Description

Technical Field

[0001] This utility model relates to the field of optical filter coating technology, specifically to an anti-displacement fixture for optical communication filter coating. Background Technology

[0002] Filter coating is achieved by depositing multiple thin films on the surface of an optical substrate to allow or block light of a specific wavelength. The core processes include vacuum coating and chemical coating, and it is widely used in fields such as cameras and medical devices.

[0003] Existing optical communication filter coating fixtures are relatively simple in function, and most require manual loading and unloading, which is time-consuming and labor-intensive. They cannot automatically feed and unload optical communication filter materials, nor can they perform anti-drop clamping operations according to different specifications of optical communication filters, which can easily lead to phenomena such as displacement of optical communication filters during the coating process.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent announcement number: CN221854758U, publication date: 2024-10-18) discloses an optical communication filter coating fixture. The technical problem is that during the use of the coating fixture, the optical communication filter material cannot be automatically fed and unfed, and it cannot be clamped to prevent detachment according to different specifications of the optical communication filter. This leads to problems such as the optical communication filter easily shifting during the coating process. The technical solution is: an optical communication filter coating fixture, including a fixture fixing base plate, support legs, a pressure control plate, a material transport component, an adjustment and rotation placement component, two-sided locking and fixing components, a first protective support frame plate, and a lifting and sealing coating component. This optical communication filter coating fixture can automatically feed and unfed the optical communication filter material by setting the material transport component, and the two-sided locking and fixing components can adjust and clamp according to different specifications of the optical communication filter material to prevent shifting during the coating process.

[0005] While the above design can solve the aforementioned problems, the clamping design is insufficient and the position may shift when the filter is clamped, resulting in an incomplete processing effect of the finished product and reducing the processing efficiency of the equipment. At the same time, the existing design is not convenient for coating operation, and the docking trajectory will deviate after long-term operation, resulting in insufficient processing effect of the equipment. In addition, the single processing stroke is long and the processing efficiency is slow. Utility Model Content

[0006] The purpose of this utility model is to provide an anti-displacement fixture for optical communication filter coating, so as to solve the problems mentioned in the background art, where the position of the filter is offset due to insufficient clamping design when clamping it, resulting in an incomplete processing effect of the finished product and reduced processing efficiency of the equipment. At the same time, the existing coating operation is not convenient enough, and the docking trajectory will deviate after long-term operation, resulting in poor processing effect of the equipment. In addition, the single processing stroke is long and the processing efficiency is slow.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixture for preventing offset during optical communication filter coating, comprising a bottom support base, a support processing plate mounted on the upper surface of the bottom support base, and an anti-offset support mechanism for clamping the filter body mounted above the support processing plate, the anti-offset support mechanism comprising a transverse sliding frame, the transverse sliding frame being fixedly mounted on the upper surface of the support processing plate, a lifting limit frame mounted on the upper surface of the bottom support base, and a traction docking mechanism for coating the filter body being installed inside the lifting limit frame.

[0008] Furthermore, the traction docking mechanism includes a rotation drive motor, which is fixedly installed on the inner surface of the lifting limit frame. An eccentric rotating wheel is installed on the outer surface of the output end of the rotation drive motor, and an interlocking docking plate is installed on the outer surface of the eccentric rotating wheel.

[0009] Furthermore, a pressing docking plate is installed on the outer surface of the mating docking plate, and a limiting sliding rod is installed on the upper surface of the pressing docking plate. The limiting sliding rod is nested inside the top of the lifting limiting frame, and right-angle connecting rods are installed on the left and right sides of the top of the pressing docking plate.

[0010] Furthermore, the filter body is nested inside the transverse sliding frame, and a sliding traction rod is installed inside the supporting processing plate. Rotating connecting rods are installed on the left and right sides of the front end of the sliding traction rod, and rotating gear rods are installed on the left and right sides of the upper surface of the supporting processing plate.

[0011] Furthermore, the other end of the rotating connecting rod is rotatably mounted on the end of the rotating gear rod, and a sliding clamping plate is installed on the outer surface of the transverse sliding frame. An integral meshing rack is installed on the outer surface of the sliding clamping plate, and the integral meshing rack meshes with the rotating gear rod.

