Description

Technical Field

[0001] This invention relates to the field of optical communication technology, and in particular to a manufacturing system for a 90-degree fiber array microperforated plate for optical communication. Background Technology

[0002] A 90-degree fiber optic array is an optical component with fibers arranged at a 90-degree angle, widely used in optical communication, optical sensing, and fiber optic coupling. By arranging the fibers at 90-degree angles, it optimizes the spatial layout of the fibers, improving transmission efficiency and coupling effect while reducing signal interference. This technology is commonly used in wavelength division multiplexing (WDM) systems, laser arrays, and high-density fiber optic connections. Precise control of fiber splicing, material selection, and array density is required during design to ensure high performance and low loss. With increasing demands for integration and miniaturization, 90-degree fiber optic arrays will play a greater role in future optoelectronic technologies, particularly in high-speed, long-distance communication and high-power applications.

[0003] Our experimental team has long been reviewing and studying a large amount of relevant documentation on fiber optic array technology. Utilizing relevant resources and conducting numerous experiments, we discovered existing technologies such as those disclosed in CN112540424B, CN111766660B, and CN115980929B. One such technology discloses a high-precision fiber optic array and its fabrication method, which includes the following steps: preparing a substrate, a cover plate, and several fiber segments; and using a wet etching process to fabricate interconnected V-grooves on the substrate. The process involves: removing the coating from one end of each fiber segment to expose the cladding; placing the cladding at one end of each fiber segment into a V-groove on the substrate, while simultaneously extending the other end of each fiber segment outward from the groove; pressing a cover plate onto the upper surface of the substrate from top to bottom; injecting a first UV-curable adhesive between the cladding of each fiber segment and the two inclined surfaces of the corresponding V-groove, and the lower surface of the cover plate, and curing the first UV-curable adhesive by UV lamp irradiation; injecting a second UV-curable adhesive into the groove and curing the second UV-curable adhesive by UV lamp irradiation; and polishing the assembled fiber array assembly.

[0004] This invention was developed to address common problems in the field, such as damage caused by material stress and thermal expansion, shortage of 90-degree array fiber optic boards, inability to continuously and stably etch fiber optic slots, and difficulty in ensuring the processing accuracy and consistency of fiber optic slots. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings existing in the field by proposing a manufacturing system for a 90-degree fiber array microperforated plate for optical communication.

[0006] To overcome the shortcomings of the prior art, the present invention adopts the following technical solution:

All fiber optic slots are identical and arranged in parallel. The bottom surface of the cover plate can cover the top surface of the base substrate. The top surface of the base substrate is the same plane where the fiber optic slots and locking grooves are located. At the same time, the bottom surface of the cover plate is provided with protrusions that engage and fix with the locking grooves. By fixing the cover plate to the base substrate, the fiber optic cables in the fiber optic slots are limited and fixed, so that the fiber optic cables are arranged by turning at a 90-degree angle.

[0009] A manufacturing system for the 90-degree fiber array microporous plate of claim 1, the manufacturing system comprising a movable fixing module for clamping and fixing a preliminary substrate of the base substrate, a laser module for laser etching the fiber grooves on the top surface of the preliminary substrate, and a preheating module for preheating the preliminary substrate.

[0010] The preliminary substrate and cover plate are made of ceramic powder and resin binder as raw materials. After being shaped by a mold, they are further processed by a thermoforming machine. The top surface of the base substrate made by the thermoforming machine does not have fiber optic grooves. The top surface of the base substrate made by the thermoforming machine is further processed by a laser module to create fiber optic grooves. After the preliminary substrate is etched with fiber optic grooves by the laser module, it becomes the base substrate.

[0011] Furthermore, the movable fixing module includes a belt conveyor, a plurality of flexible silicone rollers fixed at preset intervals on the conveyor belt of the belt conveyor, a base plate welded and fixed to the flexible silicone rollers, and adapter fixing components respectively installed on the base plate.

