Description
The technical field is as follows:
the utility model relates to a TFT-LCD glass substrate's production facility field, specifically speaking are exactly a glass substrate cutting lobe of a leaf dust remove device.
Background art: the TFT-LCD glass substrate is alkali-free borosilicate glass, the glass characteristic of the TFT-LCD glass substrate is harder than that of common glass, and more dust is generated in the cutting and splitting processes and is easy to adhere to the surface of the glass substrate to form the adhesion defect of glass powder; for example, the glass dust is vibrated in the processing process, which can cause scratch defects of the glass substrate; during the transportation process, the glass substrate is in contact with other adjacent glass substrates, and the other glass substrates are scratched. The production of the liquid crystal display screen needs to evaporate circuits on a TFT-LCD glass substrate, and the adhesion of glass dust can cause the disconnection of the display screen, thereby causing the defects of bright spots, bright lines and the like. To avoid this, it is important to eliminate glass substrate cutting dust.
The ribbon of glass exiting the lehr during the scoring and breaking of the glass substrate is gradually cooled to a maximum of about 80 c to cut the ribbon to the desired glass size. The cutting knife wheel perpendicular to the air surface of the glass ribbon marks the glass substrate, and glass dust is generated in the marking process.
The glass sheet breaking process is a composite process, the glass sheet is broken off and separated from the glass ribbon, the two actions are completed instantly, the chopping block gives an upward force to the tin surface of the glass ribbon through the air cylinder, and when the glass ribbon is jacked to the pressing plate strip, the pressing plate strip gives a downward force to the glass ribbon to separate the glass sheet from the glass ribbon. A large amount of glass dust can be generated in the process, and the glass dust needs to be eliminated in time due to the fact that the temperature of the glass sheet is high and the adhesion capability is strong.
Through online and offline detector detection, the dust condition of the glass before cutting and splitting is detected:
the generation of dust on the surface of the glass substrate is analyzed from data, after the glass substrate is longitudinally cut, certain glass dust is adhered to the air surface of the glass substrate, and the tin surface has no glass dust.
After the splinter, the glass dust on the air surface is increased, and the glass dust is generated on the tin surface.
The rear section is cleaned and blown to remove glass dust;
because the glass area temperature is higher, the glass dust adhesion is at glass piece air side, tin face, carries out abluent in-process at the back end, because the absorption of water, the adhesion reinforcing between glass bits and the glass can not get rid of the glass dust, and adopts the deionized wind to blow to the glass surface, can effectively get rid of the dust on glass surface.
And set up static blast apparatus like patent No. 201420644364.9 at the mounting structure top among the prior art, but do not have the device that induced drafts, cause the glass dust to fly everywhere easily, cause the pollution to the glass substrate once more. (2) The patent No. 201310272929.5 sets a dust hood in the range of matching the length of the marking line; in the splitting step, before the glass substrate is broken off, an air extractor is arranged on the surface of the glass substrate towards the direction of the anvil strip, and the air flow enters the dust hood.
When the float TFT-LCD glass substrate sheet is cut, the glass temperature is higher to 80 ℃, the adhesion capacity of dust and glass scraps is strong at the temperature, and an air extractor and a dust hood are not arranged on the back surface of the glass, so that the glass scraps generated on the back surface of the glass are lack of cleaning capacity, and the dust and the glass scraps cannot be completely removed.
