Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a positioning and pressure-holding fixture for the left and right microphone components of smart glasses. Background Technology

[0002] Smart wearable devices are gaining popularity among young people in today's society. Smartwatches, smart glasses, and smart Bluetooth headsets have enriched communication and entertainment options. Among them, AI smart glasses, as wearable devices that integrate multiple functions such as listening, seeing, speaking, and translation, are rapidly capturing the global market. The variety and production scale of AI smart glasses are also constantly increasing, and breakthroughs are being made in the functionality of smart glasses.

[0003] AI smart glasses are equipped with multiple microphones (MICs) and speaker units to accommodate different angles for audio recording and playback. Therefore, MICs are typically located at the left and right hinges between the temples and the frame. When assembling the MICs, recording holes need to be created in the frame to form a sound reception channel for receiving sound signals. However, waterproofing, dustproofing, and moisture protection must also be considered. Therefore, a ring of sealant needs to be applied around the MICs and frame assembly, followed by pressure curing. However, current smart glasses production equipment almost entirely lacks the tooling for applying a ring of sealant and then applying pressure to position and bond the MICs to the frame. To meet mass production requirements, a pressure-pressurizing tooling solution to this problem is urgently needed. Utility Model Content

[0004] The purpose of this invention is to address the technical problem of ensuring good sealing performance between the left and right microphone elements and the frame of existing smart glasses after applying a ring of sealant to the bonding positions. This tool is needed to pressurize the microphone elements, which are positioned and bonded by the sealant, to the frame until they are cured and connected.

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

[0006] A positioning and pressure-holding fixture for the left and right microphone components of smart glasses is proposed, including...

[0007] The base supports the main structure of the positioning tooling.

[0008] A contouring platform for positioning and supporting eyeglass frames, wherein the upper surface of the contouring platform is provided with a concave contouring groove for the eyeglass frames.

[0009] And a positioning and pressure-holding assembly for positioning and pressing the left and right microphone elements and the eyeglass frame, the positioning and pressure-holding assembly including an eyeglass frame positioning module and a microphone pressure-holding module.

[0010] The contouring stage is equipped with contouring blocks that conform to the hinge shells connecting the two sides of the eyeglass frame to the temples. The contouring blocks have embedded contouring curved surfaces at the contact points with the hinge shells, effectively positioning and limiting the hinge shells on both sides of the eyeglass frame to which the MIC component is to be assembled.

[0011] The eyeglass frame positioning module is located on both sides of the eyeglass frame, and a positioning and clamping mechanism is set directly opposite the recording hole of the eyeglass frame.

[0012] The MIC pressure holding module applies pressure to the MIC element inside the hinge housing of the eyeglass frame, including a pressure holding mechanism and an elastic element that applies the pressure holding force.

[0013] Furthermore, the positioning and clamping mechanism includes a push clamp and a positioning plate. The positioning plate is attached to the front end face of the push rod of the push clamp. The push rod pushes against the recording hole of the eyeglass frame. The positioning plate is in close contact with the outer shell around the recording hole, which plays a role in positioning, supporting and preventing wear.

[0014] Furthermore, the pressure holding mechanism includes a pressure holding arm, a pressure holding seat, and a slider-rail assembly. The pressure holding arm is connected to the pressure holding seat, and the pressure holding seat is connected to the slider. The pressure holding arm is provided with a pressure holding head facing the MIC element. Under the linear sliding action of the slider-rail, the pressure holding head is driven to push and hold pressure on the MIC element.

[0015] Furthermore, the pressure holding arm and the pressure holding base are detachably connected. The pressure holding arm is integrally connected with a magnetic block. The magnetic block has hooks on both sides and a permanent magnet on its bottom surface. The bottom surface of the magnetic block has a positioning hole. The magnetic block and the positioning pin hole on the pressure holding base are fitted together to ensure accurate positioning of the magnetic block and the pressure holding base. After the hooks on both sides are clamped to the pressure holding base and the opposite poles of the permanent magnet and the permanent magnet on the pressure holding base are attracted, the block is fully locked.

[0016] Furthermore, the two side hooks are movably connected to the magnetic block via a hinge shaft, and the hooks are pushed against the upper part of the magnetic block by a return spring to ensure that the hooks are locked to the pressure-holding seat.

