Embodiment Construction

[0035] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0036] refer to figure 1 , the present invention a kind of crystal furnace control method, comprises the following steps:

[0037] After the crystal furnace system is started, the vacuum inside the crystal furnace is controlled by a vacuum pump and a diffusion pump;

[0038] When the vacuum degree inside the crystal furnace reaches the preset vacuum degree target, the crystal furnace starts to process the raw materials;

[0039] Adjust the growth environment according to the process requirements, and start crystal formation;

[0040] After the crystal formation is completed, the cooling process is performed, and the crystal furnace system is closed after the process.

[0041] In this embodiment, the present invention can effectively prevent oxidation of special materials in the furnace body by controlling the vacuum inside the furnace body. Th...

Abstract

The invention discloses a crystal furnace control method and system. The method herein includes: after a crystal furnace system is started, controlling interior vacuum degree of the crystal furnace through a vacuum pump and a diffusion pump; after the interior vacuum degree of the crystal furnace reaches a preset vacuum degree target, allowing the crystal furnace to start to treat materials; adjusting a growth environment according to process requirements, and starting generation of crystal; after crystal growth, cooling; shutting down the crystal furnace system after processing. The crystal growth process can be fully automated; oxidation of the special material of a furnace body can be prevented by controlling the interior vacuum degree of the crystal furnace; the service life of the crystal furnace is greatly extended. The crystal furnace control method and system are widely applicable to the field of crystal furnace control.

Description

technical field [0001] The invention relates to the technical field of crystal furnace control, in particular to a crystal furnace control method and system. Background technique [0002] IOLs are playing an increasingly important role in the fields of science and technology and industrial production, and the preparation equipment and technology of IOLs have become an important bottleneck restricting the production and quality of IOLs. The most advanced artificial crystal preparation technology is in the hands of developed countries such as the United States and Germany, and the corresponding equipment has a high degree of automation and is easy to achieve mass production. However, its high price discourages domestic enterprises and scientific research institutes. There are a few companies in China that can also provide IOL preparation equipment, but there are often problems such as low degree of automation, excessive reliance on operator experience, and low yield in mass p...
