Description

Technical Field

[0001] The present invention relates to the field of optical lens manufacturing, and in particular to a high-precision optical lens manufacturing device and a manufacturing method thereof. Background Art

[0002] Optical lenses are transparent components manufactured using optical principles. They are mainly used to focus, diverge or adjust the direction of light propagation. The production steps of optical lenses include batching, melting and molding. Finally, the produced optical lenses are polished and formed according to specific needs.

[0003] When polishing an optical lens, a motor drives the grinding wheel to rotate and polish the optical lens raw material so that the optical lens forms a required shape. During the specific polishing process, some lenses need to be polished on the sides so that the shape of the lens is suitable for the equipment. When the grinding wheel contacts the lens for polishing, the lens will vibrate and wear will occur between the lens and the fixture. Therefore, a rubber block needs to be set at the fixture head. Because the use of rubber blocks requires fine control of the clamping force of the fixture to avoid vibration of the lens resulting in reduced accuracy when the clamping force is too small, or breakage of the lens during processing when the clamping force is too large. To address the above problems, a patent application with patent publication number CN219666092U provides a glass lens polishing device for optical instrument manufacturing, which drives the movable seats on both sides to move toward the middle through a second motor, so that the clamping plate on the fixed plate clamps the glass lens. However, a certain amount of debris will be generated during the polishing process of the grinding wheel, and the generated debris will splash everywhere. If the debris accidentally splashes onto the lens, it will cause the lens to be scratched, seriously affecting the clarity of the optical lens.

[0004] To this end, a high-precision optical lens manufacturing device and a manufacturing method thereof are proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-precision optical lens manufacturing device and a manufacturing method thereof to solve the problem that the clamping force of the fixture needs to be finely controlled, and at the same time solve the problem that debris generated during the grinding process scratches the lens, seriously affecting the clarity of the optical lens.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A high-precision optical lens manufacturing device comprises a shell, a fixture is installed in the shell, a grinding wheel is provided on one side of the fixture, the grinding wheel is connected to a drive motor, the drive motor is fixedly installed inside the shell, a disc is fixedly installed on the chuck of the fixture, a circular window is opened at the bottom of the disc, a rubber extrusion block is provided in the circular window, a sealed chamber is formed between the disc and the rubber extrusion block, an air pump is installed in the shell, a pipe is connected between the air pump and the sealed chamber, an adjustment component is installed on the drive motor, the adjustment component is installed on the pipe and connected to the drive motor, the air pump inflates the sealed chamber through the pipe, and when the lens is roughly processed by the grinding wheel, the adjustment component controls the air pump to increase the amount of air entering the disc, and when the grinding wheel is fine-processing the lens, the adjustment component controls the air pump to reduce the amount of air entering the disc.

[0008] When producing lenses, it is necessary to prepare the raw materials first, batch the raw materials, and pour the batches into the furnace for melting. Finally, pour the molten glass into the mold and form the lens raw material after cooling. When optical lenses of different shapes and structures are required, grinding equipment is required. Before use, the lens raw material to be polished needs to be placed in the shell, and the clamps on both sides are pushed to operate so that the clamps on both sides push the two oppositely arranged discs closer to each other, and align the rubber extrusion blocks on the discs with the lens raw material to be polished. The middle lens raw material is clamped by the rubber extrusion blocks so that the middle lens raw material is fixed. After the fixation is completed, the air pump is used to inflate the sealed chamber so that the gas in the sealed chamber is continuously compressed, and the compressed gas will squeeze the rubber extrusion blocks. The squeezed rubber extrusion blocks will further press against the lens surface, fixing the lens while protecting the surface of the lens. At this time, the drive motor is started, and the drive motor drives the grinding wheel on the output shaft to rotate to grind the lens. It should be noted that when the grinding wheel is rough-processing the lens, because it is necessary to increase Increase the number of revolutions of the grinding wheel and the speed of movement of the grinding wheel. A high-speed rotating grinding wheel has high cutting efficiency, but is prone to vibration and scratches, which increases the surface roughness of the lens. Therefore, it is necessary to adjust the component to control the air pump to reduce the amount of air entering the disc cylinder, reduce the pressure in the sealed chamber, reduce the squeezing force of the rubber extrusion block on the lens, and prevent the lens from breaking due to excessive pressure. At the same time, because it is rough processing, the shaking of the lens will not affect the production of the optical lens too much. When finishing the lens, because it is necessary to reduce the number of revolutions of the grinding wheel and the speed of movement of the grinding wheel, and at the same time ensure the accuracy of the grinding, it is necessary to adjust the component to control the air pump to increase the amount of air entering the disc cylinder, increase the pressure in the sealed chamber, increase the squeezing force of the rubber extrusion block on the lens, so that the lens is firmly fixed and ensure that the lens does not shake during the grinding process. The rubber extrusion block protects the surface of the lens while ensuring the accuracy of the lens during the grinding process, ensuring that the debris splashed by the grinding wheel during grinding does not cause wear on the surface of the lens, and ensuring the clarity of the optical lens after processing.

