Description

Technical Field

[0001] This invention relates to the field of optical coupling devices, and more specifically, to a fast optical coupling device and method for an optical fiber collimator. Background Technology

[0002] Fiber optic collimators are a crucial component of passive optical communication devices. Their function is to convert the transmitted light beam in an optical fiber into a collimated beam (parallel light), or to couple an external parallel beam into the optical fiber. During the manufacturing process of fiber optic collimators, the coaxiality between the fiber optic connector and the collimator lens assembly plays a decisive role in optical coupling efficiency. To ensure low-loss transmission of optical signals, the fiber and collimator must be aligned with extremely high precision (i.e., "light alignment"), and reliably fixed after alignment.

[0003] When applying adhesive for fixation after optical alignment, existing automated equipment often struggles to control adhesive distribution. During the mating connection between the fiber and the collimator, uneven adhesive distribution can lead to internal air bubbles or adhesive overflow contaminating the end face. Furthermore, the lack of an effective lubrication mechanism before curing causes friction during mating, potentially disrupting the optimized alignment and affecting coupling efficiency. To address these issues, we propose a rapid optical alignment coupling device and method for fiber optic collimators. Summary of the Invention

[0004] This invention provides a fast optical coupling device and method for fiber optic collimators, solving the technical problem in related technologies where the adhesive lacks an effective lubrication mechanism before curing, leading to friction during the insertion process, which in turn destroys the adjusted optimal optical alignment position and affects coupling efficiency.

[0005] The first aspect of the present invention provides a fast optical coupling device for an optical fiber collimator, comprising:

[0006] For the optical coupler, the optical coupling area of ​​the optical coupler is equipped with corresponding fiber calibration modules and collimator calibration modules, which are used to adjust the fiber head and collimator to achieve coupling between the two, as well as an intelligent dispensing module.

[0007] The collimator calibration module includes two tangent collimator rotating columns, a collimator base, a light-collecting camera, and a power supply module;

[0008] Two collimator rotating posts are rotatably mounted on the upper surface of the collimator base along the centerline direction, and the top of the collimator rotating posts protrudes beyond the upper surface of the collimator base.

[0009] The power supply module is connected to the two collimator rotors and is used to control the two collimator rotors to perform reciprocating rotation in the same direction and synchronously.

[0010] The collimator is placed in the gap above the two collimator rotating columns, and the light-capturing camera is set at the light source illumination end of the collimator to capture the light source data emitted by the collimator in real time.

[0011] After the optical fiber calibration module and collimator calibration module complete the spatial alignment of the optical fiber and collimator, a drop of glue is automatically applied to the contact end of the optical fiber and collimator by the glue dispensing module.

[0012] During the insertion process between the optical fiber and the collimator, the reciprocating rotation of the collimator's rotating post allows the adhesive to enter the collimator evenly, thus providing a lubricating effect.

[0013] The light-capturing camera continuously captures light source data during the dispensing and interlocking process until the light source data meets the preset conditions, triggering the adhesive curing process.

[0014] Furthermore, the fiber optic calibration module also includes a fiber optic end adjustment base and a fiber optic base, with the fiber optic base mounted on the fiber optic end adjustment base for adjusting the fiber optic base.

[0015] Furthermore, an optical fiber pressure plate is rotatably mounted on the upper wall of the optical fiber holder, and the optical fiber pressure plate is located at one end near the collimator holder. The optical fiber is pressed and fixed by the optical fiber pressure plate. A curing lamp cover is provided between the optical fiber calibration module and the collimator calibration module for curing the adhesive after the insertion is completed.

[0016] Furthermore, the collimator calibration module also includes a collimator end adjustment seat, on which the collimator seat is set for adjusting the collimator seat. The upper wall of the collimator seat is rotatably equipped with a collimator pressure plate for pressing the collimator between two collimator rotating columns.

