[0024] Among them, double mounting stations (a first mounting station and a second mounting station) are adopted. After the first mounting station completes the mounting of the first piece (such as 0°), the optical device body with the first filter mounted thereon is cured by the curing mechanism 11 to prevent the first filter in the optical device body from falling off. An angle flipping mechanism 16 is arranged after the first mounting station. The angle is adjusted by the angle flipping mechanism 16, and the second mounting station completes the mounting of the second piece (such as 45°) to ensure that the second filter can be fitted at a precise angle to achieve continuous mounting of multiple filters. A manipulator 5 and a conveying mechanism are adopted to realize automatic transfer of the optical device body to reduce manual intervention. Each mounting station is equipped with a visual inspection mechanism to detect the uniformity of colloid coating, the position deviation of the filter, etc. The sorting mechanism automatically removes unqualified products to ensure that only qualified parts enter the next station to improve the overall yield. That is, the whole process of loading → dispensing → mounting → curing → inspection → sorting → flipping → secondary mounting is fully automated to reduce manual intervention and improve production capacity.

[0025] In this embodiment, if Figures 1 to 4 As shown, the loading mechanism includes a body placement tray 4 and a flexible vibration tray 3; the body placement tray 4 is used to stack and place the optical device body parts; the flexible vibration tray 3 is arranged at the discharge port of the body placement tray 4 and is arranged close to the manipulator 5; the flexible vibration tray 3 is used to transfer the optical device body parts. Among them, the body placement tray 4 is used to stack and store unprocessed optical device body parts, and the optical device body of the body placement tray 4 is vibrated down and placed on the flexible vibration tray 3 through the orderly frequency vibration of the flexible vibration tray 3; during the vibration process, the optical device body parts automatically adjust their posture due to the difference in shape and center of gravity, and finally move to the discharge port to be grasped in a unified direction. Preferably, the flexible vibration tray 3 makes the disordered optical device body parts orderly arranged along the preset track in the tray through the slight vibration of a specific frequency, ensuring that the optical device body parts of different sizes can all move smoothly to the discharge port; the camera scans the discharge port of the flexible vibration tray 3 in real time to detect the center coordinates, angle offset and surface defects of the optical device body parts; if a component with an incorrect posture is detected, the vibration tray is triggered to adjust twice until it meets the grasping conditions. When the optical device body reaches the target position and the posture is qualified, the visual system sends the command of the grabbing coordinates (X / Y / Z) and the rotation angle to the manipulator 5; the manipulator 5 quickly moves to the top of the optical device body according to the coordinates provided by the visual system; if there is an angle deviation of the optical device body, the end fixture of the manipulator 5 automatically rotates to compensate for the angle to ensure vertical grabbing; the gripper 6 of the manipulator 5 grabs with a force that adapts to the shape of the optical device body to avoid damage. After the gripper 6 grabs the optical device body, the manipulator 5 transfers the optical device body along the preset path to the conveying mechanism to enter the first mounting station of the next process.

[0026] In this embodiment, if Figures 1 to 4As shown, the conveying mechanism includes a screw module 7 and a movable positioning plate 8; the movable positioning plate 8 is slidably connected to the screw module 7, and the movable positioning plate 8 is used to carry and fix the optical device body; the screw module 7 extends along the conveying direction of the optical device body; the input end of the screw module 7 is arranged close to the clamping area of ​​the manipulator 5, and the output end of the screw module 7 is close to the patch station of the patch mechanism 10; the glue dispensing station of the glue dispensing mechanism 9 is arranged on one side of the screw module 7 and is arranged corresponding to the screw module 7; wherein, the screw module 7 drives the movable positioning plate 8 to intermittently move along the screw module 7, so that the optical device body passes through the glue dispensing station and the patch station in sequence. Among them, the manipulator 5 places the optical device body part to the input end position on the mobile positioning plate 8, and the screw module 7 moves in steps according to the preset program, and pauses after moving a station distance, corresponding to the dispensing station and the patch station respectively, to ensure the accuracy of repeated positioning of the optical device body part at the dispensing station and the patch station; preferably, the mobile positioning plate 8 fixes the optical device body part through a negative pressure suction hole or a micro-clamp to prevent displacement during transportation. Specifically: the manipulator 5 places the optical device body part on the mobile positioning plate 8, and the screw module 7 is started. When the mobile positioning plate 8 carries the optical device body part to the dispensing station, the screw module 7 is paused at this time, and the dispensing head of the dispensing mechanism 9 quantitatively applies glue on the optical device body part according to the preset path (such as a ring or dot matrix); preferably, after dispensing, the height of the colloid is detected by a laser sensor to ensure the uniformity of the glue amount. Afterwards, the mobile positioning plate 8 continues to slide on the screw module 7, so that the mobile positioning plate 8 moves to the patch station with the glued optical device body. At this time, the screw module 7 is paused, and the filter extractor 15 of the patch mechanism 10 picks up the filter from the filter placement plate. Based on the secondary positioning of the visual system, the filter extractor 15 accurately fits the filter to the surface of the colloid; during patching, the filter extractor 15 applies constant pressure to ensure that the colloid is evenly diffused and free of bubbles; preferably, if the optical device body rotates slightly during the conveying process, the rotating suction nozzle of the patch mechanism 10 can automatically adjust the angle of the filter. That is, the conveying mechanism connects the glue dispensing and patching processes in series through the precise intermittent drive of the screw module 7 and the stable load of the mobile positioning plate 8, solving the problems of low positioning accuracy and insufficient flexibility of the traditional conveyor belt, and is particularly suitable for the automated assembly of high-precision optical devices that require multi-station collaboration.

