Description

Technical Field

[0001] This invention relates to the field of smart glasses assembly fixture technology, specifically to a positioning adhesive carrier for eyeglass frame hinges. Background Technology

[0002] The smart glasses frame has hinge frames on both sides. After the frame hinges are installed, the FPC flexible strip inside the frame needs to pass through the central hole of the frame hinge and extend to the temple. To ensure the airtightness of this location, the central hole of the frame hinge needs to be sealed with adhesive. In current operations, the frame and flexible strip are often supported manually, resulting in insufficient repeatability in positioning. When the adhesive dispensing needle approaches the central hole, the flexible strip is prone to springing back, shifting, or obstructing the needle path, leading to adhesive contamination of the frame, frame hinge, or flexible strip. Especially when the left and right flexible strips need to be flipped to the left and right respectively to avoid obstruction, the lack of a stable flipping limit and locking structure will cause inconsistencies in the dispensing position, amount of adhesive, and sealing shape, affecting the stability of product quality.

[0003] Furthermore, smart eyeglass frames are typically thin and irregularly shaped, making their surfaces easily scratched. The assembly gaps between the hinge frames and the hinges are small, and the flexible strips possess a certain degree of elasticity and resilience. If the frames are only clamped with ordinary fixtures, localized indentations or over-constraint in positioning can easily occur. If the flexible strips are only manually pried open, it's difficult to standardize their flipping direction, flipping angle, and hovering position. When the dispensing needle enters the central hole, it's necessary to simultaneously meet requirements such as frame stability, exposure of the hinge frame hole, keeping the flexible strip away from the needle path, and preventing contamination of surrounding components. Therefore, a specialized carrier is needed that integrates frame positioning, elastic clamping, flexible strip flipping avoidance, endpoint limiting, and locking into a single unit. Summary of the Invention

[0004] The purpose of this invention is to address the issue of FPC flexible strips extending from the frame into the left and right temples of smart glasses. After the upper frame hinges are installed, these strips need to pass through the central hole of the hinge and be sealed with adhesive. The problem we aim to solve is that during adhesive application to the central hole, the frame needs to be precisely positioned, and the left and right flexible strips need to be rotated left and right twice to avoid obstructing the flow of adhesive. This ensures that the dispensing needle can penetrate the central hole without contaminating other components with adhesive. Therefore, a device specifically designed to precisely restrict the left and right rotation of the left and right flexible strips is needed to ensure the smooth application of adhesive to the central hole of the hinge, thereby improving the consistency of the dispensing process and the stability of product quality.

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

[0006] A smart eyeglass frame hinge positioning adhesive carrier is proposed, including a platform, a flip-press component, a contouring platform, a positioning plate, a left wiring limit component, a right wiring limit component, and a locking component;

[0007] The contouring stage is set on the platform to support the eyeglass frame. The contouring stage is provided with positioning posts for positioning the eyeglass frame and hinge frame positioning blocks for positioning the hinge frame.

[0008] The flip-press component is flip-connected to the rear side of the platform and is used to press the eyeglass frame into a positioning state.

[0009] The positioning plate is hinged to the platform via a hinge seat and is used to position the flip-press component, the left cable limiting component, and the right cable limiting component.

[0010] The left and right cable limiting components are used to drive the left and right soft cables to flip left and right to avoid obstacles, and to limit and maintain their positions.

[0011] The locking component is used to lock the left and right cable limit components after the left and right soft cables have completed left and right flipping and avoiding each other.

[0012] Furthermore, the flip-press assembly includes a flip plate, a latch, a locking block, a lower left frame pressing rod, an upper left frame pressing rod, a lower right frame pressing rod, an upper right frame pressing rod, a limiting plate, and a pressing spring. The flip plate is connected to the positioning plate. The latch is located on the front end face of the flip plate and cooperates with the locking block on the platform to lock the flip plate. Each frame pressing rod is positioned by the limiting plate and one end is hinged to the lower end face of the flip plate. They are respectively set to the upper and lower and left and right frame positions of the eyeglasses frame. The pressing spring is set between each frame pressing rod and the flip plate to provide elastic holding force.

[0013] Furthermore, the left cable limiting assembly includes a left turntable, a left limiting module, a left bearing, a left rotating block, a left rotating shaft, and a left limiting block. The left rotating shaft is fitted through the center of the left turntable, and the left rotating shaft is rotatably fitted with the left bearing located on the left side of the positioning plate. The left turntable is equipped with a left wrench and a left connecting rod parallel to the left rotating shaft. The left connecting rod passes through an arc-shaped rotation avoidance hole opened in the positioning plate and connects to the left rotating block. The left connecting rod transmits the rotation of the left turntable to the left rotating block. The left rotating block is located on the positioning plate and is used to limit the start and end points of the left rotating block's rotation in both directions.

