Description

Technical Field

[0001] This invention relates to the field of lens coating technology, specifically to an automatic double-sided ultra-hard AR optical coating device for camera lenses. Background Technology

[0002] AR coating reduces reflected light and increases transmitted light, thereby improving clarity. Coating one side can increase transmittance by 2% to 3%, while double-sided coating can increase transmittance by 4% to 6%. Camera cover glass has high transmittance requirements, so double-sided ultra-hard AR coating is usually required.

[0003] A search revealed a Chinese patent with application number "CN202320519352.2", which specifically describes a lens coating fixture. The fixture includes a transmission support assembly, a rotating assembly, and a limiting assembly. The transmission support assembly, while limiting the suspended positions of the rotating assembly and the limiting assembly within the coating cavity, is connected to the limiting assembly via the rotating assembly. The rotating inner rod of the rotating assembly is detachably inserted into a transmission connector that penetrates the support housing of the transmission support assembly. The rotating assembly is positioned and supported on the upper surface of the support housing via a support outer tube sleeved on the rotating inner rod. Multiple rotating housings are spaced apart on the support outer tube. Each rotating housing contains a transmission gear capable of being connected to the rotating inner rod. The output end of the transmission gear, away from the rotating inner rod, penetrates the side wall of the rotating housing and is connected to the limiting assembly.

[0004] In the aforementioned patent, the device controls the rotation of the lens to facilitate coating operations on multiple surfaces of the lens. However, when manually loading lenses, fibers and dander brought in by gloves, clothing, or tools increase the accumulation of dust and impurities on the lens surface. In addition, the number of lenses coated at one time is large, which increases the workload of the staff in cleaning the lenses. Furthermore, since multiple lenses are placed vertically, it is not convenient to disassemble and clean them individually. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides the following technical solutions:

[0029] Example 1

[0030] Please see Figure 1 - Figure 5An automatic double-sided ultra-hard AR optical coating device for camera lenses includes a coating machine body 1, a support block 2 fixedly connected to the lower side of the coating machine body 1, a rotating shaft 4 rotatably connected to the inner side of the coating machine body 1, a turntable 5 fixedly connected to the upper side of the rotating shaft 4, a motor 3 for driving the rotating shaft 4 to rotate fixedly connected to the lower side of the coating machine body 1, an installation unit 6 provided on the upper side of the turntable 5, the installation unit 6 including multiple rotating tubes 64, all of which are rotatably connected to the lower side of the turntable 5, the upper end of the rotating tubes 64 passing through the upper side of the turntable 5 and fixedly connected to a control disk 65, an installation component 66 provided on the upper side of the control disk 65, the installation component 66 being used for cleaning after lens coating is completed, when coating camera lenses, the lens is placed on the installation unit 6, and the coating operation is completed by the vacuum coating component inside the coating machine body 1.

[0031] Gear 67 is fixedly connected to the lower end of the rotating tube 64. The mounting assembly 66 includes multiple rotating rods 661, all rotatably connected to the upper side of the control panel 65. Gear 663 is fixedly connected to the upper end of each rotating rod 661. Gear 662 is fixedly connected to the lower end of each rotating rod 661, passing under the turntable 5 and located below the rotating tube 64. A vertical rod 61 is fixedly connected to the inner side of the coating machine body 1. A gear ring 62, meshing with gear 662, is fixedly connected to the outer side of the vertical rod 61. A gear ring 63, meshing with gear 67, is fixedly connected to the upper end of the vertical rod 61. The upper part of the control panel 65... Multiple side blocks 664 are fixedly connected to the side. A rotating block 665 is rotatably connected to the outer side of the side block 664. A rotating plate 666 is fixedly connected to the upper side of the rotating block 665. A mounting rod 6613 is rotatably connected to the upper side of the rotating plate 666. A mounting plate 6614 is fixedly connected to the upper end of the mounting rod 6613. Multiple placement holes 6617 are opened on the outer side of the mounting plate 6614. A lens body 6618 is provided on the inner side of the placement hole 6617. A mounting rod 6615 is fixedly connected to the upper side of the mounting plate 6614. A gear 6616 that meshes with a gear 663 is fixedly connected to the upper end of the mounting rod 6615.

