Description

Technical Field

[0001] This invention belongs to the field of biomimetic mechanical technology, and in particular relates to a fiber optic biomimetic eyeball device and its manufacturing method. Background Technology

[0002] In the current era of rapid development in bionic robot technology, the bionic eyeball, as a core component for enhancing the anthropomorphism and objectification of devices, directly determines the overall performance and user experience of bionic devices through its display effect and structural rationality. It is a crucial guarantee for bionic robots to achieve a lifelike effect. Currently, existing bionic eyeball technologies generally employ complex mechanical transmission devices to simulate eyeball movements such as rotation and gaze. Specifically, through the coordinated operation of multiple mechanical components such as motors, gears, and linkages, the eyeball structure is driven to adjust its posture, thereby achieving a basic bionic effect.

[0003] However, the aforementioned existing technologies have obvious defects and shortcomings, making it difficult to meet the diversified and large-scale application needs of bionic devices: the core problem lies in the over-reliance on complex mechanical devices, which greatly increases the difficulty of structural design, makes the assembly and debugging process cumbersome and time-consuming, and makes the motion control logic complex and prone to failure; at the same time, the use of a large number of mechanical parts not only increases the cost of raw materials, but also increases the difficulty of manufacturing process and subsequent maintenance costs, making the overall cost high, which seriously restricts the large-scale production and widespread promotion of the technology, and cannot be adapted to the diverse application scenarios of various humanoid robots and mechanical animals.

[0004] To address the core pain points of existing technologies, such as complex structure, difficult assembly and debugging, cumbersome motion control, and high cost, there is an urgent need for a new type of bionic eye display device and its manufacturing method. This would simplify structural design, reduce production costs, improve bionic effects, enrich bionic functions, meet the practical application needs of various bionic devices, and promote the further development of bionic robot technology. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing bionic eyeball technologies, which rely on complex mechanical transmission devices, resulting in difficulties in structural design, assembly and debugging, motion control, and high production costs. This invention provides a fiber optic bionic eyeball and its manufacturing method. Through innovative structural design, this invention eliminates complex mechanical transmission components and utilizes a combination of curved fiber optic elements and a display to achieve a realistic display of the bionic eyeball. It also adds bionic functions for different colored pupils and pupil contraction and dilation, reducing design, manufacturing, and control costs, improving the applicability and bionic realism of the device, and addressing many deficiencies of existing technologies.

[0006] To achieve the above objectives, the present invention provides a fiber optic bionic eyeball device.

[0007] The device has a simple structure, mainly consisting of a display, two fiber optic components, and a fixing fixture. The structure, materials, and connections of each component are scientifically and rationally designed to ensure that the structure is simplified while meeting the requirements of biomimetic display, as detailed below:

[0008] Fiber optic components: Two components are used, each corresponding to one of the bionic eyes. The input end is a flat planar structure, while the output end consists of a spherical structure adapted to the bionic eyeball and a bionic curved cornea structure. See below:

[0009] The optical fiber element can be either a glass optical fiber element or a polymer optical fiber element. Both materials can meet the image transmission requirements. Glass optical fiber elements have better light transmittance and stability, while polymer optical fiber elements have the advantages of being lightweight, tough, and lower in cost. The choice can be made flexibly according to the actual application scenario. The optical fiber element realizes image transmission based on the total internal reflection characteristic of light. It can accurately convert the planar image received at the input end into a curved image output that matches the curvature of the eyeball. Its size is adapted to the actual size of the bionic eyeball, ensuring the realism of the display. At the same time, by preset different colored pupil patterns and dynamic images of pupil contraction and dilation on the display, different colored pupil bionic and pupil contraction and dilation bionic functions can be realized, further enhancing the anthropomorphic effect of the bionic eyeball and conforming to the natural state of the biological eyeball.

