Description

Technical Field

[0001] This invention relates to the field of smart glasses manufacturing equipment technology, specifically to an automatic adhesive ring attaching device for the metal shielding frame of smart glasses temples. Background Technology

[0002] As a core representative of next-generation smart wearable devices, AI smart glasses integrate cutting-edge breakthroughs in multiple fields such as artificial intelligence, augmented reality, the Internet of Things, optical displays, and sensors, forming a complete technical system from hardware architecture to software ecosystem. With the maturity of eSIM independent communication, lightweight design, and edge AI large-scale models, AI smart glasses are beginning to possess independent computing capabilities, enabling multimodal interaction (voice, gestures, eye tracking) and scenario-based services. With breakthroughs in waveguide display technology, silicon carbide lenses, and spatial computing capabilities, AI smart glasses will evolve into "holographic terminals," building XR app stores and independent operating systems, becoming a core gateway connecting the physical and digital worlds.

[0003] Currently, AI smart glasses have moved beyond the "usable" stage and are evolving towards "easy to use" and "essential use." With breakthroughs in spatial computing, silicon carbide lenses, and neural interface technologies, AI smart glasses will no longer be limited to their tool attributes, but will redefine how humans perceive the world—from "looking down at their phones" to "looking up at the future." AI smart glasses are ushering in a new era of human-machine symbiosis.

[0004] Clearly, in order to provide AI smart glasses with more opportunities for communication, computing, and interaction, integrating more components into the limited frame of the glasses is the only way forward.

[0005] AI smart glasses have ample internal space in the temples, allowing for the integration of battery modules, memory, audio components, and computing modules. However, to provide effective electromagnetic shielding and protect the wearer's vision and brain health, a metal shielding cover is typically installed on the inside of the temples. A C-shaped adhesive ring is then attached between the metal shielding cover and the temple. (See [reference needed]). Figure 13 and Figure 14 Only then can the C-shaped metal shield be installed to improve the assembly stability, waterproof and moisture-proof sealing, and ensure structural strength.

[0006] However, because the metal shielding frame of the temple to which the rubber ring is to be attached has an irregular curved surface, and the rubber ring to be attached is also designed to mimic this irregular curved surface and is made of soft material, achieving precise assembly from the top, sides, and bottom in a confined space is extremely difficult. Even slight deviations in position and size will cause problems for subsequent assembly of the metal shielding, or even prevent installation, requiring rework and reattaching of the rubber ring. Currently, there are few manufacturers and production equipment for smart glasses, and the supporting automated assembly facilities are also incomplete. Therefore, there is a need to invent a dedicated rubber ring attaching device for the temples of AI smart glasses, so as to accurately position the rubber ring to be installed in a confined space and precisely press and attach the rubber ring to the outer perimeter of the metal shielding frame of the temple from the top, sides, and bottom, thereby improving the production pass rate and efficiency of AI smart glasses. Summary of the Invention

[0007] The purpose of this invention is to solve the problem of accurately positioning the rubber ring to be installed on the outer periphery of the metal shield frame on the inner side of the temple of smart glasses in a confined space, and to accurately press and attach the rubber ring, thereby greatly reducing the positional dimensional error between the rubber ring and the temple after installation, so as to improve the quality consistency of smart glasses and increase the pass rate and efficiency of AI smart glasses production.

[0008] The technical solution adopted to solve the above problems is:

[0009] An automatic adhesive ring applicator for the metal shielding cover frame of smart eyeglass temples is proposed, including...

[0010] A feed slide horizontally mounted on the worktable.

[0011] An eyeglass positioning stage is mounted on the slider of the feed slide. The eyeglass positioning stage positions and limits the left and right temples of the eyeglasses to be fitted with adhesive rings in an unfolded posture.

[0012] Used to press the inner side of the C-shaped rubber ring onto the outer support attachment assembly.

[0013] Used for pressing the C-shaped rubber ring on the top and bottom of the extruded assembly.

[0014] The eyeglass positioning platform is equipped with a positioning base, an eyeglass frame contour block, a left temple support block, and a right temple support block. Release paper adsorption positioning components are also provided on the outer side of the left and right temples where the adhesive ring is to be applied.

