Tomblin, J.S., Saathoff, C., & Palliyaguru, U., inventors; Wichita State University, assignee. Surface preparation end effector for industrial robot system and inspection and repair processes. United States patent US 12318916 B2. 2025, June 3.
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.
