Technical Field
[0002] The present invention relates to the technical field of smart glasses, and in particular to a lens processing technology, a lens and smart glasses. Background Art
[0003] With the development of smart wearable devices, various new electronic products are constantly being developed, and smart glasses are one of them. Smart glasses need to realize data transmission function and are generally equipped with antennas to receive and send signals.
[0004] However, antennas of existing display devices are usually installed by providing a special mounting base or mounting bracket on the frame. Such antenna fixing structure is relatively complicated, increases the difficulty of installation, and leads to high cost. Summary of the Invention
[0005] The main purpose of the present invention is to provide a lens processing technology, aiming to reduce the complexity of antenna assembly.
[0006] To achieve the above-mentioned object, the present invention proposes a lens processing process, wherein the lens comprises at least a first main layer, a patch antenna, and a second main layer stacked together, wherein one of the first main layer and the second main layer is a waveguide plate, and the other is a protective plate. The lens processing process comprises the following steps:
[0007] Laminating the first side of the patch antenna to the first main layer;
[0008] Lay the second main layer on the second side of the patch antenna.
[0009] Optionally, the step of laminating the first side of the patch antenna to the first main layer includes:
[0010] tearing off a portion of the release paper on the first side of the patch antenna;
[0011] Lay the portion of the release paper on the first side of the patch antenna onto the first main sheet;
[0012] Tear off the remaining release paper on the first side of the patch antenna, and stick the first side of the patch antenna as a whole on the first main layer.
[0013] Optionally, when a portion of the release paper on the patch antenna is torn off, the proportion of the torn release paper to the entire release paper ranges from 1 / 2 to 2 / 3.
[0014] Optionally, before tearing off the remaining release paper, air bubbles between the patch antenna attached to the first main layer and the first main layer are first removed.
[0015] Optionally, after the patch antenna is entirely attached to the first main sheet layer, all bubbles between the patch antenna and the first main sheet layer are discharged.
[0016] Optionally, after all bubbles between the patch antenna and the first main layer are exhausted, the patch antenna is pressed to maintain pressure between the patch antenna and the first main layer.
[0017] Optionally, when the patch antenna includes an antenna body and a PET film for attaching the antenna body, and the antenna body is provided inside the PET film, before attaching the second main sheet layer to the second side of the patch antenna, a double-sided tape is first attached to the second side of the patch antenna, and the second main sheet layer is attached to the second side of the patch antenna by the double-sided tape; or
[0018] When the patch antenna includes an antenna body, and the antenna body is attached to the release paper; the patch antenna is entirely attached to the first main sheet layer, and before the second main sheet layer is attached to the second side of the patch antenna, double-sided tape is first attached to the first main sheet layer, and the second main sheet layer is attached to the first main sheet layer through the double-sided tape to form an antenna gap between the double-sided tape, the first main sheet layer and the second main sheet layer, and the antenna body is located in the antenna gap.
[0019] Optionally, before tearing off part of the release paper on the patch antenna, the first main layer is positioned on a positioning fixture.
[0020] The present invention also provides a lens, which is manufactured using the above-mentioned lens processing technology.
[0021] The present invention also provides a pair of smart glasses comprising the above-mentioned lenses.
[0022] The above lens processing technology has at least the following beneficial effects:
[0023] The technical solution of the present invention utilizes a patch antenna with its first side bonded to a first main sheet and a second main sheet bonded to its second side. Specifically, in the prior art, the antenna is typically located outside the lens, on the housing of the smart glasses. The patch antenna of this solution is transparent and sheet-like, positioned between the first and second main sheets. This allows the first and second main sheets to protect the patch antenna from both sides, effectively protecting it from damage. Furthermore, positioning the patch antenna between the first and second main sheets prevents the antenna from occupying space within the housing, thereby conserving space and making the smart glasses more compact. By bonding the first side of the patch antenna to the first main sheet and then bonding the second main sheet to its second side, this layered assembly method simplifies assembly, reduces patch antenna assembly complexity, improves the yield rate of the lenses produced, and ultimately reduces the production cost of the lenses, ultimately reducing the production cost of the smart glasses.

