[0040] The wiping device 4 is disposed above the second cleaning station 23 , and is used to transport the dust-free cloth 101 and clean the surface of the lens 100 .

[0041] The rotary driver 5 is disposed below the second cleaning station 23 and is used to drive the working tool 1 to rotate.

[0042] The storage warehouse 7 is used to store the lens to be cleaned 100 and the cleaned lens 100 . The storage warehouse 7 is provided with a turntable 71 for storing the lens to be cleaned 100 or the cleaned lens 100 .

[0043] The first material feeding mechanism 8 is used for storing and accessing the turntable 71 containing the lens 100 to be cleaned or the cleaned lens 100 in the material storage 7 .

[0044] The second conveying mechanism 9 is used to convey the lens 100 to be cleaned or the cleaned lens 100 between the first conveying mechanism 8 and the loading and unloading station 21 .

[0045] Working method of lens 100 cleaning device:

[0046] A. The operation turntable device 2 is driven to rotate and intermittently stop at the loading and unloading station 21 , the first cleaning station 22 , the second cleaning station 23 and the third cleaning station 24 .

[0047] B. The first feeding mechanism 8 takes out the turntable 71 containing the lens 100 to be cleaned from the storage 7, and the second feeding mechanism 9 transfers the lens 100 to be cleaned in the turntable 71 on the first feeding mechanism 8 to the dedicated working fixture 1 of the loading and unloading station 21.

[0048] C. The lens 100 to be cleaned stops at the first cleaning station 22 along with the work turntable device 2, and the first cleaning device 3 cleans the surface of the lens 100 by spraying gas. Stopping at the second cleaning station 23, the wiping device 4 presses against the surface of the lens 100 with the dust-free cloth 101, and the rotary driver 5 drives the work fixture 1 to rotate and drive the lens 100 to rotate, so as to clean the lens 100. Stopping at the third cleaning station 24, the second cleaning device 6 cleans the surface of the lens 100 by spraying gas. When the lens 100 stops at the loading and unloading station 21 along with the work turntable device 2, the cleaning of the lens 100 is completed.

[0049] D. The second feeding mechanism 9 transfers the cleaned lens 100 in the special working jig 1 located at the loading and unloading station 21 to the turntable 71 on the first feeding mechanism 8, thereby repeatedly cleaning all the lenses 100 to be cleaned in the turntable 71 on the first feeding mechanism 8.

[0050] E. The first feeding mechanism 8 returns the turntable 71 containing the cleaned lens 100 to the storage warehouse 7.

[0051] The present invention automates the cleaning process by cooperating with the operation turntable device 2 and a plurality of cleaning stations, thereby realizing a fully automatic cleaning operation of the lens 100 , reducing manual intervention, greatly improving cleaning efficiency and consistency, and being suitable for mass production.

[0052] A multi-step cleaning process is adopted, through a combination of gas injection and wiping with a dust-free cloth 101, to perform multi-stage cleaning treatments on the lens 100 at the first, second and third cleaning stations respectively, to ensure comprehensive and thorough cleaning of the surface of the lens 100 and improve the cleaning effect.

[0053] The wiping device 4 cooperates with the rotating driver 5 to contact the surface of the lens 100 through the dust-free cloth 101 and perform rotational wiping, which effectively avoids the scratch problem caused by static wiping and ensures the consistency and accuracy of cleaning each area of ​​the lens 100 surface, so that the cleaning process of the lens 100 is precisely controlled.

[0054] The equipped storage warehouse 7, the first feeding mechanism 8 and the second feeding mechanism 9 automatically manage the lenses 100 to be cleaned and cleaned, and can realize fast and accurate loading and unloading of the lenses 100, greatly improving the production efficiency of the equipment, and being suitable for large-scale production line operations.

[0055] The use of dust-free cloth 101 and gas jet cleaning methods in multiple places reduces the possibility of secondary contamination during the cleaning process, and is particularly suitable for cleaning optical lenses 100 with high cleanliness requirements, thereby reducing the risk of contamination.

