Automatic crystal manufacturing control method and device

Abstract

The invention discloses an automatic crystal manufacturing control method and device. The automatic crystal manufacturing control method comprises the steps that complete liquefaction process judgmentis carried out, specifically, liquefaction images of raw materials in a furnace are collected through high-definition image collection equipment, the collected images are compared with complete liquefaction images pre-stored in an image library, and a complete liquefaction command is output after successful comparison; crystal growth process judgment is carried out, specifically, enlarged imagesof the seed crystal placing position are collected through the high-definition image collection equipment, the images collected continuously are compared with pre-stored crystal growth process images,and when the collected image is matched with the corresponding pre-stored crystal growth process image, a command of the corresponding name is output; and command output is carried out, specifically,the results of complete liquefaction process judgment and crystal growth process judgment are converted into visual characters through visualization equipment to be output. The automatic crystal manufacturing control method and device have the advantages that the crystallization process can be judged rapidly and accurately, so that the controllability of the technology process is high; meanwhilethe control precision is high, and thus improvement of the product quality is facilitated.

Description

technical field [0001] The invention relates to the field of crystal manufacturing, in particular to an automatic crystal manufacturing control method and device. Background technique [0002] Crystallization is a very important process in the production process of sapphire and other crystals. The judgment of the crystallization process in the prior art is usually human judgment, and it is believed that judgments are prone to large errors, and human eyesight is limited, requiring repeated Confirmation can determine whether there is a deviation in the process, which will lead to a large process deviation, delay the timing of the best application process, and thus affect the quality of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic crystal manufacturing control method and device that can facilitate automatic control and improve control accuracy. [0004] In order to solve the above-menti...
