Title:
ROBOTIC HAND TOOL SHARPENING AND CLEANING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/140220
Kind Code:
A1
Abstract:
An automated hand tool sharpening and cleaning system for sharpening the two opposed cutting edges of a blade is provided by the invention. The apparatus comprises a six-axis robotic arm, a pneumatic gripper, a vision sensor camera, a robotic controller, and rotating wheel assemblies used to grind, sharpen, and buff or polish the cutting edges of the knife blade. The blade cutting edges are profiled by the camera image that is processed by associated software to determine the blade profile by defining multiple points along the blade edge. The resulting profile data is then translated into a set of machine control commands fed to the robotic arm and pneumatic gripper via the robot controller for manipulating the knife blade edges via the robotic arm with respect to each of the grinding, coarse sharpening, fine sharpening, and buffing/polishing wheels and an associated wash station for remove bits of metal and other residue resulting from the sharpened knife blade.