[0017] Furthermore, the power supply module includes a power box fixed to the side wall of the collimator seat. Inside the power box, a take-up motor assembly is fixedly installed. At the end of the take-up motor assembly, a winding reel is provided, and a drive main wire is wound on the winding reel.

[0018] Furthermore, the upper wall of the collimator base is provided with a light-passing groove, and the light-passing groove is located at the end of the two collimator rotating columns. The light source emitted by the collimator passes through the light-passing groove, and the light-passing groove does not affect the illumination of the light source.

[0019] Furthermore, the power supply module also includes a limit box, inside which a reciprocating rack is slidably arranged. Two gear discs are arranged above the reciprocating rack, and the two gear discs are fixedly connected to two collimator rotating columns respectively. Both gear discs mesh with the reciprocating rack.

[0020] Furthermore, a sliding column is inserted inside the reciprocating rack, and springs are sleeved on the outside of the sliding column at both ends of the reciprocating rack. The reciprocating rack is fixedly connected to the end of the transmission main wire, and the reciprocating rack is pulled to slide back and forth along the sliding column by the transmission main wire.

[0021] Furthermore, a light-catching plate is directly installed between the light-catching camera and the collimator light source to capture the light source point of the collimator. The light source point can be displayed on the back for the light-catching camera to capture, thus avoiding direct illumination of the light-catching camera by the light source.

[0022] A second aspect of the present invention provides a fast optical coupling method for a fast optical coupling device of an optical fiber collimator, comprising the following steps:

[0023] S1. Install the fiber optic head and collimator into the fiber optic calibration module and collimator calibration module respectively;

[0024] S2. Adjust the spatial position of the fiber head and the collimator through the fiber calibration module and the collimator calibration module until the light source data captured by the light-collecting camera meets the alignment requirements.

[0025] S3. A drop of glue is automatically applied to the contact end between the optical fiber and the collimator via the glue dispensing module;

[0026] S4. Drive the collimator rotating column to rotate back and forth, so that the collimator can be inserted with the fiber head during the rotation, and at the same time, the glue can be evenly entered into the collimator.

[0027] S5. During the dispensing and insertion process, the light source data is continuously captured by the light-capturing camera. Once the light source data meets the preset conditions, the glue curing process is triggered.

[0028] The beneficial effects of this invention are as follows:

[0029] This invention achieves multi-dimensional spatial adjustment of the optical fiber and collimator by setting up corresponding optical fiber calibration modules and collimator calibration modules. With the real-time feedback from the light-harvesting camera, the optimal coupling point can be found quickly, which significantly improves the light-harvesting speed and accuracy.

[0030] Innovatively, two collimator rotating posts are set on the collimator mount that can rotate synchronously back and forth. During the insertion process between the optical fiber and the collimator, the rotation of the rotating posts causes the collimator to generate a slight rotational motion. This motion, combined with the adhesive dripped by the dispensing module, allows the adhesive to penetrate evenly into the gaps inside the collimator, while effectively reducing insertion friction and providing lubrication. This prevents the aligned optical fiber from shifting due to excessive friction, thus ensuring the stability of the coupling. Attached Figure Description

[0041] Example 1

[0042] like Figures 1-8 As shown, a fast optical coupling device for an optical fiber collimator includes:

[0043] For the optical coupler 11, the optical coupling area of ​​the optical coupler 11 is respectively provided with a corresponding fiber calibration module and a collimator calibration module, which are used to adjust the fiber head and the collimator to achieve the coupling of the two, as well as an intelligent dispensing module 17.

[0044] The collimator calibration module includes two tangent collimator rotating columns 28, a collimator seat 15, a light-collecting camera 24, and a power supply module;

[0045] Two collimator rotating posts 28 are rotatably disposed on the upper surface of the collimator base 15 along the centerline direction of the collimator base 15, and the top height of the collimator rotating posts 28 protrudes beyond the upper surface of the collimator base 15.

[0046] The power supply module is connected to the two collimator rotating columns 28 and is used to control the two collimator rotating columns 28 to perform reciprocating rotation in the same direction and synchronously.

