Description

Technical Field

[0001] This invention belongs to the field of synthetic diamond technology, and more specifically, relates to an MPCVD growth substrate. Background Technology

[0002] MPCVD plays a significant role in the field of materials preparation, especially in the preparation of high-quality single-crystal diamond. With the development of science and technology, the demand for large-size, high-quality single-crystal diamond has surged in many high-tech fields. MPCVD has become the preferred method for preparing such single-crystal diamond due to its advantage of generating large-area, pure and stable plasma spheres in the deposition chamber. In order to facilitate the cultivation and processing of diamond, a growth platform is required.

[0003] For example, application number 202323066786.0 discloses an adjustable MPCVD growth platform, including a platform body. Three partitions are fixedly connected to the inner wall of the platform body. Several limiting mechanisms are provided inside the platform body. Adjustable posts are provided at the four corners of the bottom of the platform body. Each limiting mechanism includes a limiting plate, a limiting post, and two sliders. The bottom of the limiting post passes through the limiting plate and is in close contact with the top of the partition. This solves the problem that most existing MPCVD growth platforms lack the ability to limit the movement of the metal container holding the seed crystal. When the platform is moved to remove the metal container holding the seed crystal from the top of the platform, the container is prone to displacement or even falling off the top of the platform, and it is inconvenient to adjust the platform to a horizontal position, thus affecting the performance.

[0004] Based on existing technology, it has been found that in the actual application of existing MPCVD growth abutments, diamond seed crystals are usually evenly arranged on the surface of the abutment. However, after the diamond growth process is completed, the grown diamonds need to be clamped and removed one by one. This process is not only cumbersome, but also greatly increases the complexity of the operation when replacing the grown diamonds and repositioning new diamond seed crystals, due to the multiple individual clamping and placement actions involved. This seriously affects the efficiency of operation, brings many inconveniences to actual use, and is not conducive to efficient and continuous production operations. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model relates to an MPCVD growth platform, which solves the problem that after the diamond growth process is completed, the grown diamonds need to be clamped and removed one by one. This process is not only cumbersome, but also greatly increases the complexity of the operation when replacing the grown diamonds and placing new diamond seed crystals, due to the multiple individual clamping and placement actions involved.

[0006] This invention provides an MPCVD growth platform, achieved through the following specific technical means:

[0007] An MPCVD growth stage includes: a fixed base; a docking block inserted inside the fixed base; side blocks distributed in a circular pattern fixed to the outer wall of the docking block; a top plate on the top of the docking block; an external control frame fixed to the top of the top plate; a culture frame inserted inside the external control frame; rectangular culture through holes opened inside the culture frame; the bottom of the culture frame inserted into a dividing slot; baffle frames fixed to the inside of the culture through holes of the culture frame; culture blocks inserted into the inside of the culture through holes of the culture frame; and the bottom of the culture blocks inserted into the baffle frames.

[0008] Preferably, the top of the fixed base is provided with a circular groove; and the inner wall of the fixed base is fixed with inner concentric arc blocks distributed in a circular pattern.

[0009] Preferably, the docking block has a docking screw hole at its center; the side stop block is inserted into the gap of the inner arc block; the side stop block has a constraint groove; and the inner arc block is slidably connected in the constraint groove.

[0010] Preferably, a side stop block is inserted at the bottom of the top plate; the external control frame adopts a rectangular frame structure; the interior of the external control frame is provided with a dividing slot; and a hand control slot is provided on the outer wall of the external control frame.

[0011] Preferably, a connecting screw is fixed to the bottom of the top plate; the connecting screw is threaded into the mating screw hole.

[0012] Preferably, the top of the culture frame is provided with a connecting screw hole; an external pull rod is connected to the internal thread of the connecting screw hole; and a handle is fixed to the top of the external pull rod.

[0013] The MPCVD growth platform proposed in this invention has the following beneficial effects:

[0014] 1. The side blocks distributed in a circular pattern on the outer wall of the docking block cooperate with the inner arc blocks on the inner wall of the fixed base. Through the sliding connection of the constraint slot, the stability of the connection between the fixed base and the docking block is effectively maintained, thereby providing stable support for the entire base structure. This ensures that the seed crystal can be in a stable environment during the diamond growth process, which is conducive to improving the growth quality of diamond.

[0015] 2. The internal dividing slots of the external control frame work in conjunction with the cultivation frame to precisely divide the cultivation space of the seed crystal, providing an orderly environment for diamond growth, which helps to improve the controllability and consistency of the growth process, thereby improving product quality and yield.

[0016] 3. The internal baffle frame of the culture frame not only shields the culture blocks to prevent them from shifting during the culture process, but also allows for the unified removal of the internal culture blocks when the culture frame needs to be dismantled. In addition, the connection screw hole at the top of the culture frame and the external pull rod make it easy for operators to remove the culture frame and internal culture blocks together at once using the handle, which greatly improves the efficiency of maintenance and replacement and reduces operation time and labor costs.
