Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] like Figures 1-5 As shown, an aspherical optical lens testing platform based on a positioning component includes a protective shell 1, a cover channel 2 on the protective shell 1, a sliding cover 10 slidably connected to the inner wall of the cover channel 2, two fixed guide rails 3 fixed to the top wall of the protective shell 1, a guide rail groove 4 on the fixed guide rail 3, a positioning component slidably connected in one of the guide rail grooves 4, and a limit strip 21 fixed to one of the fixed guide rails 3. A swing-pushing component is connected to the protective shell 1, and a movable pushing component is connected to the sliding cover 10. A movable guide rail 20 is slidably connected inside the sliding cover 10. A guide rail groove 22 is provided on the movable guide rail 20. Another positioning component is slidably connected to the guide rail groove 22. The movable guide rail 20 is connected to the sliding cover 10 through an elastic element 2 19.

[0022] The above structure enables the lens to move and be positioned between guide rail groove 4 and guide rail groove 22, thereby improving the efficiency of lens inspection and replacement.

[0023] Regarding the specific configuration of the swing-pushing component, the swing-pushing component includes a fixed base 6 and a rotating frame 7. The fixed base 6 is fixedly connected to the top wall of the protective shell 1, and the rotating frame 7 is rotatably connected to the fixed base 6. Two permanent magnet blocks 8 and a push plate 9 are fixedly connected to the rotating frame 7.

[0024] By rotating the frame 7 and using the magnetic force between the permanent magnet 8 and the positioning component, the positioning component can be automatically pushed between different guide rails, thereby enabling rapid lens switching.

[0025] Based on the above scheme, the movable push assembly includes an L-shaped strip 12 and a socket 16. The L-shaped strip 12 is slidably connected to the top wall of the sliding cover 10. A movable inclined block 13 and a plug 15 are fixedly connected to the L-shaped strip 12. The L-shaped strip 12 is connected to the sliding cover 10 through an elastic element 14. The socket 16 is fixedly connected to the sliding cover 10. A slot 23 is provided on the socket 16. A press-locking assembly adapted to the plug 15 is provided in the slot 23. The top wall of the protective shell 1 is fixed with a fixed inclined block 5.

[0026] Through the cooperation of the movable inclined block 13 and the fixed inclined block 5, and the locking structure of the plug 15 and the self-locking component, the L-shaped strip 12 can automatically slide to a suitable position and link with the rotating frame 7.

[0027] In some embodiments, the positioning component includes a lens fixing component 17 and a permanent magnet strip 18, which are fixedly connected.

[0028] The lens is stably clamped by the lens fixing component 17, and the clamping structure can refer to the existing technology.

[0029] In a preferred configuration, the rotating frame 7 is rotatably connected to the fixed base 6 via a damping shaft. The damping shaft ensures that the rotating frame 7 maintains its current angle when it rotates to a suitable position.

[0030] To facilitate the movement of the sliding cover 10, a handle 11 is fixedly attached to the sliding cover 10. The handle 11 allows the operator to control the raising and lowering of the sliding cover 10, thereby enabling lens inspection and replacement operations.

[0031] It should be noted that the turntable 7 is in a U shape, and the pushed plate 9 is in a T shape.

[0032] In addition, the socket 16 is fixedly connected to the sliding cover 10 through an extension rod.

[0033] A method for detecting an aspherical optical lens based on a positioning component, which uses the above-mentioned detection platform for aspherical optical lenses based on a positioning component to detect the lens.

[0034] Implementation process: In the initial state, the turntable 7 inclines to the right, the plug 15 is inserted into the slot 23 and locked with the pressing self-locking component. The vertical section of the L-shaped strip 12 is located below the left half of the pushed plate 9. One lens fixing component 17 is located in the left guide groove 4, and the other lens fixing component 17 is located in the guide groove 22.

[0035] Clamp the aspherical lens on the lens fixing component 17 in the guide groove 22. Hold the handle 11 and control the sliding cover 10 to move downwards, so that the sliding cover 10 and the lens enter the detection cavity of the protective shell 1 for detection. The sliding cover 10 can play a role in shading and protection. The fixed inclined block 5 pushes the movable inclined block 13 to move left a small distance, so that the plug 15 is pressed on the pressing self-locking component and remains in the locked state. The detection principle refers to the prior art and will not be limited and described here.

