Description

Technical Field

[0001] The utility model belongs to the technical field of AR diffraction optical waveguides, and in particular relates to auxiliary equipment for testing the performance of finished waveguide products. Background Art

[0002] With the development of information technology, augmented reality (AR) technology has become increasingly mature and is being used more and more widely in education, medical care, entertainment, industry and other industries.

[0003] Augmented reality technology can be implemented through a variety of hardware platforms, the most immersive of which is wearable augmented reality devices, namely AR glasses. Currently, the more mature AR glasses technology solutions are mainly divided into prism solutions, birdbath solutions, free-form surface solutions, off-axis holographic lens solutions, and diffractive waveguide solutions. Depending on the grating type, diffractive waveguides can be divided into two categories: surface relief grating waveguides and volume holographic grating waveguides.

[0004] Taking a surface relief grating waveguide as an example, the preparation process of the prior art is generally as follows:

[0005] 1. Prepare an imprint master with a preset grating structure.

[0006] 2. The grating structure of the imprint master is transferred to the soft film through the nanoimprint process to obtain the inverse structure of the grating structure on the soft film.

[0007] Specifically, the embossing glue is evenly spin-coated on the embossing master, the soft film substrate is bonded to the embossing master, and pressure is applied to fill the embossing glue into the grating structure of the embossing master, and the inverse structure of the grating structure is obtained on the embossing glue. The embossing glue with the inverse structure of the grating structure is transferred to the soft film substrate by ultraviolet light curing and demolding, thereby obtaining a soft film with the inverse structure of the grating structure.

[0008] 3. The inverse structure of the grating structure on the soft film is transferred to the glass wafer through the nanoimprint process to obtain a glass wafer with a grating structure, thereby obtaining a surface relief grating waveguide.

[0009] Specifically, a tackifier and product glue are spin-coated on a glass wafer in sequence, a soft film with a grating structure inverse structure is bonded to the product glue on the glass wafer, pressure is applied to fill the product glue into the grating structure inverse structure of the soft film, a grating structure is obtained on the product glue, and ultraviolet light curing and demolding are used to separate the soft film with a grating structure inverse structure from the product glue with a grating structure to obtain a glass wafer with a grating structure, thereby obtaining a finished waveguide product - a surface relief grating waveguide.

[0010] In order to ensure that the optical performance of the finished waveguide product meets the set requirements, the finished waveguide product needs to be placed on a corresponding auxiliary device, and then an optical performance testing device is used to perform an optical performance test on the finished waveguide product placed on the auxiliary device.

[0011] In the existing process of using optical performance testing equipment to perform optical performance testing on a finished waveguide product arranged on an auxiliary device, in order to enable the optical performance testing equipment to receive the outcoupled light of the finished waveguide product, it is necessary to manually adjust the relative positions of the optical performance testing equipment and / or the auxiliary device, which greatly reduces the testing efficiency of the optical performance testing equipment in performing optical performance testing on the finished waveguide product arranged on the auxiliary device.

Those skilled in the art should understand that any description of a particular embodiment herein may be substituted, combined, or otherwise combined with the description of one or more other embodiments.

[0069] In the description herein, “a plurality of” means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0070] like Figure 1-Figure 2 As shown, the utility model provides a waveguide finished product performance test auxiliary equipment, including a support component, a fixing plate 1, a controller and a driving component 20.

[0071] The inner edge of the fixing plate 1 is connected to the outer edge of the supporting assembly, and a clamping hole 2 is provided inside the fixing plate 1 (such as Figure 4 As shown), the snap-in hole 2 corresponds to the outer contour of the waveguide product, and the snap-in hole in the fixing plate 1 snaps in with the contour side wall of the waveguide product 3 (as shown Figure 3 shown).

[0072] The support assembly is provided with an optomechanical module fixing hole and a test hole. The optomechanical module is installed in the optomechanical module fixing hole, and the test hole is used to test the optical performance of the outcoupling grating area of ​​the finished waveguide product. The test hole is connected to the clamping hole.

