Description

Technical Field

[0001] This invention relates to the field of optical communication technology, specifically to a FA coupling device and its coupling method. Background Technology

[0002] During the coupling process between the optical module and the FA (Fiber Array), the MPO plug of the MPO (Multi-fiber Push On) fiber optic patch cord needs to be plugged into the optical module, and then the FA is coupled to the optical module. The cleanliness requirements of the MPO plug end face are particularly high, so the MPO plug needs to be cleaned before each plugging.

[0003] In the current production process, FA coupling can only achieve automatic coupling and automatic dispensing and curing. The loading and unloading of optical modules and FA, the cleaning and inspection of MPO fiber optic patch cords, and plugging and unplugging all need to be done manually. The entire process involves too much manual intervention and is not automated enough. Moreover, it requires high skills from the operators, resulting in low coupling efficiency, which is not conducive to mass production. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an FA coupling device and its coupling method. The optical module and FA of the product are clamped together on the outer bracket. The automatic loading and unloading of the optical module and FA is realized through the feeding flow module and the handling mechanism. The cleaning module, detection module and plug-in module realize the cleaning, detection and plug-in of the MPO plug, thereby reducing the skill requirements of the operator and improving the coupling efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] In a first aspect, an FA coupling device is provided, including a feeding flow line module for conveying an outer bracket. One side of the feeding flow line module is provided with a handling mechanism, a cleaning module, a detection module, and a fixture module. The fixture module includes a first fixture and a second fixture that can be opened and closed relative to each other. The first fixture is used to clamp the outer bracket, and the outer bracket is used to clamp a product, including an optical module and an FA. The second fixture is used to clamp an MPO fixture, and the MPO fixture is used to clamp an MPO plug that can be plugged into the optical module.

[0007] The cleaning module includes a cleaning component, a wiping component, and a first driving mechanism. The first driving mechanism is used to drive the MPO plug to be inserted into the cleaning port of the cleaning component or the wiping port of the wiping component.

[0008] The detection module includes a detection component and a second driving mechanism, the second driving mechanism being used to drive the MPO plug to be inserted into the detection port of the detection component;

[0009] The transport mechanism is used to transport the outer support between the feeding flow module and the first fixture, and to transport the MPO fixture between the first drive mechanism, the second drive mechanism and the second fixture.

[0010] Optionally, the fixture module further includes a fixture Y-axis linear module and a pluggable Y-axis linear module that are parallel to each other. The output end of the fixture Y-axis linear module is connected to a first base plate for mounting the first fixture, and the output end of the pluggable Y-axis linear module is connected to a second base plate for mounting the second fixture.

[0011] Optionally, the first fixture is provided with a clamping mechanism for clamping the product on one side near the second fixture, and a power supply mechanism for supplying power to the product on the other side.

[0012] Optionally, the jig module is provided with a coupling module for coupling the FA to the optical module on its outer side, and a dotted vision module is provided on the top of the jig module.

[0013] Optionally, the first drive mechanism includes a shifting X-axis linear module located on the same side of the cleaning port and the wiping port. The output end of the shifting X-axis linear module is connected to a first insertion and extraction linear module, and the output end of the first insertion and extraction linear module is connected to a lateral insertion and extraction gripper for clamping the MPO fixture.

[0014] Optionally, the second drive mechanism includes a support for supporting the MPO fixture, and a second insertion / extraction linear module is provided on the side of the support opposite to the detection port. The output end of the second insertion / extraction linear module is connected to a longitudinal insertion / extraction gripper for clamping the MPO fixture.

[0015] Optionally, the feeding flow line module includes a flow line body, one end of which is provided with a feeding mechanism and the other end with a discharging mechanism. The flow line body includes a discharge section, a positioning section and a receiving section connected in sequence. The feeding mechanism is close to the discharge section, the discharging mechanism is close to the receiving section, and the conveying mechanism conveys the outer support from the positioning section.

[0016] Optionally, the handling mechanism includes a multi-axis robot, the output end of which is connected to a mounting frame. A first gripper assembly for gripping an outer support is mounted on one side of the mounting frame, and a support plate is rotatably mounted on the other side. Two second gripper assemblies for gripping MPO fixtures are arranged opposite each other on the support plate.

[0017] Secondly, a coupling method for an FA coupling device is provided, implemented using the FA coupling device described in the first aspect, comprising the following steps:

[0018] S1. The conveying mechanism moves the outer bracket carrying the product to be coupled from the feeding flow module to the first fixture, and uses the clamping mechanism to clamp and fix the product, and uses the power supply mechanism to power the optical module.

[0019] S2. While the product is fixed and powered on on the first fixture, the transport mechanism transports the MPO plug that has completed the end face inspection, together with the MPO fixture, to the second fixture.

[0020] S3. After the MPO fixture is placed on the second fixture, the first fixture and the second fixture are brought closer together until the MPO plug is inserted into the optical module. Then the coupling module and the dispensing vision module work together to complete the coupling between the FA and the optical module.

[0021] After S4 and FA are coupled with the optical module, the coupling module, clamping mechanism and power supply mechanism are reset, the MPO plug is pulled out, the conveying mechanism puts the outer bracket carrying the coupled product back into the feeding flow line module, the feeding flow line module unloads the product and provides the outer bracket carrying the product to be coupled.

