Description

Technical Field

[0001] This invention relates to the field of electronic and optoelectronic fiber drawing technology, and in particular to an electronic and optoelectronic fiber drawing tower. Background Technology

[0002] Electronic and optoelectronic fibers are a new type of fiber fabricated using polymers as a matrix and through the precise integration of various functional materials with different electrical, thermal, optical, acoustic, magnetic, and mechanical properties, including conductors, semiconductors, dielectrics, and insulators. These fibers not only possess the advantages of traditional fibers in terms of flexibility, comfort, and biocompatibility, but also exhibit precise control over multi-scale structures, micro-nano-level feature sizes, and diverse functional integration characteristics. Due to their unique synergistic effect in structure and performance, electronic and optoelectronic fibers show extremely broad application prospects and profound research value in cutting-edge fields such as aerospace, wearable electronics, bioelectronics, and neuroscience.

[0003] The aforementioned characteristics of electronic and optoelectronic fibers dictate that their manufacturing methods must possess highly flexible multi-material design and complex multi-scale structural control features to achieve precise integration of multifunctional materials and low-cost large-scale preparation, thereby meeting the diverse needs of cutting-edge fields such as aerospace, wearable electronics, bioelectronics, and neuroscience. However, at the same time, the interfacial properties between multi-component materials, the strict control of process parameters, and the issues of structural stability and repeatability also pose certain challenges to their high-end applications and industrialization.

[0004] Traditional fiber manufacturing methods, such as melt spinning, solution spinning, and electrospinning, are insufficient to meet the requirements of flexible multi-material design and precise control of complex structures in electronic and optoelectronic fibers. Furthermore, they still have shortcomings in terms of fiber consistency, multi-functional integration, production efficiency, and controllability, which limit their application in the large-scale production of electronic and optoelectronic fibers.

[0005] The thermal drawing technology, capable of producing multi-material fibers, has opened up a promising research path for the innovative manufacturing and rapid development of electronic and optoelectronic fibers. Originally invented for the mass production of silica optical fibers for communication, thermal drawing involves a core-cladding structure from a silica preform to optical fibers with micron-scale diameters. The drawing tower, as the core device in thermal drawing, plays a decisive role in the quality of the drawn fibers. Currently, the drawing process and production standards for silica optical fibers are relatively mature, and conventional drawing towers can meet the drawing requirements. However, for electronic and optoelectronic fibers, due to their low melting point and complex structure, the high drawing temperature and high drawing speed of conventional drawing towers are no longer suitable. This makes it difficult to achieve high-precision drawing of electronic and optoelectronic fibers, and conventional drawing towers cannot meet the drawing requirements of electronic and optoelectronic fibers, which need to precisely integrate various functional materials with different electrical, thermal, optical, acoustic, magnetic, and mechanical properties, such as conductors, semiconductors, dielectrics, and insulators. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned technical problems and provide a fiber drawing tower for electronic and optoelectronic fibers. The drawing speed of the drawing system can be adjusted according to the initial fiber diameter monitored by the diameter measuring system. In conjunction with the suspension system, it can meet the high-precision drawing of electronic and optoelectronic fibers, effectively solving the current problem that it is difficult to achieve efficient and high-quality drawing of electronic and optoelectronic fibers. At the same time, by utilizing the property imparting system, it can impart magnetic, piezoelectric or ferroelectric properties to the core wire, meeting the drawing requirements of electronic and optoelectronic fibers that need to integrate various functional materials with different electrical, thermal, optical, acoustic, magnetic and mechanical properties, such as conductors, semiconductors, dielectrics and insulators.

