Description

[0002] With the deep integration of AI technology and consumer electronics products, intelligent glasses as the "next generation of personal terminal" accelerate from concept to commercialization.

[0003] The core characteristics of intelligent glasses "high performance + small size + surface wearing" make it face severe thermal management challenges - the local temperature rise generated by the high-intensity operation of chips, optical modules, batteries and memories in the extremely small space directly affects the device reliability and user wearing comfort, and becomes the core bottleneck restricting the industrial scale landing.

[0004] In the design of the existing multiple intelligent glasses, a larger storage space is designed at the left and right hinges of the glasses frame, and the chips, memories and batteries are respectively packaged in the left and right hinge frames. In addition, the optical module, transceiver sound module and sensor module designed in the glasses frame all greatly occupy the space in the hinge frame, which will cause the heat generated by multiple components to gather and the temperature to rise sharply. If there is no effective heat dissipation element to assist in accelerating heat dissipation, it will cause multiple components to be heated and aged, and even be damaged by heat melting. And the hinge frame is close to the face and eyes, which is a key safety hazard.

[0005] Therefore, it is necessary to design a good thermal management scheme for intelligent glasses, which must rely on new thin and flexible heat dissipation materials and miniaturized structures to achieve efficient heat conduction and dissipation in limited space. For example: paste passive heat conduction graphite film on the inner wall of the hinge frame to quickly absorb the heat generated by the heat generating components packaged inside, and to quickly conduct the accumulated heat to the non-contact area in the form of increasing the heat dissipation area, so as to avoid direct contact between the heat source and the skin of the face causing burns.

[0006] Therefore, in the production process of intelligent glasses, precise pasting of the heat dissipation sheet on the inner wall of the hinge frame is an important production link, and it is necessary to design a special, automated and high-precision heat dissipation sheet mounting equipment to realize efficient production and improve the heat dissipation yield.

[0052] Please see Figure 1 This embodiment proposes a hot-pressing patch device for the left and right hinge frames of smart glasses, including a feed slide 6 set on a worktable. A magnetic suction fixture 601 is set on the feed slide 6. A limiting strip 602 and a positioning pin (not shown in the figure) are set on the upper end face of the magnetic suction fixture 601. The frame carrier 5, which is positioned by the limiting strip 602 and the positioning pin, is firmly attracted and locked by the magnetic suction fixture 601, which is convenient for assembly and disassembly.

[0053] It also includes a frame carrier 5 that positions and locks the eyeglass frame 7 to which the heat sink 9 is to be applied, and the frame carrier 5 positions, presses and locks it. The frame carrier 5 is provided with a frame contouring seat 501 for positioning the eyeglass frame 7. The frame contouring seat 501 has contouring grooves for positioning the left and right frames of the eyeglass frame 7. Four spring-assisted elastic pressure blocks 506 are provided around the contouring grooves to press the eyeglass frame 7 positioned in the contouring grooves.

[0054] Specifically, the positioning pin is fitted with a bushing (not shown in the figure) on the base of the frame carrier 5 to be assembled, and then locked in place by permanent magnets arranged on each other.

[0055] The system includes a Z-axis lifting slide 2 fixed by a gantry frame, a hinge frame that positions and locks the two sides of the eyeglass frame 7, a patch assembly that precisely positions the application direction, an automatic hot pressing assembly 4 that performs hot pressing application on the heat sink 9, and a temperature control digital display 1.

[0056] See Figure 6 The frame contouring base 501 has hinge frame positioning seats integrated on both sides of the hinge frame of the eyeglass frame 7 facing the heat-pressed patch, which accurately positions the left and right hinge frames of the heat sink 9 to be attached.

[0057] See Figure 1 The Z-axis lifting slide 2 is connected to a lifting frame 3. An automatic hot pressing component 4 is installed at the lower end of the lifting frame 3. The Z-axis lifting slide 2 controls the automatic hot pressing component 4 to achieve precise lifting and lowering displacement. The lifting frame 3 includes four guide rods and guide sleeves, a lifting plate and a connecting block to ensure the precise movement of the automatic hot pressing component 4 during lifting and lowering.