[0015] The eyeglass frame contour block is provided with a frame contour groove according to the outer contour surface of the eyeglass frame to be positioned, and several elastic buckles are provided around the frame contour groove to press and lock the eyeglass frame placed in the frame contour groove for precise positioning.

[0016] The left temple support block is located below the left temple, and the right temple support block is located below the right temple, positioning and supporting the left and right temples to maintain a stable posture.

[0017] Furthermore, elastic pressure blocks are provided on the inner sides of both the left and right temple support blocks. The elastic pressure blocks press the unfolded left and right temples into the contoured curved surfaces on the upper surfaces of the left and right temple support blocks, respectively, thereby completing the synchronous locking of the posture of the left and right temples.

[0018] Furthermore, temple blocks are provided on both sides of the eyeglass frame contour block and on the outer sides of the unfolded left and right temples. The temple blocks resist the outward force of the temples and help to bond the rubber ring to the metal shield frame.

[0019] The release paper adsorption and positioning assembly precisely positions the release paper with the adhesive ring to be assembled onto the outer periphery of the metal shield frame frame on the inner side of the left and right temples, where the adhesive ring is to be attached. It includes a release paper positioning seat, an upper suction adsorption block, a lower suction adsorption block, a magnetic suction block for pressing down the edge of the release paper, and a manual adjustment positioning assembly for manually and precisely positioning the upper and lower edges of the release paper onto the adsorption end faces of the upper and lower suction adsorption blocks, respectively.

[0020] The release paper positioning base is symmetrically mounted on the outside of the left and right temples. An air extraction port is provided on the outer side, and an air extraction channel is opened inside to connect the upper air extraction adsorption block and the lower air extraction adsorption block. An upper positioning groove is provided on the upper end face of the release paper positioning base, which is directly opposite the position of the upper air extraction adsorption block, and a lower positioning groove is provided on the lower end face, which is directly opposite the position of the lower air extraction adsorption block. The upper and lower air extraction adsorption blocks respectively adsorb and position the upper and lower edges of the release paper to be positioned.

[0021] The upper positioning groove has an upper air extraction port with an air extraction channel at its center. The upper air extraction port is directly connected to the adsorption chamber of the upper air extraction adsorption block in a sealed manner. The lower positioning groove has a lower air extraction port with an air extraction channel at its center. The lower air extraction port is directly connected to the adsorption chamber of the lower air extraction adsorption block in a sealed manner. The adsorption chamber is connected to several adsorption holes opened on the adsorption end face to fully adsorb and lock the lower edge of the release paper.

[0022] The manual positioning assembly includes several sets of handwheels, a rotating shaft passing through the release paper positioning seat, a positioning pin, and a return spring. The handwheels are fixed to the outer end of the rotating shaft, which is sleeved inside the release paper positioning seat. A cam disk is provided at the inner end of the rotating shaft. The cam disk pushes the flat pin head of the positioning pin, causing the positioning pin to move up and down when the rotating shaft is rotated. The return spring is sleeved on the positioning pin, which is sleeved inside the upper or lower suction block and is arranged perpendicular to the suction end face. The return spring provides a downward elastic thrust to the positioning pin.

[0023] Furthermore, when the positioning pin is exposed, it is used to pass through the positioning holes on the upper or lower edge of the release paper to perform initial positioning of the release paper. After the positioning pin is retracted, the positioning lock on the release paper can be released. After the air is drawn outward from the air extraction interface and the magnetic pressure block presses and positions the edge of the release paper, the manual adjustment positioning component can be removed, and the position lock on the release paper can still be maintained.

[0024] The external support attachment assembly is controlled by a lifting slide on the gantry frame to move vertically, and includes a positioning plate, a lifting plate, several sets of guide rod and guide sleeve assemblies, a horizontal slider slide rail assembly, a horizontal adjustment plate, and an automatic external support assembly.

