Description

Technical Field

[0001] This utility model relates to the field of optical lens manufacturing technology, specifically to a coating device for neutral density filters. Background Technology

[0002] A neutral density (ND) filter is an optical filter used in photography. By uniformly reducing the intensity of light entering the lens without altering color balance, it helps photographers achieve special shooting effects in bright light conditions. Modern optical filters are typically coated with single or multiple layers of protective coatings. The main reason for these coatings on ND filters is to improve optical performance and enhance durability.

[0003] The coating process of neutral density (ND) lenses is generally carried out in a coating device. The operator first installs the ND lens on the placement slot of the placement plate, then places it on the placement rack in the coating device, and finally emits the coating material through the coating emission source so that the material adheres to the surface of the ND lens to form a thin film, thereby completing the coating of the lens.

[0004] However, existing coating devices can only coat one side of the neutral density filter at a time. After one side of the filter is coated, the staff has to remove the placement plate from the coating device, flip it over, and then install it on the placement rack so that the coating emission source can coat the other side of the neutral density filter. This operation is cumbersome and inefficient. In addition, removing the placement plate from the coating device and manually flipping it can easily contaminate the surface of the filter and affect the coating quality. Utility Model Content

[0005] This invention aims to solve some problems existing in the prior art. Therefore, the purpose of this invention is to provide a coating device for neutral density (ND) filters, wherein the placement plate of the coating device can be automatically flipped to coat both sides of the ND filter, thereby increasing work efficiency.

[0006] To achieve the above objectives, this utility model employs the following technical solution: A coating device for neutral density filters, comprising: Main body of the device; A coated emission source, located on the top of the device body, is used to emit coated material; A placement plate, located inside the main body of the device, on which multiple neutral density filters can be placed; A flipping mechanism is provided to drive the placement plate to flip. The flipping mechanism includes a motor, a first mounting bracket, and a second mounting bracket. The motor is located outside the main body of the device. The first mounting bracket is located inside the main body of the device and is fixedly connected to the rotating shaft of the motor. The second mounting bracket is located inside the main body of the device and is rotatably mounted on the main body of the device. Both the first mounting bracket and the second mounting bracket have mounting slots inside. The placement plate is installed in the mounting slots of the first mounting bracket and the second mounting bracket.

[0007] Furthermore, it also includes a locking mechanism, which is installed at one end of the first mounting bracket and the second mounting bracket to lock the placement plate. The locking mechanism includes a base, a bolt and a nut. The base is located on the first mounting bracket and the second mounting bracket. The bolt is rotatably installed in the base and the nut is rotatably installed on the bolt. The first mounting bracket and the second mounting bracket are provided with through slots for the bolt to rotate.

[0008] Furthermore, the first mounting bracket and the second mounting bracket are provided with locking parts at the opposite end to the locking mechanism.

[0009] Furthermore, the placement plate includes a first placement plate and a second placement plate, with the first placement plate covering the second placement plate. Both the first and second placement plates have multiple evenly distributed placement slots, and the placement slots on the first and second placement plates are positioned correspondingly. A placement platform is provided in each placement slot.

[0010] Furthermore, the placement platform is arc-shaped and there are multiple platforms.

[0011] Furthermore, the placement platform is annular.

[0012] Furthermore, a plurality of magnets are provided on the outer periphery of the first placement plate, and a plurality of mating parts are provided on the outer periphery of the second placement plate. The mating parts correspond to the positions of the magnets and are attracted to each other.

[0013] Furthermore, the first or second placement plate has a groove.

[0014] Furthermore, the first placement plate has an alignment groove, and the second placement plate has an alignment protrusion, the alignment protrusion being adapted to the alignment groove.

[0015] Furthermore, the main body of the device is provided with an openable door panel.

[0016] Compared with the prior art, the beneficial effects of this utility model are: The placement plate can be directly installed on the flipping mechanism, which can then automatically flip the placement plate and the neutral density filter to coat both sides of the neutral density filter, thereby improving the efficiency of lens coating and making it highly practical.

