Press and tear device and press and tear method for peeling rate test

Abstract

A press tearing device and press tearing method for testing a peeling ratio. The press tearing device (1) comprises a workbench (15) used for bearing a sample to be tested, and also comprises: a press mechanism (17), the press mechanism (17) being arranged above the workbench (15) and conducting synchronous relative rolling and translation relative to the workbench (15); an input unit (16) used for setting a press pressure parameter and a tearing force parameter through the input unit (16); a pressure sensor (18) and a tension sensor (19); a controller (13) electrically connected to the input unit (16), the pressure sensor (18) and the tension sensor (19) respectively; and a drive mechanism used for driving the workbench (15) to rise or fall under the control of the controller (13) and driving the press mechanism (17) to conduct synchronous relative rolling and translation with the workbench (15). When a press tearing operation for testing a peeling ratio is conducted using the press tearing device, the repeatability and stability are good, the performance of materials can be accurately reflected, and materials truly meeting the requirements can be 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