[0010] Display: A flat panel display device is used, and its configuration can be flexibly selected according to actual application needs: The first option is to configure a square or circular display for each fiber optic element, with the two displays corresponding to the planar input ends of the two fiber optic elements respectively; the second option is to configure a rectangular display for both fiber optic elements, with the display area size of the rectangular display matching the overall size of the planar input ends of the two fiber optic elements. The core function of the display is to play planar dynamic images corresponding to eye movements, including images corresponding to eye rotation, fixation, pupil color switching, pupil contraction and dilation, etc. The planar dynamic images can be preset or intelligently adjusted according to actual needs, providing clear and synchronized image input to the fiber optic elements and ensuring the smoothness of the biomimetic effect.

[0011] The fixture's core function is to precisely position and securely fix the two fiber optic components. Specifically, the two fiber optic components need to be arranged according to the normal eye spacing of the bionic device, ensuring that their relative positions match the natural eye layout of the bionic device. Simultaneously, the fixture must ensure a tight fit between the flat ends of the fiber optic components and the display surface, guaranteeing a seamless contact surface and preventing light leakage or misalignment during image transmission. This ensures the stability and clarity of image conversion, providing a foundation for the realization of bionic pupil color and pupil dilation / contraction functions. The fixture is made of wear-resistant and corrosion-resistant hard materials to prevent deformation during long-term use and ensure the long-term stability of the device.

[0012] The working principle and process of this device are simple and easy to understand, requiring no complex control logic: Technicians pre-design planar dynamic images corresponding to biomimetic movements such as eye movement, fixation, pupil color switching, and pupil contraction and dilation, and play these planar dynamic images at the corresponding positions on the display; the planar dynamic images output by the display are transmitted to the planar input ends of two fiber optic elements, and through the total internal reflection transmission effect of the optical fibers of the fiber optic elements, the planar images are accurately converted into curved images that match the curved surfaces of the output ends of the fiber optic elements and then output; since the two fiber optic elements are arranged according to the normal eye spacing of the biomimetic body, the curved images they output can perfectly simulate the visual effects of the biomimetic body's eyes, thereby achieving all-round biomimetic display of the eyeballs, which can complete the simulation of various eyeball movements without any mechanical transmission parts, and the movements are smooth and natural.

[0013] Manufacturing method of fiber optic bionic eyeball display device: This manufacturing method has a simple process and clear steps, which is conducive to large-scale production and can effectively reduce manufacturing costs. Specifically, it includes the following steps:

[0014] 1. Fiber Optic Component Fabrication: Based on actual application requirements, single or composite fiber filaments are selected as raw materials. The fiber filaments are tightly packed and heated to form fiber optic component blanks. The two ends of the blanks are processed through grinding and polishing to form a flat plane (i.e., the input end) at one end and a spherical or corneal biomimetic curved surface (i.e., the output end) at the other end. The fabricated fiber optic components are cleaned to remove surface impurities, ensuring the clarity of image transmission and ensuring that the details of the pupil and the dynamics of pupil contraction and dilation can be accurately presented.

[0015] 2. Fixture Preparation: Based on the normal eye distance parameters of the bionic body and the display setting method of the fiber optic element (single fiber optic element corresponding to a single display or dual fiber optic elements corresponding to a single display), a fixture is designed and manufactured. The fixture needs to reserve a precise positioning structure to ensure that the two fiber optic elements can be accurately fixed according to the eye distance, and at the same time, a display mounting position is reserved to facilitate the tight fit between the flat end of the fiber optic element and the display surface. The fixture material is selected from wear-resistant and corrosion-resistant hard materials, which are processed and polished before use to ensure the stability and service life of the fixture.

[0016] 3. Assembly and Combination: Assemble the components according to the preset display settings: If each fiber optic element is paired with a square or round display, align the two displays with the planar input ends of the two fiber optic elements respectively, and then use clamps to position and fix the fiber optic elements and displays together, ensuring that the fiber optic elements and displays are tightly fitted without gaps; if two fiber optic elements are paired with a rectangular display, arrange the two fiber optic elements in the clamp according to eye spacing, adjust the posture so that the planar input ends of the two fiber optic elements are on the same plane, then press the display surface of the rectangular display tightly against the planar input ends of the two fiber optic elements, and fix it firmly with clamps. Adhesive or compression methods can be used to assist in fixing, further ensuring the stability of image transmission.