[0009] Preferably, the adjustment assembly includes a deflection plate, a limit column, a counterweight, a first compression spring, a spur rack, a mounting plate, a threaded rod, and a gear. The deflection plate is fixedly mounted on the rotating shaft of the driving motor, and a plurality of evenly distributed long slots are opened on the deflection plate. The limit column is fixedly mounted in the long slot, and a counterweight is sleeved on the limit column. The counterweight slides in the long slot, and a first compression spring sleeved on the limit column is in contact with one side of the counterweight and the inner wall of the long slot. A spur rack is fixedly mounted on the counterweight, and a mounting plate is installed on the driving motor. A threaded rod is rotatably connected to the mounting plate, and a gear is fixedly mounted on the movable end of the threaded rod, and the gear is meshed with a plurality of spur gears. An air guide is provided on the mounting plate, and the air guide is connected to a pipeline, and the air guide discharges excess gas from the sealed chamber.

[0010] When in use, the output shaft of the driving motor drives the deflection disk fixed thereon to rotate. When the output shaft of the driving motor rotates at high speed, the rotation increases the centrifugal force, causing the counterweight on the deflection disk to slide toward the outer edge of the deflection disk and squeeze the first compression spring sleeved on the limit column. The moving counterweight drives the spur gear fixed thereon to move, and the moving spur gear drives the meshing gear to rotate forward. The rotating gear drives the threaded rod fixed on the gear to rotate forward, so that the air guide reduces the gas pressure in the sealed chamber. The air pressure in the sealed chamber drops, and the rubber extrusion block that expands and presses against the lens will shrink a certain amount, reducing the extrusion force of the rubber extrusion block on the lens, so that the air guide reduces the gas pressure in the sealed chamber. The air pressure in the sealed chamber pushes the rubber extrusion block to expand, and the lens to be polished in the middle is fixed by the expansion of the rubber extrusion block. When the driving motor When the output shaft reduces the speed, the centrifugal force generated by the rotation decreases, causing the counterweight on the deflection disk to slide toward the outer edge of the deflection disk. The first compression spring compressed on one side of the limit column will be released, pushing the counterweight to slide toward the center of the deflection disk. The moving counterweight drives the spur gear fixed on it to move, and the moving spur gear drives the meshing gear to rotate in the opposite direction. The rotating gear drives the threaded rod fixed on the gear to rotate in the opposite direction, causing the air guide to increase the gas pressure in the sealed chamber. The increase in air pressure in the sealed chamber drives the rubber extrusion block to expand. The expansion of the rubber extrusion block further fixes the lens to be polished in the middle, so that the rubber extrusion block can protect the surface of the lens while ensuring the accuracy of the lens during the polishing process, ensuring that the debris splashed by the grinding wheel during polishing will not cause wear on the surface of the lens, thereby ensuring the clarity of the optical lens after processing.

[0011] Preferably, the air guide includes a straight cylinder, a pushing block, a blocking ring, a blocking column, and a second compression spring. The straight cylinder is fixedly installed on the mounting plate, the straight cylinder is sleeved on the threaded rod, the threaded rod is threadedly connected with a pushing block, the pushing block is slidably connected in the straight cylinder, one end of the straight cylinder is connected to the pipeline, a blocking ring is fixedly installed in the straight cylinder, a blocking column is slidably connected in the straight cylinder, the blocking column abuts against the blocking ring, one end of the blocking column is fixedly installed with a second compression spring, the other end of the second compression spring abuts against the pushing block, and the second compression spring is sleeved on the threaded rod.

