Description

Technical Field

[0001] This invention relates to the field of polishing disc technology, specifically, to a high-low tooth mixed-type polishing disc brush. Background Technology

[0002] In the 3C metal polishing and glass polishing industry, the shapes of product workpieces are diverse. When mechanically polishing spherical, elliptical, or other product workpieces with large curvature surfaces, polishing disc brushes are required. However, existing polishing disc brushes have uniform brush tooth height. Due to the structural limitations of polishing disc brushes, multi-axis equipment is often used to polish and remove the workpiece surface from multiple angles. This makes the polishing process complex and results in low polishing efficiency and low yield. Summary of the Invention

[0003] The purpose of this invention is to design a high-low tooth mixed polishing disc brush to solve the problems of low polishing efficiency and low yield.

[0004] This invention is achieved through the following technical solution:

[0005] A high-low tooth mixed polishing disc brush includes a brush disc and flexible first and second annular brushes; the top surface of the brush disc is connected to a plurality of the first and second annular brushes, all of which are concentrically arranged and alternately arranged radially; the tip of the first annular brush is closer to the axial distance from the brush disc than the tip of the second annular brush.

[0006] With the above-described structure, a first annular brush and a second annular brush of different heights are simultaneously arranged on the same surface of the brush disk. The first and second annular brushes are concentric and alternately arranged radially, resulting in brush teeth that are staggered in height along the radial direction. This allows the first and second annular brushes to work together radially to provide a certain degree of coverage to the bottom and sides of the workpiece during mechanical polishing. This enables simultaneous polishing of the sides and bottom of the workpiece in a single process without changing the brush disk orientation. This simplifies the polishing process and increases efficiency. Furthermore, simultaneous polishing of the sides and bottom of the workpiece ensures uniform and stable removal of material across the workpiece, resulting in better polishing effects and improved yield.

[0007] In addition, there is a height difference between adjacent first and second annular brushes in the radial direction. The existence of this height difference can help the polishing fluid to be stored between the adjacent first and second annular brushes, so that both the first and second annular brushes and the polishing part of the workpiece can obtain more polishing fluid, thereby better ensuring the polishing effect on the workpiece and improving the yield.

[0008] In addition, during polishing, the workpiece and the high-low tooth mixed polishing disc brush rotate independently. The centrifugal force causes the polishing liquid to adhere evenly to the workpiece. When the workpiece passes through the adjacent first and second annular brushes, it exerts a downward pressure on the first and second annular brushes. Since there is a height difference between the adjacent first and second annular brushes, some of the polishing liquid on the workpiece can fall back directly between the adjacent first and second annular brushes and be stored well, reducing the waste and loss of polishing liquid.

[0009] To further improve the implementation of this invention, the following structure is specifically adopted: the first annular brush is configured as a toothed ring structure, including a plurality of short brush teeth arranged in a circumferential array, the roots of the short brush teeth being fixedly connected to the brush disk; the second annular brush is configured as a toothed ring structure, including a plurality of tall brush teeth arranged in a circumferential array, the roots of the tall brush teeth being fixedly connected to the brush disk.

[0010] When the above-mentioned structure is adopted, both the first and second annular brushes are composed of independent brush teeth arranged in a circumferential row. In this way, each annular brush provides multiple independently moving brush teeth. The independent brush teeth have good forced deformation ability and can follow and fit the workpiece in a timely and effective manner during the workpiece position change, so as to better wrap the workpiece in different positions, ensure the contact area, obtain better polishing effect, and improve the yield.

[0011] To further improve the implementation of this invention, the following configuration is adopted: the short brush teeth are configured as flat-topped teeth.

[0012] When the above-mentioned structure is adopted, the flat-topped short brush teeth have a large area and good axial support at the tooth tip. When the workpiece is pressed down on the top of the short brush teeth, a large contact surface and good support can be guaranteed to obtain better cutting ability. This allows the workpiece surface to be cut quickly and improves polishing efficiency.

[0013] To further improve the implementation of this invention, the following structure is specifically adopted: the inner surface of the short brush teeth is configured as an inner arc surface that is curved in the circumferential direction.

