an aeration device

Abstract

The invention discloses an aerating device which comprises an aerating disc face and an air outlet unit. The aerating disc face comprises a plurality of aerating pipes arranged in parallel, the pipe wall of each aerating pipe is provided with a plurality of air outlets, an air outlet unit is arranged inside each air outlet, each air outlet unit comprises a base, a porous permeable pipe, an air collecting box and a sealing cap which are arranged in sequence, wherein the porous permeable pipe, the air collecting box and the sealing cap are fixed to the base. By arranging the air outlet units inside the air outlets, the single-hole air outlet adopted in the prior art is changed into the porous air outlet units, and the defects that a traditional aeration mode is short in service cycle, poor in production stability, high in maintenance cost and the like are overcome structurally.

Description

technical field [0001] The invention relates to the field of liquid crystal panel manufacture, and particularly designs an aeration device. Background technique [0002] The current society has entered the era of informationization and digitalization. TFT-LCD panel display technology has been widely used in daily life, especially the requirements for thin and light mobile terminals are increasing day by day. Emerging consumer electronic products such as smart phones and tablet computers Transforming to ultra-thin, the display screen is often only 0.3mm-0.5mm thick. At present, it is difficult for high-generation TFT equipment production lines to process substrate glass below 0.3mm, and the yield and cost are greatly limited. Traditional array substrates And the color film substrate is generally about 0.4mm-0.6mm, plus the liquid crystal and other materials filled in the middle, the thickness after lamination generally reaches about 0.8mm-1.0mm, the most economical and afford...

AI Technical Summary

Problems solved by technology

However, as the thinning process proceeds, the etching solution and the main component of glass, SiO 2 The fluorosilicate produced after the reaction will deposit on the aeration tube, which will cause the blockage of the air outlet, the effect of bubble stirring will be reduced, the glass raw material will be etched unevenly, and even the glass substrate will be broken

Therefore, the traditional aeration method has the disadvantages of short service life, poor production stability and high maintenance cost.
