Description

Technical Field

[0001] This invention relates to the field of optical precision machining technology, and in particular to a multifunctional optical machining support platform. Background Technology

[0002] Polishing and grinding processes for optical components are crucial steps in optical manufacturing. Their core purpose is to ensure that optical components can meet the core functional requirements of light transmission, imaging, reflection / refractive properties by precisely removing surface defects and controlling surface microstructure and precision. If the processing is substandard, the performance of the optical system will be significantly reduced or even fail.

[0003] Optical components require extremely high surface quality and surface accuracy during processing, necessitating precise clamping before polishing. Some optical components are machined using a spiral process, and mass production often involves traditional mechanical clamping. However, mechanical clamping is inefficient, time-consuming, and wasteful of polishing or grinding fluid during the processing of large-diameter optical components. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional optical processing support platform that enables rapid clamping and leveling of optical components, allows for spiral machining during processing, enables free-form surface machining when used with a tool axis tilting head, and can effectively recover excess polishing fluid or grinding fluid during processing.

[0005] To achieve the above objectives, the present invention provides a multifunctional optical processing support platform, including a turntable support base. A torque motor turntable and a liquid recovery assembly are fixedly mounted on the turntable support base. The liquid recovery assembly is located outside the turntable support base. An adsorption support assembly is fixedly mounted on the torque motor turntable. The adsorption support assembly is connected to a vacuum assembly. The adsorption support assembly includes a suction cup transition plate. The top of the suction cup transition plate is fixedly connected to a vacuum suction cup. The vacuum suction cup has sealing ring grooves of different sizes, and a third sealing ring is provided in the sealing ring groove.

[0006] Preferably, the vacuum suction cup is provided with four grooves, each of which is provided with a first threaded hole and a through hole. The through hole is located outside the first threaded hole. The suction cup transition plate is provided with a second threaded hole corresponding to the through hole. The first threaded hole and the through hole are provided with leveling bolts, which are stainless steel hexagonal bolts.

[0007] Preferably, the liquid recovery assembly includes a liquid recovery tank, which is installed on the turntable support. The overlap between the liquid recovery tank and the suction cup transition plate forms a sealed structure, and the liquid recovery tank and the suction cup transition plate do not contact each other. The bottom of the liquid recovery tank is inclined, and a liquid concentration channel is provided at the lowest point of the liquid recovery tank. The liquid concentration channel is connected to the polishing fluid circulation system or the grinding fluid circulation system.

[0008] Preferably, a gas channel is provided at the center of the vacuum suction cup, the suction cup transition plate, and the torque motor turntable. The diameter of the gas channel of the vacuum suction cup and the suction cup transition plate is smaller than that of the gas channel of the torque motor turntable. The bottom of the gas channel of the torque motor turntable is connected to the rotary joint. A positive pressure blowing channel and a negative pressure vacuum channel are provided inside the rotary joint.

[0009] Preferably, a first VA sealing ring is provided between the torque motor turntable and the suction cup transition plate, and a second VA sealing ring is provided between the vacuum suction cup and the suction cup transition plate.

[0010] Therefore, the present invention employs the aforementioned multifunctional optical processing support platform to achieve rapid clamping and leveling of optical components, enabling spiral processing during the processing, and free-form surface processing when combined with the tool axis tilting head, and effectively recovering excess polishing fluid or grinding fluid during the processing.

[0019] Example 1

[0020] like Figures 1 to 3 As shown, this invention provides a multifunctional optical processing support platform, including a turntable support 2. The turntable support 2 has four legs at its bottom, which are bolted together to fix the turntable support 2 to the operating table. A torque motor turntable 1 and a liquid recovery assembly are fixedly mounted on the turntable support 2. The turntable support 2 provides installation space and stable support for the torque motor turntable 1 and the liquid recovery assembly. The torque motor turntable 1 provides stable torque through a torque motor, driving the upper adsorption support assembly and the workpiece to rotate, achieving uniform rotation of the workpiece during the optical processing and ensuring the precision of the optical processing. The torque motor turntable 1 has advantages such as long-term stable precision, high speed, fast dynamic response, and low noise level, making it suitable for precision optical processing.

[0021] The liquid recovery assembly is located outside the torque motor turntable 1. The assembly includes a liquid recovery tank 3, which is mounted on a specific mounting surface of the turntable support 2. The liquid recovery tank 3 and the suction cup transition plate 6 overlap to form a sealed structure, preventing the liquid recovery tank 3 from contacting the suction cup transition plate 6 and thus preventing leakage of polishing fluid or grinding fluid from the overlap and avoiding waste. The bottom of the liquid recovery tank 3 is inclined, and a liquid concentration channel 14 is provided at the lowest point of the liquid recovery tank 3. The liquid concentration channel 14 is connected to the polishing fluid circulation system or the grinding fluid circulation system. The polishing fluid or grinding fluid can flow along the bottom plate of the liquid recovery tank 3 through the liquid concentration channel 14 into the polishing fluid circulation system or the grinding fluid circulation system, recovering excess polishing fluid or grinding fluid and preventing waste caused by the accumulation of polishing fluid or grinding fluid.

