Cloth inspection machine and cloth inspection method using the same

Abstract

The invention provides a cloth inspection machine and a cloth inspection method using the same. The cloth inspection machine comprises a workbench for holding to-be-inspected cloth, a dust removal structure arranged above the workbench and used for removing first foreign matters in the to-be-inspected cloth in an absorbing manner, an inspection mechanism arranged above the workbench and used for inspecting the positions of second foreign matters in the to-be-inspected cloth, a scissors structure arranged above the workbench and used for removing the second foreign matters in the to-be-inspected cloth in a shearing manner, and a first driving structure which is respectively connected with the inspection structure and the scissors structure and is used for driving the scissors structure to move to the positions of the second foreign matters inspected and positioned by the inspection structure according to the inspection results of the inspection structure. The automatic scanning and inspection of the to-be-inspected cloth can be realized by the combination of the dust removal structure, the inspection structure and the scissors structure; excellent inspection results can be obtained, the manual inspection cost can be reduced and the detection time is shortened.

Description

technical field [0001] The invention relates to a rubbing process of a liquid crystal display device, in particular to a cloth inspecting machine and a cloth inspecting method using the cloth inspecting machine. Background technique [0002] In the manufacture of liquid crystal displays, the rubbing process is an essential process step. Such as figure 1 The schematic diagram of the structure shown in the rubbing process includes the step of rubbing the surface of the glass substrate 3 coated with the alignment agent PI with the rubbing roller 2 attached with the rubbing cloth 1 of the flannelette material to form an alignment film, and the surface of the alignment film passes through The friction of the rubbing cloth on the rubbing roller brushes out the grooves arranged in a certain direction, which has the ability to align the liquid crystal, so that the liquid crystal molecules of the liquid crystal layer are arranged according to a predetermined inclination angle.

Problems solved by technology

[0005] For tiny cottonseeds, it cannot be detected, and it is easy to miss;

[0006] During the rough inspection, the operator only uses a soft brush to clean the broken hairs on the edge of the friction cloth, but this method can easily sweep the broken hairs into the gaps between the cloth and wool, causing secondary pollution;

[0007] It is difficult to cut off the thicker cloth head. If it is cut off, the surrounding good cloth hairs will be easily damaged, causing greater damage to the cloth hairs and affecting the quality of the workmanship;

[0008] It will take a lot of time, and the manual inspection method is very easy to touch the hair surface and cause damage to the hair surface, resulting in a change in the direction of the hair, resulting in poor quality;

[0009] Each operator's operation method is different, and there is no unified system standard
