Problems solved by technology

However, this method has the following problems: the surface of the glass is not uniformly etched, and impurities generated in the etching process adhere to the surface of the glass, making the surface of the glass rough
[0007] However, the etching method using air bubbles has a problem that when the air bubble moves toward the upper end of the etching tank, it joins with the air bubbles around it to become very large, so that a vortex occurs in the etching tank, thereby bending the glass
When the glass is bent due to swirls, the glass may become brittle and it is difficult to etch the glass uniformly

Abstract

The invention relates to a bubble generator for a glass etching device, which is used for generating micro-bubbles to etch glass. The bubble generator comprises a gas inlet pipe, hole sockets and a bubble generation filter, wherein the gas inlet pipe is mounted on the lower part of an etching bath and comprises a plurality of holes which are formed in the outer surface of the gas inlet pipe and used for discharging gas fed into the gas inlet pipe; the hole sockets are fixedly inserted into the holes of the gas inlet pipe, a plurality of fine holes are formed in the hole sockets, and the fine holes are communicated with the holes; the bubble generation filter is linked to the upper surfaces of all the hole sockets and used for generating the bubbles for performing glass etching in the etching bath. The bubble generator uses the bubble generation filter to uniformly generate the micro-bubbles taking micrometers as the unit in the etching bath. Therefore, the problems of the vortex in the etching bath due to increased size of the bubbles caused by bubble combination and the bending of glass caused by the vortex in the prior art can be prevented. In addition, the glass can be stably and uniformly etched through the micro bubbles.

Description

technical field [0001] The present invention relates to a bubble generator for a glass etching device, and more particularly, to a bubble generator for a glass etching device capable of generating fine bubbles for etching glass. Background technique [0002] Various flat panel displays have been studied recently, such as liquid crystal displays (LCDs), plasma display panels (PDPs), electroluminescent displays (ELDs), and vacuum fluorescent displays (VFDs). Among these displays, LCD is most actively researched due to its good image quality and low power consumption, although it has various drawbacks. [0003] Currently in the market, LCDs are used in portable televisions (TVs) and laptops, but there are still many problems to be solved. In particular, since users always carry portable TVs and laptops, reducing the size or weight of LCDs to some extent is considered a key success factor for the development of LCDs. In order to reduce the size or weight of the LCD, various me...
