Description

Technical Field

[0001] This disclosure relates to the field of waveguide lens technology, and in particular to a rapid detection device and method for waveguide lenses, which is especially suitable for the rapid detection of nose bridge fractures in one-to-two optical-mechanical waveguide lenses in AR glasses. Background Technology

[0002] Waveguide lenses are the core optical components in AR glasses that enable the transmission and display of optical signals, such as... Figure 1 The schematic diagram of the waveguide lens in the related technology shown illustrates that the waveguide lens utilizes total internal reflection to couple the image light emitted from the optical engine through the coupling grating 1. The light is then deflected and guided through the left and right deflecting gratings 11 and 13 in the bridge area, respectively, to the left and right output gratings 12 and 14, and then output outwards. In this dual-mode optical engine waveguide solution for AR glasses, the bridge area of ​​the waveguide lens must withstand mechanical loads such as assembly stress and drop impacts, making it highly susceptible to micro-cracks invisible to the naked eye or even complete breakage. Once the bridge breaks, the optical path is interrupted, resulting in severe optical defects such as an image displayed on one side and no display on the other. Furthermore, in actual production, the waveguide lens is prone to breakage at multiple stages, including frame pressure holding, glue removal, temple pressure holding, and tension testing. Because the mid-frame and cover plate completely obscure the breakage point on the bridge, and the crack is extremely small (micrometer-level), it cannot be directly identified by visual inspection.

[0003] In existing technologies, waveguide lens breakage detection typically employs two methods: 1. Visual inspection with the entire device illuminated: After the AR glasses are fully assembled, the left and right sides are observed for normal display by illuminating an optical engine. However, this method only detects problems after the entire assembly process is complete, and once waveguide breakage is detected, rework costs are extremely high. 2. Visual microscopic inspection: After disassembling the glasses frame, a high-powered microscope is used to directly observe the surface of the waveguide lens in the bridge area for cracks. This method is destructive testing (requiring disassembly), has extremely low detection efficiency, significant cost losses, and a high rate of missed detections. It is only suitable for sampling inspection or failure analysis and cannot be used for batch full inspection on production lines. Summary of the Invention

[0004] This disclosure provides a rapid detection device and method for waveguide lenses, in order to solve the problems of delayed detection after assembly (detection can only be carried out after assembly is completed), low detection efficiency, and high detection cost in the related art for waveguide lens breakage detection.

[0005] The waveguide lens rapid testing device provided in this embodiment includes a mounting fixture, a laser module, and a receiver. The mounting fixture has a mounting part for fixing the waveguide lens under test, and the mounting part is further provided with a first position corresponding to the first coupling grating in the waveguide lens under test, and a second position corresponding to the second coupling grating. The laser module is positioned toward the first location and is used to inject test laser into the first coupling grating in the first location. The receiver is at least partially oriented toward the second location for receiving light emitted from the second coupling grating in the second location.

[0006] In one embodiment, the waveguide lens rapid detection device further includes a fixed base; The top of the fixed base is provided with a clearance opening for avoiding the first area and the second area; The laser module is positioned above the clearance opening, and the laser in the laser module can be moved and adjusted toward or away from the clearance opening.

[0007] In one embodiment, the laser can also reciprocate along the length and width of the clearance opening to adjust the relative position of the laser and the first coupling grating in the waveguide lens under test.

[0008] In one possible implementation, the laser module further includes a light shield; The light shield is correspondingly installed on the top and periphery of the laser module, allowing only the bottom of the laser module to communicate with the clearance opening.

[0009] In one embodiment, the side of the fixed base is also provided with a plug-in port; The mounting fixture can be at least partially inserted into and fixed to the fixed base through the plug-in port, or removed from the fixed base through the plug-in port.

[0010] In one embodiment, the mounting fixture is further provided with a clamping part for manual or robotic gripping; When the mounting fixture is inserted and fixed to the fixed base, the clamping part is located outside the insertion port.

[0011] In one possible embodiment, the receiving element is fixedly connected to the top of the fixed base and located above the clearance opening; Along the light emission direction of the second coupling grating in the second location, the receiver is inclined at an acute angle to the light emission direction.

