonotrode (11) ends contact with the part to be joined (20, 21) at a third point in time (t3). At least in a time period from the first point in time (t1) to the third point in time (t3), ultrasound is continuously introduced into the sonotrode (11). The invention also relates to a device (10) for ultrasonically connecting parts to be joined (20, 21), in particular electrical conductors (20, 21), and to a method for retrofitting an existing device for ultrasonically connecting parts to be joined (20, 21), in particular electrical conductors (20, 21).
