[0035] like Figures 1 to 7 As shown, the utility model provides a lens grinding and polishing device, including a mounting frame 1, a metal grid 2 is fixedly connected to the top end of the interior of the mounting frame 1, and a centrifugal fan 28 fixedly connected to the interior of the mounting frame 1 is provided below the metal grid 2, the top end of the mounting frame 1 is fixedly connected to a mounting cavity 4, and the interior of the mounting cavity 4 is fixedly connected to a guide fan 29, both ends of the mounting cavity 4 are fixedly connected to a metal dustproof net, and the interior of the mounting cavity 4 is fixedly connected to a device for blowing off the polishing block 6 and impurities attached to the surface of the lens sheet.

[0036] The guide fan 29 installed inside the mounting cavity 4 is used to blow off impurities attached to the polishing block 6 and the lens surface during the processing. At the same time, the impurities generated by the processing are sucked into the interior of the mounting frame 1 by the provided centrifugal fan 28 and transmitted to the storage cavity 21.

[0037] like Figure 1 and Figure 2 As shown, one end of the connecting frame 3 is fixedly connected to the connecting plate 11, and the outer side wall of the connecting plate 11 is vertically movably connected to the sliding sleeve 10, one end of the sliding sleeve 10 is fixedly connected to the mounting plate 9, and the top of the mounting plate 9 is fixedly connected to the first motor 8, the output end of the first motor 8 passes through the top of the mounting plate 9, and is fixedly connected to the top of the mounting disk 5, one side of the bottom end of the mounting disk 5 is fixedly connected to a polishing block 6 for grinding and polishing the lens, and the other side of the bottom end of the mounting disk 5 is fixedly connected to a cleaning brush 7, and the size and shape of the polishing block 6 are adapted to the top surface of the lens to be ground and polished.

[0038] By vertically moving the sliding sleeve 10 on the outer side wall of the connecting plate 11, the polishing block 6 and the cleaning brush 7 are driven to adapt to the top end of the lens to be polished and ground, so that the inner wall of the bottom end of the polishing block 6 fits the top surface of the lens. Then, the first motor 8 is powered on for output to drive the mounting disc 5 to rotate, so as to polish the top end of the lens through the polishing block 6. At the same time, the impurities adhered to the top end of the lens are removed through the arranged cleaning brush 7, effectively avoiding the impurities generated by the bonding, polishing and grinding at the top end of the lens.

[0039] As Figure 1 and Figure 2 shown, further, one end of the sliding sleeve 10 far from the mounting plate 9 is fixedly connected with a connecting lead screw sleeve 15, and the inner side wall of the connecting lead screw sleeve 15 is meshed with a transmission lead screw 13. The transmission lead screw 13 is movably connected between two mounting pieces 12. Both of the two mounting pieces 12 are fixedly connected to one side of the connecting plate 11. The top end of the top mounting piece 12 is fixedly connected with a second motor 14, and the output end of the second motor 14 is in transmission connection with the top end of the transmission lead screw 13.

[0040] The second motor 14 drives the transmission lead screw 13 to rotate horizontally. Then, through the lead screw transmission structure formed by the transmission lead screw 13 and the connecting lead screw sleeve 15, the connecting lead screw sleeve 15 moves up and down, and then drives the sliding sleeve 10 to move up and down. Thus, the sliding sleeve 10 drives the mounting plate 9 to move, so that the polishing block 6 and the cleaning brush 7 adapt to the top end of the lens to be polished and ground.

[0041] As Figure 1 and Figure 2 shown, the top end of the mounting frame 1 is symmetrically and fixedly connected with side plates 16. One end of the side plate 16 is fixedly connected with a cylinder 17. The output end of the cylinder 17 penetrates through one end of the side plate 16 and is fixedly connected with one end of a transmission plate 18 arranged in an "L" shape. The other end of the transmission plate 18 is fixedly connected with a contact balloon 20 through a connecting plate 19.

[0042] The cylinder 17 is driven to move the transmission plate 18 towards the connecting frame 3. In this way, until the contact balloon 20 abuts against the outer side wall of the lens to be polished and ground, different-sized lenses can be limited and fixed, and the outer wall of the lens can be adapted, compared with the problem that the fixing effect of the outer wall of the special-shaped lens by the traditional limiting device is poor.

[0043] As Figure 1 、 Figure 4 and Figure 5As shown, the bottom end of the mounting frame 1 is communicated with the top end of the storage cavity 21, and the bottom end of the mounting frame 1 is fixedly connected to the top end of the storage cavity 21, and the inner side wall of the storage cavity 21 is symmetrically provided with a guide rail 22 with a "convex" structure as the inner side wall, and the internal movably connected to the guide slide rail 22 is a guide slider 23 with a "convex" structure, the guide slider 23 is symmetrically fixedly connected to the outer walls on both sides of the storage box 24, and is fixedly connected to the inner bottom end of the storage box 24 with a male Velcro 25 with a velvet structure, the top end of the male Velcro 25 is adhesively fixedly connected to a female Velcro 26 with a hook structure, and the female Velcro 26 is fixedly connected to the bottom end of the adhesive layer 27.

[0044] Impurities generated during lens grinding and polishing are stored in the storage box 24, and the centrifugal force generated by the centrifugal fan 28 adsorbs the impurities and then adheres them to the top of the adhesive layer 27. At the same time, after daily processing is completed, the storage box 24 is separated from the storage cavity 21 by the guide slider 23, and the adhesive layer 27 is separated, cleaned or replaced. Since the adhesive layer 27 is fixed by the male Velcro 25 and the female Velcro 26, the convenience of the adhesive layer 27 is improved through the quick-release design, thereby realizing the processing of impurities during the lens grinding and polishing process, and avoiding the scattering of impurities to affect the operator and the lens.

[0045] Principle and process of this utility model:

[0046] First, the lens to be polished is placed on the top of the connecting frame 3, and then the cylinder 17 drives the transmission plate 18 to move toward the outer wall of the lens to be fixed, until the interference balloon 20 contacts the outer wall of the lens to be polished and fixes it;

[0047] Secondly, the output shaft of the second motor 14 drives the transmission screw 13. In this way, the screw transmission structure formed by the transmission screw 13 and the connecting screw sleeve 15 drives the sliding sleeve 10 to move up and down, so that the sliding sleeve 10 moves and drives the mounting plate 9, thereby making the polishing block 6 and the cleaning brush 7 fit the top of the lens to be polished;

[0048] Then, the mounting plate 5 is driven to rotate by the first motor 8, and the mounting plate 5 rotates the polishing block 6 and the cleaning brush 7, so that the polishing block 6 polishes the top of the lens. At the same time, the cleaning brush 7 removes impurities adhered to the top of the lens. In addition, the guide fan 29 installed inside the mounting cavity 4 blows off impurities attached to the polishing block 6 and the surface of the lens during the processing. At the same time, the centrifugal fan 28 sucks impurities generated during the processing into the interior of the mounting frame 1 and transfers them to the storage cavity 21.

[0049] Finally, through the centrifugal force generated by the centrifugal fan 28, impurities are adsorbed and then adhered to the top of the adhesive layer 27. At the same time, after the daily processing is completed, the storage box 24 is movably separated from the storage cavity 21 through the guiding slider 23, and the adhesive layer 27 is separated, cleaned or replaced. In this way, a lens grinding and polishing device is completed for use;
