Description

Technical Field

[0001] This utility model relates to the field of crystal material preparation technology, specifically a device for making diamond seed crystals transparent. Background Technology

[0002] Diamond, also known as "diamond," is a mineral composed of carbon. It is an allotrope of graphite, with the chemical formula C, and is the precursor to diamonds. Diamond is the hardest naturally occurring substance in nature. Graphite can be transformed into synthetic diamonds under high temperature and pressure. Diamonds have a wide range of uses, such as in handicrafts, industrial cutting tools, and are also a precious gemstone.

[0003] In the process of making diamond seed crystals transparent, the seed crystal is usually placed in a plasma environment. By applying a pulsed voltage, ions in the plasma are accelerated and injected into the seed crystal surface, thereby changing its atomic structure and chemical composition to improve the transparency of the diamond. During this process, the diamond seed crystal needs to be clamped. However, due to the varying sizes and shapes of diamond seed crystals, it is sometimes difficult to achieve complete clamping. In a plasma environment, if the seed crystal is not completely clamped, the relative position of its surface and the ion beam may shift or fluctuate. This will cause significant differences in the depth, angle, and dose of ion implantation in different regions of the seed crystal, thus affecting the uniformity of the surface atomic structure and chemical composition.

[0004] Therefore, this utility model provides a diamond seed crystal transparency treatment device to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This invention provides a device for making diamond seed crystals transparent, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a diamond seed crystal transparency treatment device, which includes a base plate, a support frame fixedly mounted on the base plate, a vacuum tank fixedly mounted on the support frame, a top cover disposed above the vacuum tank, a pulse power supply fixedly mounted on the top cover, a placement platform disposed below the top cover, and a clamping mechanism disposed on the placement platform for clamping the diamond seed crystal.

[0009] The clamping mechanism includes a clamping block disposed on the placement platform, a cavity formed inside the clamping block, a slide rod slidably mounted inside the cavity, a spring sleeved on the slide rod, a baffle fixedly mounted on the spring, a positioning rod fixedly mounted on the baffle, a limiting frame slidably mounted inside the clamping block, a threaded rod rotatably mounted on the clamping block, and a first handwheel fixedly mounted on the threaded rod.

[0010] As a preferred technical solution of this application, one end of the spring is fixedly connected to the inner wall of one side of the cavity, and the other end of the spring is fixedly connected to one side of the baffle. The cavity passes through the clamping block, and the threaded rod passes through the limiting frame. The limiting frame has a threaded hole that matches the threaded rod inside.

[0011] As a preferred technical solution of this application, the placement platform has a groove inside, one of the grooves is fixedly connected to a limit rod, and the other groove is rotatably connected to a bidirectional lead screw.

[0012] As a preferred technical solution of this application, the bidirectional lead screw passes through the groove, one end of the bidirectional lead screw is fixedly connected to a second handwheel, and the clamping block is slidably connected inside the groove.

[0013] As a preferred technical solution of this application, both the limiting rod and the bidirectional lead screw pass through the clamping block, and the clamping block has a threaded groove inside that is adapted to the threaded rod.

[0015] (III) Beneficial Effects

[0016] This utility model has a simple structure and is easy to use. Through the clamping mechanism, as the clamping block continues to move, the positioning rod is squeezed according to the contour of the crystal seed surface, resulting in different degrees of movement. The movement of the positioning rod drives the sliding rod and the baffle to move synchronously in the cavity. When the diamond crystal seed is completely fixed, the first handwheel is turned manually, which drives the threaded rod to rotate synchronously, thereby causing the limiting frame to descend. The insert on the limiting frame clamps multiple sliding rods, thus effectively clamping and fixing diamond crystal seeds of different sizes and shapes, preventing shaking or displacement during the transparency process, and improving the stability and accuracy of the process.

Detailed Implementation

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a transparency processing device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the diamond seed crystal transparency treatment device includes a base plate 1, a support frame 2 fixedly mounted on the base plate 1, a vacuum tank 3 fixedly mounted on the support frame 2, a top cover 4 disposed above the vacuum tank 3, a pulse power supply 5 fixedly mounted on the top cover 4, a placement platform 6 disposed below the top cover 4, and a clamping mechanism disposed on the placement platform 6 for clamping the diamond seed crystal.

[0027] The clamping mechanism includes a clamping block 7 disposed on the placement platform 6, a cavity 8 opened inside the clamping block 7, a slide rod 9 slidably installed inside the cavity 8, a spring 10 sleeved on the slide rod 9, a baffle 11 fixedly installed on the spring 10, a positioning rod 12 fixedly installed on the baffle 11, a limiting frame 13 slidably installed inside the clamping block 7, a threaded rod 14 rotatably installed on the clamping block 7, and a first handwheel 15 fixedly installed on the threaded rod 14.

