Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to a lens processing and polishing device which can prevent polishing powder from escaping. Background Art

[0002] Lenses are transparent materials made of optical materials such as glass or resin. They have one or more curved surfaces. Lenses can be used for a variety of purposes, such as vision correction, photography and observation, and decorative box display. The technical content and quality of lenses are usually reflected in three aspects: materials, optical design, and lens layers. In terms of materials, the development of lenses has gone through stages such as natural crystal lenses, optical glass lenses, and optical resin lenses. In the process of lens processing, polishing and grinding are often required. There are many types of lens processing and polishing devices currently available on the market, but there are still some disadvantages.

[0003] For example, in actual use, a general lens processing and polishing device directly uses a frosted sheet to polish and grind the lens. Generally, the lens is not clamped and fixed during the processing, which will cause the lens to shift during the polishing and grinding process, resulting in the lens not being polished finely. At the same time, a large amount of polishing powder will be generated during the lens grinding process. The polishing powder will escape and be inhaled by the operators, which will affect the health of the operators. In addition, the frosted sheet will generate a large amount of heat during the polishing process. If it is not cooled, the service life of the frosted sheet will be greatly shortened. Therefore, we propose a lens processing and polishing device that avoids the escape of polishing powder, so as to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4The utility model provides a technical solution: a lens processing and polishing device for preventing polishing powder from escaping, comprising: an operating table 1, a support frame 2, an electric telescopic rod 3, a fixed rod 4, a moving rod 5, a fixed pin 6, a connecting frame 7, a rubber pad 8, a clamping plate 9, a lens body 10, a concentration cover 11, a pipeline 12, a concentration box 13, an activated carbon box 14, an exhaust fan 15, a frosting sheet 16, a hydraulic rod 17, a motor 18, an electric fan 19, a protective filter 20 and a waste box 21;

At the same time, a connecting frame 7 is rotatably installed on the inner side of the fixed rod 4, a fixing pin 6 is arranged above the connecting frame 7, and the fixing pin 6 is tightly connected to the inside of the moving rod 5. In addition, a clamping plate 9 is installed on the inner and outer sides of the connecting frame 7, a rubber pad 8 is installed on the inner side of the clamping plate 9, and the rubber pad 8 is arranged on the outer side of the lens body 10, that is, the electric telescopic rod 3 is opened, and the electric telescopic rod 3 is opened. The output end will push the moving rod 5 to move inside the fixed rod 4. When the moving rod 5 moves inward inside the fixed rod 4, the moving rod 5 will make the connected fixing pin 6 drive the connecting frame 7 to move inward, so that the clamping plate 9 connected to the connecting frame 7 drives the rubber pad 8 to firmly clamp and fix the lens body 10. That is, the clamping plate 9 fixes the lens body 10, so that the position of the lens body 10 will not be shifted during the polishing process, and the polishing accuracy is guaranteed. The rubber pad 8 can reduce the clamping force of the clamping plate 9 on the lens body 10, and avoid damage to the lens body 10.

[0028] like Figure 1 and Figure 3As shown in the figure, after the lens body 10 is firmly clamped and fixed, a frosting sheet 16 is arranged above the lens body 10, and the frosting sheet 16 is installed on the output end of the hydraulic rod 17. The top of the hydraulic rod 17 is connected to the motor 18, that is, the hydraulic rod 17 is turned on, so that the output end of the hydraulic rod 17 pushes the frosting sheet 16 to move to the surface of the lens body 10, and then the motor 18 is turned on. The motor 18 can make the hydraulic rod 17 and the frosting sheet 16 rotate, that is, the frosting sheet 16 can polish and grind the lens body 10. In addition, a focusing cover 11 is also arranged on the outside of the hydraulic rod 17, and the focusing cover 11 is located above the lens body 10. The left side of the focusing cover 11 is connected to the pipeline 12, and the top of the pipeline 12 is connected to the focusing box 13.
