Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
The following detailed description of the embodiments of the utility model, provided in the accompanying drawings, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model discloses an AR (augmented reality) glasses with a hidden two-dimensional code, referring to fig. 1-7, which is used for recording parameter information of the AR glasses and enabling a scanner 40 to easily read the parameter information of the AR glasses, wherein the AR glasses comprise a lens 10, a micro two-dimensional code 20 and an optical amplifying element 30, and the micro two-dimensional code 20 is arranged on the surface of the lens 10 and is used for recording the parameter information of the AR glasses; the optical amplifying element 30 is disposed on the surface of the lens 10 and covers the micro two-dimensional code 20, and is used for amplifying the micro two-dimensional code 20, so that the micro two-dimensional code 20 can be identified by the scanner.
Specifically, the parameter information of the AR glasses is recorded into the micro two-dimensional code 20 with a tiny area and difficult to be perceived, then the micro two-dimensional code 20 is arranged on the surface of the AR glasses lens 10 by means of direct printing, paper pasting/film or laser imprinting, and finally a layer of optical amplifying element 30 is arranged on the surface of the micro two-dimensional code 20, and in the use process, the optical amplifying element 30 focuses the light emitted by the scanner on the micro two-dimensional code 20, so that the scanner can read the information in the micro two-dimensional code 20. The mode can enable the scanner to accurately read the information in the miniature two-dimensional code 20, so that effective tracing of product information is realized, the area of the two-dimensional code is reduced, and good appearance cleanliness and transparency of the AR glasses are ensured.
In the embodiment of the present application, the micro two-dimensional code 20 is provided on the surface of the AR eyeglass lens 10 by the following several methods.
Method one, direct printing: this method typically uses special inks or pigments to print the miniature two-dimensional code 20 directly on the lens 10. Such ink needs to have good adhesion to ensure that the micro two-dimensional code 20 can be firmly adhered to the lens 10. Meanwhile, the ink is also required to have good weatherability and abrasion resistance to ensure that the micro two-dimensional code 20 does not fade or wear during use. An alternative ink is an ultraviolet curable ink that cures rapidly upon exposure to ultraviolet light to form a hard and durable print. Another alternative ink is a laser sensitive ink that can produce a color change upon laser irradiation to form a clear miniature two-dimensional code 20.
Method two, sticker or film: this method typically uses a transparent sticker or film on which the miniature two-dimensional code 20 is printed, and then the sticker or film is attached to the surface of the lens 10. It should be noted that the material of the sticker or film needs to have good transparency and adhesion so that the sticker or film can be firmly adhered to the surface of the lens 10 while ensuring that the micro two-dimensional code 20 is clearly visible. An alternative material is a polyester film which has good transparency and weatherability. It should be noted that when attaching a decal or film to a lens, special glue is required to ensure that the decal or film adheres firmly to the lens, such as a photo-curable glue or pressure sensitive adhesive.
Method three, laser engraving: this method uses a laser to directly imprint the miniature two-dimensional code 20 on the lens 10. This approach may produce very fine and durable miniature two-dimensional codes 20, but may require higher manufacturing costs. Laser scribing typically uses nanosecond or picosecond pulsed lasers that can precisely scribe tiny patterns without burning or damaging the material. For some special materials, such as glass or some plastics, it may also be desirable to use special lasers, such as ultraviolet or femtosecond lasers, to prevent cracking or deformation of the material.
Of these three methods, the laser engraving method of the third method is preferable in the present application to manufacture the micro two-dimensional code 20, because the concealment effect is best and the fineness is high.
In this embodiment, the lens 10 includes an optical path area, a grating area, and other areas except the optical path area and the grating area, wherein the optical path area and the grating area in the lens 10 are important paths for transmitting light rays of the waveguide structure in the AR glasses lens 10, and once the two areas are blocked, the blocking object will greatly affect the developing effect of the AR glasses, so in the embodiment, the micro two-dimensional code 20 is disposed in the other areas to prevent the micro two-dimensional code 20 and the optical amplifying element from affecting the developing effect of the AR glasses. More preferably, in this embodiment, the micro two-dimensional code 20 is disposed in other areas of the lens 10 and near the edge of the lens 10, so that the micro two-dimensional code 20 is less noticeable by a person, and the appearance cleanliness and transparency of the AR glasses are effectively protected.
In this embodiment, the area of the micro two-dimensional code 20 is controlled to be 0.0625-0.25mm 2, so that the information in the micro two-dimensional code 20 can be accurately identified by the scanner while the micro two-dimensional code 20 is not perceived as much as possible.
In this embodiment, the optical magnification element 30 generally includes optional optical elements including microlenses, fresnel lenses, and grating magnification lenses. For micro lenses and fresnel lenses, they can be formed directly on the surface of the two-dimensional code by micro-machining techniques such as micro etching or micro embossing. This method may require the use of special materials such as highly plastic or flexible polymers to ensure that the microlenses are formed accurately.
