[0034] like Figures 1-7 As shown, a self-feedback-based optical material coating system includes a body 1, an organic cavity 2 formed on the body 1, and a laser coating mechanism, a processing table mechanism, and a movable cleaning mechanism disposed within the cavity 2.

[0035] The processing mechanism includes a processing plate 6, which is fixed to the inner wall of the machine cavity 2, and the processing plate 6 has two or more receiving slots 7.

[0036] The cleaning mechanism includes an electric slide 10, an electric slide plate 11, and a guide rail 12. The guide rail 12 is fixed to the inner wall of the machine cavity 2.

The electric slide plate 11 is slidably connected to the bottom wall of the electric slide 10. A wiping mechanism is provided on the electric slide plate 11.

[0037] Displacement sensor one can detect the displacement of the electric slide 10 in real time and feed it back to the control system. Displacement sensor two can detect the displacement of the electric slide 11 in real time and feed it back to the control system, so that the control system can accurately control both of them.

[0038] To achieve the laser coating function, in a preferred embodiment of the present invention, the laser coating mechanism includes a servo motor 3, a rotating plate 4, and a coating emitter 5. The servo motor 3 is fixed to the inner wall of the cavity 2, the rotating plate 4 is fixed to the output shaft of the servo motor 3, and the coating emitter 5 is fixed to the rotating plate 4. The coating emitter 5 is implemented using existing technology.

The rotation angle and scanning path are automatically planned by the control system to ensure uniform laser incidentness and consistent spot energy, preventing uneven film thickness.

[0039] In order to achieve the function of clamping all lenses, in a preferred embodiment of the present invention, the receiving groove 7 is provided with a clamping mechanism.

[0040] To achieve automatic clamping of all lenses, in a preferred embodiment of the present invention, the electric sliding plate 11 is L-shaped, the processing plate 6 is fixed to the inner wall of the machine cavity 2 via a rotating column 8, the rotating column 8 has a column cavity 15, a trigger rod 9 is slidably connected to the rotating column 8, one end of the trigger rod 9 extends to the outside of the rotating column 8, and the other end extends into the column cavity 15, a force-applying plate 16 is slidably connected to the inner wall of the column cavity 15, the force-applying plate 16 is fixed to the trigger rod 9, the force-applying plate 16 is connected to the inner wall of the column cavity 15 via a spring 17, and two or more airbags 18 are fixed to the inner wall of the column cavity 15, the airbags 18 abut against the force-applying plate 16;

[0042] Airbag 14 and airbag 218 are connected by air tube 19 to form a closed air pressure transmission structure. When the force plate 16 is compressed or released under the action of the vertical section of the electric slide plate 11, it will cause the volume of airbag 218 to change. The gas in airbag 218 flows into or out of airbag 14 through air tube 19, so that airbag 14 will expand or contract synchronously.

[0043] In a preferred embodiment of the present invention, a guide plate 28 is fixedly connected to the bottom wall of the electric slide block 10, a damping slide rail 31 is fixedly connected to the guide plate 28, a rack 29 is slidably connected to the damping slide rail 31, two permanent magnets 30 are fixedly connected to the rack 29, a plate cavity 34 is opened on the electric slide block 11, and the guide plate 28 extends into the plate cavity 34; the damping slide rail 31 enables the rack 29 to maintain its current height when it is not driven by magnetic force.

[0044] The wiping mechanism includes a take-up roller 20, a release roller 21, a movable seat 23, a worm gear 25, and a permanent magnet 27. The take-up roller 20 and the release roller 21 are rotatably connected to the inner wall of the plate cavity 34. The movable seat 23 is slidably connected to the inner wall of the plate cavity 34 and is connected to the inner wall of the plate cavity 34 by a spring 24. Two movable rollers 22 are rotatably connected to the movable seat 23 and extend to the underside of the electric slide plate 11. A cleaning cloth 33 is wound on the release roller 21 and is fixed to the take-up roller 20 after being guided by the two movable rollers 22. A worm gear 32 is fixed to the take-up roller 20. The worm gear 25 is rotatably connected to the inner wall of the plate cavity 34 and meshes with the worm gear 32. A spur gear 26 is fixed to the worm gear 25. The permanent magnet 27 is fixed to the inner wall of the plate cavity 34.