[0027] In this embodiment, if Figures 1 to 4As shown, the glue dispensing mechanism 9 includes a glue storage tank, a glue dispensing head and a pressure sensor; the glue storage tank is used to store the glue; the glue dispensing head is connected to the glue storage tank and is arranged corresponding to the optical device body on the mobile positioning plate 8; the first sensor is arranged on the glue dispensing head; the first sensor is used to monitor whether the optical device body is in place. Among them, the glue storage tank is used for glue storage and supply, and the glue output to the glue dispensing head is controlled by air pressure or a screw pump to ensure a stable amount of glue. Preferably, the glue storage tank is equipped with a temperature control module to prevent changes in glue viscosity from affecting the glue dispensing accuracy. The first sensor is used to detect whether the optical device body is in place. Preferably, the first sensor uses a photoelectric sensor or an optical fiber probe to detect whether the optical device body on the mobile positioning plate 8 has reached the glue dispensing station; if it is detected that the workpiece is in place, a signal is sent to the control system to start the glue dispensing head operation; if the workpiece is not detected, the glue dispensing is suspended and an alarm is issued to avoid glue waste or equipment pollution.

[0028] Specific process: the conveying mechanism delivers the optical device body to the dispensing station, and the first sensor detects that the workpiece is in place; the control system receives the signal and triggers the dispensing head to descend to a preset height, such as 1mm from the workpiece surface; the glue storage tank supplies glue to the dispensing head, and the dispensing head applies glue according to the programmed path. When the dispensing is completed, the dispensing head is reset and the conveying mechanism moves to the next station. In other words, the closed-loop control with stable glue supply from the glue storage tank, precise triggering of the sensor, and high-precision execution of the dispensing head solves the problems of glue waste and position offset in the traditional dispensing process, which is particularly suitable for the automated production of optical devices that are sensitive to glue dosage and position.

[0029] In this embodiment, if Figures 1 to 4As shown, the patch mechanism 10 includes a filter placement plate, a horizontal linear module and a filter extractor 15; the filter placement plate is used to carry the filter to be mounted; preferably, the filter placement plate fixes the filter by a precision fixture or a vacuum adsorption hole to ensure that each filter is in a preset pickup position; preferably, the surface of the filter placement plate is covered with an anti-static film to prevent the filter from absorbing dust or scratches during transportation; the horizontal linear module is arranged on one side of the filter placement plate and is arranged close to the output end of the screw module 7; preferably, the horizontal linear module adopts a ball screw or a linear motor module driven by a servo motor to drive the filter extractor 15 to move linearly; the filter extractor 15 is slidably connected to the horizontal linear module; preferably, the Z-axis drive unit is controlled by a stepper motor or a servo electric cylinder. The vertical displacement of the vacuum nozzle assembly and the downward pressing speed are adjustable to avoid impact damage to the filter; the filter extractor 15 includes a vacuum nozzle assembly and a Z-axis drive unit; the vacuum nozzle assembly is used to pick up the filter on the filter placement plate; the Z-axis drive unit is connected to the vacuum nozzle assembly and is arranged on the horizontal linear module; the Z-axis drive unit is used to drive the vertical displacement of the vacuum nozzle assembly; wherein, the vacuum nozzle assembly moves to the top of the filter placement plate through the horizontal linear module, and the Z-axis drive unit drives the vacuum nozzle assembly to descend and pick up the filter; the horizontal linear module moves the filter to the top of the optical device body on the mobile positioning plate 8, and mounts the filter to the optical device body that has been glued. Preferably, the patch mechanism 10 is also provided with a second sensor, and optionally, the second sensor adopts a photoelectric sensor or an optical fiber probe to detect whether the optical device body on the mobile positioning plate 8 has reached the glue dispensing station.

