Problems solved by technology

[0004] However, due to the difference in thermal expansion coefficient between the three-dimensional glass product and the fixture, the glass will be released from the mold after the temperature difference in real time. Without a good design of the relationship between the thermal expansion coefficient of the three-dimensional glass product and the fixture, there will still be glass sticking situation arises

Embodiment 1

[0028] See Figure 1A to Figure 1C , Is the production flow chart of the three-dimensional glass of the first embodiment of the present invention.

[0029] First, like Figure 1A As shown, a first mold core 31, a second mold core 32 and a glass substrate 1 are provided in the cavity of a heating furnace 2 having a heater 21 and a conveyor belt 22, and the glass substrate 1 has A first molding surface 11 and a second molding surface 12 opposite to the first molding surface 11; the glass substrate 1 is set above the second mold core 32, and the second mold core 32 can be moved to by the conveyor 22 Corresponds to the position of the first mold core 31. In addition, the second mold core 32 has a concave structure, and the first mold core 31 has a convex structure, and it is connected to the heating furnace 2 by a connecting handle (not shown), and is vertically arranged in the furnace cavity of the heating furnace 2.

[0030] Then, like Figure 1B As shown, the cavity 2 of the heatin...

Embodiment 2

[0035] See image 3 , Is a schematic diagram of the production of three-dimensional glass in the second embodiment of the present invention. by image 3 As shown, this embodiment is a two-stage heating. A preheating furnace 5 and a forming furnace 6 are provided on a conveyor belt 8. First, a second mold core 72 and a glass substrate 4 are provided, and the glass substrate 4 It has a first molding surface 41 and a second molding surface 42 opposite to the first molding surface 41; the glass substrate 41 is placed above the second mold core 72, and the second mold core 72 can be moved by the conveyor belt 8 To the required location. In addition, the second mold core 72 has a concave structure.

[0036] In this embodiment, the furnace cavity of the preheating furnace 5 includes a heater 51 and a ventilation / exhaust pipe 52; in addition, the heater 51 of the preheating furnace 5 is a resistance-type wire heater, which allows the glass substrate 4 to perform The temperature is rais...

Abstract

The invention provides three-dimensional glass and a method for manufacturing the same. The method for manufacturing the three-dimensional glass comprises: (a) providing a first insert, a second insert and a glass substrate in a cavity of a heating furnace; (b) heating until the temperature of the heating furnace exceeds the softening temperature of the glass substrate, and applying weight of the first insert onto the glass substrate, so as that the glass substrate is relatively abutted against the second insert to form the three-dimensional glass, wherein the coefficient of thermal expansion of the glass substrate is between that of the first insert and that of the second insert; and (c) quenching and annealing the glass substrate. Therefore, the method solves the problem of adhesion between the glass substrate and the insert in a demolding stage, and effectively raises quality and flatness of the glass substrate moulding.

Description

Technical field [0001] The invention relates to a three-dimensional glass and a manufacturing method thereof, in particular to a method suitable for manufacturing three-dimensional glass and three-dimensional glass used in electronic products. Background technique [0002] In recent years, high-quality optical glass lenses are required for digital cameras, digital cameras and smart phones. In addition, thin glass sheets have recently been widely used in liquid crystal displays, organic light emitting semiconductor (OLED) displays, or various touch panels. With the development of science and technology, the requirements for products are getting higher and higher. At the same time as the pursuit of lightness and thinness, the quality requirements are also indispensable. Therefore, while the thin glass sheet is shaped, the quality requirements are also very important. of. [0003] Taiwan Bulletin No. M406042 discloses a three-dimensional glass shell jig and an electronic product wit...