[0025] The positioning plate is stably connected to the lifting slide. The lifting plate is controlled to move up and down by the guide rod and guide sleeve assembly at the four corners. A horizontal slider slide rail assembly is set between the lifting plate and the horizontal adjustment plate to finely adjust the misalignment between the horizontal adjustment plate and the lifting plate. An automatic external support assembly is set below the horizontal adjustment plate to help attach the side of the rubber ring to the inner side of the metal shield frame of the left and right temples.

[0026] The automatic external support assembly includes an external support cylinder, symmetrically arranged clamping arms, and contouring support blocks. The clamping arms are connected to the slider of the external support cylinder, and the contouring support blocks are connected to the lower outer side of the clamping arms. The contouring support blocks on both sides are provided with side contouring grooves that fit the inner side of the metal shield frame on the side facing the left temple and the right temple, so that when the release paper is supported by force, the rubber ring on the release paper is fully pressed and bonded to the inner side of the metal shield frame.

[0027] Furthermore, a pressure sensor is installed between the clamping arm and the slider of the external support cylinder to monitor the outward clamping force of the clamping arm on the temple.

[0028] Furthermore, a temperature sensor and an electric heating rod are installed inside the contour support block so that the planar rubber ring can be heated and deformed after being attached to the inner side of the metal shield frame to remove internal stress. After bonding, it can be air-cooled and maintain the curved shape and posture to maintain the adhesion after bonding.

[0029] Furthermore, a horizontal limiting block is provided on the outer side of the horizontal adjusting plate, and the horizontal limiting block is in clearance fit with the limiting groove provided on the lifting plate to limit the horizontal displacement of the horizontal adjusting block.

[0030] The extrusion bonding components are symmetrically arranged on both sides of the eyeglass positioning platform, and apply vertical pressure to the release paper on the top and bottom of the left and right temples to complete the bonding of the top and bottom of the rubber ring to the metal shield frame.

[0031] The extrusion attachment assembly includes a top extension cylinder, a support base, a vertical slider rail assembly, a vertical adjustment plate, and a clamping hot pressing assembly. The clamping hot pressing assembly includes a clamping cylinder, symmetrically arranged extrusion arms and heat-conducting blocks, as well as an upper extrusion block and a lower extrusion block.

[0032] The top extension cylinder drives the support seat to move horizontally and precisely. A vertical slider rail assembly is set between the support seat and the vertical adjustment plate to fine-tune the misalignment between the vertical adjustment plate and the support seat. The clamping cylinder is connected to the vertical adjustment plate and arranges the two clamps symmetrically. The two clamps are respectively connected to the upper extrusion arm and the lower extrusion arm. The upper extrusion arm is connected to the upper heat-conducting block for hot-pressing the rubber ring, and the lower extrusion arm is connected to the lower heat-conducting block for hot-pressing the rubber ring. The upper heat-conducting block is connected to the upper extrusion block for fitting and pressing the rubber ring, and the lower heat-conducting block is connected to the lower extrusion block for fitting and pressing the rubber ring.

[0033] Furthermore, a vertical limiting block is provided on the outer side of the vertical adjustment block, and the vertical limiting block is in clearance fit with the limiting groove provided on the support base to limit the vertical displacement of the vertical adjustment block.

[0034] Furthermore, the upper extrusion block and the lower extrusion block are respectively positioned above and below the release paper of the adhesive ring to be applied, and are provided with upper and lower contour grooves that conform to the upper and lower surfaces of the metal shield frame, so as to fully adhere the adhesive ring to the surface of the temple.

[0035] Furthermore, pressure sensors are provided between the upper jaw and the upper compression arm, and between the lower jaw and the lower compression arm, to monitor the inward compression force exerted by the compression arm on the temple.

[0036] Furthermore, temperature sensors and electric heating rods are installed in both the upper and lower heat-conducting blocks to allow the planar adhesive ring to deform under heat after being attached to the upper and lower surfaces of the metal shield frame, thereby removing internal stress. After bonding, the ring is air-cooled and maintains its curved shape, thus preserving the adhesion after bonding.

