Description

[Technical Field]

[0002] This utility model relates to the field of lens processing technology, specifically a lens faceting instrument. [Background Technology]

[0004] With the booming development of industries such as optical instruments and eyeglasses, the scale of the lens processing industry continues to expand, and the market's requirements for lens quality and production efficiency are constantly rising. In the lens processing process, accurately distinguishing the front and back of the lens is a key step, which directly affects the accuracy of subsequent processes such as coating and edge grinding, as well as product quality.

[0005] Traditional lens inspection relies on manual operation, which involves comparing the different R-values ​​(radius of curvature) of the front and back of the lens. However, with the continuous innovation of new lens designs, some high-end lenses use complex curved surface designs during manufacturing to achieve special optical performance, resulting in very similar R-values ​​on the front and back, making them difficult to distinguish with the naked eye and conventional measuring tools. For example, the difference in R-value between the front and back of a certain progressive multifocal lens is only about 0.1mm, which makes it very easy to misjudge during manual inspection. Moreover, manual inspection is not only inefficient, but in large-scale production scenarios, the visual fatigue caused by long hours of work by the inspectors leads to a significant increase in the error rate.

[0006] Therefore, it is necessary to develop a lens facet separation instrument to solve the problems of low efficiency and high error rate in the detection of the front and back of a lens caused by the existing technology of manually detecting the front and back of the lens with the naked eye. [Utility Model Content]

[0032] Please see Figures 1 to 4 The lens faceting instrument shown includes a frame 1, a support plate 2 disposed on the frame 1, and an identification component 3 connected to the support plate 2. The identification component 3 is used to identify the radius of curvature of the lens.

[0033] The identification component 3 includes a carrier housing 31 connected to the carrier plate 2 and a data acquisition component 32. The carrier housing 31 is provided with an illumination element 311 for illuminating the lens and an identification part 312. The carrier housing 31 is located between the data acquisition component 32 and the lens. When the illumination element 311 is activated, the light reflected from the lens can be collected by the data acquisition component 32 through the identification part 312, thereby identifying the radius of curvature of the lens.

[0034] In this invention, the frame serves as the supporting skeleton of the lens faceting instrument, providing a stable mounting base for other components. The support plate, located on the frame, primarily supports the identification component, providing a platform for its installation. Furthermore, the identification component, connected to the support plate, is the core functional component of the instrument, responsible for identifying the radius of curvature of the lens. The identification component further comprises a support housing and a data acquisition component. The support housing contains an illumination element that emits light to provide a light source for the detection process. The support housing also includes an identification section located between the data acquisition component and the lens. When the illumination element is activated, the light reflected from the lens passes through the identification section and is collected by the data acquisition component, thereby identifying the radius of curvature of the lens.

[0035] In summary, by setting up lighting components and recognition components, and by providing a stable light source through the lighting components inside the housing, in conjunction with the recognition unit and data acquisition components, the light emission, reflection and acquisition can be realized, enabling rapid and accurate identification of the curvature radius of the lens. This solves the problems of low detection efficiency and high error rate caused by the existing technology of manually inspecting the front and back of the lens with the naked eye.

[0036] Furthermore, it also includes a base plate 8 connected to the frame 1, the base plate 8 being located below the identification component and used to support the lens.

[0037] Furthermore, the identification unit 312 includes a beam splitter 3121 disposed inside the carrier housing 31. The beam splitter 3121 is inclined and is used to reflect the light emitted by the illumination element 311 to the lens and to allow the light reflected by the lens to pass through.

[0038] In this invention, the identification unit further includes a beam splitter, which is obliquely installed inside the support housing. This beam splitter has special optical characteristics. On the one hand, it can reflect the light emitted by the illumination element, causing the light to illuminate the lens surface at a specific angle and path. On the other hand, after the lens reflects the light, the beam splitter allows these reflected light rays to pass through, enabling them to reach the data acquisition component smoothly. Therefore, the beam splitter greatly improves the efficiency and accuracy of light acquisition. It can precisely control the direction of light, avoid light scattering and interference, and ensure that the illumination light can evenly and effectively illuminate the lens. At the same time, it allows the light reflected by the lens to be completely and accurately received by the data acquisition component. In this way, when detecting the radius of curvature of the lens, more accurate and reliable light data can be obtained, thereby improving the accuracy of identifying the front and back of the lens and providing strong support for improving product quality.

