[0063] As Figures 1 to 5As shown in the figure, the present application provides an automatic patch device for a combined filter, including a housing 17, a feeding mechanism, a manipulator 5, a conveying mechanism, a dispensing mechanism 9, a patching mechanism 10, a curing mechanism 11, a vision inspection mechanism, a sorting mechanism, and an angle flipping mechanism 16; the housing 17 has a receiving cavity; the feeding mechanism is arranged in the receiving cavity; the feeding mechanism is used for placing the optical device body; the manipulator 5 is arranged in the receiving cavity and is close to the discharge port of the feeding mechanism; the manipulator 5 is provided with a gripper 6, and the gripper 6 is used for gripping and transferring the optical device body; preferably, the manipulator 5 is a four-axis manipulator 5, which can cooperate with the X-axis, Y-axis, Z-axis, and rotation axis, enabling the manipulator 5 to perform linear movement and rotation in three-dimensional space, with the ability to move freely in multiple angles, flexibly adjust the position and direction, so as to accurately grip and transfer the optical device body; the conveying mechanism is arranged in the receiving cavity and is close to the manipulator 5; the conveying mechanism is used for receiving and conveying the optical device body; the mounting station device is arranged in the receiving cavity and is located at the output end of the conveying mechanism; the mounting station device includes a first mounting station and a second mounting station arranged adjacent to each other along the processing path; each mounting station includes: the dispensing mechanism 9 is located on one side of the conveying mechanism; the dispensing mechanism 9 is used for applying glue to the optical device body; the patching mechanism 10 is located at the discharge end of the conveying mechanism; the patching mechanism 10 is used for patching the filter onto the optical device body that has been dispensed with glue; the curing mechanism 11 is located at the output end of the patching mechanism 10; the curing mechanism 11 is used for curing the optical device body with the filter patched; preferably, the curing mechanism 11 is a filter baking table; the vision inspection mechanism is located on one side of the curing mechanism 11 and corresponds to the patching mechanism 10; the vision inspection mechanism is used for detecting the patching position of the filter on the optical device body and the state of the glue; the sorting mechanism is located on one side of the curing mechanism 11 and corresponds to the vision inspection mechanism; the sorting mechanism is used for sorting the qualified optical device bodies and the unqualified optical device bodies; the first mounting station further includes an angle flipping mechanism 16, and the angle flipping mechanism 16 is arranged at the output end of the curing mechanism 11 of the first mounting station and is located at the input end of the second mounting station; the angle adjustment mechanism is used for rotating the optical device body that has completed patching through the first mounting station to a set angle.

[0064] Among them, a double-mounting station (the first mounting station and the second mounting station) is 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 passes through the curing mechanism 11 for curing the filter, preventing the first filter in the optical device body from falling off; an angle flipping mechanism 16 is arranged after the first mounting station, and the angle is adjusted through the angle flipping mechanism 16. The second mounting station completes the mounting of the second piece (such as 45°), ensuring that the second filter can be attached at an accurate angle to achieve continuous mounting of multiple filters; a manipulator 5 and a conveying mechanism are used to realize automatic transfer of the optical device body, reducing manual intervention; each mounting station is equipped with a vision detection mechanism to detect the uniformity of colloid coating, the position deviation of the filter, etc.; the sorting mechanism automatically rejects unqualified products to ensure that only qualified parts enter the next station, improving the overall yield; that is, making the process of feeding → dispensing → chip mounting → curing → detection → sorting → flipping → secondary chip mounting fully automated, reducing manual intervention and increasing production capacity.

[0065] In this embodiment, as Figures 1 to 4 shown, the feeding mechanism includes an optical device body placement tray 4 and a flexible vibrating tray 3; the optical device body placement tray 4 is used for stacking and placing the optical device bodies; the flexible vibrating tray 3 is arranged at the discharge port of the optical device body placement tray 4 and is close to the manipulator 5; the flexible vibrating tray 3 is used for transferring the optical device bodies. Among them, the optical device body placement tray 4 is used for stacking and storing unprocessed optical device bodies, and the optical device bodies on the optical device body placement tray 4 are vibrated and placed down to the flexible vibrating tray 3 through the orderly frequency vibration of the flexible vibrating tray 3; during the vibration process, the optical device bodies automatically adjust their postures due to differences in shape and center of gravity, and finally move to the waiting-to-be-grabbed position at the discharge port in a unified direction. Preferably, the flexible vibrating tray 3 makes the messy optical device bodies arranged orderly along a preset track in the tray through micro-amplitude vibration at a specific frequency, ensuring that optical device bodies of different sizes can smoothly move to the discharge port; a camera scans the discharge port of the flexible vibrating tray 3 in real time to detect the center coordinates, angle offset and surface defects of the optical device bodies; if a component with an incorrect posture is detected, the vibrating tray is triggered for secondary adjustment until the grabbing condition is met. When the optical device body reaches the target position and has a qualified posture, the vision system sends instructions of the grabbing coordinates (X / Y / Z) and rotation angle to the manipulator 5; the manipulator 5 quickly moves directly above the optical device body according to the coordinates provided by the vision system; if there is an angle deviation in the optical device body, the clamp at the end 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 adapted 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 a preset path to the conveying mechanism to enter the first mounting station of the next process.