[0017] 2. The neutral density filter is placed in the placement plate and fixed by the placement stage on the first and second placement plates. This can prevent the neutral density filter from accidentally falling off the placement plate during the coating and flipping process, which would affect the coating efficiency.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0024] like Figure 1-6 As shown, a coating apparatus for neutral density filters includes a main body 1, a coating emission source 2, a placement plate 3, a flipping mechanism 4, and a locking mechanism 5. The coating emission source 2 is located at the top of the main body 1 and is used to emit coating material; the placement plate 3 is located inside the main body 1 and can hold multiple neutral density filters 6; the flipping mechanism 4 drives the placement plate 3 to flip automatically, thereby automatically flipping the neutral density filters 6 to accelerate the coating process; the locking mechanism 5 locks the placement plate 3, fixing it in place and ensuring the normal operation of the coating process.

[0025] In this embodiment, the coated emission source 2 is existing technology, so it will not be described in detail in this application.

[0026] Please refer to Figure 2 and 3Specifically, the flipping mechanism 4 includes a motor 401, a first mounting bracket 402, and a second mounting bracket 403. The motor 401 is fixedly mounted on the outside of the main body 1 of the device. The first mounting bracket 402 is located inside the main body 1 of the device and is fixedly connected to the rotating shaft of the motor 401. The second mounting bracket 403 is located inside the main body 1 of the device and can be rotatably mounted on the main body 1 of the device. Both the first mounting bracket 402 and the second mounting bracket 403 have mounting grooves 404 inside. The mounting grooves 404 pass through one end of the first mounting bracket 402 and the second mounting bracket 403, but not through the other end. The placement plate 3 is installed in the mounting grooves 404 of the first mounting bracket 402 and the second mounting bracket 403. When the motor 401 works, it drives the first mounting bracket 402 to rotate, which in turn drives the placement plate 3 and the neutral density filter 6 to rotate, thereby playing an automatic flipping role so that both sides of the neutral density filter 6 can be coated, which can improve the working efficiency of lens coating. At the same time, the second mounting bracket 403 will also rotate.

[0027] The first mounting bracket 402 and the second mounting bracket 403 adopt a symmetrical design, which can effectively share the dynamic load during the flipping process and avoid excessive force on one side, which could lead to deformation or increased wear of the mechanism.

[0028] In this embodiment, the motor 401 is a geared motor 401.

[0029] In this embodiment, bearings are installed at the contact positions between the first mounting bracket 402, the second mounting bracket 403 and the side wall of the device body 1, which can reduce friction and support rotation.

[0030] Please refer to Figure 3 and 4 Specifically, the locking mechanism 5 is installed at the end of the first mounting bracket 402 and the second mounting bracket 403 that is not penetrated by the mounting groove 404. The locking mechanism 5 includes a base 501, a bolt 502, and a nut 503. The base 501 is located on the first mounting bracket 402 and the second mounting bracket 403 and is an integral structure with the first mounting bracket 402 and the second mounting bracket 403. The bolt 502 is rotatably installed in the base 501 through a connecting shaft, and the nut 503 is rotatably installed on the bolt 502. The frame 402 and the second mounting frame 403 are provided with through slots 405 for the rotation of bolt 502, which facilitates the rotation of bolt 502. After the placement plate 3 is placed into the mounting slot 404, the bolt 502 is rotated downwards to make it vertical in the through slot 405. Then, the nut 503 is rotated so that the end face of the nut 503 is in contact with the lower surface of the first mounting frame 402 or the second mounting frame 403, and the bolt 502 is locked by friction. Thus, one end of the placement plate 3 is locked by the bolt 502.

[0031] In this embodiment, the nut 503 is a wing nut 503, so that the operator can rotate it.

[0032] Please refer to Figure 4 The first mounting bracket 402 and the second mounting bracket 403 are provided with a locking part 406 at the other end opposite to the locking mechanism 5. The locking part 406 blocks the other end of the mounting groove 404, that is, the other end of the placement plate 3 is locked by the locking part 406, and cooperates with the locking mechanism 5 to complete the limiting of the placement plate 3 in the mounting groove 404.

[0033] In this embodiment, the width of the placement plate 3 is equal to the distance between the locking part 406 and the bolt 502, and the height of the placement plate 3 is equal to the height of the mounting groove 404.

