Description

Glass polishing device

Technical Field

The invention belongs to the technical field of glass processing equipment, and particularly relates to a glass polishing device.

Background

The glass is a non-metallic silicate material, the main component of which is a silicate double salt, is an amorphous solid with a random structure, is widely applied to buildings, is used for isolating wind and transmitting light, and belongs to a mixture. Colored glass in which an oxide or salt of a certain metal is mixed to develop a color, tempered glass produced by a physical or chemical method, and the like are also available. Some transparent plastics, such as polymethylmethacrylate, are sometimes also referred to as plexiglas. Glass products are widely used in various application fields such as architecture, daily use, chemistry, electronics, instruments and the like. With the development of economy, the living standard of people is greatly increased, and particularly in the current stage, more and more people tend to favor the glass products, no matter the household decoration or the building materials, the glass is indispensable in the current stage, and in some applications, such as automobile glass or display screens, large-area flat glass is required to be used. Before assembling these flat glasses, the surfaces of these flat glasses usually need to be polished by large-scale polishing equipment to obtain flat, smooth surfaces.

However, it is still difficult to prevent the plate glass from being scratched during transportation and installation. Scratches on the surface of the plate glass may affect its use. However, large polishing equipment has difficulty in dealing with some local scratches on the glass surface, especially if the glass has been mounted on, for example, an automobile or a display or other application equipment, and some of the glass with excessive surface scratches has to be discarded. This causes unnecessary waste of resources. In recent years, with the development of life needs of people, glass products are not only on the level of plane glass, but various curved glass is widely applied due to unique advantages, but the processing is relatively troublesome, for example, the process of grinding and polishing the curved glass is carried out.

The glass polishing device can only polish glass to be polished in a single shape, can only polish one glass to be polished at a time, and is low in polishing efficiency because the polished glass needs to be taken down from the grinding disc and then installed on the grinding disc for polishing after polishing is finished. In addition, a conventional processing technology generally adopts a handheld polishing machine for grinding, meanwhile, curved glass is more difficult to process than flat glass, and the glass can be ground by careless manual processing. Patent No. cn201811536695.x discloses a curved glass polishing machine, which can polish curved glass, but the contact glass surface per unit time is limited, i.e. small, the polishing efficiency for glass with large volume needs to be improved, and it is not convenient to convert into plane polishing for diversified production processing.
