Abstract

The invention relates to a device capable of automatically measuring the height of crystal growth powder in a crucible, and belongs to the field of crystal growth. The device is simple to operate andhigh in efficiency, the crucible can be automatically and continuously shaken, the powder is uniform and flat, and the height of the shaken powder is automatically detected. The device comprises a balance ball, a balance body, a crucible, an infrared range finder, a platform and a support, wherein the balance ball is placed in the balance body, the balance ball is placed on the lower side of the platform, the platform is fixedly connected with the balance body, the crucible is detachably connected with the platform, the infrared range finder and the support are installed, and the support and the balance body establish a position relation.

Description

technical field [0001] The invention relates to a device capable of automatically measuring the height of crystal growth powder in a dry pot, belonging to the field of crystal growth. Background technique [0002] Crystal growth is a process in which a substance forms a crystal from a gas, liquid or solid phase under specific physical and chemical conditions. Before artificially preparing crystals, it is first necessary to put the powder for crystal growth into the crucible. The operator will measure the height of the powder with a ruler every time the powder is added to ensure the amount of powder required for crystal growth. The crucible needs to be shaken continuously to make the powder even and smooth when the material height is high. This work requires skilled and experienced operators, otherwise it is difficult to achieve the required accuracy. [0003] Based on the above problems, it is urgent to propose a device that can automatically measure the height of the cryst...