[0037] The beneficial effects of this invention are:

[0038] 1. This intelligent glasses temple metal shield frame automatic adhesive ring attaching equipment uses a glasses positioning table to position and limit the glasses frame and temple to be attached with adhesive rings. Then, the release paper adsorption positioning component first manually and then automatically positions and adsorbs the release paper with adhesive rings attached. Then, the external support attachment component and the extrusion attachment component automatically assist in attaching the inner side, top and bottom of the adhesive rings respectively. It completes the precise automatic attachment action in a narrow space, with high attachment position accuracy and high production efficiency.

[0039] 2. By setting temperature sensors and electric heating rods in the contour support block, upper heat-conducting block and lower heat-conducting block, the planar rubber ring is pressed and attached, and then deformed by heat to remove internal stress. After bonding, it is air-cooled and maintains the curved shape, thus ensuring the adhesion between the rubber ring and the metal shield frame.

[0040] 3. By setting pressure sensors between the clamping arm and the external support cylinder, between the upper jaw and the upper extrusion arm, and between the lower jaw and the lower extrusion arm, the force of each press on the release paper and even the indirect press on the metal shield frame of the temple can be precisely controlled, ensuring that the pressure of the rubber ring is moderate and the installation quality is highly consistent.

[0041] 4. The horizontal and vertical adjustment plates help to finely adjust the horizontal position when the outer support cylinder pushes the inner side of the release paper outward to adjust the force on both sides and achieve force balance; and help to finely adjust the vertical position when the clamping cylinder presses the top and bottom of the release paper inward to adjust the force on the top and bottom and achieve pressure balance, preventing excessive pressure on the temple and bending damage.

[0042] 5. After the positioning pin is extended by manually adjusting the positioning component to assist in the initial positioning of the release paper, the magnetic pressure block presses down on the upper and lower edges of the release paper to ensure the positioning accuracy of the release paper. After the positioning pin is retracted, the magnetic pressure block still maintains the magnetic clamping force, and the auxiliary adsorption hole locks the release paper on the adsorption end face to further ensure the positional accuracy of the rubber ring.

Detailed Implementation

[0059] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. For ease of description, only the parts related to the present invention are shown in the drawings, not the entire structure.

[0060] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0061] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0062] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0063] Please see Figure 1 This embodiment proposes an automatic adhesive ring 13 application device for the metal shielding cover frame of smart glasses 15 temples, including a feed slide 1 horizontally set on a workbench and a glasses positioning table 3 set on an inclined tooling table 2 on the feed slide 1.

[0064] More specifically, see Figure 8 The eyeglass positioning platform 3 positions and limits the left temple 1503 and right temple 1502 of the eyeglasses to be fitted with the adhesive ring 13 in an unfolded posture.

[0065] Especially important, see Figure 2 and Figure 3 It also includes an outer support attachment assembly 7 for pressing the inner side of the C-shaped rubber ring 13, and an extrusion attachment assembly for pressing the upper and lower surfaces of the C-shaped rubber ring 13.

[0066] See Figure 4 The eyeglass positioning platform 3 is provided with a positioning base 301, an eyeglass frame contour block 304, a left temple support block and a right temple support block 302, and release paper 14 adsorption positioning components are also provided on the outside of the left temple 1503 and right temple 1502 where the adhesive ring 13 is to be attached.

[0067] See Figure 4 The positioning base 301 is provided with torsion spring locking hooks 306 on both sides. The torsion spring locking hooks 306 are engaged and locked with the bases on both sides of the inclined tooling table 2 to ensure the stability of the eyeglass positioning table 3.

[0068] See Figure 4The eyeglass frame contour block 304 is provided with a frame contour groove according to the outer contour curved surface of the eyeglass frame 1501 to be positioned, and a number of elastic buckles 305 are provided around the frame contour groove. The elastic buckles 305 press and lock the eyeglass frame 1501 placed in the frame contour groove, accurately positioning it and ensuring that the structure of the eyeglass frame 1501 remains stable and does not deform when the rubber ring 13 is attached to the metal shield frame 1504 of the left temple 1503 and the right temple 1502.

[0069] See Figure 4 and Figure 8 The left temple support block is located below the left temple 1503, and the right temple support block 302 is located below the right temple 1502. It positions and supports the left temple 1503 and the right temple 1502, ensuring that the posture remains stable when the rubber ring 13 is attached to the metal shield frame 1504 of the left temple 1503 and the right temple 1502.

