Smart Welder SW1085 – with rotational weldhead

Best of both Technologies: ultrasonic welding & wire bonding

Hesse Mechatronics Smart Welder combine the best of two technologies:

  • The force and ultrasonic power of ultrasonic welding equipment
    and
  • The flexibility, precision, speed and advanced process control features of wire bonding machines.

Smart Welding is the leading-edge technology in producing ultrasonically welded connections. This is due to increased process control, driving the limits of connecting different material combinations (e.g. for applications like power electronics and battery packs).

Smart Welders by Hesse, can precisely position a sonotrode to a product. An image recognition system determines the exact weld location very quickly and accurately, based on a derivation of an optimal trajectory. Together with long and narrow sonotrodes, this allows small pitching and compact products/higher power density.
Further advanced functions include touchdown sensing, precise and dynamic contact force control, diverse process control features such as monitoring of ultrasonic characteristics and deformation (ref. DVS 2811), and standardized interfaces for assembly line integration.

Smart Welders can, like ultrasonic wire bonders, flexibly handle a large variety of products. New products only require a program change and possibly adapted clamping and automation.
