Description

Technical Field

[0001] This invention relates to the field of lens processing equipment, and in particular to a robotic arm grinding and polishing device for lens processing. Background Technology

[0002] Optical lens polishing is a key process in the manufacture of optical components, aiming to eliminate the microscopic crack layer remaining after lens grinding and improve surface smoothness and optical performance. Its core principle is to use soft tools (such as bitumen or cloth) in conjunction with a polishing slurry based on cerium oxide, which melts and flows the glass surface under mechanical action, filling the cracks and forming an ultra-smooth surface.

[0003] Traditional ring polishing machines, fast polishing machines, and slow polishing machines can only process plane mirrors or spherical mirrors. They need to be selected according to the different process requirements of different lenses, which has the problems of limited applicability and complicated equipment switching. They are difficult to meet the high-efficiency production requirements of diversified lens processing. At the same time, the existing devices have imperfect structures for guiding and collecting debris and waste liquid after polishing, which cannot achieve efficient centralized processing of debris, thus restricting the efficiency and quality improvement of lens processing and making it difficult to meet the requirements of high-efficiency processing. Therefore, a robotic arm polishing device for lens processing is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a robotic arm grinding and polishing device for lens processing, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a robotic arm grinding and polishing device for lens processing, comprising: The machining support base and the mechanical actuator are arranged on the outer side of the machining support base. The mechanical actuator can be flexibly adjusted to adjust the working position, which facilitates the precise machining of lenses at different positions on the disc-shaped fixture, thereby improving the flexibility and coverage of the machining operation. A disc-shaped fastener is rotatably mounted on the upper surface of the processing support base. The upper surface of the disc-shaped fastener has eight guide grooves evenly distributed in a ring. The ends of the guide grooves intersect at the center of the disc-shaped fastener. With the help of the limiting component, the lens can be limited and fixed from multiple directions, adapting to the fixing needs of lenses of various sizes and enhancing the reliability of the fixation. The limiting component is installed inside the guide groove and can be flexibly adjusted according to the lens size to ensure the fixing effect and allow lenses of different specifications to be clamped stably. A grinding mechanism is installed at one end of the mechanical actuator near the processing support. The grinding mechanism includes a grinding disc and a spraying component. The grinding disc performs grinding and polishing operations, and the spraying component accurately delivers the medium, improving processing quality and medium utilization efficiency. A splash guard is installed on the outer edge of the upper surface of the disc-shaped fixture to prevent debris from splashing and maintain a clean processing environment. A fixing base is installed on the upper surface of the center of the disc-shaped fixing component. An optical element support base is installed on the end of the fixing base away from the disc-shaped fixing component, which provides a stable support foundation for the lens and ensures the stability of the lens position during processing. An annular groove is located inside the disc-shaped fixing member near the outer edge. The guide groove is connected to the annular groove. A flow guiding component is installed on the outer side of the disc-shaped fixing member and is connected to the annular groove. This enables the orderly flow and collection of debris, facilitating centralized processing and reducing cleaning difficulty. The lens is set on the processing end face of the optical element support. All components work together to optimize all aspects from fixing and processing to debris handling, thereby improving the overall efficiency and processing quality of lens grinding and polishing. The processing support base is constructed with sturdy metal material to ensure the stability of the mechanical actuator during operation. The mechanical actuator is driven by a high-precision servo motor to achieve flexible movement with multiple degrees of freedom to adapt to the polishing needs of different lenses. The disc-shaped fixing component is rotatably mounted on the processing support base via bearings, ensuring smooth and unobstructed rotation. The inside of the guide groove is lined with low-friction material to reduce the resistance when the limiting component slides. At the same time, the bottom of the guide groove is marked with scale marks to facilitate precise adjustment of the position of the limiting component. In addition, a limiting structure is set to ensure that the disc-shaped fixing component is stable and does not rotate during processing. The limiting structure can be a bolt or a brake structure. The grinding disc is designed to be replaceable to accommodate grinding lenses of different materials. The spraying component is connected to an external coolant system, and the amount and timing of coolant spraying are controlled by a solenoid valve to effectively control the temperature during the grinding process. The anti-splash device is made of transparent high-strength plastic, which not only ensures a clear operating view but also effectively prevents grinding debris from flying and injuring people.

