Description

Technical Field

[0001] This invention relates to the field of AR glasses manufacturing, and more specifically to an integrated device for dispensing and curing AR glasses lenses and a dispensing, curing and bonding method. Background Technology

[0002] AR glasses, as a core product integrating augmented reality technology and smart wearable functions, and AR prescription glasses, as a subcategory of AR glasses, integrate myopia correction optical components while retaining the core AR functions. By precisely bonding and assembling customized myopia lenses to the AR glasses body, they meet the AR usage needs of myopic individuals, becoming one of the mainstream products in the consumer-grade smart wearable market. The bonding and assembly precision of the optical lenses and frames directly determines the product's image quality, structural stability, and wearing experience. In the industrial production of AR glasses, edge adhesive application to the optical lenses and the pressing and curing of the lenses and frames are core assembly processes. The curing fixture is the key carrier for achieving adhesive support and pressing positioning; its structural design directly affects the lens positioning accuracy, pressing effect, and final product yield.

[0003] In existing AR glasses lens assembly processes, the execution devices for dispensing, curing, and pressing are independent, lacking a unified time-series control system. Process switching relies on manual operation, resulting in low production efficiency and susceptibility to lens positioning errors due to human intervention. Furthermore, pressing and curing occur directly after dispensing, without pre-curing and shaping the optical adhesive. This leads to adhesive overflow and uneven distribution during pressing, resulting in low lens-frame bonding accuracy and assembly defects such as delamination and warping, impacting product quality. Simultaneously, the existing assembly devices lack coordinated operation logic; the lens positioning and adhesive sleeve limiting structures lack compatibility with subsequent processes, hindering automated continuous assembly and failing to meet the demands of mass production for AR glasses. Moreover, existing devices lack avoidance designs for frame structures, easily interfering with frame protrusions and clips during pressing, further reducing assembly accuracy. Additionally, the lack of a unified cleanroom environment allows impurities to adhere, affecting the imaging effect and bonding quality of the optical lenses. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide an integrated device for dispensing and curing AR glasses lenses and a dispensing, curing and bonding method to overcome the above-mentioned defects in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An integrated device for dispensing and curing AR glasses lenses includes a frame and a central control module. The frame is equipped with a lens fixture, a dispensing module, a curing module, and a pressing module. The central control module is signal-connected to the lens fixture, the dispensing module, the curing module, and the pressing module, respectively. Each module is equipped with a status sensor. The central control module receives the action feedback signals of each module through the status sensors and triggers the linkage action of each module according to a preset process sequence. The lens fixture includes a lower lens mold, a middle lens mold, and a connecting assembly. The lower lens mold supports the optical lens. The middle lens mold is parallel to the lower lens mold and has a positioning groove to restrict the movement of the optical lens. The connecting assembly is located between the middle lens mold and the lower lens mold, allowing the middle lens mold to move closer to the lower lens mold when compressed. The dispensing module performs dispensing operations on the dispensing area of ​​the optical lens and sends a dispensing completion signal to the central control module via a status sensor after dispensing is completed. The curing module is fixedly connected to the lower lens mold and receives a trigger signal from the central control module. It pre-cures the optical adhesive after dispensing and can switch to a secondary curing mode during pressing. The pressing module receives a trigger signal from the central control module, compresses the lens fixture to make the optical lens and AR glasses frame fit together, and sends a pressing completion signal to the central control module via a status sensor after pressing, triggering the secondary curing action of the curing module.

One end of the guide post is fixedly connected to the middle mold of the lens, and the other end of the guide post is slidably connected to the lower mold of the lens. The elastic reset member is sleeved on the guide post, and both ends of the elastic reset member abut against the middle mold of the lens and the lower mold of the lens, respectively. The end of the guide post away from the middle mold of the lens passes through the lower mold of the lens and forms a limiting head, which is used to limit the sliding stroke of the guide post.

[0008] In this invention, preferably, the lower lens mold includes a lower template and a support insert. The lower template is slidably connected to the guide post, and the support insert and the lower template are detachably connected. The shape of the support surface of the support insert is adapted to the shape of the optical lens. The support insert is provided with a plurality of suction cups, which are signal-connected to the central control module and used to adsorb and fix the optical lens and receive signals from the central control module to complete the adsorption and release.

