[0002] Optical glass is now widely used in aerospace, military equipment, nuclear power, medical, and electronic equipment. The main types of optical glass components are optical positioning lenses and optical path adjustment lenses. Different applications have different quality requirements for the surface of optical glass.

[0003] Chinese patent CN221560778U discloses a curved optical glass polishing machine. This utility model can clamp the glass by setting a clamping mechanism, and can adjust the height of the polishing mechanism by setting a lifting mechanism. The polishing mechanism can polish the glass under the drive of the lifting mechanism. The convex polishing head fits with the concave surface of the glass, and the concave polishing head fits with the convex surface of the glass. The convex polishing head can be disassembled by pulling the pull block, and the concave polishing head can be replaced for easy polishing of both sides of the glass. The moving mechanism facilitates the movement of the device.

[0004] Chinese patent CN112536649A discloses an optical glass polishing method and apparatus based on magnetic abrasive flow. It employs a magnetic field generator to apply a magnetic field to the polishing slurry, adjusting the aggregation degree of abrasive particles in the slurry and increasing the friction between the part and the abrasive particles. This achieves micro-removal of material from the part by the abrasive particles, resulting in highly efficient polishing. This invention enables high-efficiency, low-damage polishing of curved optical glass parts at low cost.

[0005] In existing polishing equipment, the supply of polishing fluid is often not uniform and precise enough during the polishing process, which affects the polishing effect. Utility Model Content

[0006] The technical problem to be solved by this utility model is that, in the existing polishing devices, the supply of polishing fluid is often not uniform and precise enough during the polishing process, which affects the polishing effect.

[0007] To address the aforementioned problems, this utility model provides a polishing device for processing curved optical glass, comprising a base, a servo motor fixedly connected to the top of the base, a connecting shaft connected to the output end of the servo motor, an electric push rod connected to the bottom end of the connecting shaft, a polishing head connected to the telescopic end of the electric push rod via a telescopic rod, a compression spring sleeved on the telescopic rod, a polishing table fixedly connected to the base directly below the polishing head, a groove formed in the polishing table, a drain outlet at the bottom of the groove, a protective cover sleeved on the fixed end of the electric push rod, an annular water storage pipe fixedly connected to the inner wall of the protective cover via a snap fastener, multiple inclined nozzles equidistantly formed on the inner wall of the water storage pipe, a water inlet formed at the top of the water storage pipe, a water pipe threaded into the water inlet, and the water pipe passing through the protective cover away from the water storage pipe and connected to a water tank containing polishing liquid via a suction pump, a dustproof net fixedly connected to the inner wall of the protective cover and sleeved on the surface of the fixed end of the electric push rod, the dustproof net being located below the water storage pipe.

[0008] In summary, the overall solution and effect of the aforementioned polishing device can be described in one sentence.

[0009] As a further supplement to this application, an inclined filter screen is fixedly connected to the inner wall of the groove, and the filter screen is located below the placement platform. A drain port corresponding to the filter screen is opened on the side of the base, and a collection box located below the drain port is placed on the side of the base.

[0010] As a further supplement to this application, the clamping assembly includes a support frame symmetrically fixed to the side wall of the placement platform, and an electric guide rail is fixedly connected to the top of the support frame.

[0011] As a further supplement to this application, the electric guide rail is symmetrically connected to the slide rod via a slider, and the two electric guide rails are each fitted with a clamp by screws at one end close to each other.

[0012] As a further supplement to this application, a screw hole is provided at the top of the clamping plate, and a threaded rod is connected to the screw hole by a thread, with an anti-slip pad movably connected to the bottom end of the threaded rod.

[0013] As a further supplement to this application, a movable ball is fixedly connected to the bottom end of the threaded rod via a coupling, and a slot is fixedly connected to the anti-slip pad near one end of the threaded rod, and the slot engages with the movable ball.

[0014] As a further supplement to this application, a controller for controlling the suction pump, electric guide rail, servo motor and electric push rod is fixedly connected to the base.

[0015] In summary, after the curved optical glass is placed on the placement table and positioned by the clamping assembly, the controller activates the electric push rod to move the protective cover down to contact the top of the polishing table. At this point, the polishing head forms a stable contact with the curved optical glass under pressure. Subsequently, the controller activates the servo motor to drive the connecting shaft and the electric push rod to rotate, thereby enabling the polishing head to polish the curved optical glass. During the polishing process, the compression spring automatically adjusts the contact pressure of the polishing head through elastic deformation. At the same time, the controller activates the suction pump to deliver polishing liquid to the water storage pipe through the water pipe. The polishing liquid is sprayed all around the surface of the curved optical glass through the nozzle, and the polishing liquid is shielded by the protective cover to effectively prevent the polishing liquid from splashing outside the polishing table, facilitating cleaning and maintenance. The dust generated during the polishing process is shielded by the dustproof net to prevent dust from entering the nozzle and causing blockage. The polishing liquid on the surface of the curved optical glass flows into the groove and is discharged from the drain. Attached Figure Description

