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 an ultrasonic welding device comprising a sonotrode () transmitting ultrasonic vibrations and an anvil () disposed on an anvil carrier (), the anvil () being disposed on the anvil carrier () in an exchangeable manner so that an mounting surface () of the anvil () rests against a support surface () of the anvil carrier () by means of a normal force exerted by a pretensioning device, the mounting surface () of the anvil () having a surface hardness greater than the surface hardness of the support surface () of the anvil carrier (), the mounting surface () having a surface structure at least in the area of a partial surface, and the mounting surface () having a surface roughness of R/R&#x2265;2 at least in the area of the partial surface.

Ultrasonic welding device

An ultrasonic welding device includes a sonotrode emitting longitudinal vibrations in the direction of a longitudinal sonotrode axis which comprises a work surface on a sonotrode head and an anvil. A weldment accommodation for a weld deposit is between the work surface 'p' and a counterface of the anvil. The ultrasonic welding device includes a stop device for defining the welding position with respect to the work surface. The counterface is disposed at an inclination &#x3b1; towards the longitudinal sonotrode axis such that when the counterface is inclined downward towards a vibration node adjacent to the work surface, distance a between the work surface and the counterface continuously increases towards the vibration node, and when the counterface is inclined upward towards a vibration node adjacent to the work surface distance a is essentially constant.

The invention relates to a device for welding rod-shaped conductors (), comprising a compression chamber for receiving joining sections () of the conductors to be joined together, the compression chamber being limited in a first axial direction (z-axis) on two opposite sides by an active surface of a sonotrode () transmitting ultrasonic vibrations in the direction of the z-axis and by a counter surface of a counter electrode (), the device having a knife device which is provided with a drive device and comprises a knife () movable in the direction of the z-axis, said knife having a cutting edge which can be moved past the compression chamber, wherein a drive motor of the drive device is arranged in an installation space arranged below the sonotrode, the drive motor being connected to a knife holder () via a deflection gear () in order for the knife to be able to perform a cutting motion, the knife being moveable in the direction of the z-axis.