[0022] Optionally, two sets of MPO fixtures with MPO plugs are provided. When replacing them in step S2: one of the second gripper components of the transport mechanism first grabs the MPO fixture that has completed the MPO plug end face inspection, and then the other second gripper component picks up the used MPO fixture from the second fixture. Finally, the MPO fixture that has completed the MPO plug end face inspection is placed on the second fixture. During the coupling process between the FA and the optical module, the transport mechanism transports the used MPO fixtures to the cleaning module and the inspection module in sequence for end face cleaning and inspection, respectively.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] (1) In this invention, the optical module and FA of the product are clamped together on the outer bracket, and the MPO plug is clamped on the MPO fixture, which facilitates the handling mechanism to handle and load and unload the material. The first drive mechanism realizes automatic cleaning at the cleaning component and automatic wiping at the wiping component, and the second drive mechanism realizes automatic detection at the detection component. While ensuring the cleanliness of the MPO plug end face, the automation level of the production process is greatly improved, the dependence on personnel is reduced, the stability of production quality is improved and the yield is increased.

[0025] (2) In this invention, the end of the multi-axis robot of the handling mechanism is provided with two sets of grippers, which are used to grip the outer support and the MPO fixture respectively. The two sets of grippers are integrated into the same end of the multi-axis robot, which facilitates the gripping work and reduces the production cost. There are two second gripper components for gripping the MPO fixture, which facilitates the replacement of the MPO fixture and improves the overall coupling efficiency.

[0026] (3) In this invention, the placement of the outer support and the MPO fixture is independent of each other, and while the product is positioned and powered on on the first fixture, the transport mechanism performs transport operations on the MPO fixture, saving time, improving work efficiency, and reducing coupling costs.

[0027] (4) In this invention, there are two sets of MPO fixtures that hold MPO plugs, which can be used interchangeably. When one set participates in the coupling operation, the other set can perform plug end face cleaning and inspection work through the cleaning module and the detection module under the action of the transport mechanism, in order to prepare for the next round of coupling operation. This method can enable the modules and mechanisms to cooperate with each other, save time, and improve the coupling efficiency of the coupling equipment. Attached Figure Description

[0058] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0059] Example 1, as Figure 1 and Figure 2 As shown, an FA coupling device includes a coupling section and a loading / unloading section. The coupling section is located in front of the loading / unloading section and is equipped with a separate air flotation vibration damping system to isolate the loading / unloading section from external vibrations. The loading / unloading section is equipped with vibration damping pads to absorb vibrations. The coupling section is integrally arranged on a second platform 11, with the air flotation vibration damping system arranged below the second platform 11. The loading / unloading section is integrally arranged on a first platform 10, with five vibration damping pads arranged below the first platform 10. The first platform 10 and the second platform 11 are independent of each other, with the first platform 10 using a large base plate and the second platform 11 using a marble platform.

[0060] To facilitate product loading, unloading, and handling, the product's FA and optical module are integrated onto the outer bracket 9. During loading, unloading, and handling, only the outer bracket 9 needs to be operated, i.e., the product, including the optical module and FA, is clamped on the outer bracket 9. Similarly, the MPO plugs of the fiber optic patch cords required during coupling are clamped together using the MPO clamp 8, so that the working end of the MPO plug protrudes from the MPO clamp 8. During the coupling, cleaning, and testing of the MPO plug, the MPO clamp 8 can be used for handling, clamping, and positioning.

[0061] The outer support 9 and the MPO fixture 8 are existing technologies, so their structures will not be described in detail here.

[0062] The loading and unloading section includes a feeding flow module 1, a conveying mechanism 5, a cleaning module 6, and a detection module 7. The conveying mechanism 5 is located in the center of the first platform 10 and is used to pick up and place the outer support 9 and the MPO fixture 8. The feeding flow module 1 is located behind the conveying mechanism 5 and is used to pick up and place the tray containing the outer support 9 from the material cage and to lift and position the tray. The cleaning module 6 and the detection module 7 are located on the left and right sides of the conveying mechanism 5, respectively. The former is used to clean and wipe the MPO plug end face, and the latter is used to detect whether the cleanliness of the MPO plug end face meets the coupling requirements.

[0063] The coupling section includes a fixture module 2, a coupling module 3, and a dispensing vision module 4. The fixture module 2 is located in the center of the second platform 11, the coupling module 3 is located to the left and / or right of the fixture module 2, and the dispensing vision module 4 is located above the fixture module 2. The fixture module 2 is used to support the outer bracket 9 and the MPO fixture 8, and to connect the MPO plug to the optical module. The coupling module 3 is used to couple the FA and the optical module on the outer bracket 9, while the dispensing vision module 4 is used for dispensing and curing to ensure the coupling connection between the FA and the optical module.

[0064] Specifically, the transport mechanism 5 can transport the outer bracket 9 from the feeding flow module 1 to the fixture module 2, and transport the MPO fixture 8 to the cleaning module 6 and the inspection module 7. After the MPO plug end face on the MPO fixture 8 passes the inspection module 7, the transport mechanism 5 transports the MPO fixture 8 to the fixture module 2, so that the MPO plug and the optical module can be connected. After the product is powered on, the dispensing vision module 4 works with the coupling module 3 to complete the coupling between the FA and the optical module. After the coupling is completed, the outer bracket 9 is transported back to the feeding flow module 1 through the transport mechanism 5. The MPO fixture 8 is processed again by the cleaning module 6 and the inspection module 7 to prepare for the next coupling.

[0065] In Example 2, the present invention also proposes a specific structure for the coupling part.

[0066] like Figures 5-8 As shown, the fixture module 2 includes a fixture Y-axis linear module 201 and a pluggable Y-axis linear module 207 mounted on the second platform 11, which are parallel to each other. A first base plate 202 is mounted on the output end of the fixture Y-axis linear module 201, and a first fixture 203 for clamping the outer support 9 is mounted on the first base plate 202. A second base plate 208 is mounted on the output end of the pluggable Y-axis linear module 207, and a second fixture 209 for clamping the MPO fixture 8 is mounted on the second base plate 208.

