Description

Technical Field

[0001] This invention relates to the field of smart glasses manufacturing equipment technology, specifically to a positioning and assembly fixture for camera modules inside eyeglass frames. Background Technology

[0002] As a key wearable device, smart glasses typically feature camera modules on both sides of the frame for functions such as taking photos, making video calls, and augmented reality (AR) overlay. Since the left and right camera modules need to work together to achieve functions like stereoscopic vision and spatial positioning, the relative positional accuracy between the two modules directly affects image quality and user experience.

[0003] In current smart glasses manufacturing, camera modules are mostly fixed to the frame using adhesive or clips. However, the frame itself has injection molding tolerances, and coupled with the uncertainty of manual assembly, it is difficult to guarantee the parallelism and spacing accuracy of the optical axes of the left and right modules. Excessive alignment deviation can lead to problems such as binocular vision mismatch and AR overlay misalignment, sometimes requiring rework or even scrapping. While simple positioning fixtures exist for camera module installation, they lack precise pre-positioning of the slots for the camera modules and fail to fully align them during assembly, resulting in assembly angle deviations. These deviations can range from minor issues like poor post-adhesive positioning after curing to serious damage such as collisions between the camera module and the frame. Therefore, a precision fixture capable of achieving high-precision alignment and installation of the left and right camera modules is urgently needed to meet the quality requirements of mass-produced smart glasses. Summary of the Invention

[0004] The purpose of this invention is to address the practical problems of ensuring the parallelism and spacing accuracy of the optical axes of the left and right camera modules due to the injection molding tolerances inherent in eyeglass frames and the uncertainties of manual assembly. Furthermore, existing simple positioning fixtures are unable to accurately pre-position the slots for the camera modules to be installed, and it is difficult to fully and accurately align the slots during camera module assembly, resulting in assembly angle deviations. Therefore, it is necessary to design a precision fixture that can achieve high-precision alignment and installation of the left and right camera modules to meet the quality requirements of mass production of smart glasses.

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

[0006] A positioning and assembly fixture for an in-eyeglass frame camera module is proposed, including...

[0007] An eyeglass frame positioning carrier includes a base, a contouring platform, elastic blocks, and a telescopic pin that fits into the camera slot of the eyeglass frame where a camera module will be installed. The contouring platform has a contouring positioning groove designed to conform to the outer contour of the eyeglass frame to which the camera module will be assembled, and several elastic blocks are arranged around the contouring positioning groove. The elastic blocks press and lock the upper and lower frames of the eyeglass frame, which are positioned and stationary within the platform.

[0008] The assembly frame, positioned and supported above the contour table, includes a support frame, a movable locking rod, and an assembly plate.

[0009] The loading platform is used to position the camera module to be assembled and align the assembly path of the camera module along the axis of the camera slot hole in the eyeglass frame. The loading platform includes an adjustment plate, a positioning pin for alignment, a positioning locking rod, an elastic pressure holding clamp, and an assembly guide seat, as well as a clamping and loading assembly for accurately positioning and placing the camera module.

[0010] The probe assembly and pressure holding assembly is used to complete the precise assembly of the camera module and the eye frame. The probe assembly and pressure holding assembly includes a slider, a pressure holding block, a probe rod for precise guidance of assembly, and a pressure holding module to maintain the stability of the posture before the glue cures after assembly.

[0011] Furthermore, the contouring stage is provided with a telescopic hole that mates with the telescopic pin hole. The lower end of the telescopic pin is connected to a passive block. The passive block is placed in a rectangular hole opened in the contouring stage and moves up and down, causing the telescopic pin to protrude or retract in the camera slot hole.

[0012] Furthermore, the passive block is pushed by a telescopic spring, causing the telescopic pin to protrude into the camera slot as the initial state.

[0013] Furthermore, the passive block is secured or released by the locking module, and during the assembly of the camera module, the telescopic pin is always kept in the retracted state. The locking module includes a bolt, a lock seat, and a locking spring. A manual wrench is provided on the outside of the bolt, and a locking tongue is provided opposite the passive block to prevent it from sliding upwards.

