Embodiment 1

[0062] Such as Figure 1-5 As shown, this embodiment is a double-bridge glass polishing fixture, and its structure includes: a curved glass placement carrier 10 , a carrier plate 20 and an outer ring gear 30 . The double-bridge glass in this embodiment is bracelet glass, including the highest end surface and two special-shaped end surfaces R surfaces.

[0063] Wherein, the specific structure of the curved glass placement carrier 10 is as follows: figure 1 As shown, it includes a cavity 11 for placing the bracelet glass. The shape of the bottom support surface in the cavity 11 matches the shape of the curved glass to be processed, and the depth from the opening of the cavity to the bottom support surface is 0.1mm smaller than the thickness of the curved glass to be processed.

[0064] In this embodiment, the length and width of the curved glass placement carrier 10 are 100 mm and 70 mm respectively, and the depth from the opening of the cavity to the bottom support surface is...

Embodiment 2

[0072] This embodiment is a method for polishing curved glass. The polishing jig provided in Embodiment 1 is used to polish the ring glass. The specific steps include:

[0073] Step a): Install the brush plate on the flat grinder, and adjust the ratio of 3D polishing liquid;

[0074] Among them, the brush disc is made of 73-degree polished leather and white or gray nylon filament in a ratio of 1:1, 2:1 or 1:2; the 3D polishing liquid is a mixture of cerium oxide with a particle size of 0.3-1.5 microns , the concentration is 1.15g / ml;

[0075] Step b): Install the sintered and molded wristband glass with its front facing up in the curved glass placement carrier. A layer of black cushion with adhesive backing is attached to the curved glass placement carrier, and the black cushion is fixed on the bottom support surface;

[0076] Step c): Install the curved glass carrier in the groove of the bearing plate, fix the bearing plate and the outer ring gear, install the outer ring gea...

Abstract

The invention provides a curved glass polishing clamp and method, and a polishing device, and relates to the field of machining of curved glass. The curved glass polishing clamp comprises a bearing disc, a groove used for accommodating the curved glass is formed in the bearing face of the bearing disc, and the bearing face is a bevel. By utilizing the polishing clamp, the problems that in the prior art, when a polishing clamp or a polishing machine polishes double-bridge glass, the technical problems of thin meat and local collapse are caused, and the production efficiency is low due to a special-shaped polishing process can be relieved, and the technical effects of improving the production efficiency and improving the polishing quality are achieved.

Description

technical field [0001] The invention relates to the field of processing curved glass, in particular to a curved glass polishing fixture, a polishing method and a polishing device. Background technique [0002] With the development of wearable electronic devices, the application of curved glass is becoming wider and wider, especially the double-bridge glass, which is favored by the market. For example, glass for watch phone or bracelet phone is a kind of double bridge glass. [0003] During the processing of double-bridge glass, when polishing, the original double-bridge glass front polishing method is to place the double-bridge glass flat in the fixture and process it through a polishing process. When placed flat, due to the height difference between the two ends of the double-bridge glass and the middle part, when polishing, the curved surfaces at both ends of the front of the double-bridge glass cannot be polished or the polishing force is too small, resulting in poor pen...