[0028] One end of the spring 10 is fixedly connected to the inner wall of one side of the cavity 8, and the other end of the spring 10 is fixedly connected to one side of the baffle 11. The clamping block 7 passes through the cavity 8, and the threaded rod 14 passes through the limiting frame 13. The limiting frame 13 has a threaded hole that matches the threaded rod 14.

[0029] When operating the diamond seed crystal transparency treatment device, the base plate 1 must first be placed in a suitable position. Then, the diamond seed crystal is placed between two clamping blocks 7. Next, the clamping blocks 7 move towards the center, and multiple positioning rods 12 initially contact the surface of the diamond seed crystal. As the clamping blocks 7 continue to move, the positioning rods 12 are compressed according to the contour of the seed crystal surface, resulting in varying degrees of movement. The movement of the positioning rods 12 causes the slide rods 9 and baffles 11, which are fixedly connected to them, to move synchronously within the cavity 8. The movement of the baffles 11 compresses the spring 10. After the diamond seed crystal is completely fixed, the first handwheel 15 is manually rotated. The rotation of the first handwheel 15 causes the threaded rod 14, which is fixedly connected to it, to rotate synchronously, thereby causing the limiting frame 13 to descend. The inserts on the limiting frame 13 clamp the multiple slide rods 9. To fix the diamond seed crystal, the top cover 4 is placed over the vacuum tank 3 to ensure its internal sealing. Then, the vacuum tank 3 is evacuated to a vacuum state, and the pulse power supply 5 is activated. The pulse power supply 5 generates a high-energy pulse electric field to make the diamond seed crystal inside the vacuum tank 3 transparent. After the treatment is completed, the pulse power supply 5 is turned off, and the internal pressure of the vacuum tank 3 is allowed to return to normal pressure. Then, the top cover 4 is opened, and the threaded rod 14 is rotated in the opposite direction by rotating the first handwheel 15, causing the limit frame 13 to rise and release the clamping of the slide rod 9. At this time, the spring 10 pushes the baffle 11 and the slide rod 9 to reset under the action of elastic restoring force, and the positioning rod 12 also resets, thereby releasing the diamond seed crystal. Finally, the treated diamond seed crystal is taken out from the clamping mechanism for subsequent processing or testing.

[0030] Furthermore, to facilitate the movement of clamping block 7, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the placement platform 6 has a groove 16 inside, one of which is fixedly connected to a limit rod 17, and the other is rotatably connected to a bidirectional lead screw 18.

[0031] A bidirectional lead screw 18 passes through a groove 16, and a second handwheel 19 is fixedly connected to one end of the bidirectional lead screw 18. A clamping block 7 is slidably connected inside the groove 16.

[0032] Both the limiting rod 17 and the bidirectional lead screw 18 pass through the clamping block 7, and the clamping block 7 has a threaded groove inside that matches the threaded rod 14.

[0033] When the diamond seed crystal transparency treatment device is in use, rotating the second handwheel 19 causes the bidirectional lead screw 18 to rotate accordingly. Since the bidirectional lead screw 18 is threadedly connected to the clamping block 7, the rotation of the bidirectional lead screw 18 can drive the two clamping blocks 7 to move simultaneously in opposite or opposite directions, thereby achieving rapid clamping or loosening of the diamond seed crystal. This design not only improves the moving efficiency of the clamping block 7, but also makes the operation simpler. At the same time, the setting of the limit rod 17 can ensure the stability of the clamping block 7 during the movement process, preventing it from shifting or shaking, further ensuring the stability and safety of the diamond seed crystal during the transparency treatment process.

[0034] Furthermore, to facilitate the movement of the top cover 4, such as... Figure 1 , Figure 2 and Figure 3 As shown, multiple electric push rods 20 are fixedly connected to the top of the support frame 2. The movable end of the electric push rod 20 is fixedly connected to the bottom of the top cover 4. A connecting rod 21 is fixedly connected to the bottom of the top cover 4. The end of the connecting rod 21 away from the top cover 4 is fixedly connected to the top of the placement platform 6.

[0035] When in use, the telescopic function of the electric push rod 20 allows the top cover 4 to be easily raised and lowered, making it convenient for users to open or close the vacuum tank 3 to place or remove the diamond seed crystals.

[0036] 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.
