Abstract

PROBLEM TO BE SOLVED: To eliminate the intrusion of dust generated from a driving system into waste water to reduce the frequency of repair or replacement of a circulating filter when reusing the waste water after washing by separating parts for housing conveying/driving system of a glass substrate and a glass substrate washing part by water barrier partition plates. SOLUTION: Both glass substrate 1, 2 for a liquid crystal cell are conveyed, held between both upper and lower conveying roller groups 3, 4. The front and back surfaces of both glass substrates 1, 2 each are sprayed with washing liquid from both upper and lower spray pipes 13, 14 and are brush-washed by a washing brush. Furthermore, waste water after washing is recovered in a waste water recovering part 19 and is stored in a reusing tank through a waste line and an impurity collecting filter. In this case, both driving system housing parts 20, 21 and a washing part 22 are separated in a closed state by both water barrier partition plates 23, 24. In this way, wear dust or time particles generated from gears or worn parts of a driving system are prevented from introducing into result waste water of washing liquid.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass substrate cleaning apparatus for cleaning a glass substrate used for a liquid crystal cell or the like. Needless to say, the present invention can also be used as an apparatus for cleaning a thin and thick glass substrate used other than a liquid crystal cell.

[0002]

2. Description of the Related Art Heretofore, a partition between a driving system for driving a transport roller for transporting a glass substrate and a range (cleaning section) for cleaning the glass substrate has not been completed. Therefore, when reusing waste water after washing, dust generated from the drive system, particularly wear dust generated by meshing of the drive gears, is mixed into the waste water, and the circulation filter must be frequently cleaned or replaced. did not become.

[0003]

According to the present invention, a sealing partition plate is provided between a driving system for driving a transport roller for transporting a glass substrate and an area (cleaning section) for cleaning the glass substrate. Thus, the drive system housing section and the cleaning section are completely separated. With such a structure, when reusing waste water after washing, dust generated from the drive system, particularly wear dust generated due to engagement of the drive gear, does not enter the waste water, and the circulation filter It is an object of the present invention to provide a glass substrate cleaning apparatus capable of extremely reducing the degree of maintenance or replacement of the glass substrate.

[0004]

The present invention is characterized in that a driving system housing section for housing a driving system for transporting a glass substrate and a washing section for washing the glass substrate are separated by a waterproof partition plate. A plurality of the partition plates are provided, and a plurality of the drive system storage portions are provided.

[0005]

According to the present invention, a drive system for driving a transport roller for transporting a glass substrate, and a sealing partition plate provided between an area for cleaning the glass substrate (cleaning unit), thereby storing the drive system. And the cleaning section are completely separated,
When the waste water after washing is reused, dust generated from the drive system does not enter the waste water, and the degree of maintenance or replacement of the circulation filter can be extremely reduced.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A drive system accommodating section for accommodating a drive system for transporting a glass substrate and a washing section for washing the glass substrate are partitioned by a waterproof partition plate, and a plurality of the partition plates are provided. The glass substrate cleaning apparatus having a plurality of drive system housings is specifically and concretely described based on the following embodiments.

1 and 2 show schematic views of a glass substrate cleaning apparatus according to an embodiment of the present invention. FIG. 1 is a schematic view from the front, and FIG. 2 is a schematic view from the side. FIG. First, the state of transport of the glass substrate will be described with reference to these drawings. Glass substrates 1 and 2 for liquid crystal cell
Is sandwiched between the upper transport roller group 3 and the lower transport roller group 4 and transported in the right arrow (→) direction in FIG.
These rollers are provided with holding elastic members 5 to 12, respectively, so that they can be held and conveyed without damaging the glass substrate surface and further preventing vertical vibration.

Next, a brief description will be given of a cleaning liquid reuse line. An upper spray pipe 1 is provided on the upper and lower surfaces of the glass substrates 1 and 2 when the glass substrate is nipped and transported.
The cleaning liquid is sprayed from 3 and the lower spray pipe 14,
The glass substrate surface is brush-cleaned by the cleaning brushes 15 to 18. The waste water after the washing is collected by the waste water collecting part 19 and stored in a reuse tank (not shown) through a drain line and an impurity collecting filter (not shown).
The cleaning liquid stored in the reuse tank is sprayed from the upper spray pipe 13 and the lower spray pipe 14 through a water supply line after performing a certain water purification process.

On the other hand, as is apparent from FIG. 1, the drive system housing sections 20 and 21 and the washing section 22 are partitioned in a substantially sealed state by waterproof partition plates 23 and 24. With such a partition structure, it is possible to prevent wear dust and dust generated from gears or wear parts of the drive system from being mixed into the drainage of the cleaning liquid to be reused. The drive system housing section 21 houses a drive system (not shown) for driving the upper spray pipes 13 and 14.

[00010]

As described above, according to the present invention, a driving system for driving a transport roller for transporting a glass substrate,
By providing a sealing partition between the area where the glass substrate is cleaned (cleaning section), the drive system storage section and the cleaning section are completely separated, and the wastewater after cleaning is reused. Dust generated from the drive system, especially wear dust generated by the engagement of the drive gear is not mixed into the drainage,
The degree of maintenance or replacement of the circulation filter can be extremely reduced. However, the liquid crystal cell manufacturing process can be performed more efficiently than before, and the product yield is improved.
