Description

Technical Field

[0001] This application relates to the technical field of assembly manufacturing. Specifically, it relates to a calibration device for an optical waveguide display module. Background Art

[0002] The optical display system of an AR glasses usually consists of various imaging systems and optical elements such as prisms, free-form surfaces, and optical waveguides combined. The imaging system is used to provide display content for the device. It can be a self-luminous active device, such as a light-emitting diode panel, or a liquid crystal display that requires external light source illumination, as well as a digital micromirror array and a laser beam scanner based on microelectromechanical systems, etc.

[0003] When an AR glasses uses an optical waveguide as an optical element, after the imaging system completes the imaging process, the waveguide couples light into the glass substrate and transmits the light to the front of the eyes and then releases it through the "total internal reflection" principle. In this process, the waveguide only responsible for transmitting the image and generally does not do any "work" (such as magnifying or reducing, etc.) on the image itself, and can be understood as "parallel light in, parallel light out", so it is a separate component independent of the imaging system. By adopting the above method, the imaging system can be placed beside, without blocking the line of sight and improving the weight distribution, and has broad development space.

[0004] In the current technology, when calibrating and assembling and fixing the optical waveguide element and the imaging system, generally, the relative position between the two is adjusted in the form of manual operation, with a large adjustment difficulty and a low yield rate of the product.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0027] Accordingly, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0028] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be construed as indicating or implying relative importance.

[0029] In the description of the present application, it should also be noted that unless otherwise clearly defined and limited, the terms "arranged" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0030] When the optical waveguide element is calibrated and assembled and fixed with the imaging system, generally the relative position between the two is adjusted in the form of manual operation, which is difficult to adjust, and the yield rate of the product is low. In view of the above problems, the embodiments of the present application provide the following solutions to reduce the adjustment difficulty and improve the yield rate of the product.

[0031] Please refer to Figure 1 and Figure 2 , this embodiment provides a calibration device 100 for an optical waveguide display module, including a bottom plate 110, and a first adjustment frame 120 and a second adjustment frame 130 arranged on the bottom plate 110. An installation plate 128 is arranged on the first adjustment frame 120, and a first adjustment component 140 and a positioning component 150 are respectively arranged on the installation plate 128. The first adjustment component 140 is connected to a second adjustment component 170 through a connecting piece 160; the positioning component 150 is used to fix the optical component, and the first adjustment component 140 and the second adjustment component 170 are used to jointly adjust the display component so that the display component cooperates with the optical component to form an optical waveguide display module. A detection component 180 is arranged on the second adjustment frame 130 for detecting the calibration state between the optical component and the display component.

[0032] Specifically, by means of the first adjusting frame 120 provided on the bottom plate 110 and the mounting plate 128 provided on the first adjusting frame 120, it is convenient to set the first adjusting component 140 on the mounting plate 128. The first adjusting component 140 is connected to the second adjusting component 170 through the connecting piece 160, which is beneficial to adjusting the display component fixed on the second adjusting component 170 through the first adjusting component 140 and the second adjusting component 170 to adjust the posture of the display component so that the display component is accurately aligned with the optical component.

[0033] By setting the positioning component 150 on the mounting plate 128, it is convenient to relatively fix the optical component and the mounting plate 128. In this way, when calibrating and aligning the display component and the optical component, keeping one of them in a fixed position and changing the position of the other is beneficial to simplifying the calibration difficulty and improving the calibration efficiency. During the process of calibrating the display component and the optical component, the detection component 180 is used to detect the effect on the light-emitting side of the optical component to detect the calibration state between the optical component and the display component, which is beneficial to improving the consistency of the calibration result between the optical component and the display component and improving the yield rate of calibration.

