Description

Technical Field

[0001] This invention relates to the field of smart glasses manufacturing equipment technology, specifically to a secondary hot-pressing equipment for the nose pad cover of smart glasses. Background Technology

[0002] The development of smart glasses stems from the deep integration of miniaturized hardware, augmented reality (AR), and artificial intelligence (AI). Its core lies in integrating computing units, sensors, and display modules into lightweight frames. Early devices were bulky and had limited functionality due to limitations in battery life and heat dissipation. In recent years, breakthroughs in Micro-LED and waveguide technologies have resolved the contradiction between display brightness, energy consumption, and size, achieving clear overlay of virtual and real images. Of course, the exploration of smart glasses functions has never stopped. Implanting more sensing elements into lightweight frames allows for the continuous accumulation and training of more human-computer interaction data models, contributing to the realization of more AI functions. For example, a current smart glasses design requires components such as a microphone for sound recording and an infrared camera for capturing iris movements inside the nose pads. To protect the overall appearance of the smart glasses frame, meet waterproof and moisture-proof sealing requirements, and reduce the structural weight of the frame, the common approach is to use glue to seal the nose pads, which house numerous components, with a nose pad cover to meet design, production, and performance requirements. However, the existing nose pad cover is a thin-walled curved shape. After it is attached to the perimeter of the nose pad with adhesive, the adhesive cures too slowly. This increases the risk of displacement or even twisting and deformation of the nose pad cover due to stress and tension from the liquid adhesive. This will seriously affect the product quality and appearance of smart glasses, and will also lead to poor sealing, loss of waterproof and moisture-proof performance, and damage to internal components. Summary of the Invention

[0003] The purpose of this invention is to prevent the nose pad cover from shifting or even twisting due to the stress and tension of the liquid adhesive during the tight fit of the nose pad cover to the adhesive-coated nose pad during assembly of smart glasses. This requires a device that accelerates adhesive curing and precisely controls the nose pad cover's assembly position, ensuring a tight seal between the nose pad cover and the eyeglass frame, guaranteeing the product quality and appearance of the smart glasses, and also accelerating the assembly and production efficiency of smart glasses.

[0004] The technical solution adopted to solve the above problems is:

[0005] A secondary hot-pressing device for the nose pad cover of smart glasses is proposed, including:

[0006] A feed slide is mounted on the machine frame worktable, and a magnetic suction fixture is provided on the slider of the feed slide.

[0007] A frame positioning carrier, mounted on a magnetic fixture, positions and clamps the eyeglass frame to be fitted with nose pads.

[0008] A thermosetting curing assembly that is mounted on the outside of the eyeglass frame and uses thermosetting to position the nose pad covers that are applied to the left and right nose pads.

[0009] The magnetic fixture includes a fixture table, positioning pins, and limiting strips on the front and rear sides. After the limiting strips initially limit the positioning of the mirror frame carrier, it is then positioned by passing through several positioning pin holes on the fixture table. The permanent magnets on the base of the mirror frame positioning carrier are attracted and locked together with the permanent magnets on the fixture table.

[0010] The frame positioning carrier includes a base, a support plate, a frame contour base, a pressing plate, and a locking mechanism. The base is also equipped with a temple support platform for supporting the temples of the smart glasses to be assembled. The support plate is vertically connected to the base, and the frame contour base and locking mechanism are located on the side facing the temple support platform.

[0011] The surface of the frame contour base is provided with several contour blocks for positioning the eyeglass frame to be fitted with nose pad covers, including a bridge contour block, a frame contour block, a hinge contour block, and a nose pad contour block, which respectively position the bridge, upper and lower frames, side hinges, and nose pads of the eyeglass frame. The nose pad contour block also supports the nose pad portion of the eyeglass frame to be fitted with nose pad covers.

[0012] The locking mechanism includes a hinge seat and a slot block mounted on the support plate, and an elastic latch mounted on the pressing plate. The hinge seat is movably hinged to one side of the pressing plate, and the elastic latch is mounted on the aligned side of the pressing plate. After the elastic latch engages with the slot block, the pressing plate and the support plate are locked together.

[0013] The pressing plate is equipped with elastic silicone blocks that press firmly against the upper frame, lower frame, and bridge of the positioned eyeglasses frame.

[0014] The hot-press curing assembly includes a hot-press base, a left hot-press block for pressing the left nose pad cover, a left adjustment mechanism for fine-tuning the position of the left hot-press block, and a left pressing cylinder; and a right hot-press block for pressing the right nose pad cover, a right adjustment mechanism for fine-tuning the position of the right hot-press block, and a right pressing cylinder.

