Description

Technical Field

[0001] This utility model relates to the field of lens edging technology, specifically a lens edging device. Background Technology

[0002] Optical lenses are mainly made of optical materials such as glass. They are lenses or mirrors made using optical principles to refract, reflect or focus light to achieve the purpose of imaging objects or adjusting light. In the process of manufacturing optical glass lenses, the edges of the lenses need to be ground.

[0003] A Chinese patent with publication number CN213795704U discloses an easily adjustable optical lens side polishing device, including a base plate. Support columns are symmetrically fixedly connected to the upper surface of the base plate, and a connecting plate is fixedly connected between two sets of support columns. A first fixed shaft is rotatably mounted on one side of the connecting plate. A first motor and a hydraulic cylinder are respectively arranged on the upper surface of the base plate. A first rotating shaft is fixedly connected to the output shaft end of the first motor, and a second motor is arranged at the telescopic rod end of the hydraulic cylinder. A second rotating shaft is fixedly connected to the output shaft end of the second motor, and a polishing disc is fixedly connected to one end of the second rotating shaft. The purpose of this invention is to provide an easily adjustable optical lens side polishing device. This device enables the clamping and fixing of optical lenses of different thicknesses during side polishing, thus optimizing existing optical lens side polishing devices.

[0004] During the edging process, the high-speed friction between the lens and the edging tool generates a large amount of heat. However, existing lens edging devices do not have a spray cooling mechanism for timely cooling. As a result, the lens will generate significant thermal stress due to local overheating, leading to lens deformation, bending, or the formation of micro-cracks, which seriously affects the optical performance and processing quality of the lens. Therefore, a lens edging device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve the problems mentioned in the background art, this utility model proposes a lens edging device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A lens edging device of this utility model includes a base, a groove on the base, a T-shaped slider inside the groove, a lead screw rotatably mounted inside the groove, and the lead screw passing through the T-shaped slider. A first motor is mounted on one side wall of the base, and the output end of the first motor is connected to one end of the lead screw. An L-shaped fixing frame is fixed to the top side of the T-shaped slider, and a housing is mounted on the L-shaped fixing frame. A grinding wheel is mounted inside the housing via a rotating shaft. A second motor is mounted on the top side of the housing, and the output end of the second motor is connected to the top end of the rotating shaft. Two bent plates are fixed to the top side of the L-shaped fixing frame, and a hollow tube is fixed to the two bent plates. Three nozzles are mounted on the hollow tube. A housing is mounted on the top side of the T-shaped slider, and the housing is located beside the L-shaped fixing frame. A water pump is mounted on the housing, the inlet of the water pump is connected to a water suction pipe, and the outlet of the water pump is connected to... A conveying pipe, with its other end connected to a hollow tube, is used to edge the lens after it is adsorbed and fixed. During the edge grinding process, a first motor rotates the lead screw, which in turn forces the T-shaped slider to move the edge grinding mechanism and the spraying mechanism until the grinding wheel contacts the edge of the lens. At this point, a second motor rotates the grinding wheel, and a third motor is activated to rotate the drive gear, which in turn forces the driven gear to rotate the rotary table and the adsorbed and fixed lens. This allows for comprehensive edge grinding of the lens. Simultaneously, a water pump is activated to draw water from the housing through a suction pipe and transport it into the hollow tube through the conveying pipe. Finally, the water is sprayed out through nozzles, thus simultaneously grinding and cooling the lens. This effectively reduces the surface temperature of the lens, minimizes the accumulation of thermal stress, and prevents the lens from deforming or cracking due to thermal stress. This ensures that the lens maintains stable material properties during processing and guarantees the quality of the finished lens.

[0007] Preferably, the base has multiple drain outlets, and a water collection tank is installed on the bottom side of the base. A drain pipe is connected to the water collection tank. When using the device, the sprayed water will flow into the water collection tank through the drain outlets. The sprayed water is collected in the water collection tank and can be reused after appropriate treatment, such as filtration and sedimentation, thereby saving water resources.

