Dye penetration inspection apparatus and dye penetration inspection method

Abstract

The invention provides a dye penetration inspection apparatus and a dye penetration inspection method. The apparatus comprises a workbench and an injection bench; the workbench comprises a peripheral pedestal and a supporting body at the center of the pedestal; the surface of the supporting body is provided with a translational guide rail; a pallet is disposed on the translational guide rail; the injection bench is disposed at the side of the opening of the pedestal, and comprises a rotating disk and a stepping motor; a position sensing switch is disposed on the stepping motor and used to output the position signal of a reagent bottle to a PLC controller controlling the rotation of the stepping motor; a pick-up head is disposed above the supporting body; a cleanable special pattern is coated at the center of the upper surface of a sample; and the pick-up head acquires the image of the sample, an image processing module makes the translational guide rail move according to the position of the special pattern, and thus the sample is sent to a predetermined spraying position. The dye penetration inspection apparatus and the dye penetration inspection method help to realize automation of dye and inspection and reduce pollutions to 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...
