Dust protection method for glass substrate edge polishing machine

Abstract

The present invention provides a dust protection method for glass substrate edge polishing machine, which includes (1) providing an edge polishing machine and a glass substrate to be polished, wherein a dust protection board is arranged above a platform bearing a glass substrate to form a first gap therebetween and an air blow tube is provided in front of a grind stone; (2) fixing the glass substrate on the edge polishing machine; (3) introducing cooling water from the dust protection board to form a water curtain at the first gap; (4) activating the air blow tube to form an air curtain region; and (5) activating the grindstone to set out a grinding operation. The dust protection board and the water curtain block particles generated in grinding and the air curtain region blows residual water that contains particles off edges of the glass substrate.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to the field of liquid crystal display, and in particular to a dust protection method for glass substrate edge polishing machine.[0003]2. The Related Arts[0004]Liquid crystal display (LCD) has a variety of advantages, such as thin device body, low power consumption, and being free of radiation, and is thus widely used. Most of the LCDs that are currently available in the market are backlighting LCDs, which comprise a liquid crystal panel and a backlight module. The operation principle of the liquid crystal panel is that liquid crystal molecules are interposed between two parallel glass substrates and a plurality of vertical and horizontal fine electrical wires are arranged between the two glass substrates, whereby the liquid crystal molecules are controlled to change direction by application of electricity in order to refract light emitting from the backlight module for generating images.

AI Technical Summary

Benefits of technology

The present invention provides a method for edge polishing glass substrate using a machine that prevents particles generated during the process from scratching the substrate. This is achieved by using a water curtain and a dust protection board to separate the grinding and non-grinding zones. Additionally, an air blow tube is used to remove residual water left at the edges of the substrate to prevent it from flowing to the pattern region. These measures prevent particles generated during edge grinding from scratching the patterns of the substrate and ensuring the quality of the finished product.

Problems solved by technology

In addition, the panel of a liquid crystal television takes more than 50% of the television cost and is the key factor that affects the manufacturing cost of the liquid crystal television.

Further, since the patterns of the glass substrate are exposed, they are susceptible to influence by particles.

Thus, the glass chips generated during edge polishing of a glass substrate may cause severe damage to the patterns of the glass substrate, easily resulting in harmful situations of defects and scratching of the glass substrate.
