Abstract

An apparatus for dry-cleaning a light guide plate is provided to prevent a light guide plate from being damaged by particles attached to a brush by including a ventilation unit and an absorption unit. A ventilation unit blows away the particles caught in a brush(151) by using a nozzle(155) installed at a side of the brush and a compressor for supplying air to the nozzle. An absorption unit absorbs the particles having dropped from the brush by the ventilation unit, including a brush housing(131) and an absorption fan(133) installed at the end of the housing. A part of the brush housing is opened in a manner that a light guide plate(10) comes in contact with the brush. The brush and the nozzle are surrounded by the brush housing.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light guide plate dry cleaning apparatus, and more particularly, to a light guide plate dry cleaning apparatus capable of removing particles caught between hairs of a brush.

Generally, the light guide plate is processed to a predetermined size through a roughing process and a finishing process after the prism surface is formed in a manufacturing process, and then goes through a washing process to remove particles remaining in the cut portion.

The above-described cleaning process is largely divided into a dry cleaning method for removing foreign substances on the surface of the substrate using a brush and a wet cleaning method for washing the surface of the substrate by spraying a cleaning liquid such as pure water on the surface of the substrate at a high pressure. .

However, in the case of the wet cleaning method, when the cleaning liquid is sprayed onto the light guide plate, fine dust is swept into the cleaning solution and hits the light guide plate, or the particles falling on the light guide plate drop and scratch the surface of the light guide plate. There was a problem.

Therefore, in the case of the light guide plate, a dry cleaning method using only a brush in a clean room is effective.

However, according to the conventional dry cleaning method, the problem of the wet cleaning method could be solved, but in the dry cleaning method, particles separated from the light guide plate when being cleaned using the brush are caught by the brush of the brush and hit the light guide plate being washed to scratch the light guide plate. There was a problem that occurs.

The present invention has been made to solve the above-described problems, by using a blowing means and a suction means to remove particles caught between the hair of the brush from the brush, to increase the cleaning efficiency and damage to the light guide plate by the particles caught in the brush. It is an object of the present invention to provide a light guide plate dry cleaning device which can be prevented.

A light guide plate dry cleaning device for achieving the above object, the light guide plate dry cleaning device for cleaning the end of the light guide plate using a brush, comprising: blowing means for blowing particles caught between the hair of the brush; And suction means for sucking the particles away from the brush by the blowing means.

In the above configuration, the blowing means is a nozzle installed on one side of the brush; And a compressor for supplying wind to the nozzle.

In addition, the suction means may be partially opened so that the light guide plate is in contact with the brush, the brush housing surrounding the brush and the nozzle; And a suction fan provided at the end of the housing.

In addition, the brush is characterized in that the antistatic brush containing the nylon with copper powder added.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the light guide plate dry cleaning device of the present invention.

1 is a cross-sectional view of a light guide plate dry cleaning apparatus according to an embodiment of the present invention, Figure 2 is a plan view of a light guide plate dry cleaning apparatus according to an embodiment of the present invention.

1 and 2, the light guide plate dry cleaning apparatus according to the exemplary embodiment of the present invention cleans the end of the light guide plate 10 using a brush 151, a transfer means, a washing means, a blowing means, and the like. It comprises a suction means.

First, the conveying means is a means for transferring the light guide plate 10 which has undergone roughing and finishing process to the place where the cleaning means provided with the brush 151 is located, the adsorption plate 111 fixing the light guide plate 10, and the adsorption plate 111. It consists of a general driving unit 113 to move.

The adsorption plate 111 and the driving unit 113 described above are achieved by a general adsorption plate and a driving unit used in the light guide plate manufacturing process, the driving unit 113 may be achieved by various means such as a cylinder or a motor.

The next cleaning means is a means for cleaning the end of the light guide plate 10 after roughing and finishing process, the brush located at the upper and lower ends of the light guide plate 10 to remove particles adhering to the end of the light guide plate 10 ( 151 and the motor 153 for rotating the brush 151 at high speed.

At this time, the brush 151 described above is preferably used for the anti-static brush made of nylon (copper) is added, the motor 153 is achieved by a general motor.

Next, the blowing means is a means for blowing particles caught between the hair of the brush 151, the compressor is installed on one side of the brush 151 to supply wind to the nozzle 155 and the nozzle 155 is injected with the wind ( 157).

At this time, the nozzle 155 and the compressor 157 are connected to the nozzle tube 159. The nozzle 155, the nozzle tube 159, and the compressor 157 described above are a general nozzle and a nozzle for compressing air and spraying at high pressure. Is achieved with a tube and a compressor.

Therefore, by using the blowing means of the present invention, it is possible to apply high-pressure wind to the brush 151, it is possible to easily remove the particles stuck to the brush 151.

Next, the suction means is a means for sucking the particles away from the brush 151 by the blowing means, and a part of the light guide plate 10 is opened so that the light guide plate 10 can contact the brush 151, and the brush 151 and the nozzle 155 are opened. The brush housing 131 and the suction fan 133 provided at the end of the brush housing 131 are formed.

The brush housing 131 described above may be made of plastic or iron, and it is desirable to make the brush housing 131 as small as possible to increase the suction force of the suction fan 133, and the suction fan 133 is achieved as a general fan.

On the other hand, the brush 151 is spaced apart from the light guide plate 10 so as not to interfere with the movement of the light guide plate 10, the brush 151 is preferably moved in contact with the end of the light guide plate 10 during cleaning, the brush This is achieved by providing a general Cartesian robot 170 that can move the housing 131 from side to side.

Reference numeral 200 in the drawing is a process transfer apparatus after transferring the washed light guide plate 10 to a post process.

3 is a partially enlarged view of a light guide plate dry cleaning device according to an embodiment of the present invention, the upper and lower pairs of brushes 151 for cleaning the end of the light guide plate 10 are rotated in the brush housing 131, and the brush ( One side of the 151 is provided with a nozzle 155 for injecting wind to remove particles stuck to the brush 151 and a nozzle tube 159 for guiding the wind generated from the compressor 157 to the nozzle 155. At the end of the brush housing 131, a suction fan 133 for sucking particles separated from the brush 151 is provided.

Therefore, the end of the light guide plate 10 is washed by the brush 151 is rotated, the particles that are caught in the brush 151 of the particles away from the light guide plate 10 during the cleaning falls from the brush 151 by the blowing means, Thereafter, all the particles in the brush housing 131 are removed to the outside of the brush housing 131 by the suction means.

According to the present invention, it is possible to prevent damage to the light guide plate 10 washed by the particles caught in the brush 151, thereby increasing the cleaning efficiency and significantly reducing the rate of defective products.

In particular, in the case of using the antistatic brush mentioned in the detailed description, it is possible not only to prevent the generation of static electricity during cleaning, but also to effectively remove particles between the prism acid formed on the light guide plate.
