Description

Technical Field

[0001] This invention relates to the field of optical lens polishing, and more specifically, to an optical lens polishing apparatus for experimental analytical instruments. Background Technology

[0002] In experimental analytical instruments, optical lenses are the core components for light transmission and imaging, and their surface quality directly affects the instrument's resolution, accuracy, and signal-to-noise ratio. Therefore, after processing, optical lenses typically require high-precision polishing to eliminate surface defects, reduce roughness, and improve light transmittance.

[0003] First, traditional polishing methods are typically open-plan operations, where polishing compound and coolant are prone to splashing, causing pollution of the working environment, wasting polishing fluid, and increasing production costs. Furthermore, the open environment easily introduces external dust and other impurities, affecting the polishing quality of the lenses.

[0004] Secondly, existing polishing devices often fail to thoroughly clean the lenses after polishing. Polishing paste has strong adhesive properties; if not cleaned properly, it will form stubborn stains after drying, severely affecting the optical performance of the lenses. Current technologies typically lack real-time detection methods for residual polishing paste concentration, often relying on manual experience or fixed cleaning times, leading to insufficient or excessive cleaning (wasting time and water resources).

[0005] Furthermore, in multi-station cyclic polishing processes, different stations may require polishing pastes of different grits for rough or fine polishing. Existing devices struggle to provide precise and independent paste supply for different stations, and the polishing discs often fail to maintain their own cleanliness during cleaning, easily leading to cross-contamination. Therefore, we propose an optical lens polishing device for experimental analytical instruments. Summary of the Invention

[0006] This invention provides an optical lens polishing device for experimental analytical instruments, which solves the technical problems in related technologies, such as the difficulty in achieving precise and independent paste supply for different workstations, and the difficulty in keeping the polishing disc clean during the cleaning process, which can easily lead to cross-contamination.

[0007] The present invention provides an optical lens polishing device for experimental analysis instruments, comprising: a lens polishing machine, wherein the polishing working area of ​​the lens polishing machine is provided with a circulating polishing module; The circulating polishing module includes a circulating turntable, multiple sets of capping drive modules, and multiple sets of closed polishing modules. Each capping drive module is fixedly installed on the polishing work area of ​​the lens polishing machine and corresponds one-to-one with each closed polishing module. The enclosed polishing module includes an upper cover and a lower base box. The end of the cover driving module is fixedly connected to the upper cover. The cover driving module is used to drive the upper cover to press the lower base box to form an enclosed polishing space. The optical lens is enclosed between the lower base box and the upper cover. The upper pressure cap is connected to a paste supply module and a water supply module. The paste supply module is used to supply polishing paste to the optical lens in the enclosed polishing space during the polishing process. A suspension concentration sensor is installed inside the bottom box. The suspension concentration sensor is used to detect the residual concentration of polishing paste in the enclosed polishing space. After polishing is completed, the water supply module rinses the enclosed polishing space with water, and the suspension concentration sensor detects the polishing paste residue until there is no residue. The rotating turntable then moves the next set of enclosed polishing modules to the corresponding pressure cap drive module to continue polishing.

[0008] Furthermore, the capping drive module includes a capping head, which is fixed to the end of the telescopic arm of the capping drive module. The capping head is fixedly connected to the center of the upper wall of the upper cap, and the air supply end supplies air to the upper cap through the capping head for high-speed polishing of the optical lens.

[0009] Furthermore, a pneumatic polishing disc is fixedly installed on the upper inner wall of the upper pressure cap, and the air inlet end of the pneumatic polishing disc is connected to the air supply end in the pressure cap head. A polishing disc is attached to the lower wall of the pneumatic polishing disc, and the polishing disc also has rows of paste outlet holes.

[0010] Furthermore, the paste supply module includes a paste supply connector. The paste supply module is fixed to the upper wall of the capping drive module. The paste supply connector is connected to the paste outlet end of the paste supply module. The paste supply module supplies polishing paste to the paste supply connector through a pump. The mesh size of the polishing paste in each paste supply module is different.