[0015] The left hot-pressing block is provided with a left pressing end, and a left pressure pad is provided on the surface of the left nose pad. The left hot-pressing block is filled with an electric heating rod and a temperature sensor for heating the left pressure pad to a set temperature. The right hot-pressing block is provided with a right pressing end, and a right pressure pad is provided on the surface of the right nose pad. The right hot-pressing block is filled with an electric heating rod and a temperature sensor for heating the right pressure pad to a set temperature. The surfaces of the left and right pressure pads that are respectively attached to the left and right nose pads are provided with contoured curved surfaces to fully press and adhere the nose pads to the adhesive before curing.

[0016] Furthermore, the left pressing cylinder and the left adjusting mechanism are connected by a pressure arm. The pressure arm cooperates with the guide rod, guide sleeve, and push plate set on the hot press base to achieve linear sliding. After receiving the thrust transmitted by the left pressing cylinder, the left adjusting mechanism drives the left hot press block to apply pressure to the left nose pad cover of the eyeglass frame, and accelerates the chemical reaction of the adhesive by heating, thus speeding up the curing process. The same applies to the right side.

[0017] Furthermore, the left and right pressing cylinders are positioned and supported by a hot press base, and the left adjustment mechanism is limited by a slider rail to achieve linear sliding.

[0018] Furthermore, the left adjustment mechanism includes a heat insulation plate, a Z-axis rotating block, an X-axis rotating block, a Y-axis rotating block, and a Z-axis rotating shaft, an X-axis rotating shaft, a Y-axis rotating shaft, and a connecting piece that are sequentially fitted between the heat insulation plate, the Z-axis rotating block, the X-axis rotating block, and the Y-axis rotating block. The right adjustment mechanism is similar.

[0019] Furthermore, the heat insulation plate is tightly connected to the left hot pressing block. The center of the heat insulation plate and the Z-axis rotating block are provided with Z-axis arc grooves along the Z-axis. The Z-axis rotating shaft is held in the two Z-axis arc grooves. The outer side of the two Z-axis arc grooves is provided with screw holes. The heat insulation plate and the Z-axis rotating block are positioned by the Z-axis rotating shaft through the connector and then screwed and locked.

[0020] Furthermore, the Z-axis rotating block and the X-axis rotating block have X-axis arc grooves at the center of their contact surfaces and along the X-axis. The X-axis rotating shaft is held in the two X-axis arc grooves. The outer sides of the two X-axis arc grooves are provided with screw holes. The Z-axis rotating block and the X-axis rotating block are positioned by the X-axis rotating shaft and then screwed and locked.

[0021] Furthermore, the X-axis rotating block and the Y-axis rotating block have Y-axis arc grooves at the center of their contact surfaces and along the Y-axis. The Y-axis rotating shaft is held in the two Y-axis arc grooves. The outer sides of the two Y-axis arc grooves are provided with screw holes. The X-axis rotating block and the Y-axis rotating block are positioned by the Y-axis rotating shaft through a connector and then screwed and locked.

[0022] Furthermore, an anti-slip washer is provided on the outside of the screw hole to prevent loosening after the connector is screwed in and locked.

[0023] Furthermore, the Y-axis rotating block is connected to the pressure arm to obtain the pressing force transmitted by the left pressing cylinder.

[0024] Furthermore, a position sensor is installed on the tooling table to detect whether the mirror frame positioning carrier is properly positioned and locked in place.

[0025] The beneficial effects of this invention are:

[0026] 1. This smart glasses nose pad cover secondary hot pressing device uses a hot pressing curing component to press and hold the nose pad cover, which is bonded to the nose pad adhesive of the glasses frame, a second time. It also accelerates the chemical reaction by heating the nose pad cover, which speeds up the curing of the adhesive. This achieves the purpose of rapid bonding and curing of the nose pad cover to the nose pad of the glasses frame. It avoids the problem of the nose pad cover, which is not positioned and controlled, being displaced or even twisted and deformed due to the stress and tension of the liquid adhesive when the adhesive cures too slowly.

[0027] 2. The frame positioning carrier, which is positioned by limit strips and positioning pins, is firmly attracted and locked by magnetic fixtures, which is convenient to install and disassemble. The frame positioning carrier adopts a modular design, which can easily replace different models of smart glasses carriers to carry out secondary hot pressing and curing processes, reduce the cost of repeated equipment development, and enhance the modular advantages of the equipment.

[0028] 3. Multiple nose bridge contour blocks, frame contour blocks, hinge contour blocks, and nose pad contour blocks work together to fully position each part of the eyeglass frame, significantly improving the positioning accuracy of the hot pressing block and the nose pad cover;

[0029] 4. With the help of the adjustment mechanism that finely adjusts the position of the hot press block, the nose pad structure of different models of smart glasses can be finely adjusted. After all, it needs to be adapted to the nose bridge size of different users. Therefore, the designed adjustment mechanism can finely adjust the pressing position of the hot press block and the nose pad cover by adjusting the three-axis position without redeveloping the equipment, which has high adaptability.