[0014] Furthermore, a support limiting pin is provided on the lower end face of the support frame. The support limiting pin is fitted with a support bushing provided on the base to complete the positioning of the support frame. The movable locking rod is movably hinged to the outside of the support frame through a hinge block. A locking hook is provided at the lower end. The locking hook engages with a support locking block fixed to the outside of the base to lock the assembly frame. The assembly plate is mounted on the support frame. Positioning bushings and positioning locking blocks are provided on both sides of the assembly plate.

[0015] Furthermore, the upper surface of the attitude adjustment plate is set at a certain angle, and the normal of the upper surface is parallel to the assembly path of the camera module to be assembled, serving as the positioning reference surface for the assembly action. The positioning pins are set on both sides of the lower end face of the attitude adjustment plate and are fitted through the positioning bushing shaft hole. The positioning locking rods are set on both sides of the attitude adjustment plate and are engaged with the positioning locking blocks to achieve the fitting, positioning, and locking of the attitude adjustment plate and the assembly plate.

[0016] Furthermore, the elastic pressure-holding clamp is equipped with a pressure-holding seat, a pressure-holding spring, and a pressure-holding locking block for continuous pressing to complete the assembly of the camera module, as well as a pusher seat for supporting the probe assembly pressure-holding component. The pressure-holding locking block is movably hinged to the pressure-holding seat and is pushed by the pressure-holding spring. The pusher seat is mounted on both sides of the probe rod and is equipped with a pusher spring to support the pressure-holding block, so as to prevent the probe assembly pressure-holding component from falling quickly and colliding with the product.

[0017] Furthermore, the assembly guide seat is mounted on the attitude adjustment plate, and a slide rail is provided on the inner side that slides parallel to the assembly path of the camera module. The slide rail cooperates with the probe assembly pressure holding component to realize the linear sliding motion control of the probe assembly pressure holding component.

[0018] Furthermore, the clamping and feeding assembly includes a front positioning block, a rear positioning block, a front clamping block, a rear clamping block, an elastic slide rod, a sliding sleeve, and a flip handle arranged in alignment. The front clamping block achieves distance adjustment by cooperating with the sliding sleeve through the elastic slide rod arranged perpendicular to the inner side of the front positioning block. The rear clamping block achieves distance adjustment by cooperating with the sliding sleeve through the elastic slide rod arranged perpendicular to the inner side of the rear positioning block. Both the front clamping block and the rear clamping block utilize a pull rod and a flip handle to control their telescopic displacement.

[0019] Furthermore, the inner surfaces of the front clamping block and the rear clamping block are respectively provided with a front reference groove and a rear reference groove facing the camera module to be assembled. The front reference groove and the rear reference groove will accurately position the camera module placed on them. After being adsorbed and grasped by the probed assembly pressure holding component, it will be precisely filled and assembled with the camera slot hole of the eyeglass frame.

[0020] Furthermore, the slider cooperates with the slide rail, the slider is connected to the pressure holding block, and a probe rod is connected below the pressure holding block. An air extraction hole is provided in the center of the probe rod, and an air extraction interface is connected to the upper end of the air extraction hole. An external air extraction device is used to extract air, and a soft adsorption pad is connected to the lower end of the air extraction hole. After the soft adsorption pad is attached to the surface of the camera module's housing, the air extraction adsorption grips the camera module.

[0021] Furthermore, the pressure-holding module is located on the upper end of the pressure-holding block and includes a limiting block, a limiting screw, a limiting spring, and a stop block. The limiting screw is fixedly connected to the pressure-holding block and has a clearance fit with the through hole shaft hole opened in the limiting block. After the limiting spring is sleeved, it maintains continuous pushing on the limiting block. The stop block is connected to one side of the slider and limits the extension and retraction of the limiting block. The limiting block is locked by a pressure-holding locking block to limit the position of the pressure-holding assembly and control the pressure holding force.

[0022] Furthermore, a pressure rod is provided on one side of the pressure holding block, and the pressure rod presses against the passive block to prevent the camera module attracted by the probe rod from directly colliding with the telescopic pin in the camera slot when it is about to enter the camera slot, thus avoiding mistake-proofing through physical structure.

[0023] The beneficial effects of this invention are:

[0024] 1. The eyeglass frame camera module positioning and assembly fixture uses an eyeglass frame positioning carrier to accurately position the eyeglass frame to be assembled with the camera module. In particular, it uses telescopic pins to accurately position the camera slot hole, ensuring that the camera module is accurately aligned with the slot hole, greatly reducing assembly angle and position deviations, and helping the left and right camera modules to be aligned and installed with high precision to meet the quality requirements of mass production of smart glasses.