[0073] The supporting assembly provides positioning support for the local position of the finished waveguide product.

[0074] Illustratively, the support assembly may include a base plate 4 and a support plate 5 .

[0075] The inner edge of the support plate 5 is connected to the outer edge of the bottom plate 4, and the outer edge of the support plate 5 is connected to the inner edge of the fixing plate 1. For example, the bottom plate, the support plate and the fixing plate can be provided with fixing holes 6 at the edge of the plate surface (such as Figure 4-Figure 6 As shown in FIG, the bottom plate, the support plate, and the fixing plate are connected together through the fixing holes using bolts, nuts, and other connectors. The outer side of the bottom plate is the side of the bottom plate away from the optical performance test equipment.

[0076] The bottom plate 4 has a first through hole 7 and a second through hole 8 (such as Figure 5 As shown), a third through hole 9 and a fourth through hole 10 are provided inside the support plate 5 (as shown Figure 6The first through hole 7 is connected to the third through hole 9 to form the above-mentioned test hole, and the second through hole 8 is connected to the fourth through hole 10 to form the above-mentioned optical-mechanical module fixing hole.

[0077] The aperture size of the third through hole is preferably smaller than the aperture size of the first through hole. The aperture size of the fourth through hole can be comparable to the aperture size of the second through hole.

[0078] There is no specific limitation on the shapes of the first through hole, the second through hole, the third through hole and the fourth through hole. As shown in the figure, the shapes of the first through hole, the second through hole, the third through hole and the fourth through hole are close to rectangles.

[0079] The support plate is provided with positioning support portions, which are capable of positioning and supporting local locations of finished waveguides having different profiles. For example, the support plate may be provided with multiple positioning support portions spaced apart around the third through hole, and these multiple positioning support portions may position and support local locations of finished waveguides having different profiles. It should be noted that the local locations of the finished waveguide here refer to local locations within the waveguide substrate region of the finished waveguide, excluding the incoupling grating region and the outcoupling grating region.

[0080] In a more specific example, the positioning support portion may include a first positioning support portion and a second positioning support portion.

[0081] For example, the support plate extends from one side wall of the third through hole toward the inside of the third through hole to form a first positioning support portion. Figure 6 As shown, the support plate 5 extends toward the inside of the third through hole 9 on a side wall of the third through hole 9 close to the fourth through hole 10 to form a first positioning support portion 11 .

[0082] The support plate is provided with a support rod inside the third through hole, and the support rod can be provided in different areas inside the third through hole. Specifically, the support plate is provided with a plurality of connection holes at intervals around the edge of the third through hole, and the ends of the support rod are detachably connected to the connection holes at different positions, so that the support rod can be provided in different areas inside the third through hole. Figure 6 As shown, the support plate 5 is provided with a plurality of first connection holes 13 at intervals on the edge position near the top end of the third through hole 9, and the support plate 5 is provided with a plurality of second connection holes 14 at intervals on the edge position near the bottom end of the third through hole 9. The two ends of the support rod are detachably connected to the first connection holes and the second connection holes at different positions, respectively, so that the support rod can be set in different areas inside the third through hole.

[0083] The contact surface between the support rod 12 and the finished waveguide forms a second positioning support portion 15 (eg Figure 7 shown).

[0084] The first positioning support portion and the second positioning support portion are used to position and support the local positions of the finished waveguide products with different outer contours.

[0085] For example, Figure 8-Figure 9 As shown, the optical engine module may include an optical engine 16, a cover plate 17, and a positioning plate 18. The optical engine 16 has a light emitting port, and the positioning plate 18 is provided with an optical engine positioning hole 19.