[0058] As a further solution to this embodiment, see [reference]. Figure 3 andFigure 4 The patch assembly is used to position the heat sink 9 to be applied to the hinge frame in six directions (up, down, left, right, front, and back). It includes patch bases 504 mounted on both sides of the hinge frame positioning seat, elastic pressure frame modules 503 mounted on the outside of the hinge frame positioning seat, and left and right patch positioning modules that accurately position the heat sinks 9 on both sides within the hinge frame.

[0059] The left and right application positioning modules have the same structural principle.

[0060] Further implementation plans are as follows, see [link / reference] Figure 2 , Figure 3 and Figure 4 The patch base 504 is located at the front and rear ends of the hinge frame positioning seat, serving as a positioning reference for the heat sink 9 to be applied, and assisting the application positioning module in quickly positioning the heat sink 9.

[0061] Further implementation plans are as follows, see [link / reference] Figure 4 and Figure 6 The elastic pressure frame module 503 is positioned by a support base and includes a lifting rod and an inner frame pressure block 507. The lifting rod is equipped with a pull button for easy manual upward pulling. The inner frame pressure block 507 is controlled by the lifting rod to achieve lifting and pressing action. The lifting rod and the support base are pushed by a spring to keep the inner frame pressure block 507 applying downward force. The inner frame pressure block 507 applies oblique pressure to the inner wall of the hinge frame in the vertical direction. Under the elastic force, the hinge frame is fully fitted into the contoured groove of the hinge frame positioning seat, realizing the locking of the hinge frame after positioning.

[0062] The particularly important technical solution is, see [reference] Figure 3 , Figure 4 , Figure 5 and Figure 6 Taking the right application positioning module as an example, the right application positioning module includes a right U-shaped block 505 that is attached and positioned to the patch base 504, a right movable reference mechanism that is positioned and attached to the front inner wall 702 of the hinge frame, and a guide pin 8 that is sleeved with the release film to which the heat sink 9 is pasted.

[0063] As a further solution to this embodiment, see [reference]. Figure 7 , Figure 8 and Figure 9 The right U-shaped block 505 has mating surfaces on both sides that are positioned with the patch base 504, which limit the right U-shaped block 505 in four directions (up, down, left, and right). The right U-shaped block 505 has a right inner wall reference block 5059 in the middle that is mated with one side of the rear inner wall 703 of the hinge frame. The right inner wall reference block 5059 and the right movable reference block 5054 cooperate in opposite directions to clamp the front inner wall 702 and the rear inner wall 701 of the right hinge frame, thereby achieving precise positioning of the heat sink 9 and the right hinge frame.

[0064] Similarly, the left U-shaped block 502 is provided with mating surfaces on both sides that are positioned with the patch base 504, maintaining the limitation of the left U-shaped block 502 in four directions (up, down, left, and right). The left U-shaped block 502 is provided with a left inner wall reference block in the middle that is mated with one side of the front inner wall 702 of the hinge frame. The left inner wall reference block and the left movable reference block 5022 cooperate in opposite directions to clamp the inner wall of the left hinge frame, thereby achieving precise positioning of the heat sink 9 and the left hinge frame.

[0065] Further implementation plans are as follows, see [link / reference] Figure 4 , Figure 7 and Figure 10 The right U-shaped block 505 has a right application hole 5051 in the middle for avoiding the automatic hot pressing component 4 to perform hot pressing on the heat sink 9. The right application hole 5051 is also provided with two positioning holes 5056 for passing through guide pins 8. The positioning holes 5056 are also screwed radially with locking screws 5057 for locking the guide pins 8.

[0066] Similarly, the left U-shaped block 502 has a left application hole 5021 in the middle to avoid the automatic hot pressing component 4 from hot pressing the heat sink 9. The left application hole 5021 also has two positioning holes 5056 for passing through guide pins 8 diagonally. The positioning holes 5056 are also screwed radially with locking screws 5057 for locking the guide pins 8.