[0011] Furthermore, the ointment supply connector has an ointment guide tube that passes through the upper pressure cap at the ointment outlet end, and the ointment outlet end of the ointment guide tube passes through the pneumatic polishing disc and is interconnected with multiple ointment outlet holes.

[0012] Furthermore, the flushing supply module includes a water supply connector, which is also fixed to the upper wall of the pressure cap drive module. The water supply connector is connected to the water outlet of the flushing supply module, and the flushing supply module supplies water to the water supply connector through a pump.

[0013] Furthermore, a diversion pipe is fixedly installed in a ring on the inner wall of the upper pressure cover. Multiple water spray heads are arrayed on the lower wall of the diversion pipe, and the water spray direction is all towards the center of the lower bottom box. A water guide pipe is connected to the water inlet end of the diversion pipe, and the water guide pipe passes through the upper pressure cover and is connected to the water supply connector.

[0014] Furthermore, an electromagnet is fixedly installed at the center of the lower box, and a lens suction cup is fixedly installed at the end of the telescopic column of the electromagnet. After polishing, the electromagnet drives the lens to descend, causing the optical lens to fall off the polishing disc. This allows water to be directly rinsed onto the optical lens, and during rinsing, the polishing disc is submerged in water and dehydrated under high-speed rotation.

[0015] Furthermore, the bottom wall of the lower box is provided with multiple water drainage holes for draining the optical lenses after rinsing and polishing. The lower wall of the circulating turntable is provided with multiple sets of electric push rods. The telescopic arm of the electric push rod is fixedly provided with a connecting seat. The multiple sets of electric push rods correspond one-to-one with multiple sets of pressure cap drive modules for the combination of the connecting seat and the lower box.

[0016] Furthermore, a water pump is connected to the lower wall of the assembly base, and the water pump is connected to the water pump hole after the assembly base and the lower box are assembled. The water pump is connected to the water pumping end of the water pump.

[0017] The beneficial effects of this invention are as follows: This invention, by setting a suspension concentration sensor in the lower box, can monitor the residual concentration of polishing paste in the enclosed polishing space in real time, thereby accurately controlling the cleaning time. This ensures that the lens is thoroughly cleaned without any residual stains, while avoiding ineffective over-cleaning, thus saving water resources and time costs. By installing an electromagnet and a lens suction cup inside the lower box, the lens is lowered and detached from the polishing disc after polishing, allowing water to directly rinse the lens surface. At the same time, the high-speed rotating polishing disc dehydrates the lens, achieving rapid separation of the lens from the polishing disc and self-cleaning of the polishing disc, thus avoiding cross-contamination.

[0020] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0021] Example 1 like Figures 1-8 As shown, an optical lens polishing device for experimental analytical instruments includes a lens polishing machine 11. The polishing work area of ​​the lens polishing machine 11 is equipped with a circulating polishing module 2. This circulating polishing module 2 is the core unit for realizing multi-station, multi-process continuous polishing operations.

[0022] Specifically, the circulating polishing module 2 includes a circulating turntable 21, multiple sets of capping drive modules 12, and multiple sets of closed polishing modules. Each capping drive module 12 is fixedly installed on the polishing working area of ​​the lens polishing machine 11 and corresponds one-to-one with each closed polishing module. The circulating turntable 21 can rotate in a step-by-step manner in the horizontal plane to sequentially transport the closed polishing modules of different positions to directly below the corresponding capping drive module 12, thereby realizing continuous production, avoiding frequent manual loading and unloading, and significantly improving the batch polishing efficiency of optical lenses for experimental analysis instruments.