[0056] like Figure 2 and Figure 4 As shown, the working tool 1 of this embodiment includes a swivel seat 11 , a fixing frame 12 , a pinning base 13 , a clamping driver 14 and a clamping arm 15 .

[0057] The rotating base 11 is provided on the work turntable device 2 .

[0058] The fixing frame 12 is fixed to the rotating base 11 and rotates along with the fixing frame 12 .

[0059] The fixing frame 12 is used to fix the pin-supporting base 13 .

[0060] The clamping driver 14 is fixed in the fixing frame 12 and drives the clamping arm 15 to approach or move away from the pin base 13 .

[0061] The rotary driver 5 is provided with a clamping seat 51, and the rotating seat 11 is provided with a connecting block 111, and the connecting block 111 is connected to the clamping seat 51. The rotary driver 5 is a conventional reduction motor.

[0062] Through the cooperation of the clamping arm 15 and the pin base 13, the lens 100 can be accurately positioned and firmly clamped, ensuring that the lens 100 will not move or deviate during the cleaning process, thereby improving the cleaning accuracy and effect, and enabling the work jig 1 to accurately clamp and fix the lens.

[0063] The clamping driver 14 is used to drive the action of the clamping arm 15, making the clamping operation more flexible and automated. It can be adjusted according to the size and shape of different lenses 100, has strong adaptability, reduces manual intervention and debugging time, and makes the working fixture 1 flexible to drive.

[0064] The clamping design between the swivel seat 11 and the rotary driver 5 achieves a stable connection of the jig, while ensuring that during the cleaning process, the working jig 1 can smoothly and accurately drive the lens 100 to rotate, avoiding the problem of uneven cleaning caused by vibration or shaking.

[0065] The swivel seat 11 is connected to the operating turntable device 2, and the fixed frame 12 rotates integrally with the swivel seat 11. The structure is simple and the modular design is convenient for installation and disassembly, which is conducive to the rapid maintenance and parts replacement of the equipment, and improves the service life and operation efficiency of the equipment.

[0066] The overall structural design combines automated cleaning operations with precise clamping and rotational movements, improving the intelligence level of the equipment. It is suitable for use in lens 100 cleaning tasks that require high precision and high efficiency, combining automation and precision of the operating fixture 1.

[0067] The clamping drive 14 is a conventional pneumatic actuator, a hydraulic actuator or a linear actuator.

[0068] Pneumatic actuators use compressed air to drive the piston to open and close the clamping arm.

[0069] The hydraulic actuator pushes the piston through hydraulic pressure to achieve the opening and closing of the clamping arm.

[0070] Linear actuators use a motor to drive a lead screw to achieve linear movement of the clamping arm.

[0071] like Figure 4 As shown, the working disk device 2 of this embodiment includes a locking mechanism 25 for locking the working fixture 1 , and the locking mechanism 25 includes a locking driver 26 and a locking abutment head 27 .

[0072] The fixing frame 12 is provided with a locking block 121 , and the locking driver 26 drives the locking contact head 27 to contact or separate from the locking block 121 .

[0073] By setting up the locking mechanism 25, when the working jig 1 is rotated to a predetermined position, the locking driver 26 can drive the locking contact head 27 to contact the locking block 121, so that the working jig 1 can be reliably fixed on the corresponding work station to avoid its displacement or loosening during the cleaning process, thereby ensuring the cleaning accuracy and consistency and improving the operating stability of the working jig 1.

[0074] The use of the locking mechanism prevents the working fixture 1 from being displaced due to vibration or other external forces during rotation, thereby effectively improving the safety of the equipment operation.

[0075] The locking driver 26 can accurately control the action of the locking contact head 27 according to the control instructions of the system, realize automatic locking and unlocking of the working fixture 1, reduce manual intervention, improve production efficiency, and realize automatic control.

[0076] The precise cooperation between the locking abutment head 27 and the locking block 121 can reduce the friction of the working fixture 1 when it rotates between cleaning stations, reduce equipment wear, and extend the service life of the equipment.

[0077] like Figure 5 As shown, the first cleaning device 3 and the second cleaning device 6 of this embodiment both include a support frame 31 , an air nozzle 32 and a filter 33 .

