[0002] Optical lenses are generally optical components made of optical glass and transparent resin, and are widely used in the fields of lenses for optical instruments. Generally, an optical lens has at least one curved surface, which is used to refract light to achieve its purpose. During the processing of optical lenses, their surfaces need to be polished to make them smooth and reduce the reflection of light. However, dust will be generated during the polishing process, which is easy to pollute the environment. If the lens moves during the polishing process, the center point will be offset, which cannot meet the use requirements. Utility Model Content

[0024] like Figure 1-3 As shown, the device for centering an optical lens of the utility model comprises a processing platform 1, a supporting bowl 3 is provided on the processing platform 1, a rubber ring 31 is also provided on the upper edge of the supporting bowl 3, a supporting tube 2 is connected to the bottom of the supporting bowl 3, a first channel 11 connected to the supporting tube 2 is provided on the processing platform 1, a first pipe 9 located below the processing platform 1 is connected to the bottom of the first channel 11, and the first pipe 9 is externally connected to a negative pressure air pump; a rubber bowl 4 is also installed on the inner surface of the supporting bowl 3 through a connecting strip 32, the top end face of the rubber bowl 4 is located above the horizontal plane where the top end face of the rubber ring 31 is located, and the connecting strip 32 is made of rubber. When installing the lens on the rubber bowl 4, the rubber bowl 4 and the connecting strip 32 can be pressed to deform. At the same time, the connecting strip 32 can support the rubber bowl 4. The air inside the rubber bowl 4 is discharged, and a negative pressure is generated inside. The negative pressure can reach -0.1Mpa, and the lens can be adsorbed on the rubber bowl 4; the connecting strip 32 forms a channel between the rubber bowl 4 and the supporting bowl 3. When the negative pressure air pump is working, the negative pressure between the rubber bowl 4 and the supporting bowl 3 can cause the lens to be attracted to the supporting bowl 3.

[0025] A dust cover 5 is also provided on the processing platform 1 around the support bowl 3. The dust cover 5 is a bowl-shaped structure inverted on the processing platform 1. The top of the dust cover 5 is open, and the cross-section of the opening is larger than the cross-section of the top of the support bowl 3. The support bowl 3 and the rubber bowl 4 are located inside the dust cover 5.

[0026] like Figure 3 As shown, the dust cover 5 includes an outer shell 51 and an inner shell 52 disposed inside the outer shell 51. The inner shell 52 and the outer shell 51 are sealed at the bottom, and the upper inner shell 52 and the outer shell 51 are not in contact, so that an airflow channel is formed between the inner shell 52 and the outer shell 51. The height of the inner shell 52 is less than the height of the outer shell 51, and two connecting pipes 6 connected to the airflow channel are also provided on the inner surface of the inner shell 52. The processing platform 1 also has a second channel 12 that cooperates with the connecting pipe 6, and the second channel 12 is externally connected to a vacuum cleaner. A sealed cavity 8 is also fixedly installed on the lower surface of the processing platform 1. The second channel 12 is located in the sealed cavity 8. The first pipe 9 passes through the sealed cavity 8. The sealed cavity 8 is provided with a second pipe 10 connected to the vacuum cleaner. When the vacuum cleaner is working, the top of the dust cover 5 can inhale air, so that the top of the dust cover 5 forms an airflow sealing effect. When the grinding device goes deep into the dust cover 5 to process the lens, the dust generated will not leak out, avoiding dust pollution.

[0027] In addition, the processing platform 1 is also provided with a magnetic ring 7 that cooperates with the bottom of the dust cover 5. A rubber layer 71 is provided on the surface of the magnetic ring 7. When the dust cover 5 is placed on the processing platform 1, the rubber layer 71 can seal the space between the magnetic ring 7 and the dust cover 5 to prevent dust leakage from the surroundings.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