[0067] As a further solution to this embodiment, see [reference]. Figure 7 A right end face reference block 5058 is provided in the middle of the right U-shaped block 505, facing the upper end face 703 of the right hinge frame. The right end face reference block 5058 fits against the upper end face 703 of the hinge frame. The right end face reference block 5058 is also provided with a clearance groove facing the position occupied by the inner pressure block 507 of the frame, so as to facilitate the positioning and magnetic locking of the right U-shaped block 505.

[0068] As a further solution to this embodiment, see [reference]. Figure 4 and Figure 6 The right movable reference mechanism includes a right reference base 5052, a right push block 5053, and a right movable reference block 5054. The right push block 5053 is connected to the right reference base 5052 through a flexible guide pin shaft hole. The right movable reference block 5054 is connected to the right push block 5053 and passes through the right application hole 5051 to fit against the front inner wall 702 of the right hinge frame. It is also horizontally aligned with the right inner wall reference block 5059. The right movable reference block 5054 is driven to slide linearly by the flexible guide pin.

[0069] Further implementation plans are as follows, see [link / reference] Figure 6 and Figure 7The left U-shaped block 502 and the right U-shaped block 505 are respectively provided with several permanent magnets 5055 on the mating surfaces of the patch base 504, which can firmly lock the left U-shaped block 502 or the right U-shaped block 505 through magnetic adsorption.

[0070] As can be seen from the technical solutions of the above embodiments, the elastic pressure frame module 503 firmly attaches the hinge frame to the hinge frame positioning seat, completing the basic positioning of the heat sink 9. Then, the application positioning module is used to accurately position the heat sink 9 to the inner wall of the hinge frame. The positioning is done in stages, and the accuracy is significantly improved.

[0071] See Figure 1 The automatic hot pressing assembly 4 is driven by the Z-axis lifting slide 2 and includes a lifting frame 3 connected to the slider of the Z-axis lifting slide 2, a left hot pressing module and a right hot pressing module with the same structural principle.

[0072] The left hot pressing module includes a left push electric cylinder, a left positioning frame 401, a left heat insulation block 402 and a left hot pressing block 403 positioned and connected to the front end of the left positioning frame 401. The left hot pressing block 403 is equipped with an electric heating rod 406 and a temperature sensor 405. The lower part is equipped with a left hot pressing head 4031. The pressing surface of the left hot pressing head 4031 is designed according to the shape of the concave inner wall of the hinge frame. The pressing surface slides linearly opposite the left application hole 5021 and presses the positioned heat sink 9, heating and softening the heat sink 9 and applying pressure to apply it to the inner wall of the hinge frame.

[0073] And so on, see below. Figure 2 The right hot-pressing module includes a right push-up electric cylinder 404, a right positioning frame, a right heat insulation block and a right hot-pressing block 407 positioned and connected to the front end of the right positioning frame. The right hot-pressing block 407 contains an electric heating rod 406 and a temperature sensor 405, and a right hot-pressing head is located at its lower part. The pressing surface of the right hot-pressing head is designed according to the shape of the concave inner wall of the hinge frame. The pressing surface slides linearly opposite the right application hole 5051 and presses down on the positioned heat sink 9, heating and softening it before applying pressure to the inner wall of the hinge frame. The heating and softening method removes internal stress from the heat sink 9, facilitating a full fit between the flat heat sink 9 and the concave inner wall of the hinge frame, eliminating air gaps and air bubbles on the bonding surface, and ensuring a secure bond.

[0074] In summary, this smart glasses' internal hot-press bonding device for the left and right hinge frames utilizes a bonding assembly to precisely position the heat sink to be bonded onto the inner wall of the hinge frame. An automatic hot-pressing assembly then assists in heating, softening, and pressurizing the heat sink onto the inner wall of the hinge frame, achieving precise, efficient, and convenient heat sink bonding. (See also...) Figure 9 Considering that the internal screws occupying the bonding space in the hinge frame must also be avoided, which makes the heat sink bonding accuracy requirement higher, using this equipment is more conducive to efficient mass production of heat sinks.

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.