[0078] The air nozzle 32 and the filter 33 are both fixed to the support frame 31, so that the air nozzle 32 in the first cleaning device 3 and the second cleaning device 6 can accurately aim at the lens surface for gas spraying, effectively removing dust, impurities, etc. on the lens surface, and cooperate with the filter 33 to ensure the cleanliness of the gas, thereby improving the cleaning effect.

[0079] The air nozzle 32 is connected to the filter 33 through a pipeline. The existence of the filter 33 can extend the service life of the air nozzle 32, reduce the maintenance requirements caused by impurities blocking the air nozzle, and improve the operating stability and continuous working ability of the equipment.

[0080] The filter 33 is connected to an external compressed gas source. By setting the filter 33 to be connected to the external compressed gas source, the filter can effectively filter impurities in the compressed gas, prevent unfiltered gas from causing secondary contamination to the lens, and ensure the supply of high-purity gas source during the cleaning process.

[0081] like Figure 6 As shown, the wiping device 4 of this embodiment includes a mounting frame 41 , a feeding tray 42 , a cloth winding wheel 43 , a belt pulling device 44 , a receiving tray 45 , a holding device 46 and a wiping driver 47 .

[0082] The feed tray 42, cloth winding wheel 43, belt pulling device 44 and receiving tray 45 are all rotatably arranged on the mounting frame 41. The feed tray 42 is used to wind the clean dust-free cloth 101, the cloth winding wheel 43 is used to transport the dust-free cloth 101, the belt pulling device 44 is used to drive the dust-free cloth 101 to move, and the receiving tray 45 is used to wind the used dust-free cloth 101. The setting of the feed tray 42, cloth winding wheel 43 and receiving tray 45 can realize the automatic replacement and recycling of the dust-free cloth 101. The belt pulling device 44 drives the dust-free cloth to move, ensuring that clean cloth is used each time cleaning, avoiding the reuse of contaminated dust-free cloth, and ensuring the cleaning quality. The wiping device 4 can automatically feed, pull and collect materials, which reduces manual intervention, can realize fully automatic cleaning, meet the needs of assembly line production, and improve production efficiency.

[0083] The pressing device 46 is arranged on the mounting frame 41 and is used to press the clean dust-free cloth 101 against the surface of the lens 100. The clean dust-free cloth 101 can be firmly pressed on the surface of the lens 100 through the pressing device 46, and the movement of the wiping driver 47 is coordinated to ensure that the dust-free cloth 101 can be evenly contacted with the surface of the lens 100, thereby improving the wiping effect and removing surface stains.

[0084] The wiping driver 47 drives the mounting frame 41 to move. The wiping driver 47 can flexibly adjust the moving trajectory of the mounting frame 41 according to the shapes and sizes of different lenses 100, ensuring that it meets the cleaning requirements of various lenses 100 and improving the versatility of the equipment.

[0085] The wiper drive 47 is a conventional pneumatic actuator, a hydraulic actuator or a linear actuator.

[0086] The pneumatic actuator uses compressed air to drive the piston to move the mounting bracket 41.

[0087] The hydraulic driver pushes the piston through hydraulic pressure to achieve movement of the mounting frame 41.

[0088] The linear actuator uses a motor to drive a lead screw to achieve linear movement of the mounting frame 41.

[0089] like Figure 6 As shown, the cloth winding wheel 43 of this embodiment includes a tensioner 431 , a first belt winding wheel group 432 and a second belt winding wheel group 433 .

[0090] The tensioner 431 is arranged below the feed tray 42. The tensioner 431 in the cloth wheel 43 can effectively adjust and maintain the tension of the dust-free cloth 101 to prevent the dust-free cloth 101 from being loose or too tight during transportation, thereby ensuring that the dust-free cloth 101 can smoothly and evenly cover the surface of the lens 100 during the wiping process, thereby improving the cleaning effect.

