A kind of polishing jig and polishing method

Abstract

The invention discloses a polishing tool. The polishing tool comprises a main body and a protecting pad; the main body is provided with a groove; the protecting pad is arranged in the groove, and is used for placing pieces to be polished; an ejecting block is arranged between the protecting pad and the bottom of the groove, is arranged deviated from the center of the groove, and is used for movingat the bottom of the groove to adjust the inclined direction of the protecting pad; a vacuum channel is formed in the bottom of the main body; and the vacuum channel communicates with the groove, andis connected with a vacuum source. The protecting pad can improve the problem of easy scratch caused by bad contact between the pieces to be polished and the polishing tool, meanwhile, can incline the pieces to be polished in any direction to achieve excellent polishing of the edges of the pieces to be polished. The invention further discloses a polishing method adopting the polishing tool; the ejecting block is adjusted to two different positions; higher points of bridge surface glass are polished; and the convex surface flat polishing and the plane flat polishing are performed on the bridgesurface glass.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing technology, in particular to a polishing jig and a polishing method. Background technique [0002] With the development of science and technology and the improvement of people's living standards, electronic products such as mobile phones, tablet computers and watches have become indispensable consumer products for people. [0003] When producing bridge-shaped watch covers, the bridge-shaped watch covers need to be polished to improve perspective, strength and aesthetics. The current polishing method is to directly use flat polishing equipment to polish the bridge-shaped glass. Some manufacturers use programming to design the polishing track and use automation to polish the bridge-shaped glass. [0004] Due to the special structure of the bridge glass, the polishing effect in the prior art is poor, which may easily lead to the collapse of the higher surface in the middle, and chipping ...

AI Technical Summary

Problems solved by technology

[0004] Due to the special structure of the bridge glass, the polishing effect in the prior art is poor, and it is easy to cause the high surface in the middle to collapse, and the edge of the product to collapse, resulting in low product yield.

However, the use of programming to design the polishing trajectory greatly increases the cost of the equipment.