[0023] The enclosed polishing module includes an upper pressure cap 22 and a lower base box 23. The end of the pressure cap drive module 12 is fixedly connected to the upper pressure cap 22. The pressure cap drive module 12 can be a cylinder, hydraulic cylinder, or electric push rod 24, used to provide controllable clamping force, driving the upper pressure cap 22 downwards and tightly pressing it against the lower base box 23 to form a closed polishing space. The optical lens is thus enclosed within this space between the lower base box 23 and the upper pressure cap 22. This enclosed structure effectively prevents polishing paste from splashing and external dust contamination during the polishing process, ensuring ultra-high cleanliness of the optical lens surface, which is crucial for the optical performance of the lens used in subsequent experimental analytical instruments.

[0024] The upper pressure cap 22 is connected to a paste supply module 14 and a water supply module 15. The paste supply module 14 is used to quantitatively supply polishing paste to the optical lenses within the enclosed polishing space during the polishing process. A suspension concentration sensor 233 is installed inside the lower base box 23. This sensor operates based on the principles of light scattering or conductivity and is used to detect the residual concentration of polishing paste within the enclosed polishing space in real time. During polishing, the control system dynamically adjusts the supply rate of polishing paste through the paste supply module 14 based on this concentration feedback, ensuring that the polishing area is always at the optimal grinding concentration, thereby achieving a uniform and controllable material removal rate.

[0025] After polishing, the water supply module 15 flushes deionized water or cleaning solution into the enclosed polishing space for cleaning. During this time, the suspension concentration sensor 233 continuously monitors the residual concentration of polishing paste until the concentration reading drops to zero or near zero (i.e., no residue). This closed-loop cleaning control mechanism avoids resource waste caused by over-cleaning and lens contamination caused by insufficient cleaning. After successful cleaning, the capping drive module 12 rises, and the circulating turntable 21 rotates, moving the next set of enclosed polishing modules pre-loaded with unpolished lenses to the corresponding capping drive module 12 for continued polishing. Simultaneously, operators or robotic arms can remove the polished modules and load new lenses.

[0026] The capping drive module 12 includes a capping head 13. The capping head 13 is fixed to the end of the telescopic arm of the capping drive module 12, and is fixedly connected to the center of the upper wall of the upper cap 22. This center-connection method ensures the uniformity of pressure transmission. More importantly, the capping head 13 has a hollow structure, and its air supply end supplies high-pressure clean air into the upper cap 22 through the internal air passage of the capping head 13 to drive the internal polishing elements to rotate at high speed, thereby polishing the optical lens with high efficiency.

[0027] Specifically, a pneumatic polishing disc 221 is fixedly installed on the upper inner wall of the upper pressure cap 22, and the air inlet of the pneumatic polishing disc 221 is sealed to the air supply end in the pressure cap head 13. A polishing disc 222 is attached to the lower wall of the pneumatic polishing disc 221, and the polishing disc 222 also has rows of paste dispensing holes 226. When the high-pressure gas drives the pneumatic polishing disc 221 to rotate, its rotational speed N (rpm) and air supply pressure P (Pascal) have the following proportional relationship: N = k·P, where k is a constant related to the structure of the pneumatic motor. The polishing paste is evenly distributed between the polishing disc 222 and the optical lens through the paste dispensing holes 226, realizing simultaneous operation of paste supply and polishing, ensuring the uniformity of polishing paste distribution, and avoiding scratches caused by local dry grinding.

[0028] Furthermore, the paste supply module 14 includes a paste supply connector 16. The paste supply module 14 is fixed to the upper wall of the capping drive module 12, and the paste supply connector 16 is connected to the paste outlet end of the paste supply module 14. The paste supply module 14 precisely supplies polishing paste to the paste supply connector 16 through an internal micro-metering pump, such as a peristaltic pump or a plunger pump. As a major feature of this invention, each paste supply module 14 contains polishing paste with a different grit. For example, the four stations of the circulating turntable 21 respectively store polishing paste with grits of 400 grit (coarse grinding), 1000 grit (medium grinding), 2000 grit (fine grinding), and 3000 grit (polishing). Through the rotation of the circulating turntable 21, the same optical lens can be sequentially polished with polishing paste of different grits at different stations, realizing a fully automated production line operation from roughing to precision polishing, greatly improving the surface finish of the lens, and making its surface roughness Ra reach the nanometer level, meeting the stringent requirements of high-end analytical instruments for optical components. The relationship between the optical lens material removal rate (MRRMaterial Removal Rate), the polishing paste mesh size (G), and the pressure (F) can be approximately expressed as: ; in This is a comprehensive coefficient, indicating that the larger the mesh number (the finer the particles), the lower the material removal rate under the same pressure, but the better the surface quality.

