Patents by Inventor Upul Palliyaguru

Upul Palliyaguru has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12318916
    Abstract: A robot end effector for surface preparation in an automated inspection and repair system for composite parts has an end effector body and a plasma control unit and a plasma jet nozzle supported on the end effector body. The plasma control unit directs a jet of atmospheric plasma through the plasma jet nozzle. A slave tool changer is secured to the end effector body. The slave tool changer releasably and operatively connects the robot end effector to an industrial robot such that the industrial robot can move the robot end effector along a composite part as the plasma control unit directs a jet of atmospheric plasma through the plasma jet nozzle toward the composite part to clean the composite part and increase a surface free energy of the composite part.

  • Publication number: 20230131624
    Abstract: A surface analyst end effector for an automated inspection and repair system for composite parts. A surface analyst system and a tool changer are supported on a chassis. A control unit of the surface analyst system is configured to conduct a bond readiness test by which the control unit directs an inspection head to place a drop of liquid onto a surface of a composite part and directs the inspection head to capture an image of the drop on the surface. The slave tool changer releasably and operatively connects the end effector to an industrial robot such that the industrial robot can move the end effector along the composite part and the inspection and repair system can signal the surface analyst to conduct a bond readiness test. The surface analyst end effector is interchangeable with other end effectors of the inspection and repair system for performing inspection and repair methods.
