Description

Glass reinforcement fixture

Technical Field

The invention belongs to the field of ultrathin glass clamping, and particularly relates to a glass reinforcement clamp.

Background

Ultrathin glass is also called ultrathin electronic touch glass, and generally refers to glass with the thickness of 0.1-1.5 mm. Liquid crystal displays in the electronic information industry commonly use 0.55-1.1mm float ultra-thin glass. The thinner the glass, the better the light transmission performance, the better the flexibility and the weight reduction. The folding smart phone is mainly applied to folding smart phones, flexible display screens and the like.

With the reduction of the thickness of the glass, the surface of the glass is easy to generate fine scratches and break in the use process, so that the ultra-thin glass needs to be strengthened.

In the prior art, the patent number 2021113989680 discloses two technologies, namely, a groove strip is used for forming linear supports on the upper end and the lower end of glass, and in the process of normal-temperature cooling after high-temperature strengthening, stress unevenness can occur at the contact place of the glass and the groove strip and the place not contacted with the groove strip due to different material properties and cooling and radiating speeds of the groove strip and the glass, so that the glass is cracked or strength is reduced. In order to solve the problem of uneven cooling, the method for clamping the glass in a point contact mode by using the crossed ropes is proposed, and the uneven stress of the part, which is contacted with the crossed ropes, on the glass is weakened to a certain extent due to the reduction of the contact area of clamping fixation, so that the yield of the glass is improved. However, the contact point itself has a large force on the glass, and stress concentration often occurs due to the large force at the contact point.

The invention combines the two technical characteristics to solve the problems of uneven cooling and stress concentration of the supporting points.