[0009] In this invention, preferably, the support insert is made of a light-transmitting material, and the light emission direction of the curing module is toward the support insert, so that the light emitted by the curing module can penetrate the support insert and irradiate the dispensing area of ​​the optical lens.

[0010] In this invention, preferably, the dispensing module includes a dispensing device, a driving mechanism, and a support mechanism. The driving mechanism is signal-connected to a central control module and is used to drive the dispensing device to move in three-dimensional space. The support mechanism is disposed between the driving mechanism and the dispensing device. The dispensing device includes a glue tube. The support mechanism includes a main support, an upper support assembly, a lower support assembly, and a positioning assembly. The main support is installed at the end of the driving mechanism. The upper support assembly and the lower support assembly are respectively connected to the main support and are used to install the two ends of the glue tube. The positioning assembly is disposed on the upper support assembly and the lower support assembly, and the positioning assembly cooperates with the outer wall of the glue tube to limit the radial position of the glue tube.

[0011] In this invention, preferably, the positioning component includes an upper clamping block and a lower clamping block. The upper clamping block has an upper positioning hole that slides with the outer cylindrical surface of the rubber tube, and the lower clamping block has a lower positioning hole that slides with the outer cylindrical surface of the rubber tube. The upper positioning hole and the lower positioning hole are arranged coaxially.

[0012] In this invention, preferably, the curing module includes a UV lamp assembly and a heat dissipation component. The UV lamp assembly is signal-connected to the central control module and is used to receive signals from the central control module to switch between pre-curing and secondary curing modes. The heat dissipation component is fitted to the UV lamp assembly and is used to dissipate heat from the UV lamp assembly.

[0013] In this invention, preferably, the pressing module includes a sliding guide post and a pressure plate. The sliding guide post is fixedly connected to the frame, and the pressure plate is slidably connected to the sliding guide post. The pressing module also includes a power drive component, which is connected to the central control module and the pressure plate respectively, and is used to drive the pressure plate to make vertical lifting and lowering movements along the sliding guide post.

[0014] In this invention, preferably, the lens mold has a plurality of clearance grooves, which are connected to the positioning grooves. The shape of the clearance grooves is adapted to the contour of the AR glasses frame. The frame is also provided with an AC fan filter unit, which is signal-connected to the central control module and is used to deliver clean air to the working area of ​​the device.

[0015] A method for dispensing, curing, and bonding AR glasses lenses using any of the devices described above, comprising: S1. Loading and positioning: The optical lens is placed on the support insert of the lower mold of the lens. The edge of the lens is embedded in the positioning groove, triggering the loading position signal. After receiving the signal, the central control module starts the suction cup to adsorb and fix the optical lens, and at the same time starts the AC fan filter unit. S2. Dispensing operation: After receiving the loading and positioning completion signal, the central control module triggers the dispensing module to start, and the drive mechanism drives the dispensing device to move, completing the dispensing operation of the optical lens on the preset trajectory. S3, Pre-curing: After the dispensing module completes dispensing, it sends out a dispensing completion signal. After receiving the signal, the central control module triggers the curing module to start pre-curing and at the same time triggers the dispensing module to reset to the initial position. S4, Frame Positioning: Place the AR glasses frame on top of the pre-cured optical lenses. The protruding structure of the frame is embedded in the clearance groove, triggering the frame positioning signal and feeding back to the central control module. S5, Pressing Trigger: After the central control module receives the frame positioning signal, it triggers the pressing module to start. The power drive component drives the pressure plate to press down, pushing the middle mold of the lens closer to the lower mold of the lens, so that the optical lens and the frame gradually fit together. S6. Synchronous secondary curing: After the pressure plate is pressed down to the preset position, a signal indicating that the pressure is in place is fed back. After receiving the signal, the central control module triggers the curing module to switch to secondary curing mode. The pressure module maintains the pressure state, realizing the bonding and pressure maintenance of the optical lens and the frame and the secondary curing of the optical adhesive. S7. Reset and unloading: After the curing module completes the secondary curing, it sends a curing completion signal. After receiving the signal, the central control module triggers the pressing module to reset, and then triggers the suction cup to release the optical lens. The elastic reset component pushes the lens mold back to the initial position, and the assembled AR glasses are taken out. The device returns to the initial standby state.