[0025] 2. The clamping and feeding components of the feeding platform are used to accurately position the camera module to be assembled. The four-step action of adsorption, insertion, assembly and pressure holding is performed by the probing assembly and pressure holding components to fully engage the camera module with the camera slot of the eyeglass frame. After the connecting glue has cured, it is released to fully remove the internal stress of the assembly.

[0026] 3. The clamping and feeding assembly set by the feeding table; after the camera module to be assembled is positioned and gripped by the probe rod, the front clamping block and the rear clamping block slide back to back, thereby releasing the positioning of the camera module. Then the probe rod is inserted straight down into the camera slot hole to complete the installation of the camera module and the eyeglass frame. The positioning is accurate and the control action is reasonable and efficient.

[0027] 4. Press the passive block with the pressure bar. If you forget to press down and lock the passive block with the pressure holding block, you can still press down the passive block with the pressure bar. This will prevent the camera module attached by the probe from colliding directly with the telescopic pin in the camera slot when it is about to enter the camera slot. The physical structure avoids the risk of collision. The foolproof design makes the operation safer. Attached Figure Description

[0049] Please see Figure 1 and Figure 2 This embodiment proposes a positioning and assembly fixture for a camera module inside an eyeglass frame. For the camera slots 202 inside the left and right frame hinges 201 of an eyeglass frame 2 of a smart glasses, adhesive is first applied to the camera slots 202, followed by precise installation of the camera module. After precise assembly, pressure is maintained for a certain period. Once the adhesive has cured, the fixture is removed, resulting in an eyeglass frame 2 assembly with extremely high camera module assembly precision. This assembly includes:

[0050] See Figure 8 The eyeglass frame positioning carrier 1 includes a base 101, a contouring stage 102, and an elastic pressure block 103. (See attached image.) Figure 3 and Figure 7 The telescopic pin 6021 is positioned and fitted inside the camera slot 202 of the eyeglass frame 2 where the camera module needs to be installed. The contouring platform 102 is divided into a left frame section, a bridge section and a right frame section, which can be adapted to the shape and contour of different models of eyeglass frames 2. It is provided with contouring positioning groove 1021 according to the outer contour of the eyeglass frame 2 to be assembled with the camera module, and four sets of elastic pressure blocks 103 are provided around the contouring positioning groove 1021. The elastic pressure blocks 103 press and lock the upper and lower frames of the eyeglass frame 2 that are positioned and stationary therein. Of course, the premise is that the camera slot 202 of the eyeglass frame 2 is accurately positioned by the telescopic pin 6021.

[0051] As a supplement to the solution for eyeglass frame positioning carrier 1, see [reference]. Figure 7The contour stage 102 is provided with a telescopic hole 1022 that mates with the shaft hole of the telescopic pin 6021. The lower end of the telescopic pin 6021 is connected to a passive block 602. The passive block 602 is placed in a rectangular hole in the contour stage 102 and moves up and down, causing the telescopic pin 6021 to be exposed or retracted in the camera slot hole 202. The passive block 602 is pushed by a telescopic spring, so that the telescopic pin 6021 is exposed in the camera slot hole 202 as the initial state, that is, it is in a precise positioning state when the eyeglass frame 2 is placed. Then, the elastic pressure block 103 presses the eyeglass frame 2 tightly.

[0052] The particularly important technical solution is, see [reference] Figure 5 and Figure 6 The passive block 602 is secured or released by the locking module 6. The locking module 6 includes a bolt 601, a lock seat, and a locking spring 603. A manual wrench 6011 is provided on the outside of the bolt 601, and a locking tongue 6012 is provided opposite the passive block 602 to prevent it from sliding upward. When assembling the camera module, the telescopic pin 6021 is kept in the retracted state. The specific operation method is: the bolt 601 is pushed backward, and the locking tongue 6012 blocks the passive block 602 from sliding upward, thereby locking the passive block 602.

[0053] See Figure 4 and Figure 6 The fixture also includes an assembly frame 3, which is positioned and supported above the contour table 102 and includes a support frame 301, a movable locking rod 303, and an assembly plate 302.