[0067] Specifically, the first base plate 202 and the second base plate 208 are relatively distributed and can be opened and closed relative to each other under the drive of their respective corresponding Y-axis linear modules. Based on this, the first fixture 203 and the second fixture 209 can be opened and closed relative to each other through the two base plates, thereby realizing the insertion and removal between the MPO plug on the MPO fixture 8 and the optical module on the outer bracket 9.

[0068] As described above, the first fixture 203 includes a platform for supporting the outer bracket 9. The platform is connected to the first base plate 202 through an angle adjustment component. That is, the attitude of the outer bracket 9 on the platform can be adjusted in space through the angle adjustment component to ensure that the MPO plug corresponds to the socket on the product and improve the accuracy of their mating.

[0069] The angle adjustment component can drive the stage to achieve rotational adjustment around the X-axis, Y-axis and Z-axis. The angle adjustment component, the fixture Y-axis linear module 201 and the plug-in Y-axis linear module 207 all adopt existing technologies, so they will not be described in detail here.

[0070] Furthermore, the first base plate 202 is also provided with a clamping mechanism 204 and a power supply mechanism 205. The clamping mechanism 204 is located on the side of the first fixture 203 closer to the second fixture 209, and the power supply mechanism 205 is located on the side of the first fixture 203 away from the second fixture 209. The clamping mechanism 204 is used to clamp the product onto the first fixture 203 to facilitate subsequent mating with the MPO plug, and the power supply mechanism 205 is used to supply power to the product to facilitate coupling.

[0071] The clamping mechanism 204 includes a sleeve 241 connected to the first fixture 203. A telescopic component 245 is rotatably installed inside the sleeve 241. A clamping ring 242 is connected to the output end of the telescopic component 245. Guide wheels 244 are rotatably installed on both sides of the clamping ring 242. An inverted L-shaped guide groove 243 is opened on the side of the sleeve 241, and the guide wheel is embedded in the guide groove 243 and can move along the guide groove 243.

[0072] Specifically, the clamping ring 242 adopts a rectangular structure, and the telescopic component 245 can be a cylinder. When the output end of the telescopic component 245 extends, the clamping ring 242, driven by it, can move upward along the guide groove 243 through the guide wheel 244. Since the telescopic component 245 is rotatably connected to the sleeve 241 and the clamping ring 242, it can also drive the guide wheel 244 to move into the horizontal section of the guide groove 243. At this time, the upper part of the clamping ring 242 tilts away from the second fixture 209, so that the product can be released from the clamping ring 242.

[0073] When the output end of the telescopic assembly 245 retracts, the clamping ring 242 moves in the opposite direction and flips from the inclined position, so that the end of the product passes through the clamping ring 242. At this time, the guide wheel 244 enters the vertical section of the guide groove 243. As the telescopic assembly 245 continues to retract, the clamping ring 242 moves down and firmly clamps the product through the inner top surface, thereby fixing the product on the first fixture 203 platform, which facilitates subsequent operations.

[0074] The clamping mechanism 204 has a simple and reasonable structure, is easy to operate, and can achieve the functions of avoiding interference before loading and clamping after loading. It avoids interference between the clamping ring 242 and the gripper of the product or handling mechanism 5 during loading and unloading, and significantly improves the efficiency and operational stability of the equipment.

[0075] The power supply mechanism 205 includes a lifting component 251 connected to the first base plate 202. The output end of the lifting component 251 is connected to a translation component 252, and the output end of the translation component 252 is equipped with a probe plate 253. After the outer bracket 9 is placed on the first fixture 203 and its posture is adjusted, the translation component 252 drives the probe plate 253 to move above the optical module probe port. Then, the lifting component 251 drives the probe plate 253 to move down until the probe and the probe port are engaged to complete the power supply connection.

[0076] The lifting component 251 and the translation component 252 can both be implemented using existing technologies such as cylinders that output linear motion. The power supply mechanism 205 adopts a top-down plug-in power supply method, which is not only highly efficient but also more precise, ensuring the reliability of power supply to the product.

[0077] The second fixture 209 includes a support base 291 mounted on a second base plate 208. A positioning seat 292 is fixedly mounted on the top of the support base 291, and a positioning component 293 is mounted on the side of the positioning seat 292 opposite to the first fixture 203. When the MOP fixture is placed on the positioning seat 292, the positioning component 293 abuts against it from the end of the MPO fixture 8 opposite to the MPO plug, thereby achieving the clamping and positioning function.

[0078] As described above, the positioning seat 292 is provided with a positioning groove that is compatible with the MPO fixture 8, and a groove for the MPO plug to pass through is provided on the side of the positioning groove near the first fixture 203; the positioning assembly 293 includes a telescopic cylinder connected to the support seat 291, and a positioning plate is installed at the output end of the telescopic cylinder.

[0079] Specifically, after the MPO clamp 8 is inserted into the positioning groove, the MPO plug extends through the groove to the outside of the positioning seat 292. Then, the telescopic cylinder pushes the positioning plate to extend, and the positioning plate abuts against the end of the MPO clamp, thereby pushing the other end of the MPO clamp 8 to abut against the inner wall of the positioning groove, completing the positioning and fixing of the MPO clamp 8 on the positioning seat 292, and improving the convenience of clamping the MPO clamp 8.

