3D glass cover plate, processing method and electronic device

Abstract

The invention discloses a processing method of a 3D glass cover plate. The processing method comprises the following steps: processing a plurality of pieces of glass according to a preset size; processing an inner side surface of each glass into a plane; superimposing a plurality of pieces of glass according to a preset position, and welding the glass to form a 3D glass blank; and processing the outer side wall of the 3D glass blank into a bow-shaped arc surface. By adopting the method, the 3D glass cover plate with a complicated structure can be processed, the process is simple, and the yieldis high. The invention also provides a 3D glass cover plate. The 3D glass cover plate comprises at least three glass assemblies of different sizes, the glass assemblies of different sizes are weldedinto a whole body, other glass assemblies of other sizes except for the glass assembly of the largest size form a fastener group for installation, the upper surface of a cross section of the glass assembly of the largest size is in a bow shape, and the lower surface is a plane. The 3D glass cover plate has a fastener structure design, thereby being convenient in assembling. The invention also provides an electronic device, which comprises the 3D glass cover plate. The use experience is better.

Description

technical field [0001] The invention relates to the technical field of glass panel processing, in particular to a 3D glass cover plate, a processing method and electronic equipment. Background technique [0002] With the improvement of people's demand for the appearance and function of mobile phones, and the maturity of related technologies, more and more electronic products will use 3D glass as the front cover or rear cover. At present, there are mainly two processing methods for 3D glass cover plates on the market. One is hot bending technology, which heats and bends glass raw materials of uniform thickness to soften them, shapes them in a specific mold, and then anneals them to make curved 3D glass; The second is mechanical processing. CNC tools are used to perform boring, milling, grinding and other processing methods on the flat glass to process the entire flat glass into a concave-convex three-dimensional shape to make 3D glass. However, the thermal bending technology...

AI Technical Summary

Problems solved by technology

However, the thermal bending technology can only simply produce a curved surface in terms of mechanism design. The shape design is relatively simple, and the combination with the middle frame mechanism can only use the inner curved surface of the glass. The middle frame must be processed with a curved surface to match the inner curved surface of the glass. The two parts can only be assembled and combined by gluing, and the mechanism design such as positioning and buckle that is convenient for assembly cannot be introduced; while the method of mechanical processing needs to process the inner wall and concave surface of the glass, and its processing technology is complicated. , long processing cycle and low yield
