Description

Technical Field

[0001] This utility model relates to the field of optical lens coating technology, specifically to an optical lens rotary coating device. Background Technology

[0002] In the field of optical device manufacturing, lens surface coating is a key process for improving optical performance. Traditional coating methods typically include the following steps: first, the optical lens is cleaned in a cleaning tank, then dried, and finally fixed in a fixture before being fed into a coating machine for single-sided coating. However, this process has a significant drawback: during single-sided coating, the uncoated surface is exposed to the environment and is susceptible to chemical vapor contamination, affecting the coating on that surface and thus reducing the yield of the finished product.

[0003] Patent document CN 220846244 U includes a housing. A first limiting rod is vertically fixed to the middle of the left side of the bottom interior of the housing, and a first screw is vertically rotatably connected to the middle of the right side of the bottom interior of the housing. In this invention, the position of the clamping assembly can be adjusted by the first servo motor, the first screw, and the first limiting rod. Raising the clamping assembly facilitates lens clamping, with the lens placed within the opening. A limiting ring limits the rear side of the lens. The spacing between the arc-shaped clamping plates can be adjusted by the second servo motor, the bidirectional screw, and the second limiting rod. The arc-shaped clamping plates limit the front side of the lens. Inflating the annular airbag seals the side of the lens. After the clamping assembly lowers, the sealing plate seals the groove of the end cap, and the sealing gasket engages with the sealing groove for a seal.

[0004] Although the aforementioned patent achieves sealed separation of the housing through the cooperation of structures such as clamping components, coating equipment, sealing gaskets, sealing grooves, and sealing plates, ensuring that the other side of the optical lens is not contaminated during coating, this solution still has the following limitations: because the device can only clamp a single lens at a time when coating the optical lens, the overall coating efficiency is low and cannot meet the needs of industrial mass production.

[0031] Example 1

[0032] To address the technical problems in the background art, the following optical lens rotation coating device is provided:

[0033] Combination Figures 1-8 As shown, the optical lens rotary coating device provided by this utility model includes a coating box 1; the bottom surface of the inner cavity of the coating box 1 is provided with sliding grooves 2, a movable frame assembly 3 is slidably connected in the sliding grooves 2, an auxiliary coating assembly 4 is installed in the middle of the movable frame assembly 3, a U-shaped rod 5 is fixedly connected to the upper part of the inner wall of the coating box 1, and parallel rails 6 are fixedly connected to both sides of the inner wall of the U-shaped rod 5. The two sides of the movable frame assembly 3 slide on the surface of the parallel rails 6, and the inner wall of the coating box 1 is located on the U-shaped rod. The first nozzle 7 and the second nozzle 8 are fixedly connected to both sides of the coating box 1, and a sealing component 9 is installed on one side of the coating box 1. The moving frame component 3 includes a sliding rod 31, which is slidably connected in the sliding groove 2. A base plate 32 is fixedly connected to the top surface of the sliding rod 31. A vertical pole 33 is fixedly connected to one end of the top surface of the base plate 32. A placement plate 34 is fixedly connected to the top surface of the vertical pole 33. A stepped placement groove 35 is provided in the middle of the placement plate 34. The two ends of the placement plate 34 slide on the surface of the parallel rail 6.

[0034] By using the placement plate 34 in conjunction with the clamping component 45, the coating box 1 can be divided into two chambers, so that both chambers are in a relatively sealed state. This facilitates the later spraying of different liquid films from the first nozzle 7 and the second nozzle 8, so as to achieve coating different films on both sides of the optical lens, or coating only one side.

[0035] In this embodiment, the auxiliary coating assembly 4 includes a drive motor 41. The drive motor 41 is fixedly connected to the top surface of the base plate 32. A column rod 42 is fixedly connected to the output shaft end of the drive motor 41. An auxiliary support component 43 is installed on the surface of the column rod 42. A spline hole 44 is provided on the top surface of the column rod 42. A clamping component 45 is connected to the top surface of the column rod 42 through the spline hole 44. The clamping component 45 is placed in the stepped placement groove 35.

[0036] The drive motor 41 drives the clamping component 45 to rotate, thereby causing the clamped optical lens to rotate, which facilitates the first spray head 7 and the second spray head 8 to spray coating on both sides of the optical lens.

[0037] Example 2

[0038] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0039] The auxiliary support component 43 includes a threaded sleeve 431, which is slidably connected to the surface of the column rod 42. The threaded sleeve 431 has symmetrically arranged lifting grooves 432 on its surface. A threaded screw 433 is threadedly connected to the surface of the threaded sleeve 431. A bracket 434 is rotatably connected to the top surface of the threaded screw 433. The bracket 434 is mounted on the surface of the threaded sleeve 431 and slides within the lifting grooves 432. A tray 435 is fixedly connected to the top surface of the bracket 434. The auxiliary support component 43 also includes an auxiliary plate 436 and a rectangular block 437. The rectangular block 437 is fixedly connected to the bottom surface of the threaded sleeve 431 and slides on the surface of the column rod 42. Cylindrical rods 438 are fixedly connected to both sides of the rectangular block 437. The auxiliary plate 436 is fixedly connected to both sides of the inner wall of the coating chamber 1. A inclined groove 439 is provided on one side of the auxiliary plate 436, and the cylindrical rods 438 slide within the inclined groove 439.

[0040] The optical lens inside the placement hole 452 can be lifted by the bracket 434 and tray 435 in the auxiliary support component 43, which facilitates clamping later.

