Description

Technical Field

[0001] This application relates to the field of binocular AR glasses alignment and assembly technology, and more particularly to a binocular AR glasses alignment and assembly device. Background Technology

[0002] Augmented Reality (AR) is a technology that cleverly integrates virtual information with the real world. It widely utilizes multimedia, 3D modeling, real-time tracking and registration, intelligent interaction, and sensing technologies to simulate and apply computer-generated text, images, 3D models, music, and videos to the real world. The two types of information complement each other, thus "enhancing" the real world. To ensure the realism and consistency of AR images and provide a better user experience, very high relative positional accuracy is required during assembly. Active Alignment (AA) technology uses precise automated assembly techniques and image information captured by a camera to automatically align the lens and chip in terms of focal length, optical axis, and focal plane. Compared to traditional mechanical positioning alignment, this greatly improves lens clarity, optical axis alignment accuracy, and reduces focal plane tilt, thereby significantly improving the image quality and consistency of the lens module.

[0003] However, the current traditional assembly method for AR color-combining optical engine modules is usually manual assembly, relying on the manufacturing processes and shape positioning of the lens, frame, and Micro LED chip. The quality of the finished product is largely limited by the manufacturing precision of the materials and the assembly precision of the fixture. Moreover, due to the assembly differences between the lens and the eyeglass frame, as well as the deformation of the frame itself, it is difficult to guarantee the precision and consistency of the traditional shape positioning assembly.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

A six-axis optical engine platform, an AA binocular camera assembly, a visual adhesive assembly, and an AA six-axis fixture platform are respectively installed on the top of the frame body. There are two six-axis optical engine platforms, which are evenly distributed at the left and right ends of the frame body. There are two AA binocular camera assemblies, which are installed at the left and right ends of the rear end of the top of the frame body. The visual adhesive assembly is installed at the front end of the top of the frame body. The AA six-axis fixture platform is installed at the middle of the top of the frame body.

A conduction pressing cylinder is provided on the side of the angle four-axis adjustment module, and a lighting needle mold is provided on the top of the conduction pressing cylinder. A display is provided on the angle four-axis adjustment module, and a UV lamp is provided on the display.

[0008] Preferably, the AA binocular camera assembly includes a manual six-axis fine-tuning device, on which the AA binocular camera is mounted.

[0009] Preferably, the visual dispensing assembly includes a visual dispensing movement Y-axis, a pneumatic dispensing head is provided on the visual dispensing movement Y-axis, a laser rangefinder is provided on the back of the pneumatic dispensing head, and a downward visual recognition camera assembly is provided on the visual dispensing movement Y-axis.

[0010] Preferably, the AA six-axis fixture platform includes a precision three-axis linear motor assembly, and a precision three-axis angle adjustment stage assembly is mounted on top of the precision three-axis linear motor assembly.

[0011] Preferably, an optical vision recognition camera is mounted on the top of the precision three-axis angle adjustment stage assembly, an AR glasses bracket is mounted on the top of the precision three-axis angle adjustment stage assembly, a glasses frame closing and pressing positioning fixture is mounted at the middle of the top of the precision three-axis angle adjustment stage assembly, and a display placement position is mounted on the top of the precision three-axis angle adjustment stage assembly.

[0012] Preferably, there are two of each of the above-view optical vision recognition camera, AR glasses bracket, and display placement position, and they are installed at the left and right ends of the top of the precision three-axis angle adjustment stage assembly.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art:

[0017] This application embodiment employs a combination of two sets of human-eye camera components. After calibration, these components can simulate the image seen by the human eye when actually wearing AR glasses. The clarity of the images captured by the human-eye camera is used to calculate and provide data support for the six-axis adjustment of the two sets of Micro LED chips, improving the overall yield and consistency of the equipment. Deformation caused by manufacturing errors in the glasses frame will not affect the final wearing effect. This utility model uses a six-axis design for the frame fixture platform, allowing adjustment of the relative position of the AR glasses frame to the human-eye camera. The six-axis design addresses the issue of significant deformation caused by the manufacturing process of the glasses frame, and the potential for tolerances between different batches of frames. The added angle adjustment of the fixture platform effectively compensates for these deviations, ensuring that the positions of different frames when moving to the pre-AA position are corrected. Without this position correction, the Micro LED screen chip may fail due to excessive AA correction angle caused by large deviations in the incoming frame material. The added Tilt axis effectively improves the AA success rate of the equipment and reduces the risk of excessive material rejection. Attached Figure Description