[0012] The belt conveyor is used to transport the preliminary substrate to the laser etching area of ​​the laser module for operation via a continuous conveyor belt. Each flexible silicone roller is set perpendicular to the horizontal conveying direction of the conveyor belt. The bottom of the flexible silicone roller is fixed to the conveyor belt, while the top of the flexible silicone roller is fixed to the bottom wall of the base plate.

[0013] Furthermore, the adapter fixing assembly includes a first support rod vertically fixed to the base plate, a second support rod vertically fixed to the base plate, a first rotating shaft movably passing through the first support rod via a bearing ring, a second rotating shaft movably passing through the second support rod via a bearing ring, a rotary drive motor fixed to the side wall of the first support rod via a corresponding mounting seat and with its power output shaft fixedly connected to the first rotating shaft, a rotating plate horizontally disposed between the first and second support rods, a reinforcing bracket fixed to the rotating plate, and an adsorption bracket fixed to the reinforcing bracket for adsorbing and fixing the bottom surface of the preliminary substrate.

[0014] Furthermore, the top of the first support rod is provided with a first through-hole, and a bearing ring is fitted onto the first through-hole. The first rotating shaft is fitted onto the inner ring of the bearing ring at the first through-hole, so that the first rotating shaft can rotate and engage with the first through-hole. Similarly, the top of the second support rod is provided with a second through-hole, and a bearing ring is fitted onto the second through-hole. The second rotating shaft is fitted onto the inner ring of the bearing ring at the second through-hole, so that the second rotating shaft can rotate and engage with the second through-hole. Moreover, the first rotating shaft and the second rotating shaft are coaxially arranged. The rotation drive motor drives the rotation of the first rotating shaft to synchronously drive the base plate to rotate synchronously.

[0015] Furthermore, the reinforcing bracket includes two vertical reinforcing rods fixed to the rotating plate and a horizontal reinforcing rod connecting the two vertical reinforcing rods.

[0016] Furthermore, the adsorption support includes two mutually perpendicularly connected unit rods, adsorption nozzles respectively embedded on the surface of the unit rods, several channel cavities respectively disposed in the unit rods, several vent pipes respectively embedded in the channel cavities for sequentially connecting the air extraction holes of the adsorption nozzles, an air pump for generating negative pressure and installed on the rotating plate, and a connecting pipe for connecting the adsorption end of the air pump to the vent pipes, wherein the negative pressure is generated by the air pump.

[0017] Furthermore, the preheating module includes several heating elements uniformly distributed on the outer wall of the unit rod, a temperature sensor for monitoring temperature changes on the surface of the unit rod, and a circuit control board for adjusting the heating power and temperature of the heating elements.

[0018] Each heating element is fixed to the outer surface of the unit rod through a high thermal conductivity adhesive layer, forming a tight fit structure. The heating surface of the heating element can evenly transfer heat to the unit rod. The heating element is connected to the control circuit board through wires. The control circuit board can adjust the heating temperature and heating time of each heating element according to the working needs, thereby achieving precise temperature control of the entire unit rod or a local area. The preheating module is designed to evenly conduct heat to the area around the adsorption nozzle through the unit rod, thereby uniformly heating the initial substrate.

[0019] The beneficial effects achieved by this invention are:

[0020] 1. High-precision fiber optic slot processing was achieved, ensuring the performance stability and consistency of the fiber optic array: By combining a laser module with high-precision laser processing technology, micron-level fiber optic slot etching was performed on the initial substrate to ensure that the size, depth, and shape of the fiber optic slots were highly consistent, thereby improving the coupling efficiency of the optical fiber and the transmission performance of the optical signal, and meeting the requirements of optical communication for high-precision fiber optic arrays.

