[0019] The following is combined with Figure 1-4 This application is described in further detail.
[0020] The present application embodiment discloses a high-stability lens eccentricity detection device.

[0021] When the eccentricity of the lens is detected, the lens is placed in the placement groove 2, and then the splicing piece 7 acts on the first body 111 and the second body 112 to approach each other, and the first body 111 and the second body 112 clamp the lens. When the lens is eccentric, when the first body 111 and the second body 112 are close to each other for splicing, the electrical contact plates 3 on both sides cannot be close to each other and fit together, resulting in the detection lamp 4 being unable to be electrically connected to the power supply 5, and the detection lamp 4 cannot be lit; when the lens is not eccentric but is a standard disc, the first body 111 and the second body 112 are spliced to form a completed placement groove 2, the electrical contact plates 3 on both sides are fitted and connected, the power supply 5 is electrically connected to the detection lamp 4 and the detection lamp 4 is lit. In the above process, whether the lens is eccentric is detected by observing whether the detection lamp 4 is lit, and the operation is simple and convenient.

Two first electric push rods 72 are provided, and are respectively located on both sides of the detection platform 1 and symmetrically arranged along the axis of the detection platform 1. The length direction of the output shaft of the first electric push rod 72 is perpendicular to the splicing surface. The first platform body 111 and the second platform body 112 are respectively detachably arranged on the output shaft of the first electric push rod 72.
[0024] When inspecting the lens, the first electric push rod 72 is first used to drive the first platform 111 and the second platform 112 to move away from each other, and then the lens is moved into the placement groove 2, and the corresponding placement groove 2 is selected according to the size of the lens. Then, the first platform 111 and the second platform 112 are separated from the first electric push rod 72, and under the action of the spring 71, the first platform 111 and the second platform 112 are driven to move closer to each other to clamp the lens. The operation is simple and convenient.
[0025] Reference Figure 3 and Figure 4In the embodiment of the present application, in order to facilitate the separation of the first electric push rod 72 from the first platform 111 and the second platform 112, the surfaces of the first platform 111 and the second platform 112 facing the first electric push rod 72 are both provided with connecting holes 73, and the first motor 74 is coaxially arranged on the output shaft of the first electric push rod 72, and a threaded section 75 is arranged on the output shaft of the first motor 74, and a threaded groove threadedly connected to the threaded section 75 is arranged in the connecting hole 73; when the first electric push rod 72 is connected to the first platform 111 and the second platform 112, the first electric push rod 72 drives the first motor 74 to be inserted into the connecting hole 73, and then the first motor 74 is started, and the output shaft of the first motor 74 rotates and is threadedly connected in the threaded groove, so that the first electric push rod 72 is connected to the first platform 111 and the second platform 112; when the first electric push rod 72 is separated from the first platform 111 and the second platform 112, the first motor 74 is started to reverse so that the threaded section 75 and the threaded groove are separated from each other, and the operation is simple and convenient.
[0026] Reference Figure 3 and Figure 4 In order to improve the accuracy of lens eccentricity detection, when the lens is eccentric, due to the small eccentricity of the lens, the first platform 111 and the second platform 112 may abut against each other under the action of the spring 71. Therefore, in the embodiment of the present application, a first suction cup 9 is arranged on the mounting platform 8 and is located in the axial direction of the placement groove 2. The open surface of the first suction cup 9 is away from the mounting platform 8. The first suction cup 9 is used to absorb the lens. A driving motor 10 is arranged on the mounting platform 8. The first suction cup 9 is coaxially arranged on the output shaft of the driving motor 10. After the lens is placed in the placement groove 2, the lens is absorbed on the first suction cup. The first suction cup 9 is placed on the plate 9, and then the driving motor 10 is started. The driving motor 10 drives the first suction cup 9 to rotate. The rotation of the first suction cup 9 drives the lens to rotate. The lens rotates in the placement groove 2. When the lens is eccentric and presents a small ellipse, the lens rotates until the major axis abuts against the inner wall of the placement groove 2. The major axis of the lens pushes the first platform 111 and the second platform 112 to separate, and then approach. During this process, the detection lamp 4 flickers, indicating that the lens is eccentric; when the lens is a standard disc, the rotation of the lens will not push the first platform 111 and the second platform 112 to move, so that the detection lamp 4 is always lit.
