Description

Technical Field

[0001] The utility model relates to the field of coating for sun visor lenses, in particular to a magnetron sputtering coating device suitable for automobile sun visor lenses. Background Art

[0002] An automobile sun visor is an important component inside an automobile, and it is usually installed above the heads of the driver and the front passenger. Its main function is to block the sunlight from the roof, so as to reduce the influence of direct sunlight on the sight lines of the driver and passengers, and at the same time reduce the temperature inside the vehicle, improving the driving comfort and safety. Automobile sun visors are usually made of lightweight materials such as plastics or fabrics for easy folding and storage. And the automobile sun visor lens, as a part of the sun visor, is embedded in the sun visor body.

[0003] When a car accident occurs, it may cause the automobile sun visor lens to break. To prevent the fragments of the automobile sun visor lens from causing secondary injuries to the vehicle occupants, it is necessary to coat the automobile sun visor lens. For this purpose, a magnetron sputtering coating device suitable for automobile sun visor lenses is required.

[0004] The current magnetron sputtering coating device for automobile sun visor lenses usually directly places or clamps the lens above the excitation target. Usually, in order to fix the lens, the bottom of the lens is blocked, resulting in some areas at the bottom of the lens being unable to be coated, and the lens needs to be trimmed later, with a rather troublesome process and inconvenient use. On the other hand, the current magnetron sputtering coating device usually needs to use an observation window to observe the color of the plasma excitation inside the vacuum chamber to judge the excitation state of the plasma, so as to adjust the input voltage. However, the plasma inside the vacuum chamber will also cover the observation window after deflection. After long-term use, the observation window will also be coated and unable to clearly observe the internal situation, and special chemical reagents or polishing are required to clean it, which is rather troublesome. Therefore, a magnetron sputtering coating device suitable for automobile sun visor lenses is proposed to solve the above problems. Summary of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present invention: A magnetron sputtering coating device suitable for automotive sun visor lenses, including a vacuum tank 1. The vacuum tank 1 can form a vacuum state inside through a vacuum pump. A high-voltage anode rod 2 is provided at the top of the vacuum tank 1. A magnetron ion exciter 3 is provided on the inner wall of the bottom end of the vacuum tank 1. The magnetron ion exciter 3 includes a magnetron deflector 21. A strong magnetic field is provided inside the magnetron deflector 21, which can deflect the excited plasma target. The bottom of the magnetron deflector 21 is provided on the inner wall of the bottom end of the vacuum tank 1. A high-voltage cathode block 22 is provided at the top of the magnetron deflector 21. An excitation target 23 is placed on the top of the high-voltage cathode block 22. After the high-voltage anode rod 2 and the high-voltage cathode block 22 are energized, a huge voltage difference will be generated between them. The high voltage will turn the excitation target 23 into a plasma state, and through magnetic field deflection, it will combine with the lens to form a coating. A protective cover 24 for protecting internal components is detachably connected to the outer periphery of the magnetron deflector 21. The outer peripheries of the high-voltage cathode block 22 and the excitation target 23 are both slidably connected to the inside of the protective cover 24. A fixed base 4 for fixing connection is slidably connected to the outer periphery of the magnetron ion exciter 3. The outer periphery of the protective cover 24 is slidably connected to the inside of the fixed base 4. The bottom of the fixed base 4 is fixedly connected to the inner wall of the bottom end of the vacuum tank 1.

[0033] Refer to Figures 1 - 3, a sliding groove 5 is formed inside the fixed base 4. There are two groups of sliding grooves 5, which are symmetrically arranged front and back inside the fixed base 4. A slider 6 is slidably connected inside the sliding groove 5. The sliding groove 5 restricts the slider 6 to slide only back and forth along the inner wall of the sliding groove 5. A clamping plate 7 for fixed connection is fixedly connected to the top of the slider 6. A rack 8 is fixedly connected to the inner side of the clamping plate 7. There are two groups of racks 8, which are symmetrically arranged left and right on the left and right sides of the clamping plate 7. The rack 8 on the front clamping plate 7 and the rack 8 on the rear clamping plate 7 are centrosymmetric. A rotating bracket 9 for fixed connection is fixedly connected to the side of the fixed base 4. A rotating gear 10 is rotatably connected inside the rotating bracket 9. The inner side of the rack 8 meshes with the outer circumference of the rotating gear 10. When the rotating gear 10 rotates, it can drive the racks 8 on the upper and lower sides to move, and the amount of movement is the same. A threaded bracket 11 for fixed connection is fixedly connected to the bottom of the fixed base 4. A threaded column 12 is threadedly connected inside the threaded bracket 11. When the threaded column 12 is rotated, the threaded column 12 can move back and forth along the inner wall of the threaded bracket 11. The inner side of the threaded column 12 is rotatably connected to the outside of the slider 6. A clamping block 13 is hinged to the bottom of the clamping plate 7. The clamping block 13 is V-shaped, and several groups of grooves are formed inside, so as to increase the friction force.

[0034] Refer to Figure 1 and Figure 5 , an observation window 14 for conveniently observing the internal situation is detachably connected to the right side of the vacuum tank 1. A limiting groove 15 is formed inside the observation window 14. There are two groups of limiting grooves 15, which are symmetrically arranged front and back. A threaded rod 16 is rotatably connected inside the limiting groove 15. A clamping piece 17 is threadedly connected to the outer circumference of the threaded rod 16. The outer circumference of the clamping piece 17 is slidably connected inside the limiting groove 15. When the threaded rod 16 is rotated, the threaded rod 16 can drive the clamping piece 17 to slide left and right along the limiting groove 15. A transparent patch 18 is contacted on the right side of the clamping piece 17. An observation glass 19 is adhered to the right side of the transparent patch 18 and can be easily torn off. A sealing ring 20 for ensuring the airtightness inside the vacuum tank 1 is contacted on the right side of the observation glass 19. The outer circumferences of the transparent patch 18, the observation glass 19 and the sealing ring 20 are all slidably connected inside the observation window 14.

[0035] Working principle: When it is desired to conveniently hold the lens, place the lens between the two clamping plates 7. Rotate the threaded column 12, and the threaded column 12 drives the front clamping plate 7 to move backward. The front clamping plate 7 drives the two front sets of racks 8 to move backward. The front rack 8 drives the rotating gear 10 to rotate. The rotating gear 10 drives the two rear sets of racks 8 to move forward, driving the rear clamping plate 7 to move forward, thereby driving the two clamping plates 7 to move towards the center. When the inner wall of the clamping block 13 near the inside contacts the front and rear sides of the lens, the lens will block the inner wall of the clamping block 13 near the inside from continuing to move forward, driving the clamping block 13 to rotate inward, so that the outer wall of the clamping block 13 near the outside contacts the left and right sides of the lens. Continue to rotate the threaded column 12 to clamp the lens tightly from multiple directions, and at the same time, it will not block the bottom coating area, which is relatively convenient to use. When it is desired to conveniently clean the observation glass 19, rotate the threaded rod 16, and the threaded rod 16 drives the clamping piece 17 to move outward. The clamping piece 17 is separated from the transparent patch 18. At this time, the observation glass 19 can be removed, the transparent patch 18 can be torn off, and a new transparent patch 18 can be reattached, so that the coating on the observation glass 19 can be conveniently cleaned without using a special cleaning agent or polishing the glass.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
