[0003] The utility model patent application with application number 2025202304202 is for a boron-doped diamond powder deposition device applied for by our company. This device uses vibration to deposit diamond powder. In practical applications, due to the influence of the installation position of the vibrator and the uneven stress of the vibration container, the vibration intensity at the bottom of the vibration container varies, resulting in uneven distribution of diamond powder substrate during vibration, which affects the deposition effect.

[0029] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0030] Example 1:
[0031] Please see Figure 1-3 A diamond powder deposition apparatus includes a ring seat 10, a rotating ring 20, a vibrating container 30, a vibrator 40, a driving device, and a conductive slip ring 70. The rotating ring 20 is rotatably mounted on the ring seat 10. The vibrating container 30 is mounted on the top of the rotating ring 20, and the vibrator 40 is mounted on the bottom of the vibrating container 30. The conductive slip ring 70 is mounted in the middle of the ring seat 10. A wire on one side of the conductive slip ring 70 is electrically connected to the vibrator 40, and a wire on the other side passes through the ring seat 10. The driving device is used to drive the rotating ring 20 to rotate. A rotating ring 20 is mounted on the ring seat 10 and rotates under the drive of a drive device. The vibration container 30 is mounted on the rotating ring 20 and can also rotate. The vibration container 30 is vibrated by a vibrator 40 mounted at the bottom. When preparing boron-doped diamond powder, the diamond powder substrate inside the vibration container 30 will vibrate continuously. The rotation of the vibration container 30 counteracts the effects of the installation position of the vibrator 40 and the uneven stress of the vibration container 30, so that the diamond powder substrate can be more evenly dispersed during vibration, thus improving the deposition effect of diamond powder.
[0032] In this embodiment, the vibrator 40 is a vibration motor. The conductive slip ring 70 is the MT50119 series through-hole conductive slip ring from Shenzhen Mofulong Electronics Co., Ltd.
[0033] In this embodiment, see Figure 2 , 3 The ring seat 10 is rotatably connected to the rotating ring 20 via the bearing 11.
[0034] In this embodiment, the vibrating container 30 includes an annular sidewall 31, an upper flange 32, and a bottom wall 34. The upper end of the annular sidewall 31 is provided with an outwardly extending upper flange 32, and the lower end of the annular sidewall 31 is provided with a bottom wall 34. The upper flange 32 is mounted on the rotating ring 20 by an elastic member 21, resulting in a simple structure. The elastic member 21 is used to filter the vibration of the vibrating container 30 and prevent the vibration of the vibrating container 30 from being transmitted to the rotating ring 20.
[0035] The elastic element 21 can be made of multiple springs, with the upper and lower ends of the springs fixedly connected to the rotating ring 20 and the upper flange 32, respectively. The elastic element 21 can also be made of rubber rings, with the upper and lower sides of the rubber rings bonded and fixedly connected to the rotating ring 20 and the upper flange 32, respectively.
[0036] In this embodiment, the vibrating container 30 is made of molybdenum or tungsten or their alloys.
[0037] Example 2:
[0038] The difference from Example 1 is that, see [link to example]. Figure 2 , 3 The vibrating container 30 includes an annular sidewall 31, an upper flange 32, and a bottom wall 34. The upper end of the annular sidewall 31 is provided with an outwardly extending upper flange 32, and the lower end of the annular sidewall 31 is provided with a bottom wall 34. The upper flange 32 is mounted on the rotating ring 20. The annular sidewall 31 has a corrugated tubular structure. Because the annular sidewall 31 has a corrugated tubular structure, it has better axial extensibility. When the vibrator 40 vibrates, it can filter out most of the left-right vibration of the bottom wall 34, thereby allowing the bottom wall 34 to vibrate more fully up and down. This is because left-right vibration will cause the powder to disperse in all directions, while up and down vibration keeps the powder within the vibrating container 30.
[0039] Furthermore, the lower end of the annular sidewall 31 is provided with an inwardly projecting lower flange 33, and the bottom wall 34 is fixedly supported on the lower flange 33. This structure allows the annular sidewall 31 to be made of a more elastic material. In this design, the bottom wall 34 of the vibration container 30 is made of molybdenum, tungsten, or their alloys.
[0040] Furthermore, the upper flange 32 is mounted on the rotating ring 20 via the elastic element 21.
[0041] Example 3:
[0042] Based on Example 1 or 2, see Figure 2 , 3 A support rod 12 is installed on the inner wall of the ring seat 10, and a central column 13 is installed on the lower side of the support rod 12. The central column 13 passes into the central hole of the conductive slip ring 70, and the central hole of the conductive slip ring 70 is fixed to the central column 13 by screws. With the above structure, when the rotating ring 20 and the vibrating container 30 rotate, the support rod 12 rotates with the rotating ring 20. Since the central column 13 is fixed to the central hole of the conductive slip ring 70, the central rotating part of the conductive slip ring 70 rotates with the central column 13. The wires on the central rotating part of the conductive slip ring 70 will also rotate synchronously, instead of being pulled to rotate, thus improving the service life of the wires.
[0043] When using the MT50119 series through-hole conductive slip ring, a mounting base is provided on the outer wall of the conductive slip ring. The mounting base is fixed to the bottom of the ring seat 10 by screws. A screw is screwed onto the central rotating part of the conductive slip ring 70. After the central column 13 passes through the central rotating part of the conductive slip ring 70, this screw is tightened.
[0044] Example 4:
[0045] Based on Example 1, 2, or 3, see [link to example]. Figure 2 , 3 The drive device includes an internal gear ring 50 and a drive motor 60. The internal gear ring 50 is installed inside the rotating ring 20, and the drive motor 60 is installed inside the ring seat 10 through the bracket 14. The output shaft of the drive motor 60 is equipped with a gear 61, which meshes with the internal gear ring 50 for transmission.
[0046] When the drive motor 60 rotates, it drives the gear 61 to rotate. The rotation of the gear 61 drives the internal gear ring 50 to rotate, which in turn drives the rotating ring 20 to rotate, thereby driving the vibrating container 30 to rotate.
[0047] In another embodiment, the drive unit includes an external gear ring and a drive motor 60. The external gear ring is mounted on the outer wall of the rotating ring 20, and the drive motor 60 is mounted on the outer wall of the ring seat 10. A gear 61 is mounted on the output shaft of the drive motor 60, and the gear 61 meshes with the external gear ring for transmission. Specifically, a mounting plate is laterally fixed to the outer wall of the ring seat 10. The drive motor 60 is mounted on the lower side of the mounting plate, and the output shaft of the drive motor 60 passes through the mounting plate. The gear 61 is mounted on the output shaft of the drive motor 60, and the gear 61 meshes with the external gear ring for transmission.
[0048] In this embodiment, the drive motor 60 is a vacuum servo motor or a vacuum stepper motor.
[0049] The working principle or operation process of this utility model is as follows:
[0050] When depositing boron-doped diamond powder, the ring seat 10 is bolted to the worktable of the deposition equipment. The wires pass through the holes on the worktable and extend into the space below the worktable, which facilitates connection to the power supply or controller. The holes on the worktable are sealed with sealant.
[0051] In use, start the drive motor 60, which drives the gear 61 to rotate. The rotation of the gear 61 drives the internal gear ring 50 to rotate, which in turn drives the rotating ring 20 to rotate, thereby driving the vibrating container 30 to rotate. Start the vibrator 40, and the bottom wall of the vibrating container 30 will vibrate.
