[0024] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention and facilitating its implementation.

[0025] like Figure 1 As shown, the present invention provides a method for double-sided edge molding of ultra-thin flexible glass, comprising the following steps:

[0026] S1, placing the glass substrate on the cavity fixture 6;

[0027] S2, positioning the glass substrate using a positioning member;

[0028] S3, performing chamfering and forming processing on the upper edge and the lower edge of the glass substrate.

[0029] Specifically, the glass substrate is the processed material, the glass substrate is ultra-thin flexible glass, and the cavity fixture 6 is fixed on the processing equipment. Figure 2 As shown, the glass substrate is adsorbed on the cavity fixture 6, and the cavity fixture 6 is provided with a vacuum air hole 4 and an air suction groove 5, and the vacuum air hole 4 and the air suction groove 5 are connected to a vacuum generator. In the above step S2, after the vacuum generator is started, negative pressure is generated in the vacuum air hole 4 and the air suction groove 5, and the glass substrate is adsorbed by the negative pressure to achieve fixation of the glass substrate.

[0030] like Figure 2 As shown, the area of ​​the suction groove 5 is larger than the area of ​​the vacuum air hole 4, a plurality of suction grooves 5 are provided, the vacuum air hole 4 is located at the center of the cavity fixture 6, and all the suction grooves 5 are distributed around the vacuum air hole 4. The negative pressure generated in the vacuum air hole 4 and the suction groove 5 enables the glass substrate to be stably adsorbed on the cavity fixture 6, and the glass substrate is not easy to move, ensuring that the glass substrate can be accurately processed, which helps to improve product quality.

[0031] like Figure 2 As shown, the positioning member is an L-shaped structure, and the positioning member includes a first positioning portion 1 and a second positioning portion 2 connected to each other, the first positioning portion 1 and the second positioning portion 2 are perpendicular to each other, and an air avoidance groove 3 is provided at the connection between the first positioning portion 1 and the second positioning portion 2, and the air avoidance groove 3 is a groove provided at the right-angle corner of the positioning member, which is used to avoid the corner of the glass substrate.

[0032] In the above step S2, when the positioning piece is used to position the glass substrate, the surfaces of the first positioning portion 1 and the second positioning portion 2 are in contact with two perpendicular sides of the glass substrate respectively, and there is a certain distance between the surfaces of the first positioning portion 1 and the second positioning portion 2 and the two perpendicular outer wall surfaces of the cavity fixture 6, so that the position of the glass substrate is accurately positioned.

[0033] In the above step S3, the processing equipment is a precision engraving machine, and the grinding wheel rod is driven by the main shaft of the precision engraving machine to rotate, and the upper and lower edges of the glass substrate are chamfered. Through the set shape milling program, plane processing is performed on the precision engraving machine, and the high-speed rotating main shaft is used to clamp the grinding wheel rod to grind the blank glass substrate to remove the excess, and the glass substrate is chamfered up and down to meet the final shape requirements.

[0034] In the above step S3, the edge shape processing is performed by controlling the lifting of the grinding wheel rod through the spindle, and the shape of the edge of the glass substrate is controlled by the lifting of the spindle. The edge control required by the product is accurate, low energy consumption and high work efficiency. In addition, through vacuum negative pressure adsorption and the lifting of the spindle, the situation of one-sided chamfering of the product is avoided, and the overall shape of the product is guaranteed. The whole device has a high degree of mechanization, low dependence on personnel, avoids complicated processes and operations, is easy to operate, has low operating costs and is easier to achieve mass production.

[0035] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