[0045] In order to achieve the limiting function of the rack 29, in a preferred embodiment of the present invention, the guide plate 28 is provided with a groove, and the damping slide rail 31 is fixed to the inner wall of the groove.

[0046] In a preferred embodiment of the present invention, the airbag 14 is annular.

[0047] In order to improve the magnetic force of the permanent magnet 27 and the permanent magnet 30, in a preferred embodiment of the present invention, both the permanent magnet 27 and the permanent magnet 30 contain neodymium, iron and boron, thereby improving their magnetic force and transmission capability.

[0048] In a preferred embodiment of the present invention, the adjacent receiving grooves 7 are spaced equally apart, and the receiving grooves 7 are arranged around the top wall of the processing plate 6.

[0049] A self-feedback-based optical material coating method, which uses the aforementioned self-feedback-based optical material coating system to coat a lens;

[0050] The process includes the following steps: placing each lens individually into the respective receiving slot 7; the electric slide plate 11 moving on the electric slide base 10; the electric slide base 10 moving on the guide rail 12; the wiping mechanism wiping and cleaning the lens; the electric slide plate 11 moving in the opposite direction on the electric slide base 10; and the laser coating mechanism coating the lens.

[0051] Implementation process:

[0052] In the initial state, the vertical section of the electric slide plate 11 abuts against the trigger rod 9, causing the force plate 16 to compress the spring 17, the airbag 18 is not compressed, the electric slide plate 11 is not above the processing plate 6, the rotating plate 4 faces the rotating column 8, the rotating plate 4 and the rotating column 8 are parallel, a permanent magnet 30 near the guide plate 28 is above the permanent magnet 27, the spur gear 26 does not mesh with the rack 29, and the rack 29 abuts against the top wall of the groove.

[0053] Open the door of the machine body 1 and place each lens one by one into its respective receiving slot 7, ensuring the top wall of the lens is higher than the top wall of the processing plate 6. Close the door and use the control system to control the electric slide plate 11 to slide towards the processing plate 6. The damping function of the damping rail 31 allows the rack 29 to maintain its current height, causing the horizontal section of the electric slide plate 11 to move above the processing plate 6. At this time, permanent magnet 27 moves to a position away from the guide plate 28 and below permanent magnet 30. The magnetic attraction of permanent magnet 27 pulls the rack 29 downwards, and the rack 29 meshes with the spur gear 26, controlling the electric slide 10 to rotate along the guide rail 12. After the vertical section of the electric slide plate 11 disengages from the trigger rod 9, the trigger rod 9 loses the thrust of the vertical section of the electric slide plate 11. Under the extension force of the spring 17, the force plate 16 moves towards the airbag 18. The force plate 16 compresses all the airbags 18. Some of the gas in the airbags 18 enters the airbag 14 through the air tube 19. The airbag 14 expands and clamps the lens, thereby realizing automatic clamping of all lenses. There is no need to manually clamp each lens one by one, which improves production efficiency. After the lens is clamped, it prevents mechanical vibration during processing from causing displacement and resulting in a decrease in processing quality.

[0054] When the cleaning cloth 33 comes into contact with the lens, it wipes and cleans the lens, removing oil, dust, and other impurities. The presence of spring 24 allows the movable seat 23 and movable roller 22 to move up and down for cushioning, ensuring the movable roller 22 can smoothly pass over the lens without causing movement jamming. Simultaneously, it allows the cleaning cloth 33 to apply pressure to the lens, improving the cleaning effect. After the electric slide plate 11 moves to contact the rotating column 8, it is controlled to move in the opposite direction to the processing plate 6, causing the horizontal section of the electric slide plate 11 to disengage from above the processing plate 6, preventing the electric slide plate 11 from subsequently obstructing the movement of the coating emitter 5. The electric slide plate 11 moves in the opposite direction to the processing plate 6. During the movement, due to the meshing of spur gear 26 and rack 29, spur gear 26 is driven to rotate by rack 29 when moving horizontally. Spur gear 26 drives worm 25, worm wheel 32, and take-up roller 20 to rotate. Take-up roller 20 collects cleaning cloth 33, and release roller 21 is driven by cleaning cloth 33 to release cleaning cloth 33. Thus, the dusty part of cleaning cloth 33 is collected onto movable roller 22, and the clean part of cleaning cloth 33 is released from release roller 21 between the two movable rollers 22 for the next cleaning of the lens. There is no need to manually replace cleaning cloth 33, which is convenient and quick, reduces equipment downtime, and improves production efficiency. After permanent magnet 27 moves to a position near the guide plate 28 and below permanent magnet 30, the magnetic repulsion of permanent magnet 27 repels permanent magnet 30. Permanent magnet 30 drives the rack 29 to move upward and abut against the top wall of the groove. The rack 29 disengages from the spur gear 26, preventing the take-up roller 20 from rotating and causing the dusty part of the cleaning cloth 33 to be released again when the electric slide plate 11 moves above the processing plate 6.