[0017] 4. Debugging and Testing: Connect the assembled device to the power supply and play preset planar dynamic images such as eye movements, pupil color switching, and pupil contraction and dilation. Check whether the curved surface image output by the fiber optic element is clear and complete, whether the output images of the two fiber optic elements are synchronized, whether the fixture is firmly fixed, and whether the dynamic bionic effect of the pupil color and pupil meets the standards. If there are problems such as blurry images, offset, loose fixation, or poor bionic effect, make targeted adjustments and calibrations until the bionic display requirements are met and the manufacturing is completed.

[0018] The technical effects of this invention are as follows:

[0019] Simplified structure: It abandons the complex mechanical transmission components in the existing technology and consists only of a display, fiber optic components and fixtures. The simple structural design greatly reduces the difficulty of structural design and assembly debugging, which is conducive to mass production and fundamentally solves the core pain point of complex structure in the existing technology.

[0020] Cost reduction: The use of mechanical parts is reduced, resulting in a significant decrease in raw material costs, manufacturing process costs, and subsequent maintenance costs. At the same time, the shape of the optical fiber components can be customized, and either glass or polymer materials can be selected, allowing for flexible choices based on cost requirements. This further enhances the product's market competitiveness and solves the problem of high costs associated with existing technologies.

[0021] Simple control: No complex motion control algorithm is required. Only the corresponding planar dynamic image needs to be designed and played. The biomimetic eye movements, pupil color switching, and pupil contraction and dilation can be realized through fiber optic components. This reduces the difficulty of control, avoids the malfunctions such as jamming and deviation caused by mechanical transmission, and improves the stability of the device.

[0022] More realistic bionic effect: The output end of the fiber optic element adopts a spherical or corneal bionic curved surface design, combined with a dual fiber optic element structure arranged according to eye distance, perfectly simulating the visual effect of the bionic eyes; at the same time, it adds bionic functions of different colored pupils and pupil contraction and dilation, which can simulate different colored pupils and dynamic adjustment of pupils under changes in light, further improving the anthropomorphism and objectification of the bionic robot, breaking through the limitation of the single function of existing bionic technology, and conforming to the natural state of biological eyeballs.

[0023] Wide applicability: The display can be set up flexibly (single fiber element corresponds to a single display, dual fiber element corresponds to a single display), and the material and shape of the fiber element can be flexibly selected. It can be adapted to humanoid robots and mechanical animals of different sizes and types. There is no need to redesign complex mechanical structures for different devices. It has a wide range of applications and can meet the application needs of diversified bionic devices. Attached Figure Description

[0043] Example 1

[0044] like Figures 1-2 As shown, this embodiment provides a fiber optic bionic eyeball display device and its manufacturing method, suitable for adult humanoid robots. It employs a configuration of two fiber optic cones (hereinafter referred to as fiber optic cones), each paired with a circular display, as detailed below:

[0045] Fiber Optic Tap: Two glass fiber optic taps are used, and the whole is shaped like an inverted cone. The diameter of the input end of each fiber optic tap is 15mm and the height of the tap is 30mm. The output end is a spherical structure with the radius of curvature of the sphere being consistent with the radius of curvature of an adult eyeball, ensuring that the display effect fits the bionic eyeball. The glass fiber optic tap has good light transmittance and can accurately present the details of the pupil and the dynamics of pupil contraction and dilation.

[0046] Display: It adopts two small LCD flat panel displays, which are circular in shape and have a display area size of φ15mm. The size of the display area matches the overall size of the plane input end of the fiber optic cone (the distance between the two plane input ends of the fiber optic cone is 60mm, and the overall width is adapted to the length of the display). It can play preset planar dynamic images such as eye movement, gaze, color pupil switching (such as black, brown, blue), pupil contraction and dilation, etc., with a frame rate of 30fps to ensure smooth dynamic display and natural color pupil and pupil dynamic switching.

