Abstract

The invention discloses a growth device for an artificial crystal. The growth device comprises a tray, a plurality of crucibles, a heat preserving mechanism, an external heater and a central heater, wherein the plurality of crucibles are arranged around the tray along a circumferential direction; the heat preserving mechanism is arranged above the tray, and is provided with a hollow cavity for accommodating the plurality of crucibles; the external heater is arranged in the heat preserving mechanism, and is positioned on the peripheries of outer sides of the plurality of crucibles; the central heater is arranged in the heat preserving mechanism, and is positioned in the surrounding center of the plurality of crucibles. According to the growth device for the artificial crystal, the central heater is arranged in surrounding center of the plurality of crucibles to perform heating temperature compensation on a central region of a thermal field, thereby forming a uniform thermal field area being heated internally and externally, increasing the uniformity of the temperature in a large-diameter thermal field, increasing the production efficiency, lowering the production cost, and enhancing the quality of the grown artificial crystal.

Description

Technical field [0001] The invention relates to the technical field of artificial crystal growth, in particular to a growth device for artificial crystals. Background technique [0002] With the rapid development of the artificial lens material application market, in order to improve the productivity of the artificial lens and reduce the production cost of the artificial lens, the growth of the artificial lens gradually develops in the direction of multiple crucibles. [0003] In the prior art, the process thermal field uses peripheral heating to perform processes such as melting of raw materials, crystal growth, and annealing. With the increase in the number of crucibles, the diameter of the thermal field for growing intraocular lens materials becomes larger and larger, which makes it difficult to ensure the temperature uniformity in the thermal field, which leads to a decrease in the inherent quality of the grown intraocular lens material, which affects The performance of the gr...