[0086] The cover plate 17 is connected to the positioning plate 18. For example, the cover plate 17 and the positioning plate 18 are respectively provided with fixing holes 6 (such as Figure 9 As shown), bolts, nuts and other connectors are used to connect the cover plate and the positioning plate through the fixing holes, so that the light output port of the optical machine is clamped in the optical machine positioning hole.

[0087] The cover is connected to the support assembly. For example, taking the support assembly including the above-mentioned base plate and support plate as an example, a fixing hole 6 is provided at the edge of the inner side of the base plate 4 near the second through hole 8 (such as Figure 5 As shown), the cover plate 17 is provided with a fixing hole 6 (as shown Figure 8 As shown in the figure, bolts, nuts and other connectors are used to connect the bottom plate and the cover plate through the fixing holes, so that the positioning plate is set in the fixing hole of the optical machine module, so that the outgoing light of the optical machine can be emitted through the light exit port and then pass through the optical machine positioning hole located in the fixing hole of the optical machine module to be projected onto the coupling grating area of ​​the finished waveguide product.

[0088] The utility model provides auxiliary equipment for testing the performance of finished waveguide products. The support assembly can provide local positioning support for finished waveguide products with different external profiles. It only requires changing the morphological features of the clamping holes in the fixing plate according to the external profile of the finished waveguide product, thereby greatly reducing the efficiency of testing the optical performance of the finished waveguide product and improving the cost of testing the optical performance of the finished waveguide product.

[0089] The controller is connected to the drive assembly, which is in turn connected to the support assembly. During optical performance testing of a finished waveguide product mounted on the finished waveguide product performance testing auxiliary equipment using optical performance testing equipment, the controller controls the drive assembly to rotate the support assembly, thereby rotating the finished waveguide product performance testing auxiliary equipment. This adjusts the relative positions of the optical performance testing equipment and the finished waveguide product performance testing auxiliary equipment, enabling the optical performance testing equipment to quickly and accurately receive outcoupled light from the finished waveguide product, thereby significantly improving the efficiency of the optical performance testing equipment in performing optical performance testing on the finished waveguide product mounted on the finished waveguide product performance testing auxiliary equipment.

[0090] The controller can be made of existing components.

[0091] For example, Figure 10-11As shown, the drive assembly may include a bearing seat 20-1, a motor 20-2, a connecting shaft 20-3, a first bearing 20-4, a second bearing 20-5, a first finger ring 20-6, a second finger ring 20-7, and an adapter seat 20-8.

[0092] A first bearing 20-4 and a second bearing 20-5 are respectively provided on both side edges of the inner side of the bearing seat 20-1.

[0093] The first bearing 20-4 is fixed to the bearing seat 20-1 through a first positioning ring 20-6, and the second bearing 20-5 is fixed to the bearing seat 20-1 through a second positioning ring 20-7.

[0094] The motor 20-2 is connected to the controller, one end of the output shaft of the motor 20-2 is connected to one end of the connecting shaft 20-3, and the other end of the connecting shaft 20-3 passes through the first bearing 20-4 and the second bearing 20-5 in the bearing seat 20-1 and is connected to the adapter seat 20-8.

[0095] The adapter is connected to the support assembly. Take the support assembly including the above-mentioned base plate and support plate as an example. Figure 5 As shown, an adapter plate 4 - 1 integrally formed with the bottom plate 4 is provided on the side of the bottom plate 4 , and the bottom plate 4 is connected to the adapter seat 20 - 8 through the adapter plate 4 - 1 .

[0096] The controller controls the connection shaft connected to the motor to rotate, thereby driving the adapter to rotate, and further driving the base plate connected to the adapter in the support assembly to rotate, thereby driving the support assembly to rotate.

[0097] As a preferred embodiment,

[0098] like Figure 10-11 As shown, the above-mentioned drive assembly can also include a fixing frame 20-9, which passes through the body of the motor 20-2 and is connected to the bearing seat 20-1, thereby greatly improving the connection stability between the motor itself and the bearing seat during the rotation of the motor.