[0080] like Figure 10 As shown, the coupling module 3 includes a coupling X-axis linear module 301 mounted on the second platform 11. A coupling Y-axis linear module 302 is mounted on the output end of the coupling X-axis linear module 301. A coupling Z-axis linear module 303 is mounted on the output end of the coupling Y-axis linear module 302. An angle adjustment module 304 is mounted on the output end of the coupling Z-axis linear module 303. An FA gripper 305 is connected to the output end of the angle adjustment module 304. An FA suction nozzle 306 is connected to the lower part of the FA gripper 305.

[0081] Among them, the X-axis linear module 301, the Y-axis linear module 302, and the Z-axis linear module 303 all adopt existing technologies and can drive the FA gripper 305 and the FA nozzle 306 to achieve translation along the X, Y, and Z axes. The angle adjustment module 304 also adopts existing technologies and can realize the rotation of the FA gripper 305 and the FA nozzle 306 around the X, Y, and Z axes. The FA gripper 305 is an electric gripper. After the FA gripper 305 and the FA nozzle 306 of the coupling module 3 grip the FA, they can move freely within a certain range of space to adjust their posture in order to achieve coupling between the FA and the optical module.

[0082] like Figure 9 , Figures 11-12 As shown, the dispensing and curing assembly 405 of the dispensing vision module 4 includes a frame 451. A vision camera 452 is installed on the rear side inside the frame 451, and a UV lifting component 453 is installed in the middle. The output end of the UV lifting component 453 is connected to a UV lamp head 454. A dispensing lifting component 455 is installed on the front side outside the frame 451, and the output end of the dispensing lifting component 455 is connected to a dispensing head 456.

[0083] Both the UV lifting component 453 and the dispensing lifting component 455 can be cylinders. The vision camera 452, UV lamp head 454, and dispensing head 456 are all existing technologies. The vision camera 452 is used to take pictures and realize positioning and glue quantity detection through visual recognition technology. The dispensing head 456 is used to dispense glue at the coupling position of the light module. The UV lamp head 454 illuminates the dispensing position with a UV lamp to quickly cure it.

[0084] The dispensing and curing assembly 405 is located above the fixture module 2 and can move in space along the X, Y, and Z axes to facilitate dispensing, curing, and visual recognition.

[0085] Specifically, two gantry frames 401 are fixedly installed on the second platform 11. The two gantry frames 401 are arranged opposite each other on the left and right sides of the fixture module 2, and the tops of the two gantry frames 401 are connected by a crossbeam. One of the gantry frames 401 has a translation Y-axis linear module 402 installed on its top surface. The output end of the translation Y-axis linear module 402 is connected to the crossbeam, thereby realizing the movement of the crossbeam along the Y-axis direction.

[0086] A translation X-axis linear module 403 is installed at the bottom of the crossbeam. The output end of the translation X-axis linear module 403 is connected to a lifting Z-axis linear module 404. The output end of the lifting Z-axis linear module 404 is connected to the frame 451 of the dispensing curing component 405, thereby enabling the dispensing curing component 405 to move along the X, Y, and Z axes.

[0087] Among them, the translation X-axis linear module 403, translation Y-axis linear module 402 and lifting Z-axis linear module 404 all adopt existing linear modules. The gantry 401, which does not have the translation Y-axis linear module 402 installed, is equipped with a guide rail slider on the top to support the crossbeam and ensure that it is in a horizontal state.

[0088] Furthermore, a glue-wiping mechanism 206 is also provided on the first base plate 202 to clean the glue dispensing head 456 and ensure that the glue dispensing amount is reasonable and accurate. The glue-wiping mechanism 206 includes a mounting base 261 connected to the first base plate 202. A gripper component 262 is fixedly mounted on the mounting base 261. The gripper component 262 is a pneumatic gripper. A glue-wiping pad 263 is installed on the inner side of the pneumatic gripper. As the pneumatic gripper opens and closes, the two glue-wiping pads 263 open and close synchronously.

[0089] After the dispensing head 456 has been used for a period of time, it moves between the two adhesive pads 263. The two adhesive pads 263 close relative to each other, and the dispensing head 456 moves up, down, left, and right to remove the adhesive, so that the end of the dispensing head 456 is unobstructed and its dispensing volume is accurate.

[0090] In addition, a support block 264 is fixedly installed on one side of the gripper component 262. The support block 264 is made of stainless steel. After the glue is applied, or when it is necessary to calibrate the glue dispensing amount, the glue can be applied to the top surface of the support block 264, and then the visual camera 452 can be used to take pictures and check whether the glue dispensing amount is normal.

[0091] Workflow of the coupled component:

[0092] The transport mechanism 5 clamps the outer bracket 9 to the first fixture 203, the clamping mechanism 204 clamps the product to fix it, and the probe plate 253 of the power supply mechanism 205 is inserted into the product to connect the circuit; the transport mechanism 5 clamps the MPO fixture 8 that has passed the end face inspection to the second fixture 209, and the positioning plate of the positioning component 293 abuts against the MPO fixture 8 to complete its positioning; then the first fixture 203 and the second fixture 209 move relative to each other to realize the insertion of the MPO plug and the optical module;

[0093] The vision camera 452 positions the FA and the optical module. Then, the FA gripper 305 and FA nozzle 306 of the coupling module 3 grip the FA and pre-couple the FA and the optical module. After pre-coupling, the dispensing head 456 moves to the coupling position to dispense adhesive. Then, the coupling module 3 couples the FA and the optical module with adhesive. After coupling is completed, the UV lamp head 454 moves to the coupling position to perform UV curing.