[0066] In this embodiment, as Figures 1 to 4As shown, the conveying mechanism includes a lead screw module 7 and a moving positioning disk 8; the moving positioning disk 8 is slidably connected to the lead screw module 7, and the moving positioning disk 8 is used to carry and fix the laser device body; the lead screw module 7 extends along the conveying direction of the laser device body; the input end of the lead screw module 7 is arranged near the clamping area of the manipulator 5, and the output end of the lead screw module 7 is near the patching station of the patching mechanism 10; the dispensing station of the dispensing mechanism 9 is arranged on one side of the lead screw module 7 and corresponds to the lead screw module 7; wherein, the lead screw module 7 drives the moving positioning disk 8 to intermittently move along the lead screw module 7, so that the laser device body sequentially passes through the dispensing station and the patching station. Among them, the manipulator 5 places the laser device body at the input end position on the moving positioning disk 8, and the lead screw module 7 moves step by step according to a preset program and pauses after moving a distance of each station, corresponding to the dispensing station and the patching station respectively, to ensure the repeated positioning accuracy of the laser device body at the dispensing station and the patching station; preferably, the moving positioning disk 8 fixes the laser device body through negative pressure suction holes or micro jigs to prevent displacement during transportation. Specifically: the manipulator 5 places the laser device body on the moving positioning disk 8, and the lead screw module 7 starts. When the moving positioning disk 8 carries the laser device body to move to the dispensing station, the lead screw module 7 pauses at this time, and the dispensing head of the dispensing mechanism 9 quantitatively applies glue on the laser device body according to a preset path (such as a ring or a dot matrix); preferably, after dispensing, the height of the glue is detected by a laser sensor to ensure the uniformity of the glue amount. Then, the moving positioning disk 8 continues to slide on the lead screw module 7, so that the moving positioning disk 8 carries the laser device body with glue applied to move to the patching station. At this time, the lead screw module 7 pauses, and the filter extraction device 15 of the patching mechanism 10 picks up the filter from the filter placement disk, and based on the secondary positioning of the vision system, the filter extraction device 15 accurately fits the filter onto the glue surface; a constant pressure is applied by the filter extraction device 15 during patching to ensure uniform diffusion of the glue and no air bubbles; preferably, if the laser device body rotates slightly during transportation, the rotating suction nozzle of the patching mechanism 10 can automatically adjust the angle of the filter. That is, through the precise intermittent drive of the lead screw module 7 and the stable bearing of the moving positioning disk 8, this conveying mechanism connects the dispensing and patching processes in series, solving the problems of low positioning accuracy and insufficient flexibility of the traditional conveyor belt, and is especially suitable for the automated assembly of high-precision optical devices that require multi-station cooperation.

[0067] In this embodiment, as Figures 1 to 4As shown, the dispensing mechanism 9 includes a glue storage tank, a dispensing head, and a pressure sensor; the glue storage tank is used to store the glue; the dispensing head is connected to the glue storage tank and is arranged corresponding to the optical device body on the moving positioning disk 8; a first sensor is arranged on the 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 dispensing head is controlled by air pressure or a screw pump to ensure stable glue volume. Preferably, the glue storage tank is equipped with a temperature control module to prevent the change of glue viscosity from affecting the 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 moving positioning disk 8 reaches the dispensing station; if the workpiece is detected to be in place, a signal is sent to the control system to start the operation of the dispensing head; if the workpiece is not detected, the dispensing is paused and an alarm is given to avoid glue waste or equipment pollution.

[0068] Specific process: The conveying mechanism sends 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 1 mm from the surface of the workpiece; 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 returns to its original position, and the conveying mechanism moves to the next station; that is, through the stable glue supply of the glue storage tank, the precise triggering of the sensor, and the high-precision execution of the dispensing head in a closed-loop control, the problems of glue waste and position deviation in the traditional dispensing process are solved, which is especially suitable for the automated production of optical devices that are sensitive to glue consumption and position.