[0014] Furthermore, the left limiting module is used to hold and position the left soft board, including a left positioning support block, a left movable pressing block, a left hinge shaft, a limiting pressing groove, and a pressing permanent magnet. The left positioning support block is connected to the left turntable, and the left movable pressing block is movably hinged to the left positioning support block through the left hinge shaft, which can realize up-and-down flipping opening and closing. A limiting pressing groove is opened on the contact surface of the left positioning support block and the left movable pressing block. The limiting pressing groove is used to position the left soft board, and the pressing permanent magnets built into both make the left movable pressing block and the left positioning support block magnetically attracted and pressed together.

[0015] Furthermore, the right cable limiting assembly is based on the same principle as the left cable limiting assembly and has a symmetrical structure, including a right turntable, a right limiting module, a right bearing, a right rotating block, a right rotating shaft, and a right limiting block. The right rotating shaft is fitted through the center of the right turntable, and the right rotating shaft is fitted and rotated with the right bearing located on the right side of the positioning plate. The right turntable is equipped with a right wrench and a right connecting rod parallel to the right rotating shaft. The right connecting rod passes through an arc-shaped rotation avoidance hole opened in the positioning plate and connects to the right rotating block. The right connecting rod transmits the rotation of the right turntable to the right rotating block. The right rotating block is located on the positioning plate and is used to limit the start and end points of the right rotating block's rotation in both directions.

[0016] Furthermore, the left-hand rotating block is equipped with a limiting permanent magnet and a left locking hook, while the right-hand rotating block is structurally symmetrical to the left-hand rotating block and has the same principle and function. The right-hand rotating block is equipped with a limiting permanent magnet and a right locking hook.

[0017] Furthermore, the locking assembly includes a left locking rod for locking the left-hand rotating block, a right locking rod for locking the right-hand rotating block, a movable unlocking block, a stop block, an unlocking spring, a locking spring, and a pin. The inner ends of the left locking rod and the right locking rod are movably hinged by the pin. The outer ends of the left locking rod and the right locking rod are respectively provided with a left locking hook and a right locking hook, and are pushed and assisted by the locking spring, so that the left locking hook of the left locking rod hooks the left locking hook of the left-hand rotating block, and the right locking hook of the right locking rod hooks the right locking hook of the right-hand rotating block.

[0018] Furthermore, the movable unlocking block is used to release the locking state of the left-hand and right-hand rotating blocks. By pressing the middle of the left and right locking rods, the movable unlocking block applies pressure to both, pushing the left locking hook to separate from the left locking hook and the right locking hook to separate from the right locking hook.

[0019] Furthermore, the stop block is positioned above the hinge joint of the left and right locking rods, and is used to push and limit the locking position of the left and right locking rods.

[0020] Furthermore, the unlocking spring is disposed between the stop block and the movable unlocking block, and is used to elastically push the movable unlocking block to reset.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] 1. This intelligent eyeglass frame hinge positioning dispensing carrier uses a contouring stage to support the eyeglass frame in a contoured manner. It uses positioning posts and hinge frame positioning blocks to constrain the main body position and hinge frame position of the eyeglass frame, respectively. Then, a flip-pressing component applies elastic pressure from above, forming a positioning system that combines lower support, planar positioning, and upper pressing. This reduces positional fluctuations caused by manual support and keeps the middle hole of the frame hinge in a stable spatial position relative to the dispensing needle, thereby improving the consistency of dispensing point, dispensing amount, and adhesive sealing shape.

[0023] 2. By using the left and right cable limiting components to clamp and drive the left and right soft cables to rotate along a predetermined arc trajectory, the flexible movement of the soft cables that can be manually moved is transformed into a constrained mechanical movement. This can accurately limit the rotation direction, rotation angle and hovering position of the soft cables, and prevent the soft cables from rebounding, shifting or blocking the entry path of the dispensing needle due to their own elastic restoring force.

[0024] 3. The left flexible busbar is clamped by the left positioning block, left movable pressure block, limiting pressure groove, and pressing permanent magnet, while the right flexible busbar is clamped by the right limiting module symmetrical to it. The limiting pressure groove can restrict the movement of the flexible busbar along the width direction, and the magnetic clamping structure can provide a stable and easy-to-release holding force, so that the force on the flexible busbar is evenly distributed during the flipping process. This can reduce the slippage of the flexible busbar and reduce the risk of FPC conductor bending, indentation, or insulation layer damage caused by rigid clamping.

[0025] 4. The left and right locking rods form hooks with the left and right rotating blocks respectively, and the locking springs provide an elastic force that automatically moves the device towards the locking position. When the left and right soft boards reach the clearance position, the left and right locking hooks can hook onto the left and right locking hooks respectively, thereby resisting the elastic recovery force of the soft boards and the slight vibration during the dispensing process. This eliminates the need for continuous support or force from the operator, thus improving operational stability.

