Continuous charging device for artificial crystal growth

Abstract

The invention relates to a stable and automatic control continuous feeding device, especially a continuous feeding device for artificial crystal growth, including the crystal liquid level in the crucible, the artificial crystal is connected through a crystal lifting weighing system, and the crystal lifting weighing system is respectively connected with a computer and a computer. The electronic balance is connected, the hopper is fixedly connected to the base, one end of the feeding conduit is connected to the base, the other end is inserted into the crystal liquid surface in the crucible, a controllable motor is connected to the rotating shaft, and the material wheel is connected to the machine base through the rotating shaft. One end of the supporting plate is installed on the machine base, and the other end is cantilevered, and forms a continuous feeding gap with the material dial. It has simple structure, convenient installation, continuous and stable feeding, and no vibration. It is widely used in various occasions that require accurate and continuous feeding, especially for automatic and continuous feeding of artificial crystals. It can realize computer automatic program control management. Avoid manual operation errors, and can ensure the quality requirements for crystal growth such as lithium tantalate and lithium niobate.

Description

technical field [0001] The invention relates to a continuous feeding device for artificial crystals, in particular to a continuous feeding device used in a system for controlling the growth diameter of artificial crystals. Background technique [0002] Most of the continuous feeding devices in the prior art adopt vibration-type continuous feeding, compressed air-type continuous feeding, spiral-type continuous feeding and other forms. For the continuous feeding mechanism of artificial crystals, there are vibration-feeding artificial crystal feeding mechanisms, and there are also hole dials. Type intraocular lens feeding mechanism. The feeding of the above-mentioned types of feeding mechanisms has the fluctuation of the feeding, strictly speaking, it is not continuous feeding, especially the vibrating feeding type intraocular lens feeding mechanism is not easy to accurately weigh the change of the feeding through the electronic balance, so , it is diff...
