Embodiment Construction

[0023] The technical scheme of the present invention draws on the process methods of ordinary glass cleaning and glass pattern engraving. By adopting the method of using a circulating etching liquid in the etching tank to perform etching and a matching etching device, the glass substrate is etched, so that the thinned glass substrate is Meet the technical requirements of thin glass substrates for flat display.

[0024] As shown in FIG. 1, it is a schematic flowchart of Embodiment 1 of the thinning method of a flat glass substrate of the present invention. Including the following steps:

[0025] Step 101: Mixing and temperature treatment of the etching solution in the agent proportioning tank;

[0026] Step 102, the etching bath is quickly drawn into the etching solution;

[0027] Step 103: The glass substrate is put into the etching tank, and the etching solution adopts a bubbling method and a self-circulation method to etch the glass substrate;

[0028] Put the glass substrate in...

Abstract

The invention relates to a method for thinning a flat glass substrate and a device thereof. First, etching liquor is mixed and processed of temperature treatment in a reagent preparation trough; the prepared etching liquor is quickly pumped into an etching trough. The glass substrate is placed into the etching trough and is etched by adopting a self-circulation way of bubbling and etching. After being etched, the glass substrate is taken out and the etching liquor is quickly poured into a temporary storage trough for a temporary storage and a precipitation. The etching liquor can be re-prepared and reused when the glass substrate is etched next time. The etched and thinned glass substrate is cleaned, dried and polished. The invention provides the method for thinning the flat glass substrate and a device thereof. By adopting the etching method of reagent circulation and bubbling, the aim of batch production can be received, thus supplying a thin glass substrate product and improving the good product rate and production quantity.

Description

Technical field [0001] The invention relates to a thinning technology of a glass substrate for a flat panel display, in particular to a thinning method and device for a flat glass substrate. Background technique [0002] With the development of flat-panel display technology, thin flat-panel displays have quickly become the mainstream of technology and market development. Flat-panel displays include liquid crystal displays (LCD), plasma displays (PDP), organic electroluminescence displays (OLED), and so on. Among these flat-panel displays, the glass substrate for display is the core component, and its thinning is the core technology for achieving thinner flat-panel display products. [0003] At present, the thinnest glass substrate of flat-panel displays can only be 0.5mm, and the thickness of the glass substrate required by flat-panel display products has reached 0.3mm or even thinner, which has led to the glass substrate thinning technology. The prior art mainly uses physical or...