[0016] The beneficial effects of this invention are: 1. The AR glasses lens dispensing and curing integrated device and method of the present invention establishes a full-module time-sequential linkage system through a central control module, realizing automated continuous operation of dispensing, pre-curing, pressing, and secondary curing. It specifically solves many technical defects of traditional AR glasses lens assembly and is suitable for industrial mass production needs. The device uses the central control module as its core, combined with the status sensors of each module to achieve action feedback and sequential triggering, replacing traditional manual process switching, significantly reducing manual intervention, improving overall production efficiency, avoiding positioning deviations caused by manual operation, and ensuring the accuracy of each process connection. The lens fixture forms a dual positioning through positioning grooves and suction cups, combined with a light-transmitting and detachable support insert, which not only prevents lens displacement during operation but also provides a path for the curing light. Furthermore, the support insert can be adapted to different lens specifications, improving the device's versatility. The elastic connecting component works with the pressing module to achieve flexible pressing, avoiding rigid compression damage to the optical lenses. The frame clearance groove design effectively prevents pressing interference, further ensuring bonding accuracy.

[0017] 2. The coaxial positioning component of the dispensing module enables precise radial positioning of the glue tube, avoiding trajectory deviation caused by glue tube displacement during dispensing, ensuring uniform glue layer distribution, and laying the foundation for subsequent bonding and curing; the curing module can switch between pre-curing and secondary curing modes. After dispensing, the optical glue is pre-cured and shaped, which solves the glue layer flow and overflow problem caused by traditional direct pressing from the root, preventing glue from contaminating the optical area. During secondary curing, it is combined with pressing and pressure holding to effectively avoid debonding and warping problems, and improve the bonding firmness between the lens and the frame.

[0018] 3. The matching bonding method and device are highly compatible, executing each step in a fixed process sequence. This achieves deep integration of device operation and process requirements, making the coordinated operation of pre-curing, pressing, and secondary curing more orderly and ensuring the stability of assembly quality. Simultaneously, the AC fan filter unit on the frame provides a clean environment for operation, preventing impurities from adhering and affecting the imaging effect of optical lenses and bonding quality, further improving product yield.

[0019] 4. This invention organically combines the device structure and process method, realizing the automation, precision and efficiency of AR glasses lens assembly. It not only improves the assembly accuracy and quality stability of the product, but also enhances the versatility and adaptability of the device, significantly reducing labor costs and product scrap rate in the production process, and has good industrial application value.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please also see Figures 1 to 9 This embodiment provides an integrated device for dispensing and curing AR glasses lenses and a dispensing, curing and bonding method using the device. It is described in further detail here. The present invention realizes the time-series linkage control of each module through a central control module, and completes the integrated automated operation of dispensing, pre-curing, frame bonding and secondary curing of AR glasses lenses. It effectively solves the problems of easy glue overflow, low bonding accuracy and poor process coordination in the prior art by direct pressing, and is suitable for the industrial mass production needs of AR glasses.

[0026] The AR glasses lens dispensing and curing integrated device of this embodiment includes a frame 1 and a central control module. The frame 1 is constructed of aluminum alloy profiles, featuring high structural strength and convenient assembly and disassembly, providing a stable installation foundation for each functional module. The central control module is a PLC or microcontroller control module, serving as the core control hub of the device. It is integrated into the control area of ​​the frame 1 and establishes signal connections with the lens fixture 2, dispensing module 3, curing module 4, and pressing module 5 set on the frame 1. Each of the lens fixture 2, dispensing module 3, curing module 4, and pressing module 5 is equipped with a corresponding status sensor, which is a proximity switch, limit switch, or inductive sensor. This sensor is used to detect the action status of each module in real time and feed back electrical signals to the central control module. The central control module has a preset process operation sequence stored inside. By receiving the action feedback signals from each module, it triggers the linkage action of each module in sequence, realizing the automated continuous operation of the device without manual intervention in the switching of each process.