[0070] Further implementation plans are as follows, see [link / reference] Figure 4 To ensure the stability of the left temple 1503 placed on the left temple support block and the right temple 1502 placed on the right temple support block 302, elastic pressure blocks 303 are provided on the inner sides of both the left and right temple support blocks 302. The elastic pressure blocks 303 press the unfolded left temple 1503 and right temple 1502 into the contoured curved surfaces of the upper end faces of the left and right temple support blocks 302, respectively, thus achieving synchronous locking of the postures of the left and right temples 1503 and 1502.

[0071] Most importantly, refer to Figure 5 , Figure 7 and Figure 9 The eyeglass frame contour block 304 has temple blocks 3041 on both sides and on the outer sides of the unfolded left temple 1503 and right temple 1502. The temple blocks 3041 resist the force of the temples being stretched outward and help to bond the rubber ring 13 to the metal shield frame.

[0072] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 5 , Figure 6 and Figure 7The release paper 14 adsorption positioning assembly precisely positions the release paper 14, with the adhesive ring 13 to be attached, on the outer periphery of the metal shield frame 1504 on the inner side of the left temple 1503 and right temple 1502, where the adhesive ring 13 is to be attached. It includes a release paper positioning seat 307, an upper suction adsorption block 313, a lower suction adsorption block 315, an upper magnetic suction block 311 and a lower magnetic suction block 314 for pressing the edge of the release paper 14, and a manual adjustment positioning assembly for manually and precisely positioning the upper and lower edges of the release paper 14 on the adsorption end faces 3132 of the upper suction adsorption block 313 and the lower suction adsorption block 315, respectively. The upper magnetic suction block 311 and the lower magnetic suction block 314 are each provided with a permanent magnet 3111, which can be magnetically adsorbed by the upper suction adsorption block 313 and the lower suction adsorption block 315, respectively.

[0073] Further implementation plans are as follows, see [link / reference] Figure 6 and Figure 12 Two release paper positioning seats 307 are symmetrically mounted on the outer sides of the left temple 1503 and the right temple 1502. Each seat has an air extraction port 309 on its outer surface and an internal air extraction channel connecting the upper air extraction adsorption block 313 and the lower air extraction adsorption block 315. The upper end face of each release paper positioning seat 307 has an upper positioning groove facing the upper air extraction adsorption block 313, and the lower end face has a lower positioning groove facing the lower air extraction adsorption block 315. (See reference...) Figure 7 The upper suction adsorption block 313 and the lower suction adsorption block 315 respectively adsorb and position the upper edge and lower edge of the release paper 14 to be positioned.

[0074] More specifically, see Figure 10 and Figure 12 The upper positioning groove has an upper air extraction port 3071 with an air extraction channel at its center. The upper air extraction port 3071 is in a sealed connection with the adsorption cavity of the upper air extraction adsorption block 313. The lower positioning groove has a lower air extraction port with an air extraction channel at its center. The lower air extraction port is in a sealed connection with the adsorption cavity of the lower air extraction adsorption block 315. The adsorption cavity is connected to a plurality of adsorption holes 3131 opened on the adsorption end face 3132, so as to fully adsorb and lock the lower edge of the release paper 14.

[0075] As a further solution to this embodiment, see [reference]. Figure 5 , Figure 6 , Figure 11 and Figure 12 The manual positioning assembly includes four sets of handwheels 310, four rotating shafts 308 passing through the release paper positioning seat 307, four positioning pins 312, and four return springs 3082. The handwheels 310 are fixed to the outer ends of the rotating shafts 308, and the rotating shafts 308 are sleeved inside the release paper positioning seat 307. (See reference...) Figure 11A cam disk 3081 is provided at the inner end of the rotating shaft 308. The cam disk 3081 pushes the flat pin head 3121 of the positioning pin 312. When the rotating shaft 308 is rotated, the positioning pin 312 is driven to perform up and down extension and retraction. The return spring 3082 is sleeved on the positioning pin 312. The positioning pin 312 is sleeved in the upper suction adsorption block 313 or the lower suction adsorption block 315 and is arranged perpendicular to the adsorption end face 3132. The return spring 3082 provides a downward elastic thrust to the positioning pin 312.