[0099] The driving assembly may further include a rotating baffle 20-10 and a fastener 20-11. The rotating baffle 20-10 is connected to the bearing seat 20-1 via the fastener 20-11, and the rotating baffle 20-10 limits the rotation angle of the supporting assembly driven by the motor.

[0100] Taking the supporting assembly including the above-mentioned bottom plate and supporting plate, the side of the bottom plate 4 is provided with an adapter plate 4-1 integrally formed with the bottom plate 4 as an example, a protrusion 4-2 (such as Figure 5 As shown), the rotating baffle 20-10 is provided with a notch 20-12 near the raised portion (as shown Figure 11As shown in the figure, when the controller controls the connecting shaft connected to the motor to rotate and drive the adapter seat to rotate, and then drives the base plate connected to the adapter seat to rotate, the raised portion of the adapter plate integrally formed with the base plate will be limited by the rotation stroke of the notch portion in the rotating baffle during the rotation process, so that the raised portion of the adapter plate integrally formed with the base plate can only rotate within the limited rotation angle range of the notch portion in the rotating baffle during the rotation process, thereby enabling the optical performance testing equipment to receive the coupled-out light of the waveguide product more quickly and accurately.

[0101] As a preferred embodiment, the waveguide finished product performance testing auxiliary equipment of the present invention further includes a sliding component.

[0102] like Figure 12 As shown, the sliding assembly 21 example includes a slider 21-1 and a slide rail 21-2, wherein one end of the slider 21-1 is connected to the slide rail 21-2, and the other end of the slider 21-1 is connected to the support assembly. For example, taking the above-mentioned driving assembly including a bearing seat as an example, the other end of the slider is connected to the bearing seat, thereby realizing connection with the support assembly.

[0103] The sliding assembly can drive the supporting assembly to move up and down, so that when the optical performance testing equipment is used to perform an optical performance test on the waveguide finished product set on the waveguide finished product performance testing auxiliary equipment, the optical performance testing equipment can quickly lock the eye box range of the waveguide finished product.

[0104] The process of using the waveguide finished product performance test auxiliary equipment of the present invention to test the optical performance of the waveguide finished product is as follows:

[0105] 1. Assemble the auxiliary equipment for waveguide finished product performance testing according to the above assembly relationship.

[0106] Taking the positioning support portion of the support plate including the first positioning support portion and the second positioning support portion as an example, the position relationship of the support rod in the third through hole of the support plate is positioned and set according to the outer contour of the finished waveguide to be tested.

[0107] 2. Fix the waveguide finished product performance test auxiliary equipment to the front end of the optical performance test equipment, wherein the inner side of the bottom plate is close to the front end of the optical performance test equipment.

[0108] 3. Place the finished waveguide to be tested in the snap-in hole in the fixing plate so that the snap-in hole in the fixing plate snaps onto the contour side wall of the finished waveguide to be tested.

[0109] 4. Start the optical machine. The outgoing light of the optical machine is projected onto the coupling grating area of ​​the waveguide product to be tested. The light is received by the coupling grating area of ​​the waveguide product to be tested and propagates through total reflection of the waveguide substrate of the waveguide product to be tested to reach the coupling grating area of ​​the waveguide product to be tested.

[0110] 5. The controller controls the driving assembly to drive the supporting assembly to rotate and then drives the waveguide finished product performance test auxiliary equipment to rotate, so that the optical performance test equipment can accurately receive and test the outcoupled light of the waveguide finished product.

[0111] The sliding assembly drives the supporting assembly to move up and down, so that the optical performance testing equipment can quickly lock the eye box range of the finished waveguide product.

[0112] 6. The optical performance testing equipment tests the outcoupled light in the outcoupled grating area of ​​the finished waveguide to be tested and outputs the test results.

[0113] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the same. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field can still modify or replace the specific implementation methods of the present invention.