[0091] The first belt winding wheel group 432 and the second belt winding wheel group 433 are respectively arranged between the feeding tray 42 and the receiving tray 45. The first belt winding wheel group 432 and the second belt winding wheel group 433 are reasonably arranged between the feeding tray 42 and the receiving tray 45, which can guide the dust-free cloth 101 to be transmitted smoothly and unimpeded, reduce the jamming phenomenon caused by friction or resistance, and ensure the continuity and stability of the equipment operation.

[0092] The wiping device 4 includes a detergent delivery device 48 , which includes a storage bottle 481 , a delivery tube (not shown) and a tube fixing member 482 .

[0093] The storage bottle 481 is used to store the cleaning agent. The delivery tube is used to deliver the cleaning agent to the surface of the lens 100. The tube fixing member 482 is fixed to the mounting frame 41 and is used to fix the delivery tube. When in use, the cleaning agent stored in the storage bottle 481 is delivered to the delivery tube by pressurizing the storage bottle 481, and drips onto the surface of the lens 100 through the delivery tube, so that the cleaning agent delivery device can dissolve stubborn stains on the surface of the lens 100.

[0094] The cleaning agent is accurately delivered to the surface of the lens 100 through the cleaning agent delivery device, which can effectively dissolve stubborn stains and cooperate with the physical wiping of the dust-free cloth 101 to greatly improve the cleaning effect, especially when stubborn dust or dirt is attached to the surface of the lens 100, which can achieve more thorough cleaning.

[0095] like Figure 7 As shown, the holding device 46 of this embodiment is disposed between the first belt winding wheel set 432 and the second belt winding wheel set 433 .

[0096] The pressing device 46 includes a pressing driver 461 , a pressing platform 462 and an abutment head 463 , wherein the pressing driver 461 is a conventional pneumatic actuator, a hydraulic actuator or a linear actuator.

[0097] The butt 463 is fixed to the pressing platform 462, and the pressing driver 461 drives the pressing platform 462 to approach or move away from the dust-free cloth 101. By driving the pressing platform 462 to approach or move away from the dust-free cloth 101 by the pressing driver 461 in the pressing device 46, the contact force between the dust-free cloth 101 and the surface of the lens 100 can be adjusted, ensuring flexible adjustment for different cleaning needs, thereby improving the controllability of the cleaning effect.

[0098] Preferably, the butt 463 includes a butt body 464, a first elastic resistance member 465 and a second elastic resistance member 466, the butt body 464 is provided with a fixing hole, the first elastic resistance member 465 and the second elastic resistance member 466 are both arranged in the fixing hole, and the second elastic resistance member 466 is sleeved on the outside of the first elastic resistance member 465, and the length of the first elastic resistance member 465 is longer than the length of the second elastic resistance member 466.

[0099] When in use, the pressure-holding driver 461 drives the pressing platform 462 to approach the dust-free cloth 101, and the head 463 presses down as the pressing platform 462 approaches the dust-free cloth 101. The head 463 presses the dust-free cloth 101 against the surface of the lens 100, and the first elastic resistance member 465 presses the dust-free cloth 101 against the center of the surface of the lens 100 first, and cooperates with the rotating driver 5 to drive the working fixture 1 to rotate to clean the center of the surface of the lens 100 first.

[0100] Specifically, the end of the first elastic resistance member 465 is an inclined conical surface, so that the first elastic resistance member 465 gradually increases the area of ​​the dust-free cloth 101 against the surface of the lens 100, so that when cleaning the surface of the lens 100, the cleaning is carried out in the form of expanding from a point to a surface.

[0101] The pressing driver 461 drives the pressing platform 462 to approach the dust-free cloth 101, and the abutting head 463 continues to press down as the pressing platform 462 approaches the dust-free cloth 101, so that the second elastic abutting member 466 presses against the dust-free cloth 101 to the periphery of the surface of the lens 100, thereby cleaning the periphery of the surface of the lens 100. The surface of the lens 100 is cleaned more comprehensively and the cleaning effect is better.