[0017] Furthermore, a limit stop is provided at the lower end of the pressure holding seat. The limit stop cooperates with the limit push seat provided on the base, and a push spring is provided between the limit stop and the limit push seat. The push spring pushes the pressure holding seat and drives the pressure holding arm to push the MIC element.

[0018] Furthermore, the positioning and clamping mechanism is replaced by a first clamping arm, and the pressure-holding mechanism is replaced by a second clamping arm. The first and second clamping arms are movably connected by a central shaft to form a clamp shape. A pressure-holding spring is provided on the upper opposing inner surfaces between the first and second clamping arms, while a positioning clamp and a pressure-holding clamp are respectively provided on the lower opposing inner surfaces between the first and second clamping arms. The positioning clamp is in close contact with the outer shell around the recording hole, and the pressure-holding clamp is directly pushing and holding the MIC element.

[0019] Furthermore, a T-shaped shaft head is provided on the outside of the central shaft, and it is in clearance fit with the T-shaped groove of the positioning block provided on the contour table, which is used to limit the positional accuracy of the central shaft and support the structure.

[0020] Furthermore, on the profiling platform, several magnetic pressing blocks are arranged around the perimeter of the positioned eyeglass frame. The magnetic pressing blocks are attracted to the permanent magnets on the profiling platform and press the upper and lower frames of the eyeglass frame tightly.

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

[0022] 1. The smart glasses left and right MIC positioning and pressure holding fixture uses a contour stage to fully position the smart glasses frame to be assembled and pressure-held MIC components, ensuring the basic positional accuracy of the preceding positioning and pressure holding processes;

[0023] 2. By aligning and clamping the outer frame shell and the inner MIC element with pressure, the adhesive or tape and other sealants are fully filled in the assembly gap between the two, ensuring the airtightness of the smart glasses and improving the product performance of waterproof, moisture-proof and dustproof.

[0024] 3. Using elastic elements as a technical solution to achieve top-pushing clamping, materials with different elastic strengths are selected according to the actual pressure to obtain different pressure holding pressures; the detachable pressure holding mechanism provides technical conditions for modular and standardized pressure holding.

[0039] Example 1:

[0040] Please see Figure 1 This embodiment proposes a positioning and pressure-holding fixture for left and right microphones of smart glasses, including a base 1 supporting the main structure of the positioning fixture, a contouring stage 2 for positioning and supporting the eyeglass frame 7, and a positioning and pressure-holding assembly for positioning and pressing the left and right microphone elements 9 and the eyeglass frame 7. The upper end surface of the contouring stage 2 is provided with a concave contouring groove of the eyeglass frame 7, and the positioning and pressure-holding assembly includes an eyeglass frame positioning module and a microphone pressure-holding module.

[0041] See Figure 1 and Figure 2 The contouring stage 2 is provided with contouring blocks that fit the hinge shells 10 on both sides of the eyeglass frame 7 and are connected to the temples. The contouring blocks are provided with embedded contouring curved surfaces at the contact positions with the hinge shells 10, which fully position and limit the hinge shells 10 on both sides of the eyeglass frame 7 to be assembled with the MIC element 9.

[0042] See Figure 1 , Figure 4 and Figure 6The frame positioning module is located on both sides of the eyeglass frame 7, and a positioning and clamping mechanism is set directly opposite the recording hole 1001 of the eyeglass frame 7. It includes a left push clamp 3 and a right push clamp 4, as well as a positioning piece attached to the front end face of the push rod of the left push clamp 3 and the right push clamp 4. The positioning piece is made of hard, anti-static material to ensure positioning and support of the recording hole 1001 while preventing static electricity from damaging the internal components of the smart glasses. It is attached to the front end face of the push rod of the push clamp. The push rod pushes against the recording hole 1001 of the eyeglass frame 7. The positioning piece is in close contact with the outer shell around the recording hole 1001, which plays a role in positioning, supporting, and preventing wear.

[0043] See Figure 2 , Figure 3 and Figure 4 The MIC pressure holding module applies pressure to the MIC element 9 inside the left and right hinge housings 10 of the eyeglass frame 7, including a left pressure holding mechanism, a right pressure holding mechanism, and an elastic element that applies pressure.