[0048] Please see Figure 2 and Figure 13 This embodiment proposes a secondary hot-pressing device for nose pad covers of smart glasses, including a feed slide 1 set on the machine frame workbench, a frame positioning carrier 4 positioned and assembled on a magnetic suction fixture 2, and a hot-pressing curing component 6 set on the outside of the eyeglass frame 5 to perform hot-pressing positioning of the nose pad covers attached to the left nose pad 502 and right nose pad 501. The magnetic suction fixture 2 is set on the slider of the feed slide 1, and the frame positioning carrier 4 positions and clamps the eyeglass frame 5 to be fitted with nose pad covers.

[0049] Specifically, see Figure 3 and Figure 10The magnetic fixture 2 includes a fixture table 201, positioning pins 203, and limiting strips 3 on the front and rear sides. After the limiting strips 3 initially limit the positioning of the mirror frame positioning carrier 4, it is then positioned by passing through the shaft holes of several positioning pins 203 on the fixture table 201. The permanent magnets provided on the base 401 of the mirror frame positioning carrier 4 are attracted and locked to the permanent magnets provided on the fixture table 201. A position sensor 202 is provided on the fixture table 201 to detect whether the mirror frame positioning carrier 4 is positioned and locked in place.

[0050] See Figure 3 and Figure 4 The frame positioning carrier 4 includes a base 401, a support plate 403, a frame contour seat 404, a pressing plate 406, and a locking mechanism. The base 401 is also provided with a temple support platform 402 for supporting the temples of the smart glasses to be assembled. The support plate 403 is vertically connected to the base 401, and the frame contour seat 404 and the locking mechanism are provided on the side facing the temple support platform 402.

[0051] More specifically, see Figure 3 and Figure 9 The surface of the frame contour base 404 is provided with a plurality of contour blocks for positioning the eyeglass frame 5 to be fitted with the nose pad cover, including a nose bridge contour block, a frame contour block, a hinge contour block and a nose pad contour block 4041 arranged symmetrically on the left and right sides, respectively positioning the nose bridge 503, the upper and lower frames, the hinges on both sides and the nose pad of the eyeglass frame 5, and the nose pad contour block 4041 also supports the nose pad part of the eyeglass frame to be fitted with the nose pad cover, so as to ensure the structural stability of the nose pad part when the hot pressing block presses the nose pad cover and the eyeglass frame nose pad.

[0052] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 3 and Figure 4 The locking mechanism includes a hinge seat 405 and two slot blocks 409 disposed on the support plate 403, and two elastic buckles 408 disposed on the pressing plate 406. The hinge seat 405 is movably hinged to one side of the pressing plate 406, and the elastic buckle 408 is disposed on the opposite side of the pressing plate 406. After the two elastic buckles 408 are engaged with the corresponding two slot blocks 409, the pressing plate 406 and the support plate 403 are locked.

[0053] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 3 and Figure 4 The pressing plate 406 is provided with elastic silicone blocks 407 facing the upper frame, lower frame and nose bridge 503 of the eyeglass frame 5 after positioning. By flipping and locking the pressing plate 406, each elastic silicone block 407 is driven to position and press the upper frame, lower frame and nose bridge 503 of the eyeglass frame 5.

[0054] The particularly important technical solution is, see [reference] Figure 7 , Figure 10 , Figure 11 and Figure 12 The hot-press curing assembly 6 includes a hot-press base 607, a left hot-press block 602 for pressing the left nose pad cover, a left adjustment mechanism 604 for fine-tuning the position of the left hot-press block 602, and a left pressing cylinder 606, as well as a right hot-press block 601 for pressing the right nose pad cover 504, a right adjustment mechanism 603 for fine-tuning the position of the right hot-press block 601, and a right pressing cylinder 605.

[0055] Specifically, the left hot pressing block 602 is provided with a left pressing end 6021, and a left pressing pad 6022 is provided on the surface of the left nose pad cover. The left hot pressing block 602 is filled with an electric heating rod 6023 and a temperature sensor 6024, which are used to heat the left pressing pad 6022 to a set temperature, so as to maintain the temperature of the left pressing pad 6022 on the left nose pad cover to accelerate the chemical reaction of the adhesive and accelerate curing without damaging the appearance structure of the nose pad cover.