[0008] Preferably, a rotating platform is rotatably mounted on the base, a first suction cup is fitted on the top side of the rotating platform, an L-shaped support frame is fixedly connected to the base, a sleeve is fixedly connected to the L-shaped support frame, a movable rod is slidably fitted inside the sleeve, a second suction cup is installed at the bottom end of the movable rod, a limiting groove is formed on the sleeve, a sliding rod is inserted into the limiting groove, one end of the sliding rod is fixedly connected to the movable rod, and the other end of the sliding rod is rotatably fitted with a locking nut through a threaded engagement. When adsorbing and fixing the lens, the lens to be edged is first placed on the first... On one suction cup, the lens is firmly adsorbed by the strong suction of the first suction cup. Then, the slide rod moves down along the limiting groove, which in turn moves the second suction cup down as well. When the second suction cup moves down to contact the lens, the slide rod is fixed in the current position by the action of the locking nut. The lens is more firmly adsorbed and fixed by the combined action of the second and first suction cups. This double suction cup fixing method greatly improves the stability of lens fixation, helps to reduce the vibration and displacement of the lens during processing, and thus improves the accuracy and consistency of edge grinding.

[0009] Preferably, a driven gear is mounted on the rotating platform, and a third motor is installed on the base. A driving gear is installed at the output end of the third motor, and the driving gear and the driven gear mesh with each other. When grinding the edge of the lens, the third motor operates to make the driving gear rotate, which in turn forces the driven gear to drive the rotating platform and the lens after it is adsorbed and fixed to rotate, thereby enabling comprehensive edge grinding of the lens edge and greatly improving the efficiency of edge grinding.

[0010] The advantages of this utility model are:

[0011] 1. In the process of edge grinding of lenses, the present invention uses a first electric motor to rotate a lead screw, which in turn forces a T-shaped slider to move the edge grinding mechanism and the spraying mechanism until the grinding wheel comes into contact with the edge of the lens. At this point, a second electric motor rotates the grinding wheel, and a third electric motor is activated to rotate the drive gear, which in turn forces the driven gear to rotate the rotary table and the lens after it is adsorbed and fixed. This allows for comprehensive edge grinding of the lens. Simultaneously, a water pump is activated to draw water from the housing through a water extraction pipe and transport it into the hollow tube through a delivery pipe. Finally, the water is sprayed out through a nozzle, thus enabling the lens to be ground and cooled simultaneously. This effectively reduces the surface temperature of the lens, reduces the accumulation of thermal stress, and prevents the lens from deforming or cracking due to thermal stress. It ensures that the lens maintains stable material properties during processing and guarantees the quality of the processed lens.

[0012] 2. In this invention, when adsorbing and fixing a lens, the lens to be edged is first placed on the first suction cup. The strong suction of the first suction cup firmly adheres the lens. Then, the slide rod moves down along the limiting groove, which in turn moves the second suction cup down as well. When the second suction cup moves down to contact the lens, the slide rod is fixed in the current position by the action of the locking nut. The combined action of the second and first suction cups further secures the lens. This double suction cup fixing method greatly improves the stability of the lens fixation, helps to reduce the vibration and displacement of the lens during processing, and thus improves the accuracy and consistency of the edge grinding.

The output end of the second motor 9 is connected to the top of the rotating shaft. Two bent plates 10 are fixed to the top side of the L-shaped fixing frame 6. Hollow tubes 11 are fixed to the two bent plates 10. Three nozzles 12 are mounted on the hollow tubes 11. A housing 13 is installed on the top side of the T-shaped slider 3 and is located next to the L-shaped fixing frame 6. A water pump 14 is mounted on the housing 13. The input port of the water pump 14 is connected to a water suction pipe 15, and the output port of the water pump 14 is connected to a delivery pipe 16. The other end of the delivery pipe 16 is connected to... On the hollow tube 11, after the lens is adsorbed and fixed, during the edge grinding of the lens, the first motor 4 operates, causing the lead screw 5 to rotate, which in turn forces the T-shaped slider 3 to drive the edge grinding mechanism and the spraying mechanism to move until the grinding wheel 8 moves to contact the edge of the lens. At this time, the second motor 9 operates, causing the grinding wheel 8 to rotate. At the same time, the third motor 20 is started, causing the drive gear 21 to rotate, which in turn forces the driven gear 19 to drive the rotary table 17 and the adsorbed and fixed lens to rotate, thereby enabling comprehensive edge grinding of the lens. Simultaneously, the water pump 14 is started, causing the water in the housing 13 to be drawn out through the water pumping pipe 15 and transported into the hollow tube 11 through the conveying pipe 16. Finally, it is sprayed out through the nozzle 12, thus enabling the lens to be ground and cooled at the same time. This effectively reduces the surface temperature of the lens, reduces the accumulation of thermal stress, and prevents the lens from deforming or cracking due to thermal stress. It ensures that the lens maintains stable material properties during processing and guarantees the quality of the processed lens.