[0012] When the gear rotates and drives the threaded rod fixed on the gear to rotate forward, the rotating threaded rod drives the push block threadedly connected thereon to move downward, away from the blocking post on one side, so that the second compression spring between the blocking post and the push block is loosened, reducing the pressure of the blocking post against the blocking ring. Because one end of the straight cylinder is connected to the sealed chamber, the overall air pressure in the sealed chamber is reduced, making it easier for gas to be discharged through the blocking ring, reducing the extrusion force of the rubber extrusion block on the lens. When the gear rotates and drives the threaded rod fixed on the gear to rotate in the opposite direction, the rotating threaded rod drives the push block threadedly connected thereon to move upward, approaching the blocking post on one side, so that the second compression spring between the blocking post and the push block is compressed. The compression increases the pressure of the blocking post against the blocking ring, increasing the overall air pressure in the sealed chamber, making it more difficult for gas to be discharged through the blocking ring, and increasing the extrusion force of the rubber extrusion block on the lens. The rubber extrusion block not only ensures the accuracy of the lens during the grinding process, but also protects the surface of the lens, ensuring that debris splashed by the grinding wheel during grinding does not cause wear on the surface of the lens, thereby ensuring the clarity of the optical lens after processing.

[0013] Preferably, a rotating ring is rotatably connected to the disc cylinder, a rubber disc is fixedly mounted on the rotating ring, the rubber disc is a grid-like structure, and a protective ring is fixedly mounted on the outer ring of the rubber disc.

[0014] The outer protective ring can cover the entire lens raw material, so that when one side of the grinding wheel rotates for grinding, the debris splashed at the outer edge hits the lens surface, causing wear on the lens surface, seriously affecting the overall quality of the product. Therefore, the protective ring covering the lens raw material is used for protection to prevent particles from splashing onto the outer surface of the lens. At the same time, the grinding wheel rotates at high speed, and the friction generated by the rotating grinding wheel will cause wear on the protective ring. Over time, the protective ring will be damaged. By providing a rotating ring, the protective ring is mounted on the rotating ring through a rubber disc, so that when the grinding wheel abuts against the protective ring during rotation, the protective ring is driven to rotate to prevent damage to the protective ring. Of course, the rubber disc is a mesh structure, so that the grinding wheel can squeeze the protective ring when feeding and grinding, causing the protective ring to deform. Of course, the mesh structure of the rubber disc can ensure that the protective ring can still rotate after deformation. The protective ring protects the surface of the lens, ensuring that the debris splashed by the grinding wheel during grinding will not cause wear on the surface of the lens, thereby ensuring the clarity of the optical lens after processing.

[0015] Preferably, the protective ring is made of rubber material and is filled with thin iron sheets. The outer surface of the protective ring is serrated, and a protective ring is fixedly mounted on the bottom of the protective ring. It should be noted that because the protective ring will collide with the grinding wheel for a long time, there are certain requirements for the overall strength of the protective ring. Therefore, thin iron sheets are filled inside the protective ring to ensure the overall strength of the protective ring. At the same time, the protective ring is made of rubber material and has a serrated surface, so that the grinding wheel can push the protective ring to rotate after contact, avoiding damage to the protective ring by the grinding wheel, ensuring that the debris splashed by the grinding wheel during grinding will not cause wear on the surface of the lens, and ensuring the clarity of the optical lens after processing.

[0016] Preferably, a metal rope is provided within the cylindrical disc, one end of which is fixedly mounted to the top of the cylindrical disc. The rubber extrusion block is provided with a protrusion on its surface, which is wrapped with a pull ring. The other end of the metal rope is fixedly mounted to the pull ring. It should be noted that because some lenses may sag inward, the metal rope is required to restrain the rubber extrusion block from bursting due to excessive air pressure, thereby preventing it from breaking and ensuring the life of the device.

[0017] Preferably, an annular recess is provided on the circular window, the thickness of the middle part of the rubber extrusion block is greater than the thickness of the side, a mounting ring is installed on the disc cylinder by screws, and the mounting ring fits into the annular recess after being fixed, and the rubber extrusion block is arranged between the mounting ring and the annular recess, and the rubber extrusion block is away from the sealed chamber.

[0018] During installation, place the rubber extrusion block on the annular depression, cover the rubber extrusion block with a mounting ring, and finally fix the mounting ring with screws. The two protrusions fit together to ensure that the rubber extrusion block can be firmly fixed on the circular window. The thickness of the middle part of the rubber extrusion block is greater than the thickness of the side, ensuring the ductility of the rubber extrusion block while ensuring the hardness of the middle part of the rubber extrusion block against the lens, ensuring that the debris splashed by the grinding wheel during grinding will not cause wear on the surface of the lens, and ensuring the clarity of the optical lens after processing.

