The above-mentioned work is repeated after the gear workpiece is close to the reagent fluted disc 3 positioned at the step of the middle section and the tail section of the conveyer belt 1, wherein the difference is that the coloring agent sprayed out by the U-shaped spray head 32 is developer in the process, finally the gear workpiece after the coloring is finished is shot and recorded by the flaw detection probe 6, and then the flaw detection work of the gear workpiece is finished by detecting and analyzing the image information uploaded by the flaw detection probe 6 by means of an external computer.
