Abstract
The invention discloses a cleaning technology for ITO glass. The technology comprises the following steps that firstly, the ITO glass is tested through an ohmmeter, the ITO face of the ITO glass is determined, and the ITO glass with the ITO face facing upwards is arranged in a basket; secondly, the basket containing the ITO glass is placed in a first ultrasonic cleaning tank to be subjected to ultrasonic cleaning for 3 min-5 min, and cleaning liquid in the first ultrasonic cleaning tank is cleanser essence cleaning liquid; thirdly, the glass cleaned in the second step is placed in a second ultrasonic cleaning tank to be subjected to ultrasonic cleaning for 2 min-3 min, and cleaning liquid in the second ultrasonic cleaning tank is a sodium hydroxide solution with the PH value ranging from 8 to 10; fourthly, the glass cleaned in the third step is placed in DI water to be subjected to ultrasonic cleaning for 1 min-2 min; fifthly, the glass cleaned in the fourth step is placed in pure isopropyl alcohol liquid to be subjected to ultrasonic water removal for 2 min-3 min; and sixthly, drying is conducted, and water or the solution on the surface of the glass cleaned in the fifth step is removed. No water spots are left on the surface of the ITO glass cleaned through the cleaning technology.
Description
Technical field
The present invention relates to a kind of production technology of LCD, more particularly, to a kind of cleaning of ito glass.
Background technology
Present LCDs are all to be fitted with two pieces of ito glasses, are filled with liquid crystal in the middle of glass.The ITO when producing
Glass is a monoblock, needs ito glass is carried out, and needs to clean very clean, but existing technique is clear
Wash and can be stained with substantial amounts of water on rear ito glass, and in water due to cleaned glass inevitably have water stain, thus affecting
The quality of the LCD producing.
Content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, does not have water after providing a kind of cleaning on glass
The cleaning of the ito glass of stain.
For solving above-mentioned technical problem, technical scheme proposed by the present invention is：A kind of cleaning of ito glass, including
Following steps, 1）Ito glass is tested by ohmmeter, determines the ito surface of ito glass, by ito surface loading basket upwards；
2）The basket that will be equipped with ito glass is put in the first ultrasonic cleaning tank, cleans 3-5 minute with ultrasound wave, described the first surpasses
Cleanout fluid in sound rinse bath is liquid detergent cleanout fluid；
3）The glass that step 2 has been cleaned is put in the second ultrasonic cleaning tank, cleans 2-3 minute with ultrasound wave, described the second surpasses
Cleanout fluid in sound rinse bath is the sodium hydroxide solution of PH=8-10；
4）Glass after step 3 has been cleaned is put into and is cleaned 1-2 minute in DI water with ultrasound wave；
5）The glass that step 4 has been cleaned is put into and is used supersonic dewatering 2-3 minute in pure isopropyl alcohol liquid；In the present invention,
The principle dissolved each other using water and isopropanol, by water dissolution in aqueous isopropanol, such glass would not have water stain residual.
6）It is dried, the water of the glass surface after step 5 is cleaned or solution remove.
The cleaning of above-mentioned ito glass is it is preferred that described step 6 is to use stove-drying.
The cleaning of above-mentioned ito glass is it is preferred that described step 6 is to be done with pure wind.
In the present invention, must assure that ito surface upward during ito glass dress basket, this is because needing to glass when filling basket
Pulled and pushed, if ito surface is down, easily scratched ito glass.Greasy dirt etc. can be cleaned up by liquid detergent in the present invention, ash
Dirt, oils and fatss etc., the alkali liquor of uniform temperature has good cleaning action to ITO glass, and high purity water cleaning can remove and is dissolved in the miscellaneous of water
Matter and some dusts, the alkali liquor that simultaneously can also go up operation is got rid of, and the cleaning action of ultrasound wave, it is to exist using hydrone
There is vibration friction in the presence of ultrasound wave, so that the impurity that glass surface adheres to is loosened and come off.
Specific embodiment
For the ease of understanding the present invention, below in conjunction with preferred embodiment, the present invention is made more comprehensively, meticulously to describe,