[0094] After the product coupling is completed and solidified, the coupling module 3 returns to its original position, the MPO plug is pulled out, the probe plate 253 is pulled out, and the clamping mechanism 204 releases the clamping on the product. Finally, the conveying mechanism 5 puts the coupled product along with the outer bracket 9 back into the positioning section 103 of the feeding flow line module 1, and replaces the used MPO plug.

[0095] In Example 3, the present invention also proposes a specific structure for the loading and unloading section.

[0096] like Figure 3 and Figure 4 As shown, the feeding flow line module 1 includes a flow line body, a feeding mechanism 101, and a discharging mechanism 105. The feeding mechanism 101 and the discharging mechanism 105 are respectively installed at both ends of the flow line body. The feeding mechanism 101 is used to provide the product to be coupled, and the discharging mechanism 105 is used to collect and store the coupled product. The flow line body is used to transport the product from the feeding mechanism 101 to the discharging mechanism 105. During the transportation process, the handling mechanism 5 transports the product to be coupled from the flow line body to the coupling part, and transports the coupled product back from the coupling part to the flow line body, and then the flow line body transports it to the discharging mechanism 105 to realize the unloading.

[0097] The main body of the streamline includes a discharge section 102, a positioning section 103 and a receiving section 104 connected in sequence. The loading mechanism 101 is close to the discharge section 102, the unloading mechanism 105 is close to the receiving section 104, and the conveying mechanism 5 moves the outer support 9 from the positioning section 103 and transports the coupled product along with the outer support 9 back to the positioning section 103.

[0098] The discharge section 102 and the receiving section 104 are arranged opposite to each other and have the same structure. Both include a first streamline frame. The inner side of the first streamline frame is provided with a conveyor belt and a hook that can be lifted and moved horizontally. The lifting of the hook is achieved by a lifting cylinder, and the horizontal movement is achieved by a transmission belt. The conveyor belt is located above the first streamline frame, and the transmission belt is located below the conveyor belt. The two work in the same direction.

[0099] The lifting cylinder is fixedly connected to one side of the transmission belt, and the output end of the lifting cylinder is fixedly connected to the hook. The inner wall of the first streamline frame is fixedly installed with a linear rail in the same working direction as the transmission belt and the conveyor belt. The linear rail is slidably connected to the lifting cylinder, which can support and guide the lifting cylinder, and ensure the accuracy and stability of material discharge and collection.

[0100] The positioning section 103 includes a second streamline frame. Inside the second streamline frame, there is a stop component 131 and a lifting component 132. The stop component 131 is a stop cylinder, which is installed at an angle on the second streamline frame near the receiving section 104. That is, the upper end of the stop cylinder is close to the discharge section 102 and the lower end is close to the receiving section 104. The lifting component 132 is a lifting cylinder, and a lifting plate is installed at its output end. A conveyor belt is also installed on the upper part of the inner side of the second streamline frame.

[0101] The feeding mechanism 101 and the unloading mechanism 105 are arranged opposite to each other and have the same structure, both including a support plate, a material cage, and a lifting drive assembly. The output end of the lifting drive assembly is connected to the support plate, and the material cage is placed on the support plate. Under the combined action of the lifting drive assembly and the support plate, the material cage can be lifted and lowered. The lifting drive assembly adopts a screw and nut drive structure. The support plate is fixedly connected to the nut, and the nut is screwed onto the screw. When the motor drives the screw to rotate, the nut can move along the axis of the screw, thereby driving the support plate to lift and lower.

[0102] To improve the stability of the support plate's lifting and lowering, guide rods can be fixedly installed on both sides of the lead screw. The guide rods are parallel to the lead screw and slide through the support plate, thereby playing a role in limiting and guiding.

[0103] Workflow of feeding assembly line module 1:

[0104] The material cage of the feeding mechanism 101 contains stacked trays, and each tray is equipped with an outer bracket 9. The outer bracket 9 integrates the product's FA and optical module. The material cage of the unloading mechanism 105 is an empty material cage used to store the coupled product. The material cage of the feeding mechanism 101 moves down layer by layer, and the material cage of the unloading mechanism 105 moves up layer by layer.

[0105] When discharging, the hook of the discharge section 102 moves to one end close to the feeding mechanism 101, and then moves upward so that the hook hooks the bottom tray of the material cage. Then it moves horizontally to the positioning section 103 until the tray is completely detached from the material cage, so that the two ends of the tray overlap the conveyor belt. Then the hook moves downward to detach from the tray, and the conveyor belt transports it to the positioning section 103.

[0106] Once the pallet has moved into position with the conveyor belt of the positioning section 103, the blocking component 131 is activated to intercept and stop it. Then, the lifting component 132 is activated to lift it off the conveyor belt, where it is supported by the lifting plate. This facilitates the handling mechanism 5 to grab the outer support 9 on the pallet and place the outer support 9 on the pallet. After the outer support 9 is placed back on the pallet, the lifting component 132 is reset, and the pallet is reattached to the conveyor belt. Then, the blocking component 131 is reset, and the pallet continues to move towards the receiving section 104.

[0107] During material collection, the hook of the receiving section 104 moves to a position close to the positioning section 103, the hook moves up and hooks the pallet, and then moves to the feeding mechanism 105 until the pallet is completely pushed into the material cage of the feeding mechanism 105.

[0108] like Figure 13 As shown, the conveying mechanism 5 is used to convey the outer support 9 between the feeding flow module 1 and the first fixture 203, and to convey the MPO fixture 8 between the first drive mechanism, the second drive mechanism and the second fixture 209.