[0030] Figure 1-4 This application provides a binocular AR glasses alignment and assembly device, including a cabinet 2. A frame body 11 is housed within the cabinet 2. The top of the frame body 11 is equipped with a six-axis optical engine platform 7, an AA binocular camera assembly 8, a visual image coating assembly 9, and an AA six-axis fixture platform 10. Two six-axis optical engine platforms 7 are evenly distributed at the left and right ends of the frame body 11. Two AA binocular camera assemblies 8 are installed at the left and right ends of the rear top of the frame body 11. The visual image coating assembly 9 is installed at the front top of the frame body 11. The AA six-axis fixture platform 10 is installed at the middle of the top of the frame body 11. By employing two sets of human-eye-like camera assemblies, after calibration, it can simulate the image seen by the human eye when actually wearing AR glasses. The clarity of the image captured by the human-eye camera is used to calculate and provide data support for the six-axis adjustment of the two sets of Micro LED chips, improving the overall yield and consistency of the device. Deformation caused by processing errors in the glasses frame will not affect the final wearing effect.

[0031] The six-axis optical-mechanical platform 7 includes a three-axis linear motion module 701, on which an angle four-axis adjustment module 704 is mounted. A conduction pressing cylinder 705 is mounted on the side of the angle four-axis adjustment module 704, and a lighting needle mold 706 is mounted on the top of the conduction pressing cylinder 705. A display 703 is mounted on the angle four-axis adjustment module 704, and a UV lamp 702 is mounted on the display 703. This allows for multi-dimensional precise adjustment of the display 703 to meet different alignment requirements. The conduction pressing cylinder 705 and the lighting needle mold 706 ensure the normal operation of the display 703 and enable electrical connection with other components. The UV lamp 702 is used for curing operations. This integrated design concentrates multiple functions on one platform, improving the equipment's working efficiency and the accuracy of alignment assembly.

[0032] The AA binocular camera assembly 8 includes a manual six-axis fine-tuning device 801, on which the AA binocular camera 802 is mounted. The manual six-axis fine-tuning device 801 can finely adjust the AA binocular camera 802, allowing operators to adjust the position and angle of the camera according to the actual situation, ensuring that the camera can accurately acquire image information, providing accurate visual feedback for alignment and assembly, thereby improving the accuracy and reliability of alignment and assembly.

[0033] The visual dispensing assembly 9 includes a visual dispensing movement Y-axis 902, on which a pneumatic dispensing head 901 is mounted. A laser rangefinder 904 is mounted on the back of the pneumatic dispensing head 901. A downward-looking visual recognition camera assembly 903 is mounted on the visual dispensing movement Y-axis 902. The structural design of the visual dispensing assembly 9 allows the pneumatic dispensing head 901 to move under the drive of the visual dispensing movement Y-axis 902. The laser rangefinder 904 is used to measure distances to assist in precise control of the amount of adhesive and the dispensing position. The downward-looking visual recognition camera assembly 903 can identify the dispensing position, ensuring the accuracy of the dispensing operation, thereby ensuring that the connection between the lens and the frame is firm and meets the process requirements.

[0034] The AA six-axis fixture platform 10 includes a precision three-axis linear motor assembly 1001. A precision three-axis angle adjustment stage assembly 1002 is mounted on top of the precision three-axis linear motor assembly 1001. The precision three-axis linear motor assembly 1001 and the precision three-axis angle adjustment stage assembly 1002 work together to achieve high-precision linear motion and angle adjustment of the components placed on it. This provides a reliable motion basis for the precise alignment of the AR glasses bracket 1004 and Display703, improves the accuracy and stability of the alignment, and ensures that the assembled AR glasses meet quality standards.