[0030] In this embodiment, if Figures 1 to 4As shown, the patch mechanism 10 (filter placement plate, horizontal linear module, filter extractor 15) and the conveying mechanism (screw module 7 + movable positioning plate 8) work together to achieve accurate picking, positioning transfer and automatic mounting of filters, specifically: when the second sensor detects that the optical device body is in place, the horizontal linear module moves the vacuum nozzle to above the filter placement plate, the Z-axis drive unit drives the vacuum nozzle assembly to descend, the vacuum nozzle assembly adsorbs the filter, and the Z-axis drive unit drives the vacuum nozzle assembly to lift again; the horizontal linear module moves laterally along the patch station close to the patch station to convey the filter to the top of the optical device body on the movable positioning plate 8; then the Z-axis drive unit drives the vacuum nozzle assembly to slowly descend, the vacuum nozzle assembly adheres the filter to the optical device body that has been glued, the vacuum nozzle assembly releases the filter, and then the vacuum nozzle assembly is reset by the Z-axis drive unit; the horizontal linear module returns to the filter placement plate position to prepare for the next pick-up. That is, the patch mechanism 10 realizes the fully automated operation of the filter from feeding to mounting through the precise positioning of the horizontal linear module, the flexible control of the Z axis and the reliable picking up of the vacuum nozzle assembly, solving the problems of low efficiency and poor consistency of manual patch mounting, and is particularly suitable for the assembly of high-precision optical devices that are sensitive to position and force.

[0031] In this embodiment, the visual inspection mechanism includes a frame, an optical magnifying component 13 and an industrial camera 12; the frame is arranged in the accommodating cavity, and the frame plays a role of stable support and positioning; preferably, the height and angle of the frame can be fine-tuned to ensure that the optical magnifying component 13 and the detection surface of the optical device body maintain an optimal working distance; the optical magnifying component 13 is arranged on the frame and corresponds to the optical device body output by the curing mechanism 11; the optical magnifying component 13 ensures the true restoration of the filter edge and the colloid morphology; optionally, a ring light source or a coaxial light source is also provided to optimize the lighting according to the refractive characteristics of the transparent filter and the glue; the industrial camera 12 is arranged on the frame and coaxially arranged with the optical magnifying component 13; the industrial camera 12 is used to collect the amplified filter image; the industrial camera 12 is mainly used for image acquisition and analysis; preferably, the industrial camera 12 adopts a global shutter CMOS camera to avoid motion blur.

[0032] In this embodiment, if Figures 1 to 4As shown, the visual inspection mechanism (frame, optical magnification component 13, industrial camera 12) realizes the automatic detection of the position accuracy, colloid state and defects of the mounted filter through high-precision optical imaging and image analysis technology. Specifically: after the optical device body with the first filter mounted is solidified, before being transported to the angle flip mechanism 16, it will first be moved to the visual inspection station, the optical magnification component 13 focuses on the filter mounting area on the optical device body, and the industrial camera 12 is started, and the image is captured and analyzed to analyze the colloid area, thickness and defects of the filter on the optical device body; it can be understood that the industrial camera 12 can perform multi-parameter synchronous detection, and a single shot can simultaneously complete the determination of the filter position, colloid state, and surface defects (scratches, contamination); when the optical device body is detected as a qualified part, it is transported to the next process; when the optical device body is detected as an unqualified part, it is marked and removed by the sorting mechanism.

[0033] That is, the visual inspection mechanism forms a closed-loop quality monitoring system through the high-definition imaging of the optical amplification component 13 and the intelligent analysis of the industrial camera 12, which solves the problems of low efficiency and strong subjectivity of manual inspection. It is particularly suitable for the production of optical devices with strict requirements on mounting accuracy and glue quality, ensuring that the mounting status of each filter meets the design standards.