[0109] The handling mechanism 5 includes a multi-axis robot 501. The output end of the multi-axis robot 501 (e.g., a six-axis robot) is connected to a mounting frame 502. A first gripper assembly 503 and a second gripper assembly 505 are respectively arranged on opposite sides of the mounting frame 502. The first gripper assembly 503 is used to grip the outer support 9, and the second gripper assembly 505 is used to grip the MPO fixture 8. The first gripper assembly 503 uses a pneumatic gripper adapted to the outer support 9, and the second gripper assembly 505 uses a pneumatic gripper adapted to the MPO fixture 8. Both are existing technologies and will not be described in detail here.

[0110] Furthermore, the first gripper assembly 503 is fixedly connected to the mounting bracket 502 via an L-shaped plate. A drive motor is fixedly mounted on the mounting bracket 502, and the output end of the drive motor is connected to a support plate 504. The second gripper assembly 505 is mounted on the support plate 504.

[0111] MPO plugs are typically directional. When two MPO plugs are integrated on each MPO fixture 8, the two MPO plugs are arranged opposite each other. However, in order to ensure the accuracy of end face detection, only one MPO plug is detected at a time. Therefore, after one MPO plug is detected, it can be gripped by the second gripper assembly 505 and then rotated 180 degrees by the drive motor to the support plate 504 and placed again, thereby realizing the end face detection of the other MPO plug.

[0112] like Figure 14 and Figure 15 As shown, the cleaning module 6 includes a cleaning component, a wiping component, and a first driving mechanism. The cleaning component is used to clean the end face of the MPO plug, the wiping component is used to wipe the cleaned end face, and the first driving mechanism is used to drive the MPO plug to be inserted into the cleaning port 603 of the cleaning component or the wiping port 605 of the wiping component.

[0113] The cleaning assembly and the wiping assembly are arranged side-by-side along the X-axis. The cleaning assembly uses a cleaning device 601, with the cleaning port 603 located at the end of the cleaning head 602 of the cleaning device 601. The wiping assembly is located to one side of the wiping assembly and uses a wiping box 604, with the wiping port 605 located on the side of the wiping box 604. The wiping port 605 and the cleaning port 603 face the same direction. Both the cleaning assembly and the wiping assembly can use existing technology, and the end of the cleaning device 601 opposite to the cleaning head 602 is connected to the cleaning main unit via a pipe.

[0114] The first drive mechanism includes a shifting X-axis linear module 606, the output end of which is connected to a first insertion and removal linear module 607, the output end of which is connected to a transverse insertion and removal gripper 608 for holding the MPO fixture 8, and the shifting X-axis linear module 606 is located on the same side of the cleaning port 603 and the wiping port 605.

[0115] Specifically, after the transport mechanism 5 transports the MPO fixture 8 to the cleaning module 6, the horizontal insertion and removal jaws 608 complete the clamping and positioning. At this time, the MPO fixture 8 is in a horizontally flat state. Then, the X-axis linear module 606 first drives the MPO plug on the MPO fixture 8 to align with the cleaning port 603, and then the first insertion and removal linear module 607 drives the MPO plug on the MPO fixture 8 to insert into the cleaning port 603 for end face cleaning. After cleaning, the first insertion and removal linear module 607 drives the MPO plug to be pulled out, and the X-axis linear module 606 drives the MPO plug on the MPO fixture 8 to align with the wiping port 605, and the first insertion and removal linear module 607 drives it to be inserted into the wiping port 605 for wiping. After wiping, the MPO plug is pulled out, the horizontal insertion and removal jaws 608 release the MPO fixture 8, and then the transport mechanism 5 transports it to the detection module 7.

[0116] Furthermore, the X-axis linear module 606 is also equipped with a placement platform 609, which is used to receive the MPO fixture 8 and can serve as a temporary storage and transfer station.

[0117] like Figure 16 As shown, the detection module 7 is used to detect whether the cleanliness of the plug end face after wiping meets the coupling requirements. If the coupling requirements are met, the transport mechanism 5 transports the MPO fixture 8 to the second fixture 209; if the coupling requirements are not met, the transport mechanism 5 transports the MPO fixture 8 to the cleaning module 6 for re-cleaning and wiping.

[0118] The detection module 7 includes a detection component and a second driving mechanism. The detection component adopts a fiber optic end face detector 701, and the detection port is located on the side of the fiber optic end face detector 701. The detection is performed by taking pictures based on visual inspection technology. The second driving mechanism is used to drive the MPO plug to be embedded into the detection port of the detection component.

[0119] The second drive mechanism includes a support 702 for supporting the MPO fixture 8. A second insertion / extraction linear module 703 is provided on the side of the support 702 opposite to the detection port. The output end of the second insertion / extraction linear module 703 is connected to a longitudinal insertion / extraction jaw 704 for clamping the MPO fixture 8.

[0120] Specifically, the support 702 is located on one side of the detection component. When the MPO clamp 8 is placed on the support 702, the MPO plug faces the detection port. The longitudinal insertion and removal claw 704 clamps the MPO clamp 8 from the rear end. At this time, the MPO clamp 8 is in a horizontally upright state. Then, the longitudinal insertion and removal claw 704 is driven to move back and forth by the second insertion and removal linear module 703 to realize the insertion and removal between the MPO plug and the detection port.

[0121] The MPO clamp 8 can slide relative to the support 702. To improve the accuracy of insertion and removal, guide blocks for limiting and guiding are fixedly installed on both sides of the top of the support 702, so that the MPO clamp 8 can only move in the specified direction.