[0034] The calibration device 100 of the waveguide display module provided by the embodiment of the present application, by means of the first adjusting frame 120 provided on the bottom plate 110 and setting the mounting plate 128 on the first adjusting frame 120, it is convenient to set the first adjusting component 140 on the mounting plate 128, and the first adjusting component 140 is connected to the second adjusting component 170 through the connecting piece 160. When adjusting the display component fixed on the second adjusting component 170, the posture of the display component can be adjusted through the combination of the first adjusting component 140 and the second adjusting component 170, which is beneficial to comprehensively adjusting the posture of the display component so that there is a better calibration effect between the display component and the optical component to ensure the yield rate of assembly and fixation. In addition, the optical component is fixed on the mounting plate 128 through the positioning component 150. When adjusting the relative position between the display component and the optical component, it is beneficial to ensure that the optical component remains fixed, which is beneficial to reducing the difficulty during adjustment and alignment to improve the calibration rate. By means of the second adjusting frame 130 provided on the bottom plate 110 and setting the detection component 180 on the second adjusting frame 130, during the process of adjusting the relative position between the display component and the optical component, it is convenient to detect the calibration state between the optical component and the display component through the detection component 180, so as to adjust the display component and the optical component to the best state. By adopting the above method, the adjustment difficulty can be reduced and the yield rate of the product can be improved.

[0035] Such as Figure 1 and Figure 3As shown in the figure, the first adjustment assembly 140 includes a first slide 141 provided on the mounting plate 128 and a first slider 142 slidably connected to the first slide 141. A first adjusting member 1412 is provided on the first slide 141 to adjust the relative position between the first slide 141 and the first slider 142. A second slide 143 is provided on the first slider 142, and a second slider 144 slidably connected to the second slide 143. A second adjusting member 1432 is provided on the second slide 143 to adjust the relative position between the second slide 143 and the second slider 144. A corner seat 145 is provided on the second slider 144. A third slide 146 is provided on the corner seat 145, and a third slider 147 slidably connected to the third slide 146. A third adjusting member 1472 is provided on the third slider 147 to adjust the relative position between the third slide 146 and the third slider 147. The sliding directions of the first slider 142, the second slider 144, and the third slider 147 are perpendicular to each other in pairs, and the third slider 147 is connected to the connecting member 160.

[0036] Specifically, the first adjusting member 1412 and the second adjusting member 1432 can be in the form of screws. When it is necessary to adjust the positions of the first slider 142 and the second slider 144, by rotating the first adjusting member 1412 and the second adjusting member 1432, fine adjustment of the first slider 142 and the second slider 144 can be achieved, so as to improve the adjustment accuracy. It should be noted that the setting forms of the first adjusting member 1412, the second adjusting member 1432, and the third adjusting member 1472 can be the same or different. For example, Figure 3 the first adjusting member 1412 is rotatably connected to the first slide 141 to facilitate the abutment of the first adjusting member 1412 against the first slider 142; the second adjusting member 1432 is rotatably connected to the second slide 143 to facilitate the abutment of the second adjusting member 1432 against the second slider 144; the third adjusting member 1472 is rotatably connected to the third slider 147 to facilitate the abutment of the third adjusting member 1472 against the third slide 146. Taking the third adjusting member 1472 as an example, the third adjusting member 1472 can also be rotatably connected to the third slide 146, and the third adjusting member 1472 is threadedly connected to the third slider 147, as long as it can provide a relative force between the two to change the relative position.

[0037] Through the mutual cooperation of the first slider 142, the second slider 144, and the third slider 147, and the sliding directions of the first slider 142, the second slider 144, and the third slider 147 are perpendicular to each other in pairs, the spatial positions of the display component in the front-back, left-right, and up-down directions can be adjusted through the first adjustment assembly 140, so as to better calibrate between the display component and the optical component.

[0038] Such as Figure 4As shown in the figure, the second adjustment component 170 includes an angular rotating platform 172 disposed on the connecting member 160. The angular rotating platform 172 is connected to the positioning block 176 through a rotating platform rod 174, and the positioning block 176 is used to fix the display component.

[0039] Specifically, by providing the angular rotating platform 172 on the connecting member 160, the rotation angle of the positioning block 176 can be adjusted through the angular rotating platform 172. The angular rotating platform 172 is connected to the positioning block 176 through the rotating platform rod 174, which plays a role in connecting and transmitting torque. In this way, a specific distance is formed between the positioning block 176 and the angular rotating platform 172, facilitating the fixing of the display component to the positioning block 176 and avoiding interference in operation due to a relatively close distance between them.