[0069] In this embodiment, as Figures 1 to 4As shown, the patch mechanism 10 includes a filter placement disc, a horizontal linear module, and a filter extractor 15; the filter placement disc is used to carry the filter to be mounted; preferably, the filter placement disc fixes the filter through a precision jig or a vacuum suction hole to ensure that each filter is in a preset picking position; preferably, the surface of the filter placement disc is covered with an anti-static film to prevent the filter from adsorbing dust or being scratched during handling; the horizontal linear module is arranged on one side of the filter placement disc and is close to the output end of the lead screw module 7; preferably, the horizontal linear module uses 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 controls the vertical displacement of the vacuum suction nozzle assembly through a stepping motor or a servo cylinder, and the downward pressure speed is adjustable to avoid impact damage to the filter; the filter extractor 15 includes a vacuum suction nozzle assembly and a Z-axis drive unit; the vacuum suction nozzle assembly is used to pick up the filter on the filter placement disc; the Z-axis drive unit is connected to the vacuum suction 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 suction nozzle assembly; wherein, the vacuum suction nozzle assembly moves above the filter placement disc through the horizontal linear module, and the Z-axis drive unit drives the vacuum suction nozzle assembly to descend and pick up the filter; the horizontal linear module moves the filter above the optical device body part on the moving positioning disc 8 and mounts the filter on the optical device body part that has been dispensed with glue. Preferably, the patch mechanism 10 is also provided with a second sensor. Optionally, the second sensor uses a photoelectric sensor or an optical fiber probe to detect whether the optical device body part on the moving positioning disc 8 reaches the dispensing station.

[0070] In this embodiment, as Figures 1 to 4As shown, the chip mounting mechanism 10 (filter placement tray, horizontal linear module, filter extractor 15) and the conveying mechanism (lead screw module 7 + moving positioning plate 8) work together to achieve precise picking, positioning transfer, and automated mounting of the filter. Specifically: when the second sensor detects that the optical device body part has arrived, the horizontal linear module moves the vacuum suction nozzle above the filter placement tray, and the Z-axis drive unit drives the vacuum suction nozzle assembly to descend. The vacuum suction nozzle assembly adsorbs the filter, and the Z-axis drive unit drives the vacuum suction nozzle assembly to rise again; the horizontal linear module moves horizontally towards the chip mounting station, transporting the filter to directly above the optical device body part on the moving positioning plate 8; then the Z-axis drive unit drives the vacuum suction nozzle assembly to slowly descend, and the vacuum suction nozzle assembly fits the filter onto the optical device body part that has been dispensed with glue. The vacuum suction nozzle assembly releases the filter, and then the Z-axis drive unit resets the vacuum suction nozzle assembly; the horizontal linear module returns to the position of the filter placement tray to prepare for the next pick. That is, the chip mounting mechanism 10 realizes the full-automatic 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 of the vacuum suction nozzle assembly, solving the problems of low efficiency and poor consistency in manual chip mounting, and is especially suitable for the assembly of high-precision optical devices that are sensitive to position and force.

[0071] In this embodiment, the vision inspection mechanism includes a frame, an optical magnification component 13, and an industrial camera 12; the frame is disposed in the accommodation cavity, and the frame plays a role in stable support and positioning; preferably, the height and angle of the frame can be finely adjusted to ensure that the optical magnification component 13 maintains the best working distance from the inspection surface of the optical device body part; the optical magnification component 13 is disposed on the frame and is provided corresponding to the optical device body part output by the curing mechanism 11; the optical magnification component 13 ensures the true restoration of the edge of the filter and the shape of the glue; optionally, a ring light source or a coaxial light source is also provided to optimize the illumination according to the refraction characteristics of the transparent filter and the glue; the industrial camera 12 is disposed on the frame and is coaxially arranged with the optical magnification component 13; the industrial camera 12 is used to collect the magnified image of the filter; the industrial camera 12 is mainly used for image acquisition and analysis; preferably, the industrial camera 12 uses a global shutter CMOS camera to avoid motion blur.