[0047] The collimator is placed in the gap above the two collimator rotating columns 28, and the light-capturing camera 24 is set at the light source illumination end of the collimator to capture the light source data emitted by the collimator in real time.

[0048] After the optical fiber calibration module and collimator calibration module complete the spatial alignment of the optical fiber and collimator, a drop of glue is automatically applied to the contact end of the optical fiber and collimator by the glue dispensing module 17.

[0049] During the insertion process between the optical fiber and the collimator, the reciprocating rotation of the collimator rotating post 28 allows the adhesive to enter the collimator evenly, thus providing a lubricating effect.

[0050] The light-capturing camera 24 continuously captures light source data during the dispensing and interlocking process until the light source data meets the preset conditions, triggering the adhesive curing process.

[0051] The fiber optic calibration module also includes a fiber optic end adjustment seat 12 and a fiber optic seat 14. The fiber optic seat 14 is mounted on the fiber optic end adjustment seat 12 and is used to adjust the fiber optic seat 14.

[0052] The upper wall of the fiber optic base 14 is rotatably equipped with a fiber optic pressure plate 18, which is located at one end near the collimator base 15. The fiber optic plate 18 is used to press and fix the fiber optic cable. A curing lamp cover 16 is provided between the fiber optic calibration module and the collimator calibration module for curing the adhesive after the connection is completed.

[0053] The collimator calibration module also includes a collimator end adjustment seat 13, and a collimator seat 15 is set on the collimator end adjustment seat 13 for adjusting the collimator seat 15. A collimator pressure plate 21 is rotatably set on the upper wall of the collimator seat 15 for pressing the collimator between two collimator rotating columns 28.

[0054] The power supply module includes a power box 25 fixed to the side wall of the collimator seat 15. A take-up motor assembly 31 is fixedly installed inside the power box 25. A winding reel is provided at the end of the winding motor assembly 31, and a drive main wire 26 is wound on the winding reel.

[0055] The upper wall of the collimator base 15 is also provided with a light-passing groove 27, and the light-passing groove 27 is located at the end of the two collimator rotating posts 28. The light source emitted by the collimator passes through the light-passing groove 27, and the light-passing groove 27 does not affect the illumination of the light source.

[0056] The power supply module also includes a limit box 29, inside which a reciprocating rack 33 is slidably arranged. Two gear discs 34 are arranged above the reciprocating rack 33, and the two gear discs 34 are fixedly connected to two collimator rotating columns 28 respectively. Both gear discs 34 mesh with the reciprocating rack 33.

[0057] The reciprocating rack 33 has a sliding column 35 inside, and springs 36 are sleeved on the outside of the sliding column 35 at both ends of the reciprocating rack 33. The reciprocating rack 33 is fixedly connected to the end of the transmission main wire 26. The reciprocating rack 33 is pulled to slide back and forth along the sliding column 35 by the transmission main wire 26.

[0058] A light-catching plate 23 is directly mounted on the light-catching camera 24 and the collimator light source to capture the light source point of the collimator. The light source point can be displayed on the back for capture by the light-catching camera 24, thus avoiding direct illumination of the light-catching camera 24 by the light source.

[0059] Its core working principle lies in the synergistic effect of three mechanisms: precise mechanical adjustment, dynamic lubrication coupling, and optical closed-loop feedback, to achieve high-efficiency, high-precision, and highly automated optical coupling between the optical fiber and the collimator. The entire workflow can be divided into four main stages: spatial alignment stage, adhesive lubrication stage, dynamic coupling stage, and curing determination stage.

[0060] Spatial alignment stage: Establishing the initial optical path

[0061] During this stage, the device adjusts the fiber head and collimator to a preliminary alignment state through the fiber calibration module and collimator calibration module, respectively.

