Description

Technical Field

[0001] This invention relates to the field of energy storage battery technology, specifically to a precision polishing device for optical lenses. Background Technology

[0002] Optical lenses are core components of optical instruments, imaging equipment, precision testing devices, photolithography equipment, and other equipment. Their surface finish, shape accuracy, and thickness uniformity directly affect the overall optical performance of the device. Nanoscale surface quality and submicron-level shape and position accuracy are now core processing indicators for high-end optical lenses. Polishing, as a precision process at the end of lens manufacturing, is a key step in controlling the yield of finished products. Currently, the mainstream single-sided, double-sided, and single-station grinding and polishing equipment in the industry can no longer meet the modern production requirements of high precision, high efficiency, and low loss.

[0003] The quasi-spherical lens grinding and polishing device, equipment, and processing method, with application number CN202512036865.4, mainly consists of a support, a swing shaft, a base, and a clamping and adsorption positioning assembly. The clamping and adsorption positioning assembly integrates components such as a ejector cylinder, a pressure spring, an adjusting spring, an ejector pin, a vacuum suction seat, a fixture connector, and a fixture. This equipment utilizes a combination of magnetic attraction and vacuum negative pressure to quickly clamp and position the lens. During processing, the lens swings around the quasi-spherical core with the swing shaft, and the concave surface works in conjunction with the lower grinding head to complete the rotary grinding, ensuring that the grinding trajectory precisely matches the curvature of the concave spherical surface of the lens. Simultaneously, the clamping and adsorption positioning assembly has two working states, separating the lens clamping and positioning process from the grinding loading process, ensuring that the grinding pressure is uniformly and stably transmitted along the normal direction of the concave spherical surface. This enables high-precision polishing of concave spherical lenses and offers advantages such as compact structure, flexible pressure adjustment, and strong adaptability.

[0004] However, the equipment does not integrate a single protective structure, polishing fluid diversion structure, and waste liquid recovery structure. During operation, polishing fluid and processing debris are prone to splashing outwards, requiring additional protective facilities and waste liquid pipelines. The overall integration of the equipment is insufficient, and the on-site pipeline layout and equipment arrangement are relatively complex.

[0005] Based on this, this solution proposes "an optical lens precision polishing device" to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a precision polishing device for optical lenses to solve the problem mentioned in the background art that existing market equipment does not have a protective structure.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a precision polishing device for optical lenses, comprising a support frame, a transparent protective cover, a support column, a first motor, and a polishing disc;

The first planetary gears mesh with the inner gears of the second planetary disk. Multiple first planetary gears mesh together with the middle drive gear. The drive gear is rotatably connected to the second planetary disk, and the input shaft above the drive gear is a hexagonal prism structure. The gear meshing transmission method operates smoothly and has a strong load-bearing capacity, which can ensure that the lens rotation speed is uniform and stable, effectively preventing the lens from producing polishing scratches and uneven textures. The hexagonal prism input shaft is accurately positioned and not easy to slip, which greatly improves the transmission reliability between the drive gear and the upper component.

[0020] As a preferred embodiment of the present invention, six material grooves are evenly opened on the surface of the first planetary gear;

The planetary carrier is rotatably connected to four evenly distributed second planetary gears. The bottom of the second planetary gears is fixed to the grinding disc. The planetary carrier is precisely connected to the drive gear through the internal hexagonal groove, which ensures stable torque transmission and convenient assembly and disassembly. The rectangular planetary carrier structure has high strength and is not easily deformed.

Together with the first planetary disk, it forms a multi-stage planetary transmission structure, which can flexibly adjust the revolution and rotation speed of the lens. It is suitable for polishing optical lenses with different materials and different precision requirements. The guide hole on the first planetary disk can realize the smooth delivery of polishing fluid, ensuring continuous lubrication and cooling of the polishing area. The entire transmission structure has low vibration and low noise, reducing the adverse effects of vibration on precision polishing.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0048] Please see Figure 1-12 The technical solution of this invention is: a precision polishing device for optical lenses; comprising a support frame 1, a transparent protective cover 2, a support column 3, a first motor 4, a liquid supply pipeline 5, a threaded rod 6, a drive frame 7, a second motor 8, a first planetary disk 9, a waste liquid pipeline 10, an electric telescopic rod 11, an eccentric disk 12, a liquid collection hopper 13, a second planetary disk 14, a friction disk 15, a drive gear 16, a first planetary gear 17, a material placement trough 18, a flow guide trough 19, a support column 20, a flow guide hole 21, a planetary carrier 22, a second planetary gear 23, and a polishing disk 24;

[0049] The support frame 1 is equipped with a protective mechanism, which includes a transparent protective cover 2, a liquid supply line 5, a waste liquid line 10, and a liquid collection hopper 13. The liquid collection hopper 13 is located above the support frame 1, the waste liquid line 10 is located below the liquid collection hopper 13, the liquid supply line 5 is located on the side of the support frame 1, and the transparent protective cover 2 is located above the support frame 1.

