Weighing device in artificial crystal growth process

Abstract

The invention discloses a weighing device in the artificial crystal growth process. According to the weighing device, a bearing seat is fixedly arranged on a sliding seat; a rotating shaft is sleeved in a bearing of the bearing seat; a shaft center through hole is formed in the rotating shaft; the rotating shaft is in transmission connection with a motor; the upper end of the rotating shaft is fixedly connected with a rotating disc; a support plate is fixedly arranged on the rotating disc; a weighing sensor is fixedly arranged on the support plate; a transition seat is arranged on the end head of a cantilever of the weighing sensor; the transition seat is downwards hinged with a seed crystal shaft; the seed crystal shaft downwards penetrates through the shaft center through hole of the rotating shaft; a sealing hood is also fixedly arranged on the rotating disc; and the upper surface of the sealing hood is provided with a sealing socket and an electric brush ring. The weighing device has the beneficial effects that the structure is simple, the installation is simple, the accuracy is high, the quality of artificial crystals is improved, and the large-scale production is realized.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to a weighing device used in the growth process of artificial crystals. Background technique [0002] Laser crystal (YAG), sapphire crystal (Al 2 o 3 ) and other artificial crystals are the main materials for manufacturing lasers, semiconductor lighting, and high-end windows. The preparation (growth) of such artificial crystals is usually in a clean furnace room, under the condition of a protective atmosphere, the raw materials are melted by a heater, and then, by The seed crystal is guided to grow an ideal single crystal by pulling up; in order to stably and quickly grow a high-quality qualified single crystal, it is necessary to precisely control the diameter of the crystal to meet the needs of subsequent processes. [0003] The diameter control of the crystal in the prior art adopts the method of weighing from the bottom or the weighing mechanism with a built-in motor...
