It provides a specific environment for crystal growth, such as controlling temperature and pressure, so that the crystal can grow in the expected way to obtain the desired crystal and facilitate subsequent processing.

[0003] During the rotation of the seed crystal rod, vibration or deviation may occur, causing the seed crystal rod to collide or rub against the quartz tube wall. The vibration of the seed crystal rod affects the normal growth of the crystal and is prone to internal defects such as crystal delamination and scattering. In order to solve the above problems, there is an urgent need for a vibration prevention device for the quartz seed crystal rod of the crystal growth furnace. Utility Model Content

Vibration of the seed crystal rod affects the normal growth of the crystal and can easily lead to internal defects such as crystal delamination and scattering. Therefore, an anti-vibration device for the quartz seed crystal rod of a crystal growth furnace is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quartz seed rod anti-vibration device for a crystal growth furnace, comprising a support, a sliding rod fixedly connected to the top surface of the support, a first threaded rod fixedly connected to the top surface of the support, a movable module provided on the outer wall of the first threaded rod, the movable module being slidably connected to the sliding rod through a through hole therein, a support frame fixedly connected to one side of the movable module, a motor fixedly connected to one end of the support frame, the output shaft of the motor being fixedly connected to the seed rod, an adjustment component provided on the outer wall of the sliding rod, and a fixing component provided on one side of the adjustment component;

[0006] The fixing component includes a mounting rod, which is slidably connected to a connecting rod through a groove opened in its interior. The mounting rod is threadedly connected to a first bolt through a threaded hole opened in its outer wall. A fixing bracket is fixedly connected to one end of the connecting rod. A second bolt is threadedly connected to the fixing bracket through a threaded hole opened in its interior. A buffer pad is fixedly connected to one end of the second bolt.

[0007] As a further description of the above technical solution:

[0008] The first bolt passes through the mounting rod and one end of the first bolt is in contact with the connecting rod.

[0009] As a further description of the above technical solution:

[0010] The fixing frame has an opening on one side, and the second bolts are provided in three parts and distributed on the fixing frame at a certain angle.

[0011] As a further description of the above technical solution:

[0012] The fixing frame is ring-shaped and the seed crystal rod is located at the center of the fixing frame.

[0013] As a further description of the above technical solution:

[0014] The adjustment assembly includes a fixing block, which is slidably connected to a slide rod through a through hole therein.

[0015] As a further description of the above technical solution:

[0016] A limiting ring is fixedly connected to one side of the fixed block, and a second threaded rod is rotatably connected to the limiting ring through a through hole therein.

[0017] As a further description of the above technical solution:

[0018] The fixing block is slidably connected to a threaded sleeve through a groove opened inside it, and one end of the threaded sleeve is fixedly connected to an extrusion plate.

[0019] As a further description of the above technical solution:

[0020] One end of the second threaded rod is threadedly connected to the threaded sleeve, and one side of the fixing block is fixedly connected to one end of the mounting rod.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, by providing a second bolt inside, the fixing frame is adjusted to a suitable height by adjusting the adjustment component during use, so that the seed crystal rod enters the fixing frame from one side and is located in the center of the fixing frame. Then, by rotating the second bolt, the buffer pad is moved and comes into contact with the seed crystal rod. Through this design, when the seed crystal rod is rotated by the motor during the crystallization process, the second bolt can limit the seed crystal rod and prevent it from shaking during the rotation, thereby preventing the shaking of the seed crystal rod from affecting the normal growth of the crystal.

[0023] 2. In this utility model, by providing an extrusion plate inside, the position of the fixing frame can be adjusted by sliding and rotating the fixed block on the surface of the slide rod during use. At the same time, when the position is adjusted to a suitable position, the threaded sleeve can be moved by rotating the second threaded rod, which in turn moves the extrusion plate, thereby fixing the fixing block. Through this design, the fixing block can be fixed in different positions according to different needs during use, thus facilitating the installation and use of the fixing components.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4This utility model provides a technical solution: a quartz seed rod anti-vibration device for a crystal growth furnace, including a support 1, a sliding rod 3 fixedly connected to the top surface of the support 1, a first threaded rod 2 fixedly connected to the top surface of the support 1, a movable module 4 provided on the outer wall of the first threaded rod 2, the movable module 4 being slidably connected to the sliding rod 3 through a through hole therein, a support frame 5 fixedly connected to one side of the movable module 4, a motor 6 fixedly connected to one end of the support frame 5, a seed rod 8 fixedly connected to the output shaft of the motor 6, an adjustment component 7 provided on the outer wall of the sliding rod 3, and a fixing component 9 provided on one side of the adjustment component 7;

