Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, the sapphire window fitting 2 is in the shape of an annular sheet, and the processing method comprises the following steps:

[0028] a. Pretreatment: cutting the sapphire crystal ingot into a sheet-shaped sapphire substrate 1; in step a, first put the block-shaped sapphire crystal ingot into a wire cutting machine for wire cutting, and cut the sapphire crystal ingot into flakes by wire cutting the sapphire substrate 1; put the roughly machined sapphire substrate 1 into the grinder, chamfer the edge of the sapphire substrate 1 with a diamond cutter, and finely grind the outer contour of the chamfered sapphire substrate 1 with a diamond cutter. The cutting fluid is injected during the fine grinding process, and the temperature is maintained at 30°C-60°C by continuously injecting the cutting fluid. The use of wire cutting for blank processing can make full use of the advantages of low processing cost and fast processing speed of w...

Embodiment 2

[0036]The general content of this embodiment is the same as that of Embodiment 1, except that in this embodiment, in step b, the sapphire substrate 1 is first covered with printing paper, and a ring-shaped annular groove is pre-cut on the printing paper. Sapphire ink is brushed on the printing paper, and the sapphire ink passes through the annular groove and is printed on the sapphire substrate 1 . The printing paper can be used repeatedly, and the annular groove can accurately print the corresponding annular ink ribbon 3 on the sapphire substrate 1 with high precision.

Abstract

The invention provides a machining method for a sapphire window accessory of an electronic product, and belongs to the technical field of electronic product screen machining. The technical problem that existing sapphire window accessories are machined by a tool one by one, and the machining efficiency is low is solved. The machining method for the sapphire window accessory of the electronic product comprises the steps that a sapphire crystal block is cut into a sapphire substrate, sapphire printing ink is used for printing a plurality of annular printing ink belts on the sapphire substrate, the printing ink is dried, then the sapphire substrate is placed in a clamp to be fixed, laser light is used for cutting the sapphire substrate into a plurality of annular sheet sapphire window accessories, finally, unqualified products are removed, and qualified finished products are taken out. According to the machining method, due to the fact that the multiple annular printing ink belts are printed on the sapphire substrate through the sapphire printing ink, a plurality of finished products can be obtained through cutting at a time, the production efficiency is improved, laser light can achieve closed-loop control, the laser cutting precision can be improved, and the finished product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of screen processing of electronic products, and relates to a processing method for sapphire window fittings of electronic products. Background technique [0002] With the rapid development of science and technology, touch screens are widely used in electronic products such as mobile phones, handheld computers, car navigators, and notebook computers. Compared with ordinary glass, sapphire crystal has excellent optical properties, mechanical properties and chemical properties. Stability, high strength, high hardness, erosion resistance, and can work under harsh conditions close to 2000 degrees high temperature, so it is widely used in infrared military devices, satellite space technology high-intensity laser window materials, its unique crystal structure, Excellent mechanical properties and good thermal properties make sapphire crystals the most ideal substrate materials for semiconductor light-emitting diode...