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-2 A polishing device for processing curved optical glass is shown, including a base 1. A servo motor 2 is fixedly connected to the top of the base 1. A connecting shaft 3 is connected to the output end of the servo motor 2. An electric push rod 7 is connected to the bottom end of the connecting shaft 3. A polishing head 8 is connected to the telescopic end of the electric push rod 7 through a telescopic rod. A compression spring 14 is sleeved on the telescopic rod. A polishing table 9 is fixedly connected to the base 1 directly below the polishing head 8. A groove is opened in the polishing table 9 in the base 1. A drain outlet 11 is opened at the bottom of the groove. A protective cover 4 is sleeved on the fixed end of the electric push rod 7. An annular water storage pipe 5 is fixedly connected to the inner wall of the protective cover 4 through a buckle. Multiple inclined nozzles 13 are opened at equal intervals on the inner wall of the water storage pipe 5. A water inlet is opened at the top of the water storage pipe 5. A water pipe is threaded into the water inlet. The water pipe passes through the protective cover 4 away from the water storage pipe 5 and is connected to a water tank containing polishing liquid through a suction pump. A dustproof net 6 is fixedly connected to the inner wall of the protective cover 4 and is sleeved on the surface of the fixed end of the electric push rod 7. The dustproof net 6 is located below the water storage pipe 5.

[0027] A controller is fixedly connected to the base 1 to control the suction pump, electric guide rail 17, servo motor 2 and electric push rod 7.

[0028] The electric actuator 7 adopts existing technology, and those skilled in the art shall select a suitable electric actuator 7 from the existing technology for installation, such as SMC MXQ10-20A.

[0029] Working principle: After the curved optical glass is placed on the placement table 15 and positioned by the clamping assembly, the controller activates the electric push rod 7 to move the protective cover 4 down to contact the top of the polishing table 9. At this time, the polishing head 8 forms a stable contact with the curved optical glass under pressure. Then, the controller activates the servo motor 2 to drive the connecting shaft 3 and the electric push rod 7 to rotate, thereby making the polishing head 8 polish the curved optical glass. During the polishing process, the compression spring 14 automatically adjusts the contact pressure of the polishing head 8 through elastic deformation. At the same time, the controller activates the suction pump to deliver polishing liquid to the water storage pipe 5 through the water pipe. The polishing liquid is sprayed all around the surface of the curved optical glass through the nozzle 13. The polishing liquid is blocked by the protective cover 4 to effectively prevent the polishing liquid from splashing outside the polishing table 9, which is convenient for cleaning and maintenance. The dust generated during the polishing process is blocked by the dustproof net 6 to prevent dust from entering the nozzle 13 and causing blockage. The polishing liquid on the surface of the curved optical glass flows into the groove and is discharged from the drain outlet 11.

[0030] In this invention, a protective cover 4 is placed over the surface of curved optical glass. During the polishing process, polishing liquid is sprayed onto the surface of curved optical glass through multiple nozzles 13 on the annular water storage pipe 5 to achieve uniform spraying.

[0031] Second implementation method:

[0032] Figures 3-6 An inclined filter screen 19 is fixedly connected to the inner wall of the groove, and the filter screen 19 is located below the placement platform 15. A drain port 10 corresponding to the filter screen 19 is opened on the side of the base 1. A receiving box 12 located below the drain port 10 is placed on the side of the base 1. The clamping assembly includes a support frame 16 symmetrically fixed to the side wall of the placement platform 15. An electric guide rail 17 is fixedly connected to the top of the support frame 16. A slide rod 18 is symmetrically connected to the electric guide rail 17 through a slider. A clamping plate 20 is installed at one end of each of the two electric guide rails 17 close to each other by screws. A screw hole is opened at the top of the clamping plate 20. A threaded rod 21 is threadedly connected to the screw hole. An anti-slip pad 22 is movably connected to the bottom end of the threaded rod 21. A movable ball 23 is fixedly connected to the bottom end of the threaded rod 21 through a coupling. A slot 24 is fixedly connected to the end of the anti-slip pad 22 close to the threaded rod 21, and the slot 24 engages with the movable ball 23.

[0033] Working principle: The curved optical glass is placed between two clamping plates 20. Then, the controller turns on the electric guide rail 17 to drive the two sliding rods 18 to move closer to each other, thereby clamping the curved optical glass. Then, the threaded rod 21 is turned to move the anti-slip pad 22 to contact the surface of the curved optical glass. The anti-slip pad 22 is movably connected to the threaded rod 21 through the movable ball 23, so that when the anti-slip pad 22 contacts the curved optical glass, the angle can be adjusted according to the curvature of the surface, thereby better fixing the curved optical glass on the two clamping plates 20 for polishing. During the polishing process, the polishing liquid on the surface of the curved optical glass flows into the filter screen 19 in the groove to filter the dust. The filtered polishing liquid can be recycled after purification. The filter screen 19 is inclined. After the filtered dust accumulates, it can be discharged from the drain port 10 to the collection box 12.

[0034] This invention, by setting an adjustable clamp, can clamp and position curved optical glass of different sizes and models.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