[0034] In this embodiment, the sorting mechanism includes a push rod assembly 14, a driving member and a recovery box; the push rod assembly 14 is arranged along a conveying direction perpendicular to the optical device body, and moves along the conveying direction perpendicular to the conveying direction to push NG parts out of the sorting station laterally onto the conveying track, while qualified parts continue to move forward; and is arranged close to the visual inspection mechanism; the push rod assembly 14 is used to sort the optical device body; it should be clear that the conveying mechanism of the curing mechanism 11 conveys the optical device body to the sorting station, ensuring that the movement of the push rod assembly 14 is strictly aligned with the position of the optical device body; the push rod assembly 14 The end is made of flexible material, such as silicone, to avoid impact and damage to the workpiece; optionally, the push rod assembly 14 is provided with a lifting module to adapt to optical device body parts of different thicknesses; a driving member is connected to the push rod assembly 14; the driving member is used to drive the push rod assembly 14 to perform sorting actions; preferably, the driving member adopts a cylinder (pneumatic drive) or a linear motor (electric) to meet the sorting requirements; a recycling box is set on the side away from the push rod assembly 14; the recycling box is used to collect unqualified optical device body parts; preferably, the inner wall of the recycling box is attached with cushioning material to avoid secondary contamination caused by the bouncing of NG parts.

[0035] In this embodiment, if Figures 1 to 4As shown, the sorting mechanism (push rod assembly 14, drive member, recycling box) works in conjunction with the visual inspection mechanism to achieve automated sorting and rejection of defective parts of the optical device body, ensuring that only qualified products flow into the next process. Specifically: After the visual inspection mechanism completes the quality judgment of the optical device body, it transmits the signal to the control system of the sorting mechanism, marking the workpiece as qualified (PASS) or unqualified (NG). If it is an NG part, the conveying mechanism of the curing mechanism 11 is suspended, and the drive member pushes the push rod assembly 14 to move horizontally, pushes the NG part into the recycling box, and the push rod is reset; if it is a PASS part, the conveying mechanism of the curing mechanism 11 continues to operate, and the qualified part flows into the next station, that is, enters the angle flipping mechanism 16; that is, the sorting mechanism forms an efficient closed-loop quality control through the precise triggering of visual discrimination, the rapid response of the push rod assembly 14 and the orderly collection of the recycling box, which solves the problems of low efficiency and high missed detection rate of traditional manual sorting, and is particularly suitable for automated production lines with high precision requirements such as optical devices, ensuring that defective products are 100% rejected and qualified products pass without damage.

[0036] In this embodiment, the angle flip mechanism 16 includes a rotating platform, a motor, an angle encoder and a proximity sensor; the rotating platform is arranged at the output end of the curing mechanism 11; the rotating platform is used to place the optical device body that has been mounted and cured at the first mounting station; preferably, the rotating platform uses vacuum adsorption or mechanical clamps to fix the optical device body to prevent slippage during rotation; the motor is arranged on the rotating platform; preferably, the motor drives the rotating platform through a reducer or direct drive, and the torque is stable and there is no jitter; the motor drives the rotating platform to rotate; the angle encoder is coaxially connected to the motor; the angle encoder is used to detect the rotation angle of the rotating platform; preferably, the angle encoder uses an absolute An encoder is used to directly measure the angular position of the rotating platform, transmit the angle data to the control system, compare it with the preset target angle (such as 45°), and dynamically correct the motor rotation; a proximity sensor is arranged on the rotating platform, and preferably, the proximity sensor adopts an inductive or photoelectric proximity sensor to detect whether there is an optical device body in place on the rotating platform; when the proximity sensor senses that the optical device body with a 0° patch is transported to the specified position, the optical device body will be accurately adjusted within the range of 0° to 45°, meeting the mounting requirements of the 45° filter; if the optical device body is detected, a signal is sent to the control system to allow the motor to start rotating; if the optical device body is not detected, the flipping process is suspended and an alarm is issued to avoid idling losses.

[0037] In this embodiment, if Figures 1 to 4As shown, the angle flipping mechanism 16 (rotating platform, motor, angle encoder, proximity sensor) realizes precise angle flipping (such as rotating from 0° to 45°) of the optical device body after the first filter is mounted through precise coordinated control to meet the mounting requirements of the combined filter. Specifically: the first mounting station mounts the 0° filter to the optical device body and completes the curing. The optical device body is transported from the curing mechanism 11 to the rotating platform. The proximity sensor detects a signal and triggers the control system to prepare for flipping; the motor starts to drive the rotating platform to rotate, and the angle encoder feeds back the angle in real time. When the preset angle (such as 45°) is reached, the motor stops. After the flipping is completed, the rotating platform locks the angle, and the conveying mechanism of the second mounting station transfers the optical device body to the second mounting station for dispensing and mounting of the 45° filter, and then the rotating platform is reset to the initial position. That is, the angle flipping mechanism 16 solves the core problem of multi-angle combination filter mounting through sensor triggering, motor drive, and precise control of encoder closed-loop feedback. It is particularly suitable for optical communication devices that require combined filters superimposed at specific angles such as 0° and 45°, and realizes highly repeatable and highly reliable automated production.

