DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is further described in detail in combination with its embodiments below; it should be pointed out that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present case. For those skilled in the art, after reviewing the following detailed description, other systems, methods and / or features of this embodiment will become apparent. And the terms describing the positional relationship in the accompanying drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0030] Embodiment 1: Combining with the attached Figure 1 This embodiment constructs a 90-degree fiber array microwell plate for optical communication, wherein the 90-degree fiber array microwell plate includes a base substrate and a cover plate covering the base substrate, wherein the base substrate includes a first base block, a second base block vertically arranged with the first base block, and an arc block with one end connected to the first base block and the other end connected to the second base block, wherein the first base block, the arc block and the second base block are integrated.

[0031] A plurality of optical fiber grooves and at least four engaging grooves are arranged on the top surface of the base substrate, each optical fiber groove is used to fix an optical fiber, and all the optical fiber grooves 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, and the top surface of the base substrate is the same plane as the optical fiber groove and the engaging groove. At the same time, the bottom surface of the cover plate is provided with a protrusion that is engaged and fixed with the engaging groove. The optical fiber in the optical fiber groove is limited and fixed by fixing the cover plate and the base substrate, so that the optical fiber can be arranged by turning at a 90-degree angle.

[0033] The design of the arc block and the optical fiber groove works together to enable the optical fiber to be bent smoothly at a larger arc, thereby avoiding the problem of excessive bending and breakage of the optical fiber when subjected to external forces.

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

[0035] Among them, the preliminary substrate and cover plate are made of a mixture of ceramic powder and resin binder as raw materials. After being shaped by a mold, they are further processed and formed by a thermoplastic molding machine. The top surface of the base substrate made by the thermoplastic molding machine does not have an optical fiber groove. The top surface of the base substrate made by the thermoplastic molding machine is further made with an optical fiber groove by a laser module. The preliminary substrate becomes a base substrate after being etched with an optical fiber groove by the laser module.

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

[0037] The belt conveyor is used to transport the preliminary substrate to the laser etching area where the laser module operates through a continuous conveyor belt. Each flexible silicone stick is arranged perpendicular to the horizontal conveying direction of the conveyor belt. The bottom of the flexible silicone stick is fixed to the conveyor belt, and the top of the flexible silicone stick is fixed to the bottom wall of the base plate. When the conveyor belt passes through the arc bending areas on both sides, the flexible silicone stick can fully support the base plate. Since the flexible silicone stick is arranged perpendicular to the horizontal conveying direction of the conveyor belt, the flexible silicone stick can effectively offset the shear force generated during the bending process of the conveyor belt, and effectively prevent the substrate from being damaged or cracked due to uneven force when passing through the bending area.

[0038] The movable fixing module of the present invention ensures that the base plate can stably and smoothly pass through the bending area of ​​the belt conveyor through the supporting effect of the flexible silicone stick, thereby realizing the continuous clamping and transportation of the preliminary substrate by the adaptive fixing component. When the substrate passes through the vertical support of the flexible silicone stick, it not only avoids the deformation or damage of the base plate caused by bending, but also ensures the stability of the base plate, ensuring that the adaptive fixing component can efficiently and accurately transport the preliminary substrate to the laser module for laser etching of the optical fiber groove in the entire processing flow, thereby improving the overall processing accuracy and efficiency of the system.

[0039] The adapting and 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 arranged to movably pass through the first support rod through a bearing ring, a second rotating shaft arranged to movably pass through the second support rod through a bearing ring, a rotating drive motor fixed to the side rod wall of the first support rod through a corresponding mounting seat and a power output shaft fixedly connected to the first rotating shaft, a rotating plate horizontally arranged between the first support rod and the second support rod, a reinforcement bracket fixed to the rotating plate, and an adsorption bracket fixed to the reinforcement bracket for adsorbing and fixing the bottom surface of the preliminary substrate.

[0040] A first through-hole is provided at the top of the first support rod, and a bearing ring is sleeved on the first through-hole. The first rotating shaft is sleeved on the inner ring of the bearing ring at the first through-hole, so that the first rotating shaft can be rotatably matched with the first through-hole. Similarly, a second through-hole is provided at the top of the second support rod, and a bearing ring is sleeved on the second through-hole. The second rotating shaft is sleeved on the inner ring of the bearing ring at the second through-hole, so that the second rotating shaft can be rotatably matched with the second through-hole, and the first rotating shaft and the second rotating shaft are coaxially arranged.

[0041] The rotary drive motor drives the first rotary shaft to rotate and then synchronously drives the base plate to rotate synchronously. The reinforcement bracket includes two vertical reinforcement rods vertically fixed on the rotary plate and a transverse reinforcement rod connected between the two vertical reinforcement rods.

[0042] The adsorption bracket includes two unit rods connected vertically to each other, adsorption nozzles respectively embedded in the surfaces of the unit rods, a plurality of channel cavities respectively arranged in the unit rods, a plurality of ventilation pipes respectively buried in the channel cavities for connecting the suction holes of the adsorption nozzles in sequence, an air pump for generating negative pressure and installed on the rotating plate at the same time, and a connecting pipe for connecting the adsorption end of the air pump with the ventilation pipe. The negative pressure is generated by driving the air pump so that each adsorption nozzle generates an adsorption force to adsorb and fix the bottom surface of the preliminary substrate. The unit rods are fixed to the reinforcement bracket by bolts. The connecting pipe is selected by technical personnel in this field based on actual needs as a plurality of pipes connecting all ventilation pipes at the same time or a single pipe connecting each ventilation pipe respectively, and is not limited here.