[0027] Reference Figure 3 and Figure 4In order to facilitate the first suction cup 9 to be adsorbed on the lens, a mounting plate is provided on the mounting table 8, and the driving motor 10 is fixedly arranged on the mounting plate. A second electric push rod 11 is provided on the mounting table 8, and the length direction of the output shaft of the second electric push rod 11 is perpendicular to the table surface of the mounting table 8. The mounting plate is disc-shaped and coaxially arranged on the output shaft of the second electric push rod 11; after the lens is placed in the placement groove 2, the second electric push rod 11 is started, and the second electric push rod 11 drives the mounting plate to move, and the movement of the mounting plate drives the driving motor 10 to move toward the lens, so as to facilitate the adsorption of lenses of different heights on the first suction cup 9.
[0028] Reference Figure 3 and Figure 4 When the lens is adsorbed on the first suction cup 9, the friction between the lens and the side wall of the placement groove 2 is relatively large during the rotation of the lens, which can easily cause significant wear on the edge of the lens. Therefore, in the embodiment of the present application, the side wall of the placement groove 2 is provided with a lubricating layer for reducing the friction between the side wall of the lens and the side wall of the placement groove 2, and the lubricating layer is a polytetrafluoroethylene layer; under the action of the lubricating layer, the friction between the lens and the side wall of the placement groove 2 is reduced, thereby facilitating the rotation of the lens in the placement groove 2.
[0029] Reference Figure 1 In order to facilitate placing the test lens in the placement groove 2, a vertical rod 12 is arranged on the mounting platform 8, and the length direction of the vertical rod 12 is perpendicular to the mounting platform 8. The cross section of the vertical rod 12 is circular and is a retractable structure. A cross bar 13 is arranged on the vertical rod 12, and the length direction of the cross bar 13 is perpendicular to the length direction of the vertical rod 12. The cross bar 13 is slidably arranged on the telescopic part of the vertical rod 12, and a second suction cup 14 for adsorbing the lens is arranged on the cross bar 13; when the lens is placed, the lens is adsorbed on the second suction cup 14, and then the vertical rod 12 is rotated and the cross bar 13 is slid, and then the vertical rod 12 is retracted, and the vertical rod 12 drives the lens into the placement groove 2. In the above process, the possibility of the inspector contaminating the lens is reduced.
[0030] The implementation principle of a high-stability lens eccentricity detection device in the embodiment of the present application is as follows: When testing the lens, the first electric push rod 72 first drives the first platform 111 and the second platform 112 to move away from each other, and then the lens is moved into the placement slot 2, and the corresponding placement slot 2 is selected according to the size of the lens. Then, the first platform 111 and the second platform 112 are separated from the first electric push rod 72, and under the action of the spring 71, the first platform 111 and the second platform 112 are driven to move closer to each other to clamp the lens; after the lens is placed in the placement slot 2, the lens is adsorbed on the first suction cup 9, and then the drive motor 10 is started, and the drive motor 10 The first suction cup 9 is driven to rotate, and the rotation of the first suction cup 9 drives the lens to rotate. The lens rotates in the placement groove 2. When the lens is eccentric and presents a small ellipse, when the lens rotates until the major axis abuts against the inner wall of the placement groove 2, the major axis of the lens pushes the first platform 111 and the second platform 112 to separate, and then they move closer. During this process, the detection lamp 4 flashes, indicating that the lens is eccentric; when the lens is a standard disc, the rotation of the lens will not push the first platform 111 and the second platform 112 to move, so that the detection lamp 4 is always lit, indicating that the lens is a standard lens.
[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
