Where particular flexibility is required in ultrasonic processing, either due to the complex shape of a part or the need to process a range of different parts or products, then Swiss ultrasonics specialist Telsonic suggests mounting the ultrasonic modules on a six-axis robot system.
This concept has been adopted by several sectors including automotive and medical devices, says the company, where the capability to reposition and reorient the processing head has eliminated the need for complex and expensive bespoke solutions with long lead times.
Telsonic cites several benefits from taking the process to the part, not least that the robot program can be modified as required to take account of new part types or changes to part design. The configuration is appropriate to large and/or complex 3D components such as moulded plastic automotive parts manufactured in the industry. The robot, using a single-point system such as Telsonic’s compact 35 or 20Khz ultrasonic drivelines, can be used for cutting, welding or other forms of joining – for instance bonding sound insulating material to a substrate.
Robot-mounted ultrasonics is used on components including door panels, under-bonnet components, interior panels, engine covers and roof liners.