[0072] In this embodiment, as Figures 1 to 4As shown in the figure, the vision inspection mechanism (frame, optical magnification component 13, industrial camera 12) realizes the automatic inspection of the position accuracy, colloid state and defects of the mounted filter through high-precision optical imaging and image analysis technology. Specifically: when the optical device body with the first filter mounted is cured and before being conveyed to the angle flipping mechanism 16, it will first be moved to the vision inspection station. The optical magnification component 13 focuses on the filter mounting area on the optical device body, and at the same time the industrial camera 12 is started to capture and analyze the image, and 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 inspection, and complete the determination of the filter position, colloid state and surface defects (scratches, contamination) in a single shot; when it is detected that the optical device body is a qualified part, it is conveyed to the next process; when it is detected that the optical device body is an unqualified part, it is marked and removed by the sorting mechanism.

[0073] That is, the vision inspection mechanism forms a closed-loop quality monitoring system through the high-definition imaging of the optical magnification component 13 and the intelligent analysis of the industrial camera 12, solves the problems of low efficiency and strong subjectivity of manual inspection, and is especially suitable for the production of optical devices with strict requirements for mounting accuracy and glue quality, ensuring that the mounting state of each filter meets the design standards.

[0074] In this embodiment, the sorting mechanism includes a push rod assembly 14, a driving member and a recycling box; the push rod assembly 14 is arranged perpendicular to the conveying direction of the optical device body, and the push rod assembly 14 moves perpendicular to the conveying direction to laterally push the NG parts out of the sorting station conveyor track, and the qualified parts continue to move forward; and it is arranged close to the vision 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 to ensure that the action of the push rod assembly 14 is strictly aligned with the position of the optical device body; the end of the push rod assembly 14 is made of a flexible material, such as silica gel, to avoid impact damage to the workpiece; optionally, the push rod assembly 14 is provided with a lifting module to adapt to optical device bodies of different thicknesses; the driving member is connected to the push rod assembly 14; the driving member is used to drive the push rod assembly 14 to perform the sorting action; preferably, the driving member uses a cylinder (pneumatic drive) or a linear motor (electric drive) to meet the sorting requirements; the recycling box is arranged on the side away from the push rod assembly 14; the recycling box is used to collect the unqualified optical device bodies; preferably, the inner wall of the recycling box is attached with a buffer material to avoid secondary pollution caused by the bouncing of the NG parts.

[0075] In this embodiment, as Figures 1 to 4As shown, the sorting mechanism (push rod assembly 14, driving member, recycling box) works in cooperation with the vision inspection mechanism to achieve automatic sorting of the optical device body parts and rejection of defective products, ensuring that only qualified products flow into the next process. Specifically: after the vision inspection mechanism completes the quality determination of the optical device body parts, it transmits signals to the control system of the sorting mechanism, marking the workpieces as qualified (PASS) or unqualified (NG). If it is an NG part, the conveying mechanism of the curing mechanism 11 pauses. At this time, the driving member pushes the push rod assembly 14 to move horizontally, pushing the NG part into the recycling box, and the push rod resets; if it is a PASS part, the conveying mechanism of the curing mechanism 11 continues to operate, and the qualified parts flow into the next station, that is, into the angle flipping mechanism 16; that is, through the precise triggering of vision discrimination, the rapid response of the push rod assembly 14, and the orderly collection of the recycling box, the sorting mechanism forms an efficient quality closed-loop control, solving the problems of low efficiency and high missed inspection rate in traditional manual sorting, and is especially suitable for automated production lines with high-precision requirements such as optical devices, ensuring 100% rejection of defective products and the non-destructive passing of qualified products.

[0076] In this embodiment, the angle flipping 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 parts that have been mounted and cured after passing through the first mounting station; preferably, the rotating platform uses vacuum adsorption or mechanical fixtures to fix the optical device body parts to prevent slipping during rotation; the motor is arranged on the rotating platform; preferably, the motor drives the rotating platform through a speed reducer or direct drive method, with stable torque and 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 encoder 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 rotation of the motor; the proximity sensor is arranged on the rotating platform, preferably, the proximity sensor uses an inductive or photoelectric proximity sensor to detect whether there is an optical device body part in place on the rotating platform; when the proximity sensor senses that the optical device body part with 0° pasting completed is transported to the designated position, it will achieve precise adjustment of the optical device body within the range of 0° to 45°, meeting the precondition for the mounting of the 45° filter; if an optical device body part is detected, a signal is sent to the control system to allow the motor to start rotating; if no optical device body part is detected, the flipping process is paused and an alarm is given to avoid idling loss.

