Technical Field

[0001] This utility model relates to the technical field of smart glasses production equipment, specifically to camera modules and bracket assembly fixtures for smart glasses. Background Technology

[0002] AR glasses, as an emerging smart electronic product, are beginning to enter people's daily lives. Due to their camera module, AR glasses have a wide range of applications. The camera module of AR glasses, as a core interactive component, provides users with an immersive augmented reality experience through real-time environmental perception and spatial computing technology. Its functional applications cover multiple fields, achieving intelligent interaction that blends the virtual and real worlds. Currently known functions include environmental perception and spatial modeling, real-time translation and information enhancement, remote collaboration and expert guidance, dynamic navigation and accessibility assistance, creative content capture and sharing, health monitoring and behavior analysis, etc.

[0003] Therefore, the camera module has a significant impact on the user experience of AR glasses. For manufacturers assembling AR smart glasses, ensuring the positional accuracy of the camera module assembly is crucial for guaranteeing product yield under mass production demands. This necessitates the design of a dedicated fixture to ensure the camera module and the camera bracket of the AR glasses frame are pre-glued together, guaranteeing high-standard positional accuracy. This serves as the foundation for the subsequent glued bonding process between the camera bracket and the AR glasses frame. Utility Model Content

[0004] The purpose of this invention is to enable high-precision bonding and assembly of the camera module and camera bracket of AR smart glasses after gluing, thereby ensuring the initial installation accuracy of the camera module and camera bracket, providing accuracy assurance for subsequent assembly, and improving the yield rate of AR smart glasses production. We have designed and proposed a jig for assembling camera modules and brackets for smart glasses.

[0005] The technical solution adopted to solve the above problems is:

[0006] A jig for assembling a camera module and bracket for smart glasses is proposed, including...

[0007] Carrier plate, which is used to support and position the fixture body;

[0008] Several sets of support modules and pressure-holding modules are used to position, fit, and maintain pressure between the camera module and the camera bracket;

[0009] The several sets of support modules and pressure-holding modules are evenly arranged on the surface of the carrier plate.

[0010] The support module includes a support base, a support frame arranged in alignment, and a lifting assembly platform. The lifting assembly platform includes a positioning platform that cooperates with the support frame through a slider rail assembly, a pressure block, and a push spring that lifts the positioning platform. The upper surface of the positioning platform is provided with a positioning groove for loading the camera module. The push spring is located between the support base and the positioning platform. The slider rail assembly limits the positioning platform to slide vertically and maintains elastic force.

[0011] The upper end face of the support frame is provided with pressure-holding positioning holes, and the outer side is provided with slots that cooperate with the pressure-holding module for clamping.

[0012] The pressure-holding module presses the camera bracket, which is placed on the dispensing camera module, downwards to ensure that the adhesive is fully bonded between the camera module and the camera bracket, and then waits for it to cure.

[0013] Furthermore, the pressure-holding module includes a pressure-holding plate, a pressure-holding block, latches positioned on both sides of the pressure-holding plate, and a pressure-holding piece positioned on the lower end face of the pressure-holding block facing the pressure-holding camera bracket. The pressure-holding plate is provided with a pressure-holding positioning pin in the pressure-holding positioning hole opened on the upper end face of the support frame to ensure accurate positioning of the pressure-holding plate and the support frame. The latches are engaged with the slots of the support frame by the locking hooks, thus completing the positioning and locking of the pressure-holding module and the support module.

[0014] Furthermore, the pressure holding block is positioned and locked with the pressure holding groove in the center of the pressure holding plate. The outer periphery of the pressure holding groove is provided with threaded holes, and the pressure holding block and the pressure holding plate are connected and locked by screws.

[0015] Furthermore, the latch and the pressure plate are movably connected by a hinge shaft. The pressure plate is provided with a spring seat, and a return spring is provided between the latch and the spring seat to ensure that the latch and the pressure plate are stably locked.

[0016] Furthermore, the lower end face of the support base is provided with several positioning pins and supporting permanent magnets. The positioning pins cooperate with several positioning holes and shaft holes provided on the carrier plate. The carrier plate is provided with permanent magnets at the positions of several supporting permanent magnets, and each support module is connected by magnetic attraction, which facilitates quick disassembly and assembly.

[0017] Furthermore, a travel limit pin is provided on the inner side of the support frame, directly opposite the slider travel position, to limit the initial height of the positioning platform by pushing the slider.

[0018] Furthermore, the pressure block is disposed on one side of the positioning groove of the camera module for pressing the camera module to be glued. The contact surface between the pressure block and the positioning table is provided with a pressure block positioning pin and a pressure block permanent magnet. The pressure block positioning pin is positioned in conjunction with the glue dispensing positioning hole shaft hole provided on the positioning table. The pressure block permanent magnet is magnetically attracted and locked with the positioning permanent magnet provided at the corresponding position on the positioning table. The pressure block is provided with a positioning pressure head facing the camera module.

