Description

Technical Field

[0001] This utility model relates to the field of resin lens vacuum coating technology, and in particular to a resin lens flipping mechanism for a vacuum coating machine. Background Technology

[0002] Vacuum coating machines mainly refer to a type of coating that needs to be carried out under high vacuum conditions. They include many types, such as vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, and many others.

[0003] The main functions of vacuum coating on resin lenses include increasing hardness, reducing reflection, enhancing abrasion resistance, improving transparency, providing UV protection, preventing static electricity, and preventing staining. During the vacuum coating process, a flipping mechanism is typically used within the coating chamber to rotate multiple resin lenses unidirectionally along the inner wall of the chamber to ensure a more uniform coating. However, since resin lenses require double-sided coating, simply rotating them unidirectionally cannot guarantee the overall coating effect. Utility Model Content

[0004] This utility model discloses a resin lens flipping mechanism for a vacuum coating machine, which aims to solve the technical problem that since resin lenses require double-sided coating, simply rotating them in one direction cannot guarantee the overall coating effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A resin lens flipping mechanism for a vacuum coating machine includes a vacuum coating chamber, a motor disposed on the inner wall of the top of the vacuum coating chamber, a first rotary drive seat fixedly connected to the output end of the motor, drive sub-seats connected to multiple output ends of the first rotary drive seat, a rotating rod connected to one end of the drive sub-seats, a limiting mechanism connected between the rotating rod and the drive sub-seats, multiple second rotary drive seats equidistantly disposed within the rotating rod, a support rod snapped onto the second rotary drive seats, multiple metal spring clips fixedly connected to the support rods, and a linkage mechanism simultaneously connecting the multiple support rods.

[0007] The multiple metal elastic clips are divided into two groups, and the two groups of metal elastic clips are arranged symmetrically. Multiple L-shaped brackets are fixedly connected at equal intervals on the outer wall of the first rotary drive seat, and a limit sleeve is fixedly connected to the bottom end of each L-shaped bracket.

[0008] By incorporating a first rotary drive seat, a second rotary drive seat, and a motor, the entire flipping structure is driven by the motor to rotate around the motor output end as the axis. Through the drive of the first rotary drive seat and the internal structure of multiple drive seats, each rotating rod can be driven to rotate around the central axis of the drive seat via a limiting mechanism. On each rotating rod, each second rotary drive seat can drive each support rod to rotate. This allows multiple resin lenses to rotate in different directions from a large range to a small range, which can better ensure the uniformity of coating on multiple resin lenses during vacuum coating.

[0009] In a preferred embodiment, the limiting mechanism includes an extension rod fixedly connected to one end of the rotating rod, a limiting support rod movably sleeved outside the extension rod, a support sleeve fixedly connected to one end of the limiting support rod, and a limiting insert rod inserted into the extension rod.

[0010] The limiting sleeve is movably sleeved on the outside of the limiting support rod, and the outer walls of the opposite sides of the extension rod are respectively fixedly connected with side protrusions, and a limiting through hole is provided through one side of the extension rod.

[0011] The limiting rod is movably inserted through the limiting hole, and the two ends of the limiting support rod are provided with through slots, and the extension rod and the side protrusion pass through the through slots at the same time.

[0012] The limiting rod is located inside the support sleeve, and one end of the limiting rod is movably connected to a handle, while one end of the limiting rod is fixedly connected to a snap-fit ​​connector.

[0013] One side of the support sleeve is fixedly connected to a limiting block, and the inner wall of one side of the limiting block is provided with an outer through groove and an inner locking groove. The inner locking groove is located inside the outer through groove, and the locking head passes through the outer through groove and is locked in the inner locking groove.

[0014] By setting a limiting mechanism, when installing the rotating rod, the extension rod and the side protrusion can be passed through the through slot, and then the limiting rod can be inserted into the limiting through hole to complete the limiting installation of the entire rotating rod. In addition, by rotating and pushing the limiting rod forward, the snap-fit ​​connector can pass through the outer through slot and be placed horizontally in the inner snap-fit ​​slot. The position of the limiting rod can be fixed by the limiting of the inner snap-fit ​​slot. With this structure, the disassembly and installation of the rotating rod are simpler, and the stability after installation is also guaranteed.

[0015] In a preferred embodiment, the linkage mechanism includes a limiting ring, a first clamping plate, a second clamping plate connected to the first clamping plate via a hinge, and magnetic suction plates respectively fixed to one end of the first clamping plate and the second clamping plate.

[0016] The limiting rings are respectively fixed to the outer walls of multiple support rods, and the first clamping plate and the second clamping plate are simultaneously clamped outside the limiting rings of multiple support rods;

[0017] The first clamping plate and the second clamping plate are respectively provided with clamping grooves on opposite sides, and the limiting ring is engaged in the clamping grooves, and the two magnetic plates attract each other.

[0018] With the linkage mechanism in place, the limiting rod can be removed after the resin lens vacuum coating is completed, so that the entire support rod structure can be detached. After detachment, it can be clamped onto multiple limiting rings in the same row by the first clamp and the second clamp. Thus, when disassembling the support rod, the first clamp and the second clamp can be used as a linkage and can also serve as a bottom support, making it convenient to place multiple horizontal support rods to store the resin lens on each metal elastic clip.

