Modification of robotic installation of ultrasonic welding for fixing soundproofing fabrics in wheel arches. The modification adds two new turning systems in order to increase capacity and integrate the new models.

Necesidad Planteada

Modification of robotic installation of ultrasonic welding for fixing soundproofing fabrics in wheel arches. The modification adds two new turning systems in order to increase capacity and integrate the new models.

Solución

ULTRASONIC WELDING: The claw, equipped with a sonotrode and two tips, is mounted on a tilting system that allows two points to be made simultaneously on the surface.
This system simplifies the adjustment in the robot's programming, improving the quality of the points while reducing cycle times.

TURNING TABLE
Modular structure that is integrated into the machine to be able to integrate the new wheel arch models.
It incorporates:
- UGI (180º Intermittent Turn Unit)
- Harting connection system.
- System of centering in current structure.
- Transport system with forklift or overhead crane.

WELDING TOOL
Tool CAM mechanized in resin and with the geometry of the wheel arch of each reference.

ULTRASOUND CLAW

The claw incorporates a sonotrode system with two tips and also:
- Tilt system.
- Guided cylinder with controlled pressure.
- Sonotrode tips cooling system.

Ventajas
Machine adaptation to new models while also maintaining backward compatibility with old models.
Improvement in Quality, thanks to the changes made in the tilting claw that absorb the differences of pieces, improving the quality of the welding points in each piece.
Reduction of non-conformities, by detecting each of the staples that are installed.
Productivity improvement, by integrating the turning tables that allow the operator to load and unload while the robot works.
