Abstract
Description
A lens positioning and mounting device Technical Field
[0001] This utility model relates to the field of lens processing technology, and more specifically, to a lens positioning and mounting device. Background Technology
[0002] In the manufacturing process of optical lenses, to meet complex imaging requirements, multiple lenses with different curvatures, materials, or coating properties are typically bonded together sequentially to form a composite optical system. To ensure that the optical performance meets design requirements, high-precision alignment and fixation must be achieved between the lenses. Therefore, optical lens positioning devices are widely used in the bonding process to ensure precise alignment of each lens layer during bonding, and pressure holding is used to fully cure the bonded layer, thereby obtaining a stable structure and high-quality optical performance.
[0003] In existing technologies, optical lens bonding is mostly performed using a layer-by-layer stacking method. Specifically, a reference lens is first fixed to a positioning device, and then other lenses are bonded sequentially to one side of it. However, when it is necessary to bond different types or shapes of lenses to both sides of the same lens, it is usually necessary to remove the lens that has been bonded on one side from the positioning device, flip it over, and re-clamp it to perform the bonding operation on the other side. This process not only increases manual operation steps but also has the following problems: 1. The disassembly and repositioning process prolongs processing time and reduces production efficiency. 2. Bonding stability risk: Repeated operation may introduce external contamination or stress changes, affecting the quality of the bonding interface and thus reducing the reliability of the lens. Summary of the Invention
[0004] The purpose of this invention is to provide a lens positioning and mounting device that can achieve efficient bonding of both lenses without disassembling the lens, thereby improving the assembly efficiency and quality of optical lenses.
[0005] This utility model is achieved through the following technical solution:
[0006] A lens positioning and installation device includes a working platform. The working platform has a rotating mechanism and a clamping mechanism on its surface. The rotating mechanism has a clamping assembly on its working surface. The rotating mechanism has symmetrical clamping platforms on both sides. The clamping mechanism is located above the clamping platforms and is opposite to the clamping platforms. The lower surface of the clamping assembly can abut against the upper surface of the clamping platform.
[0007] Furthermore, the rotating mechanism includes a fixed seat, a sliding seat, a gear, a rack, and a telescopic cylinder. The fixed seats are installed on both sides of the working platform, and the two fixed seats are connected by the rotating shaft. A mounting seat is fixed to the outside of the rotating shaft. The clamping assembly is fixedly connected to the mounting seat. One end of the rotating shaft passes through the fixed seat and is connected to the gear. The sliding seat is located below the gear. The rack is slidably installed on the sliding seat and meshes with the gear. The telescopic cylinder is connected to the rack.
[0008] Furthermore, the sliding seat surface is provided with a sliding groove, the rack is slidably installed in the sliding groove, a sliding block is provided on the outside of the rack, and the driving end of the telescopic cylinder is fixedly connected to the sliding block.
[0009] Furthermore, the clamping assembly includes a clamping cylinder and clamping blocks. The driving end of the clamping cylinder is provided with two clamping blocks, and the clamping cylinder is used to drive the two clamping blocks to move closer or further apart from each other.
[0010] Furthermore, the opposing sides of the two clamping blocks are curved surfaces.
[0011] Furthermore, the inner wall of the clamping block is provided with a protective pad.
[0012] Furthermore, the clamping mechanism includes a hydraulic cylinder and a clamping block. The working platform surface is provided with a support frame. The hydraulic cylinder is installed on the top of the support frame, and the drive end of the hydraulic cylinder passes through the support frame and is fixedly connected to the clamping block.
[0013] Furthermore, both the pressing block and the pressing table have flexible pads on their surfaces.
[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:
[0015] The clamping assembly positions and secures the lens, while the rotating mechanism drives the clamping assembly to rotate, simultaneously rotating the lens and enabling lens flipping. This allows for efficient bonding of both lenses without disassembling them, accelerating the assembly efficiency of optical lenses. The pressing mechanism and pressing table work together to maintain pressure and shape both lenses separately, ensuring the bond layer fully cures and improving the stability of the optical lens. The contact between the clamping assembly and the pressing table ensures the lens remains horizontal during pressure maintenance, preventing lens tilt from affecting the shaping effect and improving the assembly quality of the optical lens.

[0026] Example 1
[0027] Referring to Figures 1-3, this embodiment provides a lens positioning and installation device, including a working platform 1. The working platform 1 has a rotating mechanism and a pressing mechanism on its surface. The working surface of the rotating mechanism has a clamping component. The rotating mechanism has symmetrical pressing platforms 2 on both sides. The pressing mechanism is located above the pressing platform 2 and is opposite to the pressing platform 2. The clamping component can abut against the pressing platform 2.
