[0002] At present, when producing diamond slices, the silicon carbide substrate needs to be placed upright, so a silicon carbide substrate carbon deposition fixture 50 is used. Figure 4 The silicon carbide substrate is held upright by a carbon deposition fixture 50. However, during placement, the clamping seat of the carbon deposition fixture 50 must be positioned in the middle of the silicon carbide substrate's outer circumference.

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0026] Example 1:
[0027] See Figure 1-3 A silicon carbide substrate positioning device includes a base 10, one side of which is provided with a positioning structure, four support seats 12 are installed on the upper end surface of the base 10, and a positioning seat 20 is installed on the support seat 12. The positioning seat 20 extends toward the side of the base 10 where the positioning structure is provided, and a positioning notch 21 is provided on the positioning seat 20. When in use, see Figure 5 The silicon carbide substrate carbon deposition fixture 50 is positioned through the positioning structure on the base 10, and then the silicon carbide substrate 60 is positioned through the positioning notch 21. When placing the silicon carbide substrate 60, the silicon carbide substrate 60 is inserted through the positioning notch 21, so that the silicon carbide substrate 60 can be accurately clamped by the clamping seat of the fixture.
[0028] In this embodiment, the positioning seat 20 can be a U-shaped slot welded to the support seat 12. The silicon carbide substrate carbon deposition fixture 50 can be pushed in and out through the positioning structure. The width of the positioning notch 21 is slightly larger than the thickness of the silicon carbide substrate 60, and the positioning notch 21 is aligned with the clamping seat.
[0029] In one embodiment, the positioning structure is a mark provided on the base 10. As long as the silicon carbide substrate carbon deposition fixture 50 is aligned with the mark, the silicon carbide substrate carbon deposition fixture 50 can be aligned with the positioning notch 21.
[0030] In another embodiment, see Figure 1 、 2 3. The positioning structure is two protruding blocks 11 set on one side of the base 10. A positioning area is formed between the two protruding blocks 11. The bottom plate of the silicon carbide substrate carbon deposition fixing device 50 is just stuck between the two protruding blocks 11 for positioning.
[0031] Example 2:
[0032] Based on Example 1, see Figure 1 、 2 The positioning seat 20 includes two baffles 22, which are respectively installed on both sides of the support seat 12, and the positioning gap 21 is formed between the two baffles 22. In this embodiment, the two baffles 22 are respectively welded to both sides of the support seat 12.
[0033] Example 3:
[0034] Based on Example 2, see Figure 2 、 3 The support base 12 is provided with a through hole 13, the shaft 30 passes through the through hole 13, and the baffles 22 are fixedly connected to the shaft 30. Through the above structure, the baffles 22 can rotate, such as Figure 2After the silicon carbide substrate 60 is placed, the baffle 22 is turned upward to facilitate the removal of the silicon carbide substrate carbon deposition fixture 50 .
[0035] Further. See Figure 1 、 3 , a step 14 is provided on the support seat 12 to limit the baffle 22. Figure 1 In the embodiment, the baffle 22 is kept in a horizontal state by the limitation of the step 14 .
[0036] Further, in order to facilitate the rotation of the baffle 22, see Figure 1 、 2 A handle 31 is provided on the rotating shaft 30.
[0037] The working principle or action process of the utility model is as follows:
[0038] When using, see Figure 4 The positioning device of the present application is installed on the workbench 40. First, the handle 31 is turned to flip the baffle 22, and the bottom plate of the silicon carbide substrate carbon deposition fixture 50 is clamped between the two protruding blocks 11, thereby positioning the silicon carbide substrate carbon deposition fixture 50. Then, the handle 31 is turned to flip the baffle 22 so that the baffle 22 is in a horizontal state, as shown in FIG. Figure 5 shown.
[0039] Thereafter, the silicon carbide substrate 60 can be inserted through the positioning notch 21 , so that the silicon carbide substrate 60 can be accurately clamped by the clamping seat of the silicon carbide substrate carbon deposition fixture 50 .
[0040] After the silicon carbide substrate 60 is installed, the handle 31 is rotated again, and the end of the handle 31 contacts and supports the workbench 40 to position the baffle 22. After that, the silicon carbide substrate carbon deposition fixture 50 can be taken out.
