Description

Technical Field

[0001] The present invention relates to the technical field of electronic product screens, and particularly relates to a manufacturing method for an eye-protecting 2.5D glass cover plate. Background Art

[0002] With the continuous development of the technology of electronic products, as one of the components of electronic products, the screen has also developed faster and faster. The components of the screen include a glass cover plate, also known as a glass protection screen, which is made of transparent glass material and has characteristics such as strong light transmittance, high strength, good toughness, and strong abrasion resistance.

[0003] Currently, the requirements for the screen of electronic products are getting higher and higher. The glass cover plate not only changes in shape but also has an eye-protecting function. In terms of shape, it has developed from the initial 2D to 2.5D and even 3D. The 2D glass cover plate is completely flat without any arc design. The middle of the 2.5D glass cover plate is flat, but the edge is arc-shaped. This design not only provides a better edge grip but also maintains the flat display effect of the screen. However, when manufacturing this shape of the glass cover plate, due to the high requirements for gloss and smoothness of the product, especially at the edge, a polishing process is required. Although the polishing process greatly improves the light transmittance of the product, it also reduces the eye-protecting effect of the product. Summary of the Invention

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0019] Refer to Figures 1-3 , the manufacturing method of the eye-protecting 2.5D glass cover plate of the present invention includes the following steps:

[0020] 1) Take a piece of glass. According to the required size requirements, the glass is cut and CNC precision carved into a 2.5D glass cover plate, and the manufactured 2.5D glass cover plate is cleaned.

[0021] 2) The 2.5D glass cover plate obtained in step 1) is subjected to polishing processing in a polishing device. The polishing device includes a base, a telescopic device and a pressing plate. A bracket is arranged above the base, and a polishing mechanism and a telescopic device are arranged on the bracket. The polishing mechanism can also move up and down. The upper end surface of the base is provided with a supporting surface adapted to the surface of the glass cover plate. A positioning groove is arranged outside the edge of the supporting surface. The telescopic device is arranged on the bracket above the base. The output end of the telescopic device faces downward and is connected to the pressing plate. The surface of the pressing plate is adapted to the flat area of the surface of the glass cover plate, that is, the cross-sectional size covers the flat area of the glass cover plate. A soft rubber layer is arranged on the lower surface of the pressing plate to prevent scratching the surface of the glass cover plate. During the polishing process, the glass cover plate is placed on the upper end surface of the base, and the edge of the glass cover plate is stuck in the positioning groove. The telescopic device is started to drive the pressing plate to press down the glass cover plate. A pressure sensor can be arranged on the pressing plate to sense the pressure on the surface of the glass cover plate. The polishing mechanism of the polishing device polishes the edge of the glass cover plate.

[0022] 3) After the processing is completed, the polishing mechanism and the pressing plate are lifted, and the glass cover plate on the base is taken out. Check the situation of the edge of the glass cover plate, such as contour, size, roughness, etc., and clean it, that is, the production of the eye-protecting 2.5D glass cover plate is completed. The cleaning in the production steps is ultrasonic cleaning.

[0023] A sealing ring is arranged on the lower surface of the pressing plate of the polishing device of the present invention near the edge. The sealing ring is arranged outside the soft rubber layer. The soft rubber layer can adopt damping cloth. An air suction channel penetrating to the supporting surface is arranged in the base. The air suction channel is connected to an air suction mechanism. By sucking air through the air suction mechanism, the glass cover plate is adsorbed and closely attached to the supporting surface to prevent movement during the polishing operation. The air suction channel includes a main channel, an air cavity and branch channels. One end of the main channel is connected to the air suction mechanism, and the other end is connected to the air cavity. The transverse cross-sectional area of the air cavity is the same as that of the glass cover plate. A plurality of branch channels are arranged. One end of each branch channel communicates with the air cavity, and the other end leads to the supporting surface. The plurality of branch channels are evenly distributed in the area of the transverse cross-section of the air cavity.

[0024] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present invention, used to illustrate the technical solutions of the present invention, rather than limiting it. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that any person skilled in the technical field of the present invention can still modify the technical solutions described in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be covered by the protection scope of the present invention.