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments analyzed and obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] The purpose of this invention is to provide a drawing tower for electronic and optoelectronic fibers to solve the problems existing in the prior art. Under the action of the suspension system, the feeding system, the diameter measuring system and the drawing system, it can realize the long-distance and efficient drawing of multifunctional, multi-material or complex structure electronic and optoelectronic fibers. It effectively solves the problem that it is difficult to achieve efficient and high-quality drawing of electronic and optoelectronic fibers. At the same time, by utilizing the property imparting system, it can impart magnetic, piezoelectric or ferroelectric properties to the core wire, which meets the drawing requirements of electronic and optoelectronic fibers that need to integrate a variety of functional materials with different electrical, thermal, optical, acoustic, magnetic and mechanical properties, such as conductors, semiconductors, dielectrics and insulators.

[0064] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] like Figures 1 to 25 As shown, this embodiment provides an electronic and optoelectronic fiber drawing tower, including a tower body, a suspension system 1, a fiber feeding system 2, a heating system 3, a diameter measuring system 5, a drawing system 6, a fiber take-up system 7, and a property assignment system.

[0066] The suspension system 1 is used to place and drive the preform 204 (usually a polymer) to move horizontally and vertically within the tower body and to rotate around its own axis (the preform 204 itself). The suspended end of the preform 204 is suspended by a weight.

[0067] The feeding system 2 is used to feed the inner core filament (e.g., guide wire or fiber) into the reserved channel of the preform 204.

[0068] The heating system 3 is used to soften the preform 204 to achieve a drawing state (at which point the temperature of the preform 204 is between its glass transition temperature and viscous flow temperature), so that the preform 204 will naturally droop under the pull of a heavy object to form initial fibers.

[0069] The diameter measurement system 5 is used to monitor the diameter of the initial fiber in real time.

[0070] The drawing system 6 is used to receive and draw the initial fibers to form finished fibers, and adjusts the drawing speed according to the monitoring data of the diameter measuring system 5 to control the fiber diameter and obtain finished fibers of the required specifications that are consistent with the preform 204 in terms of material properties and geometry.

[0071] The fiber winding system 7 is used to wind the finished fibers inside the tower to the outside of the tower for storage.

[0072] And a property assignment system, which is used to assign magnetic, piezoelectric or ferroelectric properties to the inner core wire.

[0073] In this electronic and optoelectronic fiber drawing tower, the drawing speed of the drawing system 6 can be adjusted according to the initial fiber diameter monitored by the diameter measuring system 5, so as to achieve high-precision drawing of electronic and optoelectronic fibers. At the same time, the property imparting system can impart magnetic, piezoelectric or ferroelectric properties to the inner core wire, which meets the drawing requirements of electronic and optoelectronic fibers that need to integrate various functional materials with different electrical, thermal, optical, acoustic, magnetic and mechanical properties, such as conductors, semiconductors, dielectrics and insulators.

[0074] In one embodiment, the suspension system 1 includes a Z-axis moving mechanism, an X-axis moving mechanism, a Y-axis moving mechanism, and a rotation mechanism. The Z-axis moving mechanism includes a control motor 101, a drive screw 102, a moving bracket, and vertical guide rods. The control motor 101 is installed inside the tower body, with its motor shaft facing downwards. The drive screw 102 is coaxially fixedly connected to the motor shaft of the control motor 101 and can be connected via a coupling. The vertical guide rod is vertically positioned beside the drive screw 102 and is installed inside the tower body. The moving bracket is threadedly connected to the drive screw 102 with a nut and is slidably connected to the vertical guide rods. Preferably, the moving bracket is a triangular bracket, and there are three vertical guide rods, with the three corners of the triangular bracket slidably connected to the three vertical guide rods respectively. The X-axis moving mechanism includes a horizontally arranged X-axis linear guide rail 103, which is installed on the moving bracket. The Y-direction moving mechanism includes a horizontally arranged Y-direction linear guide 104, which is mounted on a movable slider of the X-direction linear guide 103 and is perpendicular to the X-direction linear guide 103. The rotation mechanism includes a rotatable multi-jaw chuck 105, which is rotatably connected to the movable slider of the Y-direction linear guide 104 for gripping the preform 204. Preferably, the multi-jaw chuck 105 is a three-jaw chuck.

