Description

Technical Field

[0001] This utility model relates to the field of optical glass technology, and in particular to an optical glass cleaning and polishing head. Background Technology

[0002] Optical glass cleaning and polishing heads are tools or equipment used to clean and polish optical components (such as lenses, mirrors, etc.). In the optical manufacturing process, it is very important to ensure the cleanliness and precise polishing of optical surfaces, because any tiny imperfections may affect the performance of optical components.

[0003] The following methods or tools are generally used when cleaning optical glass:

[0004] Cleaning solution: Specialized optical glass cleaning solution, which usually contains mild chemical cleaners to remove grease, dust and other contaminants;

[0005] Ultrasonic cleaning machine: It cleans optical components by using the vibrations generated by ultrasonic waves, and can very effectively remove tiny dirt and particles;

[0006] High-pressure gas jetting: Using dry compressed gas to jet optical surfaces to remove stubborn dust and particles;

[0007] Polishing powder: Fine polishing particles used to finely grind and level optical surfaces during the polishing process;

[0008] Polishing cloth / wheel: Used in conjunction with polishing powder, it can be made of cloth or other materials, and is designed to provide a soft surface with a certain degree of friction for polishing operations;

[0009] Cleaning paper or lint-free cloth: Used to gently wipe optical surfaces, reducing the risk of scratches and damage;

[0010] Mirror polishing machine: A device specifically designed for polishing mirrors. It can maintain constant pressure and speed to achieve high-precision polishing results.

[0011] Currently, most polishing heads used for cleaning optical glass have a relatively simple overall shape, and the cleaning methods for different parts of the optical glass are also limited. In particular, they cannot effectively clean the edges, large areas, and specific points of the optical glass. As a result, if the optical glass surface is large, the cleaning time will be greatly increased, and the single polishing head will also affect the cleaning quality. Utility Model Content

[0012] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by providing an optical glass cleaning and polishing head.

[0013] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] Design an optical glass cleaning and polishing head, including a central column, an integrally formed edge polishing layer at the middle position of the central column, an integrally formed large-area polishing layer at the lower end of the central column, an integrally formed local spot polishing layer on the outer ring wall of the large-area polishing layer, a polishing drive bushing fitted to the upper end of the central column, a threaded sleeve through the outer ring wall of the polishing drive bushing, the connection between the threaded sleeve and the polishing drive bushing being fixed by welding, a threaded knob through the inside of the threaded sleeve, the threaded knob including a threaded rod and a torsion knob, the outer threaded surface of the threaded rod being threadedly connected to the inner threaded surface of the threaded sleeve, and the outer end of the threaded rod being welded to the surface of the torsion knob.

[0015] In detail, the central pillar, the edge polishing layer, the large area polishing layer, and the local spot polishing layer are all made of jade or polyurethane material.

[0016] In detail, the edge polishing layer and the large area polishing layer are both disc structures, the local spot polishing layer is a ring structure, and the local spot polishing layer wraps around the edge of the large area polishing layer.

[0017] In detail, the edge polishing layer has a structure with convex ends and concave middle, and the concave part has an annular groove structure.

[0018] In detail, a threaded ring is provided through the bottom of the inner part of the polishing drive bushing, and the connection between the threaded ring and the polishing drive bushing is fixed by welding.

[0019] In detail, the internal threaded connection of the threaded ring is with a bolt, and the bolt has a hexagonal end structure.

[0020] In detail, the end of the central column is provided with a threaded groove, and the other end of the bolt is threadedly connected to the threaded groove.

[0021] The design scheme proposed in this utility model has the following beneficial effects in application:

[0022] 1. By setting multiple polishing layers on the central column, the corresponding polishing of large areas, local points, and edge positions of optical glass can be achieved. Compared with polishing multiple positions of a single polishing structure, the polishing quality and polishing efficiency can be greatly improved.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figures 1-4 An optical glass cleaning and polishing head includes a central post 10, an integrally formed edge polishing layer 11 at the middle position of the central post 10, an integrally formed large area polishing layer 12 at the lower end of the central post 10, an integrally formed local spot polishing layer 13 on the outer ring wall of the large area polishing layer 12, a polishing drive bushing 14 attached to the upper end of the central post 11, a threaded sleeve 15 penetrating the outer ring wall of the polishing drive bushing 14, the connection between the threaded sleeve 15 and the polishing drive bushing 14 being fixed by welding, a threaded knob 16 penetrating the inside of the threaded sleeve 15, and the threaded knob 16 including a threaded rod and a torsion knob, the outer threaded surface of the threaded rod being threadedly connected to the inner threaded surface of the threaded sleeve 15, and the outer end of the threaded rod being welded to the surface of the torsion knob.

[0031] It should be further noted that the central pillar 10, the edge polishing layer 11, the large area polishing layer 12, and the local spot polishing layer 13 are all made of jadeite or polyurethane. Jadeite is a hard and brittle silicate mineral. Due to its moderate hardness and brittleness, as well as its excellent polishing effect, jadeite is often used for fine polishing of the surfaces of optical glass, crystals, gemstones, and other hard materials. Polyurethane is a synthetic rubber material with good wear resistance and elasticity, and is suitable for polishing various surfaces.

[0032] It should be further explained that both the edge polishing layer 11 and the large area polishing layer 12 are disc structures, while the local point polishing layer 13 is a ring structure. The local point polishing layer 13 wraps around the edge of the large area polishing layer 12, which can be used for corresponding polishing of large areas, local points, and edge positions of optical glass. Compared with polishing multiple positions of a single polishing structure, this can greatly improve polishing quality and increase polishing efficiency.

[0033] It should be further explained that the edge polishing layer 11 has a structure with convex ends and concave middle. The concave part has an annular groove structure, which can bring the edge of the optical glass into contact with the concave middle position and limit it through the convex parts at both ends. It can have a limiting rolling polishing effect during polishing.

[0034] It should be further noted that a threaded ring 20 is provided through the bottom of the polishing drive bushing 14. The connection between the threaded ring 20 and the polishing drive bushing 14 is fixed by welding. The polishing drive bushing 14 can be connected to the rotating shaft of the polishing machine to ensure the stable operation of the polishing head.

[0035] It should be further noted that the internal threaded connection of the threaded ring 20 is with bolt 21, which has a hexagonal end structure and can be quickly assembled using a bolt gun.

[0036] It should be further noted that the end of the center column 10 is provided with a threaded groove 22, and the other end of the bolt 21 is threadedly connected to the threaded groove 22, which can realize the stable installation of the polishing drive bushing 14 and the center column 10.

[0037] Working method: When it is necessary to install the polishing head and the rotating shaft of the polishing machine, the polishing drive bushing 14 is connected to the end of the center column 10. The bolts 21 are moved threadedly with the threaded ring 20, so that the bolts 21 can be threadedly connected with the threaded groove 22 to tighten them, thereby realizing the installation of the polishing drive bushing 14 and the center column 10. Then, the rotating shaft of the polishing machine is inserted into the polishing drive bushing 14. The rotating shaft of the polishing machine has a pre-cut threaded groove. Then, the threaded knob 15 is threadedly connected with the groove on the rotating shaft to achieve stable transmission and installation of the polishing head and the polishing machine.

[0038] By setting multiple polishing layers on the central column 10, corresponding polishing can be carried out on large areas, local points, and edge positions of optical glass. Compared with polishing multiple positions of a single polishing structure, this can greatly improve polishing quality and increase polishing efficiency.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