If the grating magnifying glass is a grating magnifying glass, the grating magnifying glass can be manufactured by directly using a common grating-engraving method, for example, a layer of very thin photoresist is coated on the surface of the two-dimensional code, and then the grating is etched.
Example 1:
In this embodiment, laser scribing is selected as a way of scribing the two-dimensional code. The Laser engraving device Laser precisely stamps a minute micro two-dimensional code 20 on the AR lens 10 using nanosecond or picosecond pulse Laser. The micro two-dimensional code 20 manufactured by the method has extremely high definition and durability, and the optical performance or appearance of the lens 10 is not affected.
In the embodiment, the optical amplifying element 30 selects a micro lens, and the micro lens can be directly formed on the surface of the two-dimensional code by micro processing technology such as micro etching or micro embossing, and the gap between the micro lens and the two-dimensional code is controlled to be within twice focal length, and the gap is preferably between one and twice focal lengths, so that the amplifying effect of the convex lens type amplifying lens is ensured. The micro-lens has good transparency and optical performance, when the scanner emits laser for irradiation, the micro-lens focuses laser on the surface of the two-dimensional code, after the light is reflected by the surface of the two-dimensional code, the light containing information is reflected back to the scanner through the micro-lens, and then the scanning process is completed.
In practical application, when the micro two-dimensional code 20 on the AR spectacle lens 10 is scanned by using the scanner, the micro lens focuses the light of the scanner onto the micro two-dimensional code 20, so that the scanner can read the information of the two-dimensional code conveniently. The method can not only realize effective traceability of product information, but also ensure the appearance neatness and transparency of the product.
Example 2:
In this embodiment, a direct printing method is selected to imprint a two-dimensional code on the lens 10 of the AR glasses. The method uses special ultraviolet curing ink or laser sensitive ink, and uses special printing equipment 50 according to the patterns of the miniature two-dimensional codes 20 to directly print the designed miniature two-dimensional codes 20 on the lenses 10 of the AR glasses. The printing process requires precise control of the distribution and thickness of the ink to ensure the definition and readability of the two-dimensional code. The micro two-dimensional code 20 printed in this way has good definition and durability, is a black-and-white two-dimensional code, has slightly inferior concealment, but is not easily perceived by human eyes due to small volume.
In the embodiment, the optical amplifying element 30 is a fresnel lens, which is directly formed on the surface of the micro two-dimensional code 20 by micro processing technology, such as micro etching or micro embossing. The Fresnel lens has good transparency and optical performance, is thin and light in thickness, and can focus light on the miniature two-dimensional code 20, so that the miniature two-dimensional code 20 is amplified. When the fresnel lens is placed, it is necessary to control the gap between the optical amplifying element 30 and the micro two-dimensional code 20 to be within twice the focal length, and the gap is preferably between one and twice the focal length, so as to ensure the amplifying effect.
Example 3:
In this embodiment, a mode of using a sticker or a film is selected to set the micro two-dimensional code on the AR lens 10 through the glue 60. First, a two-dimensional code is printed on a transparent sticker or film. The material of such a sticker or film needs to have good transparency and adhesion to ensure that the two-dimensional code is clearly visible and can be firmly adhered to the lens 10. Possible material choices include polyester films, which have good transparency and weatherability. A special glue 60, such as a photo-curable glue or pressure sensitive adhesive, is then used to attach the decal or film to the AR lens 10. The method can realize clear printing and firm bonding of the two-dimensional code, and the optical performance or appearance of the lens 10 is not affected.
In the embodiment, a grating magnifying glass is selected as the optical magnifying element 30, and the grating magnifying glass can be directly formed on the surface of the two-dimensional code by micro-processing technology such as micro etching or micro embossing. The grating magnifier has good transparency and optical performance, the volume can be small, and when the laser of the scanner irradiates, light can be dispersed, so that the two-dimensional code can be amplified to facilitate scanning identification.
The advantages are that: the utility model generates the product information into the micro two-dimensional code with the size of millimeter level, attaches the micro two-dimensional code to the AR lens, and then makes a micro optical amplifying structure on the surface of the micro two-dimensional code, wherein the micro optical amplifying structure comprises a micro lens, a Fresnel lens or a grating amplifying structure and the like, and the micro two-dimensional code can be amplified only when the micro two-dimensional code is scanned by a scanner. The mode can enable the scanner to accurately read the information in the miniature two-dimensional code, so that effective tracing of product information is realized, the area of the two-dimensional code is reduced, and good appearance cleanliness and transparency of the AR glasses are ensured.
The above disclosure is only a few specific embodiments of the present utility model, but the present utility model is not limited thereto, and any changes that can be thought by those skilled in the art should fall within the protection scope of the present utility model.