[0042] The present invention provides a lens processing technology.
[0043] 4 and 5 , in one embodiment of the present invention, the lens 100 of the lens processing process includes at least a first main layer 110, a patch antenna 120, and a second main layer 130 stacked on each other, one of the first main layer 110 and the second main layer 130 being a waveguide plate, and the other being a protective plate. The lens processing process includes the following steps: laminating the first side of the patch antenna 120 on the first main layer 110; and laminating the second main layer 130 on the second side of the patch antenna 120.
[0044] Specifically, in the prior art, the antenna is generally located outside the lens 100, on the housing of the smart glasses. The patch antenna 120 of this solution is in the form of a transparent sheet and is located between the first main sheet 110 and the second main sheet 130. This allows the first and second main sheets 110, 130 to protect the patch antenna 120 from both sides, effectively protecting the patch antenna 120 from damage. Furthermore, locating the patch antenna 120 between the first and second main sheets 110, 130 prevents the antenna from occupying space within the housing, thereby saving space and making the smart glasses more compact.
[0045] This solution laminates the first side of the patch antenna 120 onto the first main layer 110, and then laminates the second main layer 130 onto the second side of the patch antenna 120. This layer-by-layer lamination method simplifies assembly operations, helps reduce the complexity of assembling the patch antenna 120, improves the lamination yield of the lens 100, improves the yield rate of the produced lens 100, and thus reduces the production cost of the lens 100, ultimately achieving the effect of reducing the production cost of the smart glasses.
[0046] It should be noted that this solution takes the first main layer 110 as a protective sheet and the second main layer 130 as a waveguide sheet as an example. Of course, in some other embodiments, the first main layer 110 can also be a waveguide sheet and the second main layer 130 can also be a protective sheet.
[0047] 6 to 8 , further, a release paper 122 is provided on the first side of the patch antenna 120. It can be understood that the release paper 122 is a protective paper for the patch antenna 120. This can prevent dust from adhering to the surface of the patch antenna 120 and affecting the bonding effect between the first side of the patch antenna 120 and the first main layer 110. The release paper 122 can also protect the unbonded patch antenna 120.
[0048] The step of laminating the first side of the patch antenna 120 to the first main sheet 110 includes: tearing off a portion of the release paper 122 on the first side of the patch antenna 120; laminating the portion of the first side of the patch antenna 120 where the release paper 122 was torn off to the first main sheet 110 (denoted as S2); and tearing off the remaining release paper 122 on the first side of the patch antenna 120 and laminating the entire first side of the patch antenna 120 to the first main sheet 110 (denoted as 4). This allows the patch antenna 120, after the release paper 122 is torn off, to be promptly laminating to the first main sheet 110, thereby reducing the chance of dust in the air adhering to the first side of the patch antenna 120.
[0049] Optionally, when part of the release paper 122 on the patch antenna 120 is torn off, the proportion of the torn release paper 122 to the whole is in the range of 1 / 2 to 2 / 3. It can be understood that the smaller the length of the release paper 122 peeled off, the closer it is to the patch antenna 120. The first time the release paper 122 is torn off, the proportion of the whole is in the range of 1 / 2 to 2 / 3. In this way, the release paper 122 can be relatively far away from the patch antenna 120, reducing the interference of the peeled release paper 122 with the patch antenna 120 and the first main layer 110, thereby improving the bonding efficiency.
[0050] Furthermore, before tearing off the remaining release paper 122, the bubbles between the patch antenna 120 that has been attached to the first main layer 110 and the first main layer 110 are first discharged, which is recorded as S3. It can be understood that the bubbles between the patch antenna 120 that has been attached to the first main layer 110 and the first main layer 110 are first discharged because the bonding area is smaller. The bubble removal distance at this time is shorter than the bubble removal distance after the patch antenna 120 is entirely attached to the first main layer 110. It can be seen that before tearing off the remaining release paper 122, the bubbles between the patch antenna 120 that has been attached to the first main layer 110 and the first main layer 110 are first discharged, which is more convenient for discharging bubbles.