[0022] The base 1 has multiple drain outlets 29, and a water collection tank 30 is installed on the bottom side of the base 1. A drain pipe 31 is connected to the water collection tank 30. When using the device, the sprayed water will flow into the water collection tank 30 through the drain outlets 29. The sprayed water is collected in the water collection tank 30 and can be reused after appropriate treatment, such as filtration and sedimentation, thereby saving water resources.

[0023] Please see Figure 1 and Figure 5 As shown, a rotating platform 17 is rotatably mounted on the base 1. A first suction cup 18 is mounted on the top side of the rotating platform 17. An L-shaped support frame 22 is fixedly connected to the base 1. A sleeve 23 is fixedly connected to the L-shaped support frame 22. A movable rod 24 is slidably mounted inside the sleeve 23. A second suction cup 25 is mounted on the bottom end of the movable rod 24. A limiting groove 26 is formed on the sleeve 23. A sliding rod 27 is inserted into the limiting groove 26. One end of the sliding rod 27 is fixedly connected to the movable rod 24. The other end of the sliding rod 27 is rotatably fitted with a locking nut 28 through a threaded engagement. When adsorbing and fixing the lens, the lens to be edged is first placed on the first... The lens is firmly adsorbed by the strong suction of the first suction cup 18. Then, the slide rod 27 moves down along the limiting groove 26, which in turn moves the second suction cup 25 down as well. When the second suction cup 25 moves down to contact the lens, the slide rod 27 is fixed in the current position by the action of the locking nut 28. The lens is more firmly adsorbed and fixed by the combined action of the second suction cup 25 and the first suction cup 18. This double suction cup fixing method greatly improves the stability of lens fixing, helps to reduce the vibration and displacement of the lens during processing, and thus improves the accuracy and consistency of edge grinding.

[0024] The rotary table 17 is fitted with a driven gear 19, and the base 1 is equipped with a third motor 20. The output end of the third motor 20 is equipped with a driving gear 21, and the driving gear 21 meshes with the driven gear 19. When grinding the lens, the third motor 20 operates to make the driving gear 21 rotate, which in turn forces the driven gear 19 to drive the rotary table 17 and the lens after it is adsorbed and fixed to rotate, thereby enabling comprehensive edge grinding of the lens and greatly improving the efficiency of edge grinding.

[0025] Working Principle: During the edging process, the high-speed friction between the lens and the edging tool generates a large amount of heat. Existing lens edging devices lack a spray cooling mechanism for timely cooling, leading to significant thermal stress due to localized overheating. This can cause lens deformation, bending, or micro-cracks, severely affecting the lens's optical performance and processing quality. Therefore, this lens edging device addresses these issues. When edging a lens, it is first adsorbed and fixed. The lens to be edged is placed on the first suction cup 18, where its strong suction firmly holds the lens. Next, the slide rod 27 moves down along the limiting groove 26, causing the second suction cup 25 to also move down until it contacts the lens. At this point, the locking nut 28 secures the slide rod 27 in its current position. The combined action of the second suction cup 25 and the first suction cup 18 further strengthens the lens's adhesion. This dual-suction cup fixing method significantly improves the stability of the lens fixation and helps reduce lens wear during processing. Vibration and offset during the process improve the accuracy and consistency of edge grinding. After the lens is adsorbed and fixed, during the edge grinding, the first motor 4 operates, causing the lead screw 5 to rotate, which in turn forces the T-shaped slider 3 to move the edge grinding mechanism and the spraying mechanism until the grinding wheel 8 moves to contact the edge of the lens. Then, the second motor 9 operates, causing the grinding wheel 8 to rotate. At the same time, the third motor 20 is started, causing the drive gear 21 to rotate, which in turn forces the driven gear 19 to drive the rotary table 17 and the adsorbed and fixed lens to rotate, thus enabling comprehensive edge grinding of the lens. At the same time, the water pump 14 is started, causing the water in the box 13 to be drawn out through the water pipe 15 and transported into the hollow tube 11 through the conveying pipe 16. Finally, it is sprayed out through the nozzle 12, so that the lens can be ground and cooled at the same time. This can effectively reduce the surface temperature of the lens, reduce the accumulation of thermal stress, and prevent the lens from deforming or cracking due to thermal stress. This ensures that the lens maintains stable material properties during processing and guarantees the quality of the processed lens.
