Description

Technical Field

[0001] This utility model relates to the field of eyeglass assembly technology, specifically an active alignment fixture for AR eyeglass lens modules. Background Technology

[0002] AR glasses, or Augmented Reality glasses, are smart wearable devices that combine the real and virtual worlds by using technologies such as augmented reality, audio-visual fusion, and waveguide lenses to collect data from real-world scenes through cameras and sensors. They work by projecting computer-generated images, videos, or other virtual information directly onto the user's eyes through a built-in miniature projector or transparent display, merging it with real-world vision and achieving virtual-real fusion and interaction through sensing and computation. AR glasses are considered a major form of AR technology and are promising for applications such as school teaching, museum visits, remote equipment maintenance in factories, and clinical diagnosis in hospitals. The manufacturing process of AR glasses involves assembling lenses onto a frame.

[0003] A prior art lens assembly device, with application number 202421241244.4, includes a housing, a lens limiting mechanism, a leveling mechanism, and a lens barrel fixing mechanism, all of which are mounted on the housing. While this lens assembly device can improve the imaging quality of optical lenses, simplify the assembly process, and increase production efficiency and product yield, it is inconvenient to align AR glasses lenses vertically with the eyeglass frame and to adjust the assembly angle of the positioned lenses, thus affecting assembly efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an active alignment fixture for AR glasses lens modules, in order to solve the problems in the prior art where it is inconvenient to align AR glasses lenses vertically with the eyeglass frame and it is also inconvenient to adjust the assembly angle of the lenses after positioning, thus affecting the assembly efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an active alignment fixture for an AR glasses lens module, comprising a fixture base, a first slider mounted on the upper side of one end of the fixture base via a first lead screw, a vertical plate mounted on the upper side of the first slider, a second slider mounted on the side wall of the vertical plate via a second lead screw, a transverse support mounted on one side of the second slider, a third slider mounted inside the transverse support via a third lead screw, a positioning seat rotatably mounted on the lower end of the third slider via a lower support and a connecting shaft, a motor being driven to one end of the connecting shaft via a gear set, a positioning disk mounted on the lower end of the positioning seat, and multiple lens suction cups mounted on the lower side of the positioning disk via a lifting adjustment mechanism.

[0006] Furthermore, the gear set is a reduction gear, and the motor is fixedly mounted on the outer wall of the lower bracket via a base.

[0007] Furthermore, the first lead screw is configured as an X-axis lead screw, the second lead screw is configured as a Z-axis lead screw, and the third lead screw is configured as a Y-axis lead screw.

[0008] Furthermore, a mirror frame positioning mechanism is provided on the upper side of one end of the tooling base. The mirror frame positioning mechanism includes a fixed clamping plate and a movable clamping plate. The movable clamping plate is installed on the tooling base by a cylinder.

[0009] Furthermore, both the fixed clamping plate and the movable clamping plate are provided with positioning grooves on one side, and the inner wall of the positioning grooves is provided with protective pads.

[0010] Furthermore, the lifting adjustment mechanism includes a lifting bracket that is slidably inserted into the limiting sliding hole inside the positioning plate, the lens suction cup is fixedly installed at the lower end of the lifting bracket, and the upper end of the lifting bracket is threadedly connected to the height adjustment screw on the upper part of the positioning plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes multiple lens suction cups provided under the positioning plate to hold and fix one side of the AR glasses lens. Then, the fixed AR glasses lens is moved and adjusted along the X-axis and Y-axis by the first lead screw and the third lead screw to facilitate the vertical alignment of the AR glasses lens with the glasses frame. Then, the AR glasses lens is driven to move down by the second lead screw for assembly.

[0013] 2. This utility model utilizes a positioning seat that is rotatably mounted on a third slider via a lower bracket and a connecting shaft. One end of the connecting shaft is connected to a motor via a gear set, allowing the motor and gear set to drive the connecting shaft to rotate in both directions. This adjusts the longitudinal angle of the positioning disc, facilitating the alignment of AR glasses lenses with different tilt angles after positioning.

