1. An ultrasonic welding device, comprising:
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;
wherein 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;
wherein 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;
wherein the first stop element is displaceable between a pulled-in position and a pulled-out position;
wherein 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; and
wherein the drive device is configured to actively displace the first stop element between the pulled-in position and the pulled-out position.
