Description

Technical Field

[0001] This utility model belongs to the field of optical coating equipment, and in particular relates to an optical coating device. Background Technology

[0002] In the field of optical component processing, lens coating is an important step in optimizing its core performance such as light transmittance and abrasion resistance. For applications with low coating precision requirements (such as some industrial lenses and general optical accessories), existing optical coating equipment still suffers from insufficient adaptability, making it difficult to balance the relationship between basic coating requirements and production efficiency and cost control.

[0003] Existing equipment designed for low- to medium-precision coating generally suffers from weak batch processing capabilities. Most devices can only hold 1-2 lenses at a time, and the lens mounting structure is complex, requiring multiple sets of bolts or clips for individual fixing, making disassembly and assembly time-consuming and labor-intensive. After coating one side of a lens, it must be manually disassembled, flipped, and re-fixed before coating the other side, making the entire process cumbersome and unable to meet the efficiency requirements of small- to medium-batch production. Furthermore, the lens clamping structure of these devices has poor versatility, only able to hold lenses of a single specification. When processing lenses of different diameters or thicknesses, the entire clamping assembly must be replaced.

[0004] In summary, in applications where coating precision requirements are not high, existing optical coating devices suffer from problems such as low batch processing efficiency, poor lens clamping versatility, and insufficient ease of operation. There is an urgent need for an optical coating device that is simple in structure, highly versatile, and can meet the basic coating efficiency and quality requirements to adapt to production applications in such scenarios.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 3 As shown, an optical coating device includes a housing 1, a rotating rod 2 horizontally arranged inside the housing 1, a plurality of connecting seats 3 arranged side by side on the rotating rod 2, a clamping frame 4 horizontally fixed to the connecting seats 3, the clamping frame 4 being able to rotate and flip with the rotating rod 2, and a movable seat 5 that can move horizontally along the length direction of the rotating rod 2 is also provided inside the housing 1, the bottom of the movable seat 5 being fixedly connected to a nozzle 6 located above the clamping frame 4. In this embodiment, multiple connecting seats 3 are provided on the rotating rod 2, and each connecting seat 3 is provided with a clamping frame 4. In use, the lens is installed on the clamping frame 4 so that the front and back of the lens are exposed. In the initial state, the clamping frame 4 is in a horizontal state, so the lens is also in a horizontal state. The moving seat 5 is moved to drive the nozzle 6 to move, thereby coating the upper surface of the lenses in the same row. Then, the clamping frame 4 is flipped by the rotating rod 2 to make the lens rotate 180°. At this time, the upper surface of the lens is the lower surface of the lens in the original position. The nozzle 6 is moved again to perform coating, thus completing the coating operation on the front and back of the lens.

[0033] The clamping frame 4 is a U-shaped structure with an outward opening, and includes a fixed part 401 and a moving part 402, both of which are L-shaped and arranged opposite to each other. The horizontal section of the fixed part 401 is horizontally fixed to the outer wall of the connecting seat 3, and a connecting groove 4011 is provided at the end of the horizontal section of the fixed part 401. The horizontal section of the moving part 402 is connected in the connecting groove 4011 and can move along the length direction of the connecting groove 4011. The vertical section of the moving part 402 and the vertical section of the fixed part 401 are parallel and arranged outward.

[0034] The connecting groove 4011 has a square cross-section. A spring is fixed between the bottom end of the connecting groove 4011 and the end of the horizontal section of the moving part 402. When the vertical section of the moving part 402 is in contact with the end of the horizontal section of the fixed part 401, the spring is in an extended state. This ensures that when the moving part 402 is pulled away from the fixed part 401 and the lens is clamped between the vertical section of the fixed part 401 and the vertical section of the moving part 402, the spring is always in an extended state, so that the lens can be stably clamped in the clamping frame 4. In this embodiment, one end of the spring is fixed to the bottom end of the connecting groove 4011, and the other end is fixed to the end of the horizontal section.

[0035] The vertical section of the fixing part 401 has a first arc-shaped groove 4012 on its inner side, and the vertical section of the moving part 402 has a second arc-shaped groove 4021 on its inner side. The first arc-shaped groove 4012 and the second arc-shaped groove 4021 are arranged opposite to each other, and a rubber layer 15 is provided in both the first arc-shaped groove 4012 and the second arc-shaped groove 4021. In this embodiment, the rubber layer 15 is bonded and fixed in the first arc-shaped groove 4012 and the second arc-shaped groove 4021. The lens (which may have a protective frame arranged circumferentially along the outer side of the lens, on the one hand, provides a more stable connection and limiting function for clamping the lens, and on the other hand, can shield the edge of the lens, eliminating the need for coating the edge of the lens) is clamped by the vertical section of the fixing part 401 and the vertical section of the moving part 402, and the rubber layer 15 provides protection to prevent wear on the lens or the protective frame on the outer side of the lens.