[0026] 5. The movable unlocking block is set to drive the left and right locking rods in a centralized manner, so that the left locking hook and the left locking stop hook, and the right locking hook and the right locking stop hook can be separated synchronously; the unlocking spring pushes the movable unlocking block to reset after the pressing pressure is removed, and the stop block limits the locking position of the two locking rods. This forms a concentrated operation, clear unlocking and automatic reset action logic, which can reduce the misoperation caused by unlocking side by side and shorten the operation cycle.

[0027] 6. The lower left frame pressure bar, upper left frame pressure bar, lower right frame pressure bar, and upper right frame pressure bar apply force to the left, right, upper and lower areas of the eyeglass frame. Each frame pressure bar compensates for the thickness of the frame and the height difference of the curved surface with the help of a pressing spring. The soft pressure head further increases the contact area and reduces the local contact pressure. This can maintain the stability of the frame while reducing the possibility of indentations, scratches, or over-constraint deformation of thin and irregularly shaped frames.

[0028] 7. This invention integrates eyeglass frame positioning, elastic frame holding, soft board clamping, bidirectional flipping avoidance, end position limitation, automatic locking, and centralized unlocking on the same platform. The actions have a clear sequential relationship, which facilitates the formation of a standardized dispensing process. It can be used with manual dispensing devices or automatic dispensing equipment, thereby reducing reliance on operator experience, reducing the probability of glue contaminating eyeglass frames, frame hinges, or soft boards, and improving product yield and mass production stability.

Detailed Implementation

[0039] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. For ease of description, only the parts related to the present invention are shown in the drawings, not the entire structure.

[0040] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. 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.

[0043] like Figures 1 to 4 As shown, the smart eyeglass frame hinge positioning adhesive carrier of this embodiment includes a platform 1, a flip-pressing assembly 2, a contouring platform 3, a positioning plate 4, a left wiring limit assembly 5, a right wiring limit assembly 6, and a locking assembly 7.

[0044] The platform 1 serves as the mounting base for the entire assembly, providing a unified assembly reference for each mechanism and ensuring that each mechanism maintains a defined positional relationship relative to the eyeglass frame 8 to be processed. A hinge seat 101 is located on the rear side of the platform 1, and the positioning plate 4 is hinged to the platform 1 via the hinge seat 101, allowing the positioning plate 4 to open upwards or close downwards around the hinge seat 101. When inserting or removing the eyeglass frame 8, the positioning plate 4 is flipped upwards, creating an operating space above the contour stage 3; during positioning and adhesive application, the positioning plate 4 is flipped downwards to the working position.

[0045] The contouring stage 3 is fixedly mounted on the platform 1. Its supporting surface is designed according to the shape of the corresponding area of ​​the eyeglass frame 8, providing multi-point or planar support for the eyeglass frame 8 after placement. The contouring stage 3 can distribute the overhead pressure to a larger contact area, preventing the thin eyeglass frame 8 from bending due to localized suspension. Positioning posts 301 and hinge frame positioning blocks 302 are provided on the contouring stage 3. The positioning posts 301 cooperate with positioning holes, positioning grooves, or contour references on the eyeglass frame 8 to limit the lateral movement, longitudinal movement, and planar rotation of the eyeglass frame 8 along the surface of the platform 1. The hinge frame positioning blocks 302 are provided corresponding to the hinge frames on both sides of the eyeglass frame 8 to correct the position of the hinge frames and the central holes of the frame hinges. The positioning posts 301 and hinge frame positioning blocks 302 work together to avoid relying solely on the easily deformable outer edge of the frame to determine the glue dispensing hole position, reducing the influence of frame dimensional tolerances on the glue dispensing position.

[0046] Appendix Figure 4 As shown, the eyeglass frame 8 has a lower left frame 804, an upper left frame 805, a left hinge frame 802, a left frame hinge 803, and a left flexible strip 801. The left hinge frame 802 is located at the left end of the eyeglass frame 8, the left frame hinge 803 is fitted inside the left hinge frame 802, and the left flexible strip 801 is led out from inside the eyeglass frame 8 and passes through the middle hole of the left frame hinge 803. The right side of the eyeglass frame 8 has a frame body, hinge frame, frame hinge, and flexible strip corresponding to the functions on the left side. During dispensing, adhesive needs to be applied to the middle hole of the frame hinge to fill the gap between the flexible strip and the hole wall, forming a sealing layer after curing. The adhesive leaves the needle under the output pressure and spreads under the combined action of wetting, surface tension, and gravity. Therefore, before dispensing, the flexible strip needs to be moved out of the needle path while maintaining a reasonable bending radius at the root of the flexible strip.