[0039] Furthermore, the carrier housing 31 is also provided with a light-transmitting part 313 and a light-transmitting opening 314 for light to pass through. The light-transmitting part 313 and the light-transmitting opening 314 are respectively located on opposite sides of the carrier housing 31. The light-transmitting part 313 is located between the data acquisition component 32 and the identification part 312. The identification part 312 includes a beam splitter 3122 disposed in the carrier housing 31. The beam splitter 3122 is located between the illumination element 311 and the beam splitter 3121. The beam splitter 3122 is used to split the light emitted by the illumination element 311 into light rays in multiple directions.

[0040] In this invention, the light-transmitting part allows light reflected from the lens to pass through, while the light-transmitting opening allows light emitted from the illumination element to exit the carrier housing and light reflected from the lens to enter the carrier housing. Specifically, light reflected from the lens first enters the carrier housing through the light-transmitting opening, then passes through the beam splitter, and then through the light-transmitting part into the data acquisition component, thus forming a complete optical path. The beam splitter is located inside the carrier housing, spatially positioned between the illumination element and the beam splitter. Light emitted from the illumination element first passes through the beam splitter in its propagation path. The beam splitter, utilizing its unique optical structure and principle, divides incident light rays from a single direction into multiple rays of different directions. The beams of light, after being dispersed, continue to propagate to the beam splitter. After being reflected by the beam splitter, they illuminate the lens surface at multiple angles. The light reflected from the lens then passes through the beam splitter again and is finally collected by the data acquisition component. In summary, the beam splitter divides the light into multiple directions, which can more comprehensively cover the lens surface compared to single-direction illumination. Especially for high-end lenses with complex curved surfaces and small differences in curvature in different areas, multi-angle illumination can capture more subtle curvature changes on the lens surface, avoiding the omission of key features due to a single angle of illumination. This makes the data acquired by the data acquisition component richer and more complete, providing more sufficient basis for accurately identifying the radius of curvature of the lens and effectively improving the comprehensiveness of light acquisition.

[0041] Furthermore, it includes a displacement component 4 that connects the carrier plate 2 and the identification component 3, the displacement component 4 being used to adjust the relative position of the identification component 3 and the lens.

[0042] In this invention, the displacement component connects the support plate and the identification component. The displacement component has a movable and adjustable function, which enables the identification component to change its spatial position, thereby adjusting the relative positional relationship between the identification component and the lens. This adjustment can be a horizontal, vertical, or other directional positional adjustment to adapt to the detection needs of lenses of different sizes, shapes, and thicknesses.

[0043] Therefore, the displacement component significantly enhances the instrument's versatility and flexibility. In actual production, lenses come in a variety of specifications and types. The displacement component allows for easy adjustment of the identification component's position, ensuring that the identification component is in the optimal detection position regardless of the type of lens placed on the carrier plate. This guarantees accurate light acquisition and precise identification of the radius of curvature. This not only improves the instrument's adaptability to different lenses and reduces detection errors caused by differences in lens specifications, but also lowers the company's investment costs in detection equipment. There is no need to configure separate detection instruments for different types of lenses, thus improving production efficiency and economic benefits.

[0044] Furthermore, the displacement component 4 includes a first displacement component 41 and a second displacement component 42, the data acquisition component 32 is connected to the first displacement component 41, the bearing housing 31 is connected to the second displacement component 42, and the first displacement component 41 is located above the second displacement component 42.

[0045] In this invention, the displacement assembly includes a first displacement assembly and a second displacement assembly. The data acquisition assembly is connected to the first displacement assembly, and the support box is connected to the second displacement assembly. The first displacement assembly is located above the second displacement assembly, allowing the data acquisition assembly and the support box to be independently adjusted. The first displacement assembly can precisely adjust the position of the book acquisition assembly to ensure that it can accurately receive the light reflected from the lens. The second displacement assembly can flexibly adjust the position of the support box to ensure that the light emitted by the illumination component can accurately illuminate the lens.