[0036] The rotating rod 2 is a cylindrical structure. A first motor 9 is fixedly connected to the outer wall of the housing 1. The output shaft of the first motor 9 is fixedly connected to one end of the rotating rod 2. The connecting seat 3 is a tubular structure. A strip-shaped protrusion 201 integrally formed with the rotating rod 2 is provided along the length direction of the rotating rod 2. A strip-shaped snap-fit ​​groove 301 is opened on the inner side of the connecting seat 3 corresponding to the strip-shaped protrusion 201. The connecting seat 3 is sleeved on the rotating rod 2, and the strip-shaped protrusion 201 is snapped into the snap-fit ​​groove 301 to achieve circumferential positioning of the connecting seat 3. In this embodiment, the other end of the rotating rod 2 is connected to the side wall of the housing 1 by a bearing. The first motor 9 drives the rotating rod 2 to rotate, thereby causing the lens to flip. In this embodiment, the first motor 9 drives the rotating rod 2 to rotate 180° each time to ensure that the clamping frame 4 is in a horizontal state, thereby ensuring that the lens is in a horizontal state, which facilitates uniform coating.

[0037] A protective layer (not shown in the figure) is provided on the inner wall of the connecting seat 3. The protective layer is made of rubber, which can effectively increase the friction between the connecting seat 3 and the rotating rod 2, and prevent the connecting seat 3 from moving back and forth without external force.

[0038] C-shaped retaining rings 11 are engaged on the side of the rotating rod 2 away from the strip-shaped protrusion 201 and at both ends of each connecting seat 3. In this embodiment, the retaining rings 11 are made of spring steel, nylon, polyethylene or thermoplastic elastomer, and have a certain degree of elastic deformation. The retaining rings 11 are fastened to the rotating rod 2 to limit the horizontal movement of the connecting seat 3.

[0039] Each connecting seat 3 has clamping frames 4 on both the front and rear sides, enabling simultaneous coating of two rows of lenses and improving coating efficiency. Inside the housing 1, between the left and right side walls, corresponding to the movable seat 5, horizontally arranged screws 7 and guide rods 8 are located. A second motor 10 is fixedly connected to the screw 7 on the outer wall of the housing 1. The output shaft of the second motor 10 is fixedly connected to the screw 7. The movable seat 5 is screwed to the screw 7 and sleeved with the guide rod 8. Two nozzles 6 are fixedly connected to the bottom of the movable seat 5, corresponding to the front and rear rows of clamping frames 4. Both nozzles 6 are connected to branch hoses 14. The other end of the branch hoses 14 is connected to the main hose 16 inside the housing 1 via a three-way valve. The other end of the main hose 16 extends out of the housing 1 and connects to the storage bin (not shown in the figure). Figure 2 As shown, Figure 2 The branch hose 14 and the main hose 16 are not shown in the figure. In this embodiment, the other end of the screw 7 is connected to the housing 1 by a bearing to facilitate the rotation of the screw 7. In this embodiment, a switch valve is provided at the outlet of the storage tank. The coating in the storage tank is drawn by a liquid pump and sprayed out through the nozzle 6 to achieve coating on the surface of the lens. In this embodiment, the nozzle 6 is a vapor deposition nozzle, which is a conventional device used in the art and has not been modified. Therefore, its principle and structure will not be described in detail here. In this embodiment, the length of the branch hose 14 in the housing 1 is sufficient to drive the nozzle 6 to move when the moving seat 5 moves horizontally; a through hole is opened at the top of the housing 1, through which the main hose 16 is installed, and a sealing ring (not shown in the figure) is provided between the through hole and the main hose 16.

[0040] Both the front and rear side walls of the container 1 are equipped with opening and closing doors 12 (the opening and closing door 12 on the front side of the container 1 is located at...). Figure 1 (Not shown in the diagram) This facilitates the installation of lenses on the front and rear rows of clamping frames 4. Alternatively, an opening / closing door 12 can be provided on only one side. When installing lenses, the lenses are first installed on the clamping frame 4 closest to the opening / closing door 12. Then, the first motor 9 rotates 180°, causing the clamping frame 4 to rotate 180°. At this point, the clamping frame 4 that was previously far from the opening / closing door 12 is moved to the side closer to the opening / closing door 12, and the lenses are then installed on that side of the clamping frame 4. Similarly, the same operation is performed when removing lenses. In this embodiment, after closing the opening / closing door 12, the opening / closing door 12 and the housing 1 can be sealed by the sealing strip provided on the opening / closing door 12, ensuring the closure of the internal space of the housing 1. This is a conventional technical method in the field of opening / closing doors.

[0041] The bottom of the inner side of the box 1 has a material collection trough 13 located below the rotating rod 2, which is used to collect most of the scattered materials for easy cleaning.

[0042] Support pads are provided at the four corners of the bottom of box 1.

[0043] The working process of this embodiment is as follows:

[0044] When installing a lens on the clamping frame 4, the moving part 402 is pulled outward a certain distance to place the lens horizontally between the first arc groove 4012 and the second arc groove 4021. Then the moving part 402 is released, and under the action of the spring force, the moving part 402 clamps the lens.

[0045] In use, the lens is mounted on the clamping frame 4, exposing both sides of the lens. Initially, the clamping frame 4 is horizontal, and the lens is also horizontal. The second motor 10 drives the screw 7 to rotate, causing the moving seat 5 to move horizontally along the screw 7, which in turn causes the nozzle 6 to move horizontally above the lens. The material in the storage box is sprayed out from the nozzle 6 after passing through the main hose and the branch hose 14, coating the upper surface of the lenses in the same row. Then, the first motor 9 is driven to rotate, causing the rotating rod 2 to rotate 180°, which in turn causes the clamping frame 4 and the lens to rotate 180°. At this time, the upper surface of the lens is the lower surface of the lens in the original position. The nozzle 6 is moved again to perform coating, thus completing the coating operation on both sides of the lens.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