[0047] See Figure 3 and Figure 4 The flip-press assembly 2 includes a flip plate 201, a latch 202, a locking block 203, a lower left frame pressing rod 204, an upper left frame pressing rod 205, a lower right frame pressing rod 206, and an upper right frame pressing rod 207, a limiting plate 208, and a pressing spring 209. The flip plate 201 is connected to the positioning plate 4 and flips around the hinge seat 101 with the positioning plate 4. The latch 202 is located on the front end face of the flip plate 201, and the locking block 203 is located on the platform 1 at a position corresponding to the latch 202. When the flip plate 201 descends to the working position, the latch 202 and the locking block 203 engage, and the mechanical engagement between them restricts the flip plate 201 from lifting upward, thereby keeping the flip-press assembly 2 closed. When it is necessary to remove the part, the latch 202 and the locking block 203 are released, and the flip plate 201 and the positioning plate 4 can be flipped upward.

[0048] One end of each of the lower left frame retainer 204, upper left frame retainer 205, lower right frame retainer 206, and upper right frame retainer 207 is hinged to the lower end face of the flip plate 201, allowing each retainer to swing within a set angle range. A limiting plate 208 is positioned adjacent to each retainer to limit its lateral position and swing range, preventing it from deviating from its corresponding frame part after repeated opening and closing. The lower left frame retainer 204 corresponds to the lower left frame 804, and the upper left frame retainer 205 corresponds to the upper left frame 805; the lower right frame retainer 206 and upper right frame retainer 207 correspond to the lower and upper frame bodies on the right side of the eyeglass frame 8, respectively.

[0049] The lower left frame retainer 204 has a soft pressure head 2041 at its holding end, and the other frame retainers can also use the same soft structure. The soft pressure head 2041 can be made of silicone, rubber, polyurethane elastomer, or other materials that are not easily scratched on the frame surface. When the soft pressure head 2041 is compressed, it undergoes a suitable amount of elastic deformation, thereby increasing the actual contact area with the frame surface. According to the principle that pressure equals the ratio of force to area, when the holding force is basically the same, increasing the contact area can reduce local pressure peaks and reduce indentations or scratches on the frame surface.

[0050] The pressing springs 209 are positioned between each frame retaining rod and the flip plate 201. When the flip plate 201 closes downwards, the holding ends of each frame retaining rod first contact the eyeglass frame 8. As the flip plate 201 continues to descend, the frame retaining rods swing at a small angle relative to the flip plate 201, compressing the pressing springs 209. Within the elastic limit, the elastic force of the pressing springs 209 increases with the amount of compression, thereby providing a downward elastic holding force to the corresponding frame retaining rods. Since the four frame retaining rods can float independently, even if there are small thickness tolerances or height differences in different areas of the eyeglass frame 8, they can be independently compensated by the corresponding pressing springs 209, preventing the rigid plate from only pressing the highest area or causing excessive pressure on the higher areas.

[0051] After the flip-press assembly 2 is closed, the lower left frame pressure bar 204, upper left frame pressure bar 205, lower right frame pressure bar 206, and upper right frame pressure bar 207 apply downward pressure to the eyeglass frame 8, respectively. The contour stage 3 provides a supporting reaction force in the opposite direction, while the positioning post 301 and the hinge frame positioning block 302 restrict the horizontal movement of the eyeglass frame 8. Thus, the eyeglass frame 8 is constrained in both the vertical and horizontal directions, but the elastic floating of each pressure bar allows the frame to retain the necessary small dimensional compensation, thereby avoiding obvious over-constraint.

[0052] like Figures 5 to 8As shown, the left cable guide assembly 5 includes a left turntable 501, a left limit module 502, a left bearing 503, a left rotating block 504, a left rotating shaft 505, and a left limit block 507. The center of the left turntable 501 is fitted onto the left rotating shaft 505, which is housed within the left bearing 503 on the left side of the positioning plate 4. The left bearing 503 provides radial support to the left rotating shaft 505 and reduces rotational resistance through rolling or low-friction sliding contact, enabling the left turntable 501 to rotate smoothly around a defined axis while minimizing the impact of shaft wobble on the accuracy of the cable guide's flipping endpoint.

[0053] A left wrench 5011 and a left connecting rod 5012 are provided on the left turntable 501. The left wrench 5011 is used for the operator to apply force. When the operator applies a tangential force to the left wrench 5011, this force generates a torque relative to the left rotating shaft 505, thereby driving the left turntable 501 to rotate. The left connecting rod 5012 is arranged parallel to the left rotating shaft 505, with one end connected to the left turntable 501 and the other end passing through the arc-shaped rotation clearance hole 506 opened on the positioning plate 4 and connected to the left rotating block 504. When the left turntable 501 rotates, the left connecting rod 5012 moves in an arc with the left turntable 501, and transmits the angular displacement and torque of the left turntable 501 to the left rotating block 504.

