Description
Technical Field
The invention relates to a gluing film thickness detection technology, in particular to a method for rapidly detecting the thickness of glue applied to an automobile air conditioner pipe joint.
Background
The existing automobile air-conditioning pipe joint is generally required to be subjected to gluing treatment, and many automobile manufacturers have high requirements on gluing and need to clearly measure the thickness of glue applied to the automobile air-conditioning pipe joint. The traditional method for detecting the thickness of glue coated on the automotive air conditioner pipe joint comprises two methods, namely a metallographic embedding method, wherein a joint part coated with the glue is longitudinally cut, a cut surface is embedded, polished and measured by observing through a microscope. The method can only observe one section, has no way of observing the thicknesses of other parts, has complex operation procedures, has higher requirements on operators, and needs to consume a large amount of manpower, material resources and time; the other method is to use a film thickness gauge to directly detect on the curved surface, and the film thickness gauge is usually specially used for plane detection, and the measurement error of the small-radius curved surface body is very large, so the method is obviously not suitable.
Disclosure of Invention
The invention provides a method for detecting the thickness of glue coated on a pipe joint of an automobile air conditioner, aiming at overcoming the defects of the technical problems and completely solving the technical problems.
The technical scheme for solving the technical problems is as follows:
a method for rapidly detecting the thickness of glue coated on a pipe joint of an automobile air conditioner comprises the following steps:
(1) preparing 5-15% sodium hydroxide aqueous solution;
(2) cutting an opening on the automobile air-conditioning pipe joint by using a blade, cutting the glue film thoroughly, then completely immersing the automobile air-conditioning pipe joint into the sodium hydroxide aqueous solution prepared in the step (1), and keeping for 1-3 minutes;
(3) taking the automobile air conditioner pipe joint out of the sodium hydroxide water solution, washing with clear water, and slightly separating the joint of the glue film and the automobile air conditioner pipe joint by using a blade until the glue film can be completely stripped from the automobile air conditioner pipe joint;
(4) using a sheet tray to hold the peeled glue film, enabling the glue film to be completely opened and be flatly laid on the sheet tray, and naturally drying the glue film;
(5) and after the glue film is completely dried, measuring the thickness of the glue film by using a coating thickness gauge.
Further, the sheet-shaped tray in the step (4) is made of plate glass, paper, plastic sheets and other sheet-shaped objects.
The invention has the beneficial effects that:
the invention adopts a chemical method, uses the sodium hydroxide aqueous solution to separate the glue film from the aluminum tube, and because the sodium hydroxide aqueous solution and the aluminum alloy can react violently, the glue film can not react with the sodium hydroxide aqueous solution. The present invention allows the film of glue to be removed from the tube intact for observation and measurement, and at any point (B, C, D ….) on the film of glue, as shown in figure 2. The technical problem that the value of one point (A) can only be measured in the traditional measuring mode is solved, as shown in the attached figure 1.