[0055] Then, control the output shaft of servo motor 3 to rotate, which will drive the coating emitter 5 to rotate, and the coating emitter 5 will coat the lens.

[0056] After the coating is completed, the rotating plate 4 is reset to face the rotating column 8, and the rotating plate 4 and the rotating column 8 are parallel. The electric slide 10 slides back to its original position, causing the vertical section of the electric slide plate 11 to push the trigger rod 9. The trigger rod 9 and the force plate 16 compress the spring 17. Some of the gas in the airbag 14 flows into the airbag 2 18 through the air tube 19. The movement of the force plate 16 causes the airbag 2 18 to re-inflate, and the airbag 14 to shrink. The airbag 14 releases its grip on the lens, so that the subsequent staff can remove the lens from the receiving groove 7.

[0057] The beneficial effects of this invention are as follows:

[0058] The system integrates automated cleaning and coating to improve production efficiency and cleaning quality. It integrates a laser coating mechanism, a processing table mechanism, and a movable cleaning mechanism within the machine body 1. The electric slide 10 and electric slide plate 11 move precisely along the guide rail 12 to realize the entire process of automatic cleaning, clamping, and coating of lenses. The wiping mechanism of the cleaning mechanism can automatically clean the lenses before coating, eliminating the need for manual operation of each lens and significantly improving production efficiency.

[0059] To achieve automatic lens clamping and improve positioning stability and coating accuracy, the clamping mechanism installed in the receiving groove 7 consists of airbag 14, airbag 2 18, air tube 19, force plate 16, and spring 17. After the vertical section of the electric slide plate 11 pushes the trigger rod 9, the force plate 16 applies pressure to airbag 2 18, causing gas to be transmitted through air tube 19 to airbag 14 and expand to clamp the lens, thereby achieving synchronous automatic clamping of all lenses. This structure requires no manual contact, prevents lens displacement, vibration, or detachment, and improves the stability and uniformity of the coating process.

[0060] The cleaning cloth 33 is cyclically renewed, reducing downtime and manual replacement. When the electric slide plate 11 moves in the reverse direction, the spur gear 26 meshes with the spur rack 29, driving the worm gear 25 to rotate, thereby driving the take-up roller 20 to collect the used cleaning cloth 33, while the release roller 21 releases new clean cloth. This self-circulating structure enables the cleaning cloth 33 to be automatically renewed without manual replacement, ensuring that the surface is clean after each wipe and improving the continuous operation capability of the device.

[0061] To achieve magnetic self-feedback control and ensure stable system operation, two permanent magnets 30 are installed on the rack 29, which cooperate with the permanent magnet 27 inside the cavity 34. When the electric slide plate 11 moves to different positions, the attraction or repulsion of the two permanent magnets 30 enables the rack 29 to be automatically attracted or released, thereby completing the self-feedback adjustment of gear transmission engagement and disengagement. This magnetic feedback design can ensure the precise start and stop of the transmission components of the cleaning cloth 33 without the need for external sensor control, avoiding erroneous reset or repeated wiping, and improving the stability of system operation.

[0062] Equipped with a buffer function to avoid jamming and damage during the cleaning process, the movable seat 23 is connected to the inner wall of the plate cavity 34 through the second spring 24, providing a buffer when the cleaning cloth 33 comes into contact with the lens, so that the movable roller 22 can smoothly pass over the lens surface, preventing scratches or damage caused by excessive pressure, and improving cleaning safety and smoothness.

[0063] The components, modules, mechanisms, and devices in this invention that are not described in detail are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. 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 be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
