Description

Technical Field

[0001] This invention relates to the field of smart glasses manufacturing equipment technology, specifically to a hot-press bonding equipment for the metal dustproof mesh inside the temple of glasses. Background Technology

[0002] As a next-generation wearable device integrating augmented reality (AR), voice interaction, and spatial computing, smart glasses face the core challenge of achieving highly reliable acoustic output and environmental adaptability within limited spaces. The temple speakers, as a key component for audio interaction, have their dustproof mesh technology directly impacting sound quality stability, device lifespan, and user experience.

[0003] The speakers in the temples of smart glasses need to operate in open environments. Their acoustic structures (such as diaphragms and voice coils) are highly susceptible to corrosion from contaminants such as dust, sweat, and moisture, leading to sound quality degradation (such as high-frequency distortion and low-frequency attenuation), shortened speaker lifespan, and even equipment failure. The dustproof mesh, as the first barrier between the speaker and the outside environment, must simultaneously meet the following requirements:

[0004] Breathability: Allows sound waves to pass freely, avoiding sound quality loss due to increased impedance;

[0005] Filtration: Blocks PM2.5 and larger particulate matter (such as dust and pollen) and liquid pollutants (such as sweat and rainwater);

[0006] Durability: Withstands repeated bending, friction and extreme temperatures (-20℃ to 60℃) and maintains long-term stability;

[0007] Concealment: The thickness needs to be controlled within 0.1mm to avoid affecting the slim design of the temples (the thickness of temples in mainstream products is about 4-8mm).

[0008] Currently, in the global smart glasses market, the dustproof mesh of the temple speaker is mainly installed to the temple using either a snap-fit ​​connection or adhesive bonding. Snap-fit ​​connections increase the weight of the internal clamping structure of the temple, and speaker vibrations can loosen the connection, eventually leading to rattling noise from the dustproof mesh. Adhesive bonding, on the other hand, uses double-sided tape or hot melt adhesive to directly attach the dustproof mesh to the sound hole on the inner wall of the temple. This method offers advantages such as lightweight, thinness, low cost, corrosion resistance, and ease of processing. Therefore, adhesive bonding, especially hot melt adhesive bonding, is currently the preferred installation solution.

[0009] Currently, there are very few devices that can automatically assemble the adhesive dustproof mesh and temples of smart glasses speakers. It is necessary to design an automated device to achieve the goal of accurately attaching the speaker dustproof mesh and the temples of smart glasses. Summary of the Invention

[0010] The problem this invention aims to solve is that there are very few existing devices for precisely attaching the speaker dustproof mesh and the sound hole in the temple of smart glasses using hot melt adhesive. This invention proposes a hot-press attachment device for the metal dustproof mesh inside the temple. A ceramic heating element is attached to the inner surface of the metal dustproof mesh, and hot melt adhesive is melted by heating. Simultaneously, the mesh is precisely attached to the sound hole in the temple. After the metal dustproof mesh is pressurized and the hot melt adhesive cools and solidifies, precise attachment is achieved, meeting the mass production needs of assembling metal dustproof mesh in smart glasses.

[0011] The technical solution adopted to solve the above problems is:

[0012] A hot-pressing device for attaching metal dustproof mesh to the inner temple of a pair of eyeglasses is proposed, including...

[0013] A feed slide is mounted on the worktable, and a magnetic suction fixture is provided on the slider of the feed slide.

[0014] A positioning carrier for smart glasses with a speaker-mounted metal dustproof mesh to be attached.

[0015] A lifting and sliding assembly is positioned and connected by a gantry frame. The slider of the lifting and sliding assembly is connected to a lifting frame. The lifting frame is connected to a positioning plate. Guide rod and guide sleeve assemblies are symmetrically arranged at the four corners of the positioning plate.

[0016] The hot-press bonding assembly is connected by multiple sets of guide rod and guide sleeve assemblies. The hot-press bonding assembly includes two sets of force equalizers for balancing the clamping force, electric grippers, and a hot-press bonding module for applying a metal dustproof mesh to the inner and outer walls of the sound hole facing the temple of the mirror through pressure heat melting.

[0017] Furthermore, the positioning carrier includes a base with a permanent magnet and a positioning bushing. After the positioning bushing of the base is engaged with the positioning pin of the magnetic suction fixture, it is attracted and locked by the permanent magnet. The positioning carrier also includes a temple contouring platform, several elastic pressure blocks, and a hinged pressure rod.

