[0028] On the basis of the first embodiment, the polishing mechanism further comprises a polishing unit, the polishing unit comprising a support 3, a polishing structure 4, a placing groove 204, a screw nut 205, a first motor 206 and a threaded rod 207. The placing groove 204 is arranged on the upper surface of the machine box 2 at the rear, the threaded rod 207 is arranged inside the placing groove 204, the output end of the first motor 206 is connected to the threaded rod 207 through a shaft coupling, and the screw nut 205 is threadedly connected to the threaded rod 207, cooperating with the threaded rod 207 to realize accurate adjustment of the polishing structure 4 in the horizontal direction. The support 3 is fixedly connected to the upper surface of the screw nut 205 at the bottom, supporting the polishing structure 4 and ensuring that it can stably polish. The polishing structure 4 is arranged below the support 3, polishes the outer circle of the optical crystal, and improves the surface quality of the crystal.

[0029] The upper surface of the support 3 is fixedly connected with a polishing liquid tank 5 for storing the polishing liquid to provide necessary lubrication and cooling for the polishing process. The upper surface of the polishing liquid tank 5 is provided with a liquid inlet for adding the polishing liquid to ensure continuous supply of the polishing liquid. The polishing liquid tank 5 is internally provided with a water pump 502, and the outlet of the water pump 502 is connected with a water pipe 501 for pumping the polishing liquid out of the polishing liquid tank 5 and uniformly spraying the polishing liquid onto the surface of the optical crystal on the conveying roller 603. The bottom of the water pipe 501 is directed towards the conveying roller 603 to transport the polishing liquid from the water pump 502 to the conveying roller 603 to ensure uniform spraying of the polishing liquid. The upper surface of the cabinet 2 is provided with a through groove 202 corresponding to the conveying roller 603 to allow the waste and polishing liquid generated during the polishing process to fall into the collecting tank 203.