[0050] The support frame 1 is equipped with a lifting mechanism, which includes a support column 3, a first motor 4, a threaded rod 6, a drive frame 7, an electric telescopic rod 11, and an eccentric disc 12. One end of the electric telescopic rod 11 is installed below the support frame 1, and the other end of the electric telescopic rod 11 is installed below the eccentric disc 12. The eccentric disc 12 is located below the support column 3, and the support column 3 is installed above the support frame 1. The first motor 4 is located above the support column 3 and on the side of the threaded rod 6.

[0051] The upper part of the support frame 1 is hinged to a transparent protective cover 2, and U-shaped handles are symmetrically installed on both sides of the protective cover. The hinged structure is easy to open and close, and with the handles, the lens can be quickly put in and taken out, and the equipment can be inspected. The transparent shell allows a direct view of the internal polishing status, while effectively blocking the splashing of polishing liquid and debris, which optimizes the working environment and protects the equipment and operators.

[0052] An electric telescopic rod 11 is rotatably mounted on the bottom of the support frame 1, with its other end rotatably connected to an eccentric disk 12. A support column 3 is fixed above the eccentric disk 12, and the support column 3 can rotate relative to the support frame 1. A first motor 4 is fixed at the bottom of the support frame 1, and the motor output shaft is connected to a threaded rod 6, which rotates in conjunction with the support column 3. The electric telescopic rod 11 is linked with the eccentric disk 12, which can drive the polishing assembly to swing eccentrically and adjust the angle, making the polishing force on the lens more uniform. The first motor 4 drives the threaded rod 6 to rotate, causing the entire component to rise and fall smoothly, and precisely controlling the polishing pressure and contact position.

[0053] A liquid collection hopper 13 is welded and fixed onto the support frame 1. The lower part of the liquid collection hopper has an arc-shaped structure, with an L-shaped waste liquid pipeline 10 connected to its bottom center. The connection section between the pipeline and the liquid collection hopper is designed as a cone shape, and the end of the waste liquid pipeline uses a flange interface. The welded structure ensures the overall stability of the liquid collection hopper, the arc-shaped inner wall guides the waste liquid to collect quickly, and the conical section and L-shaped pipeline provide smooth flow and are not prone to clogging. The flange interface facilitates the connection of external pipelines and liquid storage equipment, realizing centralized collection and transfer of waste liquid.

[0054] A support column 20 with long bolts is fixed to the inner wall of the liquid collection hopper 13, and the second planetary disk 14 is locked and fixed through the column, making disassembly and maintenance very convenient. A friction disk 15 is slidably assembled inside the second planetary disk 14. Multiple strip-shaped guide grooves are opened on the surface of the friction disk, with six semi-circular guide grooves 19 evenly distributed at the center. The sliding friction disk can be finely adjusted to adapt to different lens specifications; the multi-stage guide structure can quickly guide the polishing liquid, ensuring that the liquid evenly covers the processing area, avoiding liquid accumulation, and ensuring stable polishing operations.

[0055] Four evenly arranged first planetary gears 17 are provided above the friction disk 15. These gears mesh with the inner gear ring of the second planetary disk 14 and simultaneously mesh with the central drive gear 16. The drive gear 16 is rotatably mounted on the second planetary disk 14, and its top input shaft is a hexagonal prism structure. The entire gear transmission system operates smoothly and has a strong load-bearing capacity, ensuring uniform lens rotation speed and eliminating polishing scratches and uneven textures. The hexagonal prism shaft provides reliable positioning and is not prone to slippage, significantly improving transmission stability.

[0056] Each first planetary gear 17 has six material slots 18 on its surface, which can hold multiple optical lenses simultaneously, enabling synchronous processing of multiple workpieces and improving production efficiency. The material slots can also limit the movement of the lenses, preventing them from shifting or falling off during processing and ensuring processing accuracy.

[0057] A rectangular planetary carrier 22 is mounted above the drive gear 16. The bottom of the planetary carrier has an internal hexagonal groove that matches the drive gear shaft, ensuring precise alignment and easy assembly / disassembly. Four evenly distributed second planetary gears 23 are rotatably mounted on the planetary carrier, with a polishing disc 24 fixed to the bottom of the gears. The rectangular planetary carrier has high structural strength and is not easily deformed. The second planetary gears drive the polishing disc to rotate synchronously, resulting in small transmission clearance, uniform polishing force, and effectively improving the surface finish of the lens.

