Abstract

The invention discloses a method and system for self-adaptive regulation and control of crystal growth power supply parameters. The method includes: obtaining first control parameters according to the first crystal growth power supply; obtaining first particle diameter characteristic information; The information and the first temperature information are input into the particle size change trend prediction model to obtain the first particle size change trend information; the trend change probabilities are sorted according to the preset sorting rules to obtain the first sorting result; according to the first sorting result, the obtained The first particle size change trend; judging whether the first particle size change trend meets the preset particle size change trend; if the preset particle size change trend is satisfied, control the first crystal growth power supply to output the first voltage amplitude, the first current amplitude, and the first pulse frequency. It solves the technical problem that the state change of the crystal itself and the temperature difference in the crystal furnace are not considered in the prior art, resulting in low flexibility and increased probability of sintering failure.

Description

technical field

[0001] The invention relates to the related fields of power supply control of crystal heating furnaces, in particular to a method and system for self-adaptive regulation and control of crystal growth power supply parameters. Background technique

[0002] At present, crystal materials are more and more widely used in electronic applications, aerospace, optics and other fields, which leads to a corresponding increase in market demand, and puts forward higher requirements for the processing quality of crystal materials. At present, the production of crystals is mostly through crystal furnaces and a Therefore, how to regulate the processing of the crystal furnace to increase the processing quality of crystal materials has become the main research direction at present.

[0003] The crystal furnace is a kind of manufacturing equipment. The temperature change in the crystal furnace directly affects the growth of the crystal and the quality of the grown crystal. At p...