[0027] The lens fixture 2 on the frame 1 includes a lower lens mold 21, a middle lens mold 22, and connecting components. The lower lens mold 21 serves as a basic support structure for stably supporting the optical lens. It includes a lower template 211 and a support insert 212. The lower template 211 is fixedly connected to the frame 1, and the support insert 212 is detachably connected to the lower template 211, allowing for quick disassembly and replacement via bolts. The upper surface of the support insert 212 is a support surface that conforms to the contour of the back of the optical lens, ensuring precise contact with the lens and preventing deformation during subsequent operations. It can also be adjusted according to... The support insert 212 is replaced with the corresponding support insert 212 according to the optical lens of AR glasses of different specifications, thereby improving the versatility of the device. The support insert 212 is made of light-transmitting materials such as quartz glass and high-transmittance optical resin, which provides a path for light to irradiate the curing module 4. The support insert 212 is also provided with several suction cups 213. The suction cups 213 are connected to the central control module and are controlled by the central control module to realize negative pressure adsorption and adsorption release, which is used to firmly fix the optical lens on the support insert 212, prevent the lens from shifting during dispensing, curing and pressing, and ensure the positioning accuracy of the lens.

[0028] The lens middle mold 22 and the lens lower mold 21 are arranged parallel and spaced apart. The lens middle mold 22 is provided with a positioning groove 221 and several clearance grooves 222. The contour of the positioning groove 221 is adapted to the edge shape of the optical lens. After the optical lens is placed, its edge is embedded in the positioning groove 221 to achieve horizontal positioning of the optical lens and further ensure the positioning accuracy of the lens. The clearance grooves 222 are connected to the positioning grooves 221. Their shape is adapted to the protrusions, buckles and other structures of the AR glasses frame. When the frame and the lens are pressed together, the protrusion structure of the frame can be embedded in the clearance grooves 222 to avoid interference between the frame and the lens middle mold 22 and ensure the precise fit between the optical lens and the frame.

[0029] The connecting assembly is disposed between the lens middle mold 22 and the lower template 211 of the lens lower mold 21, realizing an elastic sliding connection between the two. This allows the lens middle mold 22 to smoothly move towards the lens lower mold 21 when compressed, and to automatically reset after the pressure is released. The connecting assembly includes a guide post 213 and an elastic reset member 214. One end of the guide post 213 is fixedly connected to the lower end face of the lens middle mold 22, and the other end slides through the lower template 211 and extends downward through the lower template 211. The end of the guide post 213 away from the lens middle mold 22 is integrally formed with a limiting head. The diameter of the limiting head is larger than the diameter of the rod body of the guide post 213, which is used to limit the sliding of the guide post 213. The movement of the middle mold 22 is designed to prevent excessive movement of the middle mold 22 towards the lower mold 21, which could damage the optical lens. The elastic reset member 214 is sleeved on the rod of the guide post 213, with its two ends abutting against the lower end face of the middle mold 22 and the upper end face of the lower mold 211, respectively. In this embodiment, the elastic reset member 214 is preferably a compression spring. When the middle mold 22 is subjected to downward pressure, the compression spring is compressed synchronously, and the middle mold 22 moves smoothly along the guide post 213 towards the lower mold 21. When the pressure disappears, the reset force of the compression spring pushes the middle mold 22 to move in the opposite direction along the guide post 213 until it returns to the initial parallel interval position, thereby realizing the automatic reset of the middle mold 22.

[0030] The dispensing module 3 is installed on the frame 1 above the lens fixture 2, and is used for high-precision dispensing of the optical lens to a preset dispensing area. It includes a dispensing device, a drive mechanism 32, and a support mechanism. The dispensing device includes a glue cylinder 31 and a dispensing needle. The glue cylinder 31 is a cylindrical body that stores optical adhesive specifically for AR glasses assembly. The dispensing needle is detachably connected to the lower end of the glue cylinder 31, allowing the optical adhesive in the glue cylinder 31 to be evenly extruded through the dispensing needle to complete the dispensing operation. The drive mechanism 32 is signal-connected to the central control module and is controlled by the central control unit. The module control drive includes an X-axis linear slide rail, a Y-axis linear slide rail, and a Z-axis linear slide rail. The three are arranged perpendicularly to each other and are fixedly connected to the frame 1. The X-axis and Y-axis linear slide rails enable the dispensing device to move forward and backward and left and right in the horizontal direction, while the Z-axis linear slide rail enables the dispensing device to move up and down in the vertical direction. The coordinated movement of the three can drive the dispensing device to move precisely to any position in three-dimensional space, so that the dispensing needle can complete the dispensing operation along the preset trajectory of the optical lens. After the dispensing is completed, the drive mechanism 32 can drive the dispensing device to return to the initial position and wait for the next round of operation.