[0047] The clamp is made of aluminum alloy and features a positioning groove designed according to the normal interpupillary distance of an adult (approximately 60mm). Two fiber optic taps are fixed in the positioning groove to ensure a 60mm spacing. The clamp is equipped with an adjustable clamping structure to press the flat end of the fiber optic tap against the display surface of the LCD monitor, preventing gaps and ensuring stable image transmission. This ensures clear color pupil and pupil bionic effects. The aluminum alloy material is wear-resistant and corrosion-resistant, ensuring long-term stable use of the device.

[0048] Working process: The preset planar dynamic images of eyeballs moving left and right, looking up and down, changing pupil color, and pupil contraction and dilation are imported into a circular LCD display; the images enter through the planar input ends of two fiber optic cones, are transmitted to the spherical output end through total internal reflection of the glass fiber bundle, and are converted into curved images for output; the curved images output by the two fiber optic cones simulate the movements of the bionic eyes, while clearly presenting different pupil colors and pupil contraction and dilation effects, achieving a highly realistic display of the bionic eyeball, without any mechanical rotating parts, and the movements are smooth and natural.

[0049] Manufacturing method:

[0050] 1. Fiber taper fabrication: Composite fiber filaments are stacked in an orderly and compact manner and then hot-pressed and drawn into a tapered blank; the small end of the taper is ground and polished using a grinding machine to form a flat plane (input end); the large end of the taper is spherically ground, controlling the radius of curvature of the sphere to 30mm to form a spherical output end; after grinding, the surface of the fiber taper is cleaned with anhydrous ethanol to remove impurities and burrs, and then dried for later use to ensure clear image transmission and meet the detailed requirements of color pupil and pupil biomimicry.

[0051] 2. Fixture preparation: Based on the adult eye distance of 60mm, the structure of the aluminum alloy fixture is designed, and positioning grooves matching the fiber optic tap are opened with a spacing of 60mm. Adjustable clamping bolts are set on the top of the fixture to secure the fiber optic tap to the display. The aluminum alloy raw material is CNC machined into the fixture, and after grinding and rust prevention treatment, it is ready for use to ensure the stability and service life of the fixture.

[0052] 3. Assembly: Place the two prepared glass fiber taps into the positioning slots of the fixture, adjust their posture so that the planar input ends of the two fiber taps are on the same plane; place the circular LCD display on one side of the planar input end of the fiber tap, adjust its position so that the display surface is completely in contact with the planar input ends of the two fiber taps, tighten the clamping bolts to fix it, ensure no gaps, and guarantee the stable transmission of color pupil and pupil dynamic images.

[0053] Debugging and testing: Turn on the monitor power and play the preset eye dynamic image, pupil switching image, and pupil contraction and dilation image. Observe whether the curved image output by the fiber optic cone is clear and complete, whether the two images are synchronized, whether the pupil details and pupil dynamic effects meet the standards, and whether the fixture is firmly fixed. If the image is blurry, adjust the fit between the fiber optic cone and the monitor. If the image is offset or the bionic effect is poor, adjust the positioning of the fiber optic cone in the fixture. After the debugging is qualified, the manufacturing is completed.

[0054] Example 2

[0055] like Figures 3-4As shown, this embodiment provides a fiber optic bionic eyeball display device and its manufacturing method, suitable for adult humanoid robots. It adopts a configuration of two fiber optic panels and a rectangular display, as detailed below:

[0056] Fiber Optic Panel: Two glass fiber optic panels are used, each cylindrical in shape. The input end of each fiber optic panel has a diameter of 30mm and a cylinder height of 20mm. The output end has a spherical structure with a radius of curvature consistent with that of an adult cornea, ensuring that the display effect closely matches the bionic eye. The glass fiber optic panel has good light transmittance, enabling it to accurately present the details of the pupil and the dynamics of pupil contraction and dilation.