[0038] In this embodiment, if Figure 5 As shown, the housing 17 is also provided with a plurality of air outlets, and the air outlets are connected to the accommodating cavity; each of the air outlets is provided with a fan 19 to form a local airflow circulation, such as preferentially covering the heat-generating areas such as the dispensing mechanism 9 and the curing mechanism 11, to avoid local overheating and play a role in heat dissipation; it should be noted that there is a fan 19 on the housing 17 corresponding to the rotating platform to cool the optical device body that has completed the 0° patch and then perform the dispensing before the 45° patch to ensure that the dispensing is not solidified. In addition, the fan 19 exhausts air outward, so that the accommodating cavity forms a slight negative pressure to prevent external dust from intruding. That is, the heat dissipation system solves the pain points of precision optical equipment being sensitive to temperature and having low dust tolerance through the collaborative design of distributed fans 19 + intelligent temperature control, which not only ensures the process stability of filter placement, but also extends the service life of the equipment. It is the key support for the high-reliability operation of automated placement equipment.

[0039] What you need to know is that Figure 5 As shown, the main functions of the shell 17 are, first, to prevent dust from entering during the patch process, and second, to prevent problems caused by human touch during the operation of the machine; a warning light 18 is also arranged on the top of the shell 17, and once a problem occurs during operation, a warning light will sound until the problem is solved; in addition, a problem handling button is arranged on the front of the shell 17; it should be noted that the accommodating cavity of the shell 17 is divided into a first accommodating cavity and a second accommodating cavity by the bottom plate 20, and the first accommodating cavity is mainly used to realize the setting up of the entire design scheme, while the second accommodating cavity is used to organize and collect the routes used to prevent the lines from being messy.

[0040] In this embodiment, if Figure 1 and Figure 2 As shown, it also includes a fill light component, which is arranged in the accommodating cavity; the fill light component includes a fixed frame 1, a camera and a fill light screen 2; the fill light screen 2 is movably connected to the fixed frame 1 and is arranged corresponding to the feeding mechanism; preferably, the fill light screen 2 adopts an LED array or a light guide plate to emit diffuse light to eliminate reflections or shadows on the surface of the optical device body; preferably, the fill light screen 2 is connected to the fixed frame 1 through a slide rail or a hinge, and the angle of the fill light screen 2 can be adjusted; the fill light screen 2 is provided with a positioning hole; the camera is penetrated through the positioning hole and connected to the fixed frame 1; the camera passes through the positioning hole and is coaxial with the positioning hole, and aligns with the optical device body on the flexible vibration plate 3 to avoid the fill light screen 2 blocking the imaging field of view, thereby ensuring that the intelligent recognition camera can have a sufficiently bright light source in a closed space.

[0041] In this embodiment, if Figure 1 and Figure 2 As shown, the fill light assembly (fixed frame 1, fill light screen 2, camera) works in coordination with the feeding mechanism, and solves the low contrast recognition problem of the optical device body during the feeding process through dynamic fill light and visual positioning technology, ensuring the accuracy and reliability of the robot 5's grasping. Specifically, the optical device body enters the feeding station of the flexible vibration plate 3 from the body placement plate 4, and the flexible vibration plate 3 stops vibrating; at this time, the brightness of the fill light screen 2 is automatically adjusted according to the material of the workpiece, and the camera shoots the optical device body through the positioning hole, and extracts the center coordinates and rotation angle of the optical device body; the data is transmitted to the robot 5, and the position and posture of the clamp 6 are corrected; after the robot 5 completes the grasping, the brightness of the fill light screen 2 is reduced to the standby mode. That is, the fill light assembly overcomes the recognition problem caused by the variety of materials when optical devices are fed, significantly improves the grasping success rate of the robot 5, and is a key module to ensure the high-precision and high-robustness operation of automated placement equipment through the closed-loop cooperation of dynamic adjustable lighting and coaxial visual positioning.