[0029] The ointment supply connector 16 has an ointment guide tube 225 that passes through the upper pressure cap 22 at its outlet end. The ointment guide tube 225 passes through the pneumatic polishing disc 221 and communicates with multiple ointment outlet holes 226. This embedded tubing design is simple and reliable, preventing external hoses from getting tangled during rotation.

[0030] Regarding the cleaning module, the flushing supply module 15 includes a water supply connector 17. The water supply connector 17 is also fixed to the upper wall of the pressure cap drive module 12 and is connected to the water outlet of the flushing supply module 15. The flushing supply module 15 supplies high-pressure water to the water supply connector 17 via a high-pressure pump.

[0031] A diversion pipe 224 is fixedly installed in a ring on the inner wall of the upper pressure cover 22. Multiple water nozzles are arrayed on the lower wall of the diversion pipe 224, and the spray direction of all the water nozzles is towards the center of the lower base box 23. This centripetal spray design can create a rotating water flow within the enclosed space, effectively flushing dead corners. A water guide pipe 223 is connected to the water inlet end of the diversion pipe 224, and the water guide pipe 223 passes through the upper pressure cover 22 and connects to the water supply connector 17. During flushing, the water flow velocity v and the water supply pressure... Satisfies Bernoulli's equation: ; High-pressure water generates a high-speed jet through a small-diameter nozzle, producing a powerful shearing force that quickly peels off residual polishing paste adhering to the polishing pad 222 and the lens.

[0032] To optimize cleaning and dehydration, an electromagnet 234 is fixedly installed at the center of the lower base box 23. A lens suction cup 231 is fixedly installed at the end of the telescopic column of the electromagnet 234. During polishing, the electromagnet 234 remains extended, lifting the optical lens to a position close to the polishing disc 222. After polishing, the electromagnet 234 is energized, causing the telescopic column and lens suction cup 231 to descend, detaching the optical lens from the pneumatic polishing disc 221. This approach offers two main benefits: First, the descent creates a larger gap between the lens and the polishing disc 222, allowing the water sprayed from the nozzle to directly and extensively wash the surface of the optical lens, thus improving cleaning efficiency. Second, during the later stages of rinsing, the electromagnet 234 remains in a descent state while the pneumatic polishing disc 221 continues to rotate at high speed (idle). At this point, water submerges the polishing disc 222, and the centrifugal force generated by the high-speed rotation can thoroughly remove the polishing paste and water remaining in the pores inside the polishing disc 222, achieving online dehydration and regeneration of the pneumatic polishing disc 221 and preventing microbial growth and blockage.

[0033] In addition, the bottom wall of the lower box 23 has multiple drainage holes 232 for quickly draining wastewater after rinsing and polishing. The lower wall of the circulating turntable 21 is equipped with multiple sets of electric push rods 24. The telescopic arms of the electric push rods 24 are fixedly equipped with assembly seats 27, and each set of electric push rods 24 corresponds one-to-one with a set of cap drive modules 12, for quick assembly and disassembly of the assembly seats 27 and the lower box 23. This design allows the lower box 23 to be separated from its drive and drainage components, facilitating maintenance and replacement.