[0122] Furthermore, a position adjustment component is also provided at the bottom of the support 702 to adjust the position of the support 702 relative to the detection component in space, ensuring that the MPO plug is aligned with the detection port to accommodate MPO fixtures 8 of different specifications and sizes. The second insertion / removal linear module 703 is fixedly connected to the support 702, and the position adjustment component adopts existing technology, including but not limited to adjustment methods using multiple stacked positioning blocks and their elongated holes and screws.

[0123] In Example 4, after each coupling is completed, the MPO plug needs to be cleaned and inspected again. To improve production efficiency, the equipment of the present invention adopts a dual jumper design and is equipped with an optical switch for switching. The corresponding gripper of the robot gripping MPO fixture 8 also adopts a dual-grip design.

[0124] Two sets of MPO fixtures 8 are provided, each set holding two MPO connectors. The MPO connectors on the two sets of MPO fixtures 8 are connected to the same test equipment via two jumpers, and controlled by an optical switch. During coupling, the jumper corresponding to the MPO fixture 8 is turned on, while the unused jumper is turned off. This design not only improves coupling efficiency but also reduces production costs, requiring only one test equipment to enable the interchangeable use of the two sets of MPO connectors.

[0125] To facilitate the replacement of the MPO gripper 8, each multi-axis robot 501 is equipped with two second gripper assemblies 505 at its output end, and the two second gripper assemblies 505 are mounted opposite each other on the support plate 504.

[0126] Specifically, when replacing the MPO fixture 8, one of the second gripper assemblies 505 first picks up the qualified MPO fixture 8 from the support 702, and the other second gripper assembly 505 picks up the used MPO fixture 8 from the positioning seat 292. The two grippers rotate 180 degrees relative to each other, and then the MPO fixture 8 to be used is placed into the positioning slot of the positioning seat 292. Then, a coupling operation is performed. At this time, the replaced MPO fixture 8 is picked up by the conveying mechanism 5 and taken to the cleaning module 6 for cleaning, and then transported to the detection module 7 for detection.

[0127] Example 5: Depending on the product model, the coupling device proposed in this invention can also be modified accordingly. For example, for the TX model product and the RX model product, the former has only one coupling bit, and only one FA needs to be coupled to the optical module, while the latter has two coupling bits, so two FAs need to be coupled to the optical module at the same time.

[0128] For the TX model product, since there is only one coupling position on its optical module, the coupling device only needs one coupling module 3 to perform the coupling operation. At this time, the coupling device only has one coupling module 3, which is located on the left or right side of the fixture module 2.

[0129] Regarding the RX model product, since its optical module has two coupling positions, the coupling device has two coupling modules 3, located on the left and right sides of the fixture module 2 respectively. When the MPO plug is inserted into the optical module, the left and right coupling modules 3 respectively clamp the FA and simultaneously couple with the two corresponding coupling positions of the optical module (e.g., ...). Figure 5 and Figure 10 (As shown).

[0130] Example 6: Based on the foregoing examples, the present invention also proposes a coupling method for an FA coupling device, comprising the following steps:

[0131] The manual staff places the product cage to be coupled and the empty cage into the upper and lower material positions respectively, and places the MPO fixture 8 in the designated position. The outer support 9 is transported from the feeding flow module 1 to the first fixture 203. After the MPO fixture 8 is cleaned and inspected and qualified, it is transported to the second fixture 209. The first fixture 203 and the second fixture 209 drive the MPO plug to be inserted with the product, and then the coupling operation is performed. After the coupling is completed, the outer support 9 is transported back to the feeding flow module 1. Until the material in the cage of the feeding mechanism 101 is finished, the manual staff removes the empty cage and the coupled product cage.

[0132] The transport mechanism 5 transports the outer bracket 9 carrying the product to be coupled from the feeding flow module 1 to the first fixture 203. The product is clamped and fixed by the clamping mechanism 204, and the power supply mechanism 205 supplies power to the optical module. The transport mechanism 5 grips the outer bracket 9 of the positioning section 103 through the first gripper assembly 503 and transports it to the platform of the first fixture 203. The output end of the telescopic assembly 245 retracts, and the clamping ring 242 flips from the inclined position, so that the end of the product passes through the clamping ring 242. Then the clamping ring 242 moves down and firmly clamps the product through the inner top surface. After the outer bracket 9 is placed on the first fixture 203 and adjusted in posture, the translation assembly 252 drives the probe plate 253 to move above the probe port of the optical module. Then the lifting assembly 251 drives the probe plate 253 to move down until the probe and the probe port are engaged to complete the power supply connection.

[0133] While the product is fixed and powered on in the first fixture 203, the transport mechanism 5 transports the MPO plug that has completed end face inspection, along with the MPO clamp 8, to the second fixture 209. The second gripper assembly 505 of the transport mechanism 5 picks up the qualified MPO clamp 8 from the support 702 of the inspection module 7 and transports it into the positioning groove of the positioning seat 292. Then, the telescopic cylinder pushes the positioning plate to extend, and the positioning plate abuts against the end of the MPO clamp, thereby pushing the other end of the MPO clamp 8 against the inner wall of the positioning groove, completing the positioning and fixing of the MPO clamp 8 on the positioning seat 292.

[0134] In addition, after the transport mechanism 5 grabs the outer bracket 9, it can move to the detection module 7 to grab the qualified MPO fixture 8, and then transport the two together to the fixture module 2. First, the outer bracket 9 is placed on the first fixture 203. While the product of the outer bracket 9 is pressed and energized on the first fixture 203, the MPO fixture 8 is placed on the second fixture 209 or the MPO fixture 8 is replaced from the second fixture 209.

