Technological process of 3D glass lens

Abstract

The invention discloses a technological process of a 3D glass lens. The technological process comprises the steps of removing ink from the glass lens; S2, cleaning the glass lens, and inserting the reinforced glass lens into a standard tempering frame; S3, preheating a preheating furnace, and putting the inserted and erected glass into the preheating furnace when the temperature of the preheatingfurnace rises to 380 DEG C, wherein the preheating time is 1 hour; S4, transferring the preheated glass lens into a liquid medicine furnace to be subjected to stress relief, wherein the temperature ofa liquid medicine solution in the liquid medicine furnace is 420 DEG C, placing the preheated glass lens into the liquid medicine furnace, and conducting ion exchange in a closed container for 6-8 hours; S5, transferring into a cooling furnace, and transferring the glass into a circulating water tank for soaking and cleaning after the temperature of the product is reduced to room temperature; S6,sweeping a concave surface and a convex surface of the glass lens; and S7, putting the glass lens into the furnace for secondary strengthening. According to the invention, the hardness of the glass is enhanced, the service life of the glass is prolonged, the cost is greatly saved, defective products can be repaired, and the input and output are improved while the repairing performance is ensured.

Description

technical field [0001] The invention relates to the technical field of glass lens technology, in particular to a process flow of a 3D glass lens. Background technique [0002] 3D glass generally refers to glass with a larger screen curvature. It has the advantages of being thin, transparent and clean, anti-fingerprint, anti-glare, hard, scratch-resistant, and good weather resistance. Compared with 2D glass and 2.5D glass, it is safer. , Longer service life, but also more in line with the aesthetics of consumers. In recent years, due to the wide application of flexible OLED screens, bendable 3D glass has become the first choice. The 3D glass cover plate cooperates with OLED screens to achieve higher image clarity. With the further popularization of intelligent curved screens, the demand for 3D glass will increase day by day. It is estimated that in 2020, the demand for 3D glass cover plates will reach 1.147 billion pieces. [0003] The existing 3D glass will produce defecti...

Problems solved by technology

[0003] The existing 3D glass will produce defective products during production. Generally, the defective products produced by the factory cannot be used and can only be regarded as defective products, which greatly increases the cost. Moreover, when the glass is tempered, the tempering of each material is generally Salt has a short lifespan and a high cost