[0062] Fiber optic end adjustment: The operator or system controls the fiber optic end adjustment seat 12, which drives the fiber optic seat 14 on it to perform precise six-degree-of-freedom (X, Y, Z, Pitch, Yaw, Roll) displacement. The fiber optic clamping plate 18 presses and fixes the fiber optic end, ensuring its stable position.

[0063] Collimator end adjustment: Simultaneously, the collimator end adjustment seat 13 drives the collimator seat 15 to perform multi-dimensional adjustments. The collimator is placed in the gap above the two tangent collimator rotating columns 28, and is provided with a slight preload by the collimator pressure plate 21 to maintain good contact with the surfaces of the two rotating columns.

[0064] Optical coarse alignment: During the adjustment process, the light beam emitted from the collimator's light source passes through the light-passing groove 27 and illuminates the light-collecting plate 23. The light-collecting camera 24 captures the position, shape, and intensity distribution of the light spot in real time. The system analyzes the centroid coordinates of the light spot... ) and total luminous intensity The guide adjustment seat performs closed-loop control until the light spot is located in the center area of ​​the light-collecting plate 23 and the light intensity reaches the preset threshold, thus completing the coarse alignment.

[0065] In the dispensing lubrication stage: introducing a coupling medium.

[0066] When the spatial alignment accuracy meets the requirements (e.g., spot centroid offset), After that, the system enters the dispensing stage.

[0067] Automatic dispensing: The intelligent dispensing module 17 is activated to precisely dispense a drop of adhesive (e.g., volume V≈0.5μL) between the contact surfaces of the fiber optic head and the collimator tail.

[0068] Lubrication preparation: At this stage, the optical fiber and collimator are not yet fully inserted. The applied adhesive acts as a crucial "liquid bearing," providing lubrication for the subsequent insertion process and preventing damage to the precision optical end face from hard contact.

[0069] Dynamic coupling stage: Achieving precise alignment and uniform adhesive application

[0070] This stage is the core part. The reciprocating rotation of the collimator column 28 enables precise rotational drive of the collimator, while also promoting uniform glue filling.

[0071] Power transmission and motion conversion: The power supply module is activated. The take-up motor assembly 31 drives the winding reel to rotate, and through the take-up and untake-up transmission main wire 26, it pulls the reciprocating rack 33 to make linear reciprocating motion along the slide column 35 within the limit box 29.

[0072] Let the displacement of the reciprocating rack 33 be... ,in For amplitude, For frequency.

[0073] The reciprocating rack 33 simultaneously meshes with two gear discs 34, converting linear motion into synchronous reciprocating rotation of the two collimator columns 28 in the same direction. Its rotation angle... With rack displacement The relationship is:

[0074] ;

[0075] in The pitch circle radius of the gear disc 34 is given.

[0076] Dynamic alignment and adhesive penetration: Driven by the two collimator rotating columns 28, the collimator itself undergoes a slight reciprocating rotation. This rotational motion produces two key effects:

[0077] Active alignment: As the collimator rotates, its internal ferrule will automatically find the path of least resistance with the fiber optic head due to mechanical inertia and the hydrodynamic effect of the adhesive, achieving sub-micron level precision automatic alignment.

[0078] Uniform glue penetration: The shear force generated by the rotational motion causes the glue to flow within the tiny gaps inside the collimator. The glue filling rate can be approximated by the Navier-Stokes equations, and its radial flow velocity... Collimator rotation speed and gap Proportional:

[0079] ;

[0080] in The dynamic viscosity of the adhesive. The average radius of rotation is [value missing]. This dynamic filling method ensures that the adhesive layer is bubble-free and of uniform thickness, thus guaranteeing the final optical performance.

[0081] Curing determination stage: Closed-loop curing based on optical properties

[0082] Throughout the dynamic coupling process, the light-catching camera 24 continuously monitors the light source data emitted from the collimator.

