Description

Dust-proof method for glass edger

The present invention relates to the field of liquid crystal displays, and more particularly to a dustproof method for a glass substrate edger. Background technique

Liquid crystal display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices on the market are backlight type liquid crystal display devices, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules in two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates, and the liquid crystal molecules are controlled to change direction by energization or not, and the light of the backlight module is refracted. Come out to produce the picture. Since the liquid crystal panel itself does not emit light, the light source provided by the backlight module needs to be used to display the image normally. Therefore, the backlight module becomes one of the key components of the liquid crystal display device. The backlight module is divided into a side-in backlight module and a direct-lit backlight module according to different incident positions of the light source. In the direct type backlight module, a light source such as a CCFL (Cold Cathode Fluorescent Lamp) or an LED (Light Emitting Diode) is disposed behind the liquid crystal panel, and a surface light source is directly formed and supplied to the liquid crystal panel. The side-lit backlight module has a backlight LED strip (Light bar) disposed on the edge of the back panel behind the liquid crystal panel, and the light emitted by the LED strip light enters the light from the side of the light guide plate (LGP, Light Guide Plate). The surface enters the light guide plate, is reflected and diffused, and is emitted from the light exit surface of the light guide plate, and is supplied to the liquid crystal panel through the optical film group to form a surface light source.

The quality of a liquid crystal display depends first on its panel, because the quality of the panel directly affects the viewing effect of the screen, and the LCD TV panel accounts for more than half of the cost of the whole machine, which is the main factor affecting the cost of the LCD TV. The LCD panel can largely determine the parameters of the LCD such as brightness, contrast, color, and viewing angle.

However, in the processing of the liquid crystal panel, whether it is a single-plate edging machine or a double-plate edging machine, when the glass substrate is edging, glass swarf is generated, which is unavoidable, and at the same time, on the glass substrate.

Referring to FIG. 1 to FIG. 3, the present invention provides a dustproof method for a glass substrate edger, which comprises the following steps:

Step 101, providing an edger and a glass substrate 6 to be edged, the edger comprising: an edger body (not shown), a dustproof spacer 2 mounted on the body of the edger, mounted on the mill a vermiculite 4 on the edge machine body and a blow pipe (not shown) mounted on the edge of the edging machine and disposed in front of the gangue 4, the edging machine body having a platform 8 for carrying the glass substrate, the The dust separator 2 is disposed on the upper portion 8 of the platform. When the glass substrate 6 to be edged is disposed on the platform 8, it is at an angle to the horizontal direction, and the glass substrate 6 to be edged and the lower end of the dustproof separator 2 form a first a slit 28, the vermiculite 4 is disposed relative to the glass substrate 6 to be edged;

The platform 8 includes a polishing zone 10 and a non-abrasive zone 20, and the dustproof barrier 2 is disposed between the polishing zone 10 and the non-abrasive zone 20. By placing the dustproof spacer 2 between the polishing zone 10 of the platform 8 and the non-polishing zone 20 and leaving only a small first slit 28 between the dustproof spacer 2 and the glass substrate 6 to be edged, The grinding zone 10 is separated from the non-polishing zone 20, and the particles generated by the edging operation do not fall onto the glass substrate 6 to be edging of the non-abrasive zone 20, thereby preventing the particles generated during the grinding from being scratched. The edge glass substrate 6 ensures the quality of the polished glass substrate.

The size of the first slit 28 between the glass substrate 6 to be edged and the dustproof separator 2 is 0.5- 2mm, preferably 1mm, the first slit 28 can be set as small as possible without affecting the processing efficiency and the quality of the glass substrate 6 to be edged, which minimizes the drop of particles generated during grinding. The probability of being in the non-abrasive zone 20.

The edging machine body is an existing single-plate edging machine body or a double-plate edging machine body.

The cooling water introduced from the dustproof partition 2 can be automatically flowed to the processing of the vermiculite 4 by gravity, thereby moisturizing the vermiculite 4, and further washing away the particles generated when the edges are rubbed.

Step 103, introducing cooling water from the dustproof partition 2, the cooling water 9 in the first gap

28 water curtains are formed, and 4 pieces of vermiculite are processed along the glass substrate 6 to be edged;

In the preferred embodiment, the dustproof partition 2 includes: first, second, and third dustproof partitions 22, 24, and 26, and the first, second, and third dustproof partitions 22 24 and 26 are arranged side by side, and a second slit 29 and a third slit 30 are formed between the first and second dustproof partitions 22 and 24 and between the second and third dustproof partitions 24 and 26, respectively.

Step 104: The blowing air pipe is formed to form a curtain area 7, and the remaining water left at the edge of the glass substrate 6 to be edged is blown off;

During the actual grinding process, the glass substrate 6 to be edging will rotate. If the edge of the glass substrate 6 is to be ground, there is residual water after grinding, and the particles in the glass substrate will be slippery with the remaining water due to the rotation of the glass substrate 6 to be edging. The pattern area of the edging glass substrate 6 is entered, thereby damaging the glass substrate 6 to be edging. In response to the above situation, the blow pipe is disposed in front of the vermiculite 4, thereby forming a wind curtain region 7 in front of the vermiculite 4, the blow pipe blowing a high pressure (CDA) gas, and then attaching the tape to the edge of the glass substrate 6 to be edged. The residual water of the particles is blown off to ensure that the particles do not slide with the remaining water into the pattern area of the glass substrate 6 to be edged.

Step 105: Start the vermiculite 4, perform grinding, and complete the grinding process. In the process, the particles generated by the grinding are blocked by the water curtain and the dustproof partition 2 to prevent it from falling onto the glass substrate 6 to be edged, and the air pipe is blown at the same time. A curtain region 7 is formed to blow off the remaining water remaining at the edge of the glass substrate 6 to be edged.

In the present invention, the dust-proof partition 2 and the water curtain block the particles generated during the grinding, and the air is blown. The tube blows off the residual water with particles on the edge of the glass substrate 6 to be ground, so that the pattern on the glass substrate 6 to be polished is well protected during the grinding process to avoid being scratched.

In summary, the present invention provides a dustproof method for a glass substrate edger, which is provided with a dustproof partition and a water curtain between a grinding area and a non-polishing area of the platform, thereby separating the grinding area from the non-polishing area. Opening, and a blowpipe is arranged in front of the vermiculite, so that the residual water with particles attached to the edge of the glass substrate to be edged is blown off, preventing the residual water from sliding into the pattern area of the glass substrate to be edged, thereby being able to The particles generated when the glass substrate to be edging is edged are prevented from falling onto the glass substrate, and the pattern on the glass substrate to be edging is scratched to ensure the quality of the polished glass substrate.