[0040] As Figure 5 shown in the figure, fastening knobs 1762 are spacedly provided on the positioning block 176, and elastic members 1764 are sleeved on the fastening knobs 1762 to enable the fastening knobs 1762 to have an elastic force away from the positioning block 176.

[0041] Specifically, one end of the fastening knob 1762 in contact with the display component can be provided with threads to facilitate threaded connection with the assembly hole of the display component to achieve the required fixing relationship. When aligning the display component with the positioning block 176, to prevent the fastening knob 1762 from affecting normal disassembly and assembly, an elastic member 1764 is sleeved on the fastening knob 1762 to prevent the threaded end of the fastening knob 1762 from protruding from the positioning block 176. After the position between the display component and the positioning block 176 is determined, the display component is tightened and fixed through the fastening knob 1762. At the same time, after the fastening knob 1762 is loosened, due to the elastic force of the elastic member 1764, the fixing knob and the display component are no longer in contact, facilitating the removal of the display component. Among them, the elastic member 1764 can adopt a compression spring to achieve the required elastic force.

[0042] As Figure 5 shown in the figure, in an alternative embodiment of the present application, the angular rotating platform 172 includes a fixed seat 1742, an angle adjustment knob 1744, and a positioning knob 1746 provided on the fixed seat 1742. A worm gear and a worm that mesh with each other are provided inside the fixed seat 1742. The angle adjustment knob 1744 is connected to the worm, the positioning knob 1746 can abut against the worm, and the worm gear is connected to the rotating platform rod 174.

[0043] Specifically, in the above form, when the rotation angle adjustment knob 1744 is rotated, the worm is driven to rotate. When the worm rotates, the worm gear is driven to rotate, so that the rotary table rod 174 connected to the worm gear rotates synchronously. After adjusting to a suitable angle through the angle adjustment knob 1744, the positioning knob 1746 can be abutted against the worm to limit the rotation of the worm, so as to achieve the purpose of locking the angle rotary table 172. Among them, the rotary table rod 174 includes a connecting flange and a connecting rod connected to the connecting flange. The connection between the connecting flange and the worm gear is conducive to improving the connection stability. The connecting rod is connected to the positioning block 176, so that there is more operating space at the positioning block 176, which is convenient for operating the fastening knob 1762.

[0044] As Figure 4 and Figure 5 shown, the positioning assembly 150 includes a support angle table 152 provided on the mounting plate 128 and two positioning clips 154 spaced apart on the support angle table 152. The positioning clips 154 are rotatably connected to the support angle table 152, and are fixedly connected between the two positioning clips 154. There is an accommodating space between the positioning clip 154 and the support angle table 152, so that the optical component is fixed between the positioning clip 154 and the support angle table 152.

[0045] Specifically, the positioning clip 154 is rotatably connected to the support angle table 152, and the two positioning clips 154 are fixedly connected through a connecting plate 156. In this way, when the positioning clip 154 rotates relative to the support table, the two positioning clips 154 can rotate synchronously to improve the stability when fixing the optical component. When it is necessary to clamp and fix the optical component, first separate the positioning clip 154 from the support angle table 152 (as Figure 5 shown), place the optical component in the accommodating space, and then close the positioning clip 154 and the support angle table 152 (as Figure 4 shown). In the above form, when fixing the optical component, relative sliding between the positioning assembly 150 and the optical component can be avoided, and positioning is directly carried out by clamping, which is beneficial to avoiding scratching the surface of the optical component, and it can be ensured that the clamping is surface contact clamping rather than line contact or point contact, so that local stress on the optical component can be avoided, thereby avoiding damage to the optical component during fixing, improving the fixing effect, and ensuring the yield rate of the product.

[0046] As Figure 5 shown, a limit knob 157 is provided on the positioning clip 154, and a notch 158 is correspondingly provided on the support angle table 152, so that the limit knob 157 is clamped with the notch 158.

