Problems solved by technology

[0003] Any method involving water inspection has obvious disadvantages, that is, after the inspection, the remaining water stains on the tailgate need to be cleaned, which is time-consuming and laborious
However, with the method of air pressure inspection, it is often only possible to draw the conclusion that there is leakage in the abnormal air pressure, but it is impossible to visually see which part is leaking.

Abstract

The invention, which belongs to the technical field of testing equipment, in particular relates to an ultrasonic detecting device and detecting method for an automobile resin tailgate. The detecting device comprises an electric cabinet and a detecting box disposed above the electric cabinet. The detecting box includes a lower box body and an upper cover plate. An ultrasonic detecting unit includesan ultrasonic transmitter and an ultrasonic connecting device. An automobile resin tailgate profiling bracket for supporting and carrying an automobile resin tailgate is arranged in the lower box body; a plurality of profiling support blocks for assisted supporting of the automobile resin tailgate are arranged in the lower box body. Besides, a positioning mechanism for positioning of the automobile resin tailgate is also arranged in the detecting box. According to the invention, on the basis of the ultrasonic detection principle, quality detection of the connection on the automobile resin tailgate and part connection sealing of the automobile resin tailgate is realized; problems of time and effort wasting for post-stage cleaning caused by water detection and low visibility of air pressuredetection are solved; the quality detection of the automobile resin tailgate becomes convenient; and the detection efficiency and accuracy are improved.

Description

technical field [0001] The invention belongs to the technical field of detection equipment, and in particular relates to an ultrasonic detection device and a detection method for an automobile resin tailgate. Background technique [0002] As we all know, the quality of sealing is an important indicator to test the quality of automotive resin tailgate. At present, the method of detecting the sealing of the tailgate is mainly to detect whether water or gas can pass through the glued area of ​​the tailgate, so as to judge whether the bonding is firm and whether the sealing is qualified. Specifically, by placing the tailgate in a simulated rain environment, check for water leakage; or place the tailgate in a closed space, and check whether the air pressure is abnormal by pressurizing; Apply bubble water around, and then check whether there are bubbles by blowing air. [0003] Any method involving water inspection has obvious disadvantages, that is, after the inspection, it is ...