[0014] When the above-mentioned structure is adopted, the inner side of the first annular brush will form a relatively regular arc-shaped wall, which can facilitate the circumferential flow of polishing fluid, improve the flow efficiency of polishing fluid stored inside the first annular brush, and promote a more uniform distribution of polishing fluid to ensure the polishing effect.

[0015] To further improve the implementation of this invention, the following structure is specifically adopted: the outer surface of the short brush teeth is configured as an outer arc surface that is curved in the circumferential direction.

[0016] When the above-mentioned structure is adopted, the outer surface of the first annular brush will form a relatively regular arc-shaped wall, which can facilitate the circumferential flow of polishing fluid, improve the flow efficiency of polishing fluid stored on the outside of the first annular brush, and promote a more uniform distribution of polishing fluid to ensure the polishing effect.

[0017] To further improve the implementation of this invention, the following structure is specifically adopted: the thickness of the tooth tip of the short brush tooth gradually increases in the circumferential direction from the tooth tip to the tooth root.

[0018] When the above-mentioned structure is adopted, in the first annular brush, the gap formed between two adjacent short brush teeth is larger at the top and smaller at the bottom, which can facilitate the radial upward flow of polishing liquid moving to the upper part of the first annular brush and facilitate the better storage of polishing liquid moving to the lower part of the first annular brush.

[0019] To further improve the implementation of this invention, the following configuration is adopted: the high brush teeth are configured as pointed teeth.

[0020] When the above-mentioned structure is adopted, the high brush teeth with pointed tips have lower strength at the top, which is conducive to the bending of the high brush teeth. When the workpiece passes through the high brush teeth, the high brush teeth can follow the bending of the workpiece well and stick to the surface of the workpiece, thereby polishing a larger arc surface on the workpiece and improving polishing efficiency.

[0021] To further improve the implementation of this invention, the following structure is specifically adopted: the inner surface of the high brush teeth is configured as an inner arc surface that is curved in the circumferential direction.

[0022] When the above-mentioned structure is adopted, the high brush teeth can make more contact with the workpiece surface through the inner arc surface when following the workpiece outward, thereby polishing the larger arc surface on the workpiece and improving the polishing efficiency. In addition, the inner side of the second annular brush will form a relatively regular arc wall, which can facilitate the circumferential flow of polishing liquid, improve the flow efficiency of polishing liquid stored inside the second annular brush, and promote a more uniform distribution of polishing liquid to ensure the polishing effect.

[0023] To further improve the implementation of this invention, the following structure is specifically adopted: the outer surface of the high brush tooth is configured as an outer arc surface or an inner arc surface that is curved in the circumferential direction.

[0024] When the above-described structure is adopted, if the outer surface of the high brush teeth is set as an outer arc surface that curves circumferentially, the outer surface of the second annular brush will form a more regular arc-shaped wall, which facilitates the circumferential flow of polishing fluid, improves the flow efficiency of polishing fluid stored on the outside of the second annular brush, and promotes a more uniform distribution of polishing fluid to ensure polishing effect. If the outer surface of the high brush teeth is set as an inner arc surface that curves circumferentially, the high brush teeth can make more contact with the workpiece surface through the outer arc surface when following the workpiece inward, thereby polishing a larger arc surface on the workpiece and improving polishing efficiency.

[0025] To further improve the implementation of this invention, the following structure is specifically adopted: the thickness of the tooth tip of the high brush tooth gradually increases in the circumferential direction from the tooth tip to the tooth root.

[0026] When the above-described structure is adopted, the gap between two adjacent high brush teeth in the second annular brush is wider at the top and narrower at the bottom. This facilitates the radial upward flow of polishing fluid moving to the upper part of the second annular brush, while the polishing fluid moving to the lower part of the second annular brush is better stored. At the same time, the high brush teeth of this structure also have better bending ability and can better follow the deformation of the workpiece.

[0027] To further improve the implementation of this invention, the following structure is specifically adopted: the two circumferential sides of the high brush tooth tip are configured as outer arc surfaces.

[0028] To further improve the implementation of the present invention, the following configuration structure is specifically adopted: in the first annular brush row, the roots of adjacent short brush teeth are in close contact with each other circumferentially; in the second annular brush row, the roots of adjacent tall brush teeth are in close contact with each other circumferentially.

