An ultrasonic welding device includes a sonotrode with a sonotrode surface, a lateral slide with a lateral slide surface, a touching element with a touching surface and an insertion chamber for inserting joining parts. The insertion chamber is defined in a first axial direction (y) on a first side by the sonotrode surface and in a second axial direction (x) on a second side by the lateral slide surface and on a third side opposing the second side by the touching surface. Furthermore, the ultrasonic welding device includes a first receiving element with a first stop edge and a second receiving element with a second stop edge. The first receiving element and the second receiving element are arranged to be movable in relation to each other between a starting position and an end position.

Ultrasonic welding device with a v-shaped joining part receptacle

An ultrasonic welding device includes a sonotrode, an anvil, a touching element, a lateral slide, a stop element and a receiving chamber in which joining partners are received and which is defined by bordering components of the ultrasonic welding device. The receiving chamber is defined on a first side by the sonotrode and on a second side by the anvil. The receiving chamber is further defined on a third side by the touching element and on a fourth side by the lateral slide. The receiving chamber is further defined on a fifth side, extending transverse to the first to fourth sides, by the stop element. The first stop element is electrically conductive on its surface directed toward the receiving chamber in order to form a first electrode.

Ultrasonic welding device with position detection of joint partners

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.

Ultrasonic welding device with displaceable stop element

The invention relates to a device and to a method for producing a tested weld joint between two contact elements (), which are joined together in a welding plane S, comprising a compressing space for accommodating the contact elements (), said compressing space being delimited by a work surface of a sonotrode, which transmits ultrasonic oscillations, and a counter-surface () of a counter-electrode () in a first axial direction at two opposing sides and by delimiting surfaces of opposing delimiting elements in a second axial direction at two opposing sides, said device comprising a test head () next to the compressing space, and said test head being able to be transferred from a position outside of the compressing space to a position within the compressing space in such a manner that the test head () is disposed within the open compressing space in a test mode of the device for subjecting a contact element () of the previously produced weld joint to a shear force essentially oriented parallel to the welding plane S, and said test head () being disposed outside of the compressing space in a welding mode of the device for producing the weld joint.