[0075] The motor shaft of the control motor 101 rotates, causing the drive screw 102 to rotate forward or backward. Under the action of the vertical guide rod and nut, the moving bracket moves up or down, which in turn drives the X-axis linear guide 103, the Y-axis linear guide 104, and the multi-jaw chuck 105 to move up and down, thereby realizing the vertical movement of the preform 204, i.e., Z-axis movement. The sliding block of the X-axis linear guide 103 moves along the X-axis linear guide 103, which can drive the Y-axis linear guide 104 and the multi-jaw chuck 105 to move horizontally in the X direction. The sliding block of the Y-axis linear guide 104 moves along the Y-axis linear guide 104, which can drive the multi-jaw chuck 105 to move horizontally in the Y direction, thereby realizing the horizontal movement of the preform 204. The rotation of the multi-jaw chuck 105 can realize the rotation of the preform 204.

[0076] In one embodiment, the weight can be a weight of different weights, which is suspended at the bottom of the preform 204. As it is heated and softened, the heated core of the preform 204 naturally droops and thins to form the initial fibers.

[0077] In one embodiment, the wire feeding system 2 includes a fixed rod 201, a wire feeding reel 202, and a hollow rod 203. The top of the fixed rod 201 is clamped by a multi-jaw chuck 105, and the wire feeding reel 202 is fixedly installed in the middle of the fixed rod 201. The top of the hollow rod 203 is inserted into the bottom of the fixed rod 201, and the bottom of the hollow rod 203 is for the insertion of a preformed rod 204. The sidewall of the hollow rod 203 is provided with guide tubes. The number of guide tubes can be the same as or greater than the number of reserved channels in the preformed rod 204, and the number of reserved channels is the same as the number of inner core wires. The inner core wires are led out from the wire feeding reel 202, enter the hollow rod 203 through the guide tubes, and are then fed into the reserved channels of the preformed rod 204. The wire feeding reel 202 can feed any number and any type of inner core wire (wire or fiber). The hollow rod 203 can be equipped with a corresponding number of guide tubes depending on the number of wires fed.

[0078] In one embodiment, the feed spool 202 is provided with feed rollers for conveying inner core wires. The number of feed rollers can match the number of inner core wires. For example, one feed roller is used to convey one set of inner core wires, and multiple feed rollers are provided to convey the same number of sets of inner core wires as the number of feed rollers. Alternatively, the number of feed rollers can be greater than the number of inner core wires, such as three feed rollers, one of which conveys one set of inner core wires.

[0079] In one embodiment, the heating system 3 includes a heating furnace 301 and a heating controller 302, with the heating furnace 301 located inside the tower. The heating furnace 301 includes an upper heating zone, a middle heating zone, and a lower heating zone arranged sequentially from top to bottom. The top of the heating furnace 301 has a rod inlet communicating with the upper heating zone, and the bottom of the heating furnace 301 has a fiber outlet communicating with the lower heating zone. The rod inlet allows the preformed rods 204 to enter, and the fiber outlet allows the initial fibers to extend. The heating controller 302 is located outside the tower and can independently regulate the temperatures of the upper heating zone, the middle heating zone, and the lower heating zone. Driven by the suspension system 1, the preform 204 extends into the heating furnace 301. The temperature of each area in the upper, middle, and lower heating zones is controlled by the heating controller 302. Generally, the temperature of the middle heating zone is higher than that of the upper and lower heating zones, and the temperature of the upper heating zone is usually higher than that of the lower heating zone. The upper heating zone is used to preheat the preform 204, the middle heating zone is used to heat and soften the preform 204, and the lower heating zone is used to keep the fibers warm to prevent breakage due to sudden temperature drops. For example, the heating temperatures of the upper, middle, and lower heating zones can be set to 90℃, 245℃, and 85℃ respectively. Of course, these parameters are just examples and can be adjusted according to actual needs and circumstances. The typical operating temperature of the heating furnace 301 is 250℃~350℃, and can reach up to 500℃ in air; the temperature controllable range of the lower heating zone is from room temperature to 300℃. The vertical position of the preform 204 needs to be adjusted according to the fiber drawing process.

