Description

Technical Field

[0001] This utility model relates to the field of optical lens manufacturing technology, specifically to an optical lens coating machine. Background Technology

[0002] Lens coating machines are used to coat optical lenses with a thin metal film, enabling them to achieve functions such as reducing or increasing light reflection, beam splitting, color separation, filtering, and polarization. They are commonly used facilities in the production and processing of optical lenses.

[0003] Chinese Patent CN219824345U discloses an optical lens coating apparatus, including a coating machine. A rotating frame is fixedly connected to the upper end of the coating machine, and a tray is fixedly connected to the lower end of the rotating frame. A coating frame is placed on the tray, and a handle assembly is fixedly connected to the upper end of the coating frame. The handle assembly includes a fixed seat fixed at the middle of the upper end of the coating frame, a connecting seat fixedly connected to the upper end of the fixed seat, a bearing fixedly connected inside the connecting seat, and a connecting member fixedly connected to the bearing. A sliding groove is formed on the connecting seat, and the connecting member is slidably disposed within the sliding groove. This novel design is applied to an optical lens coating apparatus. By incorporating a handle assembly, the handle can accommodate more users, preventing inconvenience in handling the coating frame due to its large radius. The handle facilitates user handling, and the auxiliary component prevents the user's hands from touching the coated lens.

[0004] However, in the above technical solutions, only by setting up handle components to accommodate different users for easy handling, the coating rack still has a large volume and weight. When the diameter of the coating rack is large and the staff's arm span is small, it is not possible to handle it in a more labor-saving way. Utility Model Content

[0020] Example 1, as Figures 1-5 As shown, the present invention proposes an optical lens coating machine, which includes a coating machine body 1, a rotating frame 2, a tray 3, a coating frame 4, and a fixing assembly. The coating machine body 1 is rotatably connected to the rotating frame 2 via bearings, and the tray 3 is connected to the rotating frame 2. The coating frame 4 is placed on the tray 3.

[0021] In an optional embodiment, the coating frame 4 consists of a base 5, an arc plate 6, a lens holder 7, and a connecting plate 8; the base 5 is placed on the tray 3, and the center of the base 5 is the same as that of the tray 3. Multiple arc plates 6 are distributed thereon, and their two ends are detachably connected to the connecting plate 8 and the base 5 respectively. The lens holder 7 is placed on two adjacent arc plates 6.

[0022] In an optional embodiment, dovetail blocks 10 are connected to both ends of the curved plate 6, and dovetail grooves 11 that cooperate with the dovetail blocks 10 are provided on the connecting plate 8 and the base 5. The curved plate 6 can be disassembled by the dovetail blocks 10 cooperating with the dovetail grooves 11 to accommodate lenses of different sizes, so that it can be disassembled when placing lenses with larger diameters to prevent the curved plate 6 from causing obstruction.

[0023] A fixing component is connected to the coating holder 4. When the fixing component is in use, the moving end of the fixing component moves vertically, and the moving end cooperates with the coating holder 4 to restrict the movement of the coating holder 4.

[0024] In an optional embodiment, each of the curved plates 6 is connected to an auxiliary plate 9, which is located in the middle of the curved plate 6. Lens holders 7 are placed on both sides of the auxiliary plate 9. The two auxiliary plates 9, together with the curved plate 6, form a frame that is fan-shaped when viewed from above. When the lens holder 7 is placed, its position is restricted by the frame to prevent the curved plate 6 from obstructing the lens placed on the lens holder 7 due to placement deviation.

[0025] Example 2, as Figures 2-5 As shown, this utility model proposes an optical lens coating machine. Compared with Embodiment 1, this embodiment describes the detailed structure of the fixing component. The fixing component includes a threaded rod 12, an adjusting handle 13, a moving plate 14, a moving sleeve 15, a guide rod 16, a limiting block 17, and a limiting component. The threaded rod 12 is rotatably connected to the connecting plate 8 by a bearing. The adjusting handle 13 is connected to the end of the threaded rod 12 away from the connecting plate 8. The moving plate 14 is connected to the threaded rod 12, and a threaded connection is made to the threaded rod 12 on the moving plate 14. The movable sleeve 15 has multiple guide rods 16 distributed around the central axis of the threaded rod 12. The guide rods 16 are connected to the connecting plate 8. The movable plate 14 has through holes through which the guide rods 16 pass. The number of limiting blocks 17 corresponds to the lens frame 7. The limiting blocks 17 fit the shape of the lens frame 7. The limiting blocks 17 are connected to the lower end surface of the movable plate 14, i.e., the movable end. The limiting component is connected to the movable plate. When the limiting component is in use, the movable end of the limiting component moves vertically to fit the adjusting handle 13 and restrict its rotation.

[0026] The limiting assembly includes a fixed cylinder 18, a movable cylinder 19, a limiting ring 21, and a limiting rod 22. The fixed cylinder 18 is rotatably connected to the movable plate 14 by a bearing. The fixed cylinder 18 has a threaded hole. The movable cylinder 19 is arranged parallel to the fixed cylinder 18. A screw 20 that mates with the threaded hole is connected to the movable cylinder 19. The limiting ring 21 is sleeved on the outside of the threaded rod 12 and is connected to the movable cylinder 19. Multiple limiting rods 22 are distributed around the central axis of the limiting ring 21. The limiting rods 22 are connected to the limiting ring 21 and mate with the limiting holes on the adjusting handle 13.

[0027] In an optional embodiment, each lens holder 7 is equipped with a handle 23; the handle 23 facilitates the handling of the individual lens holders 7.

[0028] In summary, when using this utility model, the worker places the coating frame 4 (without the lens holder 7) on the tray 3, and then places the lens holder 7 (with the optical lens) on the curved plate 6. The movement of the lens holder 7 is restricted by the auxiliary plate 9. The lens holder 7 is installed in different positions by rotating the coating frame 4 and the tray 3. Then, by rotating the adjusting handle 13, the threaded rod 12 is rotated, and the moving sleeve 15 moves along the vertical direction of the threaded rod 12. The moving sleeve 15 drives the moving plate 14 to press down, so that the limiting block 17 cooperates with the connecting plate 8 to squeeze the lens holder 7 and restrict its position. Then, the fixing cylinder 18 is rotated, and the screw 20 on the fixing cylinder 18 rotates. The screw 20 rotates and engages with the threaded rod. The hole fits together to allow the moving cylinder 19 to move vertically along the central axis of the screw 20. The limiting ring 21 and limiting rod 22 on the moving cylinder 19 move along the threaded rod 12. The limiting rod 22 gradually inserts into the limiting hole opened on the adjusting handle 13, thereby limiting the rotation of the adjusting handle 13. Then the sealing door on the coating machine body 1 is closed to carry out normal coating operation. After the coating operation is completed, rotating the adjusting handle 13 again can move the moving plate 14 and the limiting block 17 away from the lens holder 7. The lens holder 7 can be removed separately by the handle 23, or it can be removed directly by the handle 23 on the coating frame 4 and the adjusting handle 13 of the lens holder 7 without rotating the adjusting handle 13.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
