Independent of the robot-Precision measuring robot scanning detection method

The present invention discloses a method of detecting robot scanning measurement accuracy independent of the robot. Hardware scan measurement of the robot of the present invention is constituted by a general industrial robot, scanning probe and an optical tracking system, first in the CAD software virtual assembly workpiece CAD model with the dedicated jig CAD model; then automatically planned scan measurement path; then in a real environment , measuring fixture with respect to the three-dimensional space of an industrial robot; then in the industrial robot simulation software based on the measurement result of the above steps, the adjustment fixture and the workpiece CAD model and the position of the scanning measurement path in the above step in planning; second measurement path shutter and collision analysis; or if there is collision blocked, adjusting the real environment the position of the workpiece and the jig, and repeat the above steps until collision unobstructed and otherwise, using the generated industrial robot motion program; Finally workpiece detection. Scan measurement of the robot of the present invention may be used directly for on-site production.