[0029] When the above-mentioned structure is adopted, the first and second annular brushes will be able to provide more independent brush teeth on a brush disk of a certain size, so as to obtain better polishing efficiency and effect and improve the yield.

[0030] To further improve the implementation of the present invention, the following configuration structure is specifically adopted: In the first annular brush, two adjacent short brush teeth form a first gap between their tips for the passage of polishing liquid; in the second annular brush, two adjacent tall brush teeth form a second gap between their tips for the passage of polishing liquid above the brush disk; the bottom of the second gap is greater than the bottom of the first gap in terms of the axial distance from the top of the brush disk.

[0031] When the above-mentioned structure is adopted, the bottom height of the groove of the first annular brush is lower than the bottom height of the groove of the second annular brush. In this way, the polishing liquid can be better stored between the adjacent first and second annular brushes.

[0032] To further improve the implementation of this invention, the following structure is specifically adopted: the top surface of the brush plate is provided with multiple annular mounting grooves, and the roots of the short brush teeth and the tall brush teeth are inserted into the corresponding mounting grooves and fixed.

[0033] When the above-mentioned structure is adopted, the brush disc can provide certain support for the roots of the short and tall brush teeth through the groove wall of the mounting slot, which can improve the deformation resistance of the short and tall brush teeth, generate greater contact force with the workpiece surface, improve polishing efficiency, and also make the short and tall brush teeth more firmly connected to the brush disc, thus increasing the life of the high and low tooth mixed polishing disc brush.

[0034] To further improve the implementation of the present invention, the following configuration structure is adopted: at least one first annular brush is provided, at least two second annular brushes are provided, and, in the radial direction, one first annular brush is sandwiched between two adjacent second annular brushes.

[0035] When the above-mentioned structure is adopted, the high and low tooth mixed polishing disc brush will inevitably form an annular groove between one or two adjacent second annular brushes, which can effectively store polishing fluid. This allows the polishing fluid to have good fluidity while effectively reducing waste and loss of polishing fluid.

[0036] To further improve the implementation of this invention, the following structure is adopted: a through hole is provided in the center of the brush disk, and the first annular brush and the second annular brush are arranged around the through hole.

[0037] When the above-described structure is used, the central hole of the brush disc is used to avoid the unique structure of the device, allowing the brush disc to be fixed to the device.

[0038] To further improve the implementation of this invention, the following structure is specifically adopted: the brush disk is configured as a flexible component.

[0039] When the above-mentioned structure is adopted, the flexible brush disc has good deformation ability. When the brush disc has a central hole, the brush disc can be deformed to one side about the central hole when using a high-low tooth mixed polishing disc brush alone, so as to better fit the surface of the spherical workpiece and obtain a larger contact area, thereby improving the individual polishing of the spherical workpiece.

[0040] To further improve the implementation of the present invention, the following structure is adopted: multiple felts are connected to the bottom surface of the brush disk, and all the felts are arranged equidistantly along the circumference of the first annular brush.

[0041] The present invention has the following advantages and beneficial effects:

[0042] In this invention, a first annular brush and a second annular brush of different heights are simultaneously arranged on the same surface of the brush disk. The first and second annular brushes are concentric and alternately arranged radially, resulting in brush teeth that are staggered in height along the radial direction. Thus, when mechanically polishing workpieces with large curvature surfaces, the first and second annular brushes can cooperate radially to provide a certain degree of coverage to the bottom and sides of the workpiece. This allows for simultaneous polishing of the sides and bottom of the workpiece in a single process without changing the brush disk orientation. This simplifies the polishing process and increases polishing efficiency. Furthermore, simultaneously polishing the sides and bottom of the workpiece ensures that the amount of material removed from each part of the workpiece is uniform and stable, resulting in better polishing effects and improved yield.

[0043] In addition, there is a height difference between adjacent first and second annular brushes in the radial direction. The existence of this height difference can help the polishing fluid to be stored between the adjacent first and second annular brushes, so that both the first and second annular brushes and the polishing part of the workpiece can obtain more polishing fluid, thereby better ensuring the polishing effect on the workpiece and improving the yield.

