Abstract
In the modern production line, two parts, viz a plastic part and a threaded insert made of metal, are joined by ultrasound. A known ultrasonic unit comprising an ultrasonic generator (6), a converter (7), a booster (8) and a sonotrode (9) are used. In order to make an associated production particularly universal and to be able to perform the work quickly and precisely, the invention proposes to mount the ultrasonic unit (2) on a programmable arm (3) of a handling device (1), whereby the ultrasonic unit (2) is only operable in the working position of the arm (3) and, in this working position, a programmable process control unit (5), which controls the ultrasonic unit (2), is electrically connected to the control unit (4) of the handling device (1). No stationary backplate (16) for the workpieces is required if the ultrasonic unit (2) is equipped with a support arm (7) for a backplate (18) adjustable by the process control unit (5).
