Description

Technical Field

[0001] The utility model relates to the technical field of crystal manufacturing, in particular to a crystal growth lifting device and a crystal growth furnace. Background Art

[0002] In an automatic crystal growth furnace (for example, in the automatic growth process of YAG crystal, i.e., yttrium aluminum garnet), since the grown crystal becomes larger and heavier, and with the rotation of the crystal itself, when the crystal grows to the later stage, due to the slight deviation of the center of gravity and the action of centrifugal force, the weighing signal fluctuates more and more, which brings more interference to the automatic control of the crystal.

[0003] The reference patent is named: Crystal Growth Lifting Device and Crystal Growth Furnace (Authorized Publication No.: CN 212533194U), which includes: a rotating mechanism, and a rod member is connected to the output end of the rotating mechanism; a weighing mechanism, which is arranged on the fixed part of the rotating mechanism; the weighing mechanism includes two or more weighing members. The crystal growth lifting device provided by this patent significantly improves the accuracy of the crystal weight measurement result, and can largely avoid the influence of the tangential force generated during crystal rotation on the measurement result. And the measurement result is used as control information, which can avoid affecting the automatic growth of the crystal, thus ensuring the growth quality of the crystal.

[0004] Since different crystal materials have different requirements for the lifting speed, and the existing crystal growth lifting device cannot adjust the lifting speed of the crystal, it may lead to non-uniform morphology, defects, branches or rough surfaces due to too fast or too slow growth speed. In addition, during the lifting process, too fast lifting speed may cause stress, cracks or inclusions inside the crystal, thus affecting its overall quality, while too slow lifting speed may cause the crystal to be exposed to the high-temperature melt for a long time, increasing the risk of impurities entering the crystal and reducing the purity of the crystal.

[0005] Therefore, it is necessary to provide a new crystal growth lifting device and crystal growth furnace to solve the above technical problems. Summary of the Utility Model

[0006] To solve the above technical problems, the utility model provides a crystal growth lifting device and a crystal growth furnace.

[0008] A lifting assembly, which is installed at the top of the main body, includes a discharge pipe fixed to the top of the main body, and a lifting device is slidably connected to the inner side of the discharge pipe;

[0009] The sliding assembly is installed on the top of the main body, and includes a support frame fixed on the top of the main body. A limiting block is fixed on the side of the support frame close to the discharge pipe, and an adjustment assembly for adjusting the lifting speed of the lifting equipment is installed on the outer wall of the support frame.

[0010] Preferably, the sliding assembly includes a rotating rod rotatably connected to the inner side of the support frame via a bearing, one end of the rotating rod is rotatably connected to a swing bar via a bearing, both ends of the swing bar are symmetrically rotatably connected to connecting bars via bearings, the inner side of the connecting bar is rotatably connected to a sliding bar via a bearing, and the other end of the rotating rod is equipped with a driving assembly for driving the rotating rod to rotate.

[0011] Preferably, the adjustment assembly includes an adjustment plate fixed on the top of the lifting device, the outer wall of the adjustment plate is symmetrically provided with racks, the outer wall of the sliding bar is fixed with a connecting column, the outer wall of the connecting column is rotatably connected with a toggle bar through a bearing, the toggle bar is meshed and connected with the inner side of the rack, the outer wall of the adjustment plate is provided with a sliding groove, and the inner side of the sliding groove is slidably connected to the outer wall of the limit block.

[0012] Preferably, the driving assembly comprises a fixing plate fixed on the outer wall of the supporting frame, a motor is fixed on the top of the fixing plate, and an output end of the motor is fixed to one end of the rotating rod.

[0015] Compared with the related art, the crystal growth pulling device and crystal growth furnace provided by the utility model have the following beneficial effects:

[0016] 1. Since different crystal materials have different requirements for the pulling speed, and the existing crystal growth pulling device cannot adjust the pulling speed of the crystal, the pulling mechanism can automatically adjust the pulling speed, thereby accurately controlling the growth characteristics and requirements of the crystal, ensuring that the crystal grows under the best conditions, which helps to reduce the stress, cracks and inclusions inside the crystal and improve the overall quality of the crystal;

[0017] 2. In addition, by automatically adjusting the pulling speed, the growth rate of the crystal can be controlled more efficiently to avoid growth problems caused by too fast or too slow growth. This helps to shorten the growth cycle, improve production efficiency, and reduce the pollution and defects that may be introduced by long-term growth. BRIEF DESCRIPTION OF THE DRAWINGS