[0034] Finally, a water suction pipe 25 is connected to the lower wall of the assembly base 27, and the water suction pipe 25 is sealed to the water suction hole 232 after the assembly base 27 and the lower box 23 are assembled. A water pump 26 is connected to the outlet end of the water suction pipe 25. When the water pump 26 is working, a negative pressure is formed at the water suction hole 232. The theoretical water suction flow rate Qpump is related to the pump's vacuum degree H and the pipeline resistance coefficient ζ as follows: ; This negative pressure system is not only used to discharge waste liquid, but also to assist in adsorbing optical lenses during the polishing process, so that they are more stably fixed on the lens suction cup 231.

[0035] Example 2 This embodiment adds a set of intelligent process optimization algorithms based on any of the above embodiments.

[0036] The control system acquires real-time data from the suspension concentration sensor 233 and dynamically optimizes the polishing time t_polish by combining parameters such as the initial surface roughness Ra_init, target roughness Ra_target, and polishing paste characteristic constant K_abrasive of the optical lens. Its core control model is derived from a modified Preston equation. ; Where K_p is the Preston coefficient, P is the pressure, V is the relative velocity, E_a is the activation energy of the polishing paste, R is the gas constant, and T is the temperature. By calculating the current removal rate in real time, the system can accurately predict the remaining time required to reach the target roughness and automatically stop polishing and start the cleaning process at the endpoint. This intelligent control significantly reduces human intervention, ensures the consistency of lens polishing quality between batches, and increases the pass rate to over 99.5%.

[0037] Process Logic: Step S1: Loading and Alignment. Place the optical lens to be polished onto the lens suction cup 231 of the lower base box 23. The rotating turntable 21 rotates, transporting the lower base box 23 containing the lens to directly below the capping drive module 12. The electric push rod 24 rises, causing the assembly seat 27 to assemble with the lower base box 23 and connect to the water suction pipe 25.

[0038] Step S2: Sealing and pressing. The pressure cap drive module 12 drives the upper pressure cap 22 to move downward, pressing it against the lower bottom box 23 to form a closed polishing space. At the same time, the electromagnet 234 pushes the lens up to contact the polishing disc 222.

[0039] Step S3: Supplying polishing compound and polishing. The compound supply module 14 is activated, supplying polishing compound between the lens and the polishing disc 222 through the compound outlet 226. Simultaneously, air is supplied through the capping head 13 to drive the pneumatic polishing disc 221 to rotate for polishing. The suspension concentration sensor 233 monitors the polishing compound concentration in real time.

[0040] Step S4: Determine if the concentration is below the coarse polishing threshold. If the concentration is above the threshold, continue to step S3; if the concentration is below the coarse polishing threshold, it indicates that the effective ingredients of the polishing paste have been exhausted or the predetermined removal amount has been reached, then proceed to step S5.

[0041] Step S5: Stop the paste supply and start flushing. The paste supply module 14 stops the paste supply, and the flushing water supply module 15 starts, spraying water into the enclosed space for cleaning through the spray nozzle of the diversion pipe 224.

[0042] Step S6: Determine if the residual concentration of polishing paste has reached zero. The suspension concentration sensor 233 continuously monitors. If the residual concentration > 0, continue to step S5; if the residual concentration ≈ 0, cleaning is complete, proceed to step S7.

[0043] Step S7: Dehydration and Separation. Electromagnet 234 descends, detaching the lens from polishing disc 222. Pneumatic polishing disc 221 continues to rotate at high speed for centrifugal dehydration. Water pump 26 drains the waste liquid through suction hole 232.

[0044] Step S8: Determine whether all polishing processes are complete. If the result is "No", the rotating turntable 21 rotates to the next station and returns to step S2. If the result is "Yes", proceed to step S9.

[0045] Step S9: Unloading. The capping drive module 12 rises, and the electric push rod 24 descends, separating the lower base box 23 from the assembly seat 27. The operator or robot arm removes the polished optical lens, and the process ends.

[0046] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of the present embodiments, all of which are within the protection scope of the present embodiments.
