Description

Technical Field

[0001] This utility model belongs to the field of lens testing technology, and specifically relates to a lens testing device. Background Technology

[0002] Currently, in the lens production process, such as eyeglass lenses or optical lenses, processes such as grinding, chamfering, polishing, and cleaning are required before packaging. However, before being packaged and sold, lenses sometimes need to undergo quality inspections. Lens inspection is a series of important processes to ensure that the quality and performance of lenses meet requirements. Specialized testing equipment is generally used to inspect lenses for diopter, thickness, and appearance. During inspection, the center of the lens needs to be aligned with the inspection head in the inspection assembly. Existing inspection equipment requires range adjustment of the lens position to ensure accurate alignment with the inspection head, which consumes a certain amount of time and causes the lens to rub back and forth with the inspection equipment, increasing lens wear. Furthermore, the process of clamping and limiting the lens with clamping components also causes wear on the lens surface, which is inconvenient and results in poor lens protection and inspection efficiency. Utility Model Content

Detailed Implementation

[0019] Please see Figures 1-4 The present invention provides the following technical solution: a lens testing device, including a testing instrument body 1, a testing platform 11, and a testing component 12. A magnet 2 is provided on the top of the testing platform 11. A magnetic base 21 is detachably connected to the top of the magnet 2. A plurality of connecting screws 3 are provided on the top of the magnetic base 21. A lifting rod 31 is movably connected to the top of the connecting screws 3. A connecting block 33 is fixedly connected to the top of the lifting rod 31. A fixed limiting plate 4 is fixedly connected to the top of the connecting block 33. An adjustable limiting plate 41 is rotatably connected to one side of the connecting block 33. A silicone protrusion 42 is provided on one side of both the fixed limiting plate 4 and the adjustable limiting plate 41.

[0020] In this embodiment: the main structure of the detection equipment is formed by setting up the detector body 1, the detection platform 11, and the detection components 12. The top of the detection platform 11 is provided with a magnetic sheet 2, and the top of the magnetic sheet 2 is detachably connected to a magnetic base 21. After the magnetic sheet 2 and the magnetic base 21 are attracted and connected, they can automatically align. The top of the magnetic base 21 is provided with several connecting screws 3, and the top of the connecting screws 3 is movably connected to a lifting rod 31. The top of the lifting rod 31 is fixedly connected to a connecting block 33. The connecting screws 3, the lifting rod 31, and the adjusting nut 32 form a support frame for lifting and lowering the lens. The top of the connecting block 33 is fixedly connected to a fixing limit plate 4, and the connecting block 33 is fixedly connected to a limiting plate 4. One side of the fixed limiting plate 41 is rotatably connected to an adjustable limiting plate 4. Both the fixed limiting plate 4 and the adjustable limiting plate 41 are provided with silicone protrusions 42 on one side. The fixed limiting plate 4, the adjustable limiting plate 41 and the silicone protrusions 42 form a limiting component for clamping the lens. When the lens is being inspected, the clamping component composed of the four sets of fixed limiting plates 4 and adjustable limiting plates 41 clamps the four edges of the lens. The silicone protrusions 42 provided on one side of the fixed limiting plate 4 and the adjustable limiting plate 41 can increase the friction between the lens and the lens, and can prevent the lens from being worn during the clamping process. After the lens is limited, the magnetic base 21 is attracted to the magnet 2 on the top of the inspection table 11. The magnetic base 21 is connected to the magnetic magnet 21. Under the magnetic attraction, the connecting groove at the bottom allows the magnetic base 21 to automatically align with the magnetic magnet 2. The detection component 12 is positioned at the center of the magnetic magnet 2, ensuring the center of the lens is directly above it. After the magnetic base 21 and the magnetic magnet 2 are attracted, the lens detection point is automatically adjusted and aligned. The adjusting nut 32 is rotated to move up or down on the outside of the connecting screw 3. The adjusting nut 32 is threadedly connected to the connecting screw 3, supporting it. During the up-and-down movement of the adjusting nut 32, the lifting rod 31 slides on the upper end of the connecting screw 3. Adjusting the position of the lifting rod 31 adjusts the distance between the lens and the detection component 12, reducing contact with the lens during detection and friction between the lens and the inspection equipment, thereby reducing lens wear. This allows the new invention to automatically align the detection point with the detection component during lens detection, facilitating lens clamping and limiting. During lens clamping, wear on the lens is avoided, and contact with the lens is reduced during detection, reducing friction between the lens and the inspection equipment, thus protecting the lens, reducing lens contamination, facilitating disassembly and assembly, simplifying operation, and improving efficiency and lens protection during detection.