[0054] The arc-shaped rotating clearance hole 506 is set with the axis of the left rotating shaft 505 as the corresponding center. Its arc trajectory is adapted to the movement trajectory of the left connecting rod 5012, so that the left connecting rod 5012 will not interfere with the positioning plate 4 during rotation. The arc length of the arc-shaped rotating clearance hole 506 corresponds to the required flipping angle, and its two ends can also form a travel boundary for the left connecting rod 5012, thereby cooperating with the left limit block 507 to prevent the left turntable 501 and the left rotating block 504 from exceeding the designed rotation angle. This mechanical trajectory constraint can ensure that the start and end positions of each flip are consistent.

[0055] See Figure 2 The left limiting module 502 is fixed to the left turntable 501 and includes a left positioning block 5021, a left movable pressure block 5022, a left hinge shaft 5023, and a pressing permanent magnet 5025. The left positioning block 5021 supports the left flexible board 801 from below. The left movable pressure block 5022 is hinged to the left positioning block 5021 via the left hinge shaft 5023, allowing the left movable pressure block 5022 to open upwards or close downwards around the left hinge shaft 5023. A limiting pressure groove 5024 is formed between the relatively mating surfaces of the left positioning block 5021 and the left movable pressure block 5022. The width and depth of the limiting pressure groove 5024 are adapted to the shape of the left flexible board 801 and are reserved with the assembly clearance required to avoid excessive compression of the FPC flexible board.

[0056] When clamping the left flexible busbar 801, first flip the left movable pressure block 5022 upwards, smoothly place the left flexible busbar 801 into the limiting pressure groove 5024, and then close the left movable pressure block 5022 downwards around the left hinge axis 5023. The left positioning support block 5021 and the left movable pressure block 5022 are equipped with pressing permanent magnets 5025 with attracted polarities. When the two are close together, the pressing permanent magnets 5025 generate a magnetic attraction force, keeping the left movable pressure block 5022 in the closed position. This magnetic attraction force provides a normal holding force to the left flexible busbar 801 through the left movable pressure block 5022. The sidewall of the limiting pressure groove 5024 restricts the left flexible busbar 801 from moving along the width direction, while the frictional force generated between the groove surface and the surface of the flexible busbar restricts the left flexible busbar 801 from sliding along the length direction.

[0057] The holding force provided by the permanent magnet 5025 should be greater than the tendency to disengage and the elastic recovery force generated when the left flexible busbar 801 flips over, but it should not be so great that the left movable pressure block 5022 is difficult to open or that the left flexible busbar 801 will have an irreversible indentation. Using a magnetic clamping method eliminates the need for repeated tightening of screws, improving loading and unloading efficiency; when it is necessary to release the left flexible busbar 801, simply overcome the magnetic attraction and flip the left movable pressure block 5022 upwards.

[0058] The left-hand rotating block 504 is equipped with a limiting permanent magnet 5041 and a left locking hook 5042, and the left limiting block 507 is located at the rotation termination position of the left-hand rotating block 504. When the left wrench 5011 is turned, the left turntable 501 drives the left limiting module 502 and the clamped left flexible board 801 to rotate synchronously, and the left connecting rod 5012 simultaneously drives the left-hand rotating block 504 to rotate. The left flexible board 801 thus makes a controlled arc movement around the left rotating shaft 505 with the left limiting module 502, instead of being locally bent by the operator directly pulling the free end of the flexible board. By reasonably setting the distance between the left rotating shaft 505 and the allowable bending area of ​​the left flexible board 801, the bending radius of the left flexible board 801 can be made greater than its minimum allowable bending radius, reducing the risk of fatigue fracture and interlayer delamination of the copper foil inside the FPC.

[0059] When the left-hand rotating block 504 reaches the predetermined end position, it abuts against the left limiting block 507. Simultaneously, the left connecting rod 5012 can also approach the corresponding end of the arc-shaped rotating clearance hole 506, thereby preventing the mechanism from continuing to rotate. The limiting permanent magnet 5041 generates attraction with the corresponding magnetic component, providing end-position attraction and a tactile feel for the left-hand rotating block 504, and preventing the left-hand rotating block 504 from leaving the end position due to the elastic restoring force of the left soft strip 801 before the locking assembly 7 is fully engaged. The left limiting block 507 plays the main mechanical stopping role, while the limiting permanent magnet 5041 mainly plays an auxiliary holding role. The combination of the two avoids relying solely on magnetic force to determine the flipping angle.