[0021] 2. Effectively avoids substrate damage or deformation caused by material thermal stress and processing errors: The preheating module uniformly heats the initial substrate, avoiding thermal stress concentration or material cracking caused by local temperature changes during laser processing. At the same time, the flexible silicone roller design ensures that the risk of substrate deformation due to uneven force during transmission is eliminated, thereby significantly improving the reliability and yield of substrate processing.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to its embodiments. It should be noted that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this invention. Other systems, methods, and / or features of this embodiment will become apparent to those skilled in the art after reviewing the following detailed description. Furthermore, the terminology used to describe positional relationships in the accompanying drawings is for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0030] Example 1: Combined with Appendix Figure 1 This embodiment constructs a manufacturing system for a 90-degree fiber array microperforated plate for optical communication. The 90-degree fiber array microperforated plate includes a base substrate and a cover plate that covers the base substrate. The base substrate includes a first base block, a second base block that is perpendicular to the first base block, and an arc-shaped block that is connected at one end to the first base block and at the other end to the second base block. The first base block, the arc-shaped block, and the second base block are integrally formed.

[0031] The top surface of the base plate is provided with a number of fiber optic slots and at least four locking grooves. Each fiber optic slot is used to fix one fiber optic cable. All fiber optic slots are identical to each other and arranged in parallel.

[0032] The bottom surface of the cover plate can cover the top surface of the base substrate. The top surface of the base substrate is the same plane where the fiber optic groove and the locking groove are located. At the same time, the bottom surface of the cover plate is provided with a protrusion that engages and fixes with the locking groove. By fixing the cover plate to the base substrate, the fiber optic cable in the fiber optic groove is limited and fixed, so that the fiber optic cable is arranged by turning at a 90-degree angle.

[0033] The synergistic design of the arc-shaped block and the fiber optic slot allows the fiber to bend smoothly at a large arc, thus avoiding the problem of excessive bending and breakage of the fiber when subjected to external forces.

[0034] Example 2: Combined with Appendix Figure 2 Appendix Figure 3 and attached Figure 4 This embodiment constructs a manufacturing system for a 90-degree fiber array microperforated plate for optical communication. The manufacturing system includes a movable fixing module for clamping and fixing a preliminary substrate of the base substrate, a laser module for laser etching the fiber grooves on the top surface of the preliminary substrate, and a preheating module for preheating the preliminary substrate.

[0035] The preliminary substrate and cover plate are made of ceramic powder and resin binder as raw materials. After being shaped by a mold, they are further processed by a thermoforming machine. The top surface of the base substrate made by the thermoforming machine does not have fiber optic grooves. The top surface of the base substrate made by the thermoforming machine is further processed by a laser module to create fiber optic grooves. After the preliminary substrate is etched with fiber optic grooves by the laser module, it becomes the base substrate.

[0036] The movable fixing module includes a belt conveyor, several flexible silicone rollers fixed at preset intervals on the conveyor belt of the belt conveyor, a base plate welded and fixed to the flexible silicone rollers, and adapter fixing components respectively installed on the base plate.

[0037] The belt conveyor is used to transport the initial substrate to the laser etching area of ​​the laser module via a continuous conveyor belt. Each flexible silicone roller is set perpendicular to the horizontal conveying direction of the conveyor belt. The bottom of the flexible silicone roller is fixed to the conveyor belt, while the top of the flexible silicone roller is fixed to the bottom wall of the base plate. When the conveyor belt passes through the arc-shaped bending areas on both sides, the flexible silicone roller can fully support the base plate. Since the flexible silicone roller is set perpendicular to the horizontal conveying direction of the conveyor belt, the flexible silicone roller can effectively counteract the shearing force generated during the bending process of the conveyor belt, effectively preventing the substrate from being damaged or cracked due to uneven force when passing through the bending area.

[0038] The movable fixing module of this invention, through the support of flexible silicone rollers, ensures that the base plate can pass stably and smoothly through the bending area of ​​the belt conveyor, thereby realizing the continuous clamping and transportation of the preliminary substrate by the adapter fixing component. When the substrate passes through the vertical support of the flexible silicone rollers, not only is deformation or damage caused by bending of the base plate avoided, but the stability of the base plate is also guaranteed. This ensures that the adapter fixing component can efficiently and accurately transport the preliminary substrate to the laser module for laser etching of the fiber optic groove throughout the entire processing flow, thereby improving the overall processing accuracy and efficiency of the system.