[0021] The magnet 2 is embedded on the top of the detection stage 11. The magnet 2 is designed as a ring structure, and the detection component 12 is located at the center of the magnet 2. When the detection component 12 is located at the center of the magnet 2, after the magnetic base 21 is attracted to the magnet 2, the lens that is limited between the limiting components at the top of the magnetic base 21 is aligned with the detection component 12, which reduces the adjustment time during detection.

[0022] The magnetic base 21 is designed as a ring structure, and the bottom of the magnetic base 21 is provided with a connecting groove that matches the magnetic sheet 2. The magnetic base 21 and the magnetic sheet 2 are attracted and connected. Under the action of magnetic attraction, the connecting groove at the bottom of the magnetic base 21 enables the magnetic base 21 and the magnetic sheet 2 to automatically align.

[0023] The bottom end of the lifting rod 31 is provided with a threaded connection groove 311 that matches the connecting screw 3. One end of the connecting screw 3 is slidably connected to the inner cavity of the threaded connection groove 311, and an adjusting nut 32 is threadedly connected to the outer side of the connecting screw 3. The connecting screw 3, the lifting rod 31 and the adjusting nut 32 form a support frame for lifting the lens. The position of the lifting rod 31 is adjusted by adjusting the position of the adjusting nut 32, thereby adjusting the distance between the lens and the detection component 12.

[0024] One end of the adjustable limiting plate 41 is provided with a connecting torsion spring 411, and the adjustable limiting plate 41 is rotatably connected to the connecting block 33 through the connecting torsion spring 411; by setting the connecting torsion spring 411, when limiting the lens, it works with the fixed limiting plate 4 to automatically clamp the lens, and can clamp and limit lenses of different degrees, and adjust according to the thickness of the lens.

[0025] Several connecting screws 3 are arranged in a ring array at equal intervals on the top of the magnetic base 21, and the bottom end of the connecting screws 3 is fixedly connected to the top of the magnetic base 21. When several connecting screws 3 are arranged at equal intervals, they clamp and limit the edges of the lens, increasing the stability of the lens.

[0026] The silicone bump 42 is detachably connected to the fixed limiting plate 4 and the adjustable limiting plate 41, and one side of the silicone bump 42 is designed with an arc surface structure. The silicone bump 42 can be replaced, and after disassembly, it can be cleaned to keep it clean and avoid contamination of the lens when limiting the lens.

[0027] The working principle and usage process of this utility model are as follows: When inspecting a lens, a clamping device consisting of four sets of fixed limiting plates 4 and adjustable limiting plates 41 clamps the four edges of the lens. Silicone protrusions 42 on one side of the fixed limiting plates 4 and adjustable limiting plates 41 increase the friction between the lens and the clamping device, preventing wear on the lens during clamping. After the lens is positioned, the magnetic base 21 is attracted to the magnetic sheet 2 on the top of the inspection table 11. The connecting groove at the bottom of the magnetic base 21 automatically aligns the magnetic base 21 with the magnetic sheet 2 under the action of magnetic attraction. The inspection component 12 is positioned at the center of the magnetic sheet 2, ensuring the lens center... The position is directly above the detection component 12, so after the magnetic base 21 and the magnet 2 are attracted, the lens detection point is automatically adjusted and aligned. By rotating the adjusting nut 32, it can be moved up or down outside the connecting screw 3. The adjusting nut 32 is threadedly connected to the connecting screw 3 and supports the connecting screw 3. During the up and down movement of the adjusting nut 32, the lifting rod 31 is driven to slide at the upper end of the connecting screw 3, thereby adjusting the position of the lifting rod 31 and adjusting the distance between the lens and the detection component 12. This reduces contact with the lens during the detection process, reduces friction between the lens and the inspection equipment, and thus reduces wear on the lens.