[0018] Furthermore, the upper surface of the temple contouring platform is provided with a positioning contouring groove that has the same shape as the outer surface contour of the temple to be positioned. The temple is placed in the positioning contouring groove, and the temple shell is pressed by several elastic pressure blocks evenly distributed around the temple contouring platform to complete the pressing. Then, the temple shell is pressed and locked by the hinged pressure rod.

[0019] Furthermore, the force equalizer is attached to the bottom of the positioning plate and includes a slide rail arranged along the clamping direction of the electric gripper, an equalization platform that fits into the slide rail, and a reset push block driven by a top-push cylinder. The electric gripper is connected below the equalization platform, and the two grippers that slide and clamp relative to each other are connected to the hot-press bonding module.

[0020] Furthermore, the reset push block is provided with a conical push head facing the side of the equalization platform. The conical push head fits into the conical notch provided on the side of the equalization platform to calibrate and reset the misalignment and offset of the equalization platform along the slide rail direction.

[0021] Furthermore, the hot-press bonding module includes a connecting block, a stop block that adheres to the outer wall of the sound hole of the temple, and a hot-pressing block that adheres to the inner wall of the sound hole of the temple and presses the metal dustproof mesh. The hot-pressing block is provided with a heat-conducting groove, and a ceramic heating element is provided inside the heat-conducting groove to conduct controllable heat to the hot-pressing block. The stop block and the hot-pressing block are respectively located at the lower part of the two connecting blocks, and the two connecting blocks are respectively connected to two clamps.

[0022] Furthermore, the gantry frame is also connected to a pressing and fitting assembly arranged directly opposite the inner cavity of the temple. The pressing and fitting assembly includes an electric push rod, a push base, a guide post and guide sleeve, a pressing plate, and a pressing block. The pressing plate is connected to the push base via the guide post and guide sleeve, and slides linearly with the push base. The pressing block is connected below the pressing plate. The electric push rod presses down and pushes the pressing block to fully press the release paper with the metal dustproof mesh, so as to ensure that the metal dustproof mesh is accurately positioned with the inner walls of the sound holes on the left and right sides of the temple, without misalignment or deviation.

[0023] Furthermore, a pressure sensor is also provided between the push base and the pressing plate to ensure that when the electric push rod presses down on the pressing block, the pressing pressure of the pressing block on the release paper and the inner surface of the temple is monitored and controlled.

[0024] Furthermore, a micro-pressure sensor is also installed between the connecting block that cooperates with the hot pressing block and the electric gripper to monitor the pressing pressure of the hot pressing block on the metal dustproof mesh, thereby ensuring that the hot melt adhesive, after being softened by heat, is fully bonded in the gap between the metal dustproof mesh and the inner wall of the sound hole of the temple, rather than being squeezed out of the gap and affecting the bonding firmness.

[0025] Furthermore, a heat insulation plate is provided on the outer side of the ceramic heating element. The heat insulation plate is attached to the surface of the hot pressing block to ensure that the heat generated is not transferred to the surrounding parts, to ensure that the hot pressing block absorbs more heat, to isolate the heat interference source, and to hold the outer wall of the temple at a low temperature without scalding the outer wall of the temple.

[0026] Furthermore, the contact surface between the adhesive block and the release paper is provided with a soft pad to reduce the impact on the inner surface of the temple in a soft contact manner, and to distribute the pressing pressure to each point, thereby improving the adhesion between the release paper and the inner surface.

[0027] Furthermore, the contact surface of the stop block that fits against the outer wall of the sound hole of the temple is provided with a hard anti-wear layer to protect the appearance quality of the outer wall of the temple. The contact surface of the hot pressing block that fits against the inner wall of the sound hole of the temple is provided with a heat-conducting and anti-slip layer to tightly fit the metal dustproof mesh, transfer heat, and prevent it from sliding or misaligning.

[0028] The beneficial effects of the technical solution of this invention are:

[0029] 1. This hot-pressing equipment for attaching metal dustproof mesh inside the temple uses electric grippers to precisely apply force to the temple, which is positioned and locked in the positioning carrier, and clamps and attaches it. It also uses ceramic heating elements to conduct heat to the metal dustproof mesh and controls the appropriate heating temperature so that the hot melt adhesive between the metal dustproof mesh and the inner wall of the temple reaches the melting temperature, which facilitates the adhesion between the two. After the hot melt adhesive cools and solidifies, the precise attachment operation is achieved, which meets the mass production needs of assembling metal dustproof mesh for smart glasses.