[0051] It should be noted that the bubble removal distance is the distance between the bubble and the edge of the bonding surface between the patch antenna 120 and the first main sheet layer 110 .
[0052] Furthermore, after the patch antenna 120 is integrally attached to the first main layer 110, all bubbles between the patch antenna 120 and the first main layer 110 are discharged, which is recorded as S5. Similarly, this makes it easier to discharge the bubbles between the patch antenna 120 and the first main layer 110.
[0053] The purpose of removing all bubbles between the patch antenna 120 and the first main layer 110 is to prevent the bubbles from affecting the clarity of the lens 100 .
[0054] Optionally, after all bubbles between the patch antenna 120 and the first main layer 110 are expelled, the patch antenna 120 is pressed, recorded as S6, so that the patch antenna 120 and the first main layer 110 are kept under pressure, so as to ensure the clarity between the patch antenna 120 and the first main layer 110.
[0055] 8 and 9 , optionally, in one embodiment, when the patch antenna 120 includes an antenna body 121 and a PET film to which the antenna body 121 is attached, and the antenna body 121 is disposed inside the PET film, the shape of the PET film is the same as that of the first main layer 110 , and release paper 122 is provided on both sides of the PET film.
[0056] At this time, before attaching the second main layer 130 to the second side of the patch antenna 120, first attach the double-sided tape 140 to the second side of the patch antenna 120. The second main layer 130 is attached to the second side of the patch antenna 120 through the double-sided tape 140, which is recorded as S8. This makes it easier to stack the layers and improves the stacking yield.
[0057] It should be noted that the PET film is transparent and colorless, and does not affect the optical properties of the lens 100. PET film also has high heat resistance, allowing for advantages such as low-temperature reflow soldering. The antenna body 121 being disposed within the PET film means that the surface of the antenna body 121 does not protrude from the surface of the PET film. It can be embedded within the PET film or entirely buried within the PET film.
[0058] Optionally, in the second embodiment, when the patch antenna 120 includes an antenna body 121, and the antenna body 121 is attached to the release paper 122; the patch antenna 120 is entirely attached to the first main layer 110, and before the second main layer 130 is attached to the second side of the patch antenna 120, the double-sided tape 140 is first attached to the first main layer 110, and the second main layer 130 is attached to the first main layer 110 through the double-sided tape 140 to form an antenna gap between the double-sided tape 140, the first main layer 110 and the second main layer 130, and the patch antenna 120 is located in the antenna gap, which is recorded as S7. This can facilitate layer-by-layer stacking and improve the stacking yield.
[0059] Among them, this solution uses double-sided tape 140 for bonding. This is because double-sided tape 140 is convenient and easy to use. Double-sided tape 140 is a very convenient and easy-to-use glue that can be used without additional tools and equipment. It only needs to tear off the protective paper on the back and stick the glue on the first main layer 110 and the second main layer 130 that need to be bonded, or the second main layer 130 and the patch antenna 120. Compared with traditional glue and tape, double-sided tape 140 is simpler and faster to use, eliminating many useless steps and making bonding more convenient. Secondly, the double-sided tape 140 has good viscosity and can work at any temperature and humidity. Therefore, no matter what environment it is used in, it can maintain stable adhesion. Therefore, using double-sided tape 140 can improve the bonding stability of the first main layer 110 and the second main layer 130, and the second main layer 130 and the patch antenna 120. Furthermore, using the double-sided tape 140 can greatly save time, because it is very convenient to use, there is no need to wait for the glue to dry, and there is no need to wait for multiple parts to be attached, so a lot of time can be saved.
[0060] 6 , optionally, before tearing off part of the release paper 122 on the patch antenna 120, the first main layer 110 is first positioned on the positioning fixture 700, which is denoted as S1. It can be understood that this solution increases the stability of the position of the first main layer 110 by positioning the first main layer 110 on the positioning fixture 700, thereby avoiding displacement of the first main layer 110 during the stacking process, thereby reducing the fit between the patch antenna 120 and the first main layer 110, improving the yield rate of the lens 100, and thus reducing the production cost of the smart glasses.
