Ultrasonic welding device including adjustable stop-element

Abstract

The invention relates to an ultrasonic welding device (1) which comprises a sonotrode (3), an anvil (5), a touching element (7), a lateral slide (9), a first stop element (11), a drive device (29) and a receiving space (13) in which joining partners (15) are to be received. The receiving space is delimited on a first side by a surface (21) of the sonotrode and on a second side, which is opposite the first side, by a surface (23) of the anvil. The receiving space is also delimited on a third side by a surface (25) of the touching element and on a fourth side, which is opposite the third side, by a surface (27) of the lateral slide. The first stop element is movable between a retracted position and an extended position. In the retracted position, the first stop element delimits the receiving space on a fifth side which extends transversely to the first to fourth sides, and in the extended position, the first stop element leaves the receiving space open on the fifth side. The drive device is designed to move the first stop element actively between the retracted position and the extended position. (Figure 1)