[0012] In one possible implementation, the receiving device is one or more of a reflector, a silicon photovoltaic cell, or a photodiode; Furthermore, when the receiver includes a silicon photovoltaic cell or a photodiode, the receiver is also electrically connected to a digital display for recording light intensity information.

[0013] In addition, this disclosure also provides a rapid detection method for waveguide lenses, applicable to the aforementioned rapid detection device for waveguide lenses, which includes the following steps: The waveguide lens to be tested is fixedly mounted on the mounting fixture; Align the laser module with the output grating on one side of the waveguide lens under test, and align the receiver with the output grating on the other side of the waveguide lens under test. The test laser is emitted from the laser module toward the coupling grating on one side of the waveguide lens under test. Observe and determine the light spot condition in the receiver; If the receiver has no light spot or the light spot intensity is lower than a preset threshold, the waveguide lens under test is determined to be a defective lens. If the receiver has a light spot and the intensity of the light spot is higher than a preset threshold, then the waveguide lens under test is determined to be a good lens.

[0014] In one possible implementation, the step of emitting a test laser through the laser module toward the coupling grating on one side of the waveguide lens under test includes: The light source output port of the laser module is placed close to the coupling grating on one side of the waveguide lens under test, and the external ambient light of the laser module is shielded by a light shield. Then, a test laser with a wavelength range of 430nm~680nm is emitted into the coupling grating, and the wavelength of the laser module is matched with the main wavelength of the optomechanical system in the waveguide lens under test.

[0015] The technical solution provided in this disclosure has the following advantages compared with related technologies: The waveguide lens rapid inspection device provided in this disclosure eliminates the need to power on the optical engine in AR glasses. It independently inspects the integrity of the waveguide lens using only the laser source of a laser module. This can be completed before or during the assembly of the AR glasses' optical engine, effectively preventing subsequent invalid assembly due to micro-fractures in the waveguide lens and significantly reducing rework costs. Furthermore, when using this rapid inspection device, inspectors can visually observe whether there is a light spot output in the receiver, or collect and display information about the light spot intensity in the receiver through a light intensity receiving module. Inspectors can complete the judgment within a very short time (seconds), making it suitable for 100% full inspection of production line products.

[0016] Furthermore, the rapid waveguide lens testing method provided in this embodiment can be applied to the aforementioned rapid waveguide lens testing device. It only requires performing the above four steps to quickly determine the good condition of the waveguide lens under test, and has the beneficial effects of simple operation steps, rapid testing process, and accurate testing results.

[0017] Unlike existing technologies that align the light source with a coupling grating for image transmission performance testing, this disclosure innovatively directs the test laser into an output grating on one side of a waveguide lens. Utilizing the total internal reflection channel of the waveguide lens, the output light is received from the output grating on the other side. By determining the presence or intensity of the output light, the presence or absence of a break at the nose of the waveguide lens can be quickly identified. This disclosure eliminates the need for complex optical lens assemblies and optical path deflection elements, resulting in an extremely simple structure, low cost, and fast testing speed.

[0022] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0024] Combination Figure 2 and Figure 3 As shown, this embodiment of the present disclosure provides a rapid testing device for waveguide lenses, which includes a mounting fixture 2, a laser module 3, and a receiver 4. The mounting fixture 2 has a mounting portion for fixing the waveguide lens under test, and the mounting portion is further provided with a first position 21 corresponding to the first coupling grating in the waveguide lens under test, and a second position 22 corresponding to the second coupling grating (wherein, the first coupling grating and the second coupling grating can be either the left coupling grating in the waveguide lens or the right coupling grating in the waveguide lens). The laser module 3 is disposed towards the first position 21 for injecting test laser into the first coupling grating in the first position 21. The receiver 4 is disposed towards the second position 22 for receiving the light emitted from the second coupling grating in the second position 22.

