[0002] Lens fogging is a common phenomenon, especially in winter when people wearing myopia glasses enter a warm room from the cold outside, or when eating hot pot, the lenses encounter moisture, or when wearing a mask, the exhaled gas causes the lenses to fog. Lens fogging brings many inconveniences to people's lives and travel. Therefore, factories will coat the lenses with anti-fog films when producing lenses, but the anti-fog effect of the anti-fog film needs to be tested before leaving the factory to ensure that the anti-fog effect of the lenses meets the standards. At present, when testing the lenses coated with anti-fog films, the lenses coated with anti-fog films are manually cooled down and then sprayed with steam to observe whether they are fogged. Pure manual operation is inefficient and difficult to meet the needs of rapid testing of large batches of lenses under mass production conditions.

DETAILED DESCRIPTION

[0062] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0063] Example 1

[0064] A device for detecting the anti-fog effect of a lens coated with an anti-fog film, such as Figure 1-6 As shown, it includes a main frame 1, a detector 2, an atomizing mechanism 3, an atomizer 31, a servo motor 32, a missing gear 33, a spur gear 34, a rotating frame 35, a fixing mechanism 4, a connecting plate 41, a first fixing rod 42 and a first linear spring 43. The detector 2 is connected to the left side of the main frame 1, and the atomizing mechanism 3 is connected inside the main frame 1. The atomizing mechanism 3 is used to spray the lens. The fixing mechanism 4 is connected to the atomizing mechanism 3. The fixing mechanism 4 is used to clamp the lens. The atomizer 31 is connected to the upper part of the main frame 1. The atomizer 31 is used to spray the lens. The servo motor 32 is connected to the lower rear side of the main frame 1 through the motor frame. The output of the servo motor 32 A missing gear 33 is connected to the rear side of the shaft through a key, and a rotating frame 35 is rotatably connected to the middle of the main frame 1. The middle part of the rotating frame 35 is cross-shaped, and a spur gear 34 is connected to the rear side of the rotating frame 35 through a key. The spur gear 34 intermittently meshes with the missing gear 33. Connecting plates 41 are welded on the four sides of the middle part of the rotating frame 35, and two first fixing rods 42 are slidably connected to the outer sides of the four connecting plates 41. The first fixing rods 42 are used to clamp the lens. The inner sides of the two first fixing rods 42 are made of rubber. The middle parts of the eight first fixing rods 42 are all covered with first linear springs 43, and the two ends of the first linear springs 43 are respectively connected to the first fixing rods 42 and the connecting plates 41.

[0065] When in use, the first fixing rod 42 on the right is pulled outward, at which time the first linear spring 43 is compressed, and then the lens to be tested is clamped between the first fixing rod 42 on the right, and the first fixing rod 42 is released. At this time, the first linear spring 43 is reset, driving the first fixing rod 42 to move inward to clamp the lens. Since the inner side of the first fixing rod 42 is made of rubber, the lens will not be damaged when clamping the lens. Then the servo motor 32 is started, and the atomizer 31 is started at the same time, and the atomizer 31 is controlled to spray mist every three seconds. The output shaft of the servo motor 32 drives the missing gear 33 to rotate. When the missing gear 33 rotates to mesh with the spur gear 34, it drives the rotating frame 35 to rotate, thereby driving the connecting plate 41, the first fixing rod 42 and the lens to rotate. When the lens rotates to the bottom of the atomizer 31 At this time, the missing gear 33 just disengages from the spur gear 34, and the atomizer 31 just sprays mist to the lens, causing the lens to fog quickly. Then the missing gear 33 meshes with the spur gear 34 again, driving the rotating frame 35 to rotate, and then driving the fogged lens to rotate to the detector 2. The missing gear 33 disengages from the spur gear 34 again, allowing the detector 2 to detect the visibility of the lens. If the visibility is high, it means that the anti-fog effect of the anti-fog film plated on the lens is good. Otherwise, it means that the anti-fog effect is poor. Then repeat the above operation, drive the tested lens to the bottom of the main frame 1, and then the staff can manually take out the tested lens. After the detection is completed, turn off the servo motor 32 and the atomizer 31. In this way, the lens can be continuously tested with high detection efficiency.

