Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions of the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0035] see Picture 1-1 and Figure 1-2 , a cutting device provided by an embodiment of the present invention is used for a cross-cut test of a surface coating of a substrate 1, and it includes a support base 2, a substrate fixing assembly 3, a scraper 4 and a guide rail assembly 5. The support base 2 is used to fix the base plate 1 , the guide rail assembly 5 cooperates with the support base to form a first guide rail 511 and a second guide rail 512 , and the first guide rail 511 intersects the second guide rail 512 . In the surface coating scratch test, in order to obtain a standard right-angle grid, the first guide rail 511 may be set to be perpendicular to the second guide rail 512 . The guide rail assembly 5 is installed on the support base 2 to form a receiving space wi...

Abstract

The invention provides a cutting device for a gridding test of a surface coating of a substrate. The cutting device comprises a supporting base, a guide rail assembly and a scraper. The supporting base is used for fixing the substrate. The guide rail assembly is matched with the supporting base to form a first guide rail and a second guide rail; the first guide rail and the second guide rail are intersected; the guide rail assembly is mounted on the supporting base and forms an accommodating space together with the supporting base for accommodating the substrate. The scraper cuts the surface coating to the substrate along the first guide rail and the second guide rail so as to perform the gridding test. According to the cutting device provided by the invention, the cutting direction of the scraper is controlled by means of the guide rail assembly to obtain a standard grid pattern, and thus the success rate of the gridding test is increased.

Description

technical field [0001] The invention relates to the field of product surface coating detection, in particular to a cutting device for cross-cut test. Background technique [0002] TFT-LCD (Thin film transistor-liquid crystal display: thin film transistor-liquid crystal display) is a liquid crystal panel composed of a thin film transistor array substrate, a color filter array substrate and liquid crystal sandwiched between the two substrates. In the manufacturing process of the color filter array substrate, the color filter layer is coated on the glass substrate first, and then the color filter array substrate is obtained through exposure, development, etching and other processes. The adhesion of the color filter layer on the color filter array substrate to the glass substrate is one of the factors affecting the reliability of the liquid crystal panel. [0003] In the prior art, the cross-cut test of the color filter layer cut by hand is mostly used to detect the adhesion of...
