Manufacturing equipment for front surface glass of electronic product display

Abstract

The invention discloses a device for manufacturing front surface glass of electronic product display devices. The device is used for manufacturing front surface glass, at least partially having a curved surface shape, of the electronic product display devices. The device comprises an inner pipe and a high-temperature chamber, wherein the inner pipe is in a pipe shape and has a specified length; the inner pipe comprises an inlet part and an outlet part, wherein the inlet part is used for enabling a mould assembly to enter the interior of the inner pipe for carrying out heat treatment, and the outlet part is used for enabling the mould assembly to leave the interior of the inner pipe; the high-temperature chamber is arranged between the inlet part and the outlet part of the inner pipe in a way of covering the inner pipe; the high-temperature chamber is internally provided with a heat source, and the heat source is used for forming a high temperature environment for molding the front surface glass transferred in the inner pipe; the inlet part and the outlet part of the inner part are respectively provided with a nitrogen gas supply mouth, and the nitrogen gas supply mouths are used for continuously supplying nitrogen gas for the inner pipe in a manufacturing process of the device; furthermore, at least one side of the inlet part or the outlet part of the inner pipe adjacent to the high-temperature chamber is provided with an emergency nitrogen gas supply mouth; if the oxygen concentration in the inner pipe rises to a reference value or above, the emergency nitrogen gas supply mouth supplies the nitrogen gas for the inner pipe.

Description

technical field [0001] The present invention relates to a manufacturing device of a front surface glass provided on the front surface of a portable terminal or a display, and more particularly, relates to an apparatus capable of effectively preventing oxidation of the glass in a high-temperature chamber under a high-temperature environment and maintaining a uniform high temperature of the three-dimensional (3D) glass. quality, especially for mass-produced front glass manufacturing plants. Background technique [0002] Currently, in portable terminals including widely used smartphones, glass is provided on the front surface of a display device such as a liquid crystal display (LCD) or a light-emitting diode (LED). Furthermore, since the above-mentioned display device has a touch panel function, it is designed to perform a predetermined function by touching the front glass. Furthermore, in addition to personal terminals such as smartphones and touch panels with setting functi...