[0034] Please refer to Figure 5 and 6 The placement plate 3 includes a first placement plate 301 and a second placement plate 302. The first placement plate 301 covers the second placement plate 302. Both the first placement plate 301 and the second placement plate 302 have multiple evenly distributed placement slots 303. The placement slots 303 on the first placement plate 301 and the second placement plate 302 are positioned correspondingly. A placement platform 304 is provided in the placement slot 303. The neutral density filter 6 is placed on the placement platform 304 of the first placement plate 301. The second placement plate 302 is then closed. Under the action of the placement platform 304 of the second placement plate 302, the neutral density filter 6 is pressed and fixed, which can prevent the neutral density filter 6 from accidentally falling off the placement plate 3 during the coating and flipping process, thereby affecting the coating efficiency.

[0035] In this embodiment, the placement stage 304 is made of flexible rubber and is glued to the placement groove 303 with adhesive. The flexible rubber material is not easy to leave scratches on the neutral density filter 6.

[0036] In this embodiment, the placement stage 304 is arc-shaped and there are multiple stages. Specifically, there are three placement stages 304 that are evenly distributed. The central angle of the placement stage 304 is 50°. The arc-shaped placement stage 304 can reduce the contact area with the neutral density filter 6 and is less likely to damage the neutral density filter 6.

[0037] In some other feasible embodiments, the placement stage 304 is annular.

[0038] Please refer to Figure 5 and 6 The first placement plate 301 has a plurality of magnets 305 on its outer periphery, and the magnets 305 are embedded in the first placement plate 301. The second placement plate 302 has a plurality of mating parts 306 on its outer periphery, and the mating parts 306 are positioned corresponding to and attracted to the magnets 305. In this way, the second placement plate 302 can be fixed on the first placement plate 301 by the attraction between the magnets 305 and the mating parts 306.

[0039] In this embodiment, the mating part 306 is a metal that can be attracted by the magnet 305, specifically iron.

[0040] In some other feasible embodiments, the mating component 306 is a magnet 305, that is, the first placement plate 301 and the second placement plate 302 are fixed together by the attraction of their opposite poles.

[0041] Please refer to Figure 6 The first placement plate 301 or the second placement plate 302 is provided with a groove 307. The groove 307 is designed so that the workers can apply force to the first placement plate 301 or the second placement plate 302 to separate the two.

[0042] In this embodiment, the groove 307 is located on the second placement plate 302.

[0043] Please refer to Figure 5 and 6 The first placement plate 301 has an alignment groove 308, and the second placement plate 302 has an alignment protrusion 309. The alignment groove 308 and the alignment protrusion 309 are arranged around the first placement plate 301 and the second placement plate 302. The alignment protrusion 309 is adapted to the alignment groove 308. By aligning the alignment protrusion 309 with the alignment groove 308, the alignment of the first placement plate 301 and the second placement plate 302 is ensured.

[0044] Please refer to Figure 1 The main body 1 of the device is provided with an openable door panel 101. The door panel 101 is connected to the main body 1 of the device via hinges. The door panel 101 is opened to allow the installation of the plate 3.

[0045] This utility model relates to a coating device for neutral density filters, and its working principle is explained in conjunction with the accompanying drawings: First, open the placement plate 3 and place the neutral density filter 6 into the placement slot 303 of the first placement plate 301, positioned on the placement stage 304. Then, close the second placement plate 302 and fix them together magnetically. Use the placement stages 304 on the first and second placement plates 301 and 302 to press the neutral density filter 6 firmly. Then, install the placement plate 3 into the mounting slot 404, rotate the bolt 502 to make it stand upright in the through slot 405, and tighten the nut 503 to press the first mounting bracket 402 and the second mounting bracket 403. Fix the placement plate 3 with the bolt 502. Start the coating emission source 2 to coat one surface of the neutral density filter 6. After a certain period of time (set according to the actual situation), start the motor 401 to drive the first mounting bracket 402 to rotate, which in turn drives the placement plate 3, the neutral density filter 6, and the second mounting bracket 403 to rotate 180° to coat the other surface of the neutral density filter 6.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