[0031] The support mechanism is disposed between the Z-axis linear slide rail moving end of the drive mechanism 32 and the glue cylinder 31 of the dispensing device. It is used to achieve stable installation and precise radial positioning of the glue cylinder 31, preventing circumferential rotation or radial offset of the glue cylinder 31 during dispensing and ensuring the accuracy of the dispensing trajectory. The support mechanism includes a main support 35, an upper support assembly, a lower support assembly, and a positioning assembly. One end of the main support 35 is fixedly connected to the moving end of the Z-axis linear slide rail and can move synchronously with the drive mechanism 32. The other end of the main support 35 extends vertically. The upper support assembly and the lower support assembly are fixedly fixed to the main support 35 at intervals along the vertical direction, respectively for mounting the upper and lower ends of the glue cylinder 31, forming a two-point support and fixation for the glue cylinder 31. The positioning component is mounted on the upper and lower support components and cooperates with the outer wall of the rubber tube 31 to achieve radial positioning. It includes an upper clamping block 36 and a lower clamping block 37. The upper clamping block 36 is mounted on the upper support component and has an upper positioning hole in its middle. The lower clamping block 37 is mounted on the lower support component and has a lower positioning hole in its middle. The upper and lower positioning holes are arranged coaxially, and their inner walls are in sliding fit with the outer cylindrical surface of the rubber tube 31. The upper and lower ends of the rubber tube 31 are respectively inserted into the upper and lower positioning holes, realizing automatic alignment and precise radial positioning of the rubber tube 31. At the same time, the sliding fit structure facilitates the insertion, removal and disassembly of the rubber tube 31. When the rubber tube 31 needs to be replaced, it can be pulled out directly along the axis of the positioning hole, which is convenient.

[0032] The upper support assembly also includes an upper clamping bracket 33 and an upper fastener. The upper clamping bracket 33 is fixedly connected to the main support 35. The upper clamping block 36 is embedded in the mounting hole of the upper clamping bracket 33, and the upper end of the upper clamping block 36 is provided with an upper boss 361. The upper boss 361 is mounted on the upper end face of the upper clamping bracket 33 to realize the axial positioning of the upper clamping block 36. The upper clamping block 36 is provided with an upper groove 362 that communicates with the upper positioning hole. The upper fastener is threadedly connected to the upper clamping bracket 33. Its end passes through the upper clamping bracket 33 and abuts against the outer wall of the rubber tube 31 through the upper groove 362. Tightening the upper fastener can fix the upper end of the rubber tube 31. The lower support assembly includes a lower clamping bracket 34 and a lower fastener. Its structure is fully compatible with the upper support assembly. The end of the lower fastener passes through the lower clamping bracket 34 and abuts against the outer wall of the glue tube 31 through the lower groove 372 of the lower clamping block 37, thereby fixing the lower end of the glue tube 31. Through the abutting action of the upper and lower fasteners, combined with the radial limiting of the positioning component, the installation of the glue tube 31 is more stable, effectively preventing the glue tube 31 from shifting during the dispensing process.

