[0002] Optical lenses are transparent materials with one or more curved surfaces, made of optical materials such as glass or resin. After polishing, they are often assembled with eyeglass frames to make eyeglasses, used to correct the user's vision and obtain a clear field of vision. There are many ways to classify lenses, such as according to the material, function and surface treatment process. Optical lens polishing is required during the processing of optical lenses.

Support legs are fixedly connected to the four corners of the bottom of the worktable, and electric telescopic rods are fixedly connected to both sides of the top of the worktable. A fixing plate is fixedly connected to the top of the electric telescopic rod, and a motor is fixedly connected to the side of the fixing plate away from the electric telescopic rod. A buffer mechanism is fixedly connected to the bottom of the motor shaft.

[0004] In the aforementioned prior art, although the optical lens can be fixed by the cooperation of the electric telescopic rod, the fixed plate, the motor, the buffer mechanism, the connecting plate, the polishing disc, the support platform, the annular groove, the first spring and the movable tube, and the dust generated during polishing can be collected by the cooperation of the two dust hoods, the air pump and the dust collection box, it is impossible to fix optical lenses of different diameters. At the same time, the dust removal effect is poor when only two dust hoods are used to remove dust. Therefore, an optical lens polishing device is proposed now. Utility Model Content

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 An optical lens polishing device includes a base 1 and a base plate 2. A worktable 3 is fixedly connected to the top of the base plate 2. An annular dust suction pipe 4 is fixedly connected to the surface of the worktable 3. Movable and uniformly distributed arc-shaped clamps 5 are provided on the surface of the worktable 3. A polishing machine 6 is provided above the worktable 3.

[0023] It should be noted that the specific models and specifications of the servo motor 11, polishing machine 6, electric push rod 20, and air extractor 18 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described. All of them can be powered by external devices and controlled to turn on and off.

[0024] Furthermore, the worktable 3 has a cavity 7 inside, and the top of the cavity 7 has a circular groove 8 and a circumferentially distributed sliding groove 9. The surface of the worktable 3 has rectangular openings 10 that are uniformly distributed and communicate with the inside of the sliding groove 9. A servo motor 11 is fixedly connected to the bottom of the cavity 7. The output end of the servo motor 11 is provided with a rotating shaft. The top of the rotating shaft is fixedly connected to a first bevel gear 12. The first bevel gear 12 is meshed with a second bevel gear 13 that is circumferentially distributed. The second bevel gear 13 is fixedly connected to a screw 14. The screw 14 is rotatably connected to the worktable 3. It should be noted that the servo motor 11 controls the rotation of multiple screws 14 through the first bevel gear 12 and multiple bevel gears. The multiple screws 14 control multiple arc-shaped clamps 5 to move closer to each other through multiple sliders 15 and multiple rectangular blocks, and clamp and fix the optical lens 21 through silicone pads.

[0025] It should be noted that the screw 14 is located inside the slide groove 9, and not directly below the rectangular opening 10. The screw 14 can rotate normally inside the slide groove 9 and control the movement of the slider 15.

[0026] The screw 14 is threadedly connected to a slider 15, which is slidably connected to the slide groove 9. A rectangular block is fixedly connected to the top of the slider 15, which is slidably connected to the rectangular opening 10. The top of the rectangular block is fixedly connected to the arc-shaped clamping plate 5. It should be noted that by limiting the sliding of the slider 15 and the slide groove 9, as well as limiting the sliding of the rectangular block and the rectangular opening 10, multiple arc-shaped clamping plates 5 can perform stable horizontal linear motion.

[0027] A silicone pad is installed on one side of the arc-shaped clamp 5. It should be noted that the silicone pad is elastic and can provide good protection for the outer wall of the optical lens 21.

[0028] Furthermore, an annular suction port 16 is provided at the top of the inner wall of the annular suction pipe 4. It should be noted that the annular suction port 16 is located above the optical lens 21, and the air pump 18 will suck out the air inside the annular suction pipe 4 through the delivery pipe 17 and the suction pipe. The annular suction pipe 4 will generate negative pressure, which can generate suction at the annular suction port 16, and the annular suction port 16 can suck in the dust generated during polishing.

[0029] The outer wall of the annular suction pipe 4 is fixedly connected with conveying pipes 17 that are equidistantly distributed in a circle. The conveying pipes 17 are fixedly connected to the base plate 2. An air extractor 18 is installed on the top of the base 1. An air extraction hood is connected to the top of the air extractor 18 through an air extraction pipe. The air extraction hood is connected to the conveying pipe. A dust collection box 19 is connected to one side of the air extractor 18 through an exhaust pipe.

[0030] It should be noted that the polishing machine 6 and the dust collection box 19 are both existing technologies. The polishing machine 6 can polish the surface of the optical lens 21 and collect the dust discharged by the vacuum pump 18. The specific structure and principle are described in detail in the patent document proposed in the background art: an optical lens polishing device (publication number: CN211277769U), and will not be described again.

[0031] Furthermore, electric push rods 20 are symmetrically arranged on the top of the base plate 2. A support plate is fixedly connected to the top of the electric push rod 20. The support plate is fixedly connected to the polishing machine 6. The bottom of the electric push rod 20 is connected to the base plate 2 through a mounting plate and multiple mounting bolts. It should be noted that the electric push rod 20 can control the upward and downward movement of the polishing machine 6. The electric push rod 20 can be installed on the top of the base plate 2 and is also easy to remove from the base plate 2.

[0032] Furthermore, the bottom of the base plate 2 is fixedly connected with evenly distributed fixing rods, the bottom of which is fixedly connected to the base 1. It should be noted that the multiple fixing rods can provide support for the base plate 2.

[0033] Furthermore, an optical lens 21 is placed on the top of the workbench 3, and the top of the base 1 is provided with evenly distributed mounting holes. It should be noted that mounting bolts can be inserted into the mounting holes to fix the base 1 to other equipment and prevent the base 1 from shaking.

[0034] Working principle of this utility model:

[0035] First, the operator places the optical lens 21 on the surface of the workbench 3;

[0036] Then, the servo motor 11 is turned on. The servo motor 11 controls the rotation of multiple screws 14 through the first bevel gear 12 and multiple bevel gears. The multiple screws 14 control multiple arc-shaped clamps 5 to move closer to each other through multiple sliders 15 and multiple rectangular blocks, and clamp and fix the optical lens 21 through the silicone pad.

[0037] Finally, when the polishing machine 6 polishes the optical lens 21 and generates dust, the vacuum pump 18 will suck out the air inside the annular suction pipe 4 through the delivery pipe 17, the suction hood and the suction pipe, which can generate suction at the annular suction port 16. The annular suction port 16 can suck in the dust generated by polishing and discharge it into the dust collection box 19 through the delivery pipe 17, the suction pipe and the exhaust pipe.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