[0019] As described above, a resin lens flipping mechanism for a vacuum coating machine includes a vacuum coating chamber, a motor disposed on the inner wall of the top of the vacuum coating chamber, a first rotary drive seat fixedly connected to the output end of the motor, drive sub-seats connected to multiple output ends of the first rotary drive seat, a rotating rod connected to one end of the drive sub-seats, a limiting mechanism connecting the rotating rod and the drive sub-seats, multiple second rotary drive seats equidistantly disposed within the rotating rod, a support rod snapped onto the second rotary drive seats, multiple metal spring clips fixedly connected to the support rods, and a linkage mechanism connecting the multiple support rods. The resin lens flipping mechanism for the vacuum coating machine provided by this utility model has the technical effect of driving multiple resin lenses to rotate in different directions from a large range to a small range, thus better ensuring the uniformity of coating on multiple resin lenses during the vacuum coating process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] The resin lens flipping mechanism of the vacuum coating machine disclosed in this utility model is mainly used in the scenario of vacuum coating of resin lenses.

In structure 3, the entire flipping structure is driven by motor 5 to rotate around the output end of motor 5. Through the drive of the internal structure of the first rotating bracket 9 and multiple drive seats 10, each rotating rod 2 can be driven to rotate around the central axis of the drive seat 10 via the limiting mechanism 4. On each rotating rod 2, each support rod 11 can be driven to rotate via each second rotating drive seat 12. Thus, after the resin lens is clamped by the metal elastic clamp 7, multiple resin lenses can be driven to rotate in different directions from a large range to a small range. During the vacuum coating process, the uniformity of coating of multiple resin lenses can be better guaranteed.

[0031] Reference Figure 4 In a preferred embodiment, the limiting sleeve 8 is movably sleeved on the limiting support rod 408, and the outer walls of the opposite sides of the extension rod 401 are respectively fixedly connected with side protrusions 402, and a limiting through hole 403 is provided through one side of the extension rod 401.

[0032] Reference Figure 4 In a preferred embodiment, the limiting rod 406 is movably inserted through the limiting hole 403, and the two ends of the limiting support rod 408 are provided with through grooves 409, and the extension rod 401 and the side protrusion 402 pass through the through grooves 409 at the same time.

[0033] Reference Figure 5 In a preferred embodiment, the limiting rod 406 is partially located inside the support sleeve 405, and one end of the limiting rod 406 is movably connected to a handle 407, while one end of the limiting rod 406 is fixedly connected to a snap connector 410.

[0034] Reference Figure 5 In a preferred embodiment, a limiting block 404 is fixedly connected to one side of the support sleeve 405, and an outer through groove 411 and an inner locking groove 412 are provided on the inner wall of one side of the limiting block 404. The inner locking groove 412 is located inside the outer through groove 411, and the locking connector 410 passes through the outer through groove 411 and is locked into the inner locking groove 412. In the limiting mechanism 4, when the rotating rod 2 is installed, the extension rod 401 and the side protrusion 402 can pass through the through groove 409. The side protrusion 402 is used to achieve the desired effect. The synchronous rotation of the limiting support rod 408 and the rotating rod 2 allows the limiting insert rod 406 to be inserted into the limiting through hole 403, completing the limiting installation of the entire rotating rod 2. In addition, by rotating and pushing the limiting insert rod 406 forward, the clamping connector 410 can pass through the outer through groove 411 and be placed horizontally in the inner clamping groove 412. The limiting position of the limiting insert rod 406 can be fixed by the limiting of the inner clamping groove 412. With this structure, the disassembly and installation of the rotating rod 2 are simpler, and the stability after installation is also guaranteed.

[0035] Reference Figure 3In a preferred embodiment, the linkage mechanism 3 includes a limiting ring 305, a first clamping plate 301, a second clamping plate 304 connected to the first clamping plate 301 via a hinge, and magnetic suction plates 303 respectively fixed to one end of the first clamping plate 301 and the second clamping plate 304.

The two magnetic suction plates 303 attract each other. After the resin lens vacuum coating is completed, the limiting rod 406 can be removed, so that the entire structure of the support rod 11 can be detached. After detachment, the first clamping plate 301 and the second clamping plate 304 can be engaged on multiple limiting rings 305 in the same row, and the magnetic suction plates 303 can attract one end of the first clamping plate 301 and the second clamping plate 304 to fit together. Thus, when disassembling the support rod 11, the first clamping plate 301 and the second clamping plate 304 can be used as a linkage and as a bottom support, which makes it convenient to place multiple support rods 11 horizontally to store the resin lens on each metal elastic clip 7.

[0038] Working principle: In the entire flipping structure, the motor 5 can drive the whole to rotate around the output end of the motor 5. Through the drive of the internal structure of the first rotating bracket 9 and multiple drive seats 10, the limiting mechanism 4 can drive each rotating rod 2 to rotate around the central axis of the drive seat 10. On each rotating rod 2, each second rotating drive seat 12 can drive each support rod 11 to rotate. Thus, after the resin lens is clamped by the metal elastic clamp 7, multiple resin lenses can be driven to rotate in different directions from a large range to a small range. During the vacuum coating process, the uniformity of the coating of multiple resin lenses can be better guaranteed.
