Abstract

An ultrasonic welding device includes a sonotrode, an anvil, a touching element, a lateral slide, a first stop element, a drive device, and a receiving chamber in which joining partners are to be received. The receiving chamber is defined on a first side by a surface of the sonotrode and on a second side opposing the first side by a surface of the anvil. The receiving chamber is further defined on a third side by a surface of the touching element and on a fourth side opposing the third side by a surface of the lateral slide. The first stop element is displaceable between a pulled-in position and a pulled-out position. The first stop element in the pulled-in position defines the receiving chamber on a fifth side extending transverse to the first to fourth sides and in the pulled-out position leaves the receiving chamber open on the fifth side.
