[0002] Optical dome films are functional thin film materials specifically used for coating the surface of optical domes. Their performance must match the application scenarios and requirements of the optical dome. As a protective cover for optical components, the film itself must have extremely high visible light transmittance to avoid affecting the imaging quality of the optical system.

[0003] According to the announcement CN214652470U, a film conveying mechanism for coating optical domes includes a support plate. From top to bottom, the support plate is sequentially equipped with a film feeding mechanism, a film tensioning mechanism, a first transition mechanism, a mold coating mechanism, a second transition mechanism, and a film receiving mechanism. The film feeding mechanism includes two first limiting plates, symmetrically fixed to the upper surface of the support plate. A first support shaft is positioned between the two first limiting plates, and a feeding roller wound with film is sleeved on the first support shaft. The film tensioning mechanism includes two first fixing plates, symmetrically fixed to the upper surface of the support plate. A connecting plate is positioned at the upper end between the two first fixing plates, and a second support shaft is positioned at the lower end between the two first fixing plates. A first telescopic cylinder is positioned on the lower surface of the connecting plate. This invention has a simple structure, is easy to operate, and can convey film and coat optical domes.

[0004] The above-mentioned device is easy to operate and can transport films and coat optical domes. According to the instruction manual and the accompanying drawings, the distance between the two sets of transition rollers in the first transition mechanism and the second transition mechanism is fixed. However, different types of films, such as thickness, hardness, elasticity and width, have different requirements for the transport path. Utility Model Content

However, different types of films, such as thickness, hardness, elasticity and width, have different requirements for the transport path. Therefore, this utility model provides a film transport mechanism for coating optical domes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a film conveying mechanism for coating an optical dome, comprising a support plate, a coating mechanism at the top of the support plate, a receiving mechanism at the top of the support plate, a tensioning mechanism at the top of the support plate, a first mounting plate fixedly mounted at the top of the support plate, a second mounting plate fixedly mounted at the top of the support plate, a guide roller rotatably connected between the first and second mounting plates, a slider slidably connected between the first and second mounting plates, and a guide roller rotatably connected between the middle of the slider, a through groove through one end of the second mounting plate, a connecting rod slidably connected inside the through groove, a slider and a connecting rod fixedly mounted at one end, and a U-shaped block slidably connected to one end of the second mounting plate, and the U-shaped block and the connecting rod fixedly mounted.

[0007] As a further embodiment of this utility model: the mounting plate has grooves symmetrically opened at both ends, and limiting rods for limiting are symmetrically fixedly installed inside the grooves; the U-shaped block has a cavity at one end, and an L-shaped rod is slidably connected inside the cavity; the L-shaped rod is adapted to the limiting groove in the middle of the two sets of limiting rods.

[0008] As a further embodiment of this utility model: a pressing block is slidably connected to one end of the U-shaped block, and the pressing block is fixedly installed with the L-shaped rod through the cavity. A reset spring is fixedly installed inside the cavity, and the reset spring is set outside the pressing block.

[0009] As a further embodiment of this utility model: both ends of the mounting plate one and the mounting plate two are fixedly installed with fixing blocks, and a sliding block is slidably connected inside the fixing block, and the sliding block is sleeved on the outer periphery of the guide roller one, and a limit ring is rotatably connected to one end of the sliding block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a pressing block to drive an L-shaped rod to disengage from a limiting groove, which can easily push a U-shaped block to slide via a connecting rod, thereby quickly adjusting the distance between guide roller two and guide roller one. This adapts to films of different thicknesses and hardnesses. After adjustment, a reset spring automatically pushes the L-shaped rod into the limiting groove, firmly fixing the position of the guide roller. The operation requires no complicated tools, is convenient and efficient, and can flexibly meet the different needs of different types of films for the conveying path. It avoids conveying discomfort caused by fixed spacing, and improves the versatility of the mechanism and the stability of film conveying.

[0014] This invention allows the limiting block to disengage from the limiting rack by pulling the pulling rod, and pushes the sliding block to make the limiting ring fit the edge of the film, achieving precise adaptation of films of different widths. After adjustment, the reset spring automatically pushes the limiting block into the rack for fixation. The operation is simple and efficient. The limiting ring can stably constrain the edge of the film, effectively preventing deviation during transportation and ensuring that films of different widths are transported stably along the preset path. It can adapt to diverse film width requirements without complicated operations, improving the versatility and transportation stability of the mechanism and meeting the requirements of differentiated paths.

A cavity 15 is opened at one end of U-shaped block 12, and an L-shaped rod 16 is slidably connected inside the cavity 15. The L-shaped rod 16 is adapted to the limiting groove in the middle of the two sets of limiting rods 14.