[0044] A further implementation scheme, taking the left side as an example, includes a left pressure holding mechanism comprising a left pressure holding arm 503, a left pressure holding seat 502, and a slider rail assembly 8. The left pressure holding arm 503 is connected to the left pressure holding seat 502, and the left pressure holding seat 502 is connected to the slider. The left pressure holding arm 503 is provided with a left pressure holding head 5031 facing the MIC element 9. Under the linear sliding action of the slider rail, the left pressure holding head 5031 is driven to push and hold pressure on the MIC element 9.

[0045] Similarly, the right-side pressure holding mechanism includes a right-side pressure holding arm, a right-side pressure holding seat, and a slider-rail assembly 8. The right-side pressure holding arm is connected to the right-side pressure holding seat, and the right-side pressure holding seat is connected to the slider. A right-side pressure holding head 5031 is positioned directly opposite the MIC element 9 on the right-side pressure holding arm. Under the linear sliding action of the slider-rail assembly, the right-side pressure holding head 5031 is driven to push and hold pressure against the MIC element 9.

[0046] As a further implementation of Embodiment 1, the left pressure-holding arm 503 is detachably connected to the left pressure-holding seat 502. The left pressure-holding arm 503 is integrally connected to a left magnetic block 504. Left magnetic blocks 504 have left clamping hooks 505 on both sides and a left permanent magnet 508 on its bottom surface. A positioning hole is provided on the bottom surface of the left magnetic block 504. The left magnetic block 504 and the positioning pin 6022 on the left pressure-holding seat 502 are fitted together through the shaft hole to ensure accurate positioning of the left magnetic block 504 and the left pressure-holding seat 502. After the left clamping hooks 505 and the left pressure-holding seat 502 are engaged, and the opposite poles of the left permanent magnet 508 and the permanent magnet 508 on the pressure-holding seat attract each other, the system is fully locked in place. The same applies to the right side.

[0047] A further implementation scheme is that the two side hooks are movably connected to the magnetic block through a hinge shaft, and the return spring 507 pushes the hooks and the upper part of the magnetic block to ensure the locking posture of the hooks on the pressure holding seat.

[0048] A further implementation scheme is that a limit stop is provided at the lower end of the pressure holding seat. The limit stop cooperates with the limit push seat provided on the base 1, and a push spring 506 is provided between the limit stop and the limit push seat. The push spring 506 pushes the pressure holding seat and drives the pressure holding arm to push against the MIC element 9.

[0049] Example 2:

[0050] See Figure 7 and Figure 8 This embodiment proposes a positioning and pressure-holding fixture for the left and right microphones of smart glasses, including a base 1 supporting the main structure of the positioning fixture, a contour stage 2 for positioning and supporting the eyeglass frame 7, and a positioning and pressure-holding assembly for positioning and pressing the left and right microphone elements 9 and the eyeglass frame 7. The difference from embodiment 1 is that the positioning and pressing mechanism is replaced by a first clamping arm 11, and the pressure-holding mechanism is replaced by a second clamping arm 12. The first clamping arm 11 and the second clamping arm 12 are movably connected by a central shaft to form a clamp shape. A pressure-holding spring is provided on the upper opposing inner surfaces between the first clamping arm 11 and the second clamping arm 12, and a positioning clamp 1101 and a pressure-holding clamp 1201 are respectively provided on the lower opposing inner surfaces between the first clamping arm 11 and the second clamping arm 12. The positioning clamp 1101 is close to the outer shell around the recording hole 1001, and the pressure-holding clamp 1201 pushes and holds pressure on the microphone element 9.

[0051] As a further implementation of this embodiment 2, see [reference]. Figure 9 The central shaft has a T-shaped head on its exterior, which engages with a T-shaped groove 1301 on the positioning block 13 on the contour stage 2 to limit the positional accuracy of the central shaft and support the structure. The pressure-holding structure of this embodiment is simpler and more practical, and the detachable "clamp" makes it easier to disassemble and replace the eyeglass frame 7, thus improving the pressure-holding efficiency.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. For those skilled in the art, various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of this utility model.