[0041] By cooperating with the threaded sleeve 431 and the threaded screw 433 in the auxiliary support component 43, the height of the bracket 434 and the tray 435 can be adjusted, thereby adjusting the height of the tray 435 in the placement hole 452, which is convenient for supporting optical lenses of different thicknesses in the later stage and facilitating the later positioning and clamping.

[0042] Through the cooperation of the inclined groove 439 and the cylindrical rod 438, when it is necessary to place the optical lens, the tray 435 is positioned below the optical lens, which facilitates the subsequent lifting of the optical lens. When it is necessary to perform coating, the tray 435 needs to be moved away from the bottom of the optical lens to avoid affecting the subsequent coating.

[0043] Example 3

[0044] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0045] The clamping component 45 includes a storage tray 451, which is placed in a stepped placement groove 35. The top surface of the storage tray 451 has a circumferential array of placement holes 452. A clamping cavity 453 is provided in the middle of the inner cavity of the storage tray 451. The clamping cavity 453 communicates with the placement holes 452. A clamping rod 454 is slidably connected in the clamping cavity 453. A reset damping rod 455 is fixedly connected to one side of the clamping rod 454 and between the inner wall of the clamping cavity 453. A pressing threaded rod 456 is threadedly connected to the storage tray 451. A truncated cone 457 is rotatably connected to one end of the pressing threaded rod 456. The surface of the truncated cone 457 is in contact with one end of the clamping rod 454. A guide rod 458 is fixedly connected to the top surface of the truncated cone 457. A splined rod 459 is fixedly connected to the middle of the bottom surface of the storage tray 451. The splined rod 459 is inserted into the splined hole 44.

[0046] The downward threaded rod 456 in the clamping component 45 drives the cone 457 to move downward, thereby causing the cone 457 to press the clamping rod 454, and the optical lens in the placement hole 452 can be clamped and fixed through the other end of the clamping rod 454.

[0047] Since the clamping component 45 is placed in the stepped placement slot 35 and the clamping component 45 is connected to the drive motor 41 by the spline rod 459, it is convenient for the staff to remove and place the clamping component 45 later.

[0048] In this embodiment, the sealing assembly 9 includes a fixing block 91. The fixing block 91 is fixedly connected to one end of the top surface of the coating box 1. A bidirectional pneumatic rod 92 is fixedly connected inside the fixing block 91. A sealing door 93 is fixedly connected to the output end of the bidirectional pneumatic rod 92.

[0049] The two sets of sealing doors 93 are moved in opposite directions by the bidirectional pneumatic rod 92 in the sealing assembly 9, thereby sealing the coating box 1 and facilitating the subsequent coating process. When the coating box 1 is opened, it will be convenient to place or remove the optical lens later.

[0050] Working principle and usage process of this utility model:

[0051] In use:

[0052] In use, first, start the bidirectional pneumatic rod 92. When the bidirectional pneumatic rod 92 is working, it will drive the two sets of sealing doors 93 to move to both sides, thereby opening the coating box 1.

[0053] After opening the coating box 1, the operator pulls the base plate 31. As the base plate 31 moves, it causes the sliding rod 31 to slide within the sliding groove 2. This movement also moves the placement plate 34 via the upright rod 33, causing it to slide within the parallel rail 6. The movement of the base plate 31 and placement plate 34 drives the drive motor 41 and the column rod 42. The movement of the column rod 42 moves the threaded sleeve 431, bracket 434, tray 435, and rectangular block 437. The movement of the rectangular block 437 moves the cylindrical rod 438 within the inclined groove 439. The movement of the cylindrical rod 438 then moves the rectangular block 437, tray 435, bracket 434, and threaded sleeve 431 along... Moving upward along the inclined groove, when the placement plate 34 and the base plate 32 are completely pulled out of the coating box 1, the pulling stops, and the operator places the clamping component 45 into the stepped placement groove 35. During placement, it is also necessary to ensure that the spline rod 459 is properly engaged with the spline hole 44, and that the tray 435 is located within the placement hole 452. After the clamping component 45 is placed stably, the operator begins to place the optical lens that needs to be coated. During placement, the operator first adjusts the height of the tray 435 within the placement hole 452 according to the thickness of the optical lens. During adjustment, the operator rotates the threaded screw 433. When the threaded screw 433 rotates, the bracket 434 slides along the lifting groove 432. As the bracket 434 moves, the height of the tray 435 is adjusted.

[0054] After adjustment, the operator places the optical lens requiring coating into the placement hole 452. The optical lens 452 is then positioned on the tray 435. Once all optical lenses are in place, the operator rotates the downward-pressing threaded rod 456. This rotation causes the truncated cone 457 to move downwards, pressing one end of the clamping rod 454. The clamping rod 454 then moves and stretches the reset damping rod 455. Simultaneously, the clamping rod 454, under the action of the placement hole 452, clamps the optical lens. After clamping, the operator can then push the base plate 3. 2. The entire auxiliary coating assembly 4 can be moved into the coating box 1. At the same time, the auxiliary support component 43 will move the tray 435 away from the optical lens under the action of the inclined groove 439. At this time, the two sides of the optical lens are facing the first nozzle 7 and the second nozzle 8 respectively. Then, the drive motor 41 is started. When the drive motor 41 is working, it will drive the column rod 42 and the clamping component 45 to rotate, thereby moving the optical lens to the two sets of first nozzles 7 and second nozzles 8. At this time, the coating material can be transported into the first nozzles 7 and the second nozzles 8 through external equipment and sprayed out. After spraying out, the coating of the optical lens begins.