[0033] The curing module 4 is fixedly connected to the lower template 211 of the lower lens mold 21 and is located on the side of the lower lens mold 21 away from the middle lens mold 22. Its light emission direction is vertically upward towards the support insert 212 of the lower lens mold 21. It is used to pre-cure the optical adhesive after dispensing and to switch to a secondary curing mode during the pressing of the lens and the frame, so as to realize the step-by-step curing and shaping of the optical adhesive. The curing module 4 includes a UV lamp group and a heat dissipation component. The UV lamp group is signal-connected to the central control module, which controls the start, stop and switching of the working mode. The ultraviolet rays emitted by the UV lamp group are penetrable. The translucent support insert 212 evenly illuminates the adhesive application area of ​​the optical lens, providing energy for the curing of the optical adhesive. The heat dissipation component is tightly fitted to the outer wall of the UV lamp assembly. In this embodiment, the heat dissipation component is a structure of heat dissipation fins and a cooling fan. The heat dissipation fins are fitted to the UV lamp assembly to conduct heat, and the cooling fan is set corresponding to the heat dissipation fins to remove the heat generated during the operation of the UV lamp assembly in a timely manner, avoiding the UV lamp assembly from being affected by high temperature aging and affecting its service life. At the same time, it prevents high temperature from being transferred to the optical lens and optical adhesive, which could lead to uneven curing of the optical adhesive and heat deformation of the lens, thus ensuring the stability of the curing operation.

[0034] The pressing module 5 is installed on the frame 1 directly above the lens fixture 2, and is used to press the lens fixture 2 to push the optical lens to precisely fit the AR glasses frame. It includes a sliding guide post 51, a pressure plate 52, and a power drive component. The sliding guide post 51 is vertically oriented, with its lower end fixedly connected to the frame 1 and its upper end extending upwards. The pressure plate 52 is slidably connected to the sliding guide post 51, allowing for smooth vertical lifting and lowering along the sliding guide post 51. The sliding guide post 51 provides guidance for the pressure plate 52, preventing it from tilting during pressing and ensuring uniform transmission of pressing force. The power drive component is a cylinder. The linear drive mechanism 32, including the electric cylinder, is fixedly connected to the frame 1. Its output end is fixedly connected to the upper end face of the pressure plate 52, and the power drive component is signal-connected to the central control module. The central control module controls and drives the pressure plate 52 to press down or reset along the sliding guide post 51. When the pressure plate 52 presses down, it contacts the upper end face of the lens mold 22 and applies downward pressure to push the lens mold 22 closer to the lens lower mold 21, so that the optical lens and the frame fit tightly together. After pressing into place, the pressure plate 52 remains in the pressed state and completes the secondary curing with the curing module 4. After curing is completed, the power drive component drives the pressure plate 52 to reset upward to the initial position.

[0035] The frame 1 is also equipped with an AC fan filter unit 6, which is connected to the central control module and is controlled by the central control module to start and stop. Its air outlet faces the working area of ​​the device, and can continuously deliver clean air to the working area to filter dust, particles and other impurities in the air. This prevents impurities from adhering to the surface of optical lenses or optical adhesives during the dispensing and curing process, ensuring the assembly quality of AR glasses and meeting the clean environment requirements for optical product manufacturing.

[0036] This invention also discloses a dispensing, curing, and bonding method using the aforementioned integrated AR glasses lens dispensing and curing device. This method is executed according to a preset process sequence, with the entire process automatically switched between processes by a central control module. Specifically, it includes the following steps: S1, loading and positioning: The AR glasses optical lens to be assembled is placed on the support insert 212 of the lens fixture 2 by a manual or robotic arm, so that the back of the lens is precisely fitted with the support surface of the support insert 212, and the edge of the lens is embedded in the positioning groove 221 of the lens mold 22, completing the initial positioning of the lens. At this time, the loading position sensor is triggered, and the sensor sends a loading position signal to the central control module. After receiving the signal, the central control module immediately triggers two linkage actions: first, it controls the suction cup 213 on the support insert 212 to start, generating negative pressure to firmly adsorb and fix the optical lens on the support insert 212; second, it controls the AC fan filter unit 6 to start, delivering clean air to the working area of ​​the device. After the suction cup 213 has finished adsorbing and the AC fan filter unit 6 has entered a stable working state, it sends a loading position completion signal back to the central control module.

