Description

Technical Field

[0001] The present invention relates to the technical field of weather resistance detection, and in particular to a weather resistance test system for optical lenses. Background Art

[0002] Optical lenses are usually used to observe different worlds, so they must have some functions to see different worlds. To this end, different chemicals are evaporated onto the lenses to enable the lenses to transmit light in different bands. Some lenses usually require multiple functions or special requirements. These special requirements usually require two or more lenses to be bonded together. Light will reflect, and the edges of curved lenses usually reflect a certain amount of light. To avoid this, ink is often applied to the edges of the lenses to reduce internal reflections and stray light. Weather resistance is a necessary testing step to explore the performance of optical lenses. If optical lenses are not stored properly, bacterial erosion of the surface coating will occur, seriously affecting the use of the optical lenses. Current weather resistance testing usually targets the entire optical lens without detailed differentiation of its various parts. The erosion conditions of the coatings in different parts are different corresponding to different details. If the test is not differentiated, it is easy to cause interference between the coating and bacteria, which makes the final weather resistance test results inaccurate on the effects of different coating levels. Based on this, an optical lens weather resistance test system is proposed. Summary of the Invention

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.

[0029] Example, see Figures 1 to 7 An optical lens weather resistance test system includes a test bench, which consists of an upper movable platform 1 and a lower fixed base 2. The upper movable platform 1 and the lower fixed base 2 are connected by a lifting control device. Furthermore, the lifting control device includes a support frame 10 fixedly arranged on the side wall of the lower fixed base 2, and a lifting cylinder 11 is provided on the support frame 10. The output end of the lifting cylinder 11 is fixedly connected to the top of the upper movable platform 1.

[0030] During the weather resistance test stage of the optical lens, the upper movable platform 1 is controlled to move downward by the lifting control device, so that the upper movable platform 1 and the lower fixed seat 2 are in a close state. At this time, both sides of the optical lens are in close contact with the optical lens test units arranged on the upper movable platform 1 and the lower fixed seat 2, thereby ensuring that during the bacterial erosion test, external factors are avoided from interfering with bacterial erosion.

[0031] The push rods involved in this solution are all electric push rods with direct-drive elements, which are existing technologies and will not be described in detail here.

[0032] Both the upper movable platform 1 and the lower fixed base 2 are provided with multiple optical lens test units, which are devices for testing optical lenses. The upper movable platform 1 is provided with multiple storage lifting push rods 3, and the output end of the storage lifting push rod 3 is connected to the storage inner ring 4, which is connected to the storage outer ring 5 through a connecting rod. The storage outer ring 5 and the storage inner ring 4 are provided with storage clamps that cooperate with each other to achieve positioning and clamping of the optical lens; further, the storage clamp includes a fixed clamping half ring 12 fixedly connected to the inner side wall of the storage outer ring 5, and the storage inner ring 4 is provided with multiple telescopic openings, and the inner wall of the telescopic opening is provided with a magnetic repulsion seat 13, and the inner wall of the telescopic opening is slidably provided with a magnetic disk 14, and the magnetic disk 14 is connected to the magnetic repulsion seat 13 through a reset spring to achieve a reset effect on the magnetic disk 14, and the magnetic disk 14 is connected to a movable clamping half ring 15 through a clamping column.

[0033] It should be noted that the magnetic force of the magnetic disk 14 repels the magnetic force of the magnetic repulsion seat 13. The magnetic repulsion seat 13 is an electromagnet. When powered on, it can control the movable clamping half ring 15 to move forward, thereby supporting the optical lens under test between the movable clamping half ring 15 and the fixed clamping half ring 12, ensuring that it is between the two optical lens test units, and achieving a positioning effect.

[0034] The optical lens test unit includes a test rotating sleeve 6 rotatably arranged in the upper movable platform 1 and the lower fixed seat 2. The upper movable platform 1 and the lower fixed seat 2 are both provided with a torque driving component for controlling the rotation of the test rotating sleeve 6. Furthermore, the torque driving component includes a fixed gear ring 16 fixedly arranged on the outer wall of the test rotating sleeve 6. A transmission cavity is opened in the upper movable platform 1 and the lower fixed seat 2. The bottom of the test rotating sleeve 6 is in the transmission cavity, that is, the fixed gear ring 16 installed on the outer wall of the test rotating sleeve 6 is in the transmission cavity, which can ensure the meshing transmission with the driving gear ring 19.

[0035] A torque drive motor 17 is provided on both the upper movable platform 1 and the lower fixed base 2. The output end of the torque drive motor 17 is connected to the drive gear 18 through a torque measuring part. The torque measuring part is a prior art and will not be described here. The inner side wall of the transmission cavity is rotatably connected to a drive gear ring 19. The drive gear ring 19 is rotatably connected to the inner wall of the transmission cavity through an external bearing. The drive gear ring 19 is meshed with the drive gear 18 and the fixed gear ring 16.

[0036] The interior of the test rotating sleeve 6 is connected to an outer ring body 7 through a connecting block. A resistance heating element is provided inside the outer ring body 7 for heating the optical lens. The inner wall of the outer ring body 7 is connected to an isolation cover ring body 8 through an inner spacer block. An adsorption fastening component is provided inside the isolation cover ring body 8.

