Description

Technical Field

[0001] The utility model relates to the technical field of polishing discs, in particular to a glass polishing brush disc made of polymer materials. Background Art

[0002] Previously, the technological processes mainly used pig hair discs and horse hair discs. The advantages of the existing processes are that animal hairs are elastic, have support, have hair scales to absorb polishing liquid, the toughness of animal hairs is good and not easy to break, and there is a little animal grease, which can play a role in lubrication and brightening. However, the service life of the animal hair brush discs is short. Frequent replacement of the brush discs will increase the cost and the number of loading and unloading operations, increasing the total time required for polishing and thus reducing the polishing efficiency.

[0003] In view of the above situation, in order to overcome the above technical problems, for brittle materials such as glass, ceramics, sapphire, and glass-ceramics, the utility model provides a glass polishing brush disc made of polymer materials, which solves the above technical problems and can be used in equipment such as surface grinding polishing machines and double-sided grinding polishing machines 9B, 13B, 20B, etc. Content of the Utility Model

[0004] The purpose of the utility model is to provide a glass polishing brush disc made of polymer materials. The brush disc body of the polishing brush disc drives the brush to rotate to play a polishing role. The brush is composed of polyurethane polishing leather and polymer sponge, with a longer service life, thus reducing costs, further increasing work efficiency, reducing the overall polishing time, and having a better overall polishing effect.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A glass polishing brush disc made of polymer materials, including a brush disc body and a brush. The brush is installed below the brush disc body. The brush disc body restricts the vertical movement of the polishing brush disc through a limiting groove and further restricts the horizontal rotation of the polishing brush disc through a detachable groove, thereby restricting the position of the polishing brush disc in the polishing machine. The brush evenly contacts the surface of the glass through the arrangement of straight holes in the brush disc body to play a role in uniform grinding.

[0007] The brush disk body is provided with a polishing brush disk, a limiting groove, a detachable groove, a fixing hole, a through hole and a straight hole. The limiting groove penetrates through the periphery of the polishing brush disk. The detachable grooves are arrayed on the periphery of the polishing brush disk. The fixing holes are annularly arrayed between the detachable grooves. The through holes are distributed between the fixing holes and the axis. The through holes are distributed on the brush disk body. The straight hole is formed in the polishing brush disk, and a brush is installed on the straight hole. The limiting hole plays a role in assisting the installation of the polishing brush disk and can also limit the polishing brush disk up and down. The detachable groove can facilitate the installation and disassembly of the polishing brush disk, reducing the time required for installation and disassembly. The fixing hole makes the installation of the polishing brush disk more stable, increasing the stability during polishing. The through hole on the polishing brush disk is used to facilitate the optical film thickness detection device to detect the film thickness value of the wafer, simplifying the structure of the polishing brush disk and making it easy to process.

[0008] The straight holes are annularly arrayed from the inside to the outside along the axis of the polishing brush disk. The regular distribution of the straight holes from the inside to the outside can make the brushes more evenly distributed, and the force during grinding is more uniform.

[0009] The brush is composed of a polyurethane polishing leather and a polymer sponge. The polyurethane polishing leather and the polymer sponge are alternately distributed layer by layer. The polishing leather plays a supporting role and also participates in polishing. The polymer sponge has good water absorption and can fully absorb and store the polishing liquid. Its toughness, tensile strength, fatigue resistance are not in the same order of magnitude as those of pig hair and horse hair.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. The straight holes are annularly arrayed from the inside to the outside along the axis of the brush disk body, making the brushes more evenly distributed and the force more uniform, resulting in a better grinding effect.

[0012] 2. The brush is composed of a polyurethane polishing leather and a polymer sponge. The polishing leather plays a supporting role and also participates in polishing. The polymer sponge has good water absorption and can fully absorb and store the polishing liquid. Its toughness, tensile strength, fatigue resistance are not in the same order of magnitude as those of pig hair and horse hair. Therefore, its service life is 3 - 4 times that of the animal brush disk, with obvious economic benefits. It reduces the downtime for loading and unloading the polishing brush disk, has a better polishing effect, and reduces the polishing time by more than 15%.

