Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a dustproof optical lens coating machine. Background Technology

[0002] Dustproof optical lens coating machines are primarily used to coat optical lenses to improve their optical performance, such as increasing light transmittance and reducing reflection. High-quality coated lenses have wide applications in optical instruments, photographic equipment, and eyeglasses. This type of coating machine allows for lens coating in a clean environment, ensuring a uniform and pure coating layer on the lens surface, thereby improving lens quality and performance. Current equipment typically requires the following technologies in practical applications:

[0003] 1. High vacuum environment creation technology to reduce the impact of dust and impurities on the coating process;

[0004] 2. Precise evaporation or sputtering control technology for coating materials ensures the thickness and uniformity of the coating layer;

[0005] 3. Highly efficient air filtration technology ensures that the air entering the coating machine is clean;

[0006] 4. Advanced temperature control technology maintains a stable temperature during the coating process;

[0007] 5. Sensitive pressure monitoring and regulation technology ensures stable pressure inside the coating machine.

[0008] Currently, various equipment and methods are used to achieve the function of dustproof optical lens coating. Some manufacturers use enclosed coating machines, which enclose the entire coating process in a small space to reduce the intrusion of external dust.

[0009] For example, a Chinese patent discloses a dustproof coating machine for optical lenses (patent number: CN219526785U). This machine expands the dust collection range through a dust collection pipe network to extract air from the coating chamber for dust removal. Before coating, it removes dust and charged particles from the air inside the coating chamber, reducing the impact of dust and charged particles on the lens coating and improving the coating effect. At the same time, during coating, a dustproof piston blocks the main dust collection pipe to prevent air carrying dust from flowing back, ensuring that the coating process is not affected by dust and charged particles, thus providing dust protection for the entire coating process.

[0010] However, the above method has a prominent problem: in order to improve optical performance and adapt to special environments such as high humidity and high dust, some optical lenses need to be coated on both ends during production. When the above device is used to coat both ends of the lens, it needs to be opened and manually flipped. Opening the device and flipping it will expose the lens to the external environment more, increasing the possibility of dust, moisture and other pollutants adhering to the lens surface and affecting the coating quality. Utility Model Content

[0011] To address the shortcomings of existing technologies, this utility model provides a dustproof optical lens coating machine. It solves the problem that, in order to improve optical performance and adapt to special environments such as high humidity and high dust, some optical lenses need to be coated on both ends during production. The above-mentioned device requires manual flipping when coating both ends of the lens. Opening the device and flipping it will expose the lens to the external environment more, increasing the possibility of dust, moisture and other contaminants adhering to the lens surface and affecting the coating quality.

[0012] To achieve the above objectives, this utility model provides the following technical solution:

[0013] A dustproof optical lens coating machine includes a coating machine body. Inside the coating machine body is a guide mechanism for supporting the sliding spraying of lenses. The guide mechanism includes a rectangular support plate, a guide groove, and a stepped sliding seat. The rectangular support plate is fixedly connected inside the coating machine body. The guide groove is formed inside the rectangular support plate. The stepped sliding seat is slidably connected to the outer surface of the rectangular support plate. Inside the coating machine body is a support mechanism for placing lenses. The support mechanism includes a lens placement platform and a flipping linkage. The lens placement platform is slidably connected inside the coating machine body and rotatably connected inside the stepped sliding seat. The flipping linkage is sleeved on the outer surface of the lens placement platform and inside the guide groove.

[0014] Preferably, a lead screw is rotatably connected to the upper end of the rectangular support plate, the stepped sliding seat is threadedly connected to the outer surface of the lead screw, a drive motor is fixedly connected inside the coating machine body, and the lead screw is sleeved on the outer surface of the drive motor.

[0015] Preferably, a timing pulley is fitted onto the outer surface of the lead screw, and a timing belt is fitted onto the outer surface of the timing pulley.

[0016] Preferably, a slide rail is fixedly connected to the outer surface of the rectangular support plate, the stepped sliding seat is slidably connected to the outer surface of the slide rail, and a first V-shaped clamping block is fixedly connected inside the lens placement stage.

[0017] Preferably, the first V-shaped clamp is rotatably connected to a handle threaded rod inside, and the handle threaded rod is rotatably connected inside the lens placement stage.

