[0002] During the mirror coating process of the evaporation coating machine, the coating needs to be positioned on the planetary disk at different angles using an umbrella frame to simulate the curvature of the coating surface. However, the current umbrella frame simulation form is difficult to meet the ever-changing coating accuracy and modeling requirements, and cannot cope with large curvature mirror coating. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and solve the problem that the prior art is difficult to satisfy the placement of large curvature mirror coatings.

[0004] In order to achieve the above-mentioned purpose of the invention, a mirror simulation tooling with adjustable curvatures is provided, including a large circular ring seat, a crossbeam is fixed under the large circular ring seat, the projection of the crossbeam on the surface of the large circular ring seat is located on the diameter line of the large circular ring seat, a telescopic rod is vertically arranged on the crossbeam, a ball joint support is fixed at the end of the telescopic rod, and a lens support block for simulating the local angle of the mirror is fixed on the top of the ball joint support.

[0005] The telescopic rod referred to herein is used to adjust the distance between the ball joint support and the cross beam, and can be in the form of a sleeve-type telescopic rod, a stud threaded on the cross beam, etc. The ball joint support described herein can be commercially available or self-made by a person skilled in the art.

[0006] Preferably, at least three ball joint supports are arranged in the length direction of the beam.

[0007] The spherical joint supports referred to herein can cooperate to simulate the curvature of the mirror surface after adjusting the height and the angle of the lens support block.

[0008] Preferably, the crossbeam is provided with a slide groove along the length direction, and the ball joint support is slidably arranged on the slide groove.

[0009] Preferably, it also includes a telescopic rod in the form of a threaded rod; a slider is provided in the slide groove, and the slider has threaded holes I with a spacing of a; threaded holes II with a spacing of a are provided at the bottom of the ball joint support; and both ends of the threaded rod are screwed into the threaded holes I and II respectively.

[0010] The threaded rod referred to herein can adjust the distance between the ball joint support and the crossbeam by rotating; in specific form, the thread directions of threaded hole I and threaded hole II may be opposite, and the thread of the threaded rod may be unidirectional; or the thread directions of threaded hole I and threaded hole II may be the same, and the threaded rod may be provided with threads of different directions on both sides.

[0011] Preferably, a nut for clamping and fixing the bottom of the ball joint support or the sliding block is threadedly connected to the threaded rod.

[0012] The nuts referred to here are set in quantity as required.

[0013] Preferably, a support rod is vertically provided between the large circular ring seat and the cross beam; one end of the support rod is fixed to the lower side of the large circular ring seat, and the other end is passed through the hole of the cross beam, a threaded positioning through hole is provided on the side of the hole, and a positioning bolt is screwed into the threaded positioning through hole.

The telescopic rod and the ball joint support can simulate the curvature of the mirror at various heights and angles, so that the top support surface can be simulated and set more accurately.

[0017] By setting the slide groove, the eccentricity of the ball joint support relative to the large circular ring seat can be adjusted, so as to better simulate a specific surface shape.

[0018] The special arrangement of the threaded holes prevents uncontrolled rotation of the ball joint support during adjustment of the telescopic rod, thereby avoiding multiple adjustment confirmations due to uncontrolled rotation.

[0019] The height of the ball joint support relative to the large circular ring seat can be easily adjusted through the special fixing form of the large circular ring seat and the crossbeam.

[0020] The beneficial effects of the present invention are that it can perfectly simulate the placement of the mirror area of ​​the product coating, facilitate the analysis and understanding of the data of the product area, improve the coating angle, and reduce the tooling limitations of the coating machine caused by the design of film layers with different curvatures.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] according to Figures 1 to 4 A mirror simulation tooling with adjustable curvatures is shown, comprising a large circular ring seat 1, a crossbeam 3 is fixed below the large circular ring seat 1, and the projection of the crossbeam 3 on the surface of the large circular ring seat is located on the diameter line of the large circular ring seat. The crossbeam 3 is provided with a slide groove along the length direction, and a slider 8 is slidably arranged on the slide groove, and a threaded rod perpendicular to the crossbeam is erected on the slider 8, and a ball joint support is fixed at the end of the threaded rod. The slider 8 is provided with threaded holes I with a spacing of a; the bottom of the ball joint support is provided with threaded holes II with a spacing of a; the two ends of the threaded rod are screwed into the threaded holes I and II respectively. Nuts for clamping and fixing the bottom of the ball joint support and for clamping and fixing the slider are screwed onto the threaded rod. Three ball joint supports are arranged in the length direction of the crossbeam 3.

[0031] A support rod 2 is vertically arranged between the large circular seat 1 and the cross beam 3; one end of the support rod 2 is fixed to the lower side of the large circular seat 1, and the other end is passed through the hole of the cross beam 3, and a threaded positioning through hole is provided on the side of the hole, and a positioning bolt is screwed into the threaded positioning through hole.

[0032] The ball joint support is composed of a lens top block 4, a lens fixing block 6, and a sliding rotating ball 7; the lens fixing block 6 is provided with a receiving groove for accommodating the sliding rotating ball 7, and is fixed to the threaded rod at the bottom; the lens top block 4 is in the shape of a plate, and a fixing rod passes through the bottom of the lens top block 4, and the end of the fixing rod passes through the sliding rotating ball 7 for fixing, and a lens support block 5 for simulating the local angle of the mirror surface is attached and fixed to the top surface of each lens top block 4.

[0033] When in use, first lock the two support rods 2 on the two threaded holes of the large circular ring seat 1, then place the crossbeam 3 on the support rods 2 and lock it, and then use the slider 8 to adjust the position of the lens fixing block 6 through the threaded rod, and adjust the direction of each lens top block 4 respectively. Finally, after fixing, the simulated coating tooling is realized.

[0034] The mirror simulation tooling is designed for the evaporation coating of mirrors with different curvatures and some optical concave, convex and flat circular glass products with a length not exceeding 400mm. The coating surface originally fixed on the planetary disk umbrella frame can be adjusted to a large curvature convex surface (such as Figure 2 as shown) or concave (as Figure 3 as shown) and the horizontal state (as Figure 1 As shown); the height of the coated mirror surface can be simulated arbitrarily by adjusting the height of the two support rods 2, which greatly reduces the limitation of the coating uniformity that cannot be analyzed during the debugging process due to the special curvature of the product. By adjusting the height and angle of the coating, the curvature of the product in the coating process can be simulated, so as to obtain data on the lens in different curvature directions, whether each film layer area meets the required effect, and use it to correct the uniform baffle.

[0035] Compared with the traditional fixed tooling, this tooling can simulate the mirror surfaces of components with different curvatures and different sizes; it is easy to process, stable to use, and not easy to deform, and is particularly suitable for verifying the uniformity of large curvature mirrors; it can also be used with a hoisting structure to effectively solve the problem of film thickness that cannot be verified at various angles of large curvature mirrors. After using this mirror simulation tooling, a perfect uniform coating baffle can be corrected according to the product size and image requirements to avoid the phenomenon of uneven film layers at various angles when coating large lenses; this mirror simulation tooling can effectively improve work efficiency, reduce fixture manufacturing costs, has high versatility, low scrap rate, and short processing cycle, and is particularly suitable for small-batch production.

[0036] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