[0061] 10 and 11 , the lens 100 further includes a third main layer 150 . After the second main layer 130 is adhered to the second side of the patch antenna 120 , the third main layer 150 is adhered to the side of the second main layer 130 facing away from the patch antenna 120 .
[0062] Among them, before the third main layer 150 is adhered to the side of the second main layer 130 facing away from the patch antenna 120, the double-sided tape 140 is first adhered to the side of the second main layer 130 facing away from the patch antenna 120, which is recorded as S9, and the third main layer 150 is adhered to the second main layer 130 through the double-sided tape 140, which is recorded as S10.
[0063] It can be understood that the provision of the third main layer 150 can better protect the waveguide plate and the patch antenna 120 , thereby being beneficial to increasing the service life of the lens 100 .
[0064] Furthermore, the third main patch is attached to the side of the second main layer 130 facing away from the patch antenna 120 using double-sided tape 140. This is because double-sided tape 140 is convenient and easy to use, requiring no additional tools or equipment. Simply remove the protective paper on the back and apply the adhesive to the third main layer 150 and the second main layer 130 to be bonded. Compared to traditional glue and tape, double-sided tape 140 is much simpler and faster to use, eliminating many unnecessary steps and making bonding much more convenient. Furthermore, double-sided tape 140 has excellent adhesion and operates in all temperature and humidity conditions, maintaining stable adhesion regardless of the environment. Therefore, using double-sided tape 140 improves the bonding stability between the third main layer 150 and the second main layer 130. Furthermore, using double-sided tape 140 significantly saves time. Because it is extremely convenient, there's no need to wait for the glue to dry or for multiple components to be attached, saving significant time.
[0065] Specifically, the first main layer 110 and the third main layer 150 are both configured as protective sheets, and the second main layer 130 is a waveguide sheet. The first main layer 110 can be an inner protective sheet close to the human eye or an outer protective sheet away from the human eye. In this embodiment, the first main layer 110 is the inner protective sheet close to the human eye.
[0066] The present invention further provides a lens manufactured using the above-described lens processing technology. The specific structure of this lens is similar to the above-described embodiments. Since this lens utilizes all the technical solutions of all of the above-described embodiments, it possesses at least all the beneficial effects of the technical solutions of the above-described embodiments, and therefore will not be further elaborated here.
[0067] The present invention also proposes a pair of smart glasses, which include lenses. The specific structure of the smart glasses refers to the above embodiment. Since the lenses adopt all the technical solutions of all the above embodiments, they at least have all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
[0068] 1 to 3 , the smart glasses include a support 200, a lens 100 and an optical engine 300, wherein the lens 100 and the optical engine 300 are mounted on the support 200; the patch antenna 120 of the lens 100 includes an antenna body 121 and a coaxial line 400 electrically connected to the antenna body 121, and the coaxial line 400 has a shielding layer; the support 200 is conductive, the coaxial line 400 is fixed to the support 200, and the shielding layer is electrically connected to the support 200 to achieve grounding of the patch antenna 120.
[0069] Smart glasses such as AR glasses require built-in patch antennas 120 for receiving signals such as Wifi and Bluetooth. Coaxial cable 400 feeding is a common feeding method for patch antenna 120. However, the electrical length of the longer coaxial cable 400 is comparable to the operating wavelength of the patch antenna 120, and the shielding layer of the coaxial cable 400 has a strong surface current distribution, which affects the impedance matching and consistency of the patch antenna 120. This solution electrically connects the shielding layer of the coaxial cable 400 to the conductive support 200, so that the support 200 not only has its own supporting effect, but also can improve the surface current distribution of the shielding layer of the coaxial cable 400, improve the effect of the surface current on the impedance matching and consistency of the patch antenna 120, and improve the performance of the patch antenna 120. Therefore, this solution can save the additional grounding structure, thereby reducing the space occupied by the grounding structure, improving the space utilization of the smart glasses, and further improving the compactness of the smart glasses.