[0030] 2. By using a micro-pressure sensor to control the pressing pressure of the hot press block on the metal dustproof mesh, the hot melt adhesive, after being softened by heat, is fully bonded to the gap between the metal dustproof mesh and the inner wall of the sound hole of the temple, rather than being squeezed out of the gap and affecting the bonding strength.

[0031] 3. The force equalizer is used to remove the force deviation caused by the electric grippers clamping each other. The equalizer and the slide rail are flexibly sliding together to remove the asymmetrical squeezing force on both sides, so as to achieve the force balance on both sides of the stop block and the hot pressing block. This prevents the electric grippers from driving the stop block or the hot pressing block to damage the temple and the metal dustproof net, thus protecting the appearance quality of the product.

[0032] 4. Securely attach the release paper with the metal dustproof mesh to the inner surface of the temple by pressing the assembly. This provides a positioning basis for the stop and hot press block to accurately attach the metal dustproof mesh to the inner wall of the sound hole. After attaching the metal dustproof mesh to the temple, simply peel off the release paper.

[0033] 5. The positioning carrier, the bonding block of the bonding and pressing component, and the hot pressing module of the hot pressing component in this equipment can all be adapted to the appropriate specifications of modules according to different smart glasses models. The remaining structural components can be standardized to meet the bonding process requirements of most smart glasses for the metal dustproof mesh inside the temples. The standardization is high, reducing the cost of repeated equipment development. Attached Figure Description

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.

[0051] Please see Figure 1 This embodiment proposes a hot-pressing device for attaching metal dustproof mesh inside the temple of a mirror, including a feed slide 2 set on a worktable 1. A magnetic suction fixture 3 is set on the slider of the feed slide 2. The upper surface of the magnetic suction fixture 3 is provided with a positioning pin and a permanent magnet, and a limiting strip is set on the front and rear sides.

[0052] See Figure 8 It also includes a positioning carrier 4 for positioning and clamping smart glasses to be fitted with a metal dustproof mesh for speakers. The positioning carrier 4 includes a base with a permanent magnet and a positioning bushing. After the positioning bushing of the base is fitted with the positioning pin of the magnetic fixture 3, the permanent magnet attracts each other to complete the locking. The positioning carrier 4 also includes a temple contouring platform 401, four sets of elastic pressure blocks 402 and a hinged pressure rod 403.

[0053] Further implementation plans are as follows, see [link / reference] Figure 8The upper surface of the temple contouring platform 401 is provided with a positioning contouring groove that has the same shape as the outer surface contour of the temple 10 to be positioned. The temple 10 is placed in the positioning contouring groove, and the temple 10 housing is pressed by four sets of elastic pressure blocks 402 evenly distributed around the temple contouring platform 401 to complete the pressing. Then, the hinged pressure rod 403 presses and locks the temple 10 housing, completing the positioning and locking process before the hot-pressing of the horn metal dustproof mesh onto the temple 10.

[0054] See Figure 1 and Figure 2 The equipment also includes a lifting and sliding assembly 7 positioned and connected by a gantry frame 8. The slider of the lifting and sliding assembly 7 is connected to a lifting frame 6. The lifting frame 6 is connected to a positioning plate. Guide rod and guide sleeve assemblies 601 are symmetrically arranged at the four corners of the positioning plate.

[0055] See Figure 4 , Figure 5 and Figure 6 The device also includes a hot-press bonding assembly connected by a guide rod and guide sleeve assembly 601. The hot-press bonding assembly includes two sets of force equalizers for balancing the clamping force, two electric grippers 501 respectively set facing the upper and lower frames of the temple 10, and two sets of hot-press bonding modules 5 for hot-melting bonding of metal dustproof mesh against the inner and outer walls of the sound hole 101 of the temple 10.

[0056] As a further solution to this embodiment, see [reference]. Figure 6 The force equalizer is attached to the bottom of the positioning plate and includes a slide rail 510 arranged along the clamping direction of the electric gripper 501, an equalization platform 509 that is sleeved with the slide rail 510, and a reset push block 507 driven by the push cylinder 508.

[0057] Specifically, see Figure 6 The reset push block 507 is controlled by the slider rail assembly 506 to slide linearly towards the equalizer 509, and a conical push head 5071 is provided on the side of the equalizer 509. The conical push head 5071 fits into the conical notch 5091 provided on the side of the equalizer 509, and corrects and resets the misalignment and offset of the equalizer 509 along the rail 510 caused by the asymmetrical force generated by the electric gripper 501 on the upper or lower frame of the temple 10.