[0019] Furthermore, a positioning guide post is provided on one side of the positioning groove of the camera module, and the positioning guide post is fitted into the through hole of the camera bracket to be bonded and assembled.

[0020] Furthermore, the positioning guide post and the clearance hole provided with the pressure holding plate are fitted together to ensure that the pressure holding plate can maintain pressure on the camera bracket without obstruction.

[0021] The beneficial effects of this utility model are:

[0022] This smart glasses camera module and bracket assembly fixture uses a quick-release support module to position and support the camera module to be glued. With the help of pressure blocks, the camera bracket is manually placed after glue dispensing, and then the pressure-holding module is positioned on the support module. A push spring assists in maintaining pressure, and the alignment and pressing action of the positioning platform and pressure-holding plate ensures the glue adheres fully to the contact surfaces of the camera module and camera bracket. After curing, the assembly is complete. This fixture offers high precision in glue dispensing and component assembly, ensuring the installation accuracy of the camera module and camera bracket, providing precision assurance for subsequent assembly, and improving the yield rate of AR smart glasses production.

[0037] Please see Figure 1 This embodiment proposes a camera module and bracket assembly fixture for smart glasses, including a carrier plate 1, which is used to support and position the fixture body; six sets of support modules 2 and pressure-holding modules 3 for positioning, fitting and maintaining pressure between the camera module 5 and the camera bracket 6; the support modules 2 and pressure-holding modules 3 are evenly arranged on the surface of the carrier plate 1.

[0038] It should be noted that the camera module 5 includes a camera lens 501 and a PCBA 502, and the camera bracket 6 includes a mounting panel 601, a lens slot 603 for fitting the camera lens 501, a mounting slot 604 for fitting the lens frame, and a through hole 602 required for fitting the AR smart glasses frame.

[0039] To position the camera module 5 and camera bracket 6 for precise adhesive application, the camera module 5 and camera bracket 6 are then glued together and assembled under pressure to cure the adhesion. We will continue to provide a detailed description of the technical solution for this embodiment.

[0040] See Figure 2 and Figure 4 As a further description of the technical solution of this embodiment, the support module 2 includes a support base 201, a support frame 204 arranged in alignment, and a lifting assembly platform 4. The lower end face of the support base 201 is provided with two sets of positioning pins 202 and a supporting permanent magnet 203. The positioning pins 202 engage with positioning holes and shaft holes provided on the carrier plate 1. A permanent magnet is positioned on the carrier plate 1 directly opposite the supporting permanent magnet 203, connecting each support module 2 via magnetic attraction, facilitating quick assembly and disassembly. This allows different camera modules 5 required for different models of AR glasses to be equipped with support modules 2 of different sizes, quickly connecting and engaging with the carrier plate 1.

[0041] For a further description of the technical solution in this embodiment, please refer to... Figure 3 and Figure 4The lifting assembly platform 4 includes a positioning platform 401, a pressure block 402, and a push spring 406 that supports the positioning platform 401, which cooperates with the support frame 204 via a slider and slide rail assembly 403. The slider and slide rail assembly 403 can be set on one side of the support frame 204 or both sides of the support frame 204. The upper end surface of the positioning platform 401 is provided with a positioning groove 4011 for the camera module 5. The camera module 5 to be glued is nested in the positioning groove 4011 to maintain extremely high positioning accuracy. The push spring 406 is set between the support base 201 and the positioning platform 401. The slider and slide rail assembly 403 limits the vertical sliding of the positioning platform 401 and keeps the positioning platform 401 elastically stressed. It can fully cooperate with the pressure holding module 3 to apply the pressure holding force required for the camera module 5 and camera bracket 6 that need to be glued together.

[0042] See Figure 4 and Figure 8 The support frame 204 has a pressure-holding positioning hole 2041 on its upper end surface and a slot 205 on its outer side surface that cooperates with the pressure-holding module 3 for clamping.

[0043] As an important technical feature of this embodiment, see [link / reference] Figure 2 , Figure 3 and Figure 8 The pressure holding module 3 presses down the camera bracket 6 placed on the camera module 5 after the glue has been applied, ensuring that the glue is fully bonded between the camera module 5 and the camera bracket 6, and waits for curing. The pressure holding module 3 includes a pressure holding plate 301, a pressure holding block 302, latches 304 aligned on both sides of the pressure holding plate 301, and a pressure holding piece 307 positioned on the lower end face of the pressure holding block 302 facing the pressure-holding camera bracket 6. The pressure holding plate 301 is provided with a pressure holding positioning pin 306 in the pressure holding positioning hole 2041 opened on the upper end face of the support frame 204, ensuring that the pressure holding plate 301 and the support frame 204 are accurately positioned, and the locking hook 3041 of the latch 304 locks the slot 205 of the support frame 204, thus completing the positioning and locking of the pressure holding module 3 and the support module 2.