[0102] like Figure 6 As shown, the belt pulling device 44 includes a driving roller 441 and a driven roller 442, and the dust-free cloth 101 is wound between the driving roller 441 and the driven roller 442. The driven roller 442 presses the dust-free cloth 101 against the driving roller 441, and the dust-free cloth 101 is wound around the receiving tray 45 via the driven roller 442. The belt pulling device 44, through the design of the driving roller 441 and the driven roller 442, enables the dust-free cloth 101 to be transmitted stably and smoothly, thereby preventing the dust-free cloth 101 from slipping or deflecting during operation, and ensuring the stability of the cleaning process.

[0103] The driving roller 441 is a motorized roller.

[0104] This embodiment also includes a pressure sensor, an environment monitoring sensor, a vision system, a rotation speed sensor, and a processing system.

[0105] The pressure sensor, the environment monitoring sensor, the vision system, the rotation speed sensor, the wiping device 4 and the rotation driver 5 are all electrically connected to the processing system.

[0106] The pressure sensor is installed on the working jig 1 , and measures the actual pressure value Fm applied by the wiping device 4 to the lens 100 .

[0107] The environmental monitoring sensor is installed on the working turntable device 2 to monitor the environmental data in real time and feed it back to the processing system. The processing system evaluates the value of the environmental compensation factor β through the environmental condition data.

[0108] Environmental data such as temperature, humidity and other values.

[0109] Temperature changes may cause the dust-free cloth 101 or the lens 100 to expand or contract, thereby affecting the wiping pressure and the cleaning effect.

[0110] The humidity change may affect the hygroscopicity of the dust-free cloth 101 . The wet dust-free cloth 101 may become heavier or softer, thereby changing the applied wiping pressure.

[0111] High humidity may cause the material to become wet, affecting the pressure; low humidity may cause the material to become dry, affecting the wiping effect.

[0112] Increasing temperature: decrease β, because high temperature may increase contact pressure or reduce friction.

[0113] Decreased temperature: Increase β, as low temperatures may reduce contact pressure or increase friction.

[0114] Humidity increases: β is decreased because high humidity may cause the dust-free cloth 101 to absorb moisture or the air density to increase.

[0115] Humidity decreases: increase β, because low humidity may reduce the flexibility of the dust-free cloth 101 or generate static electricity.

[0116] The visual system is installed on one side of the work turntable device 2 to obtain the image of the lens 100 to be cleaned and the image of the cleaned lens 100 and feed it back to the processing system. The processing system evaluates the contamination area on the surface of the lens 100 through image segmentation and feature extraction, and obtains the contamination degree CL through the contamination area. The processing system compares the contamination area before and after cleaning to obtain the cleaning effect score CE.

[0117] Specifically, image segmentation is the use of image segmentation techniques by the processing system to separate areas of the lens surface from the background to ensure that only contaminants of the lens are analyzed.

[0118] Feature extraction, through edge detection, texture analysis, brightness, color distribution and other methods, extract features from the image to determine the distribution and density of contaminants on the lens surface.

[0119] Calculation of contamination degree CL:

[0120] Quantification of pollution characteristics: by analyzing the area, distribution and density of pollutants, the pollution degree CL is quantified into a numerical value, generally ranging from 0 to 1.

[0121] 0: means completely clean.

[0122] 1: Indicates that there is a lot of contamination on the lens.

[0123] Cleaning effect score CE calculation:

[0124] Image comparison, the processing system compares the images before and after cleaning and calculates the changes in contaminants before and after cleaning.

[0125] Image comparison methods include:

[0126] Pixel difference, calculates the difference between the corresponding pixel values ​​before and after cleaning to evaluate the removal of pollutants.

[0127] Feature Similarity,The similarity of images before and after cleaning is compared through,feature similarity indices such as the structural similarity index,SSIM.

[0128] The scoring standard is to obtain the cleaning effect score CE based on the degree of pollutant removal, which generally ranges from 0 to 1.

[0129] 0: Indicates that no contaminants were removed and the cleaning effect was extremely poor.

[0130] 1: Indicates that the pollutants are completely removed and the cleaning effect is ideal.

[0131] Example of CE scoring method for cleaning effect scoring:

[0132] Step 1: The contamination area extracted from the image of the lens to be cleaned is 25%, that is, the contamination degree CL=0.25. After cleaning, the processing system detects that the contamination area is 5% through the visual system.

