Description

Technical Field

[0001] This utility model relates to the field of coated umbrella technology, specifically to a coated umbrella that can improve color difference edges. Background Technology

[0002] Optical coating is a common technique for improving the surface performance of optical devices. To increase the light transmittance of a lens or its reflectivity to certain wavelengths of light, a corresponding film is deposited on the lens surface; this results in a coated lens. In the vacuum coating process, the lens is typically placed on a coating umbrella, which is then placed in a vacuum environment for coating. However, conventional coating umbrellas use an edge-overlapping or corner-overlapping opening design, meaning the lens is positioned by overlapping edges or contacting corners. The defects of this process are as follows: 1) When the film thickness exceeds 4000nm, the internal stress of the film is too large, causing microscopic warping deformation of 0.1-0.3mm at the lens edge; 2) The lap welding rod is prone to thermal fatigue in the continuous high temperature (150-200℃) coating environment, and deformation displacement occurs after multiple use cycles; 3) Due to the difference in film thickness between the coating area and the normal coating area, visible chromatic aberration edges are formed under optical interference (commonly manifested as purple edges or rainbow patterns); 4) Because the lens is directly fitted into the orifice on the coating umbrella, it is not convenient to clamp the coated lens out of the orifice after coating, and there is no fixed limiting structure between the lens and the orifice, so the lens may fall off when the coating umbrella is rotated. Therefore, a coating umbrella that can improve the chromatic aberration edge is provided to solve the above problems. Utility Model Content

[0003] To solve the problems mentioned above, the technical solution adopted by this utility model is: a coated umbrella that can improve color difference edges, comprising: an umbrella tray, the umbrella tray having a lens opening, the inner edge of the lens opening having a stepped groove, the corner of the lens opening having an arc-shaped opening on one side of the stepped groove, the top of the lens opening having symmetrical notches on both sides, the notches having limiting insertion ports, the limiting insertion ports having rectangular blocks that fit into each other, one end of the rectangular block having a locking block fixedly connected to it by a screw, the locking block having an L-shaped locking slot for locking the lens at one end of the lens opening, the upper and lower ends of the rectangular block having a first L-shaped locking rod and a second L-shaped locking rod that are slidably connected to each other, and one end of the rectangular block passing through the limiting insertion port and being limited by the first L-shaped locking rod and the second L-shaped locking rod.

[0004] As a preferred embodiment of this utility model, the limiting socket is a rectangular structure, and a limiting groove is formed between the first L-shaped locking rod and the second L-shaped locking rod on the rectangular block. A spring is provided inside the limiting groove between the first L-shaped locking rod and the second L-shaped locking rod.

[0005] As a preferred embodiment of this utility model, each of the first L-shaped locking rod and the second L-shaped locking rod is provided with a locking post on the opposite side, and the locking post is sleeved on the end of the spring.

[0006] As a preferred technical solution of this utility model, the locking block has a first limiting port at one end facing the first L-shaped locking rod, and the locking block has a second limiting port at one end facing the second L-shaped locking rod.

[0007] As a preferred technical solution of this utility model, the first L-shaped locking rod and the second L-shaped locking rod are distributed and slide through the first limiting port and the second limiting port, and the lens opening is located on one side of the stepped groove and the lens body is placed therein.

[0008] As a preferred technical solution of this utility model, the card block is connected to the outside of the lens body through one end of the L-shaped card slot, the top of the umbrella disk is provided with a reinforcing rib, and one side of the inside of the notch is on the same plane as the stepped groove.

[0009] The present invention has the following advantages: The present invention forms a stepped groove structure inside the lens opening in one step. The stepped groove step surface forms a surface contact support with the edge of the lens body, which can avoid the phenomenon of coating around the lens body caused by stress warping, reduce the formation of color difference edge after coating, and the one-piece molding technology overcomes the problem of easy deformation and fall-off of traditional edge welding rods, so that the lens remains stable during the coating process.

