Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a large-caliber optical coating machine. Background Art

[0002] Optical coating is to coat a very thin transparent film on the surface of glass. When light enters different transmission materials, about 5% will be reflected. There are many lenses and refractors in optical sights, which can cause a loss of 30% to 40% of the incident light. Modern optical lenses are usually coated with a single or multi-layer anti-reflection film of magnesium fluoride. A single-layer anti-reflection film can reduce reflection to 1.5%, and a multi-layer anti-reflection film can reduce reflection to 0.25%. Therefore, if the entire sight is properly coated, the light penetration rate can reach 95%. In the production of optical lenses, a coating machine is needed to coat the optical lenses.

[0003] Before optical coating, the lenses need to be placed in a rack, and then the rack is hung at the bottom of the coating machine. However, due to the high position of the coating machine, the rack is easily dropped during the hanging process, which may cause the lenses in the rack to be damaged. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 A large-aperture optical coating machine comprises a coating chamber 1, a coating machine body 2 fixed on the inner top wall of the coating chamber 1, and a placement rack 3. An auxiliary structure for hanging the placement rack 3 is provided on the inner side of the coating chamber 1.

[0025] like Figure 1 As shown, the auxiliary structure includes a frame 4 fixed to the left side wall of the coating chamber 1, a threaded rod 5 rotatably connected to the inner top wall of the frame 4, a handle 6 fixed to the bottom end of the threaded rod 5, a threaded block 7 threadedly connected to the outside of the threaded rod 5, a slider 8 fixed to the right side of the threaded block 7, an outer frame 9 fixed to the right side of the slider 8, and a clamping assembly arranged on the inner side of the outer frame 9.

[0026] It should be noted that the bottom end of the threaded rod 5 passes through the inner bottom wall of the frame 4 and extends to the inner side of the center of the handle 6 and is fixedly connected to the handle 6. The length of the threaded block 7 is equal to the distance between the inner left wall and the inner right wall of the frame 4, and the connection relationship between the threaded block 7 and the frame 4 is a sliding connection. A sliding opening is provided on the right side wall of the frame 4, and the slider 8 is slidably connected to the inner side of the sliding opening. A connecting plate 10 is fixedly connected to the right side of the outer frame 9, and a sliding rod 11 is slidably connected to the inner side of the connecting plate 10, and the upper and lower ends of the sliding rod 11 are bent to the right and fixedly connected to the inner right wall of the coating bin 1.

[0027] The clamping assembly includes cavities 12 respectively opened in the left side wall and the right side wall of the outer frame 9, telescopic rods 13 respectively fixed to the left side wall of the left cavity 12 and the right side wall of the right cavity 12, a spring 14 arranged on the outside of the telescopic rod 13, and clamping plates 15 respectively fixed to the opposite ends of the telescopic rods 13 on the left and right sides. The height of the clamping plate 15 is equal to the height of the cavity 12, and the right side wall of the left clamping plate 15 and the left side wall of the right clamping plate 15 are both provided with card slots compatible with the placement rack 3.

[0028] In addition, through the cooperation of the connecting plate 10 and the sliding rod 11, the upward movement of the outer frame 9 is more stable. When the telescopic rod 13 and the spring 14 are used in combination, the elasticity of the spring 14 and the adjustability of the length of the telescopic rod 13 enable it to adapt to objects of various shapes and sizes, thereby improving the clamping stability of the clamping plate 15. The elasticity of the spring 14 can make the clamping plate 15 better adapt to the shape and size of the placement rack 3, and the adjustability of the length of the telescopic rod 13 can further adjust the clamping range of the clamping plate 15 to ensure the clamping stability and reliability of the placement rack 3. In addition, the coordinated use of the telescopic rod 13 and the spring 14 can also improve the stiffness and accuracy of the clamping. Since the telescopic rod 13 and the spring 14 usually have higher stiffness, they can provide a more stable clamping force to ensure the posture stability of the placement rack 3.

[0029] The working principle of the above embodiment is:

[0030] One side of the placement rack 3 is clamped in the slot of the clamping plate 15. The elasticity of the spring 14 allows the clamping plate 15 to better adapt to the shape and size of the placement rack 3, and the length adjustability of the telescopic rod 13 can further adjust the clamping range of the clamping plate 15 to ensure the clamping stability and reliability of the placement rack 3. Then, the handle 6 is turned to drive the threaded rod 5 to rotate, and the threaded rod 5 then generates a threaded thrust to drive the threaded block 7 to move upward, and the threaded block 7 then drives the slider 8 to move upward, and the slider 8 then moves the auction frame 9 upward, driving the placement rack 3 to move upward.