[0054] Specifically, see Figure 4 and Figure 8 The lower end face of the support frame 301 is provided with a support limiting pin, which engages with the support bushing provided on the base 101 to position the support frame 301; see reference Figure 2 and Figure 4 The movable locking rod 303 is movably hinged to the outside of the support frame 301 via the hinge block 306. A locking hook is provided at the lower end. The locking hook engages with the support locking block 307 fixed to the outside of the base 101 to lock the assembly frame 3. The assembly plate 302 is mounted on the support frame 301. Positioning bushings 304 and positioning locking blocks 305 are provided on both sides of the assembly plate 302.

[0055] See Figure 9 , Figure 10 and Figure 11 The fixture also includes a feeding platform 4, which is used to position the camera module to be assembled and align the assembly path of the camera module along the axis of the camera slot 202 of the eyeglass frame 2. The feeding platform 4 includes an adjustment plate 401, four positioning pins 413 for alignment, two positioning locking rods 402, elastic pressure clamps and assembly guide seat 406, and a clamping feeding assembly for accurately positioning and placing the camera module.

[0056] Specifically, see Figure 10 The upper surface of the attitude adjustment plate 401 is set at a certain tilt angle, and the normal of the upper surface is parallel to the assembly path of the camera module to be assembled, serving as a positioning reference surface for the assembly action to ensure that the assembly direction of the camera module is directly aligned with the camera slot 202; see reference. Figure 11 The positioning pins 413 are located on both sides of the lower end face of the attitude adjustment plate 401 and are fitted through the shaft hole of the positioning bushing 304. The positioning locking rods 402 are located on both sides of the attitude adjustment plate 401 and are engaged with the positioning locking blocks 305 to achieve the fitting, positioning and locking of the attitude adjustment plate 401 and the assembly plate 302.

[0057] See Figure 9 , Figure 14 , Figure 15 and Figure 16 The probe assembly and pressure holding component 5 is used to complete the precise assembly of the camera module and the eye frame. The probe assembly and pressure holding component 5 includes a slider 501, a pressure holding block 502, a probe rod 507 for precisely guiding the assembly of the camera module, and a pressure holding module for maintaining the stability of the posture before the glue cures after assembly.

[0058] Specifically, see Figure 14 and Figure 15 The slider 501 cooperates with the slide rail 407 and is connected to the pressure holding block 502. The probe rod 507 is connected below the pressure holding block 502. The probe rod 507 has a suction hole 5071 in the center. The upper end of the suction hole 5071 is connected to the suction interface 508, and the suction is performed by an external suction device. The lower end of the suction hole 5071 is connected to a soft adsorption pad 505. After the soft adsorption pad 505 is attached to the surface of the camera module housing, the suction adsorption grips the camera module.

[0059] See Figure 14 and Figure 15 The pressure-holding module is located on the upper end of the pressure-holding block 502 and includes a limiting block 503, a limiting screw 504, a limiting spring, and a stop block 509. The limiting screw 504 is fixedly connected to the pressure-holding block 502 and has a clearance fit with the through hole shaft hole of the limiting block 503. After the limiting spring is inserted, it continuously pushes the limiting block 503. The stop block 509 is connected to one side of the slider 501 and limits the extension and retraction of the limiting block 503. The limiting block 503 is locked by the pressure-holding locking block 403 to limit the position of the pressure-holding assembly and control the pressure holding force.

[0060] See Figure 9 and Figure 10The elastic pressure-holding clamp is equipped with a pressure-holding seat 404, a pressure-holding spring, and a pressure-holding locking block 403 for continuous pressing to complete the assembly of the camera module, as well as a pusher seat 405 for supporting the probe assembly pressure-holding component 5. The pressure-holding locking block 403 is movably hinged to the pressure-holding seat 404 and is pushed by the pressure-holding spring. A lever 4031 is integrally connected to one side of the pressure-holding locking block 403 to facilitate manual control of the pressure-holding locking block 403 to flip. The pusher seat 405 is mounted on both sides of the probe rod 507 and is equipped with a pusher spring 4051 to support the pressure-holding block 502 to prevent the probe assembly pressure-holding component 5 from falling quickly and colliding with the product. The pusher spring 4051 pushes the probe assembly pressure-holding component 5 to reduce its weight and facilitate worker operation.

