Abstract
Description
Technical Field

[0002] In the production of silicon wafers for semiconductors, silicon ingots are slit into wafers of a certain thickness using diamond wire and a cutting fluid. Therefore, the performance of the cutting fluid has a crucial impact on the efficiency, precision, and lifespan of the diamond wire cutting process.

Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0059] like Figures 1 to 5 As shown, an embodiment of this utility model provides a nano-silica particle grinding device, comprising:
[0060] Grinding tube 1;
[0061] The first layer of the grinding assembly has one end inserted into the grinding tube 1 and is rotatably connected to the grinding tube 1;
[0062] The outer wall of the second grinding assembly is connected to the inner wall of the grinding tube 1, and it is sleeved on the first grinding assembly.
[0063] The third grinding component is fitted onto the first grinding component and is fixedly connected to the other end of the grinding tube 1;
[0064] The top surface of the support base is fixedly connected to the outer wall of the third-layer grinding assembly via connecting column 54.
[0065] In this embodiment of the invention, during use, the operator places the nano-silica material into the first grinding component for initial grinding. Then, the material after initial grinding is fed into the second grinding component for further grinding, making the nano-silica material even finer. The material then falls naturally into the third grinding component, where it is ground once more to ensure that the nano-silica material is ground into the required particles. Finally, the material falls onto the support base through the third grinding component and is collected.
[0066] like Figures 1 to 5 As shown, the grinding tube 1 includes:
[0067] The first feeding hole 11 is opened on the outer wall of the grinding tube 1 and is fixedly connected to the first layer of grinding assembly;
[0068] Rotation hole 12 is formed on the outer wall of grinding tube 1 and is connected to the second grinding assembly.
[0069] like Figures 1 to 5 As shown, the first layer polishing assembly includes:
[0070] The connecting tube 21 has one end covering the first feeding hole 11 and is fixedly connected to the outer wall of the grinding tube 1;
[0071] The bottom surface of the material box 22 is fixedly connected to the other end of the connecting pipe 21, and a second feeding hole 221 is provided on the bottom surface of the material box 22.
[0072] The outer wall of the first rotating disk 23 is fixedly connected to the inner wall of one end of the grinding tube 1, and the first rotating disk 23 is provided with a first rotating hole 231.
[0073] The first rotating shaft 24 is located inside the grinding tube 1, and one end of it passes through the first rotating hole 231 to extend out of the first rotating disk 23;
[0074] The output end of the first motor 25 is fixedly connected to one end of the first rotating shaft 24 through the first rotating hole 231 that passes through the top surface of the first rotating disk 23.
[0075] The first conical block 26 is sleeved on the first rotating shaft 24, and the first conical block 26 has a second rotating hole 261.

