[0002] Planetary wheels are fixtures used in the polishing processes of various flat surfaces such as glass, lenses, silicon wafers, and hard drives. They are also known as polishing jigs or polishing pads.

[0003] A search revealed an existing patent (publication number: CN221364326U) that discloses an anti-chipping planetary wheel for double-sided polishing of lithium tantalate wafers. The planetary wheel includes a main body with gears on its outer periphery. The main body has a first drain hole and a second drain hole, the first drain hole being located in the middle of the main body and the second drain holes located on either side of a placement hole. The main body also has a protective ring, and a protective ring is located inside the placement hole. A limiting groove is provided at the connection between the protective ring and the placement hole. An indicator hole is located between the first drain hole and the placement hole. By optimizing the planetary wheel material and structure, the patent solves the problems of wafer chipping, scratching of processing tools, and low production efficiency caused by existing planetary wheels during polishing. By fixing protective rings of different sizes to the planetary wheel, it can be used for polishing 4-inch, 6-inch, and 8-inch wafers respectively.

[0004] It allows for the convenient placement of different polishing materials by changing the protective rings of different sizes. However, it has its drawbacks. Changing the protective rings requires storing many other protective rings, which increases costs. In addition, it lacks a dustproof mechanism, which causes dust to fly during polishing and pollute the working environment. Utility Model Content

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a planetary wheel with a dustproof structure, comprising a planetary wheel body, the top of the planetary wheel body having a plurality of vertically penetrating placement holes, the bottom of the placement holes having an annular groove, a sealing ring being rotatably connected inside the annular groove, two dust suction holes being formed on the inner sidewall of the placement holes, the dust suction holes being connected to the annular groove, and a connecting pipe being fixed to the bottom of the sealing ring.

[0007] Preferably, the placement hole is provided with a limiting mechanism, which includes multiple limiting blocks. The outer side wall of each limiting block has a movable groove and two connecting rods are rotatably connected inside. The other ends of the two connecting rods are respectively fixed with a rotating block and a moving block. The inner side wall of the placement hole has an annular mounting groove, and the top and bottom of the rotating block are rotatably connected to the upper and lower inner surfaces of the annular mounting groove, respectively.

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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a planetary wheel with a dustproof structure, including a planetary wheel body 7. The top of the planetary wheel body 7 is provided with a plurality of vertically penetrating placement holes 2. The bottom of the placement holes 2 is provided with an annular rotating groove 17. A sealing ring 10 is rotatably connected inside the annular rotating groove 17. Two dust suction holes 9 are provided on the inner sidewall of the placement holes 2. The dust suction holes 9 are connected to the annular rotating groove 17. A connecting pipe 12 is fixed to the bottom of the sealing ring 10, so that dust can be sucked up during polishing.

[0023] Furthermore, the placement hole 2 is equipped with a limiting mechanism 6, which includes multiple limiting blocks 3. Two connecting rods 4 are rotatably connected to the outer side wall of each limiting block 3 via a movable groove 11. A rotating block 16 and a moving block 15 are respectively fixed to the other ends of the two connecting rods 4. An annular mounting groove 5 is provided on the inner side wall of the placement hole 2. The top and bottom of the rotating block 16 are rotatably connected to the upper and lower inner surfaces of the annular mounting groove 5, respectively. This allows the distance between the limiting blocks 3 to be adjusted according to the size of the polishing material, facilitating the placement of the polishing material. The top of the planetary wheel body 7 is located on the outer side of the placement hole 2. There are multiple arc-shaped through slots 13. A connecting block 14 is fixed to the top of the moving block 15. Multiple rotating rings 1 are provided above the planetary wheel body 7. The top of the connecting block 14 passes through the arc-shaped through slot 13 and is rotatably connected to the bottom of the rotating ring 1, so that multiple moving blocks 15 can move simultaneously. A fastening screw 8 is provided inside the rotating ring 1. The bottom end of the fastening screw 8 passes through the rotating ring 1 and is screwed to one of the connecting blocks 14, so that the rotating ring 1 can be fixed. The limiting block 3 is made of rubber, which can protect the polished material. A horizontal lever is provided on the top of the fastening screw 8, which makes it convenient to manually rotate the fastening screw 8.

[0024] During operation, the rotating ring 1 is rotated according to the size of the polishing materials such as glass, lenses, silicon wafers, and hard drives. The rotating ring 1 moves the connecting block 14 and the moving block 15. The movement of the moving block 15 causes the two connecting rods 4 to close. The closing of the connecting rods 4 causes the limiting block 3 to move. This allows multiple limiting blocks 3 to close. Adjusting the distance between the limiting blocks 3 facilitates the placement of polishing materials. The connecting pipe 12 is connected to a suction pipe and a fan. When polishing various flat surfaces such as glass, lenses, silicon wafers, and hard drives, the fan is turned on, and the suction pipe generates suction. In this way, the dust suction hole 9 can suck the polishing dust into the annular rotating groove 17 and then discharge it from the connecting pipe 12 to prevent dust from scattering.
