Problems solved by technology

The existing observation method is to use a laser pointer to directly irradiate the outer surface of the sapphire crystal to observe, and the laser light will be reflected on the outer surface of the sapphire crystal. Since there is strong reflection when the laser pointer is directly irradiated on the outer surface of the sapphire crystal, the existing The observation and sorting method will not only hurt people's eyes, but also affect the observation effect, which is not good

Abstract

A device for observing and sorting sapphire crystal bubbles comprises a high transparent glass container containing purified water, a hoisting pulley, a fastening rope and a support frame. The support frame is arranged below the high transparent glass container, a support spigot hole is arranged at the center of a support face plate of the support frame, the outer diameter of the support spigot hole corresponds to the outer diameter of the high transparent glass container, the inner diameter of the support spigot hole corresponds to the diameter of an inner cavity of the high transparent glass container, the hoisting pulley is located above the high transparent glass container, the fastening rope is wound on the hoisting pulley, one end of the fastening rope ties a sapphire crystal block, and the other end of the fastening rope is fixed. When a user uses a laser pen for performing laser irradiation on the surface of a crystal, laser penetrates through the wall of the high transparent glass container and the purified water and then irradiates the sapphire crystal. The device is used for observing and sorting the sapphire crystal through reflection and refraction, facilitates good observation and sorting for the user, can perform 360-degree full-angle observation on buttons in the sapphire crystal, and cannot hurt eyes of the user.

Description

Technical field: [0001] The invention relates to a crystal observation device, in particular to a bubble observation and sorting device in a sapphire crystal. technical background: [0002] Sapphire (sapphire) is Al 2 o 3 Single crystal, with high melting point (about 2050 ℃), high hardness, good thermal conductivity, wide light transmission band, good electrical insulation, strong acid and alkali corrosion resistance, etc. Currently producing large size Al 2 o 3 The methods of single crystal include kyropoulos method, pulling method, heat exchange method and flame fusion method, among which the most widely used and the most mature production technology is the kyropoulos method, but bubbles are also easily generated in the obtained sapphire single crystal, which greatly Large bubbles will form millimeter-scale cavities, and small bubbles will appear as a large number of cloud-like scattering particles. Whether there are bubbles in the sapphire crystal or not, the size of...