[0044] In addition, during polishing, the workpiece and the high-low tooth mixed polishing disc brush rotate independently. The centrifugal force causes the polishing liquid to adhere evenly to the workpiece. When the workpiece passes through the adjacent first and second annular brushes, it exerts a downward pressure on the first and second annular brushes. Since there is a height difference between the adjacent first and second annular brushes, some of the polishing liquid on the workpiece can fall back directly between the adjacent first and second annular brushes and be stored well, reducing the waste and loss of polishing liquid.

[0063] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0064] In the description of this invention, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly, for example, as fixed connections, detachable connections, or integral connections; as mechanical connections or electrical connections; as direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0065] In related technologies, the brush teeth in polishing disc brushes are all at the same height. However, when polishing workpieces, polishing disc brushes need to store an appropriate amount of polishing fluid to cool the workpiece and the workpiece being polished. If the brush teeth are all at the same height, it will be difficult to store the polishing fluid. Brush teeth of uniform height cannot effectively remove material from the sides and bottom of workpieces with large curved surfaces such as spheres, requiring the use of multi-axis equipment to process the workpiece from different angles.

[0066] A high-low tooth mixed-type polishing disc brush solves the problems of low polishing efficiency and low yield, such as... Figures 1-11 As shown, it is specifically configured with the following structure:

[0067] In some embodiments, the high-low tooth mixed polishing disc brush includes a brush disc 1 and a flexible first annular brush 2 and a second annular brush 3.

[0068] The brush 1 can be a disc structure made of polyurethane, polyvinyl chloride and acrylonitrile-butadiene-styrene copolymer.

[0069] Both the first annular brush 2 and the second annular brush 3 are used to cut and remove material from the surface of the workpiece for polishing. The first annular brush 2 and the second annular brush 3 can be structural components made of polyurethane, polyvinyl chloride, and acrylonitrile-butadiene-styrene copolymer. Compared to existing brushes made of felt material, the high-low tooth mixed-type polishing disc brush of this embodiment has a faster workpiece removal speed and a longer lifespan, reducing the frequency of consumable replacements and improving production efficiency.

[0070] refer to Figure 1The top surface of the brush disk 1 is connected to several first annular brushes 2 and second annular brushes 3. The first annular brushes 2 and second annular brushes 3 are fixed to the brush disk 1 according to a certain arrangement rule. All the first annular brushes 2 and second annular brushes 3 are concentrically arranged, and all the first annular brushes 2 and second annular brushes 3 are arranged alternately in the radial direction. In this embodiment, the first annular brushes 2 and the brush disk 1 are also concentric.

[0071] The first annular brush 2 is set approximately perpendicular to the brush disk 1. The axial distance between the top of the first annular brush 2 and the top surface of the brush disk 1 is smaller than the axial distance between the top of the second annular brush 3 and the top surface of the brush disk 1. This is manifested in the form that brush teeth of varying heights are formed on the top surface of the brush disk 1.

[0072] In this embodiment, a first annular brush 2 and a second annular brush 3 of different heights are simultaneously arranged on the same surface of the brush disk 1. The first annular brush 2 and the second annular brush 3 are concentric and alternately arranged radially, so that the brush teeth formed on the brush disk 1 are staggered in height along the radial direction. In this way, when mechanically polishing workpieces with large curvature surfaces, the first annular brush 2 and the second annular brush 3 can cooperate radially to form a certain wrapping effect on the bottom and sides of the workpiece. In one process, the sides and bottom of the workpiece can be polished simultaneously without changing the orientation of the brush disk 1. In this way, the polishing process is simpler and the polishing efficiency is higher. Moreover, polishing the sides and bottom of the workpiece simultaneously can ensure that the amount of material removed from all parts of the workpiece is uniform and stable, resulting in better polishing effect and improved yield.

[0073] In addition, there is a height difference between adjacent first annular brush 2 and second annular brush 3 in the radial direction. The existence of the height difference can help the polishing fluid to be stored between adjacent first annular brush 2 and second annular brush 3, so that the first annular brush 2 and second annular brush 3 and the polishing part of the workpiece can obtain more polishing fluid, so as to better ensure the polishing effect of the workpiece and improve the yield.