[0058] As a further solution to this embodiment, see [reference]. Figure 8 The electric gripper 501 is connected below the equalization platform 509. The first gripper 512 and the second gripper 511 of the electric gripper 501 are connected to the hot pressing bonding module 5 by sliding and clamping in opposite directions.

[0059] Specifically, see Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 The hot-press bonding module 5 includes a connecting block, a stop block that adheres to the outer wall of the temple sound hole 101, and a hot-pressing block that adheres to the inner wall of the temple sound hole 101 and presses the metal dustproof mesh. That is, the first set of hot-press bonding modules includes a connecting block, a first stop block 502, and a first hot-pressing block 503 that adheres to the inner wall of the temple sound hole 101 and presses the metal dustproof mesh. The second set of hot-press bonding modules includes a connecting block, a second stop block 504, and a second hot-pressing block 505 that adheres to the inner wall of the temple sound hole 101 and presses the metal dustproof mesh.

[0060] Specifically, the hot pressing block is provided with a heat conduction groove 5032, and a ceramic heating element 514 is provided inside the heat conduction groove 5032 to conduct controllable heat to the hot pressing block. The baffle and the hot pressing block are respectively located at the lower part of the two connecting blocks, and the two connecting blocks are respectively connected to the two clamps.

[0061] See Figure 8 and Figure 12 A micro-pressure sensor 513 is also provided between the connecting block that cooperates with the hot pressing block and the electric gripper 501 to monitor the pressing pressure of the hot pressing block on the metal dustproof mesh, thereby ensuring that the hot melt adhesive, after being softened by the hot melt, is fully bonded in the gap between the metal dustproof mesh and the inner wall of the sound hole 101 of the temple, rather than being squeezed out of the gap and affecting the bonding firmness.

[0062] When the electric gripper 501 drives the stop block and the hot pressing block to clamp against the outer and inner walls of the temple 10, the flexibly sliding cooperation of the equalization platform 509 and the slide rail 510 removes the asymmetrical squeezing force on both sides, achieving a force balance on both sides of the stop block and the hot pressing block, so as to prevent the electric gripper 501 from damaging the temple 10 and the metal dustproof net.

[0063] Specifically, see Figure 10 and Figure 11 The outer side of the ceramic heating element 514 is provided with a heat insulation plate 515, which is attached to the surface of the hot pressing block to ensure that the heat generated is not transferred to the surrounding parts, to ensure that the hot pressing block absorbs more heat, to isolate the heat interference source, and to hold the outer wall of the temple 10 at low temperature without burning the outer wall of the temple 10.

[0064] Further implementation plans are as follows, see [link / reference] Figure 7 and Figure 10 The contact surface of the stop block that fits into the outer wall of the sound hole 101 of the temple is provided with a hard anti-wear layer 5021 to protect the appearance quality of the outer wall of the temple 10. The contact surface of the hot pressing block that fits into the inner wall of the sound hole 101 of the temple is provided with a heat-conducting and anti-slip layer 5031 to tightly fit the metal dustproof mesh to transfer heat and prevent it from sliding and misaligning.

[0065] As a further solution to this embodiment, see [reference]. Figure 2 and Figure 3The gantry frame 8 is also connected to a pressing assembly 9 arranged directly opposite the inner cavity of the temple 10. The pressing assembly 9 includes an electric push rod, a push seat, a guide post and guide sleeve 902, a pressing plate 903, and a pressing block 904. The pressing plate 903 is connected to the push seat via the guide post and guide sleeve 902 and slides linearly with the push seat. The pressing block 904 is connected below the pressing plate 903. The electric push rod presses down and pushes the pressing block 904 to fully press the release paper with the metal dustproof mesh to ensure that the metal dustproof mesh is accurately positioned with the inner wall of the sound holes 101 on the left and right sides of the temple 10, without misalignment or deviation.

[0066] Further implementation plans are as follows, see [link / reference] Figure 3 A pressure sensor 901 is also provided between the push seat and the pressing plate 903 to ensure that when the electric push rod presses down on the pressing block 904, it monitors and controls the pressing pressure of the pressing block 904 on the release paper and the inner surface of the temple 10, so as to ensure that the release paper and the inner surface of the temple 10 are firmly adhered, and the physical structure of the temple 10 is not damaged.

[0067] Further implementation plans are as follows, see [link / reference] Figure 3 The surface of the adhesive block 904 that contacts the release paper is provided with a soft pad 9041 to reduce the impact on the inner surface of the temple 10 in a soft contact manner and to distribute the pressing pressure to each point, thereby improving the adhesion between the release paper and the inner surface.

[0068] 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.