[0024] The above-mentioned scheme adopts the following components: support plate 1, film covering mechanism 2, material receiving mechanism 3, and tensioning mechanism 4 are all prior art referenced in the prior art documents and are not described in detail in this application. Mounting plate 1 5 and mounting plate 2 6 are both made of steel. Guide roller 1 7 and guide roller 2 8 are made of No. 45 steel with chrome plating. Slider 9 is made of wear-resistant cast iron. Connecting rod 11 is made of stainless steel. U-shaped block 12 is made of Q235 steel. Limiting rod 14 is made of No. 45 steel with quenching. L-shaped rod 16 is made of 65Mn spring steel. Wear-resistant cast iron slider 9 drives guide roller 2 8 to slide. Stainless steel connecting rod 11 connects slider 9 and U-shaped block 12. Moving U-shaped block 12 can adjust the distance between guide roller 1 7 and guide roller 2 8. 65Mn L-shaped rod 16 is fixed in position in the groove of limiting rod 14, and the fit is stable. Chrome-plated guide roller 1 7 and guide roller 2 8 are wear-resistant. Slider 9 slides smoothly. The overall structure realizes flexible adjustment of guide distance, reliable locking, and adaptability to the conveying needs of materials of different specifications.

[0025] Reference Figures 1 to 5 A pressing block 18 is slidably connected to one end of a U-shaped block 12, and the pressing block 18 is fixedly installed through a cavity 15 and an L-shaped rod 16. A return spring 17 is fixedly installed inside the cavity 15 and is sleeved on the outside of the pressing block 18. Fixing blocks 19 are fixedly installed at both ends of mounting plates 15 and 2. A sliding block 20 is slidably connected inside the fixing block 19 and is sleeved on the outer periphery of the guide roller 7. A limit ring 21 is rotatably connected to one end of the sliding block 20. A limiting rack 22 is fixedly installed at the top of the moving block 20. A cavity 23 is formed inside the fixed block 19. A limiting insert 24 for limiting is slidably connected inside the cavity 23. The limiting insert 24 is adapted to the tooth groove of the limiting rack 22. A reset spring 26 is fixedly installed inside the cavity 23. The reset spring 26 is fixedly installed with the limiting insert 24. A pull rod 25 is slidably connected at the top of the fixed block 19. The pull rod 25 passes through the cavity 23 and is fixedly installed with the limiting insert 24.

[0026] The above scheme is adopted: the pressing block 18 is made of ABS plastic, the return spring 17 is made of 65Mn spring steel, the fixing block 19 is made of Q235 steel, the sliding block 20 is made of wear-resistant cast iron, the limiting ring 21 is made of No. 45 steel, the limiting rack 22 is made of 20CrMnTi, the limiting insert 24 is made of 65Mn spring steel, the second return spring 26 is made of 65Mn, and the pull rod 25 is made of stainless steel. The ABS pressing block 18 drives the 65Mn L-shaped rod 16 to compress the return spring 17, which can release the U-shaped block 12 from locking. The 20CrMnTi limiting rack 22 is linked with the sliding block 20. The 65Mn limiting insert 24 is inserted into the tooth groove under the action of the second return spring 26 to fix the position of the guide roller 7. The stainless steel pull rod 25 can be unlocked and adjusted. The overall cooperation makes it convenient to adjust the distance between the guide roller 7 and the guide roller 8. The double locking structure ensures the stability of the conveying and is suitable for various material specifications.

[0027] The working principle of this utility model is as follows: When the film conveying mechanism is working, the distance between guide roller 7 and guide roller 8 is adjusted to adapt to different types of films. Pressing the pressing block 18 at one end of the U-shaped block 12 compresses the reset spring 17 and drives the L-shaped rod 16 to slide along the cavity 15, causing the L-shaped rod 16 to disengage from the limiting groove in the middle of the two sets of limiting rods 14 in the groove 13, releasing the fixation on the U-shaped block 12, and pushing the U-shaped block 12 to slide along the mounting plate 6. The U-shaped block 12 drives the slider 9 to slide between the mounting plate 5 and the mounting plate 6 through the connecting rod 11. The guide roller 8 in the middle of the slider 9 moves with the slider 9, changing the distance with the guide roller 7 to adapt to different thicknesses. After adjusting the spacing of films of different widths and hardness, release the pressing block 18. The reset spring 17 will reset and push the L-shaped rod 16 back into the corresponding limiting groove, fixing the position of the guide roller 8. For films of different widths, pull the pulling rod 25 at the top of the fixing block 19, causing the limiting insert 24 to compress the reset spring 26 and disengage from the tooth groove of the limiting rack 22, pushing the sliding block 20 to slide along the fixing block 19, so that the limiting ring 21 at one end of the sliding block 20 fits against the edge of the film. After adjustment, release the pulling rod 25, and the reset spring 26 will push the limiting insert 24 into the limiting rack 22 for fixation, ensuring that films of different widths do not deviate during transport and meeting the transport path requirements of different types of films.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