[0074] In addition, during polishing, the workpiece and the high and low tooth mixed polishing disc brush rotate independently. The centrifugal force causes the polishing liquid to adhere evenly to the workpiece. When the workpiece passes through the adjacent first annular brush 2 and second annular brush 3, it exerts a downward pressure on the first annular brush 2 and second annular brush 3. Since there is a height difference between the adjacent first annular brush 2 and second annular brush 3, some of the polishing liquid on the workpiece can fall directly back between the adjacent first annular brush 2 and second annular brush 3 and be stored well, reducing the waste and loss of polishing liquid.

[0075] According to some optional embodiments, such as Figure 2 As shown, felt 4 is pre-attached to the bottom surface of brush 1. The quantity of felt 4 is determined according to the size, for example... Figure 2 The felt 4 consists of four pieces, which are arranged equidistantly along the circumference of the first annular brush 2. The arrangement of the felt 4 allows the high and low tooth mixed polishing disc brush to be quickly fixed to the Velcro on the turntable of the equipment, or removed from the turntable. This method is more convenient for assembly and disassembly than fixing it to the turntable with adhesive backing.

[0076] According to some optional embodiments, such as Figure 1 , Figure 2 and Figure 7 As shown, a through-hole 12 is provided at the center of the brush disk 1. The through-hole 12 is mainly used to avoid the protruding structures on the equipment when the high and low tooth mixed polishing disc brush is used. The first annular brush 2 and the second annular brush 3 are arranged around the through-hole 12 with the center as the center. The through-hole 12 of the brush disk 1 is used to avoid the unique structures on the equipment, so that the brush disk 1 can be fixed to the equipment.

[0077] Preferably, the brush disk 1 is configured as a flexible component, giving it good deformability. When using a mixed high-low tooth polishing disk brush alone, the brush disk 1 can cover the workpiece. In this case, the brush disk 1 can deform towards the workpiece side about the central hole 12 to better fit the surface of the spherical workpiece, obtaining a larger contact area and improving the individual polishing of the spherical workpiece.

[0078] According to some optional embodiments, refer to Figure 1 One of the first annular brush 2 and the second annular brush 3 can be configured as a toothed ring structure alone, or both can be configured as toothed ring structures. The latter, as shown in the example... Figure 1 The first annular brush 2 and the second annular brush 3 shown are preferably configured as toothed ring structures. If one of the first annular brush 2 and the second annular brush 3 is configured as a toothed ring structure alone, the other can be configured as an annular structure with a continuous circumferential top.

[0079] The top of the toothed ring-shaped structure has continuous undulations along the axial direction, similar to the structure of a toothed ring.

[0080] When the first annular brush 2 is configured as a toothed ring structure, the first annular brush 2 is composed of multiple short brush teeth 21. All the short brush teeth 21 are arranged in a circumferential array, and the roots of the short brush teeth 21 are fixedly connected to the top surface of the brush disk 1. The short brush teeth 21 can be brush teeth made from a single piece of existing polishing and grinding material, or they can be brush teeth formed by a bundle of multiple existing bristles used for polishing and grinding.

[0081] When the second annular brush 3 is configured as a toothed ring structure, the second annular brush 3 is composed of multiple high brush teeth 31. All the high brush teeth 31 are arranged in a circumferential array, and the roots of the high brush teeth 31 are fixedly connected to the top surface of the brush disk 1. The high brush teeth 31 can be brush teeth made from a single piece of existing polishing and grinding material, or they can be brush teeth formed by a bundle of multiple existing bristles used for polishing and grinding.

[0082] In the preferred configuration of this embodiment, both the first annular brush 2 and the second annular brush 3 are composed of independent brush teeth arranged in a circumferential array. In this way, each annular brush provides multiple independently moving brush teeth. The independent brush teeth have good forced deformation ability and can follow and fit the workpiece in a timely and effective manner during the workpiece position change process, so as to better wrap the workpiece at different positions, ensure the contact area, obtain better polishing effect, and improve the yield.

[0083] According to some optional embodiments, such as Figures 8-11 As shown, the short brush tooth 21 is formed by a first inner side 211 and a first outer side 212 arranged radially front to back, a first circumferential side 213 arranged circumferentially opposite, and a first tooth top surface 214 and a first tooth bottom surface 215 arranged vertically. The tall brush tooth 31 is formed by a second inner side 311 and a second outer side 312 arranged radially front to back, two second circumferential side surfaces 313 arranged circumferentially opposite, and a second tooth top surface 314 and a second tooth bottom surface 315 arranged vertically.