[0032] The fixing component 9 includes a mounting rod 91, which is slidably connected to a connecting rod 93 through a groove in its interior. The mounting rod 91 is threadedly connected to a first bolt 92 through a threaded hole in its outer wall. One end of the connecting rod 93 is fixedly connected to a fixing bracket 94. The fixing bracket 94 is threadedly connected to a second bolt 96 through a threaded hole in its interior. One end of the second bolt 96 is fixedly connected to a buffer pad 95.

[0033] The first bolt 92 passes through the mounting rod 91 and one end of the first bolt 92 contacts the connecting rod 93. The fixing frame 94 has an opening on one side. The second bolt 96 is provided in three parts and is distributed on the fixing frame 94 at a certain angle. The fixing frame 94 is annular and the seed crystal rod 8 is located at the center of the fixing frame 94.

[0034] The specific implementation method is as follows: During use, the fixing frame 94 is adjusted to a suitable height by adjusting component 7, and the connecting rod 93 is pulled to extend to a suitable length. Then, the connecting rod 93 is fixed by rotating the first bolt 92 and pressing it. The seed crystal rod 8 enters the fixing frame 94 from one side and is positioned in the center of the fixing frame 94. The buffer pad 95 is moved by rotating the second bolt 96 and comes into contact with the seed crystal rod 8. Since the surfaces of the buffer pad 95 and the seed crystal rod 8 are relatively smooth, the seed crystal rod 8 will not vibrate when the motor 6 drives the seed crystal rod 8 to rotate.

[0035] The adjusting component 7 includes a fixing block 71, which is slidably connected to the slide rod 3 through a through hole. A limiting ring 72 is fixedly connected to one side of the fixing block 71. A second threaded rod 75 is rotatably connected to the limiting ring 72 through a through hole. A threaded sleeve 74 is slidably connected to the fixing block 71 through a groove. A pressing plate 73 is fixedly connected to one end of the threaded sleeve 74. One end of the second threaded rod 75 is threadedly connected to the threaded sleeve 74. One side of the fixing block 71 is fixedly connected to one end of the mounting rod 91.

[0036] The specific implementation method is as follows: When in use, the position of the fixing frame 94 can be adjusted by sliding and rotating the moving fixing block 71 on the surface of the slide rod 3. At the same time, when the position is adjusted to a suitable position, the second threaded rod 75 can be rotated to drive the threaded sleeve 74 to move and drive the pressing plate 73 to move. The pressing plate 73 presses the slide rod 3, thereby increasing the friction between the pressing plate 73 and the slide rod 3, thereby fixing the fixing block 71.

[0037] Working principle: During use, the position of the fixed frame 94 can be adjusted by sliding and rotating the fixed block 71 on the surface of the slide rod 3. When the position is adjusted to a suitable position, the second threaded rod 75 can be rotated to move the threaded sleeve 74 and the extrusion plate 73. The extrusion plate 73 extrudes the slide rod 3, thereby increasing the friction between the extrusion plate 73 and the slide rod 3, thus fixing the fixed block 71. The connecting rod 93 is pulled to extend to a suitable length. Then, the first bolt 92 is rotated to extrude the connecting rod 93 and fix it. The seed crystal rod 8 enters the fixed frame 94 from one side and is positioned in the center of the fixed frame 94. The second bolt 96 is rotated to move the buffer pad 95 and bring it into contact with the seed crystal rod 8. Since the surfaces of the buffer pad 95 and the seed crystal rod 8 are relatively smooth, the seed crystal rod 8 will not vibrate when the motor 6 drives it to rotate.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