[0012] Furthermore, the inward sliding trajectory of the sliding clamping plate corresponds to and fits with the left and right sides of the filter body, and a stabilizing compression spring is installed on the upper surface of the supporting processing plate. The front end of the stabilizing compression spring is fixedly installed on the side of the sliding clamping plate, and two sets of sliding clamping plates, integrated meshing racks and stabilizing compression springs are symmetrically installed about the center point of the sliding traction rod.

[0013] Furthermore, the ends of the right-angle connecting rods are rotatably mounted on the corresponding left and right sides of the support processing plate, and the downward movement trajectory of the pressing docking plate corresponds to the installation position of the filter body. The left and right sides of the support processing plate are slidably mounted inside the lifting limit frame, and the outer surface of the lifting limit frame contacts the inside of the limiting sliding rod to form a sliding structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are: When the optical communication filter coating anti-displacement fixture needs to clamp the filter body, the sliding traction rod is pulled forward so that the rotating connecting rod drives the integrated meshing rack to rotate through the rotating gear rod until the sliding clamping plate moves to the appropriate position and is placed into the interior of the horizontal sliding frame. This design ensures that there will be no positional displacement when the filter needs to be clamped, making the processing effect of the finished product more comprehensive and improving the processing efficiency of the equipment.

[0015] Furthermore, when it is necessary to perform a coating operation on the filter body, the rotation drive motor is directly started, so that the eccentric rotating wheel drives the lower pressing plate up and down through the interlocking plate. This design improves the convenience of the coating operation of the equipment, and there will be no deviation in the docking trajectory after long-term work, reducing the processing stroke of a single operation and improving processing efficiency.

[0016] Furthermore, during the movement of the lower pressure docking plate, the supporting processing plate is moved upward as a whole through the right-angle connecting rod. This design improves the docking efficiency between the filter body and the lower pressure docking plate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: a fixture for preventing offset during optical communication filter coating, comprising a bottom support base 1, a support processing plate 2 mounted on the upper surface of the bottom support base 1, and an anti-offset support mechanism for clamping the filter body 8 mounted above the support processing plate 2, the anti-offset support mechanism including a transverse sliding frame 7, such as... Figure 3 As shown, the transverse sliding frame 7 is fixedly installed on the upper surface of the support processing plate 2, and the upper surface of the bottom support seat 1 is equipped with a lifting limit frame 3, and the interior of the lifting limit frame 3 is equipped with a traction docking mechanism for coating the filter body 8.

[0026] like Figure 2 , Figure 3 and Figure 4 The technical solution shown addresses the problem that insufficient clamping design during filter clamping can lead to positional misalignment, resulting in incomplete finished product processing and reduced equipment efficiency. The solution discloses the following: the filter body 8 is nested inside the transverse sliding frame 7; a sliding traction rod 4 is installed inside the supporting processing plate 2; rotating connecting rods 5 are installed on the left and right sides of the front end of the sliding traction rod 4; rotating gear rods 6 are installed on the left and right sides of the upper surface of the supporting processing plate 2; the other end of the rotating connecting rod 5 is rotatably mounted at the end of the rotating gear rod 6; and a sliding clamping plate 9 is installed on the outer surface of the transverse sliding frame 7. Figure 4As shown, an integral meshing rack 10 is installed on the outer surface of the sliding clamping plate 9, and the integral meshing rack 10 meshes with the rotating gear rod 6. The inward sliding trajectory of the sliding clamping plate 9 corresponds to and fits with the left and right sides of the filter body 8. A stabilizing compression spring 11 is installed on the upper surface of the supporting processing plate 2. The front end of the stabilizing compression spring 11 is fixedly installed on the side of the sliding clamping plate 9. Two sets of sliding clamping plates 9, integral meshing rack 10 and stabilizing compression spring 11 are symmetrically installed about the center point of the sliding traction rod 4.