[0019] The method for processing an optical lens according to the above-mentioned high-precision optical lens manufacturing device comprises the following steps:

[0020] Step 1: Place the lens material into the housing and use the fixture to push the two oppositely positioned discs closer together;

[0021] Step 2: Turn on the air pump to inflate air into the sealed chamber through the pipe, so that the rubber extrusion block is stretched to press against the lens material in the middle;

[0022] Step 3: When the grinding wheel rotates at high speed to perform rough processing on the lens, the adjustment component controls the air pump to reduce the amount of air entering the disc cylinder;

[0023] Step 4: When the grinding wheel reduces its speed to perform fine processing on the lens, the adjustment component controls the air pump to increase the amount of air entering the disc cylinder.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The air pump pushes air into the disc cylinder to increase the pressure in the sealed chamber, thereby increasing the extrusion force of the rubber extrusion block on the lens, so that the lens is firmly fixed and ensures that the lens will not shake during the grinding process. The rubber extrusion block can protect the surface of the lens while ensuring the accuracy of the lens during the grinding process, ensuring that the debris splashed by the grinding wheel during grinding will not cause wear on the surface of the lens, thereby ensuring the clarity of the optical lens after processing.

[0026] 2. During rough machining, the adjustment component pushes a small amount of air into the disc to reduce the pressure in the sealed chamber and reduce the extrusion force of the rubber extrusion block on the lens. During fine machining, the adjustment component pushes a large amount of air into the disc to increase the pressure in the sealed chamber and increase the extrusion force of the rubber extrusion block on the lens. By controlling the extrusion force of the rubber extrusion block on the lens, the stability of the lens during grinding is ensured, and the outer surface of the lens is protected by the rubber extrusion block.

[0027] 3. When the grinding wheel abuts against the protective ring during rotation, it can drive the protective ring to rotate. Of course, the rubber disc is in a mesh structure, so that the grinding wheel can squeeze the protective ring when feeding and grinding, and the protective ring can be restored to its original state after deformation. The protective ring protects the surface of the lens to prevent the debris splashed by the grinding wheel during grinding from causing wear on the surface of the lens, thereby ensuring the clarity of the optical lens after processing.

The rubber extrusion block 11 is arranged between the mounting ring 30 and the annular recess 29, and the rubber extrusion block 11 is away from the sealed chamber.

[0039] See also Figure 4 、 Figure 5 and Figure 6 A deflection disk 17 is fixedly mounted on the rotating shaft of the driving motor 7. A plurality of evenly distributed long slots 22 are opened on the deflection disk 17. A limit column 18 is fixedly mounted in the long slot 22. A counterweight 20 is sleeved on the limit column 18. The counterweight 20 slides in the long slot 22. A first compression spring 19 sleeved on the limit column 18 abuts against one side of the counterweight 20 and the inner wall of the long slot 22. A straight rack 21 is fixedly mounted on the counterweight 20. A mounting plate 6 is mounted on the driving motor 7. A threaded rod 24 is rotatably connected to the mounting plate 6.

The second compression spring 27 is sleeved on the threaded rod 24.

[0040] A method for processing optical lenses using a high-precision optical lens manufacturing device, see Figure 1 When it is used specifically, the raw materials are batched and poured into the furnace for melting. Finally, the molten glass is poured into the mold and cooled to form lens raw materials. When optical lenses of different shapes and structures are required, polishing equipment is required. Before use, the lens raw materials to be polished need to be placed in the shell 1, and the clamps 2 on both sides are pushed to operate, so that the clamps 2 on both sides push the two oppositely arranged discs 3 to move closer to each other, and align the rubber extrusion block 11 on the disc 3 with the lens raw materials to be polished, and clamp the middle lens raw materials through the rubber extrusion block 11 to fix the middle lens raw materials.

[0041] See also Figure 1 、 Figure 2 and Figure 4 , turn on the air pump 9, and inflate the air into the sealed chamber through the pipe 4. The inflation causes the rubber extrusion block 11 to be stretched and pressed against the lens material in the middle; after the fixation is completed, the air is inflated into the sealed chamber through the air pump 9, so that the gas in the sealed chamber is continuously compressed, and the compressed gas will squeeze the rubber extrusion block 11, and the squeezed rubber extrusion block 11 will further press against the surface of the lens, fixing the lens while protecting the surface of the lens. At this time, start the drive motor 7, and the drive motor 7 drives the grinding wheel 8 on the output shaft to rotate to grind the lens. The outer protective ring 15 can cover the entire lens raw material and protect the lens raw material by the protective ring 15 covering the lens raw material to prevent particles from splashing onto the outer surface of the lens. At the same time, the grinding wheel 8 rotates at a high speed, and the friction generated by the rotating grinding wheel 8 will wear the protective ring 15, which will cause the protective ring 15 to be damaged over a long period of time. By setting a rotating ring 14, the protective ring 15 is installed on the rotating ring 14 through the rubber disc 10, so that when the grinding wheel 8 abuts against the protective ring 12 during rotation, it drives the protective ring 15 to rotate, thereby preventing the protective ring 15 from being damaged.