[0079] In this embodiment of the invention, during use, the operator first places the nano-silica material into the material box 22, and then enters the grinding tube 1 through the connecting pipe 21. The first motor 25 is started, causing the first rotating shaft 24 to rotate, which in turn drives the first grinding ring 27 to rotate. The material falling into the grinding tube 1 is then ground for the first time through the cooperation of the first grinding ring 27 and the second grinding ring 28. The first conical block 26 also rotates with the first grinding ring 27, which can prevent the material in the grinding tube 1 from accumulating between the first grinding ring 27 and the first rotating disk 23, thereby improving the grinding efficiency. Finally, the ground material is fed into the second grinding component through the feeding component for the second grinding.
[0080] like Figures 1 to 5 As shown, the feeding assembly includes:
[0081] The first rotating ring 291 is sleeved on the first rotating shaft 24 and fixedly connected to the first rotating shaft 24, and the top surface of the first rotating ring 291 is connected to the bottom surface of the first grinding ring 27.
[0082] The inclined plate 292 is provided in multiple sets. One end of the inclined plate 292 is fixedly connected to the outer wall of the first rotating ring 291, and the other end is slidably connected to the inner wall of the grinding tube 1.
[0083] The first drain plate 293 is located at the bottom of the first rotating ring 291 and is sleeved on the first rotating shaft 24 and rotatably connected to the first rotating shaft 24. The first drain plate 293 has multiple sets of first drain holes 2931.
[0084] In this embodiment of the invention, multiple sets of inclined long plates 292 are provided and are distributed circumferentially on the outer wall of the first rotating ring 291. The inclined surface of the inclined long plates 292 corresponds to the first drain plate 293, which helps to collect the material that falls on the first drain plate 293 and can also speed up the material from the first drain plate 293 into the second grinding assembly. During the operation of the device, the rotation of the first rotating shaft 24 also drives the first rotating ring 291 to rotate, which causes the inclined long plates 292 on the first rotating ring 291 to also make circumferential motion, thereby collecting the material that falls on the first drain plate 293 and speeding up the material from the first drain plate 293 into the second grinding assembly.
[0085] like Figures 1 to 5 As shown, the second-layer grinding assembly includes:
[0086] The second conical block 31 is located at the bottom of the first drain plate 293 and is sleeved on the first rotating shaft 24;
[0087] The second grinding ring 32 is sleeved on the first rotating shaft 24 and fixedly connected to the first rotating shaft 24, and fixedly connected to the bottom of the second conical block 31;
[0088] The inclined ring block 33 has its outer wall fixedly connected to the inner wall of the grinding tube 1, and the bottom of the inclined ring block 33 is provided with a first sliding ring block 331;
[0089] The top surface of the second wear gear 34 is rotatably connected to the bottom surface of the inclined ring block 33, and the top surface of the second wear gear 34 is provided with a first sliding groove 341;
[0090] The top surface of the first support ring 35 is rotatably connected to the bottom surface of the second grinding gear 34, and the outer wall is fixedly connected to the inner wall of the grinding tube 1.
[0091] Support block 36, one end of which is fixedly connected to the outer wall of grinding tube 1;
[0092] The second rotating shaft 37 is rotatably connected at one end to the top surface of the support block 36;
[0093] The first gear 38 is sleeved on the second rotating shaft 37 and fixedly connected to the second rotating shaft 37, and meshes with the second grinding gear 34;
[0094] The output end of the second motor 39 is fixedly connected to the other end of the second rotating shaft 37.
[0095] In this embodiment of the invention, the outer wall of the second grinding ring 32 is circumferentially distributed with multiple sets of inclined semi-cylinders; the inner wall of the second grinding gear 34 is circumferentially distributed with multiple sets of inclined semi-cylinders, which can grind the material by interacting with the inclined semi-cylinders on the outer wall of the second grinding ring 32; during operation of the device, the rotation of the first rotating shaft 24 also drives the second grinding ring 32 to rotate, and at the same time, the second motor 39 is started to drive the second rotating shaft 37 to rotate, which in turn drives the first gear 38 to rotate, thereby driving the second grinding gear 34 to slide along the first sliding ring block 331 through the first sliding groove 341, so that the rotation direction of the second grinding ring 32 and the second grinding gear 34 is opposite, thereby enabling the material that falls into it to be ground again, further ensuring that the material is ground thoroughly.
[0096] like Figures 1 to 5 As shown, the third-layer grinding assembly includes:
[0097] A hemispherical tube 41 is fixedly connected at one end to the other end of the grinding tube 1, and a second material leakage hole 411 is provided at the other end of the hemispherical tube 41.
[0098] An arc-shaped grinding block 42 is located inside a hemispherical tube 41 and is sleeved on a first rotating shaft 24 and fixedly connected to the first rotating shaft 24. The arc-shaped grinding block 42 has a third rotating hole 421.
[0099] The second drain plate 43 is sleeved on the first rotating shaft 24 and rotatably connected to the first rotating shaft 24. Its outer wall is fixedly connected to the inner wall of the hemispherical tube 41. The second drain plate 43 has multiple sets of third drain holes 431.
[0100] In this embodiment of the invention, during the operation of the device, the rotation of the first rotating shaft 24 also drives the arc-shaped grinding block 42 to rotate, thereby grinding the material that falls onto the second drain plate 43. At the same time, due to the special nature of the third discharge hole 431, only nano-silica particles that meet the specifications can fall onto the support base. Unqualified particles can also pass through the third discharge hole 431 under the grinding of the arc-shaped grinding block 42, thereby ensuring that nano-silica particles that meet the specifications are obtained.
[0101] like Figures 1 to 5 As shown, the support base includes:
[0102] The support plate 51 is fixedly connected to the outer wall of the hemispherical tube 41 via the connecting column 54;
[0103] The first rotating base 52 is sleeved on the other end of the first rotating shaft 24 and rotatably connected to the first rotating shaft 24, and the bottom surface of the first rotating base 52 is fixedly connected to the top surface of the support plate 51.
[0104] The receiving tube 53 is fixedly connected at one end to the top surface of the support plate 51.
[0105] In this embodiment of the invention, the compliant nano-silica particles fall into the receiving tube 53 through the second leakage hole 411, ensuring the collection of materials and preventing material loss.
[0106] In one specific implementation: First, the operator places the nano-silica material into the material box 22, and then it enters the grinding tube 1 through the connecting pipe 21. The first motor 25 is started, causing the first rotating shaft 24 to rotate, which in turn drives the first grinding ring 27 to rotate. The material falling into the grinding tube 1 undergoes its first grinding through the interaction of the first grinding ring 27 and the second grinding ring 28. The first conical block 26 also rotates along with the first grinding ring 27, preventing material accumulation between the first grinding ring 27 and the first rotating disk 23, thus improving grinding efficiency. Finally, the rotation of the first rotating shaft 24 also drives the first rotating ring 291 to rotate, thereby causing the material on the first rotating ring 291 to... The inclined plate 292 also follows the circular motion, thereby collecting the material that falls onto the first strainer 293 and accelerating the material to fall from the first strainer 293 into the space between the second grinding ring 32 and the second grinding gear 34. Furthermore, the rotation of the first rotating shaft 24 also drives the second grinding ring 32 to rotate. At the same time, the second motor 39 is started to drive the second rotating shaft 37 to rotate, which in turn drives the first gear 38 to rotate. The first gear 38 then drives the second grinding gear 34 to slide along the first sliding ring block 331 through the first sliding groove 341, so that the rotation direction of the second grinding ring 32 and the second grinding gear 34 is opposite, thereby enabling the material that has fallen into it to be ground again, further ensuring that the material is ground thoroughly.
[0107] Finally, the rotation of the first rotating shaft 24 also drives the arc-shaped grinding block 42 to rotate, thereby grinding the material that falls onto the second drain plate 43. At the same time, due to the special nature of the third discharge hole 431, only nano-silica particles that meet the specifications can fall into the receiving tube 53. Unqualified particles can also pass through the third discharge hole 431 under the grinding of the arc-shaped grinding block 42, thus ensuring that nano-silica particles that meet the specifications are obtained.
[0108] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