[0046] Therefore, it can be seen that the design of the first and second displacement components greatly improves the precision and accuracy of displacement adjustment. By independently adjusting the data acquisition component and the carrier housing, the emission and acquisition process of light can be controlled more precisely, enabling the instrument to adapt to various complex detection environments and lens types. For example, for lenses with large surface curvature changes and special light reflection angles, the coordinated adjustment of the first and second displacement components can ensure that light can accurately illuminate and reflect, thereby obtaining more accurate detection data. This further improves the accuracy and reliability of lens front and back identification, enhancing the overall performance and detection quality of the instrument. Specifically, the first and second displacement components can move vertically to adjust the distances between the data acquisition component and the lens, the carrier housing and the lens, and the data acquisition component and the carrier housing.

[0047] Furthermore, the displacement assembly 4 also includes a guide rail 43 and a guide rod 44, both connected to the support plate 2. The first displacement assembly 41 is provided with a first limiting part 411 slidably connected to the guide rail 43 and a first adjusting part 412 slidably connected to the guide rod 44. The second displacement assembly 42 is provided with a second limiting part 421 slidably connected to the guide rail 43 and a second adjusting part 422 slidably connected to the guide rod 44. The first adjusting part 412 is used to lock or release the first displacement assembly 41 and the guide rod 44, and the second adjusting part 422 is used to lock or release the second displacement assembly 42 and the guide rod 44.

[0048] In this invention, the guide rail and guide rod provide a stable sliding guide structure for the displacement assembly, ensuring the smoothness and accuracy of the first and second displacement assemblies during movement and reducing displacement deviation. The cooperation between the first and second limiting parts and the guide rail further restricts the movement direction of the displacement assembly, ensuring that it can only slide along the direction of the guide rail. The locking and unlocking functions of the first and second adjusting parts ensure that the displacement assembly can be reliably fixed after being adjusted to a suitable position, avoiding displacement caused by vibration or other factors during the detection process. This ensures the stability and accuracy of light acquisition during the detection process, improves the accuracy and reliability of lens curvature radius recognition, and ensures the consistency and repeatability of the instrument's detection results.

[0049] Furthermore, the identification component 3 also includes a display screen 7 connected to the rack 1. The display screen 7 is electrically connected to the data acquisition component 32 and is used to display the identification result of the data acquisition component 32.

[0050] This invention features a display screen electrically connected to a data acquisition component. After acquiring data on the reflected light from the lens, the data acquisition component processes and analyzes the data internally, transmitting the final identification structure to the display screen in an intuitive image or digital format. As a crucial human-computer interaction interface, the display screen allows operators to directly obtain information on the lens's radius of curvature and the determination of the lens's front and back sides. This effectively improves the visualization of the detection results and the ease of operation. Operators can obtain detection results from the display screen without needing complex data processing equipment or additional analysis methods, significantly shortening the feedback time of detection information and improving work efficiency. Specifically, the data acquisition component can be a camera.

[0051] Furthermore, it also includes a sealing plate 9 connected to the frame, the sealing plate 9 being located on the upper side, around the perimeter, or at the bottom of the identification component 3.

[0052] This invention provides a sealing plate 9 connected to the frame on the upper side, around the perimeter, or at the bottom of the identification component 3. This effectively prevents dust, water, and external physical damage, protects internal precision components from environmental influences, and prevents external light from entering the instrument and interfering with the lens detection results. This effectively improves the reliability and accuracy of lens curvature detection.

[0053] Furthermore, it also includes a data processing unit electrically connected to the display screen and the data acquisition component, the data processing unit being used to analyze image data and identify the curvature characteristics of the lens surface.

[0054] Furthermore, the illumination element 311 illuminates the beam splitter 3121 in a horizontal direction, and the angle α formed by the beam splitter 3121 and the horizontal plane is in the range of 30-60°.