[0018] Preferably, a second V-shaped clamp is slidably connected inside the lens placement stage, and the second V-shaped clamp is threadedly connected to the outer surface of the handle thread rod.

[0019] Preferably, the lens placement stage has a through groove inside, and the first V-shaped clamp and the second V-shaped clamp are both slidably connected inside the through groove.

[0020] Preferably, two coating boxes are fixedly connected to the upper part of the coating machine body, and both coating boxes are on the same vertical line as the lens placement table.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The lens placement stage is rotatably connected inside the stepped sliding seat and slides together with the stepped sliding seat. During the sliding process, the flipping connecting rod sleeved on the outer surface of the lens placement stage slides in the guide groove. When the flipping connecting rod passes through the V-shaped groove in the middle section of the guide groove, it drives the lens placement stage to flip. A single sliding operation can complete the double-sided spraying operation. When no processing operation is required, the device can be opened and manually flipped, which simplifies the processing flow, makes the entire coating process smoother and more continuous, reduces the chance of the lens coming into contact with the outside air, reduces the possibility of dust and other impurities adhering to the lens surface, and improves the purity of the coating.

[0023] 2. During the clamping operation, place the optical lens to be coated in the lens placement table, and turn the screw rod of the handle to drive the first V-shaped clamp and the second V-shaped clamp to move closer to each other to clamp the lens, ensuring its stability during the spraying process, ensuring that the lens is fixed in position during the spraying process, and will not shift or shake, thus ensuring the accuracy and uniformity of the coating.

Detailed Implementation

[0030] This application provides a dustproof optical lens coating machine, which effectively solves the problem that some optical lenses require coating on both ends during production to improve optical performance and adapt to special environments such as high humidity and high dust. Previously, the aforementioned device required manual flipping during coating of both ends of the lens, which exposed the lens more to the external environment, increasing the possibility of dust, moisture, and other contaminants adhering to the lens surface and affecting coating quality. The lens placement stage is rotatably connected inside a stepped sliding seat and slides together with it. During the sliding process, a flipping linkage sleeved on the outer surface of the lens placement stage slides in a guide groove. When the flipping linkage passes through a V-shaped groove in the middle of the guide groove, it drives the lens placement stage to flip. A single sliding operation can complete the double-sided spraying operation, eliminating the need for manual flipping during processing. This simplifies the process, making the entire coating process smoother and more continuous, reducing the chance of the lens coming into contact with the outside air, lowering the possibility of dust and other impurities adhering to the lens surface, and improving the purity of the coating.

[0031] Example

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that, in order to improve optical performance and adapt to special environments such as high humidity and high dust, some optical lenses need to be coated at both ends during production. The aforementioned device requires manual flipping during coating at both ends of the lens, which exposes the lens more to the external environment, increasing the possibility of dust, moisture, and other contaminants adhering to the lens surface and affecting the coating quality. The overall concept is as follows: A dustproof optical lens coating machine includes a coating machine body 11. Inside the coating machine body 11 is a guide mechanism for supporting the sliding spraying of the lens. The guide mechanism includes a rectangular support plate 12, a guide groove 13, and a stepped sliding seat 14. The rectangular support plate 12 is fixedly connected inside the coating machine body 11, the guide groove 13 is opened inside the rectangular support plate 12, and the stepped sliding seat 14 is slidably connected to the outer surface of the rectangular support plate 12. The stepped sliding seat 14 sliding on the surface of the rectangular support plate 12 provides support for the sliding spraying of the lens. The guide groove 13 provides support and flipping space when the lens slides. A support mechanism for placing the lens is slidably connected inside the coating machine body 11. The support mechanism includes a lens placement table 15 and a flipping linkage 16. The lens placement table 15 is slidably connected inside the coating machine body 11 and rotatably connected inside the stepped sliding seat 14. The flipping linkage 16 is sleeved on the outer surface of the lens placement table 15 and inside the guide groove 13. During the optical lens coating operation, the lens is placed on the guide groove 13. In the lens placement stage 15, during the spraying process, the lens placement stage 15 is flipped by sliding the flipping link 16 in the guide groove 13. The lens placement stage 15 is rotatably connected to the inside of the stepped sliding seat 14 and slides together with the stepped sliding seat 14. During the sliding process, the flipping link 16, which is sleeved on the outer surface of the lens placement stage 15, slides in the guide groove 13. When the flipping link 16 passes through the V-shaped groove in the middle section of the guide groove 13, the lens placement stage 15 is flipped by the flipping link 16.