[0006] Preferably, a gripping component is installed on the outer side of the disc-shaped fixing member, and the gripping component is fixedly connected to the disc-shaped fixing member; The gripping component mounted on the outside of the disc-shaped fixture can be fixedly connected to the disc-shaped fixture by welding. First, the welding area on the outside of the disc-shaped fixture is ground to remove the oxide layer and impurities, ensuring a smooth and clean surface. At the same time, the end of the gripping component that contacts the disc-shaped fixture is treated similarly. Then, using appropriate welding rods and welding equipment, welding is performed according to standard welding process parameters, such as welding current, voltage, and welding speed. During the welding process, it is ensured that the weld is uniform and free of defects such as porosity and slag inclusions. After welding, the weld is ground and rust-proofed to firmly fix the gripping component to the outside of the disc-shaped fixture, ensuring that the gripping component will not loosen or fall off during the use of the lens processing robotic arm grinding and polishing device.

[0007] Preferably, a fluid control valve is installed on the outside of the flow guiding component, and the fluid control valve is fixedly connected to the flow guiding component; The fluid control valve, externally mounted on the flow guide component, can be fixed to the flow guide component via a threaded connection. An internal thread is provided at the corresponding position on the flow guide component, and an external thread is provided at the connection end of the fluid control valve. Rotating the fluid control valve achieves a tight connection with the flow guide component. The opening and closing of the fluid control valve can be achieved by manually rotating the valve handle. When it is necessary to open the fluid control valve, rotating the valve handle clockwise connects the internal channel of the fluid control valve with the channel of the flow guide component, allowing liquid to flow. When it is necessary to close the fluid control valve, rotating the valve handle counterclockwise blocks the internal channel of the fluid control valve from the channel of the flow guide component, preventing liquid flow. Clear open / close markings can be provided on the fluid control valve for easy identification and operation by the operator.

[0008] Preferably, the splash-proof device is made of transparent material, and the splash-proof device is fixed to the disc-shaped fixing member by a snap-fit ​​component; The splash guard is made of transparent polycarbonate, which has high transparency and good impact resistance. It is fixed to the disc-shaped fastener through a specially designed snap-fit ​​structure. The disc-shaped fastener has a slot on its edge, and the splash guard has a corresponding protrusion on its edge. During installation, the protrusion is aligned with the slot and pressed firmly to make the protrusion embed into the slot. The friction and shape matching between the slot and the protrusion achieve a stable connection. At the same time, to ensure airtightness, a rubber sealing strip is set on the contact surface between the slot and the protrusion to prevent debris and liquid from splashing out from the connection point during the grinding process.

[0009] Preferably, the limiting member is slidably connected to the guide groove, and the limiting member has a through hole inside; The limiting component is designed to match the shape and size of the guide groove to ensure smooth sliding within it. The limiting component is made of wear-resistant metal or engineering plastic with a certain degree of hardness to extend its service life. When creating through holes inside the limiting component, precision machining techniques, such as drilling or milling, are employed to ensure that the diameter and positional accuracy of the through holes meet design requirements. Fastening components can be installed inside the through holes to securely connect the limiting component to the disc-shaped fixing component or other parts. Simultaneously, corresponding positioning structures or marks are provided at the bottom of the guide groove to facilitate quick and accurate positioning during the installation of the limiting component.

[0010] Preferably, a fastening component is installed inside the through hole, and the lower end face of the fastening component extends to the bottom of the guide groove; The through hole is opened inside the limiting component, and its diameter is slightly larger than that of the fastening component to ensure that the fastening component can be inserted smoothly. The fastening component can adopt a threaded rod design. During installation, the fastening component is inserted from above the through hole, and the fastening component is rotated so that its lower end face fits against the bottom of the guide groove. Under the action of friction, the fastening component is limited and fixed.

