Grinding belt and grinding device

Abstract

The invention provides a grinding belt and a grinding device. The grinding belt comprises a belt-shaped flexible base material layer and a grinding layer arranged on the flexible base material layer; the grinding layer comprises a plurality of grinding units repetitively distributed in the extension direction of the flexible base material layer; each grinding unit comprises a foreign body cutting area, a foreign body guiding and discharging area and a foreign body eliminating area; each foreign body cutting area comprises a first grinding pattern capable of cutting foreign bodies on the surface of a base plate; each foreign body guiding and discharging area comprises a second grinding pattern capable of guiding the foreign bodies on the surface of the base plate to a predetermined area; each foreign body eliminating area comprises a third grinding pattern capable of eliminating the foreign bodies on the surface of the base plate; and the foreign body cutting areas, the foreign body guiding and discharging areas and the foreign body eliminating areas are sequentially distributed in the extension direction of the flexible base material layer. According to the grinding belt, the grinding layer on the grinding belt is divided into the foreign body cutting areas, the foreign body guiding discharging areas and the foreign body eliminating areas, and the foreign body cutting areas, the foreign body guiding discharging areas and the foreign body eliminating areas have different patterns correspondingly, the foreign bodies can be effectively eliminated, and the effect of grinding is good.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a grinding belt and grinding equipment. Background technique [0002] In the TFT-LCD (thin film transistor-liquid crystal display, thin film transistor-liquid crystal display) manufacturing process, the surface of the glass substrate needs to be cleaned before attaching the polarizer to ensure the yield of attaching the polarizer. [0003] At present, the existing glass substrate grinding equipment mainly adopts the grinding belt cleaning method. The grinding belt is driven by a motor to grind the glass substrate, and the high-pressure water vapor two fluid is sprayed on the upper end of the working area of ​​the grinding belt to make the grinding belt and the glass substrate contact. Ensure a certain contact pressure. [0004] However, in the prior art, the pattern of abrasive particles on the grinding belt is single, the cleaning ability is weak, and foreign matter on the gla...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, the pattern of abrasive particles on the grinding belt is single, the cleaning ability is weak, and foreign matter on the glass surface cannot be effectively removed, and during the cleaning process, the foreign matter that is ground away is easy to gather on the surface of the grinding belt, which is harmful to the glass surface. secondary pollution, resulting in a decline in the cleaning ability of the grinding belt, resulting in a low service life of the grinding belt, poor grinding effect, and a decrease in yield