[0133] Step 2: Calculate the cleaning effect score CE by the change in contaminated area.

[0134] The specific cleaning effect score CE calculation formula is: .

[0135] This means that the cleaning effect score CE is 0.8, indicating that there is less residual pollution after cleaning and the cleaning effect is good.

[0136] Dynamically adjust cleaning parameters. If the cleaning effect score CE is low, for example, lower than 0.7, the processing system can automatically adjust the wiping force, wiping times or other cleaning parameters to improve the cleaning effect.

[0137] The processing system helps optimize the cleaning process based on the cleaning effect score CE. If the score is low, the system can automatically increase the actual pressure value F m , increase the number of wiping circles WC to adjust the cleaning intensity.

[0138] The rotation speed sensor is used to measure the number of rotations of the rotary driver 5 . The number of rotations of the rotary driver 5 is fed back by the rotation speed sensor to determine the last wiping number of rotations PWC and the current wiping number of rotations WC.

[0139] The processing system controls the force of the wiping device 4 against the surface of the lens 100 through the dust-free cloth 101 and the number of revolutions of the working fixture 1 driven by the rotary driver 5 according to the wiping force compensation formula, ensuring that the lens 100 is cleaned with a preset wiping pressure under different environmental conditions, so that the cleaning effect of the lens 100 remains consistent.

[0140] Wiping force compensation formula: .

[0141] Among them, F d Wipe pressure for a preset target.

[0142] Actual pressure value F m The actual test value shall prevail.

[0143] α is a sensor error correction factor, and its value range is between 0 and 1. In this embodiment, α is 0.1 as an example.

[0144] The value range of the environmental compensation factor β is between 0 and 0.2. In this embodiment, α is 0.05 as an example.

[0145] Experiments show that at 25°C and 60% humidity, β = 0.1. At 35°C, β needs to be reduced to 0.08, and increased to 0.12 at 15°C. Similarly, when the humidity rises to 80%, β may need to be adjusted to 0.08, and when the humidity drops to 40%, β may increase to 0.15.

[0146] In this way, β can dynamically adapt to changes in temperature and humidity to ensure that the cleaning device always maintains the appropriate compensation force.

[0147] γ is: a dynamic compensation factor, and its value range is between 0 and 1. In this embodiment, α is 1 as an example.

[0148] The pollution level CL is determined according to the pollution level, and the value range is between 0 and 1, where 0 indicates no pollution and 1 indicates severe pollution. In this embodiment, CL is 0.25 as an example.

[0149] The cleaning effect score CE is scored by comparing the images before and after cleaning, and the value range is between 0 and 1, where 0 represents very dirty and 1 represents completely clean. This embodiment takes CL as 0.8 as an example.

[0150] The number of PWC laps last wiped shall be based on the actual number of laps recorded.

[0151] K, λ and μ are adjustment factors, and their value range is between 0 and 0.5. In this embodiment, K is 0.2, λ is 0.1, and μ is 0.05.

[0152] like Figure 8 As shown, the storage warehouse 7 of this embodiment includes a lifter 72 and a storage rack 73. The lifter 72 drives the storage rack 73 to rise and fall.

[0157] The lifter 72 and the material storage and retrieval driver 81 are both conventional pneumatic actuators, hydraulic actuators or linear actuators.

[0158] like Figure 2 As shown, the second feeding mechanism 9 of this embodiment includes a transmission driver 91 and a clamping hand 92. The transmission driver 91 drives the clamping hand 92 to move between the working fixture 1 of the loading and unloading station 21 and the turnover plate 71 of the fixed platform 82. The transmission driver 91 drives the clamping hand 92 to move between the working fixture 1 and the turnover plate 71 of the fixed platform 82, thereby realizing the precise transmission of the lens 100, reducing manual intervention, and improving the overall working efficiency of the equipment. The clamping hand 92 is designed to firmly clamp the lens 100, which can effectively prevent slipping or deviation during the transmission process, ensure the safe transmission of the lens 100, and avoid damage or bumping of the lens 100 during the movement.
