Method for detecting surface pollution degree through ultrasonic wave and cleaning pollution

Abstract

The invention discloses a method for detecting the surface pollution degree through ultrasonic wave and cleaning the pollution. An ultrasonic transducer emits ultrasonic wave and receives the ultrasonic wave, and in pollution degree detection, the ultrasonic transducer emits sound surface wave with the frequency of F1, the sound surface wave is broadcasted along the cleaned surface and then is received by the ultrasonic transducer; when the pollution degree varies, the strength of the sound surface wave received by the ultrasonic transducer can be different, the strength of the output electric signals can be different, when the electric signals reach certain preset values, the ultrasonic transducer emits ultrasonic wave with the frequency of F2 to clean the surface, and after a period of cleaning, cleaning can be stopped for detecting again. By means of the method, the surface pollution degree can be detected ceaselessly, cleaning can be performed automatically according to the pollution degree, the surface can be always kept clean, damage to the surface can be reduced, and energy is saved.

Description

technical field [0001] The invention relates to a method for cleaning surfaces by using ultrasonic waves, in particular to a method for automatically cleaning surfaces by using ultrasonic waves according to the degree of surface pollution. Background technique [0002] During use, some objects will be polluted by the external environment to make the surface dirty, and the pollutants on the surface need to be continuously removed, such as car lights and car windows. Among the existing technologies, some technologies can only remove pollutants on the surface. For example, in the Chinese patent with the application number "02149762.1" and the title "Ultrasonic Cleaning Processor", a method for removing pollutants on the container wall is disclosed; some technologies Detecting pollutants on the surface, such as in the patent with the Chinese application number "200410033011" titled "Method and device for measuring surface pollutants in components in lithography devices", a radia...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following disadvantages: it cannot be cleaned according to the degree of pollution, and sometimes it is cleaned without cleaning, resulting in excessive cleaning and affecting the service life; sometimes surface pollutants need to be cleaned but cannot be removed in time; There is still a lack of a method that can directly detect the degree of surface contamination, and use this as a basis to clean the surface, combine detection technology with cleaning technology, and effectively reduce costs