[0028] The clamping assembly positions and fixes the lens, while the rotating mechanism drives the clamping assembly to rotate, simultaneously rotating the lens and enabling lens flipping. This allows for efficient bonding of both lenses without disassembling them, accelerating the assembly efficiency of optical lenses. The pressing mechanism and pressing table 2 work together to hold pressure and shape both lenses separately, allowing the bonded layer to fully cure and improving the stability of the optical lens. The lower surface of the clamping assembly abuts against the upper surface of the pressing table 2, ensuring the lens is horizontal during pressure holding and shaping, preventing lens tilt from affecting the shaping effect and improving the assembly quality of the optical lens.
[0029] In a preferred embodiment, the rotating mechanism includes a fixed seat 3, a sliding seat 6, a gear 7, a rack 8, and a telescopic cylinder 9. The fixed seat 3 is installed on both sides of the working platform 1, and the two fixed seats 3 are connected by the rotating shaft 4. A mounting seat 5 is fixed to the outside of the rotating shaft 4, and the clamping assembly is fixedly connected to the mounting seat 5. One end of the rotating shaft 4 passes through the fixed seat 3 and is connected to the gear 7. The sliding seat 6 is located below the gear 7. The rack 8 is slidably installed on the sliding seat 6 and meshes with the gear 7. The telescopic cylinder 9 is connected to the rack 8.
[0030] In a preferred embodiment, the sliding seat 6 has a groove 10 on its surface, the rack 8 is slidably installed in the groove 10, and a sliding block 11 is provided on the outer side of the rack 8. The drive end of the telescopic cylinder 9 is fixedly connected to the sliding block 11. The lower part of the sliding block 11 is slidably installed in the groove 10, and the upper part of the sliding block 11 extends out of the sliding seat 6 and is fixedly connected to the drive end of the telescopic cylinder 9. In use, the telescopic cylinder 9 drives the sliding block 11 to move along the length of the sliding seat 6, thereby moving the rack 8. The movement of the rack 8 drives the gear 7 to rotate, synchronously driving the rotating shaft 4 to rotate, causing the mounting seat 5 fixed to the rotating shaft 4 to rotate. This causes the lens held by the clamping assembly to rotate, achieving lens flipping and the purpose of bonding the lenses on both sides.
[0031] In a preferred embodiment, the clamping assembly includes a clamping cylinder 12 and clamping blocks 13. The driving end of the clamping cylinder 12 is provided with two clamping blocks 13, which are used to drive the two clamping blocks 13 closer together or further apart. When the clamping assembly is in a horizontal state, the central axes of the two clamping blocks 13, the central axis of the pressure table 2, and the central axis of the pressure block 15 coincide, improving the lens pressure holding and shaping effect. The piston rod of the clamping cylinder 12 directly or indirectly drives the clamping blocks 13 to move through mechanical connecting parts (such as floating joints or hinges). When the clamping blocks 13 contact the workpiece surface, the thrust of the clamping cylinder 12 continues to act, converting into a clamping force perpendicular to the lens surface, pressing the lens firmly onto the positioning reference surface.
[0032] As a preferred embodiment, the opposing side of the two clamping blocks 13 is an arc surface, which makes the clamping blocks 13 fit the outer peripheral surface of the lens better and improves the positioning and fixing effect of the lens.
[0033] In a preferred embodiment, the inner wall of the clamping block 13 is provided with a protective pad. The protective pad can protect the outer peripheral surface of the lens and prevent damage. The protective pad and the flexible pad 16 can be made of rubber or other elastic and flexible materials.
[0034] In a preferred embodiment, the clamping mechanism includes a hydraulic cylinder 14 and a clamping block 15. A support frame 17 is provided on the surface of the working platform 1. The hydraulic cylinder 14 is mounted on the top of the support frame 17, and the drive end of the hydraulic cylinder 14 passes through the support frame 17 and is fixedly connected to the clamping block 15. After the clamping block 13 positions and fixes the lens, the hydraulic cylinder 14 drives the clamping block 15 to descend until the clamping block 15 presses firmly against the lens surface. After maintaining pressure for a certain period, the lens adhesive layer is cured and shaped.
[0035] In a preferred embodiment, both the pressing block 15 and the pressing table 2 have flexible pads 16 on their surfaces. The flexible pads 16 can act as a buffer, reducing the rigid pressure on the lens surface and improving the safety of lens pressure molding.
[0036] The working principle of a lens positioning and mounting device is as follows: A lens is placed on the surface of a clamping table 2. A clamping cylinder 12 moves a clamping block 13 to position and fix the lens. Another lens is then bonded to the surface of this lens. A hydraulic cylinder 14 moves a clamping block 15 to maintain pressure and shape the lens. Then, a telescopic cylinder 9 moves a sliding block 11, which in turn moves a rack 8. The rack 8 moves a gear 7, which in turn rotates a rotating shaft 4, causing the mounting base 5 fixed to the rotating shaft 4 to rotate. This causes the lens held by the clamping block 13 to rotate until its lower surface abuts against the upper surface of another clamping table 2. Another lens is then bonded to the surface of this lens. The hydraulic cylinder 14 moves a clamping block 15, which again maintains pressure and shapes the lens, achieving efficient bonding of both lenses.
[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