[0077] In this embodiment, as Figures 1 to 4As shown, the angle flipping mechanism 16 (rotating platform, motor, angle encoder, proximity sensor) through precise coordinated control realizes the precise angle flipping of the laser body part (such as rotating from 0° to 45°) after the first filter is mounted, to meet the mounting requirements of the combined filter. Specifically: The first mounting station mounts the 0° filter onto the laser body part and completes curing. The laser body part is conveyed from the curing mechanism 11 to the rotating platform. The proximity sensor detects the signal and triggers the control system to prepare for flipping. The motor starts, drives the rotating platform to rotate, and the angle encoder real-time feedbacks the angle. When the preset angle (such as 45°) is reached, the motor stops. After the flipping is completed, the rotating platform locks the angle. The conveying mechanism of the second mounting station transfers the laser body part to the second mounting station for dispensing and pasting of the 45° filter. Then the rotating platform resets to the initial position. That is, the angle flipping mechanism 16 through sensor triggering, motor drive, and encoder closed-loop feedback precise control solves the core problem of multi-angle combined filter mounting, especially suitable for optical communication devices with combined filters that require specific angle superpositions such as 0° and 45°, realizing high-repeatability and high-reliability automated production.

[0078] In this embodiment, as Figure 5 shown, the housing 17 is further provided with a plurality of air outlets, and the air outlets communicate with the accommodation cavity; each air outlet is correspondingly provided with a fan 19 to form a local air flow cycle, 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 passing through the rotating platform to cool the laser body part that has completed the 0° pasting before dispensing for the 45° pasting to ensure that the dispensing does not cure. In addition, the fan 19 exhausts air outward, making the accommodation cavity form a slight negative pressure to prevent external dust from invading. That is, this heat dissipation system through the collaborative design of distributed fans 19 + intelligent temperature control solves the pain points of precise optical equipment being sensitive to temperature and having low dust tolerance, not only ensuring the process stability of filter mounting but also extending the service life of the equipment, which is the key support for the high-reliable operation of the automated mounting equipment.

[0079] It should be known that, as Figure 5 shown, the main functions of the housing 17 are, one is to prevent dust from intervening during the pasting process, and the other is to prevent problems caused by human touch during the mechanical operation process; a warning light 18 is also configured above the housing 17, and once a problem occurs during operation, it will sound and light a warning until the problem is solved; in addition, a problem handling button is provided on the front of the housing 17; it should be known that the accommodation cavity of the housing 17 is divided into a first accommodation cavity and a second accommodation cavity by the bottom plate 20. The first accommodation cavity is mainly used to realize the erection of the entire design scheme, while the second accommodation cavity is to organize and collect all the used routes to prevent the lines from being messy.

[0080] In this embodiment, as Figure 1 and Figure 2 shown, it further includes a supplementary light component, and the supplementary light component is arranged in the accommodation cavity; the supplementary light component includes a fixed frame 1, a camera and a supplementary light screen 2; the supplementary light screen 2 is movably connected to the fixed frame 1 and is arranged corresponding to the feeding mechanism; preferably, the supplementary light screen 2 adopts an LED array or a light guide plate to emit diffused light to eliminate the reflection or shade on the surface of the optical device body; preferably, the supplementary light screen 2 is connected to the fixed frame 1 through a slide rail or a hinge, and the angle of the supplementary light screen 2 can be adjusted; the supplementary light screen 2 is provided with positioning holes; the camera passes through the positioning holes and is connected to the fixed frame 1; the camera passes through the positioning holes and is coaxial with the positioning holes, and aims at the optical device body on the flexible vibrating disk 3, avoiding the imaging field of view being blocked by the supplementary light screen 2, and ensuring that the intelligent recognition camera can have sufficient bright light sources in a closed space.

[0081] In this embodiment, as Figure 1 and Figure 2 shown, the supplementary light component (fixed frame 1, supplementary light screen 2, camera) works in cooperation with the feeding mechanism. Through dynamic supplementary lighting and visual positioning technology, it solves the problem of low-contrast recognition of the optical device body during the feeding process, and ensures the accuracy and reliability of the robot 5 for grasping. Specifically: the optical device body enters the feeding station of the flexible vibrating disk 3 from the body placement disk 4, and the flexible vibrating disk 3 stops vibrating; at this time, the brightness of the supplementary light screen 2 is automatically adjusted according to the workpiece material, the camera takes a picture of the optical device body through the positioning holes, and extracts the center coordinates and rotation angle of the optical device body; the data is transmitted to the robot 5 to correct the position and posture of the gripper 6; after the robot 5 finishes grasping, the brightness of the supplementary light screen 2 drops to the standby mode. That is, through the closed-loop cooperation of dynamically adjustable lighting and coaxial visual positioning, this supplementary light component overcomes the recognition problem caused by diverse materials during the feeding of optical devices, 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 the automatic mounting equipment.