[0032] During the coating process, the lens body 6618 is first installed on the placement hole 6617. Then, the motor 3 is started, which drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the turntable 5 to rotate, and the turntable 5 drives the control disk 65 on the rotating tube 64 to revolve. The rotating tube 64 drives the gear 67 to rotate along the trajectory of the gear ring 63. Since the gear 67 is meshed with the gear ring 63, the gear 67 rotates, which drives the rotating tube 64 to rotate. The rotating tube 64 drives the control disk 65 to rotate, and the control disk 65 drives the lens body 6618 on the mounting plate 6614 to revolve along the direction of the control disk 65. At the same time, the control disk 65 drives the gear on the rotating rod 661 to revolve. Gear 2 662 rotates along the trajectory of gear ring 1 62. Since gear 2 662 is meshed with gear ring 1 62, gear 2 662 rotates on its own. Gear 2 662 drives rotating rod 1 661 to rotate. Rotating rod 1 661 drives gear 3 663 to rotate. Gear 3 663 drives gear 4 6616 to rotate. Gear 4 6616 drives mounting rod 2 6615 to rotate. Mounting rod 2 6615 drives mounting plate 6614 to rotate. Mounting plate 6614 drives lens body 6618 to flip, which facilitates multi-faceted uniform coating on lens body 6618. The coated AR anti-reflective coating is an ultra-hard coating. After coating, it can be cleaned by soft brush roller 6632.

[0033] Multiple adjustment holes 6619 are provided on the outer side of the mounting plate 6614. Two adjustment sliders 6620 are slidably connected to the outer side of the adjustment holes 6619. A spring piece 6621 is fixedly connected between the two adjustment sliders 6620. Bolts are provided between the adjustment sliders 6620 and the mounting plate 6614. The spring piece 6621 has an arc-shaped structure. The adjustment sliders 6620 are provided to facilitate the adjustment of the bending degree of the spring piece 6621, so that multiple spring pieces 6621 can clamp and limit the lens body 6618 of various models.

[0034] Two upright plates 667 are fixedly connected to the upper side of the rotating plate 666. A top plate 668 is fixedly connected to the upper side of the upright plate 667. Mounting rod 6615 is rotatably connected to the top plate 668. Inclined plates 669 are rotatably connected to the outer sides of the two upright plates 667. A connecting block 6610 is rotatably connected to the outer side of the lower end of the inclined plate 669. A lifting ring 6611 is fixedly connected to the lower side of the connecting block 6610. An electric push rod 6612 is fixedly connected between the lifting ring 6611 and the control panel 65. After the coating is completed, the electric push rod 6612 is controlled to drive the lifting ring 6611 to rise. The lifting ring 6611 drives the inclined plate 669 to rotate. Since the two inclined plates 669 are symmetrically distributed, the inclined plates 669 drive the upright plates 667 to rotate and tilt. The upright plates 667 drive the rotating plate 666 to rotate. The rotating plate 666 drives the mounting plate 6614 to rotate, so that the lens body 6618 on the mounting plate 6614 changes from an upright state to a horizontal position, which is convenient for subsequent cleaning.

