Pressing and tearing device and pressing and tearing method for delaminating rate test

Abstract

The invention relates to a pressing and tearing device and a pressing and tearing method for a delaminating rate test. The pressing and tearing device comprises a working platform, a pressing mechanism, an input unit, a pressure sensor, a tension sensor, a controller and a driving mechanism, wherein the working platform is used for carrying a to-be-tested sample; the pressing mechanism is arranged above the working platform, and synchronously rolls and horizontally moves relative to the working platform; the input unit is used for setting pressing force parameters and tearing force parameters through the input unit; the controller is respectively and electrically connected with the input unit, the pressure sensor and the tension sensor; the driving mechanism drives the working platform to ascend or descend under the control of the controller, and drives the pressing mechanism to synchronously roll and horizontally move relative to the working platform. When being used for performing pressing and tearing operation of the delaminating rate test, the device is high in repeatability and stability, the performances of materials can be accurately reflected, and the materials truly meeting requirements are screened out.

Description

technical field [0001] The invention relates to the field of peel rate testing, more specifically, to a pressing and tearing device and a pressing and tearing method for peeling rate testing. Background technique [0002] In the panel display industry, color displays mainly use RGB color filters for color display. However, due to the difference in adhesion, the RGB color resist may peel off to form bright spots on the display. This kind of bright spot has a great influence on the quality of the display screen, and it is a very serious defect of the display screen. Therefore, RGB color resistance and adhesion between substrates become key parameters for material evaluation. [0003] At present, the relatively mature method in terms of material evaluation and new product verification adhesion is the 100-grid scraper method. The general process of the 100-grid scraper method is: use the 100-grid scraper to make a cross pattern on the area to be tested, and then tape the area ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is that the existing test method and test equipment have different tearing forces and tearing angles of the adhesive tape and the adhesive tape, which lead to different processing conditions for the tests of different samples, resulting in large operational errors and repeatability. In order to solve the defects of poor performance and poor stability, a pressing and tearing device and pressing and tearing method for peeling rate test are provided