[0061] Further implementation plans are as follows, see [link / reference] Figure 9 and Figure 14 The assembly guide seat 406 is mounted on the attitude adjustment plate 401, and a slide rail 407 is provided on the inner side, which slides parallel to the assembly path of the camera module. The slide rail 407 cooperates with the probe assembly pressure holding component 5 to realize the linear sliding motion control of the probe assembly pressure holding component 5. A permanent magnet 408 is fixedly connected to the upper end of the assembly guide seat 406. The permanent magnet 408 is attracted and locked with the permanent magnet 408 provided on the slider 501, which facilitates the disassembly and placement of the material release table 4 and protects the probe assembly pressure holding component 5 from shaking and falling off.

[0062] See Figure 11 , Figure 12 and Figure 13 The clamping and feeding assembly is located below the attitude adjustment plate 401 and includes a front positioning block 411, a rear positioning block 412, a front clamping block 416, a rear clamping block 417, an elastic slide rod 415, a sliding sleeve, a front flip handle 409, and a rear flip handle 410 arranged in alignment. The front clamping block 416 achieves distance adjustment by cooperating with the sliding sleeve through the elastic slide rod 415 arranged perpendicular to the inner side of the front positioning block 411, and can automatically reset. The rear clamping block 417 achieves distance adjustment by cooperating with the sliding sleeve through the elastic slide rod 415 arranged perpendicular to the inner side of the rear positioning block 412, and can automatically reset. Because the distance between the two right-angled surfaces of the front flip handle 409 and the rear flip handle 410 and the hinge axis is different, the front clamping block 416 uses the pull rod 414 and the front flip handle 409 to control the telescopic displacement, and the rear clamping block 417 uses the pull rod 414 and the rear flip handle 410 to control the telescopic displacement.

[0063] More specifically, see Figure 12 and Figure 13The inner sides of the front clamping block 416 and the rear clamping block 417 are respectively provided with a front reference groove 4161 and a rear reference groove 4171 facing the camera module to be assembled. The front reference groove 4161 and the rear reference groove 4171 will accurately position the camera module placed on them. After the camera module is adsorbed and grasped by the probe assembly pressure holding component 5, it will be accurately filled and assembled with the camera slot hole 202 of the eyeglass frame 2.

[0064] A further implementation scheme is that a pressure rod 506 is provided on one side of the pressure holding block 502. The pressure rod 506 presses against the passive block 602 to prevent the camera module attracted by the probe rod 507 from directly colliding with the telescopic pin 6021 in the camera slot 202 when it is about to enter the camera slot 202. If the pressure holding locking block 403 is forgotten to press down and lock the passive block 602, the pressure rod 506 can still be used to press down the passive block 602, thereby avoiding direct collision between the camera module attracted by the probe rod 507 and the telescopic pin 6021 in the camera slot 202 when it is about to enter the camera slot 202. The collision risk is avoided by physical structure, which is a foolproof design and makes the operation safer.

[0065] The working principle of the fixture in this embodiment is as follows:

[0066] Place the eyeglass frame 2 into the contour positioning groove 1021, ensuring the camera slot holes 202 on both sides are precisely fitted with the telescopic pins 6021. Then, press the four sets of elastic pressure blocks 103 onto the upper and lower frames of the eyeglass frame 2 to complete the positioning and locking. Install the assembly frame 3, the material placement platform 4, and the probe assembly and pressure holding component 5. After lifting the probe assembly and pressure holding component 5, place the camera module to be installed into the front reference groove 4161 and the rear reference groove 4171 to complete precise positioning. Then, press the probe rod 507 of the probe assembly and pressure holding component 5 downwards until it contacts the... After the camera module is assembled, it is vacuumed and gripped; then the front flip handle 409 and the rear flip handle 410 are turned to release the camera module, and the probe rod 507 continues to descend until it is precisely assembled with the camera slot hole 202 and bonded with the internal adhesive; then the limit block 503 is locked with the elastic pressure clamp and pressure is maintained until the adhesive cures; after curing, the probe rod 507 is removed in sequence, the probe assembly pressure holding component 5 is raised, the assembly frame 3 and the material release table 4 are removed, the elastic pressure block 103 is opened, and the eyeglass frame 2 is taken out. This completes the assembly operation of the camera module and the eyeglass frame 2.

[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.