[0060] See Figure 1 and Figure 7The right cable limiting assembly 6 and the left cable limiting assembly 5 are arranged symmetrically with the center of the vehicle as the reference. The right cable limiting assembly 6 includes a right turntable 601, a right limiting module 602, a right bearing, a right rotating block 604, a right rotating shaft, a right limiting block 607, and a right connecting rod and an arc-shaped rotating clearance hole corresponding to the left side. A right wrench 6011 is provided on the right turntable 601. The right positioning support block 6021 in the attached reference numerals table serves as the lower support of the right limiting module 602, and its structure and function correspond to the left positioning support block 5021. The right limiting module 602 also includes a right movable pressure block 6022 and a right hinge shaft 6023, and can be provided with limiting pressure grooves and pressing permanent magnets based on the same principle as the left side.

[0061] When clamping the right flexible busbar, flip the right movable pressure block 6022 upward around the right hinge shaft 6023, place the right flexible busbar smoothly in the corresponding slot of the right positioning support block 6021, and then close the right movable pressure block 6022 downward. The right movable pressure block 6022 remains closed under the magnetic attraction of the pressing permanent magnet, forming a vertical pressing and width-direction limit on the right flexible busbar. When the operator turns the right wrench 6011, the right turntable 601 rotates around the right rotating shaft, which is supported by the right bearing; the right connecting rod passes through the corresponding arc-shaped rotation clearance hole on the positioning plate 4 and connects to the right rotating block 604, so that the right rotating block 604 rotates synchronously with the right turntable 601.

[0062] The right limiting block 607 is used to limit the forward or reverse rotation endpoint of the right-hand rotating block 604. The right-hand rotating block 604 is equipped with a right locking hook 6042 and can be equipped with a magnetic end-position holding component with the same principle as the limiting permanent magnet 5041. When the right limiting module 602 rotates with the right turntable 601, it drives the right soft board to flip to the left or right along a predetermined arc, so that the right soft board is away from the dispensing needle path of the middle hole of the right frame hinge. The left and right sets of cable limiting components are set separately, so that the left soft board 801 and the right soft board can be flipped independently according to the dispensing sequence; the left and right structures adopt a symmetrical design, which can keep the operation mode, flipping angle and force relationship of both sides consistent.

[0063] In one dispensing process, the left ribbon cable limiting component 5 first rotates the left flexible ribbon cable 801 from its initial position in the first direction, exposing the central hole of the left frame hinge 803, allowing the dispensing needle to enter from the first direction. After completing the corresponding dispensing, the left flexible ribbon cable 801 can be rotated in the opposite direction to a second clearance position according to the spatial requirements of another dispensing position or needle insertion direction. The right ribbon cable limiting component 6 rotates the right flexible ribbon cable in the same way to perform a mirror action. Since the rotation angle of the flexible ribbon cable is determined by mechanical structures such as the arc-shaped rotating clearance hole 506, the left limiting block 507, and the right limiting block 607, there is no need for the operator to visually judge the endpoint.

[0064] like Figure 8 and Figure 9As shown, the locking assembly 7 includes a left locking lever 701, a right locking lever 702, a movable unlocking block 703, a stopping block 704, an unlocking spring 705, a locking spring 706, and a pin 707. The left locking lever 701 is used to lock the left-hand rotating block 504, and a left locking hook 7011 is provided at one of its outer ends; the right locking lever 702 is used to lock the right-hand rotating block 604, and a right locking hook 7021 is provided at one of its outer ends. The inner ends of the left locking lever 701 and the right locking lever 702 are movably hinged by the pin 707, allowing the two locking levers to swing within a set range around the pin 707 respectively.

[0065] The locking spring 706 applies an elastic force to the left locking lever 701 and the right locking lever 702 in a direction towards locking, causing the left locking hook 7011 to maintain its tendency to move towards the left locking hook 5042, and the right locking hook 7021 to maintain its tendency to move towards the right locking hook 6042. When the left rotating block 504 turns to the locking position, the guide ramp of the left locking hook 5042 first contacts the left locking hook 7011 and pushes the left locking lever 701 to swing temporarily in the unlocking direction, further compressing the locking spring 706. After the left locking hook 5042 passes the left locking hook 7011, the locking spring 706 releases part of its elastic potential energy and pushes the left locking lever 701 to swing back, causing the left locking hook 7011 to enter the rear side of the left locking hook 5042, forming a mechanical engagement.

