ABSTRACT:
An ultrasonic welding assembly, comprising: a sonotrode having a single welding region and two nodal regions formed on either side of the welding region; a mounting plate for supporting the sonotrode having a force application region on the upper surface thereof; at least one ultrasonic transducer connected to the sonotrode; at least one diaphragm spring disposed between the ultrasonic transducer and the sonotrode; at least one roller bearing connected to the diaphragm spring; at least two linear guides connected to the roller bearing, wherein the at least two linear guides are connected to the mounting plate and support the roller bearing and the sonotrode in a flexible manner; and first and second low-friction linear bearings in contact with nodal regions for the application of downward force to the sonotrode, wherein the first and second linear bearings are connected to the mounting plate.