[0055] In this invention, the light emitted by the illumination element illuminates the beam splitter horizontally. The angle α formed between the beam splitter and the horizontal plane ranges from 30° to 60°. This specific angle setting and light illumination direction ensure that the illumination light, after being reflected by the beam splitter, can be successfully collected by the data acquisition component. The light perpendicularly illuminating the lens can more evenly cover the lens surface, reducing blind spots and allowing the curvature characteristics of the lens surface to be more clearly reflected by the reflected light. At the same time, the appropriate angle of reflected light ensures that the light can accurately pass through the beam splitter and be received by the data acquisition component, avoiding light loss and interference. This design plays an important role in improving the accuracy and stability of lens curvature radius detection, especially for lenses that are sensitive to light angle and illumination method, effectively improving the accuracy and reliability of the detection results.

[0056] Furthermore, the displacement component 4 also includes a limiting block 45, which is located at both ends of the guide rod 44.

[0057] In this invention, the limiting blocks are installed at both ends of the guide rod. Their main function is to limit the movement range of the first and second displacement components on the guide rod. When either the first or second displacement component moves along the guide rod to a position close to the limiting block, the limiting block prevents it from moving further, thus preventing the displacement component from exceeding its reasonable movement range. This effectively prevents damage to the internal structure of the instrument or impact on detection accuracy due to excessive movement of the displacement component, ensuring that the instrument operates within its normal working range. Simultaneously, the limiting blocks also provide a clear definition of the initial position and movement range of the displacement component, facilitating reference for operators when adjusting the displacement component. This improves the accuracy and efficiency of displacement adjustment, reduces detection errors caused by improper displacement, ensures the stability and reliability of the instrument, and extends its service life.

[0058] Furthermore, there are two guide rails 43, and the two guide rails 43 and the guide rod 44 are parallel to each other and extend in a vertical direction.

[0059] This invention enhances the stability and accuracy of the vertical movement of the displacement component by setting the number of guide rails to two and extending them vertically. Compared with a single guide rail, two guide rails can provide more uniform support force, reducing the possibility of tilting or swaying of the displacement component during movement. This ensures that the first and second displacement components can move along a precise path. This stable movement structure is crucial for improving the accuracy of the relative position adjustment between the recognition component and the lens, ensuring the stability and consistency of the light acquisition process, thereby improving the accuracy and reliability of lens curvature radius detection and providing a solid structural guarantee for high-quality lens inspection.

[0060] Working principle: When using a lens facet measuring instrument to inspect a lens, the following steps are included:

[0061] During the preparation phase, the lens to be tested is placed on the base, and the relative position of the recognition component and the lens is adjusted using the displacement components. Specifically, the positions of the data acquisition component and the carrier box are adjusted by the first displacement component and the second displacement component, respectively. The first limiting part and the first adjusting part on the first displacement component work in conjunction with the guide rail and the guide rod, and the corresponding parts on the second displacement component are treated similarly to ensure that the data acquisition component can be in the optimal shooting position, and that the lighting component and the recognition component in the carrier box can also maintain a suitable positional relationship with the lens, thus preparing for subsequent testing.

[0062] During the light emission and propagation phase, the illumination device is turned on, which emits light. The light first passes through a beam splitter and is divided into multiple beams in multiple directions. Then, the light propagates to a beam splitter, which reflects the light and shoots it out of the carrier housing through the light-transmitting port, so that the light shines on the surface of the lens at a specific angle.

[0063] In the light reflection and acquisition stage, after light shines on the lens surface, it is reflected due to the curvature of the lens surface. The reflected light returns along the original path and re-enters the carrier box through the light-transmitting port. When it passes through the beam splitter again, it passes through the beam splitter and the light-transmitting part, and is emitted from the carrier box. Then it is captured by the data acquisition component. The data acquisition component receives the light signal, converts it into an electrical signal, and then forms image data.

[0064] During the data processing and output stage, the data acquisition component transmits the acquired data to the instrument's built-in data processing unit. The data processing unit uses specific algorithms to analyze the image data, identify the curvature characteristics of the lens surface, calculate the radius of curvature of the lens, and finally transmits the processing results to the display screen for display. Operators can intuitively obtain the judgment results of the front and back of the lens.