[0010] Furthermore, the notches on both sides of the lens opening not only facilitate the clamping of the lens body placed in the lens opening, but also allow the insertion of rectangular blocks through the limiting slots in the notches. The lens body is then clamped into the lens opening through the L-shaped latches on the end of the rectangular blocks, thus effectively preventing the lens body from falling off due to the rotation of the umbrella disc during coating.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Please refer to the following: Figures 1-5 This utility model discloses a coated umbrella that can improve color difference edges, comprising: an umbrella tray 1, an umbrella tray 1 having a lens opening 2, a stepped groove 3 on the inner edge of the lens opening 2, an arc-shaped opening 4 at the corner of the lens opening 2 located on one side of the stepped groove 3, symmetrical notches 5 on both sides of the top of the lens opening 2, a limiting insertion port 6 in the notch 5, a rectangular block 7 being inserted into the limiting insertion port 6, a locking block 8 being fixedly connected to one end of the rectangular block 7 by a screw, the locking block 8 having an L-shaped locking slot 9 for locking the lens at one end of the lens opening 2, a first L-shaped locking rod 11 and a second L-shaped locking rod 12 being slidably connected to the upper and lower ends of the rectangular block 7 respectively, and one end of the rectangular block 7 passing through the limiting insertion port 6 and being limited by the first L-shaped locking rod 11 and the second L-shaped locking rod 12.

[0021] The limiting socket 6 is rectangular. A limiting groove 10 is formed between the first L-shaped locking rod 11 and the second L-shaped locking rod 12 in the rectangular block 7. A spring 14 is provided inside the limiting groove 10 between the first L-shaped locking rod 11 and the second L-shaped locking rod 12. The elastic force of the spring 14 can ensure that the first L-shaped locking rod 11 and the second L-shaped locking rod 12 move away from each other. A locking post 13 is provided on the opposite side of the first L-shaped locking rod 11 and the second L-shaped locking rod 12. The locking post 13 is sleeved on the end of the spring 14. The locking post 13 can limit the spring 14. A first limiting port 15 is formed at the end of the locking block 8 facing the first L-shaped locking rod 11. A second limiting port 16 is formed at the end of the locking block 8 facing the second L-shaped locking rod 12.

[0022] The first L-shaped locking rod 11 and the second L-shaped locking rod 12 slide through the first limiting port 15 and the second limiting port 16, respectively. The lens body 17 is placed on one side of the stepped groove 3, with the lens opening 2 fitting snugly. The locking block 8 is engaged with the outer side of the lens body 17 through one end of the L-shaped locking slot 9. The top of the umbrella tray 1 is provided with a reinforcing rib 18 to ensure the stability of the umbrella tray 1 structure. One side of the notch 5 is on the same plane as the stepped groove 3. Based on the size of the lens body 17 and the requirements of the coating process, the fit tolerance range between the coating umbrella opening and the lens edge is accurately calculated to ensure that the contact surface between the edge of the lens and the opening step is uniformly adapted when the lens is placed.

[0023] A stepped groove 3 structure is formed in one step inside the lens opening 2 of the umbrella disc 1 using die stamping or CNC machining. The height and width of the step are designed according to the lens thickness and the stress distribution of the coating layer. The step surface of the stepped groove 3 forms a surface contact support with the edge of the lens body 17, which can avoid the phenomenon of coating around the lens body 17 due to stress warping and reduce the formation of color difference edges after coating. The one-piece molding technology overcomes the problem of easy deformation and detachment of traditional edge welding rods, so that the lens remains stable during the coating process.

[0024] Specifically, when using this utility model, the lens body 17 is clamped and placed in the stepped groove 3 in the lens opening 2 by the clamp. If it is necessary to lock the lens body 17 in the lens opening 2, simply align the rectangular block 7 with the limiting insertion port 6 in the notch 5 (at this time, one end of the L-shaped locking port 9 on the locking block 8 at the end of the rectangular block 7 is facing the side of the lens body 17). Then, simply push the first L-shaped locking rod 11 and the second L-shaped locking rod 12 with your fingers to make the first L-shaped locking rod 11 and the second L-shaped locking rod 12 move closer together, so that the rectangular block 7 can be inserted into the limiting insertion port 6 inside the notch 5, and thus the lens body 17 can be locked in the lens opening 2. Similarly, when disassembling, simply push the first L-shaped locking rod 11 and the second L-shaped locking rod 12 again to remove the rectangular block 7 from the limiting insertion port 6, and then the clamp that can hold the lens can be inserted into the notch 5 to clamp the lens body 17.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0026] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