[0011] Preferably, a bottom support frame is installed at the bottom of the processing support base, and the bottom support frame is fixedly connected to the processing support base; The bottom support frame and the processing support base can be fixedly connected by welding. Select appropriate welding rods to ensure that the strength of the weld meets the stress requirements of the mechanical actuator grinding and polishing device during operation. Alternatively, bolts can be used for connection. Threaded holes are opened at corresponding positions on the processing support base and the bottom support frame. Bolts, nuts and washers are used to firmly fix the two together to ensure a stable connection and prevent loosening during operation, which would affect the stability of the device and the processing accuracy.

[0012] Preferably, the intersecting ends of the eight guide grooves form an operating groove, and the operating groove is integrally formed with the disc-shaped fixing member; The operating groove is formed simultaneously during the casting or machining of the disc-shaped fixing part. Its dimensional accuracy must meet the requirements for convenient and quick disassembly and assembly of the subsequent limiting part. When it is necessary to remove the limiting part, loosen the fastening parts and then move the limiting part toward the operating groove. When the limiting part is completely moved into the operating groove, the limiting part is disengaged from the guide groove, thus making the disassembly and assembly of the limiting part convenient and quick.

[0013] Preferably, a limiting groove is formed around the outer edge of the fixing seat, and the limiting groove is integrally formed with the fixing seat; When manufacturing the fixed seat, an integral casting process is adopted. First, the metal material is heated to a molten state and then injected into a mold with a pre-designed structure of a surrounding limiting groove. After the metal cools and solidifies, a part with a limiting groove on the outer edge and the limiting groove and the fixed seat are integrally formed. Alternatively, a machining method can be adopted. First, a regular metal block is manufactured as a base, and then a CNC milling machine or other equipment is used to mill the surrounding limiting groove on the outer edge of the metal block according to the design requirements, so as to realize the integral forming of the limiting groove and the fixed seat.

[0014] Preferably, a limiting protrusion is provided on the side of the limiting member near the limiting groove, and the limiting protrusion is integrally formed with the limiting member, and the limiting protrusion is adapted to the limiting groove; During installation, the limiting component is first placed in the guide groove. Since the limiting protrusion is integrally formed with the limiting component, the limiting protrusion is aligned with the limiting groove opened around the outer edge of the fixing base. The limiting component is slowly pushed to slide in the guide groove, so that the limiting protrusion enters the limiting groove, achieving precise positioning and initial fixation. At the same time, a through hole is opened inside the limiting component and a fastening component is installed. The lower end face of the fastening component extends to the bottom of the guide groove. By rotating or tightening the fastening component, it is made to make it in close contact with the bottom of the guide groove, further fixing the position of the limiting component and preventing it from shifting during the grinding process, thus ensuring the stability and precision of the lens processing.

[0015] In summary, compared with the prior art, the present invention provides a robotic arm grinding and polishing device for lens processing, which has the following beneficial effects: This invention utilizes a disc-shaped fixing component with eight evenly distributed guide grooves and limiting elements along a ring. The position of the limiting elements can be flexibly adjusted to accommodate lenses of different sizes, achieving stable fixation and solving the problem of poor lens fixation adaptability and stability. The anti-splash device effectively blocks debris and waste liquid from splashing. Combined with the ring grooves, flow guiding components, and the rotation of the disc-shaped fixing component, centrifugal force allows debris and waste liquid to be guided and collected in an orderly manner, optimizing the processing environment and reducing cleaning and equipment maintenance costs. The fixing base and optical element support base provide stable support for the lens, further ensuring processing accuracy. Through the coordinated operation of all components, the overall device improves the adaptability, stability, and cleanliness of the lens grinding and polishing process, promoting improved lens processing efficiency and quality.

[0027] Please see Figure 1 A bottom support frame 16 is installed at the bottom of the processing support base 1, and the bottom support frame 16 is fixedly connected to the processing support base 1. The bottom support frame 16 and the processing support base 1 can be fixedly connected by welding.

Bolts, nuts and washers are used to secure the two tightly to ensure a stable connection and prevent loosening during operation, which would affect the stability and processing accuracy of the device. The bottom support frame 16, which is fixedly connected to the bottom of the processing support base 1, greatly enhances the structural stability of the grinding and polishing device of the mechanical actuator 3 for processing the lens 8. During operation, the movement of the mechanical actuator 3 and the grinding and polishing of the lens 8 by the grinding mechanism will generate various forces. The bottom support frame 16 provides solid support for the processing support base 1, effectively dispersing and bearing these forces, preventing the processing support base 1 from shaking or displacing due to uneven force, ensuring that the grinding and polishing process can be carried out stably and continuously, and guaranteeing the processing quality of the lens 8.

