Description

Technical Field

[0001] The utility model belongs to the technical field of glass, and specifically relates to a novel throwing and tempering device for ultra-thin flexible glass. Background Art

[0002] With the replacement of electronic products, glass has been widely used in the electronics industry. The market requires the thickness of touch screen glass cover protective glass to be thinner and thinner. Ultra-thin glass has become one of the important development trends of glass. Ultra-thin glass cover has attracted more and more attention from listed companies in the electronic display industry. It is mainly used in folding mobile phones, folding laptops and various wearable electronic devices. Ultra-thin glass (UTG) refers to glass with a thickness of less than 100μm and is flexible. UTG is widely used in various electronics industries due to its high transparency, stability and impact resistance. Its easy-to-bend characteristics have marked a major milestone for the folding display industry, becoming an important player in the field of foldable flexible cover after CPI cover.

[0003] The patent number is 202120002708.6, and the disclosure date is September 28, 2021. In a public specification, a tooling for tempering ultra-thin flexible glass (UTG) is disclosed, including: a mounting frame, which is formed by connecting multiple support surfaces end to end; a support bar, which is detachably installed in the mounting frame, and a plurality of the support bars are arranged in a horizontal and vertical interval to form an independent chamber for storage. The tooling is placed in a tempering furnace to temper the glass. The mounting frame and the support bar are made of high-temperature resistant materials. The support bar is detachably installed in the mounting frame. A plurality of the support bars are arranged in a horizontal and vertical interval to form an independent chamber for storage. The size of the independent chamber is still determined by the size of the foldable glass. When it is necessary to temper glass similar to the size of a mobile phone screen, the horizontal and vertical intervals between the plurality of the support bars are relatively small. When it is necessary to temper glass similar to the size of a tablet screen, the horizontal and vertical intervals between the plurality of the support bars are relatively large.

[0004] Currently, in the field of foldable screen mobile phones, ultra-thin flexible foldable glass is usually used as the auxiliary cover of the mobile phone's outer screen. Ultra-thin flexible glass needs to have certain strength, feel, and excellent optical and bending properties. However, based on the existing processing technology of domestic glass manufacturers, ultra-thin flexible glass cannot be prepared in one go, and usually involves secondary thinning, tempering and other processes, especially glass tempering. For folding glass, the tempering process is very important, because the ultra-thin glass to be tempered itself has a certain flexibility. Based on the field of use of ultra-thin flexible glass and the characteristics it needs to have, the method we usually use to temper ultra-thin flexible glass is the low-temperature ion exchange method, and the glass is placed in a molten alkali salt solution, and the ion exchange method is used. Increase the strength of the glass, but if you want the folding glass to have better bending performance, the thickness of the glass itself cannot be ignored. Usually the thickness of the folding glass is usually between 30μm and 50μm, because the thinness of the glass means that the glass itself has a certain flexibility. The thinner the glass, the higher the upper limit of its bending. On the contrary, the thinner the glass is, the thinner it is, the more stringent the requirements for the environment, process, and operating methods will be during actual processing, especially in the tempering process. Tempering involves ion replacement, which is a micro-change process. When the glass itself is thin, the glass will be easily affected during the tempering process, and this influence will be highlighted and amplified due to the thinner thickness. The following table shows the apparent data of 30μm thick glass after tempering for 36 minutes.

[0005]

[0006] According to the appearance conditions in the form, when the glass is thin, the appearance problems after tempering will be very serious, and there will be a variety of appearance problems. The fundamental reason is that when the glass is put into the tempering process, a variety of dust impurities will adhere to the surface. When it is put into tempering, some impurities with poor adhesion will continue to remain in the tempering liquid, and some impurities with strong adhesion will always remain on the glass surface during tempering. This will cause uneven replacement of the impurity attachment points during tempering, but when uneven replacement occurs, tempering marks will easily appear. Utility Model Content