[0066] Example 2

[0067] On the basis of Example 1, Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9As shown, it also includes a clamping mechanism 5, which is used to automatically load the lenses. The clamping mechanism 5 includes a loading frame 51, a push rod 52, a second fixed rod 53, a screw rod 54, a rotating rod 55, a second linear spring 56, a first slide rod 57 and a slide rail 58. A loading frame 51 is welded on the right side of the main frame 1. The loading frame 51 is used to store lenses. The bottom of the loading frame 51 is inclined, and the lower left side of the loading frame 51 is arc-shaped. Push rods 52 are welded on the upper, lower, left and right sides of the middle of the rotating frame 35. The push rods 52 are located on the inner side of the connecting plate 41. Two second fixed rods 53 are slidably connected to the lower left side of the loading frame 51. The second fixed rods 53 are used to position the lenses. The two first fixed rods 53 are used to position the lenses. The inner sides of the two fixed rods 53 are made of rubber, and the middle parts of the two second fixed rods 53 are sleeved with second linear springs 56, and the two ends of the second linear springs 56 are respectively connected to the second fixed rods 53 and the loading frame 51, and the outer sides of the two second fixed rods 53 are welded with screw rods 54, and the two screw rods 54 are threadedly connected with rotating rods 55. After the push rod 52 moves, it contacts the rotating rod 55 to drive the rotating rod 55 to rotate, and the first sliding rod 57 is welded to the inner side of the upper part of the two rotating rods 55. Slide rails 58 are welded on the front and rear sides of the lower left part of the loading frame 51, and the first sliding rod 57 on the front side is slidably connected to the slide rail 58 on the front side, and the first sliding rod 57 on the rear side is slidably connected to the slide rail 58 on the rear side. First, put the lens to be tested into the loading frame 51. Since the bottom of the loading frame 51 is inclined, the lens on the lower side rolls along the slope to the lower left side of the loading frame 51. The lower left side of the loading frame 51 is arc-shaped, which can limit the lens and will not limit the lens inside the loading frame 51, which is convenient for the first fixed rod 42 to clamp. When the rotating frame 35 rotates, it drives the push rod 52 to rotate. When the push rod 52 rotates to contact the rotating rod 55, it drives the rotating rod 55 to rotate, thereby driving the first sliding rod 57 to slide along the sliding rail 58. The rotating rod 55 drives the screw rod 54 to move inward, thereby driving the second fixed rod 53 to move inward. At this time, the second linear spring 56 is compressed, so that the second fixed rod 53 clamps the middle part of the lens. Since the inner side of the second fixed rod 53 is made of rubber, The rod 53 will not damage the lens. The second fixing rod 53 clamps and positions the lens to prevent the lens from being pushed to the right when the first fixing rod 42 clamps the lens. In this way, the first fixing rod 42 can clamp the lens. When the push rod 52 rotates upward to separate from the rotating rod 55, the second linear spring 56 is reset, driving the second fixing rod 53 and the screw rod 54 to move outward and reset, thereby driving the rotating rod 55 to reverse and reset. The rotating rod 55 drives the first sliding rod 57 to move in the opposite direction and reset, so that the second fixing rod 53 releases the lens. At this time, the first fixing rod 42 has clamped the lens firmly and will not loosen easily, which is convenient for the first fixing rod 42 to drive the lens to move out of the loading frame 51. In this way, automatic loading can be achieved without manual loading, which can reduce the trouble of operation and improve work efficiency.