[0044] As a further description of the technical solution in this embodiment, please refer to... Figure 2 and Figure 3 The pressure holding block 302 is positioned and locked with the pressure holding groove 3011 opened in the center of the pressure holding plate 301. The pressure holding groove 3011 is provided with a threaded hole 3021 on its outer periphery. The pressure holding block 302 and the pressure holding plate 301 are connected and locked by screws.

[0045] As can be seen, the pressure holding block 302, which is detachable and replaceable, is connected to the pressure holding groove 3011 by a connector, which means that the corresponding model of pressure holding plate 307 can be freely replaced to adapt to the assembly of various camera modules 5 and camera brackets 6 in a standardized manner.

[0046] See Figure 3 The latch 304 and the pressure plate 301 are movably connected by a hinge shaft 305. The pressure plate 301 is provided with a spring seat 3012. A return spring 303 is provided between the latch 304 and the spring seat 3012 to ensure that the latch 304 and the pressure plate 301 are stably locked together. The continuous pressure ensures that the pressure plate 307 is aligned with the positioning groove 4011 and presses the part to be assembled.

[0047] See Figure 4 As a further limitation of the technical solution of this embodiment, a travel limit pin 206 is provided on the inner side of the support frame 204, opposite to the travel position of the slider. By pushing the slider, the initial height of the positioning stage 401 is limited, ensuring the initial height of the camera module 5 to be glued in the positioning groove 4011, which facilitates accurate positioning of the glue dispensing position and the magnitude of the force applied in subsequent pressure holding.

[0048] To help camera module 5 maintain a stable posture during glue application, please refer to... Figure 4 A pressure block 402 is provided on one side of the positioning groove 4011 of the camera module 5 to press the camera module 5 to be glued. The contact surface between the pressure block 402 and the positioning table 401 is provided with a pressure block positioning pin 4021 and a pressure block permanent magnet 405. The pressure block positioning pin 4021 is positioned in conjunction with the axial hole of the glue dispensing positioning hole 4013 provided on the positioning table 401. The pressure block permanent magnet 405 is magnetically attracted and locked with the positioning permanent magnet 404 provided at the corresponding position on the positioning table 401. A positioning pressure head 4022 is provided at the position where the pressure block 402 faces the camera module 5 and is tightly pressed together.

[0049] See Figure 5 and Figure 9 The positioning guide post 4012 is provided on one side of the positioning groove 4011 of the camera module 5. The positioning guide post 4012 is fitted through the through hole 602 provided on the camera bracket 6 to be bonded and assembled, and the positioning guide post 4012 is fitted through the clearance hole 3071 provided on the pressure plate 307 to ensure that the pressure plate 307 can maintain pressure on the camera bracket 6 without obstruction.

[0050] Based on the above description of the technical solutions in the embodiments, the following demonstrates the assembly process performed by this fixture:

[0051] First, remove the pressure holding module 3 and the pressure block 402. Place the camera module 5 to be glued into the positioning groove 4011 on the upper surface of the positioning table 401, and then place the pressure block 402. Position and lock the pressure block 402 with the pressure block positioning pin 4021 and the pressure block permanent magnet 405. Of course, the positioning pressure head 4022 at the front end of the positioned pressure block 402 presses against the PCBA 502 of the camera module 5 to stabilize the glue dispensing posture. After the automatic glue dispensing machine on the production line dispenses glue around the camera lens 501 of the camera module 5, automatically or manually place the camera bracket 6 to maintain... The mounting slot 604 of the camera bracket 6 is nested and fitted around the camera lens 501, allowing the camera lens 501 to pass through the lens slot and the through hole 602 of the camera bracket 6 to pass through the positioning guide post 4012, ensuring that the two parts assembled by adhesive bonding are fully positioned by the positioning guide post 4012; then the pressure holding module 3 and the support module 2 are positioned and locked, and with the pressure holding plate 307 pressing down on the camera bracket 6, the push spring 406 under the positioning table 401 pushes upward to maintain the elastic pressure. After the adhesive cures, the precise assembly of the camera module 5 and the camera bracket 6 is completed.

[0052] It should be noted that all parts of this fixture that come into direct contact with the camera module 5 and the camera bracket 6 are made of anti-static hard silicone to prevent scratches on the outer surfaces of the camera module 5 and the camera bracket 6 and to prevent electrostatic interference.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. For those skilled in the art, various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
