[0002] Alloy parts are usually used in automobiles, aircraft and other mechanical equipment. Alloys usually refer to materials made of two or more metals or a mixture of metals and non-metallic elements. Using alloys when manufacturing parts can improve their strength, wear resistance and corrosion resistance, thereby increasing the service life of the parts. Alloy part surface defect detection equipment usually refers to equipment used to detect surface defects of metal parts, which uses optical principles to detect surface defects, such as using a high-resolution camera or microscope to observe and record defects.

[0003] After the current surface defect detection device for alloy parts has completed the inspection of alloy parts, it is unable to mark the defective or damaged alloy parts, which makes it easy for workers to get confused when classifying complete and defective alloy parts.

When the surface of the alloy parts on the conveyor belt is damaged, the conveyor belt moves the alloy parts to the printing plate to descend, the hydraulic cylinder drives the printing plate to descend, and the printing plate leaves a mark on the surface of the damaged alloy parts, and the staff takes away the alloy parts with the mark on the surface for processing.