[0135] After the MPO fixture 8 is placed on the second fixture 209, the first fixture 203 and the second fixture 209 move closer together until the MPO plug is inserted into the optical module. The first base plate 202 and the second base plate 208 can move closer together under the drive of their respective corresponding Y-axis linear modules. Based on this, the two base plates drive the first fixture 203 and the second fixture 209 to move closer together, thereby realizing the insertion between the MPO plug on the MPO fixture 8 and the optical module on the outer bracket 9.

[0136] The coupling module 3 and the dispensing vision module 4 work together to couple the FA and the optical module. The vision camera 452 positions the FA and the optical module. Then, the FA gripper 305 and the FA nozzle 306 of the coupling module 3 grip the FA and perform pre-coupling between the FA and the optical module. After pre-coupling, the dispensing head 456 moves to the coupling position to dispense adhesive. Subsequently, the coupling module 3 couples the FA and the optical module with adhesive. After coupling is completed, the UV lamp head 454 moves to the coupling position to perform UV curing.

[0137] After the FA is coupled with the optical module, the coupling module 3, the clamping mechanism 204 and the power supply mechanism 205 are reset, the MPO plug is pulled out, the conveying mechanism 5 puts the outer bracket 9 carrying the coupled product back into the feeding flow module 1, the feeding flow module 1 unloads the product and provides the outer bracket 9 carrying the product to be coupled.

[0138] When the coupling module 3 is reset, its FA gripper 305 and FA suction nozzle 306 move away from the top of the fixture module 2. When the clamping mechanism 204 is reset, the output end of the telescopic component 245 extends out. Under its drive, the clamping ring 242 can move upward along the guide groove 243 guided by the guide wheel 244. Since the telescopic component 245 is rotatably connected to the sleeve 241 and the clamping ring 242, it can also drive the guide wheel 244 to move into the horizontal section of the guide groove 243. At this time, the upper part of the clamping ring 242 tilts away from the second fixture 209, so that the product can be released from the clamping ring 242.

[0139] When the power supply mechanism 205 is reset, the probe plate 253 moves upward first, and then moves away from the second fixture 209. The first base plate 202 and the second base plate 208 can move away from each other under the drive of their respective corresponding Y-axis linear modules. Based on this, the two base plates drive the first fixture 203 and the second fixture 209 to move away from each other, thereby enabling the MPO plug on the MPO fixture 8 to be pulled out from the optical module on the outer bracket 9.

[0140] The conveying mechanism 5 uses the first gripper assembly 503 to grab the outer support 9 and transport it back to the positioning section 103 of the feeding flow line module 1. The feeding flow line module 1 then operates, sending the coupled product to the receiving section 104 and simultaneously conveying the outer support 9 from the discharge section 102 back to the positioning section 103, where it is grabbed by the first gripper assembly 503. Subsequently, the conveying mechanism 5 uses the second gripper assembly 505 to grab the qualified MPO fixture 8 and send it together to the fixture module 2.

[0141] Furthermore, there are two sets of MPO clamps 8 that hold MPO plugs. The two sets of MPO clamps 8 can be used interchangeably. When the transport mechanism 5 arrives at the fixture module 2, the outer support 9 is first placed on the first fixture 203. While the clamping mechanism 204 and the power supply mechanism 205 work in sequence, the empty second gripper assembly 505 picks up the MPO clamp 8 that has been used on the second fixture 209. Then the support plate 504 rotates 180 degrees and places the qualified MPO clamp 8 that has been picked up in advance by the second gripper assembly 505 on the second fixture 209.

[0142] During the positioning operation of the MPO fixture 8 on the second fixture 209, and the subsequent coupling of the FA and the optical module, the transport mechanism 5 first transports the used MPO fixture 8 to the cleaning module 6, and then to the testing module 7. After passing the test, the MPO fixture 8 is temporarily stored on the support 702 of the testing module 7, waiting for the next gripping; if the test fails, the transport mechanism 5 transports the MPO fixture 8 back to the cleaning module 6 until the MPO plug end face is cleaned and passes the test, and then it is temporarily stored on the support 702.

[0143] In summary, this invention proposes an FA coupling device and its coupling method. The coupling device enables automatic loading and unloading of optical modules and FAs, automatic cleaning, wiping, detection, and plugging / unplugging of MPO fiber optic patch cord end faces, reducing reliance on personnel, simplifying loading and unloading, and reducing reliance on operator skills. The coupling method improves coupling efficiency, enhances production quality stability and yield, and reduces production costs.

S3. After the MPO fixture is placed on the second fixture, the first fixture and the second fixture are brought closer together until the MPO plug is inserted into the optical module. Then the coupling module and the dispensing vision module work together to complete the coupling between the FA and the optical module. After S4 and FA are coupled with the optical module, the coupling module, clamping mechanism and power supply mechanism are reset, the MPO plug is pulled out, the conveying mechanism puts the outer bracket carrying the coupled product back into the feeding flow line module, the feeding flow line module unloads the product and provides the outer bracket carrying the product to be coupled.

9. The coupling method of the FA coupling device according to claim 8, characterized in that, There are two sets of MPO clamps that hold the MPO plug. When replacing them in step S2: One of the second gripper components of the conveying mechanism first grabs the MPO fixture that has completed the MPO plug end face inspection, then the other second gripper component picks up the used MPO fixture from the second fixture, and finally places the MPO fixture that has completed the MPO plug end face inspection on the second fixture. During the coupling process between the FA and the optical module, the handling mechanism sequentially transports the used MPO fixture to the cleaning module and the testing module for end-face cleaning and testing, respectively.