[0013] 3. The polyurethane polishing leather and the polymer sponge are alternately distributed layer by layer, ensuring uniformity and making the grinding effect better. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in combination with the specification drawings and specific implementation modes.

[0018] As Figure 1 and Figure 2 shown, the present utility model provides a glass polishing brush disk made of a polymer material, and the technical solution is as follows:

[0019] A glass polishing brush disk made of a polymer material, including a brush disk body 1 and a brush 2. The brush 2 is installed below the brush disk body 1. The brush disk body 1 restricts the vertical movement of the polishing brush disk 1 through the limiting groove 12, and further restricts the horizontal rotation of the polishing brush disk 11 through the detachable groove 13, so as to restrict the position of the polishing brush disk 11 in the polishing machine. The brush 2 uniformly contacts the surface of the glass through the arrangement of the straight holes 16 in the polishing brush disk 11. The brush 2 uniformly rubs against the glass surface, and the polishing effect is better and smoother.

[0020] The brush disk body 1 is provided with a polishing brush disk 11, a limiting groove 12, a detachable groove 13, a fixing hole 14, a through hole 15 and a straight hole 16. The limiting groove 12 penetrates through the periphery of the polishing brush disk 11. The detachable grooves 13 are arranged in an array on the periphery of the polishing brush disk 11. The fixing holes 14 are arranged in an annular array between the detachable grooves 13. The through holes 15 are distributed between the fixing holes 14 and the axis. The through holes 15 are distributed on the polishing brush disk 11. The straight holes 16 are opened on the polishing brush disk 11, and the brush 2 is installed on the straight holes 16. The brush disk body 11 finds the installation position according to the limiting groove 12. The detachable groove 13 is connected to the polishing machine. The fixing hole 14 is combined with the fixing component to fix the polishing brush disk 11. The limiting groove 12 plays a role in assisting the installation of the polishing brush disk 11 and can also limit the up and down position of the polishing brush disk 11. The detachable groove 13 can facilitate the installation and disassembly of the polishing brush disk 1, reducing the time required for installation and disassembly. The fixing hole 14 makes the installation of the polishing brush disk 11 more stable, increasing the stability during polishing. The function of the through holes 15 on the polishing brush disk 11 is to facilitate the optical film thickness detection device to detect the film thickness value of the wafer, simplify the structure of the polishing disk, make it easy to process, improve the yield and productivity, and ensure the quality of the product. The brush 2 is installed on the straight holes 16, and clusters of brushes 2 make the force and the polishing surface more uniform.

[0021] The straight holes 16 are annularly arrayed from the inside to the outside along the axis of the polishing brush disc 11. The regular distribution of the straight holes 16 from the inside to the outside can make the distribution of the brush hairs 2 more uniform, with uniform force during polishing, better polishing effect, and more beautiful appearance of the polishing disc.

[0022] The brush hair 2 is composed of polyurethane polishing leather and polymer sponge. The polyurethane polishing leather and the polymer sponge are alternately distributed layer by layer. The polishing leather plays a supporting role and also participates in polishing. The polymer sponge has good water absorption and can fully absorb and store the polishing liquid. Its toughness, tensile strength, fatigue resistance are not in the same order of magnitude as those of pig hair and horse hair. The alternate distribution of the polyurethane polishing leather and the polymer sponge layer by layer makes the polishing effect better.

[0023] Working principle: The brush disc body restricts the vertical movement of the polishing brush disc through the limiting groove, and further restricts the horizontal rotation of the polishing brush disc through the detachable groove, thereby restricting the position of the polishing brush disc in the polishing machine. The brush hairs uniformly contact the surface of the glass through the arrangement of the straight holes in the brush disc body, and then polish the surface of the glass.

[0024] Embodiments of the present invention have been shown and described. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