[0035] The top of the precision three-axis angle adjustment stage assembly 1002 is equipped with an upper optical vision recognition camera 1003, an AR glasses bracket 1004, a frame closing and pressing positioning fixture 1006, and a display placement position 1005. The layout design of each component on the precision three-axis angle adjustment stage assembly 1002 enables the upper optical vision recognition camera 1003 to accurately monitor the positional relationship between the AR glasses bracket 1004 and the display 703. The frame closing and pressing positioning fixture 1006 is used to fix the AR glasses bracket 1004 to ensure its stability during assembly. The display placement position 1005 provides an accurate placement position for the display 703, which is beneficial to improving assembly efficiency and accuracy.

[0036] The system includes two vision recognition cameras (1003), two AR glasses brackets (1004), and two display placement positions (1005), which are installed at the left and right ends of the top of the precision three-axis angle adjustment stage assembly (1002). The vision recognition camera (1003) is located at the rear end of the AR glasses bracket (1004), and the AR glasses bracket (1004) is located at the rear end of the display placement position (1005). By clearly defining the number and installation position of each component, the system ensures that the equipment can simultaneously perform precise alignment and assembly operations on the left and right sides of the binocular AR glasses, thereby improving the equipment's working efficiency. Furthermore, this symmetrical layout helps to ensure the consistency of assembly accuracy on both sides, thus improving product quality.

[0037] The bottom of the cabinet 2 is equipped with casters 6 on all four sides. The outer surface of the casters 6 is equipped with side brakes. The casters 6 with side brakes at the bottom of the cabinet 2 facilitate the movement and handling of the equipment, improve the mobility of the equipment, and enable the equipment to be flexibly adjusted according to the needs of the production site. The side brake design ensures the stability of the equipment during operation, prevents the equipment from moving accidentally, and ensures the safe operation of the equipment.

[0038] The bottom of the cabinet 2 is connected to support legs 3 by threaded rods on all four sides. The cabinet 2 is equipped with cabinet doors 1 on all four sides. The support legs 3 are connected to the bottom of the cabinet 2 by threaded rods. The support legs 3 can be adjusted according to the flatness of the ground to ensure that the equipment is placed stably. The cabinet doors 1 protect the internal components of the equipment from dust and debris entering and affecting the normal operation of the equipment. On the other hand, they also facilitate the operator to inspect and maintain the internal parts of the equipment.

[0039] A work indicator light 4 is installed on the right side of the top of the cabinet 2. The control computer 5 is mounted on the front right side of the work indicator light 4 via a bracket. The work indicator light 4 can intuitively display the working status of the equipment, allowing operators to understand the operation of the equipment in a timely manner. The control computer 5 serves as the control core of the equipment, facilitating operators to set parameters, control operations, and process data, thereby improving the intelligence and ease of operation of the equipment.

[0040] The working principle of this invention is as follows: The eyeglass frame is fixed to the fixture platform, allowing for six-degree-of-freedom motion. Two sets of six-axis optical engine platforms 7 respectively grasp the Micro LED chips for the left and right targets. Both sets can independently perform six-degree-of-freedom X, Y, Z, Tx, Ty, and Tz movements. The chip is connected to the driver board and powered on, projecting a chart. The downward-looking visual recognition camera assembly 903 visually detects and corrects the angle of the eyeglass frame on the fixture platform above the SUT. Subsequently, the AA six-axis fixture platform 10 is moved so that the eyeglass frame moves with the fixture to the working position of the simulated AA binocular camera assembly 8. The upward-looking optical engine visual recognition camera 1003 visually detects and identifies the rotation offset of the Micro LED chips and corrects it through the adjustment device of the AA six-axis fixture platform 10. The two sets of six-axis grasping and adjusting devices are moved so that the Micro LED chips for the left and right targets... LED chips are placed in the chip pre-assembly positions on the lens frame, so that the chart projected by the chips is imaged in the human eye camera. The computer program analyzes the image information of the chart, and through a series of algorithms, outputs adjustment data to control the movement of the six-axis SUT adjustment device, adjusting the six degrees of freedom of the relative position of the chip and the lens, gradually adjusting the optical axis center, focal length, and focal plane, and finally completing AA. Finally, the visual image coating assembly 9 and UV lamp 702 assist in completing the pre-fixation of the lens and the chip.
