Abstract

The present invention proposes a colored penetrating flaw detector, comprising: a workbench and a jetting platform; the workbench includes a peripheral base and a carrier in the middle of the base; a translation guide rail is arranged on the surface of the carrier, and a tray is placed on the translation guide rail; The spray table is arranged on one side of the fully open side wall of the base, and includes a turntable and a stepper motor; the stepper motor is provided with a position sensing switch, which outputs the position signal of the reagent bottle to the PLC controller, and the PLC controller Control the rotation of the stepping motor; a camera is arranged above the carrier, and the center of the upper surface of the sample is coated with a special pattern that can be cleaned. The camera collects the image of the sample, and the image processing module controls the The translation rail moves to transport the sample to the predetermined spraying position. The colored penetrant flaw detector and the automatic colored penetrant flaw detection method of the present invention realize the automation of colored flaw detection and reduce the pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a coloring penetrant flaw detector, and also relates to an automatic coloring penetrant flaw detection method. Background technique [0002] Colored penetrant testing is a method of non-destructive testing. It uses capillary phenomenon to detect wounds, cracks and defects on the surface of the workpiece, and can clearly detect the size, location and area of ​​​​cracks on the surface of the workpiece. Dye penetrant testing plays an increasingly important role in the quality assurance system of machinery, metallurgy, petroleum, chemical industry, railway, transportation, aerospace and defense industries. [0003] The coloring penetrant flaw detection method used today is to use the coloring penetrant flaw detection agent to detect the flaws of the test piece by manual means. Colored penetrant flaw detection agents include cleaning agents, penetrants, and imaging ag...