[0070] Furthermore, the coaxial line 400 also has an outer insulating layer covering the shielding layer, and when the coaxial line 400 is peeled, multiple grounding positions are spaced apart along its length, exposing the shielding layer at the grounding positions for electrical connection with the support member 200. It is understood that collisions are inevitable during use or transportation, and collisions can easily cause the grounding positions to become electrically disconnected from the support member 200, that is, the shielding layer and the support member 200 to become electrically disconnected. In this solution, multiple grounding positions are provided on the coaxial line 400. Even if the electrical connection between a particular grounding position and the support member 200 is disconnected, the remaining grounding positions remain electrically connected to the support member 200. This ensures the stability of the electrical connection between the shielding layer and the support member 200, thereby improving the performance of the patch antenna 120.
[0071] Optionally, a protective layer is provided on the outer surface of the support member 200, and the support member 200 is provided with an electrical connection position corresponding to each grounding position. The protective layer is removed at the electrical connection position to electrically connect it with the shielding layer of the corresponding grounding position. It can be understood that by first removing the protective layer on the outer surface of the support member 200 and then electrically connecting the electrical connection position with the shielding layer of the corresponding grounding position, the influence of the protective layer on the electrical connection can be avoided, thereby increasing the stability of the grounding of the patch antenna 120.
[0072] The electrical connection points are configured as laser engraved points. Specifically, these points are where the protective layer on the outer surface of the support member 200 is removed through a laser engraving process. Laser engraving offers high precision, accurately removing the protective layer at fixed locations, thereby reducing machining errors and improving the fit between the electrical connection points and the grounding points. Furthermore, the laser engraving process is low-cost: it is fast, the process is completed in one go, and energy consumption is low. Furthermore, the laser engraving process offers high processing efficiency, which can improve the production efficiency of smart glasses.
[0073] The electrical connection position is configured as a grinding position. Specifically, the grinding position refers to a position where a protective layer on the outer surface of the support member 200 is removed by a grinding process.
[0074] The protective layer may be a coating layer. When the support member 200 is a metal support member 200 , the protective layer may also be an oxide layer.
[0075] Optionally, the electrical connection position and the grounding position are electrically connected through a conductive adhesive 500. This is because, firstly, the conductive adhesive 500 has good conductivity and can effectively conduct current, which can improve the conductivity between the shielding layer and the support member 200. Secondly, the conductive adhesive 500 is easy to process and can be easily processed into various forms. When the conductive adhesive 500 is used to conduct the shielding layer and the support member 200, the conductive adhesive 500 can adapt to the gap between the shielding layer and the support member 200 and form a specific form, thereby reducing the operational difficulty of conduction between the shielding layer and the support member 200. Thirdly, the conductive adhesive 500 has a long service life and will not reduce its conductivity and adhesion over time. Therefore, using the conductive adhesive 500 to conduct the support member 200 and the shielding layer can not only ensure the stability of the grounding of the shielding layer, but also increase the stability of the connection between the support member 200 and the shielding layer. Fourthly, the conductive adhesive 500 also has excellent plasticity and scalability, and can be coated, printed, sprayed, and other processing methods on substrates of different shapes and sizes formed between the shielding layer and the support member 200, reducing the difficulty of operation. Fifthly, the conductive adhesive 500 has excellent adhesion properties, so the conductive adhesive 500 can also increase the connection strength between the coaxial line 400 and the support member 200. Sixthly, the conductive adhesive 500 has high stability. During the preparation process, the conductive adhesive 500 can control its conductive performance and stability by adjusting parameters such as the composition of the colloidal matrix and the concentration of the conductive particles. In this way, it can be formulated according to the current intensity of the shielding layer of the coaxial line 400 of the smart glasses, which can better improve the surface current's impact on the impedance matching and consistency of the patch antenna 120. Seventhly, the conductive adhesive 500 has a low cost, which can reduce the grounding cost of the smart glasses.
