Support mechanism for machining double-sided ITO (Indium Tin Oxide) glass

Abstract

The invention discloses a support mechanism for machining double-sided ITO (Indium Tin Oxide) glass, and ensures the surface flatness of the double-sided ITO glass within a certain area. The support mechanism comprises a positioning mechanism and a support mechanism, wherein the positioning mechanism is used for limiting the position of the double-sided ITO glass; the support mechanism is used for supporting the double-sided ITO glass, used for reducing the droop of the double-sided ITO glass, and used for ensuring the machining precision. Because of the large size and small thickness, a small allowable support area is available when ITO glass is machined, and because of the self-gravity, great droop can be resulted, and as a laser process requires that the flatness of the glass surface shall be within a certain range, such as being less than 0.1mm, when the glass is etched by using laser, a support device is essential for ensuring the flatness of the glass when being machined. By adopting the support mechanism of the double-sided ITO glass disclosed by the invention, the problem that the double-sided ITO glass drops down because of the self-gravity in the machining process is well solved, the machining precision is ensured, and the production efficiency and the yield are improved.

Description

[0001] technical field [0002] The invention relates to the field of mechanical processing, in particular to a double-sided ITO glass processing mechanism. [0003] Background technique [0004] ITO is the English abbreviation of indium tin oxide. It is a transparent conductor, usually only a few thousand angstroms thick. Among all transparent conductors, it has excellent physical properties: high visible light transmittance, high Infrared reflectivity, good mechanical strength and chemical stability, can easily form a certain electrode pattern with wet etching process such as acid solution, and the preparation is relatively easy, which makes it widely used in various electronic and optoelectronic devices, Such as flat panel display fields such as mobile phones and computers. Classified by size, common double-sided ITO glass has specifications such as 14*14 inches, 14*16 inches, 20*24 inches, etc. According to thickness, there are 1.1mm, 0.7mm, 0.55mm, 0.4mm, 0.3mm and ot...

AI Technical Summary

Problems solved by technology

Due to the large size and thin thickness of ITO glass, the allowable support area during processing is small, and the glass will sag a lot due to the influence of its own weight. When laser etching glass is used, the laser process requires that the flatness of the glass surface must be Smaller than 0.1mm, so the support mechanism must be used to ensure the flatness of the glass during processing, otherwise it is difficult to ensure the processing accuracy of large-area double-sided ITO glass