[0022] An adsorption support assembly is fixedly installed on the torque motor turntable 1. This assembly is connected to a vacuum assembly, which can adsorb the workpiece onto the adsorption support assembly via vacuum. The adsorption support assembly can adsorb the workpiece and provide stable support. The adsorption support assembly includes a suction cup transition plate 6, the top of which is fixedly connected to a vacuum suction cup 7. The suction cup transition plate 6 provides stable support for the vacuum suction cup 7, which performs vacuum adsorption clamping on the workpiece. The vacuum suction cup 7 has sealing ring grooves of different sizes, and a third sealing ring 10 is installed within each groove. A suitable sealing ring size can be selected based on the size of the optical element 11, creating a sealed structure between the workpiece and the vacuum suction cup 7, facilitating vacuum adsorption clamping of the workpiece.

[0023] The vacuum suction cup 7 has four grooves, each containing a first threaded hole and a through hole. The through hole is located outside the first threaded hole. The suction cup transition plate 6 has a second threaded hole corresponding to the through hole. Leveling bolts 9 are installed in both the first threaded hole and the through hole. A four-point leveling principle is adopted. The leveling bolts 9 in the first threaded hole are used for lifting and leveling, while the leveling bolts 9 in the through hole connect to the second threaded hole. The through hole ensures even force distribution on the leveling bolts 9. By adding four leveling bolts 9 to the traditional four-point leveling system, while leveling is achieved by lifting with these bolts, the additional four leveling bolts 9 simultaneously lock and press down, ensuring that all four legs are fully stressed.

[0024] The leveling bolt 9 is a stainless steel hexagonal bolt with a size of M12×35. This not only effectively prevents the leveling bolt 9 from being corroded by the polishing liquid and thus contaminating the polishing liquid, but also effectively increases the applicability of the vacuum chuck 7, thereby enabling vacuum adsorption and clamping of more types and sizes of optical components 11.

[0025] Gas channels 15 are provided at the center of the vacuum chuck 7, the chuck transition plate 6, and the torque motor turntable 1. The diameter of the gas channels 15 of the vacuum chuck 7 and the chuck transition plate 6 is smaller than that of the gas channel 15 of the torque motor turntable 1. The bottom of the gas channel 15 of the torque motor turntable 1 is connected to the rotary joint 4, and gas enters the gas channels 15 of the vacuum chuck 7, the chuck transition plate 6, and the torque motor turntable 1 through the rotary joint 4. The rotary joint 4 is provided with a positive pressure blowing channel 12 and a negative pressure vacuum channel 13. The positive pressure blowing channel 12 can be quickly disassembled and the turntable can be cleaned after processing. The negative pressure vacuum channel 13 provides effective clamping for optical components 11.

[0026] A first VA sealing ring 5 is provided between the torque motor turntable 1 and the suction cup transition plate 6. The first VA sealing ring 5 can form a sealed space between the torque motor turntable 1 and the suction cup transition plate 6 to prevent air leakage. A second VA sealing ring 8 is provided between the vacuum suction cup 7 and the suction cup transition plate 6. The second VA sealing ring 8 can form a sealed space between the vacuum suction cup 7 and the suction cup transition plate 6 to prevent air leakage.

[0027] When using the multifunctional optical processing support platform provided by the present invention, the third sealing ring 10 adapted to the optical element 11 is installed in the groove of the vacuum suction cup 7. Then, the leveling bolt 9 is adjusted to a suitable position, the optical element 11 is placed on the vacuum suction cup 7, and the negative pressure vacuum channel 13 of the rotary joint 4 extracts the air between the optical element 11 and the vacuum suction cup 7, so that a vacuum space is formed between the optical element 11 and the vacuum suction cup 7, thereby performing vacuum adsorption clamping on the optical element 11.

[0028] After clamping, polishing fluid or grinding fluid is sprayed onto the optical element 11. The torque motor turntable 1 is started, and the torque motor turntable 1 drives the optical element 11 to rotate to complete the processing. Excess polishing fluid or grinding fluid flows into the liquid collection channel 14 through the inclined bottom plate of the liquid recovery tank 3 and enters the polishing fluid circulation system or grinding fluid circulation system, so that the polishing fluid or grinding fluid can be recycled and waste is avoided.

[0029] After polishing, the positive pressure blowing channel 12 blows air between the optical element 11 and the vacuum chuck 7. After removing the optical element 11, the positive pressure blowing channel 12 blows away the debris generated during processing on the vacuum chuck 7.

[0030] Therefore, the present invention employs the aforementioned multifunctional optical processing support platform to achieve rapid clamping and leveling of optical components, enabling spiral processing during the processing, and free-form surface processing when combined with the tool axis tilting head, and effectively recovering excess polishing fluid or grinding fluid during the processing.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