[0042] See also Figure 1 、 Figure 2 A thin iron sheet 16 is filled inside the protective ring 15 to ensure the overall strength of the protective ring 15. At the same time, the protective ring 15 is made of rubber material and has a toothed surface 13, so that the grinding wheel 8 can push the protective ring 15 to rotate after contact, thereby preventing the grinding wheel 8 from causing damage to the protective ring 15. At the same time, in order to ensure that the rubber extrusion block 11 will not explode due to excessive air pressure, a metal rope 31 is needed to limit the rubber extrusion block 11 to prevent the rubber extrusion block 11 from breaking.

[0043] See also Figure 5 、 Figure 6 and Figure 7When the grinding wheel 8 rotates at high speed to perform rough processing on the lens, the adjusting component controls the air pump 9 to push a small amount of air into the disc cylinder 3; the output shaft of the driving motor 7 drives the deflection disk 17 fixed thereon to rotate. When the output shaft of the driving motor 7 rotates at high speed, the rotation increases the centrifugal force, so that the counterweight block 20 on the deflection disk 17 slides toward the outer edge position of the deflection disk 17 and squeezes the first compression spring 19 sleeved on the limiting column 18. The moving counterweight block 20 drives the spur gear 23 fixed thereon to move, and the moving spur gear 23 drives the meshing gear 23 to rotate forward. The rotating gear 23 drives the threaded rod 24 fixed on the gear 23 to rotate forward. The rotation of the gear 23 drives the threaded rod 24 fixed on the gear 23 to rotate forward. During rotation, the rotating threaded rod 24 drives the pushing block 25 threadedly connected thereon to move downward and away from the blocking column 26 on one side, so that the second compression spring 27 between the blocking column 26 and the pushing block 25 is loosened, reducing the pressure of the blocking column 26 against the blocking ring 28. Because one end of the straight cylinder 5 is connected to the sealed chamber, the overall air pressure in the sealed chamber is reduced, and the gas is more easily discharged through the blocking ring 28, reducing the extrusion force of the rubber extrusion block 11 on the lens. The air pressure in the sealed chamber drops, and the rubber extrusion block 11 that expands and presses against the lens will shrink a certain amount, reducing the extrusion force of the rubber extrusion block 11 on the lens. The air pressure in the sealed chamber pushes the rubber extrusion block 11 to expand, and the lens to be polished in the middle is fixed by the expansion of the rubber extrusion block 11.

[0044] See also Figure 1 、 Figure 6 and Figure 7When the grinding wheel 8 reduces its speed to perform fine processing on the lens, the regulating assembly controls the air pump 9 to push and increase the amount of air entering the disc cylinder 3; the output shaft of the driving motor 7 reduces its speed, and the centrifugal force generated by the rotation decreases, causing the counterweight 20 on the deflection disk 17 to slide toward the center position of the deflection disk 17, and the first compression spring 19 compressed on one side of the limit column 18 will be released, pushing the counterweight 20 to slide toward the center position of the deflection disk 17, and the moving counterweight 20 drives the spur gear 23 fixed thereon to move, and the moving spur gear 23 drives the meshing gear 23 to rotate in the opposite direction, and the rotating gear 23 drives the threaded rod 2 fixed on the gear 23 4 rotates in the opposite direction, and the gear 23 rotates to drive the threaded rod 24 fixed on the gear 23 to rotate in the opposite direction. The rotating threaded rod 24 drives the pushing block 25 threadedly connected thereon to move upward, and approaches the blocking column 26 on one side, so that the second compression spring 27 between the blocking column 26 and the pushing block 25 is compressed. The compression increases the pressure of the blocking column 26 against the blocking ring 28, so that the overall air pressure in the sealed chamber increases, and it is more difficult for the gas to be discharged through the blocking ring 28, thereby increasing the squeezing force of the rubber squeezing block 11 on the lens. The rising air pressure in the sealed chamber drives the rubber squeezing block 11 to expand, and the expansion of the rubber squeezing block 11 further fixes the lens to be polished in the middle.
