[0002] The square silicon core is made of high-purity silicon core round rods and has a standard square plane structure. It is used as a heat carrier in the Siemens process and silane-generated polysilicon production, and is used for reduction reaction to deposit polysilicon. It is used together with the deposited silicon as polysilicon raw material, and is an indispensable material in polysilicon production.

[0003] In some use cases, the silicon core needs to be ground into a cone to create a silicon core with a specific conical structure to meet the needs of these applications. Conical grinding is the process of grinding a part of the silicon core into a cone. In semiconductor manufacturing, precise grinding and cutting are very important steps to ensure that the size and shape of the device meet the design requirements.

[0004] Since the silicon core has a certain length, it is inconvenient to process the silicon core if it is not supported during cone grinding. Also, since the silicon core has a variety of shapes, the silicon core will rotate with the processing equipment during cone grinding. Therefore, for the square silicon core, supporting the silicon core is an urgent problem to be solved. Utility Model Content

[0030] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0031] Please refer to Figure 1-Figure 8 The embodiment of the utility model provides a square silicon core grinding cone support structure, including a support rod 1, the support rod 1 is fixedly installed on the ground, and a first rotating component 2 is installed on the upper end of the support rod 1. The height of the first rotating component 2 is consistent with the height of the equipment for processing the workpiece.

[0032] Among them, the first rotating component 2 includes a fixed sleeve 21, which is connected to the support rod 1 by screws. An inner ring 23 is rotatably arranged in the fixed sleeve 21, and an extension tube 25 is connected to one side of the inner ring 23. A square slot is opened inside the extension tube 25. After the square workpiece is passed through the extension tube 25 and inserted into the processing equipment, the support rod 1 and the fixed sleeve 21 can be used to support the workpiece.

[0033] At the same time, an annular groove 22 is opened on the inner wall of the fixed sleeve 21, and a plurality of balls 24 are rotatably arranged in the annular groove 22. The inner ring 23 is rotated by the balls 24. When the workpiece rotates with the processing equipment, the force generated by the workpiece prompts the balls 24 to rotate with the inner ring 23, so that the support rod 1 and the fixed sleeve 21 always maintain the supporting effect on the workpiece.

[0034] Furthermore, a slide rail 3 is hinged at the lower end of the support rod 1, and an adjustment mechanism is slidably arranged in the slide rail 3. The upper end of the adjustment mechanism is movably connected to a second rotating component 4. The adjustment mechanism adjusts the position of the second rotating component 4 by sliding in the slide rail 3, and the slide rail 3 is usually rotated to one side of the support rod 1, so as to reduce the overall volume of the device. When encountering a long workpiece, the slide rail 3 is rotated to a state parallel to the ground, and the position of the adjustment mechanism and the second rotating component 4 is moved according to the length of the workpiece.

[0035] The structures of the first rotating assembly 2 and the second rotating assembly 4 are consistent.

[0036] The adjustment mechanism includes a pair of sliders 7 slidably arranged in the slide rail 3, a rotating rod 71 is arranged on one side of the pair of sliders 7, a hollow rod 8 is rotatably arranged between the pair of rotating rods 71, the position of the hollow rod 8 is adjusted by the sliding of the sliders 7, and it is rotated on the rotating rod 71 for easy storage.

[0037] Furthermore, an inner rod 9 is slidably arranged in the hollow rod 8, and a bolt 81 is threadedly connected to the hollow rod 8. The bolt 81 fixes the inner rod 9. After the inner rod 9 slides to the top of the hollow rod 8, the second rotating component 4 and the first rotating component 2 are on the same horizontal line.

[0038] In order to adjust the stability of the slider 7 , a screw rod 5 is rotatably provided on one side of the slide rail 3 , and the screw rod 5 is threadedly connected to the slider 7 . A slide rod 6 is fixedly provided on the other side of the slide rail 3 , and the slide rod 6 is slidably connected to another slider 7 .

[0039] In order to ensure that the second rotating component 4 is more stable during use, a sliding hole 92 is opened at the upper end of the inner rod 9, and a moving rod 93 is slidably arranged in the sliding hole 92. A limiting head 94 is arranged at the upper end of the moving rod 93. When the moving rod 93 slides upward with the limiting head 94, the limiting head 94 fixes the second rotating component 4, thereby effectively preventing the second rotating component 4 from rotating.

[0040] In addition, a support plate 91 is provided on one side of the second rotating assembly 4. When the inner rod 9 is retracted in the hollow rod 8 and the hollow rod 8 is moved to a suitable position, the second rotating assembly 4 rotates downward. Figure 1 As shown, the support plate 91 is located at the lower side of the workpiece to support the workpiece.

[0041] In summary, a square silicon core grinding cone support structure of an embodiment of the utility model has the following working principle: the workpiece is passed through the extension tube 25, and the workpiece is supported by the support rod 1 and the fixed sleeve 21. At the same time, the workpiece needs to be rotated during processing. The force generated by the rotation of the workpiece prompts the ball 24 to rotate with the inner ring 23, so that the fixed sleeve 21 and the support rod 1 always support the workpiece. According to the length of the workpiece, the adjustment mechanism can adjust the position of the second rotating component 4 according to the length of the workpiece, and the second rotating component 4 is used to strengthen the support of the workpiece.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
