Glue adhesion testing device and testing method thereof

Abstract

The invention discloses a glue adhesion testing device which comprises a cabinet body, machine shells are welded to the surfaces of the two sides of four supports of the cabinet body through supporting plates respectively, a power distribution box is assembled on the surface of one side of each machine shell through bolts, and a single-chip microcomputer is arranged on the inner wall of the powerdistribution box. The single-chip microcomputer is electrically connected with a control button through line cooperation, the single-chip microcomputer is electrically connected with a timer arrangedon the machine shell through line cooperation with the control button, and the single-chip microcomputer is electrically connected with a pneumatic pump arranged in the cabinet body through line cooperation with the control button. And the single-chip microcomputer is electrically connected with an air cylinder arranged on the cabinet body through cooperation of a circuit and a control button. According to the invention, a pneumatic pump is matched with the box body structure to pressurize an adhesive to be tested, and an air pressure is used for applying a force, so that the whole adhesive can be fully and uniformly stressed, and the stability and reliability of the whole test are further ensured.

Description

technical field [0001] The invention belongs to the technical field of adhesion degree detection, and in particular relates to a glue adhesion degree test device and a test method thereof. Background technique [0002] Glue is an intermediate that connects two materials, mostly in the form of water, belonging to the category of fine chemicals, with a wide variety, mainly classified by adhesive, physical form, hardening method and adherend material. The common ones are instant glue, epoxy resin bonding, anaerobic glue, UV glue, hot melt adhesive, pressure sensitive adhesive, latex and so on. [0003] During the processing of the workpiece or the output of the glue, it is necessary to test the key performance of the adhesiveness of the glue. When testing the adhesive force, it is usually necessary to use the adhesive to be tested ( Such as glue) is bonded to make a test sample, and then the test sample is applied with a shear force along the bonding surface and / or a pulling f...

AI Technical Summary

Problems solved by technology

[0004] Common testing devices generally have a relatively simple structure. The shear force and / or tension applied to the test sample is often uneven in the direction of the force, and the magnitude of the force is not easy to control. In addition, the force applied by the hydraulic cylinder may vary due to Factors such as the quality of the adhesive or external bumps lead to damage to the matrix of the adhesive, which in turn affects the normal test work. There may be large deviations during the test. At the same time, the test steps are more complicated, the operation efficiency is low, and it cannot be synchronized.
