Description

Technical Field

[0001] This invention relates to the field of glass polishing technology, and in particular to an automatic polishing device for glass circular holes. Background Technology

[0002] Polishing refers to the processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. It is a finishing process that uses polishing tools and abrasive particles or other polishing media to modify the surface of a workpiece, remove textures, scratches, and other defects from glass, improve the transparency and refractive index of glass, and make the glass more vitrified.

[0003] Existing glass hole polishing devices cannot accurately locate the center of the hole, resulting in eccentricity during polishing. This leads to uneven polishing results or mismatch between the polishing head and the hole, causing damage to the glass and requiring rework, which greatly affects the polishing efficiency. Furthermore, existing glass hole polishing devices cannot polish glass holes of different sizes, requiring continuous replacement of polishing components to achieve the desired size, which also significantly impacts polishing efficiency. Summary of the Invention

[0014] Compared with existing technologies, the advantages of this invention are: 1. The center positioning mechanism uses the center point of the cross-section of a universal ball wheel to pinpoint the center of the circular hole, enabling precise alignment with the actual dimensions of the glass hole. The universal ball wheel allows the positioning mechanism to roll freely upon contact with the glass surface, reducing frictional resistance and further ensuring accurate center positioning. This provides an accurate foundation for subsequent polishing operations and reduces uneven polishing results caused by misalignment of the positioning center.

[0015] 2. The polishing mechanism utilizes centrifugal force for polishing. During rotation, the polishing components expand outwards evenly under the action of centrifugal force and make close contact with the inner wall of the glass hole. The uniform contact force ensures that the polishing material is applied evenly to the surface of the glass hole, avoiding the problems of over- or under-polishing in certain areas that may occur in traditional polishing methods, thus ensuring uniform polishing quality of the inner wall of the glass hole.

[0016] 3. By adjusting the rotation speed of the polishing mechanism and the weight of the counterweights at both ends, the polishing of round holes in glass of different materials, sizes, and roughness requirements can be flexibly adapted. For glass with high hardness or high requirements for the surface of the round hole, the rotation speed range can be appropriately reduced, and a softer polishing material can be used to achieve fine polishing. For glass with low hardness or many surface defects in the round hole, the rotation speed range can be increased, and a harder polishing material can be used to quickly remove defects. When polishing circular conical holes, the weight of the upper and lower ends of the counterweights can be adjusted for polishing.

[0017] In summary, the circular positioning mechanism of this invention uses the center point of the cross-section of the universal ball wheel to locate the center of the circular hole, which can accurately fit according to the actual size of the glass circular hole, reducing the uneven polishing effect caused by the eccentricity of the positioning center. It uses centrifugal force for polishing, and the uniform contact force allows the polishing material to act evenly on the surface of the glass circular hole. By adjusting the rotation speed of the polishing mechanism and the weight of the counterweights at both ends, it can flexibly adapt to the polishing of glass circular holes of different materials, sizes and roughness requirements.