[0068] like Figure 1 , Figure 2 , Fig.10 and Fig.11 As shown, it also includes a disengagement mechanism 6, which is used to assist the lens in disengaging from the first fixed rod 42. The disengagement mechanism 6 includes a blanking frame 61, a fixed column 62, a third fixed rod 63 and a third linear spring 64. A blanking frame 61 is welded to the bottom of the main frame 1, and the blanking frame 61 is used to guide the lens for receiving materials. The blanking frame 61 is tilted, and two fixed columns 62 are welded to the upper right side of the blanking frame 61. The upper parts of the two fixed columns 62 are both slidably connected to the third fixed rod 63. The upper parts of the two third fixed rods 63 are both sleeved with a third linear spring 64, and the two ends of the third linear spring 64 are respectively connected to the upper part of the fixed column 62 and the middle part of the third fixed rod 63. When the inspected lens rotates to contact the right side of the inner wall of the blanking frame 61, the blanking frame 61 limits the inspected lens to facilitate the inspected lens to be separated from the first fixing rod 42. At the same time, the third fixing rod 63 is manually pressed inward. At this time, the third linear spring 64 is stretched, so that the third fixing rod 63 limits the lens to prevent the inspected lens from rotating under the limit of the blanking frame 61 and being unable to be separated from the first fixing rod 42, causing the inspected lens to continue to rotate with the first fixing rod 42. When the inspected lens is separated from the first fixing rod 42, the third fixing rod 63 is released. At this time, the third linear spring 64 is reset, driving the third fixing rod 63 to move outward and reset. Since the blanking frame 61 is tilted, the inspected lens will roll to the left side of the blanking frame 61, which is convenient for the staff to take out the inspected lens.

[0069] like Figure 1 , Fig.12 and Fig.13As shown, it also includes a limiting mechanism 7, which is used to drive the third fixed rod 63 to move inward. The limiting mechanism 7 includes a first wedge block 71, a second wedge block 72, a guide rod 73, a fourth linear spring 74 and a sliding rod 75. The front and rear sides of the four connecting plates 41 are welded with the first wedge block 71, the front and rear sides of the right part of the blanking frame 61 are welded with the guide rod 73, the guide rod 73 is located on the lower right side of the fixed column 62, the two guide rods 73 are slidably connected with the sliding rod 75, the middle parts of the two guide rods 73 are sleeved with the fourth linear spring 74, the two ends of the fourth linear spring 74 are respectively connected to the bottom of the sliding rod 75 and the lower part of the guide rod 73, the tops of the two sliding rods 75 are welded with the second wedge block 72, the first wedge block 71 contacts with the second wedge block 72 after moving, and the second wedge block 72 contacts with the third fixed rod 63. When the first wedge block 71 is rotated to separate from the second wedge block 72, the fourth linear spring 74 is reset, driving the second wedge block 72 and the sliding rod 75 to move upward and reset, so that the second wedge block 72 is separated from the third fixing rod 63, and the third fixing rod 63 moves outward and resets under the action of the third linear spring 64.

[0070] like Figure 1 , Figure 2 , Fig.14 and Fig.15 As shown, a buffer mechanism 8 is also included, and the buffer mechanism 8 is used to buffer the lenses that have been tested. The buffer mechanism 8 includes a buffer plate 81, a second slide bar 82 and a fifth linear spring 83. The buffer plate 81 is slidably connected to the left side of the blanking frame 61. The buffer plate 81 is used to remove the rolling impact of the lenses that have been tested. The left side of the blanking frame 61 is slidably connected to the second slide bar 82. The right side of the second slide bar 82 is welded to the left side of the buffer plate 81. The middle part of the second slide bar 82 is sleeved with a fifth linear spring 83, and the two ends of the fifth linear spring 83 are respectively connected to the second slide bar 82 and the blanking frame 61. After the inspected lens falls into the blanking frame 61, it rolls to the left along the blanking frame 61 until it contacts the buffer plate 81, and the fifth linear spring 83 is adaptively deformed here. Under the action of the fifth linear spring 83, the buffer plate 81 removes the rolling impact of the inspected lens to avoid the inspected lens colliding with the blanking frame 61, thereby causing damage to the lens. Then the staff can take out the inspected lens.

[0071] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