[0036] During the detection process, the operator clamps another lens in the lens fixing component 17 on the left guide groove 4. After one lens is detected, pull the handle 11 upwards to make the sliding cover 10 move upwards. The movable inclined block 13 disengages from the fixed inclined block 5, and the plug 15 is unlocked from the pressing self-locking component. Under the elastic force of the first elastic member 14, the L-shaped strip 12 moves to the right, and its vertical section moves below the right half of the pushed plate 9. When the top wall of the movable guide rail 20 abuts against the bottom wall of the limiting strip 21, the top wall of the movable guide rail 20 is flush with the top walls of the two fixed guide rails 3, so that the guide groove 4 is aligned with the guide groove 22. When the sliding cover 10 continues to move upwards, the movable guide rail 20 remains at the current height, the second elastic member 19 stretches, and the sliding cover 10 continues to move upwards relative to the movable guide rail 20. At the same time, the upper end of the vertical section of the L-shaped strip 12 abuts against the bottom wall of the left half of the pushed plate 9, and the L-shaped strip 12 pushes the pushed plate 9, so that the turntable 7 rotates around the damping rotating shaft and becomes inclined to the left. At this time, the left permanent magnet 8 approaches the permanent magnet strip 18 in the left guide groove 4, and the magnetic repulsive force generated by the permanent magnet 8 pushes the permanent magnet strip 18 to move. The permanent magnet strip 18带动 the lens fixing component 17 to move right along the guide groove 4 into the guide groove 22; at the same time, the permanent magnet strip 18 in the guide groove 22 is pushed by the magnetic repulsive force of the permanent magnet strip 18 in the guide groove 4 and is pushed to带动 the lens fixing component 17 to enter the right guide groove 4 along the guide groove 22, thus completing the rapid replacement of the lens without the need for cumbersome adjustment bolt operations.

[0037] Then, the sliding cover 10 is lowered again into the detection chamber of the protective shell 1 for testing. During this process, when the elastic element 19 returns to a certain length, it drives the movable guide rail 20 to descend together. The movable inclined block 13 moves to the left again under the action of the fixed inclined block 5. The plug 15 is reinserted into the slot 23 and locked with the pressing self-locking component. The L-shaped bar 12 moves to the lower left half of the push plate 9. During testing, the operator removes the lens from the lens fixing component 17 on the right guide rail slot 4 and clamps the new lens onto the lens fixing component 17.

[0038] When the sliding cover 10 moves upward again, the L-shaped bar 12 pushes the push plate 9, causing the rotating frame 7 to tilt to the right again. At this time, the magnetic repulsion force generated by the right permanent magnet block 8 pushes the permanent magnet strip 18 and the lens fixing assembly 17 in the right guide rail groove 1 4 into the guide rail groove 2 22. Meanwhile, the permanent magnet strip 18 and the lens fixing assembly 17 in the guide rail groove 2 22 enter the left guide rail groove 4 under the action of magnetic repulsion, thus completing the rapid lens replacement again. By repeating the above process, continuous and rapid lens replacement and inspection can be achieved, improving inspection efficiency.

[0039] Beneficial effects of this invention: This invention addresses the problem of existing aspherical lens testing devices requiring the individual removal of adjusting bolts, disassembly of lenses, and reinstallation of new lenses after each lens test, resulting in a cumbersome replacement process and low testing efficiency. By installing a fixed guide rail 3, a guide rail groove 4, and a movable guide rail 20 and a guide rail groove 22 within the sliding cover 10 on the protective housing 1, and by installing a lens fixing assembly 17 and a permanent magnet strip 18 within the guide rail groove 4 and guide rail groove 22 respectively, the two lenses can be positioned in the testing and ready positions respectively. After testing, the sliding cover 10 is moved upwards by the control handle 11. The movement guide 20, with the cooperation of the elastic element 29 and the limiting strip 21, aligns the guide groove 4 and the guide groove 22. At the same time, the L-shaped strip 12 moves under the action of the elastic element 14 and pushes the push plate 9, causing the rotating frame 7 to swing. This, in turn, drives the permanent magnet block 8 to approach the permanent magnet strip 18 and generate magnetic repulsion, thereby pushing the lens fixing assembly 17 to move between the guide groove 4 and the guide groove 22. This achieves automatic exchange of the two lens positions, avoiding the need for manual disassembly of the adjusting bolts one by one before the next lens can be inspected. This significantly simplifies the lens replacement process and improves inspection efficiency. Furthermore, the present invention forms an automatic locking and releasing structure through a fixed inclined block 5, a movable inclined block 13, a plug 15, a socket 16, and a slot 23. When the sliding cover 10 descends to enter the detection state, the fixed inclined block 5 pushes the movable inclined block 13 to move, causing the plug 15 to be linked with the self-locking pressing component in the slot 23. This allows the L-shaped bar 12 to move to different positions when the detection is completed and the sliding cover 10 is moved upward. At the same time, the L-shaped bar 12 pushes the push plate 9 to swing the rotating frame 7 to different angles. This, combined with the magnetic repulsion between different permanent magnet blocks 8 and permanent magnet bars 18, enables the rapid exchange of the lens fixing component 17. The lens replacement and detection process can be automatically completed through a single lifting and lowering action of the sliding cover 10. Through this structure, the lens detection and replacement process forms a continuous cyclic operation, eliminating the need to pause for lens replacement. This allows for simultaneous replacement and detection, thereby improving detection efficiency, reducing operational complexity, and facilitating continuous and rapid detection of aspherical lenses.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
