Cutting device for tabular crystal

Abstract

The invention provides a cutting device for a tabular crystal and relates to the technical field of crystals. According to the cutting device, a movement mechanism is arranged on one side of the upper surface of a stand (26); a clamping mechanism is arranged on a workbench (20) of the movement mechanism and clamps the tabular crystal; two cutting mechanisms are arranged on the other side of the upper surface of the stand at an interval; cutting pieces (19) in the two cutting mechanisms are respectively arranged in cutting slots (37) in the two ends of a tabular crystal on the workbench, and the two cutting pieces synchronously cut the middle part of the tabular crystal from the two ends of the tabular crystal, so that the cutting efficiency is largely improved, and meanwhile, the edge breakage possibility of the tabular crystal in a cutting process is effectively reduced; the utilization ratio of the tabular crystal is greatly improved, and then the production costs are reduced. The cutting device for the tabular crystal has the characteristics of convenience in operation and high production efficiency, and is suitable for large-range popularization and application.

[0002] It is known that, with the rapid development of science and technology today, crystals are widely used, from navigation to aerospace, from microelectronics to optoelectronics, from automatic control to intelligent technology, from computers to communications, from life sciences to medical technology, from civil technology As far as national defense science and technology is concerned, no high-tech can be separated from crystal materials. Different crystals have different abilities, and various artificial crystals are leading the way in modern science and technology. , mechanical properties and chemical stability, its high strength, high hardness, erosion resistance and corrosion resistance, can work under harsh conditions close to 2000 ℃ high temperature, and it also has good thermal conductivity and electrical insulation, the most important is Sapphire also has good light transmission, and is widely used in technical fields such as infrared windows, high-strength optical windows, and medical devices. When sapphire is applied to optical windows, it is necessary to cut the sapphire wafer to achieve the required However, due to the high hardness and brittleness of sapphire, it is very difficult to cut sapphire wafers, and the cutting efficiency is low. For example, the diamond-coated wire is often used to cut sapphire. It needs to be replaced after being worn to a certain extent, and the diamond-coated wire will often break during the cutting process, resulting in high cutting costs and relatively low cutting efficiency, etc.