[0037] S2. Dispensing Operation: After receiving the loading and positioning completion signal, the central control module sends a dispensing start signal to the dispensing module 3 according to the preset process sequence. After receiving the signal, the X-axis, Y-axis, and Z-axis linear slide rails of the drive mechanism 32 move in coordination, driving the dispensing needle of the dispensing device to the dispensing start position of the optical lens. Then, the drive mechanism 32 drives the dispensing device to move along the preset dispensing trajectory of the optical lens. The optical adhesive in the glue cylinder 31 is evenly squeezed out through the dispensing needle, completing the dispensing operation on the preset dispensing area of ​​the optical lens. During the dispensing process, the positioning component of the bracket mechanism radially limits the glue cylinder 31, effectively preventing the glue cylinder 31 from shifting and causing deviation of the dispensing trajectory.

[0038] S3, Pre-curing: After the dispensing module 3 completes the dispensing operation along the preset trajectory, the dispensing completion status sensor sends a dispensing completion signal to the central control module. Upon receiving this signal, the central control module simultaneously triggers two linked actions: First, it sends a pre-curing start signal to the curing module 4, controlling the UV lamp group of the curing module 4 to start, emitting ultraviolet rays that penetrate the support insert 212 and irradiate the dispensing area of ​​the optical lens, performing a pre-curing operation on the dynamic optical adhesive, so that the optical adhesive is initially shaped, avoiding adhesive overflow during subsequent pressing. Second, it sends a reset signal to the dispensing module 3, controlling the drive mechanism 32 to drive the dispenser to reset to the initial position, waiting for the next round of dispensing operation. After resetting, the dispensing module 3 sends a reset completion signal back to the central control module.

[0039] S4. Frame Positioning: The curing module 4 maintains the pre-curing operation state. The manual or robotic arm places the AR glasses frame on top of the pre-cured optical lens, so that the part of the frame to be bonded is precisely aligned with the glued area of ​​the optical lens. At the same time, the protrusions, buckles and other structures of the frame are embedded into the clearance groove 222 of the lens mold 22 to avoid interference during pressing. After the frame positioning is completed, the frame positioning status sensor is triggered, and the sensor sends the frame positioning signal to the central control module.

[0040] S5, Pressing Trigger: After receiving the frame positioning signal, the central control module sends a pressing start signal to the pressing module 5 according to the process sequence. After receiving the signal, the pressing module 5 starts the power drive, which drives the pressure plate 52 to move vertically downward along the sliding guide post 51. After the pressure plate 52 contacts the upper end surface of the lens middle mold 22, it continues to apply downward pressure, pushing the lens middle mold 22 to smoothly approach the lens lower mold 21 along the guide post 213. The compression spring is compressed synchronously, and the lens middle mold 22 drives the optical lens to gradually move towards the AR glasses frame, so that the two slowly fit together.

[0041] S6. Synchronous Secondary Curing: The pressure plate 52 is pressed down to the preset position by the power drive component, and the optical lens and AR glasses frame are fully bonded. At this time, the pressing position sensor sends a pressing position signal to the central control module. After receiving the signal, the central control module immediately sends a secondary curing switching signal to the curing module 4, controlling the UV lamp group of the curing module 4 to switch to the secondary curing working mode to perform secondary curing of the optical adhesive. During this process, the pressing module 5 maintains the pressing state to achieve bonding and pressure maintenance between the optical lens and the frame, ensuring full adhesion between the adhesive layer and the frame and lens, and effectively avoiding problems such as delamination and warping.

[0042] S7. Reset and Unloading: After the curing module 4 completes the secondary curing operation, the curing completion status sensor sends a curing completion signal to the central control module. After receiving the signal, the central control module triggers the linkage reset action in sequence. First, it sends a reset signal to the pressing module 5, controlling the power drive component to drive the pressure plate 52 to reset upward along the sliding guide post 51 to the initial position. After the pressure plate 52 is reset in place, it sends a pressing reset signal back to the central control module. After receiving the signal, the central control module sends a release signal to the lens fixture 2, controlling the suction cup 213 to release the negative pressure and release the adsorption on the optical lens. At this time, under the reset force of the compression spring, the lens middle mold 22 moves upward along the guide post 213 to return to the initial position parallel to the lens lower mold 21. Finally, the assembled AR glasses are taken out manually or by a robot, and the device returns to the initial standby state, waiting for the next loading signal to start a new round of operation.