[0027] When it is necessary to perform a stable clamping operation on both sides of the filter body 8, the sliding traction rod 4 is directly fixed and slid forward along the inside of the support processing plate 2. Since the support processing plate 2 is fixedly installed on the upper surface of the bottom support base 1, the sliding traction rod 4 will drive the two sets of rotating connecting rods 5 that are rotatably installed on the left and right sides of its top during the sliding process. Since the ends of the rotating connecting rods 5 are also rotatably installed on the ends of the rotating gear rods 6, and the center of the rotating gear rods 6 is rotatably installed on the upper surface of the support processing plate 2, the rotating gear rods 6 will perform a limited circumferential rotation as driven by the rotating connecting rods 5. During the rotation of the rotating gear rods 6, they will abut against the integrated meshing rack 10 that is in contact with the outside and generate a meshing motion, such as Figure 4 As shown, since the integrated meshing rack 10 is fixedly installed on the outer surface of the sliding clamping plate 9, and the sliding clamping plate 9 is slidably installed on the outside of the transverse sliding frame 7 fixedly installed above the support processing plate 2, the integrated meshing rack 10 and the sliding clamping plate 9 will slide laterally along the outside of the transverse sliding frame 7 as driven by the meshing movement. During the outward sliding process of the sliding clamping plate 9, the externally fixed stabilizing compression springs 11 will be correspondingly compressed and contracted until the left and right sets of sliding clamping plates 9 move to the appropriate processing gap. At this time, the filter body 8 can be directly placed into the inside of the transverse sliding frame 7. Then, the sliding traction rod 4 can be released and the stabilizing compression springs 11 can be reset due to their own elasticity to complete the external fixation of the filter body 8. This design makes the use of the equipment more stable and faster.

[0028] Example 2: Figure 1 , Figure 5 and Figure 6 The technical solution shown addresses the shortcomings of existing coating designs, such as insufficient ease of operation, deviations in the docking trajectory after prolonged use leading to inadequate processing results, and long single-processing strokes resulting in slow processing efficiency. The solution discloses a traction docking mechanism comprising a rotary drive motor 12, which is fixedly mounted on the inner surface of the lifting limit frame 3. An eccentric rotary wheel 14 is mounted on the outer surface of the output end of the rotary drive motor 12, and a mating docking plate 15 is mounted on the outer surface of the eccentric rotary wheel 14. Figure 5As shown, a pressing docking plate 13 is installed on the outer surface of the mating docking plate 15, and a limiting sliding rod 16 is installed on the upper surface of the pressing docking plate 13. The limiting sliding rod 16 is nested inside the top of the lifting limiting frame 3, and right-angle connecting rods 17 are installed on the left and right sides of the top of the pressing docking plate 13. The ends of the right-angle connecting rods 17 are rotatably installed on the corresponding left and right sides of the supporting processing plate 2, and the downward movement trajectory of the pressing docking plate 13 corresponds to the installation position of the filter body 8. The left and right sides of the supporting processing plate 2 are slidably installed inside the lifting limiting frame 3, and the outer surface of the lifting limiting frame 3 contacts the inside of the limiting sliding rod 16 to form a sliding structure.

[0029] When an external coating operation is required on the filter body 8, the rotation drive motor 12 fixedly installed inside the lifting limit frame 3 is started directly. The rotation drive motor 12 then synchronously rotates the eccentric rotating wheel 14 fixedly installed on the outer surface of the output end. Since the eccentric rotating wheel 14 is nested inside the mating plate 15, the mating plate 15 will move vertically up and down as driven. Because the mating plate 15 is nested inside the pressing plate 13, the pressing plate 13 will also move vertically up and down as driven. During the movement of the pressing plate 13, the limiting sliding rod 16 fixedly installed at the top will be synchronously driven. Figure 6 As shown, since the limiting sliding rod 16 is nested and slidably installed inside the top of the lifting limiting frame 3, the pressing docking plate 13 will move vertically in sync. During the downward movement of the pressing docking plate 13, the right-angle connecting rods 17, which are rotatably installed at the top left and right ends, will be driven synchronously. Since the middle section of the right-angle connecting rod 17 is rotatably installed at the top of the lifting limiting frame 3, and the end of the right-angle connecting rod 17 is rotatably installed on the left and right sides of the support processing plate 2, the support processing plate 2 and the filter body 8 will slide vertically upward along the inside of the lifting limiting frame 3 until the filter body 8 and the pressing docking plate 13 complete the docking and coating operation. This design improves the processing efficiency of the equipment.
