Embodiment Construction

[0044] figure 1 Flowchart of the glass thinning process performed for the prior art. As shown in the figure, the existing technology is to coat the surface that does not need to be etched with a mask as a protective layer before the glass substrate is chemically thinned and etched, and then support the transportation of both ends of the glass substrate from the left and right of the glass transportation direction. The roller realizes the clamping of the glass substrate so as to complete the thinning process (as described in the patent of CN1669967A), and its manufacturing process is as followsfigure 1 As shown, the disadvantage of this technology is that it adds a lot of extra operations other than thinning, which leads to an increase in cost, such as: adding protective layer coating, drying, and removal processes, increasing raw material costs and manufacturing processes , which increases the difficulty of controlling the yield rate and reduces production efficiency; increase...

Abstract

The invention relates to a device for bearing transparent conductive film glass during thinning single surface and a thinning method for the transparent conductive film glass. The device comprises a sealed vacuum chuck 1 totally covering the conductive film surface of plane glass 4 and adsorbing the plane glass 4; an enclosed air suction duct 1c and a vacuum buffer cavity 1f communicated with theair suction duct are arranged in the vacuum chuck 1; and through an enclosed cavity formed by the air suction duct 1c and the vacuum buffer cavity 1f, the plane glass 4 is always adsorbed in the whole thinning etching flow by maintaining the vacuum degree between the vacuum chuck 1 and the plane glass 4 under the condition of cutting off an external vacuum pump source. In the process of thinning the plane glass borne by the device, one surface of the plane glass is not provided with any shield so as to facilitate thinning treatment, and the enclosed surface of the plane glass can ensure the transparent conductive film is protected from the corrosion of chemical solution, so that the process of thinning the single surface of the transparent conductive film glass is greatly simplified and the cost is reduced.

Description

technical field [0001] The invention relates to a glass substrate carrying device and a thinning method thereof, more specifically, to a carrying device for one-sided thinning of transparent conductive film glass and a method for carrying conductive film glass on the device for single-sided thinning. Background technique [0002] Transparent conductive film glass is the main material for the manufacture of flat panel displays (FPDs), and is widely used in liquid crystal displays (LCDs), plasma display screens (PDPs), touch screens (TPs), organic light emitting displays (OLEDs) and other fields. With the rapid development of high-tech products in today's world, the requirements for thinner and lighter FPD panels are getting higher and higher. Therefore, the thinning process of transparent conductive film glass has become one of the core issues of whether terminal display products can be thinned. [0003] The so-called thinning is to uniformly etch the glass substrate of the t...
