Problems solved by technology
[0004] The existing detection method of fluorescence brightness of fluorescent penetrant needs to be diluted with volatile and flammable liquid acetone or alcohol, and detected with the help of filter paper. There are many operation steps, cumbersome operation and long detection time.
Existing detection methods for fluorescence brightness of fluorescent penetrants all require accurate measurement of fluorescent penetrant, which increases the complexity of the detection process, and the detection accuracy is affected by the measurement accuracy of fluorescent penetrant
The acetone and alcohol used in the existing detection methods are flammable liquids, which are dangerous to store and use, and are not conducive to mobile detection
The diluted fluorescent penetrant and the used filter paper both form a certain waste and increase the burden on the environment

The invention discloses a fluorescent penetrant fluorescence brightness detection method. The method comprises the following steps: S10, forming fluorescent penetrant into a liquid layer with a set thickness; S20, directly irradiating the fluorescent penetrating fluid by using ultraviolet rays; and S30, detecting the brightness of fluorescence emitted by the fluorescent penetrant. The method can be used for directly detecting the fluorescence intensity of the fluorescent penetrating fluid, and is simple in detection process and good in detection effect. The invention also provides a fluorescent penetrant fluorescence brightness detection device, which can realize the method provided by the invention.
Description
technical field [0001] The invention relates to the detection of fluorescence brightness, in particular to a method for detecting the fluorescence brightness of a fluorescent penetrant, and also relates to a device for detecting the fluorescence brightness of a fluorescent penetrant. Background technique [0002] Fluorescent penetrant testing is a kind of application of fluorescent penetrant on the surface of the test piece, so that the fluorescent penetrant penetrates into the tiny defects opening on the surface of the test piece, and uses a remover to remove the fluorescent penetrant on the surface of the test piece, and then passes through the imaging agent It is a non-destructive testing method that makes the fluorescent penetrant in the tiny defect seep back to the surface of the test piece, and uses a black light lamp to detect the fluorescence emitted by the fluorescent penetrant at the defect to detect the opening defect on the test piece surface. The fluorescence br...