[0066] When the right-hand rotating block 604 reaches the locking position, the right locking hook 6042 pushes the right locking hook 7021 to temporarily retract using the same principle. After the right locking hook 6042 passes the right locking hook 7021, the locking spring 706 pushes the right locking rod 702 to swing back, causing the right locking hook 7021 to hook the right locking hook 6042. The left locking hook 7011 and the right locking hook 7021 respectively bear the opposite force generated by the elastic restoring force of the soft pad through the hook surface, geometrically preventing the left-hand rotating block 504 and the right-hand rotating block 604 from rotating in opposite directions. This locking method mainly relies on the hook structure to form mechanical constraints, rather than simply relying on contact friction, thus achieving a more stable end-position holding effect.

[0067] The stop block 704 is positioned above the hinged positions of the left locking rod 701 and the right locking rod 702, and abuts or has a clearance fit with the corresponding parts of the two locking rods. When the locking spring 706 pushes the two locking rods back to the locking position, the stop block 704 limits their maximum swing position, so that the left locking hook 7011 and the right locking hook 7021 stop at the design heights of the corresponding left locking hook 5042 and right locking hook 6042, respectively. This prevents the two locking rods from swinging back excessively and getting stuck with the rotating block, and ensures that the guide ramps can reliably contact each other during the next locking.

[0068] See Figure 9The movable unlocking block 703 is positioned to act simultaneously on the middle of the left locking lever 701 and the right locking lever 702. When unlocking is required, the operator presses the movable unlocking block 703, which applies pressure to both the left and right locking levers 701 and 702 respectively. This causes the two levers to overcome the force of the locking spring 706 and swing around the pin 707 in the direction of disengagement. The left locking hook 7011 thus disengages from the left locking hook 5042, and the right locking hook 7021 simultaneously disengages from the right locking hook 6042, allowing the left and right rotating blocks 504 and 604 to regain their free rotation.

[0069] The unlocking spring 705 is positioned between the stop block 704 and the movable unlocking block 703. When the movable unlocking block 703 is pressed, the unlocking spring 705 is compressed and stores elastic potential energy. After the operator removes the pressing force, the unlocking spring 705 releases the elastic potential energy, pushing the movable unlocking block 703 back to the unpressed position. After the movable unlocking block 703 resets, it no longer continuously presses on the left locking lever 701 and the right locking lever 702. The two locking levers can then return to the locking position defined by the stop block 704 under the action of the locking spring 706, ready for the next automatic locking.

[0070] The complete working process of this embodiment is as follows: Before the operation begins, the latch 202 is separated from the locking block 203, the flip plate 201 and the positioning plate 4 are flipped upward around the hinge seat 101, and the left limiting module 502 and the right limiting module 602 are confirmed to be in the initial position for easy loading. The eyeglass frame 8 is placed on the contour stage 3, so that the corresponding positioning parts of the eyeglass frame 8 fit into or abut against the positioning post 301, and the left hinge frame 802 and the corresponding right hinge frame are respectively engaged with the hinge frame positioning block 302. At this time, the lower left frame 804 and the upper left frame 805 are supported by the corresponding area of ​​the contour stage 3, and the middle hole of the left frame hinge 803 is near the preset glue application position.

[0071] Next, open the left movable pressure block 5022, straighten the left flexible strip 801 passing through the middle hole of the left frame hinge 803, and place it into the limiting pressure groove 5024. Then, close the left movable pressure block 5022 downwards around the left hinge axis 5023, and press the permanent magnet 5025 to make the left movable pressure block 5022 adhere to the left positioning support block 5021. Open the right movable pressure block 6022 in the same way, place the right flexible strip on the right positioning support block 6021, and then close the right movable pressure block 6022 around the right hinge axis 6023. When clamping, avoid forcibly twisting the flexible strip, and retain a natural transition arc at the root of the flexible strip to prevent the flipping action from pulling the flexible strip in the middle hole of the frame hinge.

[0072] After the left and right soft-mounted frames are clamped, the positioning plate 4 and the flip plate 201 are flipped downwards. The lower left frame pressure bar 204, the upper left frame pressure bar 205, the lower right frame pressure bar 206, and the upper right frame pressure bar 207 contact the eyeglass frame 8 sequentially or almost simultaneously. The flip plate 201 is closed further, causing the pressing spring 209 to generate the set compression amount, and then the latch 202 is engaged with the locking block 203. The soft pressure head 2041 is in contact with the surface of the eyeglass frame, and the elastic pressure presses the eyeglass frame 8 against the contour stage 3, while the positioning post 301 and the hinge frame positioning block 302 prevent the eyeglass frame 8 from shifting horizontally.

