Description

Technical Field

[0001] The utility model relates to the technical field of lens detection, and more specifically, to an eccentric detection device for optical lenses. Background Art

[0002] Lenses can be used to correct the vision of users and obtain a clear field of view. During the processing of lenses, it is necessary to measure the eccentric distance of the lenses. The so-called measurement of the eccentric distance of the lenses refers to placing the lenses on a jig and performing multi-angle inspection and comparison through an electron microscope.

[0003] Existing mechanisms cannot effectively limit the position of the lenses during the detection process, resulting in poor detection results. At the same time, it is not convenient to adjust the height of the detection head, and it cannot meet more requirements in actual use, so the practicability needs to be improved.

[0004] After retrieval, a Chinese patent with the authorization announcement number CN213068137U discloses a medical optical lens eccentric detection device. Through the cooperation between a rotating assembly, a partition plate, a first pulley and a clamping assembly, etc., effective limiting of the lenses is achieved. At the same time, the lenses can be flipped during the detection process to obtain multi-faceted detection data, ensuring the detection effect. Moreover, it is convenient to fix lenses of different sizes, and the product has a better experience and higher practicability. At the same time, the height of the detection head can be quickly adjusted, and then the distance between the detection head and the lenses can be adjusted according to needs to obtain accurate detection results, meeting more requirements in actual use and having stronger applicability.

[0005] However, when this structure is actually used, the lens is placed between two arc-shaped clamping blocks, and effective clamping of the lens is achieved through the cooperation of the central axis and the spring. This structure can only fix lenses with a diameter smaller than the diameter of the lens in the relaxed state between the arc-shaped clamping blocks, resulting in unstable fixation of smaller lenses and thus affecting the use effect.

The U-shaped slider 6 is slidably connected to the sliding groove 7. A connecting rod 8 is arranged inside the U-shaped slider 6, and a roller 9 is sleeved on the connecting rod 8. Starting the first electric telescopic rod 5 drives the second clamping arc plate 3 to slowly approach the lens, thereby driving the U-shaped slider 6 to move in the sliding groove 7, so that the roller 9 at its bottom rolls on the connecting rod 8, thereby reducing the friction effect of the U-shaped slider 6 inside the sliding groove 7, thereby improving the use effect. Until the second clamping arc plate 3 and the first clamping arc plate 2 clamp the lens, so as to fix the lens, reducing the deviation of the lens during the detection process. At the same time, soft silicone layers 4 are arranged on the surfaces of the first clamping arc plate 2 and the second clamping arc plate 3, so as to prevent the clamping work from causing wear to the lens surface.

[0029] Referring to Figures 2-3 as shown, a cavity is formed inside the workbench 1, and a second electric telescopic rod 10 is arranged inside the cavity. The top of the second electric telescopic rod 10 is fixedly connected with a top plate 11. Starting the first electric telescopic rod 5 drives the second clamping arc plate 3 to move away from the lens, thereby loosening the lens. Then starting the second electric telescopic rod 10 drives the top plate 11 to move upward, thereby ejecting the lens, which is more convenient for taking, and has higher practicability.

[0030] Referring to Figures 3-4As shown in the figure, a support frame 12 is provided on the top of the workbench 1. An adjustment mechanism is provided on one side of the support frame 12.

At the same time, the guiding strip 19 on one side of the fixing plate 17 also moves in the guiding groove opened on the surface of the support frame 12, so as to ensure the stability of the fixing plate 17 during the movement. Then the fixing plate 17 also drives the telescopic sight 18 to move, so as to quickly adjust the height. The distance between the telescopic sight 18 and the lens can be adjusted according to the actual situation to obtain accurate detection results.

[0031] Referring to Figures 4-5 As shown in the figure, two guiding grooves are opened on the surface of the support frame 12.

[0032] The working principle of the present utility model:

[0033] The present utility model is an optical lens eccentricity detection device. When the device is in use, first place the lens in the installation groove on one side of the first clamping arc plate 2, and then start the first electric telescopic rod 5 to drive the second clamping arc plate 3 to slowly approach the lens, thereby driving the U-shaped slider 6 to move in the chute 7, so that the roller 9 at its bottom rolls on the connecting rod 8, thereby reducing the friction effect of the U-shaped slider 6 inside the chute 7, thus improving the use effect. Until the second clamping arc plate 3 and the first clamping arc plate 2 clamp the lens, so as to fix the lens, reducing the offset of the lens during the detection process. At the same time, soft silicone layers 4 are provided on the surfaces of the first clamping arc plate 2 and the second clamping arc plate 3, so as to prevent the clamping operation from causing wear to the surface of the lens;

[0034] Then, start the motor 13 to drive the threaded rod 14 to rotate, thereby driving the threaded barrel 15 to move up and down on the surface of the threaded rod 14. The threaded barrel 15 drives the slider 16 and the fixing plate 17 to move. At the same time, the guiding strip 19 on one side of the fixing plate 17 also moves in the guiding groove opened on the surface of the support frame 12, so as to ensure the stability of the fixing plate 17 during the movement. Then, the fixing plate 17 also drives the telescopic sight 18 to move, so as to quickly adjust the height. The distance between the telescopic sight 18 and the lens can be adjusted according to the actual situation to obtain accurate detection results;

[0035] The light emitted by the light source 21 passes through the reflection seat 21 and the telescopic sight 18 in sequence and then shines on the lens. The lens reflects the light. The reflected light passes through the telescopic sight 18 and the reflection seat 21 in sequence and then enters the lens in the external camera assembly and is received by the CCD 510, so that the detection result can be directly displayed, making the operation convenient and fast. After the detection is completed, start the first electric telescopic rod 5 to drive the second clamping arc plate 3 to move away from the lens, thereby loosening the lens. Then, start the second electric telescopic rod 10 to drive the top plate 11 to move upward, thereby ejecting the lens, which is more convenient for taking, and has higher practicability.

[0036] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
