A kind of release film wear resistance testing device

Abstract

The invention discloses a device for testing the wear resistance of a release film, which relates to the technical field of testing mechanisms. One side of the base is rotatably connected with a release film roll, the outer circumference of the release film roll is wound with a release film, the base is fixedly connected to one end of the guide rod through a support rod, and the other end of the guide rod is connected to the other end of the base. The transmission mechanism on the side is fixedly connected, and the release film is moved to the horizontal chute at the bottom of the guide rod through the pull-out mechanism. There is a friction chuck for clamping the release film directly under the chute of the guide rod, and the friction chuck is fixed with the transmission mechanism. connected, and friction mechanisms on both sides of the guide rod are respectively arranged on the base. In the invention, the elastic baffle drives the sliding rod to move in the vertical direction of the movable through hole of the casing, the sliding rod drives the slider to move in the vertical direction inside the casing, and under the action of the first spring and the second spring, the slider drives The sliding bar can be reset in time, which can achieve the effect of increasing the number of movements of the sliding bar in the vertical direction and increasing the number of grinding times of the friction head in the vertical direction.

Description

technical field [0001] The invention belongs to the technical field of release film detection equipment, and particularly relates to a release film wear resistance detection device. Background technique [0002] Release film refers to a film that can be distinguished on the surface of the film. The release film is not sticky or slightly sticky after contact with a specific material under limited conditions. The main function of the release film in FPC production is isolation, filling. , protection, easy to peel off. [0003] After the release film is produced, various properties of the release film need to be tested. In the prior art, the Chinese invention patent with the application number of CN200910156802.0 discloses a release film detection device. This invention detects the solvent resistance, abrasion resistance and release agent adhesion of the release film. A piece of release film or a whole piece of release film is fixed on the stage corresponding to the respectiv...

AI Technical Summary

Problems solved by technology

To sum up, the present invention implements quantitative strength on the surface of the release film through the release film detection device instead of manual indeterminate reciprocating rubbing, so that the subsequent force measurement results are uniform and standardized, and human factors are eliminated. The influence of the performance test results, but for the detection of the wear resistance of the release film, it is still tested by the tensile machine test, and the test results are not accurate