[0057] Display: A small LCD flat panel display is used, which is rectangular in shape and has a display area size of 95mm×35mm. The display area is matched with the overall size of the flat input end of the two fiber optic panels (the distance between the flat input ends of the two fiber optic panels is 60mm, and the overall width is adapted to the length of the display). It can play preset flat dynamic images such as eye movement, gaze, color pupil switching (such as black, brown, blue), pupil contraction and dilation, etc., with a frame rate of 30fps to ensure smooth dynamic display and natural color pupil and pupil dynamic switching.

[0058] The clamp is made of aluminum alloy and features a positioning groove designed according to the normal eye distance of an adult (approximately 60mm). Two cylindrical fiber optic panels are fixed in the positioning groove to ensure a 60mm spacing. The clamp is equipped with an adjustable clamping structure to press the flat end of the fiber optic panel tightly against the display surface of the LCD monitor, preventing gaps and ensuring stable image transmission and clear color pupil and pupil bionic effects. The aluminum alloy material is wear-resistant and corrosion-resistant, ensuring long-term stable use of the device.

[0059] Working process: The preset planar dynamic images of eyeballs moving left and right, looking up and down, changing color pupils, and pupil contraction and dilation are imported into a rectangular LCD display, and the display plays the images in the corresponding positions. The images enter through the planar input ends of two fiber optic panels, are transmitted to the spherical output end through total internal reflection of the glass fiber bundle, and are converted into curved images for output. The curved images output by the two fiber optic panels simulate the movements of the bionic eyes, while clearly presenting different color pupils and pupil contraction and dilation effects, achieving a highly realistic display of the bionic eyeballs. There are no mechanical rotating parts, and the movements are smooth and natural.

[0060] Fiber optic panel fabrication: Composite fiber filaments are stacked in an orderly and compact manner and hot-pressed into shape; the blank is cut and milled into a cylindrical structure with a diameter of 30mm and a height of 20mm; one end of the cylinder is ground and polished using a grinding machine to form a flat plane (input end); the other end is spherically ground, controlling the radius of curvature of the sphere to be 30mm, forming a spherical output end; after grinding, the surface of the fiber optic panel is cleaned with anhydrous ethanol to remove impurities and burrs, and then dried for later use to ensure clear image transmission and meet the detailed requirements of color pupil and pupil biomimicry.

[0061] Fixture fabrication: Based on an adult eye distance of 60mm, the structure of the aluminum alloy fixture is designed, with two positioning slots matching the cylindrical fiber optic panel. The positioning slots are spaced 60mm apart. An adjustable clamping bolt is installed on the top of the fixture to secure the fiber optic panel to the display. The aluminum alloy raw material is CNC machined into the fixture, which is then polished and rust-proofed before use to ensure the stability and service life of the fixture.

[0062] Assembly: Place the two prepared glass fiber panels into the positioning slots of the fixture, adjust their posture so that the planar input ends of the two fiber panels are on the same plane; place the rectangular LCD display on one side of the planar input end of the fiber panel, adjust its position so that the display surface of the display is completely in contact with the planar input ends of the two fiber panels, tighten the clamping bolts to fix it, ensure no gaps, and guarantee the stable transmission of color pupil and pupil dynamic images.

[0063] Debugging and testing: Turn on the monitor power and play the preset eye dynamic image, pupil switching image, and pupil contraction and dilation image. Observe whether the curved image output by the fiber optic panel is clear and complete, whether the two images are synchronized, whether the pupil details and pupil dynamic effects meet the standards, and whether the fixture is firmly fixed. If the image is blurry, adjust the fit between the fiber optic panel and the monitor. If the image is offset or the bionic effect is poor, adjust the positioning of the fiber optic panel in the fixture. After the debugging is qualified, the manufacturing is completed.