[0033] A lead screw 17 is rotatably connected to the upper end of a rectangular support plate 12. A stepped sliding seat 14 is threaded onto the outer surface of the lead screw 17. The rotating lead screw 17 drives the stepped sliding seat 14 to slide for spray coating. A drive motor 18 is fixedly connected inside the coating machine body 11. The lead screw 17 is sleeved on the outer surface of the drive motor 18. A synchronous pulley 19 is sleeved on the outer surface of the lead screw 17, and a synchronous belt 21 is sleeved on the outer surface of the synchronous pulley 19. The drive motor 18 serves as the power source to drive the lead screw 17 to rotate. The lead screw 17 is driven to rotate through the drive motor 18 and the synchronous pulley 19. The movement mechanism drives two lead screws 17 to rotate synchronously, ensuring the stability of the lens placement stage 15 during sliding. A slide rail 22 is fixedly connected to the outer surface of the rectangular support plate 12. A stepped sliding seat 14 is slidably connected to the outer surface of the slide rail 22 and slides on the surface of the slide rail 22. The slide rail 22 restricts the sliding trajectory of the stepped sliding seat 14. A first V-shaped clamp 23 is fixedly connected inside the lens placement stage 15. A handle threaded rod 24 is rotatably connected inside the first V-shaped clamp 23. The handle threaded rod 24 is rotatably connected inside the lens placement stage 15. A second V-shaped clamp 26 is slidably connected inside the mounting platform 15. The second V-shaped clamp 26 is threaded onto the outer surface of the handle threaded rod 24. The first V-shaped clamp 23 and the second V-shaped clamp 26 cooperate to clamp the optical lens, ensuring its stability during the spraying process. By turning the handle threaded rod 24, the first V-shaped clamp 23 and the second V-shaped clamp 26 are moved closer together for clamping. During the clamping operation, the optical lens to be coated is placed in the lens mounting platform 15, and the first V-shaped clamp 26 is moved closer together by turning the handle threaded rod 24. 3. The second V-shaped clamp 26 moves closer to each other to clamp the lens and ensure its stability during the spraying process. The drive motor 18 is started, and the drive motor 18 drives the lead screw 17 to rotate. The lead screw 17 drives the two lead screws 17 to rotate synchronously through the transmission of the synchronous pulley 19 and the synchronous belt 21. When the lead screw 17 rotates, the stepped sliding seat 14, which is threaded to it, slides along the lead screw 17. At the same time, the stepped sliding seat 14 also slides on the slide rail 22. The slide rail 22 restricts the sliding trajectory of the stepped sliding seat 14 to ensure its smooth and accurate sliding.

[0034] The lens placement stage 15 has a through groove 27 inside. The first V-shaped clamp 23 and the second V-shaped clamp 26 are slidably connected inside the through groove 27. The through groove 27 provides sliding space for the first V-shaped clamp 23 and the second V-shaped clamp 26, and the through groove 27 ensures that both ends of the optical lens can be exposed for spray coating operation. Two coating boxes 28 are fixedly connected to the upper end of the coating machine body 11. Both coating boxes 28 are on the same vertical line as the lens placement stage 15. The lower end of the coating box 28 is connected to the spray coating. Using a nozzle, the coating material is sprayed onto the surface of the optical lens through the coating box 28. The two coating boxes 28 correspond to the placement positions of the optical lens before and after flipping, ensuring that coating can be sprayed on both ends. The optical lens to be coated is placed in the lens placement table 15 and clamped and fixed by the first V-shaped clamp 23 and the second V-shaped clamp 26. The lead screw 17 rotates and drives the lens placement table 15 to slide through the stepped sliding seat 14. During the sliding process, the coating material is sprayed onto the surface of the optical lens through the two coating boxes 28.