[0028] Please see Figure 1 and Figure 3 The intersecting ends of the eight guide grooves 14 form an operating groove 18, and the operating groove 18 is integrally formed with the disc-shaped fixing member 17. The operating groove 18 is formed simultaneously during the casting or machining of the disc-shaped fixing part 17. Its dimensional accuracy must meet the requirements for convenient and quick disassembly and assembly of the subsequent limiting part 6. When it is necessary to remove the limiting part 6, loosen the fastening part 7, and then move the limiting part 6 toward the operating groove 18. When the limiting part 6 is completely moved into the operating groove 18, the limiting part 6 disengages from the guide groove 14, thereby making the disassembly and assembly of the limiting part 6 convenient and quick.

[0029] Please see Figure 4 A limiting groove 20 is formed around the outer edge of the fixing base 4, and the limiting groove 20 is integrally formed with the fixing base 4; When manufacturing the fixed base 4, an integral casting process is adopted. First, the metal material is heated to a molten state and then injected into a mold with a pre-designed structure of a surrounding limiting groove 20. After the metal cools and solidifies, a part with a surrounding limiting groove 20 and the fixing base 4 integrally formed can be obtained. Alternatively, a machining method can be adopted. First, a regular metal block is manufactured as a base, and then a CNC milling machine or other equipment is used to mill the surrounding limiting groove 20 on the outer edge of the metal block according to the design requirements, so as to realize the integral forming of the limiting groove 20 and the fixed base 4. The limiting groove 20 and the fixed base 4 are integrally formed, which avoids the problem of loosening or separation caused by the weak connection between the two, making the structure of the whole device more stable and reliable during operation. The one-piece molding structure reduces assembly steps and the number of parts, eliminating the need for additional assembly and adjustment of the limiting groove 20 and the fixing seat 4, thereby improving assembly efficiency and reducing assembly difficulty and cost. The one-piece molding process can better ensure the positional and dimensional accuracy of the limiting groove 20, so that it can be accurately matched with the limiting protrusion 19 and other mating parts, thereby improving the working accuracy of the grinding and polishing device of the mechanical actuator 3 for lens processing 8.

[0030] Please see Figure 4A limiting protrusion 19 is provided on the side of the limiting member 6 near the limiting groove 20, and the limiting protrusion 19 is integrally formed with the limiting member 6, and the limiting protrusion 19 is adapted to the limiting groove 20. During installation, the limiting member 6 is first placed in the guide groove 14. Since the limiting protrusion 19 is integrally formed with the limiting member 6, the limiting protrusion 19 is aligned with the limiting groove 20 that is opened around the outer edge of the fixing seat 4. The limiting member 6 is slowly pushed to slide in the guide groove 14, so that the limiting protrusion 19 enters the limiting groove 20, achieving precise positioning and initial fixation. At the same time, a through hole is opened inside the limiting member 6 and a fastening component 7 is installed. The lower end face of the fastening component 7 extends to the bottom of the guide groove 14. By rotating or tightening the fastening component 7, it is made to make it in close contact with the bottom of the guide groove 14, further fixing the position of the limiting member 6 and preventing it from shifting during the grinding process, ensuring the stability and accuracy of the lens 8 processing. During installation, the engagement of the limiting protrusion 19 and the limiting groove 20 enables the limiting component 6 to be positioned quickly and accurately, improving installation efficiency. During grinding and polishing operations, the matching structure of the two can effectively prevent the limiting component 6 from shaking or shifting unnecessarily within the guide groove 14, ensuring the stability and precision of the grinding mechanism in processing the lens 8, thereby improving the processing quality of the lens 8. At the same time, the one-piece molding design enhances the integrity and robustness of the structure, reduces maintenance and replacement costs caused by loose or damaged parts, and improves the reliability and service life of the device.