[0076] A further implementation scheme is that when the positioning pin 312 is exposed, it is used to pass through the positioning hole 141 on the upper or lower edge of the release paper 14 to perform initial positioning of the release paper 14. After the positioning pin 312 is retracted, the positioning lock on the release paper 14 can be released. After the air is drawn outward from the air extraction port 309 and the upper magnetic suction block 311 and the lower magnetic suction block 314 press and position the edge of the release paper 14, the assistance of the manual positioning component can be removed, and the position lock on the release paper 14 can still be maintained.

[0077] Therefore, it can be seen that:

[0078] When the positioning pin 312 is extended by the manual positioning component, it can assist in the initial positioning of the release paper 14. Then, the upper magnetic pressure block 311 and the lower magnetic pressure block 314 press down on the upper and lower edges of the release paper 14 respectively to ensure the positioning accuracy of the release paper 14.

[0079] When the positioning pin 312 is retracted, the magnetic clamping block still maintains the magnetic clamping force, and the auxiliary adsorption hole 3131 locks the release paper 14 on the adsorption end face 3132, further ensuring the positional accuracy of the adhesive ring 13.

[0080] See Figure 3 The external support attachment component 7 is controlled by the lifting slide 6 on the gantry frame to lift vertically, and includes a positioning plate 702, a lifting plate 703, four sets of guide rod and guide sleeve components 701, a horizontal slider slide rail component 705, a horizontal adjustment plate 706, and an automatic external support component.

[0081] More specifically, the positioning plate 702 is stably connected to the lifting slide 6, and the lifting plate 703 is controlled to move up and down through the guide rod and guide sleeve assembly 701 at the four corners. A horizontal slider slide rail assembly 705 is provided between the lifting plate 703 and the horizontal adjustment plate 706 to finely adjust the misalignment between the horizontal adjustment plate 706 and the lifting plate 703. An automatic external support assembly is provided below the horizontal adjustment plate 706 to help attach the side of the rubber ring 13 to the inner side of the metal shield frame 1504 of the left temple 1503 and the right temple 1502.

[0082] See Figure 3The automatic external support assembly includes an external support cylinder 707, a left clamping arm 709 and a right clamping arm 711 arranged symmetrically, a left contouring support block 710 and a right contouring support block 712. The left clamping arm 709 is connected to the left slider 708 of the external support cylinder 707. The left contouring support block 710 is connected to the lower outer side of the left clamping arm 709. The right clamping arm 711 is connected to the right slider 713 of the external support cylinder 707. The right contouring support block 712 is connected to the lower outer side of the right clamping arm 711. The contouring support blocks on both sides are provided with side contouring grooves 7101 that fit the inner side of the metal shield frame 1504 on the side facing the left temple 1503 and the right temple 1502, so that when the release paper 14 is supported by force, the rubber ring 13 on the release paper 14 is fully pressed and bonded to the inner side of the metal shield frame.

[0083] Further implementation plans are as follows, see [link / reference] Figure 3 Pressure sensors 12 are provided between the left clamping arm 709 and the left slider 708 of the outer support cylinder 707, and between the right clamping arm 711 and the right slider 713 of the outer support cylinder 707, to monitor the outward clamping force of the clamping arm on the temple.

[0084] Further implementation plans are as follows, see [link / reference] Figure 3 The conformal support block is equipped with a temperature sensor 10 and an electric heating rod 11 so that the planar rubber ring 13 can be heated and deformed after being attached to the inner side of the metal shield frame 1504 to remove internal stress. After bonding, it can be air-cooled and maintain the curved shape and posture to maintain the adhesion after bonding.

[0085] Preferably, a horizontal limiting block 704 is provided on the outer side of the horizontal adjusting plate 706, and the horizontal limiting block 704 is in clearance fit with the limiting groove provided on the lifting plate 703 to limit the horizontal displacement of the horizontal adjusting block.