[0035] To address the problems existing in the prior art, this utility model provides a dustproof optical lens coating machine. The lens placement table 15 is rotatably connected inside the stepped sliding seat 14 and slides together with the stepped sliding seat 14. During the sliding process, the flipping connecting rod 16, which is sleeved on the outer surface of the lens placement table 15, slides in the guide groove 13. When the flipping connecting rod 16 passes through the V-shaped groove in the middle section of the guide groove 13, the lens placement table 15 is flipped by the flipping connecting rod 16. The double-sided spraying operation can be completed in a single sliding operation. There is no need to open the device and manually flip it when processing is not required, which simplifies the processing flow, makes the entire coating process smoother and more continuous, reduces the chance of the lens coming into contact with the outside air, reduces the possibility of dust and other impurities adhering to the lens surface, and improves the purity of the coating.

[0039] Stepped sliding seat 14: Slidably connected to the outer surface of rectangular support plate 12, driving the lens placement stage 15 to slide, providing support and power transmission for the sliding of the lens;

[0040] Lens placement stage 15: Used to place optical lenses to be coated, support the lenses during the coating process and enable sliding and flipping;

[0041] Flipping linkage 16: It is sleeved on the outer surface of the lens placement stage 15 and slides in the guide groove 13, causing the lens placement stage 15 to flip.

[0042] Lead screw 17: When it rotates, it drives the stepped sliding seat 14 to slide, providing power for the sliding of the lens placement stage 15;

[0043] Drive motor 18: As a power source, it drives the lead screw 17 to rotate;

[0048] Handle threaded rod 24: By turning, the first V-shaped clamping block 23 and the second V-shaped clamping block 26 move closer or further apart to achieve clamping operation;

[0049] Second V-shaped clamp 26: Cooperates with first V-shaped clamp 23 to clamp the lens;

[0050] Through slot 27: provides sliding space for the first V-shaped clamp 23 and the second V-shaped clamp 26, ensuring that both ends of the optical lens can be exposed for spray coating operation;

[0051] Coating box 28: Sprays coating material onto the surface of optical lenses to ensure that both ends of the lenses can be coated.

[0052] Working principle:

[0053] The first step involves placing the optical lens to be coated in the lens placement stage 15, where it is clamped and fixed by the first V-shaped clamp 23 and the second V-shaped clamp 26. The lead screw 17 rotates, causing the lens placement stage 15 to slide via the stepped sliding seat 14. During this sliding process, coating material is sprayed onto the surface of the optical lens through the two coating boxes 28. During the clamping operation, the optical lens to be coated is placed in the lens placement stage 15, and the first V-shaped clamp 23 and the second V-shaped clamp are moved by turning the threaded rod 24 of the handle. 26. The lenses are brought closer together and clamped to ensure their stability during the spraying process. The drive motor 18 is started, which drives the lead screw 17 to rotate. The lead screw 17 is driven to rotate synchronously through the transmission of the synchronous pulley 19 and the synchronous belt 21. When the lead screw 17 rotates, the stepped sliding seat 14, which is threaded to it, slides along the lead screw 17. At the same time, the stepped sliding seat 14 also slides on the slide rail 22. The slide rail 22 restricts the sliding trajectory of the stepped sliding seat 14, ensuring its smooth and accurate sliding.

[0054] In the second step, the lens placement stage 15 is rotatably connected inside the stepped sliding seat 14 and slides together with the stepped sliding seat 14. During the sliding process, the flipping connecting rod 16, which is sleeved on the outer surface of the lens placement stage 15, slides in the guide groove 13. When the flipping connecting rod 16 passes through the V-shaped groove in the middle section of the guide groove 13, the lens placement stage 15 is flipped by the flipping connecting rod 16. When the lens placement stage 15 slides with the lens to the position corresponding to the coating box 28, the coating box 28 sprays the coating material onto the surface of the optical lens through the pipe connected to its lower end. Since there are two coating boxes 28, which correspond to the placement positions of the optical lens before and after the flip, it can ensure that both ends of the lens can be sprayed and coated. The through groove 27 opened inside the lens placement stage 15 provides sliding space for the first V-shaped clamp 23 and the second V-shaped clamp 26, and also ensures that both ends of the optical lens can be exposed for spraying and coating.

[0055] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations.