[0064] Example 3

[0065] like Figures 5-6 As shown, this embodiment provides a fiber optic bionic eye display device and its manufacturing method. The difference between this embodiment and Embodiment 2 is that: it is adapted to small mechanical animals (such as bionic pet dogs), and adopts a configuration where each fiber optic panel is equipped with a circular display. The fiber optic panels are polymer fiber optic panels, as detailed below:

[0066] Device Structure: Two polymer fiber optic panels are used, each cylindrical in shape. The input end of each panel is circular with a diameter of 20mm, and the cylinder height is 10mm. The output end is a biomimetic corneal surface, with its radius of curvature designed based on the parameters of a small robotic animal's eye. The polymer fiber optic panels are lightweight and flexible, suitable for small biomimetic devices, and can clearly display the details of the robotic animal's pupil color and the dynamics of pupil contraction and dilation. Two small OLED circular displays are used, each with a display area diameter of 20mm, corresponding to the flat input ends of the two fiber optic panels. Common pupil colors of robotic animals (such as black and brown) and corresponding dynamic images of pupil contraction and dilation can be preset at a frame rate of 25fps to ensure smooth dynamic display. The fixture is made of engineering plastic, making it even lighter. Positioning slots are designed according to the interpupillary distance of small robotic animals (approximately 50mm) to position and fix the two fiber optic panels and two circular displays, ensuring a tight, seamless fit between the flat ends of the fiber optic panels and the display surfaces, guaranteeing stable image transmission.

[0067] Manufacturing method: Basically the same as in Example 2, with adjustments only made in the following steps: When preparing the fiber optic panel, polymer fiber bundles are selected to form a cylindrical structure blank with a diameter of 20mm and a height of 20mm. The output end is ground into a corneal bionic curved surface adapted to the eyeball of a small mechanical animal. When preparing the fixture, a positioning groove is designed according to a 50mm interpupillary distance, and mounting positions for two circular displays are reserved. The fixture is made of engineering plastic. During assembly, the two circular displays are aligned with the planar input ends of the two polymer fiber optic panels respectively, and then fixed together by the fixture. During debugging and testing, the focus is on testing whether the color pupil and pupil dynamic bionic effect match the eyeball characteristics of a small mechanical animal. After successful debugging, manufacturing is completed.

[0068] Figure 9 The diagram illustrates the fiber optic assembly structure in Example 2 or Example 3. The fiber optic element can be either a glass fiber optic element or a polymer fiber optic element; both materials meet the image transmission requirements. Glass fiber optic elements offer better light transmittance and stability, while polymer fiber optic elements are lightweight, durable, and cost-effective, allowing for flexible selection based on the specific application scenario. The fiber optic element achieves image transmission based on the total internal reflection characteristic of light, accurately converting the planar image received at the input end into a curved image output that matches the curvature of the eyeball. Its size is adapted to the actual size of the bionic eyeball, ensuring the realism of the display. Simultaneously, by pre-setting different colored pupil patterns and dynamic pupil contraction and dilation images on the display, different colored pupil bionic and pupil contraction and dilation bionic functions can be achieved, further enhancing the anthropomorphic effect of the bionic eyeball and conforming to the natural state of a biological eyeball.

[0069] Example 4

[0070] like Figures 7-8As shown, this embodiment provides a fiber optic bionic eyeball display device and its manufacturing method.

[0071] The difference between this embodiment and embodiments 1, 2, and 3 is that the fiber optic panel used is a specially customized shape, and each fiber optic panel is equipped with a circular display. This method utilizes the customizable shape of the fiber optic panel to further enhance the advantages of this embodiment in terms of structural flexibility and wide applicability. Details are as follows:

[0072] Device Structure: Two fiber optic panels are used, their shape customized to meet specific needs (an example uses a near-elliptical shape). The output end is a biomimetic curved surface inspired by the eyeball, with its radius of curvature designed based on eyeball parameters. Two small circular OLED displays are used, each with a display area diameter of 30mm, corresponding to the planar input ends of the two fiber optic panels. Common pupil colors (such as black and brown) and corresponding dynamic images of pupil contraction and dilation can be preset at a frame rate of 25fps to ensure smooth dynamic display. The clamps are made of engineering plastic, making them lighter. Positioning slots are designed according to the normal eye distance of an adult (approximately 60mm) to position and fix the two fiber optic panels and two circular displays, ensuring a tight, seamless fit between the planar ends of the fiber optic panels and the display surfaces, guaranteeing stable image transmission.