[0084] Based on the first annular brush 2 being configured as a toothed ring structure, the structure of the short brush teeth 21 can be designed to improve their polishing performance on the workpiece. Figure 10 and Figure 11 Taking the high brush tooth 31 shown as an example, for instance:

[0085] According to some optional embodiments, the first annular brush 2 is configured with a toothed ring structure, and the short brush teeth 21 are configured as follows: Figure 10 The flat-topped brush tooth shown has a flat first tooth tip surface 214. The flat-topped short brush tooth 21 provides a large area and good axial support at its tip. When the workpiece presses down on the first tooth tip surface 214 of the short brush tooth 21, it ensures that the first tooth tip surface 214 has a large contact area with the workpiece, providing good support for the workpiece and obtaining good cutting ability. This allows the workpiece surface to be cut quickly, improving polishing efficiency.

[0086] According to some optional embodiments, such as Figure 10 and Figure 11As shown, the first inner surface 211 of the short brush teeth 21 is configured as an inner arc surface that is curved in the circumferential direction. The first inner surface 211 of the first annular brush 2 will form a relatively regular arc wall, which can facilitate the circumferential flow of polishing liquid, improve the flow efficiency of polishing liquid stored inside the first annular brush 2, and promote a more uniform distribution of polishing liquid to ensure polishing effect.

[0087] According to some optional embodiments, such as Figure 10 and Figure 11 As shown, the first outer surface 212 of the short brush teeth 21 is configured as an outer arc surface that is curved in the circumferential direction. The first outer surface 212 of the first annular brush 2 will form a relatively regular arc wall, which can facilitate the circumferential flow of polishing liquid, improve the flow efficiency of polishing liquid stored on the outside of the first annular brush 2, and promote a more uniform distribution of polishing liquid to ensure the polishing effect.

[0088] According to some optional embodiments, such as Figure 10 and Figure 11 As shown, the thickness of the tooth tip of the short brush tooth 21 gradually increases from the tooth tip towards the tooth root, that is, the distance between the two first circumferential side surfaces 213 of the short brush tooth 21 gradually decreases from bottom to top. In the first annular brush 2, the first gap 22 formed between two adjacent short brush teeth 21 and the two opposing first circumferential side surfaces 213 on the two short brush teeth 21 is larger at the top and smaller at the bottom. This facilitates the radial flow of polishing liquid moving to the upper part of the first annular brush 2 through the first gap 22, and also facilitates better storage of polishing liquid moving to the lower part of the first annular brush 2.

[0089] In the above embodiments, the structural design of the short brush teeth 21 can exist alone on the short brush teeth 21, or several of the design structures can exist simultaneously on the short brush teeth 21, or all the design structures in the embodiments can exist simultaneously on the short brush teeth 21. Of course, the preferred configuration is that all the design structures in the embodiments exist simultaneously on the short brush teeth 21, wherein the short brush teeth 21 are... Figure 10 and Figure 11 The structure shown.

[0090] Based on the second annular brush 3 being configured as a toothed ring structure, the structure of the high-quality brush teeth 31 can be designed to improve their polishing performance on the workpiece. Figure 8 and Figure 9 Taking the high brush tooth 31 shown as an example, for instance:

[0091] According to some optional embodiments, the second annular brush 3 is configured as a toothed ring structure, with the high brush teeth 31 configured as pointed teeth. The second tooth tip surface 314 is a generally upwardly convex outer arc surface, wherein the second tooth tip surface 314, formed by the tips of multiple bristles, can be approximated as an outer arc surface. The pointed high brush teeth 31 result in a decrease in the overall strength of their tops towards the upper position, which facilitates the bending of the high brush teeth 31. When the workpiece passes through the high brush teeth 31, the high brush teeth 31 can follow the bending of the workpiece well, so that the second inner side surface 311 or the second outer side surface 312 is in close contact with the workpiece surface, thereby polishing a larger arc surface on the workpiece and improving polishing efficiency.