[0083] Performance monitoring: The system calculates coupling efficiency in real time. It is defined as the current received light intensity. With the theoretical maximum coupling intensity The ratio:

[0084] ;

[0085] Curing Trigger: As the adhesive penetrates evenly and dynamic alignment proceeds, the coupling efficiency gradually increases and tends to stabilize. The system sets a preset condition, for example:

[0086] Condition 1: Coupling efficiency ≥95%.

[0087] Condition 2: Coupling efficiency in continuous time Such as the variance of fluctuation within 5 seconds <0.1%.

[0088] Automatic curing: When the above conditions are met simultaneously, the system determines that the coupling has reached the optimal state. At this time, the ultraviolet lamp in the curing lamp cover 16 located between the fiber optic calibration module and the collimator calibration module is automatically activated to quickly cure the adhesive and permanently lock this optimal optical state.

[0089] Process analysis of each module:

[0090] For the optical coupler module 11: it serves as the base and integration platform for the entire device, carrying and coordinating the operation of the fiber optic calibration module, collimator calibration module, and dispensing module 17.

[0091] Fiber optic calibration module:

[0092] Composition: Fiber optic end adjustment seat 12, fiber optic seat 14, fiber optic pressure plate 18.

[0093] Process: The fiber optic seat 14 is precisely positioned by adjusting the fiber optic end 12 → the fiber optic pressure plate 18 presses the fiber to complete the spatial attitude locking of the fiber optic end.

[0094] Collimator calibration module:

[0095] Composition: collimator end adjustment seat 13, collimator seat 15, collimator pressure plate 21, two collimator rotating columns 28, power supply module, light-catching camera 24, light-catching plate 23.

[0096] Process: The collimator is placed on the collimator rotating column 28 → the collimator pressure plate 21 is pre-tightened → the collimator end adjustment seat 13 performs spatial coarse alignment → the power supply module drives the collimator rotating column 28 to reciprocate, achieving dynamic precision alignment and lubrication.

[0097] Power supply module:

[0098] Composition: Power box 25, take-up motor assembly 31, main drive wire 26, limit box 29, reciprocating rack 33, gear plate 34, slide column 35, spring 36.

[0099] Process: The take-up motor assembly 31 rotates → the winding reel takes up / unwinds the drive main wire 26 → the drive main wire 26 pulls the reciprocating rack 33 to slide along the slide column 35 against the force of the spring 36 → the reciprocating rack 33 drives the two gear discs 34 to rotate synchronously → the gear discs 34 drive the two collimator rotating columns 28 to reciprocate in the same direction.

[0100] Intelligent dispensing module 17:

[0101] Process: After coarse alignment is completed, adhesive is precisely applied to the contact end between the optical fiber and the collimator under the control of the control system.

[0102] Optical inspection and curing module:

[0103] Composition: light-collecting plate 23, light-collecting camera 24, curing lamp cover 16.

[0104] Process: The collimator emits light onto the light-collecting plate 23 to form a light spot → The light-collecting camera 24 collects the light spot data in real time → The system analyzes the coupling efficiency → When the data meets the preset conditions, the curing lamp in the curing lamp cover 16 is triggered to cure the adhesive.

[0105] Significantly improved coupling efficiency and consistency: The collimator achieves synchronous reciprocating rotation in the same direction through two tangent collimator rotating posts 28, providing a dynamic self-alignment mechanism during insertion and effectively avoiding coupling loss caused by mechanical tolerances and form errors during static alignment. Combined with real-time feedback from the light-harvesting camera 24, curing is only triggered when optical performance reaches its optimal level, ensuring that each product achieves the highest and most consistent coupling efficiency.

[0106] Achieving damage-free precision assembly: Before the optical fiber is inserted into the collimator, adhesive is automatically applied by the dispensing module 17, which acts as a lubricant and buffer medium. The reciprocating rotation of the collimator driven by the collimator rotating column 28 ensures that the adhesive is evenly distributed into the contact gap, greatly reducing insertion friction and avoiding fatal damage such as scratches and chipping caused by hard extrusion on the optical end face, thus improving the yield rate.

[0107] Example 2