[0037] Among them, the inner diameter of the outer sleeve 7 is adapted to the diameter of the optical lens. During the test, it can be used to fit the optical lens and to contact the adhesive parts of the multi-layer or double-layer optical lens. When the adhesive parts of the optical lens need to be heated, the heating effect can be ensured by the resistance heating element arranged in the outer sleeve 7. Heat transfer is achieved through the outer sleeve 7 to ensure heating of the adhesive parts to meet the needs of the test.

[0038] It is worth noting that in this solution, the function of the isolation cover ring 8 is to isolate the connection parts of the two coatings according to the different coatings on the surface of the optical lens through an isolation cover ring 8. When N coatings need to be distinguished, N-1 isolation cover rings 8 can be set accordingly.

[0039] The advantage of adopting the above structure is that it physically isolates adjacent test areas and cooperates with the vacuum function of the adsorption fastening components (electric push rod 23, push ring 24, fan-shaped piston 25, one-way air port 26) to realize bacterial testing: negative pressure is formed in the isolated area, which effectively prevents cross-contamination of bacteria in different test areas (different coatings or different strains), ensuring the independence and accuracy of the test data.

[0040] Furthermore, the adsorption and fastening assembly includes an electric push rod 23 fixedly arranged at the bottom of the test rotating sleeve 6, and the output end of the electric push rod 23 is connected to a push ring 24, and the push ring 24 is connected to a fan-shaped piston 25 through multiple movable rods passing through the joint control disk 20. A one-way air port 26 is provided on the fan-shaped piston 25, and an air outlet hole connected to the one-way air port 26 is provided on the movable rod.

[0041] The above structure has different advantages in different test modes. In the process of conducting a bacterial test, after the isolation cover ring body 8 is in close contact with the surface of the optical lens, the fan-shaped piston 25 can be controlled to move closer to the optical lens in the isolation cover ring body 8 to achieve exhaust through the one-way air port 26, and when it is away from the optical lens, the optical lens in the area of ​​the isolation cover ring body 8 is vacuumed to avoid bacterial growth and mutual interference between bacteria in the test areas of two adjacent coatings, thereby ensuring that isolation is achieved.

[0042] When the weather resistance test is carried out on the adhesive parts of double-layer or multi-layer optical lenses, the fan-shaped piston 25 can be used to draw a vacuum in the isolation cover ring body 8 to ensure that the isolation cover ring body 8 is firmly adsorbed on the optical lens, so as to ensure that the optical lens in the upper movable platform 1 and the lower fixed seat 2 can achieve reverse rotation, thereby driving the optical lens to twist and generating a torsional resistance force on the adhesive parts (which can be obtained through a torque measuring device set at the output end of the torque drive motor 17) to determine whether the weather resistance of the adhesive parts meets the standards.

[0043] A push-supply push rod 9 is provided inside the test rotating sleeve 6, and the output end of the push-supply push rod 9 is connected to the mycelium combination disk. The output end of the push-supply push rod 9 is fixedly connected to the joint control disk 20. The mycelium combination disk includes a bacterial erosion supply disk 22 and multiple mycelium test disks 21. The joint control disk 20 is respectively connected to the bacterial erosion supply disk 22 and the mycelium test disk 21 through pillars.

[0044] At the beginning of the experiment, the bacterial mycelium that needs to be explored can be cultured in a culture dish and transferred to the mycelium combination plate. During the experiment, the mycelium combination plate is controlled to move upward by pushing the supply push rod 9, close to the surface of the optical lens, thereby accelerating the erosion speed of the mycelium and improving the test efficiency.

[0045] When the present invention performs weather resistance testing on optical lenses and explores the influence of bacteria on the polymer coating of optical lenses, the optical lens to be tested is placed on the fixed clamping half ring 12 and the movable clamping half ring 15 so that it is accurately positioned at the position of the optical lens test unit for subsequent testing;

[0046] During the test, the object lifting push rod 3 is controlled to control the optical lens to move to the test rotating sleeve 6 located on the lower fixed seat 2. At this time, the upper movable platform 1 is controlled to move downward by the lifting cylinder 11, so that the test rotating sleeve 6 located above moves downward, and in the process of moving, the clamping force on the optical lens is released by moving the clamping half ring 15. The test rotating sleeve 6 above and below the optical lens will effectively sleeve the optical lens, and the outer ring body 7 will semi-wrap the optical lens. At this time, the electric push rod 23 can be controlled to drive the mycelium test plate 21 and the bacterial erosion supply plate 22 to move upward, so that the mycelium is in contact with the optical lens, and the bacterial resistance and erosion resistance test of the optical lens is carried out. It can also realize regional testing, conduct tests on different bacterial species for different coatings, and avoid interference between bacteria to ensure the accuracy of the test data. This system integrates two key weather resistance test functions: bacterial erosion test and adhesive layer weather resistance (torque test), which greatly improves test efficiency and equipment utilization.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
