Processing method of 3D glass cover plate

Abstract

The invention provides a processing method of a 3D glass cover plate. The processing method of the 3D glass cover plate comprises the following steps: step 11, material cutting: cutting a large glassplate into a plurality of glass plates with preset sizes; and step 12, CNC: placing the glass plate on a vertical platform in a CNC fine engraving machine for cambered surface processing. The verticalplatform comprises a support plate and a fixing plate vertically connected with the support plate; the support plate is provided with an air suction base, and the air suction base is detachably connected with the fixing plate; the air suction base is parallel to the fixing plate, and is used for adsorbing the glass plate; the glass plate and the air suction base are arranged in parallel, and arcsurface processing is carried out on the glass plate through a processing tool according to a preset arc surface processing line; the processing tool comprises a mounting head and a processing columnconnected with the mounting head; and the processing column is cylindrical, and the surface of the processing column is in contact with the glass plate. The processing efficiency can be improved, andthe problem of obvious tool path marks is solved.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing technology, in particular to a processing method for a 3D glass cover plate. Background technique [0002] With the development of science and technology and the improvement of people's living standards, smart terminals represented by mobile phones and tablet computers have become indispensable consumer electronic products for people. At the same time, people's requirements for such electronic products are getting higher and higher. Taking mobile phones as an example, the cover glass of mobile phones has gradually developed from traditional flat cover plates to 2.5D glass, and now to 3D glass. [0003] 3D curved glass has excellent visual appearance and touch, and has been sought after by people; at the same time, with the promotion of 5G signals, the 3D glass cover can meet the perfect combination of 5G signals, wireless charging and OLED, so 3D curved glass has become the future of m...

Problems solved by technology

However, in the existing technology, the CNC processing method of the horizontal plane is generally used, which is inconvenient to process, requires multiple processing, long production time, low efficiency, and needs to cooperate with the ball-end cutter to produce the arc surface, the surface effect is rough, and the tool path imprint is obvious , it is difficult to remove when sweeping, which affects the appearance of the product