[0025] In practical use, the waveguide lens rapid testing device provided in this embodiment can first fix a bare waveguide lens, a semi-finished waveguide lens (before or during optomechanical assembly), or a finished waveguide lens (after optomechanical assembly) in the mounting part of the mounting fixture 2. Specifically, the first coupling grating 12 in the waveguide lens under test can be correspondingly set with the first position 21 in the mounting part, and the second coupling grating 14 in the waveguide lens under test can be correspondingly set with the second position 22 in the mounting part. Then, the test laser can be shone into the first coupling grating 12 in the first position 21 through the laser module 3 (the coupling grating is usually considered as the output end, but in this application it is used as the input end in reverse, and no turning element is needed). Finally, it is observed whether the receiver 4 receives the light emitted from the second coupling grating 14 in the second position 22. In this way, it can be determined whether there are microcracks or fractures in the nose area of ​​the waveguide lens.

[0026] The waveguide lens rapid detection device provided in this embodiment can, based on the principle of total internal reflection light transmission of waveguide lenses, detect if the nose bridge area of ​​the waveguide lens under test (corresponding to...) Figure 1If the first output grating 1 is intact and unbroken, the light coupled into the waveguide lens can satisfy the total internal reflection condition inside the waveguide lens, thus allowing it to travel along the complete optical path to the second output grating 14 and be emitted outwards. The receiver 4 can then receive the light and display the light spot, allowing the inspector to determine if the waveguide lens under test is a good lens. If the bridge area of ​​the waveguide lens under test (corresponding to...) is intact and unbroken, the light entering the waveguide lens can satisfy the total internal reflection condition inside the waveguide lens, allowing it to travel along the complete optical path to the second output grating 14 and be emitted outwards. The receiver 4 can then receive the light and display the light spot, allowing the inspector to determine if the waveguide lens under test is a good lens. Figure 1 If there is a microcrack or breakage at the coupling grating 1 in the waveguide lens, the light coupled into the first coupling grating 12 will not be able to meet the total internal reflection condition inside the waveguide lens. The coupled light will have difficulty transmitting along the complete optical path to the second coupling grating 14 and being emitted outward. As a result, the receiver 4 will not receive any light or will only receive a small amount of light. The receiver 4 will not be able to display a light spot or will only display a weak light spot. In this way, the tester can determine that the waveguide lens under test is a defective lens.

[0027] Compared to existing technologies that use full-machine visual inspection or external microscope examination for waveguide lens breakage detection, the rapid waveguide lens inspection device provided in this disclosure eliminates the need to illuminate the optical engine in the AR glasses. It independently inspects the integrity of the waveguide lens using only the laser source of the laser module 3. This can be completed before or during the assembly of the AR glasses' optical engine, effectively avoiding subsequent invalid assembly due to micro-fractures in the waveguide lens and significantly reducing rework costs. Furthermore, when using this rapid waveguide lens inspection device, inspectors only need to visually observe whether there is a light spot output in the receiver 4, or collect and display the light spot intensity information in the receiver 4 through the light intensity receiving module. Inspectors can complete the judgment within a very short time (seconds), making it suitable for 100% full inspection of production line products.

[0028] It is also worth noting that the waveguide lens rapid testing device provided in this embodiment has a simple structure and low cost. It only requires a low-power laser module 3, a simple mounting fixture 2, and a receiver 4 (which can be configured as a light receiving plate, light intensity sensor, etc.). It does not require a complex electronic system, and the cost of a single set can be less than 200 yuan, which is significantly lower than the cost of existing optical performance testing equipment. Moreover, the laser module 3 can replace laser light sources of different wavelengths (such as green light for single green optical engine waveguides and red light for full-color waveguides), and can be flexibly adapted to various optomechanical schemes according to the effective wavelength of the waveguide lens.

[0029] In one embodiment, the waveguide lens rapid detection device further includes a fixed base 5; the top of the fixed base 5 is provided with a clearance opening 51 for avoiding the first location 21 and the second location 22; the laser module 3 is disposed above the clearance opening 51, and the laser 31 in the laser module 3 can be moved toward or away from the clearance opening 51 for adjustment.