[0058] The second planetary gear 23 meshes with the first planetary disk 9, which is rotatably mounted above the planet carrier 22. The disk surface has guide holes 21. A second motor 8 is fixed at the center of the first planetary disk, and its output shaft is rigidly connected to the planet carrier 22. The second motor 8 independently drives the planet carrier 22, forming a multi-stage planetary transmission system with the first planetary disk 9. This system allows for flexible adjustment of the lens's revolution and rotation speeds, adapting to polishing requirements of different materials and precision. The guide holes can deliver polishing fluid, providing lubrication and cooling. The entire transmission structure exhibits low vibration and noise, reducing interference factors in precision machining.

[0059] The first planetary disk 9 is fixedly connected to the drive frame 7. A splash guard is installed on the left side of the drive frame, the main body of which is slidably fitted with the support column 3 and threadedly connected to the threaded rod 6. The liquid supply pipeline 5 is installed on the side of the support frame 1. The pipeline interface is flanged, and the output end adopts a universal bamboo joint pipe with seven water outlets. The threaded rod 6 can drive the drive frame 7 to precisely lift and lower, finely controlling the downward stroke of the polishing disk and the polishing pressure to meet the requirements of ultra-precision machining. The splash guard further enhances the protection effect. The flange pipeline has good sealing performance and is easy to disassemble and assemble. The multiple water outlets can evenly deliver polishing liquid, and the equipment can operate continuously and stably for a long time.

[0060] Working principle: When using an optical lens precision polishing device, open the transparent protective cover 2 hinged above the support frame 1;

[0061] Start the first motor 4. The output shaft of the first motor 4 drives the threaded rod 6 to rotate. The drive frame 7, which is threaded to the threaded rod 6, slides up and down along the bearing column 3, and synchronously drives the first planetary disk 9, the second motor 8, the planetary carrier 22, the second planetary gear 23 and the grinding disk 24 to be lifted as a whole.

[0062] The electric telescopic rod 11 below the support frame 1 extends and retracts, pushing the eccentric disk 12 to deflect. The eccentric disk 12 drives the fixed support column 3 above to rotate relative to the support frame 1, causing the entire upper polishing assembly to eccentrically swing, exposing part of the first planetary gear 17.

[0063] The optical lenses to be processed are placed sequentially in the material groove 18 on the surface of the first planetary gear 17. The material groove 18 is used to position the lenses to prevent them from shifting or falling off during the polishing process. After the lenses are placed;

[0064] The reverse drive electric telescopic rod 11 and the first motor 4 reset the bearing column 3 and the drive frame 7. The planetary carrier 22 is connected to the drive gear 16 through the internal hexagonal groove. Then the transparent protective cover 2 is closed. The transparent protective cover 2 can block the splashing of polishing liquid and debris.

[0065] The second motor 8 is started, and its output shaft drives the planetary carrier 22 to rotate, causing the entire gear transmission structure to operate synchronously.

[0066] The planetary carrier 22 drives four second planetary gears 23 to revolve around the center. The second planetary gears 23 mesh with the first planetary disk 9 to generate rotation. The polishing disk 24 fixed at the bottom of the second planetary gears 23 then performs a combined motion of revolution and rotation to polish the lens in the material trough 18.

[0067] The planetary carrier 22 drives the drive gear 16 to rotate through the internal hexagonal structure. The drive gear 16 meshes with four first planetary gears 17. The first planetary gears 17 then mesh with the inner gear of the second planetary disk 14 to drive the transmission, so that the first planetary gears 17 carrying the lens rotate synchronously, realizing the autonomous rotation of the lens. The first planetary gears 17 can slide and rub on the friction disk 15 to perform polishing operations.

[0068] At the same time, the external polishing liquid is connected to the liquid supply line 5 on the side of the support frame 1. The polishing liquid flows out through multiple universal bamboo joint tubes of the liquid supply line 5, passes through the guide hole 21 on the first planetary disk 9 in sequence, wets the polishing parts, and is evenly delivered to the polishing contact surface, playing the role of lubrication, cooling and assisting polishing.

[0069] The polishing fluid then flows through the strip-shaped guide groove and six semi-circular guide channels 19 on the surface of the friction disk 15, and falls into the collection hopper 13. The arc-shaped inner wall of the collection hopper 13 guides the waste fluid to the bottom, and flows into the L-shaped waste fluid pipeline 10 through the conical connecting section, and finally discharges from the flange interface of the waste fluid pipeline 10, completing the unified collection and transfer of waste fluid. The collection hopper 13 is fixed to the second planetary disk 14 by the support column 20 and long bolts, which makes the structure stable and convenient for disassembly and maintenance.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
