Description

Technical Field

[0001] The utility model relates to the technical field of ring polishing machines, in particular to a polishing device for ceramic substrates. Background Art

[0002] A ring polishing machine is a device designed based on the annular continuous polishing method. Annular continuous polishing is a kind of replication polishing. The correction disk adjusts the asphalt glue disk, and the asphalt glue disk then polishes the workpiece to be processed. Therefore, the core of annular continuous polishing is how to obtain a high-precision asphalt polishing mold and polish under the condition of constant component conditions to obtain high-precision components.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.

[0024] Please refer to Figure 1-6 , the present utility model provides a ceramic substrate polishing device, including a body 1, a main grinding disc 2 and a first motor 3. The main grinding disc 2 is concentrically and rotatably arranged inside the body 1. The first motor 3 is installed below the body 1. The main grinding disc 2 is connected to the output end of the first motor 3. A base 4 is fixedly arranged on the side of the body 1. A connecting arm 5 is horizontally movably arranged on the base 4. One end of the connecting arm 5 is provided with a correcting disc 6. A reciprocating driving mechanism is arranged between the connecting arm 5 and the base 4. A cleaning mechanism for cleaning the side of the main grinding disc 2 is also arranged on the base 4.

[0025] Please refer to Figure 1 and 2, in this solution, the connection mode between the correction disk 6 and the connecting arm 5 is connected according to the connection mode in the prior art, and a pneumatic clamping mechanism in the prior art is additionally arranged on the correction disk 6 to fix the workpiece. The reciprocating driving mechanism can drive the workpiece to perform horizontal reciprocating motion on the surface of the main grinding disk 2. Since the main grinding disk 2 rotates continuously, the actual polishing method for the workpiece at this time is the rotation of the main grinding disk 2 and the horizontal reciprocating motion of the main grinding disk 2 relative to the workpiece, thereby increasing the polishing trajectory of the workpiece to improve the polishing effect of the workpiece. At the same time, the cleaning mechanism can clean the side surface of the main grinding disk 2 during the rotation of the main grinding disk 2 without stopping the rotation of the main grinding disk 2, achieving the effect of improving the polishing efficiency of the workpiece.

[0026] The reciprocating driving mechanism includes a second motor 7, a main shaft 8, a swing arm 9, a driving shaft 10, and a chute 11. The second motor 7 is fixed below the base 4. The main shaft 8 is rotatably arranged on the surface of the base 4, and the bottom of the main shaft 8 is connected to the output end of the second motor 7. The swing arm 9 is fixed to the top of the main shaft 8. The driving shaft 10 is fixed to the top of the swing arm 9. The chute 11 is arranged on the surface of the connecting arm 5. The driving shaft 10 is slidably arranged in the chute 11. A support seat 20 is fixedly arranged on the top of the base 4. The connecting arm 5 is slidably arranged on the top of the support seat 20. A guiding protrusion 21 is arranged on the surface of the support seat 20. A guiding groove 22 is arranged on the side surface of the connecting arm 5. The guiding protrusion 21 is slidably arranged in the guiding groove 22.

[0027] Please refer to Figure 3 and 4 , the second motor 7 can drive the main shaft 8 to rotate. At this time, the main shaft 8 can drive the driving shaft 10 to revolve through the swing arm 9. At this time, the driving shaft 10 can form a crank-rocker structure with the chute 11 to realize the horizontal reciprocating drive of the connecting arm 5. At this time, the connecting arm 5 can reciprocate on the top of the support seat 20, and then drive the workpiece to perform synchronous horizontal reciprocating motion through the correction disk 6 and the pneumatic clamping mechanism.

[0028] The cleaning mechanism includes a brush 12 and a frame 13. The brush 12 is detachably mounted on the surface of the frame 13. One side of the brush 12 is in contact with the side surface of the main grinding disk 2. The frame 13 is connected to the base 4 through a vertical reciprocating mechanism. A limiting groove 23 is arranged on the side surface of the base 4. A limiting protrusion 24 is fixedly arranged on the surface of the frame 13. The limiting protrusion 24 is slidably arranged in the limiting groove 23. A T-shaped groove 25 is arranged on the surface of the brush 12. A T-shaped protrusion 26 is fixedly arranged on the surface of the frame 13. The T-shaped protrusion 26 is slidably arranged in the T-shaped groove 25.

[0029] Please refer to Figure 3 , 5With respect to FIGS. 5 and 6, since the main grinding disc 2 rotates continuously, when the brush 12 moves vertically in a reciprocating manner, the brush 12 can uniformly clean the side surface of the main grinding disc 2, thereby sweeping off the debris adhering to the side surface of the main grinding disc 2 and making it fall into the machine body 1 for subsequent unified collection. In this process, the brush 12 is driven by the frame 13 to move vertically in a reciprocating manner on the surface of the base 4. When the frame 13 moves, it can drive the limit protrusion 24 to move synchronously inside the limit groove 23, and the movement process of the frame 13 and the brush 12 is limited by the limit protrusion 24 and the limit groove 23.

[0030] It should be noted that the brush 12 also needs to be cleaned after long-term use. In this embodiment, the brush 12 and the frame 13 are set as a detachable connection structure. By horizontally pushing the brush 12, the brush 12 can drive the T-shaped groove 25 to move on the surface of the T-shaped protrusion 26. When the T-shaped groove 25 is separated from the surface of the T-shaped protrusion 26, the disassembly of the brush 12 and the frame 13 can be realized, so as to facilitate the cleaning of the brush 12.

[0031] The vertical reciprocating mechanism includes a traction shaft 14, a semi-gear 15, gear teeth 16, a limit rod 17 and a spring 18. The traction shaft 14 is rotatably arranged on the surface of the base 4 and is connected to the main shaft 8 through a transmission member. The semi-gear 15 is fixed on the surface of the traction shaft 14. The gear teeth 16 are arranged on the surface of the frame 13 and are meshed with the semi-gear 15. The bottom end of the limit rod 17 is fixed on the frame 13, and the top end of the limit rod 17 is slidably arranged inside the base 4. The spring 18 is fixed between the frame 13 and the base 4, and the spring 18 is sleeved on the surface of the limit rod 17. The transmission member is two meshing bevel gears 19, one of the bevel gears 19 is fixed on the surface of the main shaft 8, and the other bevel gear 19 is fixed on the surface of the traction shaft 14.

[0032] Please refer to Figure 5 and 6, when the main shaft 8 rotates, it can drive the traction shaft 14 to rotate through two meshing bevel gears 19. When the traction shaft 14 rotates, it can drive the half gear 15 to rotate synchronously. When the half gear 15 rotates, it can drive the frame 13 to move upward through the teeth 16. At this time, the frame 13 can drive the brush 12 to move synchronously, so that the brush 12 moves from the bottom to the top of the side of the main grinding disc 2. During this process, the frame 13 can drive the limiting rod 17 to move upward. Since the distance between the frame 13 and the base 4 is shortened, the spring 18 is also in a compressed state. As the half gear 15 continues to rotate, the half gear 15 will separate from the teeth 16. At this time, the brush 12 just reaches the top of the side of the main grinding disc 2. After the spring 18 releases energy, it drives the frame 13 to reset, and the frame 13 can drive the brush 12 to reset, so that the brush 12 moves in the reverse direction, from the top of the side of the main grinding disc 2 to the bottom. During the above process, the main grinding disc 2 always remains in a rotating state, so that the brush 12 can comprehensively clean the side of the main grinding disc 2.