[0030] Specifically, in combination Figure 2 and3 To elaborate further, the fixed base 5 may be, but is not limited to, a plate-shaped base, and the clearance opening 51 at the top of the fixed base 5 may be, but is not limited to, a rectangular opening. Moreover, the clearance opening 51 can be directly above the first position 21 and the second position 22 along the vertical direction of the fixed base 5. In this way, the laser module 3, which is set above the clearance opening 51, can adjust the distance between the laser 31 and the waveguide lens under test in the first position 21 by moving downward toward the clearance opening 51 or moving upward away from the clearance opening 51, so as to ensure that the laser 31 can be aligned with the waveguide lens under test in the first position 21, so that the laser 31 can accurately emit detection laser toward the first coupling grating 12 in the waveguide lens under test.

[0031] It is also worth noting that the lifting and adjusting method of the laser 31 mentioned above can be achieved, but is not limited to, through a "motor + gear and rack transmission mechanism".

[0032] In one embodiment, the laser 31 can also reciprocate along the length and width of the clearance opening 51 to adjust the relative position of the laser 31 and the first coupling grating in the waveguide lens under test.

[0033] Specifically, the laser 31 is configured to move back and forth along the length and width of the clearance opening 51, thereby adjusting the relative position of the laser 31 in the first position 21. When different sizes and types of waveguide lenses under test are placed in the first position 21, the laser 31 can move back, forth, left, and right to adjust its position, ensuring that the laser 31 can always be adjusted to the relative position with the first coupling grating in the waveguide lens under test.

[0034] It is also worth noting that the aforementioned laser 31 can move left, right, forward, and backward in a manner that can also be achieved, but is not limited to, through a "motor + gear and rack transmission mechanism".

[0035] In one embodiment, the laser module 3 further includes a light shield 32; the light shield 32 is correspondingly disposed on the top and periphery of the laser module 3, so that only the bottom of the laser module 3 is connected to the clearance opening 51.

[0036] Specifically, in combination Figure 2 and 3 To elaborate further, the light shield 32 can be made of black opaque plastic material, and the light shield 32 can be detachably installed on the top and periphery of the laser module 3 by means of a bottom-up fitting. This allows the bottom of the laser module 3 to be connected only to the clearance opening 51, thereby protecting the laser 31 in the laser module 3 from the influence of light sources caused by the production line environment, and also preventing operators from accidentally touching the laser 31, thus avoiding affecting the detection accuracy.

[0037] In one embodiment, the side of the fixed base 5 is also provided with a plug-in port 52; the mounting fixture 2 can be at least partially inserted and fixed to the fixed base 5 through the plug-in port 52, or removed from the fixed base 5 through the plug-in port 52.

[0038] Specifically, in combination Figure 2 and 3 To explain in further detail, the insertion port 52 can be opened on one side along, but not limited to, the length of the fixed base 5, and one side of the insertion port 52 can also be connected to the clearance port 51 on the top of the fixed base 5. In this way, after the waveguide lens under test is inserted into the fixed base 5 through the insertion port 52 together with the mounting fixture 2, the mounting fixture 2 can also be moved back and forth in the insertion port 52 until the waveguide lens under test is in a suitable measurement position.

[0039] In addition, the mounting fixture 2 can be removed from the fixed base 5 together with the waveguide lens under test through the plug-in port 52.

[0040] Furthermore, multiple mounting fixtures 2 and waveguide lenses under test can be automatically inserted and removed from the fixed base 5 in sequence through the method of "robotic arm + assembly line + PLC control", thereby enabling automatic detection and judgment of the waveguide lenses under test and enabling the waveguide lens rapid detection device to realize the function of automated assembly line detection.

[0041] In one embodiment, the mounting fixture 2 is further provided with a clamping part 23 for manual or robotic gripping; when the mounting fixture 2 is inserted and fixed to the fixed base 5, the clamping part 23 is located outside the insertion port 52.

[0042] Specifically, in combination Figure 2 and 3 To explain in further detail, the clamping part 23 in the mounting fixture 2 can be correspondingly provided in one side of the mounting fixture 2 along its length. The clamping part 23 can be provided as a protruding strip, and the clamping part 23 can also have a recessed groove, recessed hole, or other structure to facilitate a more stable gripping by a human or robotic arm.

[0043] In one embodiment, the receiver 4 is fixedly connected to the top of the fixed base 5 and located above the clearance opening 51; along the light emission direction of the grating in the second position 22, the receiver 4 is inclined at an acute angle to the light emission direction.