[0056] Similarly, on the right side, the right hot pressing block 601 is provided with a right pressing end 6011, and the right pressing end 6011 is attached to the surface of the right nose pad cover 504 with a right pressing pad 6012. The right hot pressing block 601 is filled with an electric heating rod 6023 and a temperature sensor 6024 to heat the right pressing pad 6012 to a set temperature. The left pressing pad 6022 and the right pressing pad 6012 are respectively attached to the surfaces of the left nose pad cover and the right nose pad cover 504, and both are provided with contoured curved surfaces to fully press and adhere the nose pad cover to be cured by the glue.

[0057] A further implementation plan is to take the left side as an example, see [link / reference]. Figure 11 and Figure 12 The left pressing cylinder 606 and the left adjusting mechanism 604 are connected by a pressure arm 609. The pressure arm 609 cooperates with the guide rod and guide sleeve and the push plate 608 set on the hot press base 607 to achieve linear sliding. After the left adjusting mechanism 604 receives the thrust transmitted by the left pressing cylinder 606, it drives the left hot press block 602 to apply pressure to the left nose pad cover of the eyeglass frame 5, ensuring that the left nose pad cover will not have problems such as posture displacement, twisting deformation, or poor sealing before the glue is cured.

[0058] Similarly, on the right side, the right pressing cylinder 605 and the right adjusting mechanism 603 are connected by a pressure arm 609. The pressure arm 609 cooperates with the guide rod and guide sleeve and the push plate 608 set on the hot press base 607 to achieve linear sliding. After the right adjusting mechanism 603 receives the thrust transmitted by the right pressing cylinder 605, it drives the right hot press block 601 to apply pressure to the right nose pad cover 504 of the eyeglass frame 5, ensuring that the right nose pad cover 504 will not have problems such as posture displacement, twisting deformation, or poor sealing before the glue is cured.

[0059] Further implementation plans are as follows, see [link / reference] Figure 10 The left pressing cylinder 606 and the right pressing cylinder 605 are positioned and supported by the hot press base 607, and the left adjusting mechanism 604 is limited by the slider rail to achieve linear sliding.

[0060] The particularly important implementation plan is to refer to Figure 11 and Figure 12 The left adjustment mechanism 604 includes a heat insulation plate 6041, a Z-axis rotating block 6043, an X-axis rotating block 6045, a Y-axis rotating block 6047, and a Z-axis rotating shaft 6042, an X-axis rotating shaft 6044, a Y-axis rotating shaft 6046, and an adjustment screw (not shown in the figure) sequentially fitted between the heat insulation plate 6041, the Z-axis rotating block 6043, the X-axis rotating block 6045, and the Y-axis rotating block 6047. The right adjustment mechanism 603 is similar.

[0061] Specifically, the heat insulation plate 6041 is tightly connected to the left hot pressing block 602. The center of the contact surface between the heat insulation plate 6041 and the Z-axis rotating block 6043 is provided with Z-axis arc grooves along the Z-axis. The Z-axis rotating shaft 6042 is held in the two Z-axis arc grooves. The outer side of the two Z-axis arc grooves is provided with screw holes. After adjusting the screws to position the angle between the heat insulation plate 6041 and the Z-axis rotating block 6043 with the Z-axis rotating shaft 6042 as the axis, the screws are locked.

[0062] Specifically, the Z-axis rotating block 6043 and the X-axis rotating block 6045 have X-axis arc-shaped grooves at their center and along the X-axis, and the X-axis rotating shaft 6044 is clamped in the two X-axis arc-shaped grooves. The outer sides of the two X-axis arc-shaped grooves are provided with screw holes, and the Z-axis rotating block 6043 and the X-axis rotating block 6045 are locked by screwing in the X-axis rotating shaft 6044 as the axis after the angle between them is positioned by adjusting screws.

[0063] Specifically, the X-axis rotating block 6045 and the Y-axis rotating block 6047 are provided with Y-axis arc-shaped grooves at the center of their contact surfaces and along the Y-axis. The Y-axis rotating shaft 6046 is held in the two Y-axis arc-shaped grooves. The outer sides of the two Y-axis arc-shaped grooves are provided with screw holes. The X-axis rotating block 6045 and the Y-axis rotating block 6047 are positioned by adjusting screws with the Y-axis rotating shaft 6046 as the axis and then screwed and locked.

[0064] A further implementation scheme is to provide an anti-slip washer 6048 on the outside of the screw hole to ensure that the adjusting screw does not loosen after being screwed in.

[0065] A further implementation is that the Y-axis rotating block 6047 is connected to the pressure arm 609, and the pressure arm 609 is connected to the push rod of the left pressing cylinder 606 and obtains the pressing force transmitted by the left pressing cylinder 606.

[0066] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 8 and Figure 10 The hot press base 607 is provided with a U-shaped notch to avoid the left hot press block 602 and the right hot press block 601, and a rectangular hole to avoid the pressure arm 609.

[0067] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the claims of the present invention.