[0043] The preheating module includes a plurality of heating plates evenly laid on the outer rod wall of the unit rod, a temperature sensor for monitoring the temperature change on the surface of the unit rod, and a circuit control board for adjusting the heating power and temperature of the heating plates. Each heating plate is fixed to the outer surface of the unit rod by a high thermal conductivity adhesive layer to form a tightly fitting structure. The heating surface of the heating plate can evenly transfer heat to the unit rod. The heating plate is connected to the control circuit board by a wire. The control circuit board can adjust the heating temperature and heating time of each heating plate according to work needs, thereby realizing precise temperature control of the entire unit rod or a local area. The design of the preheating module evenly conducts heat to the surrounding area of ​​the adsorption nozzle through the unit rod, thereby evenly heating the preliminary substrate, avoiding thermal stress concentration or material damage caused by local overheating or overcooling during laser etching, and improving the etching efficiency of the optical fiber groove of the preliminary substrate.

[0044] The laser module is realized by a laser etcher arranged adjacent to the belt conveyor, and the laser head of the laser etcher is correspondingly located above the belt conveyor. The laser etcher sequentially performs laser etching on the preliminary substrate passing thereunder. The laser etcher is based on the existing high-precision laser processing technology and utilizes the built-in F-Theta focusing lens to precisely focus the high-energy laser beam on the top surface of the preliminary substrate, and performs micron-level precision etching on the optical fiber groove. The laser etcher has the ability to adjust the laser power, pulse frequency and scanning speed in real time to meet the etching depth requirements of different positions of the preliminary substrate, and combines the industrial vision positioning technology to dynamically detect the position and angle of the preliminary substrate, to ensure the precise processing of the laser beam on different areas of the top surface of the preliminary substrate, thereby achieving a high degree of consistency in the size, depth and shape of the optical fiber groove, and ensuring the high precision, high efficiency and stability of the etching operation.

[0045] At the same time, after fixing the preliminary substrate, the adaptive clamping assembly drives the first rotating axis and the second rotating axis to realize precise rotation operation through the rotating drive motor, so that different areas of the top surface of the preliminary substrate can be gradually moved to below the processing area of ​​the laser etcher, thereby realizing continuous etching processing of the entire area of ​​the top surface of the substrate, effectively solving the limitation that the laser etcher can only perform etching operations on the planar area.

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

[0047] The manufacturing system of the present invention adopts modular design and collaborative working mechanism. The preheating module avoids the damage of the preliminary substrate caused by thermal stress through precise temperature management. The movable fixing module ensures the stability of the base plate during transmission through flexible silicone sticks. The adapter fixing component realizes continuous etching of the entire area of ​​the preliminary substrate by rotating the substrate, thereby realizing the efficient production of 90-degree optical fiber array microplates.

[0048] Embodiment 3: Combining with Figure 2 , Attachment Figure 3 and attached Figure 4 In addition to the contents of the above embodiments, the manufacturing system also includes the following specific operation steps:

[0049] S1: Ceramic powder and resin binder are mixed in a preset ratio to form a uniform composite raw material, and the composite raw material is respectively formed into the shape of a preliminary substrate and a cover plate through different molds. Subsequently, the composite raw material with the preliminary substrate and the cover plate is placed in a thermoplastic molding machine for thermoplastic molding to obtain the preliminary substrate and the cover plate;

[0050] S2: At the transport start of the belt conveyor, the preliminary substrate is fixed on the adsorption bracket of the adaptive fixing component in sequence. The adsorption bracket is driven by a negative pressure motor to achieve stable adsorption of the preliminary substrate. The preliminary substrate is sequentially 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 plate is evenly transferred to the preliminary substrate, so that the preliminary substrate reaches a uniform preheating temperature, avoiding the material thermal stress concentration or damage caused by local overcooling or overheating during the laser etching process, thereby improving the stability of laser processing;

[0052] S4: The laser etcher focuses the high-energy laser beam precisely onto the top surface of the preliminary substrate, and the adapter and fixing assembly rotates the drive motor to move different areas of the top surface of the preliminary substrate to the bottom of the laser etcher in sequence, ensuring the consistency of the size, depth and shape of the optical fiber grooves on the top surface of the preliminary substrate;

[0053] S5: After the optical fiber groove etching is completed, the base substrate is transferred to the transmission end of the belt conveyor. The negative pressure motor at the transmission end stops working and releases the processed base substrate. Then, the adsorption bracket returns to the transmission start end through the belt conveyor cycle, and the negative pressure motor restarts to adsorb and fix the new preliminary substrate to enter the next round of processing flow.

[0054] The manufacturing system of the present invention is centered on modular design and fully automated processes, and has the significant advantages of efficient production, high-precision processing, and high-stability operation. It can significantly improve the processing quality and production efficiency of 90-degree optical fiber array microplates, while greatly reducing manual intervention and scrap rates, thus meeting the manufacturing needs of modern optical communication equipment.