[0014] 3. This utility model includes a lifting bracket that is slidably inserted into the limiting sliding hole inside the positioning plate through a lifting adjustment mechanism. The lens suction cup is fixedly installed at the lower end of the lifting bracket, and the upper end of the lifting bracket is threadedly connected to the height adjustment screw on the positioning plate. This allows the lifting bracket to be moved and adjusted by rotating the adjustment screw, thereby adjusting the distance between the lens suction cup and the positioning plate. This makes it easier for multiple lens suction cups to be held and fixed on one side of the curved lens, which helps to improve the stability of the lens suction cup holding and fixing.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3In this embodiment of the invention, an active alignment fixture for an AR glasses lens module includes a fixture base 1 and a PLC control cabinet for overall operation. A first slider 3 is mounted on the upper side of one end of the fixture base 1 via a first lead screw 4. A vertical plate 2 is mounted on the upper side of the first slider 3. A second slider 6 is mounted on the side wall of the vertical plate 2 via a second lead screw 5. A horizontal support 7 is mounted on one side of the second slider 6. A third slider 9 is mounted inside the horizontal support 7 via a third lead screw 8. The first lead screw 4 is configured as an X-axis lead screw, the second lead screw 5 is configured as a Z-axis lead screw, and the third lead screw 8 is configured as an X-axis lead screw. Using a Y-axis lead screw, the lower end of the third slider 9 is rotatably provided with a positioning seat 15 via a lower bracket 10 and a connecting shaft 11. The lower end of the positioning seat 15 is provided with a positioning disk 14. The lower side of the positioning disk 14 is provided with multiple lens suction cups 22 via a lifting adjustment mechanism, which are used to hold and fix one side of the AR glasses lens. Then, the fixed AR glasses lens is moved and adjusted along the X-axis and Y-axis by the first lead screw 4 and the third lead screw 8 to facilitate the alignment of the AR glasses lens with the glasses frame. Then, the AR glasses lens is driven to move down by the second lead screw 5 for assembly.

[0022] like Figure 1 and Figure 2 As shown, in order to align AR glasses lenses with different tilt angles, a motor 13 is also connected to one end of the connecting shaft 11 via a gear set 12. The gear set 12 is a reduction gear, and the motor 13 is fixedly mounted on the outer wall of the lower bracket 10 via a base. The motor 13 is a self-locking motor, so that the longitudinal angle of the positioning disk 14 can be adjusted by driving the connecting shaft 11 to rotate forward and backward through the motor 13 and the gear set 12, which facilitates the alignment operation after positioning AR glasses lenses with different tilt angles.

[0023] like Figure 1 and Figure 2 As shown, in order to clamp and fix the frame to be assembled, a frame positioning mechanism is provided on the upper side of one end of the tooling base 1.

[0024] like Figure 1 and Figure 3As shown, the lifting adjustment mechanism also includes a lifting bracket 20 that is slidably inserted into the limiting sliding hole 16 inside the positioning disk 14. The lens suction cup 22 is fixedly installed at the lower end of the lifting bracket 20, and the upper end of the lifting bracket 20 is threadedly connected to the height adjustment screw 21 on the upper part of the positioning disk 14. This allows the lifting bracket 20 to be moved and adjusted by rotating the height adjustment screw 21, thereby adjusting the distance between the lens suction cup 22 and the positioning disk 14. This makes it easier for multiple lens suction cups to be held and fixed on one side of the curved lens, which helps to improve the stability of the lens suction cup holding and fixing.

[0025] The working principle and usage process of this utility model are as follows: In use, the frame positioning mechanism is used to clamp and fix the frame to be assembled laterally. Then, multiple lens suction cups 22 provided under the positioning plate 14 are used to hold and fix one side of the AR glasses lens. Then, the fixed AR glasses lens is moved and adjusted along the X-axis and Y-axis by the first lead screw 4 and the third lead screw 8 to make it easy to align the AR glasses lens vertically with the glasses frame. Then, the AR glasses lens is driven to move down by the second lead screw 5 for assembly.