[0039] The adapter fixing assembly includes a first support rod vertically fixed to the base plate, a second support rod vertically fixed to the base plate, a first rotating shaft movably passing through the first support rod via a bearing ring, a second rotating shaft movably passing through the second support rod via a bearing ring, a rotary drive motor fixed to the side wall of the first support rod via a corresponding mounting seat and with its power output shaft fixedly connected to the first rotating shaft, a rotating plate horizontally disposed between the first and second support rods, a reinforcing bracket fixed to the rotating plate, and an adsorption bracket fixed to the reinforcing bracket for adsorbing and fixing the bottom surface of the preliminary substrate.

[0040] The top of the first support rod is provided with a first through-hole, and a bearing ring is fitted onto the first through-hole. The first rotating shaft is fitted onto the inner ring of the bearing ring at the first through-hole, so that the first rotating shaft can rotate and engage with the first through-hole. Similarly, the top of the second support rod is provided with a second through-hole, and a bearing ring is fitted onto the second through-hole. The second rotating shaft is fitted onto the inner ring of the bearing ring at the second through-hole, so that the second rotating shaft can rotate and engage with the second through-hole. The first rotating shaft and the second rotating shaft are coaxially arranged.

[0041] The rotary drive motor drives the base plate to rotate synchronously by driving the rotation of the first rotating shaft. The reinforcing bracket includes two vertical reinforcing rods fixed to the rotating plate and a horizontal reinforcing rod connected between the two vertical reinforcing rods.

[0042] The adsorption support includes two perpendicularly connected unit rods, adsorption nozzles embedded in the surface of the unit rods, several channel cavities respectively disposed within the unit rods, several vent pipes respectively embedded in the channel cavities for sequentially connecting the air extraction holes of the adsorption nozzles, an air pump installed on the rotating plate for generating negative pressure, and a connecting pipe for connecting the adsorption end of the air pump to the vent pipes. The negative pressure is generated by the air pump, causing each adsorption nozzle to generate adsorption force to adsorb and fix the bottom surface of the preliminary substrate. The unit rods are fixed to the reinforcing support by bolts. The connecting pipes can be selected by those skilled in the art based on actual needs, either as multiple pipes connecting all vent pipes simultaneously or as a single pipe connecting each vent pipe separately, without limitation.

[0043] The preheating module includes several heating elements uniformly distributed on the outer wall of the unit rod, a temperature sensor for monitoring temperature changes on the surface of the unit rod, and a circuit control board for adjusting the heating power and temperature of the heating elements. Each heating element is fixed to the outer surface of the unit rod by a high thermal conductivity adhesive layer, forming a tightly fitted structure. The heating surface of the heating element can uniformly transfer heat to the unit rod. The heating elements are connected to the control circuit board through wires. The control circuit board can adjust the heating temperature and heating time of each heating element according to the working needs, thereby achieving precise temperature control of the entire unit rod or a local area. The design of the preheating module is to uniformly conduct heat to the area around the suction nozzle through the unit rod, thereby uniformly heating the preliminary substrate and avoiding thermal stress concentration or material cracking caused by local overheating or overcooling during laser etching, thus improving the etching efficiency of the fiber groove of the preliminary substrate.

[0044] The laser module is implemented through a laser etching machine located adjacent to the belt conveyor, with the laser head of the laser etching machine positioned above the belt conveyor. The laser etching machine sequentially etches the preliminary substrate passing below it. Based on existing high-precision laser processing technology, the laser etching machine uses a built-in F-Theta focusing lens to precisely focus a high-energy laser beam onto the top surface of the preliminary substrate, performing micron-level precision etching on the fiber optic grooves. The laser etching machine has the ability to adjust the laser power, pulse frequency, and scanning speed in real time to adapt to the etching depth requirements of different positions on the preliminary substrate. It also combines industrial vision positioning technology to dynamically detect the position and angle of the preliminary substrate, ensuring precise processing of different areas on the top surface of the preliminary substrate by the laser beam. This achieves a high degree of consistency in the size, depth, and shape of the fiber optic grooves, guaranteeing high precision, high efficiency, and stability of the etching operation.