[0086] See Figure 1 and Figure 2 The extrusion attachment components are symmetrically arranged on both sides of the eyeglass positioning platform 3, including the left extrusion attachment component 4 and the right extrusion attachment component 8. They apply vertical pressure to the release paper 14 on the top and bottom of the left temple 1503 and the right temple 1502 to complete the attachment of the rubber ring 13 to the metal shield frame 1504 on the top and bottom.

[0087] Specifically, the left-side extrusion attachment assembly 4 includes an extension cylinder 401, a support base 402, a vertical slider rail assembly 403, a vertical adjustment plate 405, and a left-side clamping hot pressing assembly 5. The left-side clamping hot pressing assembly 5 includes a clamping cylinder 501, an upper extrusion arm 502 and a lower extrusion arm 507 arranged symmetrically, an upper heat-conducting block 503 and a lower heat-conducting block 506, as well as an upper extrusion block 504 and a lower extrusion block 505.

[0088] As a further solution to this embodiment, see [reference]. Figure 2 The top extension cylinder 401 drives the support base 402 to move horizontally and precisely. A vertical slider rail assembly 403 is set between the support base 402 and the vertical adjustment plate 405 to finely adjust the misalignment between the vertical adjustment plate 405 and the support base 402. The clamping cylinder 501 is connected to the vertical adjustment plate 405 and arranges the two clamps symmetrically. The two clamps are respectively connected to the upper extrusion arm and the lower extrusion arm, that is, the upper clamp is connected to the upper extrusion arm 502 and the lower clamp is connected to the lower extrusion arm 507. The upper extrusion arm 502 is connected to the upper heat-conducting block 503 for hot-pressing the rubber ring 13, and the lower extrusion arm 507 is connected to the lower heat-conducting block 506 for hot-pressing the rubber ring 13. The upper heat-conducting block 503 is connected to the upper extrusion block 504 for attaching and pressing the rubber ring 13, and the lower heat-conducting block 506 is connected to the lower extrusion block 505 for attaching and pressing the rubber ring 13.

[0089] A further implementation scheme is that a vertical limiting block 404 is provided on the outside of the vertical adjustment block, and the vertical limiting block 404 is in clearance fit with the limiting groove provided on the support base 402 to limit the vertical displacement of the vertical adjustment block.

[0090] A further implementation is that the upper extrusion block 504 and the lower extrusion block 505 are respectively positioned above and below the release paper 14 on which the adhesive ring 13 is to be applied, and are provided with upper contour groove 5041 and lower contour groove 5051 that fit the upper and lower surfaces of the metal shield frame 1504, so that the adhesive ring 13 is fully fitted onto the surface of the temple.

[0091] As a further embodiment, pressure sensors 12 are provided between the upper gripper and the upper compression arm 502, and between the lower gripper and the lower compression arm 507, to monitor the inward compression force of the compression arm on the temple.

[0092] As a further embodiment, temperature sensors 10 and electric heating rods 11 are provided in both the upper heat-conducting block 503 and the lower heat-conducting block 506, so that the planar rubber ring 13 can be heated and deformed after being attached to the upper and lower surfaces of the metal shield frame 1504 to remove internal stress, and can be air-cooled after bonding to maintain the curved shape and preserve the adhesion after bonding.

[0093] Specifically, in this embodiment, the smart glasses 15 are supported by an inclined fixture 2, which keeps the temples in an inclined rather than horizontal position. Correspondingly, the upper compression block 504, the lower compression block 505, and the contouring support block are respectively attached to the upper contouring groove 5041, the lower contouring groove 5051, and the side contouring groove 7101 of the metal shield frame 1504 of the temples, which are all inclined. The purpose is to decompose the pressing pressure when the rubber ring 13 on the release paper 14 is pressed in the up and down direction. Part of the pressing pressure acts in the normal direction of the temple to reduce the pressing impact, and the other part of the pressing pressure acts in the tangential direction of the temple to provide lateral pressing and bonding to the rubber ring 13, so as to ensure that the rubber ring 13 is fully bonded to the frame.
