AI Technical Summary

Technical Problem

Existing robotic sharpening systems for cutting tools often manipulate tools by their handles, leading to issues like increased flex during sharpening, reduced gripping effectiveness due to blade width and surface substances, and obstruction of QR codes, which results in inaccurate and inefficient sharpening processes.

Method used

A robotic sharpening system that grips the blade of cutting tools at a distance away from the cutting edge, using a robotic arm with a gripper and 3D vision station to produce images of the blade, and processes each side of the cutting edge in succession at grinding and polishing stations, allowing for precise and consistent sharpening regardless of handle size or shape.

Benefits of technology

The system achieves rapid, accurate, and consistent sharpening with reduced flex, maintaining a constant bevel angle and removing minor defects, while accommodating tools with bends or warps, and allows for efficient processing of multiple tools with minimal operator intervention.

Abstract

A robotic sharpening system and method are provided for quickly and accurately sharpening cutting tools. The system of the invention employs a robotic arm that holds each cutting tool by its cutting blade rather than its handle, thereby reducing flexing during the sharpening process. This produces a more precise and consistent sharpening by consistently providing a uniform bevel on the knife edge regardless of minor imperfections (i.e., a bend or warping) on ​​the blade surface. Furthermore, it makes the system unaffected by the size or shape of the cutting tool's handle.
