Embodiment Construction

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings. Obviously, the specific details described below are only some of the embodiments of the invention, and the invention can also be practiced in many other embodiments than those described herein. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or inte...

Abstract

The invention relates to an automatic detection method for gluing, which is applied to glue detection in industrial products and comprises the following steps: emitting detection waves and receiving echo signals; performing data processing on the echo signal, and comparing the echo signal with a preset threshold value; and the comparison result is transmitted to the industrial controller. According to the technical scheme provided by the invention, the transmitted ultrasonic waves penetrate through the measured objects, the ultrasonic waves can be reflected when penetrating through substances with different impedances due to different materials and different impedances of the measured objects, the scattering attenuation and the absorption attenuation of glue are far greater than those of steel, and the echo attenuation speeds are obviously different. Signal emission and recovery are carried out through the ultrasonic probe, data processing is carried out on echo signals, the echo signals are compared with a preset threshold value, whether gluing sequence jumping occurs or not is judged by detecting the echo attenuation rate, and targeted detection on glue is achieved.

Description

technical field [0001] The present invention relates to the technical field of industrial production, and in particular, to a method and device for automatic detection of gluing and a computer-readable storage medium. Background technique [0002] The automobile welding workshop uses a lot of various glues (such as sealant, structural glue, hemming glue, shock absorption glue). . At present, there is no direct method for online detection of glue leakage. Manual offline detection is often used, and pre-inspection bench detection is added after the glue application. With the further improvement of the automation rate of automobile welding workshops, especially the rise of black light factories, it is very necessary to invent a sensor that can detect whether glue leaks online. Existing ultrasonic detection methods, most ultrasonic spot welding flaw detection sensors, are used in spot welding process solder joint quality detection in various industries. The minimum gain, the ...