[0076] Among them, the conductive glue 500 can be silver powder conductive glue 500, carbon conductive glue 500, copper silver conductive glue 500, carbon nanotube conductive glue 500 water, silver paste conductive glue 500 water, conductive epoxy resin glue, nickel coated conductive glue 500 water or high viscosity conductive glue 500 water and other conductive glue 500, and no specific restrictions are made on the conductive glue 500 here.
[0077] In other embodiments, copper oxide paste may also be used to achieve grounding of the support member 200 and the shielding layer.
[0078] Optionally, the outer insulating layer of the coaxial line 400 is bonded and fixed to the support member 200 . This is because the bonding connection method is simple and can improve the connection efficiency between the coaxial line 400 and the insulating layer.
[0079] Furthermore, the outer insulating layer of the coaxial line 400 is bonded to the support member 200 by means of the structural adhesive 600. This is because the structural adhesive 600 has high strength, which can improve the connection strength between the outer insulating layer of the coaxial line 400 and the support member 200, and reduce the probability of unstable connection between the outer insulating layer of the coaxial line 400 and the support member 200, thereby affecting the grounding effect between the support member 200 and the shielding layer. Secondly, the structural adhesive 600 has a short curing time, which can greatly improve the connection efficiency between the outer insulating layer of the coaxial line 400 and the support member 200, thereby improving the production efficiency of the smart glasses. Furthermore, the structural adhesive 600 is waterproof and shockproof, making the smart glasses more durable. Of course, the present invention is not limited to this. In other embodiments, the outer insulating layer of the coaxial line 400 can also be directly bonded to the support member 200 by means of the conductive adhesive 500.
[0080] This solution connects the coaxial line 400 and the outer insulating layer and the support member 200 through structural adhesive 600, and electrically connects the shielding layer and the support member 200 through conductive adhesive 500, so as to achieve stable fixation and excellent grounding effect of the coaxial line 400.
[0081] Furthermore, the structural adhesive 600 is configured as UV adhesive (shadowless adhesive, photosensitive adhesive or ultraviolet light curing adhesive). This is because the UV adhesive can cure quickly, which can greatly improve the connection efficiency between the outer insulating layer of the coaxial cable 400 and the support 200, thereby improving the production efficiency of the smart glasses. Secondly, the UV adhesive has strong adhesion, which can improve the connection strength between the outer insulating layer of the coaxial cable 400 and the support 200, and reduce the probability of unstable connection between the outer insulating layer of the coaxial cable 400 and the support 200, which affects the grounding effect between the support 200 and the shielding layer. Moreover, the odor is small, which can reduce the odor of the smart glasses and improve the comfort of the user. Furthermore, the reliability of the UV adhesive is high, which can improve the connection stability between the outer insulating layer of the coaxial cable 400 and the support 200. Of course, the present invention is not limited to this. In other embodiments, the structural adhesive 600 can also be configured as a polyurethane structural adhesive 600 (PUR) or a polycarbonate structural adhesive 600 (PC).
[0082] Optionally, the coaxial line 400 is provided with a plurality of bonding positions spaced apart along its length direction, and the plurality of bonding positions and the plurality of connection positions are alternately arranged in sequence, which can increase the stability of the electrical connection between the connection positions and the electrical connection positions.
[0083] Optionally, the support member 200 is the frame of the smart glasses or an independent component located in the frame. Specifically, the present solution achieves grounding through the frame of the smart glasses or an independent component located in the frame. This can save an additional grounding structure, thereby reducing the space occupied by the grounding structure, improving the space utilization of the frame, and further improving the compactness of the frame.
[0084] Furthermore, in this embodiment, the support member 200 is made of a conductive metal. This is because conductive metal not only has excellent electrical conductivity but also possesses high strength and rigidity. This metal can improve current distribution on the surface of the shielding layer of the coaxial cable 400 while providing more stable support for the imaging device. Of course, the present invention is not limited to this. In other embodiments, the support member 200 can also be made of a conductive non-metal, as long as it can achieve both electrical conductivity and support.