[0035] Example 2

[0036] Based on Example 1, such as Figure 6 - Figure 9 As shown, two guide plates 6629 are fixedly connected to the side of each of the two upright plates 667 near the mounting plate 6614. Guide blocks 6630 are slidably connected to the outer side of each guide plate 6629. A connecting rod 6631 is rotatably connected between the left and right guide blocks 6630. A soft brush roller 6632 is fixedly connected to the outer side of the connecting rod 6631. A control block 6635 is fixedly connected between the two guide blocks 6630 on the same side. A rectangular hole 6622 is opened on the lower side of the rotating plate 666. A base block 6623 is fixedly connected to the lower side of the rotating plate 666. A second rotating rod 6625 is rotatably connected to the outer side of the base block 6623. A take-up roller 6624 is fixedly connected to the outside. An elastic rope 6628 is wound around the outside of the take-up roller 6624. The elastic rope 6628 passes through the rectangular hole 6622 through the upper side of the turn plate 666 and is fixedly connected to the control block 6635. A gear 6626 is fixedly connected to the outer end of the second rotating rod 6625. A toothed plate 6627 that meshes with the gear 6626 is fixedly connected to the upper side of the control panel 65. The toothed plate 6627 has an arc-shaped structure. A gear 6633 is fixedly connected to the outside of the connecting rod 6631. A toothed plate 6634 that meshes with the gear 6633 is fixedly connected to the upper side of the turn plate 666.

[0037] When the upright plate 667 rotates and tilts, the upright plate 667 drives the gear 6626 at the bottom of the rotating plate 666 to rotate. Since the gear 6626 meshes with the gear plate 6627, the gear 6626 rotates, which in turn drives the rotating rod 6625 to rotate. The rotating rod 6625 drives the take-up roller 6624 to rotate, which in turn drives the tension rope 6628 to take up. The tension rope 6628 pulls up the guide block 6630 and lowers it. The guide block 6630 drives the flexible rod 6631 to move. As the brush roller 6632 descends, the connecting rod 6631 simultaneously drives the gear 6633 to descend. Since the gear 6633 meshes with the toothed plate 6634, it rotates, causing the soft brush roller 6632 on the connecting rod 6631 to rotate. This facilitates the cleaning of dust and impurities from the surface of the lens body 6618 by the soft brush rollers 6632 on both sides. The soft brush rollers 6632 on both sides allow for simultaneous cleaning of both sides of the lens body 6618, making the operation simple.

[0038] Working principle: During use, the operator first places the lens body 6618 in the placement hole 6617 and limits the lens body 6618 by the spring piece 6621. During coating, the motor 3 is started, and the motor 3 drives the turntable 5 on the rotating shaft 4 to rotate. The turntable 5 drives the control disk 65 to revolve. At the same time, under the action of the rotating tube 64, gear 1 67, and gear ring 2 63, the control disk 65 rotates, and the control disk 65 drives the lens body 6618 to rotate. At the same time, under the action of the rotating rod 1 661, gear 2 662, and gear ring 1 62, the gear 3 663 is controlled to rotate. Under the action of the gear 4 6616 and the mounting rod 2 6615, the lens body 6618 on the mounting plate 6614 is controlled to flip, which facilitates the double-sided coating operation of the lens body 6618. After the coating is completed, the electric push rod 6612 is controlled to drive the lifting ring 6611 to rise. The lifting ring 6611 drives the inclined plate 669 to rotate. The inclined plates 669 are symmetrically distributed, facilitating the rotation and tilting of the upright plate 667. The upright plate 667 drives the lens body 6618 from an upright position to a horizontal position, facilitating subsequent material handling and cleaning. Simultaneously, the upright plate 667 drives the rotating plate 666 to rotate, which in turn drives gear five 6626 to rotate along gear plate one 6627. Since gear five 6626 is meshed with gear plate one 6627, the rotation of gear five 6626... The take-up roller 6624 on the rotating rod 6625 rotates, causing the control block 6635 to descend under the action of the tension rope 6628. The control block 6635 drives the guide block 6630 to descend, and the guide block 6630 drives the soft brush roller 6632 on the connecting rod 6631 to descend. At the same time, under the action of the gear 6633 and the toothed plate 6634, the soft brush rollers 6632 on both sides are controlled to rotate, which facilitates the cleaning of dust and impurities on both sides of the lens body 6618.