[0047] Specifically, the limit knob 157 can be a hand-tightening bolt. When the positioning clip 154 and the support angle platform 152 are closed, by rotating the limit knob 157, the limit knob 157 is clamped at the notch 158 of the support angle platform 152 to fix the optical component. When it is necessary to separate the positioning clip 154 from the support angle platform 152, the limit knob 157 is rotated in the reverse direction so that the limit knob 157 contacts and clamps with the notch 158 of the support angle platform 152. It can be understood that a torsion spring can also be provided at the rotating shaft of the positioning clip 154 and the support angle platform 152, so that the positioning clip 154 and the support angle platform 152 are closed by the elastic force of the torsion spring, thereby realizing the fixation of the optical component.

[0048] As Figure 2 shown, in an alternative embodiment of the present application, there is a preset angle between the mounting plate 128 and the bottom plate 110, and the optical component fixed on the positioning assembly 150 is arranged in the vertical direction.

[0049] Specifically, in the above manner, the first adjustment assembly 140 provided on the bottom plate 110 faces outward, which is convenient for the operator to perform relevant operations. And arranging the optical component in the vertical direction facilitates reducing the setting difficulty of the detection component 180 and simplifies the product structure.

[0050] As Figure 1 and Figure 2 shown, the detection component 180 includes a support arm 182 provided on the second adjustment bracket 130, and a slide rail 184 provided on the support arm 182. A slider 186 is arranged on the slide rail 184, and a camera is arranged on the slider 186, and the camera faces the optical component; the support arm 182 is slidably connected to the second adjustment bracket 130 through a guide slider 190, and a locking member 192 is arranged on the guide slider 190 to lock the guide slider 190 and the second adjustment bracket 130.

[0051] Specifically, the sliding direction of the slider 186 is perpendicular to the sliding direction of the guide slider 190, so as to facilitate adjusting the relative position between the camera and the optical component. For example, when it is necessary to adjust the camera in the vertical direction, the guide slider 190 can be slid relative to the second adjustment bracket 130 and fixed by the locking member 192. When fixing through the locking member 192, the abutting blocks on the locking member 192 can abut against the guide slider 190 and the second adjustment bracket 130 respectively, so as to keep the two locked by the extrusion force. When it is necessary to adjust the camera in the horizontal direction, the slider 186 can be slid relative to the slide rail 184. When it is necessary to relatively fix the slider 186 and the slide rail 184, a bolt can be screwed into the threaded hole on the slider 186 to achieve fixation by the bolt abutting against the slide rail 184.

[0052] AsFigure 1 and Figure 2 As shown in Figure 2 , the first adjustment bracket 120 includes a first adjustment base 122 and a first upright post 124 disposed on the first adjustment base 122, and the mounting plate 128 is disposed on the first upright post 124; the second adjustment bracket 130 includes a second adjustment base 132 and a second upright post 134 disposed on the second adjustment base 132, and the detection assembly 180 is disposed on the second upright post 134; wherein, a first slot 1222 is provided on the first adjustment base 122 to enable the first fastener 126 to pass through the first slot 1222 and be connected to the first upright post 124, and a second slot 1322 is provided on the second adjustment base 132 to enable the second fastener 136 to pass through the second slot 1322 and be connected to the second upright post 134.

[0053] Specifically, the extending directions of the first slot 1222 and the second slot 1322 are in the vertical direction. When it is necessary to adjust the heights of the first adjustment bracket 120 and the second adjustment bracket 130, only need to loosen the first fastener 126 to adjust its position in the first slot 1222 and then tighten it for fixation. At the same time, loosen the second fastener 136 to adjust its position in the second slot 1322 and then tighten it for fixation. In this way, the operator can adjust the overall heights of the first adjustment bracket 120 and the second adjustment bracket 130 according to his own height, which is convenient for operators of different heights to use in the best posture and enhances the human-machine interaction.

[0054] In addition, the first adjustment bracket 120 and the second adjustment bracket 130 are located on opposite sides of the bottom plate 110. In this way, when adjusting the first adjustment assembly 140, the second adjustment assembly 170 or the detection assembly 180 respectively, they can be misaligned with each other to avoid interfering with the required operations, thereby reducing the operation difficulty and improving the operation comfort.

[0055] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