[0092] According to some optional embodiments, such as Figure 8 and Figure 9 As shown, the second inner surface 311 of the high brush teeth 31 is configured as an inner arc surface that bends circumferentially. When the high brush teeth 31 bend outward with the workpiece, they can make more contact with the workpiece surface through the inner arc surface, thereby polishing a larger arc surface on the workpiece and improving polishing efficiency. In addition, the second inner surface 311 of the second annular brush 3 forms a relatively regular arc wall, which facilitates the circumferential flow of polishing fluid, improves the flow efficiency of polishing fluid stored inside the second annular brush 3, and promotes a more uniform distribution of polishing fluid to ensure polishing effect.

[0093] According to some optional embodiments, such as Figure 8 and Figure 9 As shown, the second outer surface 312 of the high brush tooth 31 is configured as an outer arc surface or an inner arc surface that is curved circumferentially. When the second outer surface 312 of the high brush tooth 31 is configured as an outer arc surface that is curved circumferentially, the outer surface of the second annular brush 3 will form a relatively regular arc-shaped wall, which can facilitate the circumferential flow of polishing fluid, improve the flow efficiency of polishing fluid stored on the outside of the second annular brush 3, and promote a more uniform distribution of polishing fluid to ensure the polishing effect. When the second outer surface 312 of the high brush tooth 31 is configured as an inner arc surface that is curved circumferentially, the high brush tooth 31 can bend inward with the workpiece surface through the outer arc surface, thereby polishing a larger arc surface on the workpiece and improving polishing efficiency.

[0094] According to some optional embodiments, such as Figure 8 and Figure 9As shown, the thickness of the tooth tip of the high brush tooth 31 gradually increases in the circumferential direction from the tooth tip to the tooth root, that is, the distance between the two second circumferential side surfaces 313 of the high brush tooth 31 gradually decreases from bottom to top. In the second annular brush 3, the second gap 32 formed between two adjacent high brush teeth 31 and the two opposing second circumferential side surfaces 313 on the two high brush teeth 31 is larger at the top and smaller at the bottom. This facilitates the radial flow of polishing liquid moving to the upper part of the second annular brush 3 through the second gap 32, and also facilitates better storage of polishing liquid moving to the lower part of the second annular brush 3. At the same time, the high brush tooth 31 with this structure also has better bending ability and can better follow the deformation of the workpiece.

[0095] According to some optional embodiments, such as Figure 8 and Figure 9 As shown, the tips of the high brush teeth 31 are configured as outer arc surfaces on the two second circumferential sides 313 in the circumferential direction.

[0096] In the above embodiments, the structural design of the high brush tooth 31 can exist alone on the high brush tooth 31, or several design structures can exist simultaneously on the high brush tooth 31, or all design structures in all embodiments can exist simultaneously on the high brush tooth 31. Of course, the preferred configuration is that all design structures in all embodiments exist simultaneously on the high brush tooth 31. It should be noted that the outer surface of the high brush tooth 31 is either an outer arc surface in some embodiments or an inner arc surface; the preferred configuration is that the outer surface of the high brush tooth 31 is an outer arc surface. Figure 8 and Figure 9 The structure shown.

[0097] According to some optional embodiments, based on the premise that both the first annular brush 2 and the second annular brush 3 are configured as toothed ring structures, in the first annular brush 2, such as Figure 1 , Figure 4 and Figure 6 As shown, the roots of adjacent short brush teeth 21 are in close contact with each other in the circumferential direction, that is, the bottom of the first circumferential side 213 of one short brush tooth 21 and the bottom of the second circumferential side 313 of another short brush tooth 21 are in contact and pressed against each other.

[0098] Meanwhile, in the second annular brush 3, such as Figure 1 , Figure 4 and Figure 6 As shown, between adjacent high brush teeth 31, their tooth roots are in close contact with each other in the circumferential direction, that is, the second circumferential side 313 of one high brush tooth 31 and the bottom of the second circumferential side 313 of another high brush tooth 31 are in contact and pressed against each other.

[0099] In this embodiment, the first annular brush 2 and the second annular brush 3 can provide more independent brush teeth on the brush disk 1 of a certain size, so as to obtain better polishing efficiency and effect and improve the yield.

