Automatic adhesive force testing system

Abstract

The invention aims to provide an automatic adhesive force testing system which comprises a first feeding mechanism arranged on a fixed plate and a workbench slidably connected to the fixed plate, an output end of the first feeding mechanism is connected with an input end of the workbench, and a gridding mechanism, a tearing arm and an adhesive mechanism are sequentially arranged above the workbench in the sliding direction. According to the invention, the problems of high labor cost, large personal error and low efficiency due to the fact that the division, adhesion, adhesive tape tearing andreading of an adhesive force test in the prior art are all completed manually are solved.

Description

technical field [0001] The invention belongs to the field of adhesion testing, in particular to a material surface coating adhesion testing system. Background technique [0002] Metals and composite materials are widely used in various fields. In many fields, the surface needs to be coated with a coating. After the coating is applied to the material, the adhesion of the coating needs to be tested. Coating adhesion test can simulate the change of coating adhesion characteristics on the surface of materials under specific working conditions, and provide reference for coating damage mechanism research, performance optimization, process improvement, etc. [0003] As described in the patent application document with the publication number: CN 103543101 A, a method for testing the surface adhesion of electrical appliances is suitable for testing the adhesion of paint on the surface of electrical appliances, including the following steps: take out the sharp blade, set the blade ang...

AI Technical Summary

Problems solved by technology

[0005] 1. Scratching, pasting and tearing tapes, the readings are all done manually, and the labor cost is high;

[0006] 2. The grids drawn by different people are different, and the 90-degree included angle required by the standard is quite different, and the difference is too large due to human factors. In the final reading, the damage is identified by eyes, and the human error is relatively large;

[0007] 3. Manually complete the entire testing process, which is inefficient