[0044] Specifically, in combination Figure 2 and 3 To explain in further detail, the receiver 4 can be fixedly connected to the top of the fixed base 5 by means of an integral connection, and the receiver 4 can be tilted at a 45° angle to the light emission direction of the second coupling grating in the second position 22.

[0045] The receiver 4 can be configured as a receiving plate with scattering function, or as a light intensity sensing device. In this way, the receiver 4 can produce different effects according to the different intensities of the light emitted from the coupling grating in the waveguide lens under test (e.g., different intensity of light spot brightness, different intensity of photoelectric sensing value, etc.).

[0046] In one embodiment, the receiver 4 is one or more of a reflector, a silicon photovoltaic cell, or a photodiode; and when the receiver 4 includes a silicon photovoltaic cell or a photodiode, the receiver 4 is also electrically connected to a digital display for recording light intensity information.

[0047] Specifically, when receiver 4 is set as a reflector, the reflector can be, but is not limited to, a white diffuse reflector. This eliminates the need for additional electrical components, and the tester can determine whether the waveguide lens under test is a good product simply by observing the brightness of the light spot in the reflector.

[0048] When receiver 4 is set as a silicon photovoltaic cell or photodiode, a digital display meter for recording light intensity information can be used accordingly. This allows testers to determine whether the waveguide lens under test is a good product based on the specific values ​​displayed on the digital display meter. Furthermore, the digital display meter can record and statistically analyze data to better understand the overall yield rate of one or more batches of waveguide lenses under test.

[0049] In addition, this disclosure also provides a rapid detection method for waveguide lenses, applicable to the aforementioned rapid detection device for waveguide lenses, which includes the following steps: Step S1—Fix the waveguide lens to be tested onto the mounting fixture 2; Step S2—Align the laser module 3 with the coupling grating on one side of the waveguide lens under test, and align the receiver 4 with the coupling grating 3 on the other side of the waveguide lens under test. Step S3—Emit a test laser to the coupling grating on one side of the waveguide lens under test through laser module 3; Step S4—Observe and judge the light spot condition in receiver 4 using the human eye or light intensity receiving module; If receiver 4 has no light spot or the light spot intensity is lower than the preset threshold, the waveguide lens under test is determined to be a defective lens. If receiver 4 has a light spot and the intensity of the light spot is higher than the preset threshold, the waveguide lens under test is determined to be a good lens.

[0050] The specific method for calibrating the preset threshold is to test known good waveguide lenses, record the light intensity value received by the receiver as a reference value, and if the light intensity is lower than a certain preset percentage of the reference value in subsequent tests (e.g., lower than 90% or 80%), it can be judged as defective.

[0051] Specifically, in combination Figure 4 In further detail, the waveguide lens rapid testing method provided in this disclosure embodiment is applicable to the above-mentioned waveguide lens rapid testing device. It only requires the execution of the above-mentioned S1 to S4 steps to quickly determine the good condition of the waveguide lens under test. Moreover, the entire testing process does not require lens groups or optical path deflection elements. It is only necessary to align the light source with the larger area of ​​the output grating (rather than the smaller area of ​​the input grating) for testing and observation. It has the beneficial effects of simple operation steps, rapid testing process and accurate testing results.

[0052] In one possible implementation, step S3—emitting a test laser towards the coupling grating on one side of the waveguide lens under test via laser module 3—includes: The light source output port of laser module 3 is placed close to the coupling grating on one side of the waveguide lens under test, and the external ambient light of laser module 3 is shielded by a light shield. Then, a test laser with a wavelength range of 430nm~680nm is emitted into the coupling grating.

[0053] Specifically, in step S3, the light source output port of the laser module 3 is placed close to the coupling grating on one side of the waveguide lens under test, and the external ambient light of the laser module 3 is shielded by a light shield. This ensures that the test laser emitted by the laser module 3 can directly and accurately irradiate the coupling grating, and the shielding effect of the light shield can effectively isolate the influence of ambient light on the irradiation of the laser module 3.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.

[0055] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