[0100] According to some optional embodiments, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in the first annular brush 2, the roots of adjacent short brush teeth 21 are in close contact with each other circumferentially. The thickness of the tips of the short brush teeth 21 gradually increases circumferentially from the tooth tip to the tooth root, forming a first gap 22 that is larger at the top and smaller at the bottom between the tips of two adjacent short brush teeth 21. In the second annular brush 3, the roots of adjacent tall brush teeth 31 are in close contact with each other circumferentially. The thickness of the tips of the tall brush teeth 31 gradually increases circumferentially from the tooth tip to the tooth root, forming a second gap 32 that is larger at the top and smaller at the bottom between the tips of two adjacent tall brush teeth 31. (Reference) Figure 4 The axial distance between the bottom of the second gap 32 and the top of the brush plate 1 is greater than the axial distance between the bottom of the first gap 22 and the top of the brush plate 1, so that the bottom height of the groove of the first annular brush 2 is lower than the bottom height of the groove of the second annular brush 3. In this way, polishing liquid can be better stored between the adjacent first annular brush 2 and second annular brush 3.

[0101] According to some optional embodiments, such as Figure 7 As shown, the top surface of the brush plate 1 has multiple annular mounting slots 11, the number of which is equal to the sum of the number of the first annular brush row 2 and the second annular brush row 3. Figure 6 As shown, the first annular brush 2 and the second annular brush 3 are respectively embedded into the mounting groove 11 and fixed with glue. Specifically, when the first annular brush 2 and the second annular brush 3 are respectively composed of short brush teeth 21 and high brush teeth 31, the short brush teeth 21 and high brush teeth 31 are inserted into the corresponding mounting groove 11 of the brush plate 1 and fixed with glue. Figure 5 and Figure 6 As shown, the roots of the short brush teeth 21 and the tall brush teeth 31 are inserted into the corresponding mounting slots 11 for fixation, and the tips of the short brush teeth 21 and the tall brush teeth 31 protrude from the top surface of the brush disk 1, so that the first gap 22 and the second gap 32 are both located above the top surface of the brush disk 1.

[0102] In this embodiment, the brush disk 1 can provide certain support to the roots of the short brush teeth 21 and the high brush teeth 31 through the groove wall of the mounting groove 11, which can improve the deformation resistance of the short brush teeth 21 and the high brush teeth 31, so as to generate greater contact force with the workpiece surface and improve polishing efficiency. It can also make the short brush teeth 21 and the high brush teeth 31 more firmly connected to the brush disk 1, and improve the life of the high and low tooth mixed polishing disk brush.

[0103] According to some optional embodiments, at least one first annular brush 2 and at least two second annular brushes 3 are provided, and radially, a first annular brush 2 is sandwiched between two adjacent second annular brushes 3. The number of first annular brushes 2 and second annular brushes 3 can be specifically designed according to the workpiece size and polishing requirements. Figure 1 As shown, four first annular brushes 2 and four second annular brushes 3 are set. Three first annular brushes 2 are sandwiched between two adjacent second annular brushes 3 to form a liquid storage tank 5 with three annular rings that can well store polishing liquid.

[0104] Between adjacent first annular brush 2 and second annular brush 3, there is a radial misalignment between the short brush teeth 21 and the adjacent tall brush teeth 31. This misalignment can be irregular, meaning the misalignment between different short brush teeth 21 and adjacent tall brush teeth 31 is not a constant value. This allows the first gap 22 and the second gap 32 to not be arranged in a straight radial line, forming a complex flow channel to better delay the polishing liquid from being thrown off the brush plate 1.

[0105] In this embodiment, the first annular brush 2 and the second annular brush 3 are configured in this numerical relationship, so that the high and low tooth mixed polishing disc brush will inevitably form an annular groove between one or two adjacent second annular brushes 3, which can well store polishing liquid. This annular groove serves as a liquid storage tank 5, which can effectively reduce the waste and loss of polishing liquid while ensuring that the polishing liquid has good fluidity.

[0106] According to some optional embodiments, in the second annular brush 3, all the high brush teeth 31 are also of different heights, but all are higher than the low brush teeth 21. All the high brush teeth 31 are arranged sequentially in the circumferential direction, so that the second annular brush 3 has a undulating trend in the circumferential direction.

[0107] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