[0073] Before applying adhesive to the left side, the operator holds the left wrench 5011 and applies force to rotate the left turntable 501. The left turntable 501 drives the left rotating block 504 to rotate via the left connecting rod 5012, while simultaneously causing the left limiting module 502 to rotate the left flexible board 801 around the left rotating shaft 505. The left connecting rod 5012 moves within the arc-shaped rotating clearance hole 506. When it reaches the predetermined end point, the left limiting block 507 forms a mechanical stop on the left rotating block 504, and the limiting permanent magnet 5041 provides auxiliary end-position attraction. Subsequently, the left locking hook 5042 passes over the left locking hook 7011 and is hooked by the left locking hook 7011. Even if the operator removes the force applied to the left wrench 5011, the left flexible board 801 can still remain in a clearance position away from the needle path.

[0074] On the right side, according to process requirements, the right turntable 601 and the right limit module 602 are driven to rotate by the right wrench 6011, causing the right soft board to flip in a predetermined direction. After the right rotating block 604 reaches the endpoint determined by the right limit block 607, the right locking hook 6042 is hooked by the right locking hook 7021, thus maintaining the right soft board in a avoidance state. After both the left and right soft boards have completed the avoidance, the glue dispensing needle can approach the middle hole of the frame hinge without touching the soft board.

[0075] The dispensing equipment outputs adhesive into the central hole according to the set pressure, time, or dispensing volume. Under the output pressure, the adhesive enters the hole and spreads into the gap by wetting the hole wall and the surface of the flexible strip. Surface tension causes the adhesive to form a continuous sealing body. The eyeglass frame 8 is held in place by the contour stage 3, the positioning post 301, the hinge frame positioning block 302, and the flip-pressing assembly 2, so the central hole will not be significantly displaced during the dispensing process. The left and right flexible strips are kept outside the needle path by the left ribbon cable limiting assembly 5 and the right ribbon cable limiting assembly 6, which can reduce the probability of the needle colliding with the flexible strips and the adhesive being carried to non-target areas by the flexible strips.

[0076] When the process requires the same flexible board to avoid obstacles in two directions, after applying adhesive in the first direction, press the movable unlocking block 703 to separate the corresponding locking hook from the locking hook. Then, use the left wrench 5011 or the right wrench 6011 to smoothly rotate the corresponding limit module to the other end. The corresponding limit structure determines the second flipping endpoint, and then the second adhesive application is performed. During the flipping process, the force should be applied continuously and smoothly to avoid using inertia to cause the rotating block to violently hit the limit block, thereby reducing the impact on the mechanism and the instantaneous bending stress of the flexible board.

[0077] After dispensing, wait for the adhesive to reach a state where it is not easily dripping or stringing before unlocking and resetting to prevent the soft board from returning to its original position too early and disturbing the still-unset adhesive. When removing the part, press the movable unlocking block 703 to cause the left locking lever 701 and right locking lever 702 to swing around the pin 707, releasing the engagement between the left locking hook 7011 and the left locking stop hook 5042, and between the right locking hook 7021 and the right locking stop hook 6042. Then, operate the left wrench 5011 and the right wrench 6011 respectively to return the left turntable 501 and the right turntable 601 to their loading / unloading positions.

[0078] After the pressure on the movable unlocking block 703 is removed, the unlocking spring 705 pushes the movable unlocking block 703 to reset, and the locking spring 706 pushes the left locking rod 701 and the right locking rod 702 back to the locking position defined by the stop block 704. Then open the left movable pressing block 5022 and the right movable pressing block 6022 to release the clamping of the left and right soft strips; release the latch 202 from the locking block 203, and flip the flip plate 201 and the positioning plate 4 upward around the hinge seat 101, so that the eyeglass frame 8 can be separated from the positioning post 301 and the hinge frame positioning block 302 and smoothly removed from the contour table 3.

[0079] To ensure positioning accuracy during long-term use of the vehicle, the platform 1, positioning plate 4, left turntable 501, right turntable 601, left rotating block 504, right rotating block 604, and each locking rod can be made of metal or engineering plastic with sufficient rigidity and wear resistance. The parts in contact with the eyeglass frame 8 and the flexible strip should be fitted with rounded corners, soft pads, or low-friction protective layers. The clearance between the left bearing 503 and the right bearing should balance smooth rotation and end-position repeatability. A reasonable clearance should be maintained between the left connecting rod 5012, the right connecting rod, and the corresponding arc-shaped rotation clearance hole to avoid motion interference.

[0080] The stiffness and preload of the pressing spring 209, locking spring 706, and unlocking spring 705 can be selected based on the structural strength of the eyeglass frame 8, the elastic restoring force of the soft strips, and the feel of operation. The magnetic force of the pressing permanent magnet 5025 and the limiting permanent magnet 5041 should achieve a balance between reliable retention and easy manual opening. Through the above-mentioned structure and parameter coordination, this embodiment can complete the repeated positioning of the eyeglass frame 8, the controlled flipping of the left and right soft strips, the endpoint limiting, automatic locking, centralized unlocking, and the stable adhesive sealing of the middle hole of the frame hinge.

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.