[0045] Meanwhile, after fixing the initial substrate, the adaptive clamping assembly drives the first and second rotating axes through a rotary drive motor to achieve precise rotation operation, which can gradually move different areas of the top surface of the initial substrate to below the processing area of ​​the laser etching machine, thereby realizing continuous etching processing of the entire top surface of the substrate, effectively solving the limitation of the laser etching machine that can only perform etching operations on planar areas.

[0046] The rotation of the adaptive clamping component is achieved by a precise control system of the rotary drive motor. The adaptive clamping component can dynamically adjust the rotation angle and speed of the substrate according to the processing path and processing requirements of the laser etching machine, ensuring a smooth and deviation-free transition between processing areas, thereby guaranteeing the processing accuracy and consistency of the fiber groove on the top surface of the initial substrate.

[0047] The manufacturing system of this invention, through modular design and collaborative working mechanism, uses a preheating module to prevent thermal stress from causing damage to the initial substrate through precise temperature management, an active fixing module to ensure the stability of the base plate during transmission through a flexible silicone roller, and an adapter fixing component to achieve continuous etching of the entire area of ​​the initial substrate by rotating the substrate, thus realizing the efficient production of 90-degree fiber array microporous plates.

[0048] Example 3: Combined with Appendix Figure 2 Appendix Figure 3 and attached Figure 4 In addition to the content of the above embodiments, the specific operation steps of the manufacturing system include:

[0049] S1: Ceramic powder and resin binder are mixed in a preset ratio to form a uniform composite material. The composite material is shaped into a preliminary substrate and a cover plate by different molds. Then, the composite material with the preliminary substrate and cover plate shaped is placed in a thermoforming machine for thermoforming to obtain the preliminary substrate and cover plate.

[0050] S2: At the beginning of the belt conveyor, the preliminary substrate is fixed in sequence on the adsorption bracket with the matching fixing component. The adsorption bracket is driven by a negative pressure motor to achieve stable adsorption of the preliminary substrate. The preliminary substrate is then conveyed to the bottom of the laser etching machine through the movable fixing module.

[0051] S3: Before reaching the laser module, the preliminary substrate is preheated by the preheating module. The heat generated by the heating element is evenly conducted to the preliminary substrate, so that the preliminary substrate reaches a uniform preheating temperature. This avoids the problem of material thermal stress concentration or cracking caused by local overcooling or overheating during laser etching, thereby improving the stability of laser processing.

[0052] S4: The laser etching machine precisely focuses a high-energy laser beam onto the top surface of the preliminary substrate. The adapter fixing component uses a rotary drive motor to move different areas of the top surface of the preliminary substrate sequentially to the bottom of the laser etching machine, ensuring the consistency of the size, depth and shape of the fiber optic grooves on the top surface of the preliminary substrate.

[0053] S5: After the fiber optic groove etching is completed, the base substrate is conveyed to the end of the belt conveyor. The negative pressure motor at the end of the conveyor stops working and releases the processed base substrate. Then, the adsorption bracket returns to the beginning of the conveyor via the belt conveyor. The negative pressure motor restarts and adsorbs and fixes the new preliminary substrate to enter the next round of processing.

[0054] The manufacturing system of this invention is based on modular design and fully automated process, and has significant advantages in high-efficiency production, high-precision processing and high-stability operation. It can significantly improve the processing quality and production efficiency of 90-degree fiber array micro-perforated plates, while greatly reducing manual intervention and scrap rate, thus meeting the manufacturing needs of modern optical communication equipment.
