Abstract
An ultrasonic welding system is provided. The ultrasonic welding system includes a support structure for supporting a workpiece. The ultrasonic welding system also includes a weld head assembly including an ultrasonic converter carrying a sonotrode. The weld head assembly is moveable along a plurality of substantially horizontal axes. The sonotrode is configured to operate during a welding operation at a bond force of between 5-500 kg, and with a sonotrode tip motion amplitude of between 5-150 microns.
Claims22
An ultrasonic welding system comprising:
- a support structure for supporting a workpiece;
- and
- a weld head assembly including an ultrasonic converter carrying a sonotrode, the weld head assembly being moveable along a plurality of substantially horizontal axes, the sonotrode being configured to operate during a welding operation at a bond force of between 5-500 kg, and with a sonotrode tip motion amplitude of between 5-150 microns.
An ultrasonic welding system comprising:
- a support structure for supporting a workpiece;
- and
- a weld head assembly including an ultrasonic converter carrying a sonotrode, the weld head assembly being moveable along a plurality of substantially horizontal axes, the workpiece being provided to the ultrasonic welding system including a contact element and a base structure, wherein the sonotrode is configured to ultrasonically weld at least one conductive contact of the contact element to a respective conductive region of the base structure.
A method of operating an ultrasonic welding system, the method comprising the steps of:
- supporting a workpiece on a support structure of the ultrasonic welding system;
- and
- welding (i) a conductive contact of a contact element of the workpiece to (ii) a respective conductive region of a base structure of the workpiece, using a weld head assembly including an ultrasonic converter carrying a sonotrode, the weld head assembly being moveable along a plurality of substantially horizontal axes.