[0080] In one embodiment, the heating furnace 301 includes a stainless steel furnace shell 30103, with a rod inlet and a wire outlet at the top and bottom, respectively. An upper furnace opening fixing ring 30102 is provided on the rod inlet, and a magnetically attached heat-insulating ring 30101 is magnetically attached to the upper furnace opening fixing ring 30102. A lower furnace opening fixing ring 30109 is provided on the wire outlet, and an openable lower furnace opening cover 30110 is provided on the lower furnace opening fixing ring 30109. Both the upper furnace opening fixing ring 30102 and the lower furnace opening fixing ring 30109 are provided with a first slot, a second slot, and a third slot. The upper heating zone, the middle heating zone, and the lower heating zone are located between the upper furnace opening fixing ring 30102 and the lower furnace opening fixing ring 30109. The interior of the stainless steel furnace shell 30103 is provided with a protective cover 30104, a heat-insulating layer 30105, and a quartz tube 30108 arranged sequentially from the inside out. The top and bottom of the quartz tube 30108 are respectively secured in the first slots of the upper furnace opening fixing ring 30102 and the lower furnace opening fixing ring 30109, with the quartz tube 30108 vertically penetrating the center of the furnace. The top and bottom of the insulation layer 30105 are respectively secured in the second slots of the upper furnace opening fixing ring 30102 and the lower furnace opening fixing ring 30109. The top and bottom of the protective cover 30104 are respectively secured in the third slots of the upper furnace opening fixing ring 30102 and the lower furnace opening fixing ring 30109. A nickel-plated copper tubular insert 30107 is fitted over the quartz tube 30108, which improves the temperature uniformity of each heating zone. Nickel-chromium windings 30106 are installed in the upper, middle, and lower heating zones, and are wound around the outer ring surface of nickel-plated copper tubular inserts 30107. The outer ring surface of the nickel-chromium windings 30106 is in contact with the inner ring surface of the insulation layer 30105. The inner ring surface of the protective cover 30104 is in contact with the outer ring surface of the insulation layer 30105. The outer ring surface of the protective cover 30104 is in contact with the inner wall of the stainless steel furnace shell 30103. The protective cover 30104, the insulation layer 30105, and the quartz tube 30108 are coaxial. Three sets of thermocouples 30111 are installed on the stainless steel furnace shell 30103, corresponding to the upper, middle, and lower heating zones respectively. Thermocouples 30111 and nickel-chromium windings 30106 are electrically connected to the heating controller 302. The heating controller 302 sets the temperature of each heating zone in the upper, middle, and lower heating zones. The nickel-chromium windings 30106 in the three heating zones are energized and heated accordingly. At the same time, the heating controller 302 can receive and display the monitored temperatures of the three thermocouples 30111 in real time to know the temperature in each heating zone. Then, by controlling the nickel-chromium windings 30106 in each heating zone, the temperature of the three heating zones can be precisely controlled.

[0081] In one embodiment, the insulation layer 30105 is composed of simplified ceramic fibers, which can both insulate and achieve rapid cooling, thereby enabling precise and efficient temperature control.

[0082] In one embodiment, the outer diameter of the quartz tube 30108 is 50 mm, and the inner diameter can be set as needed. The quartz tube 30108 can be replaced at any time.

[0083] In one embodiment, each of the three sets of thermocouples 30111 includes multiple thermocouples 30111. The thermocouples 30111 corresponding to the three heating zones are inserted at 90° intervals with the center of each heating zone as the center, enabling multi-directional monitoring of the temperature of the corresponding heating zone. Preferably, the thermocouples 30111 can be replaced on-site, with a total of 12 thermocouples 30111, all of which are K-type thermocouples with a diameter of 0.8 mm. Four thermocouples are inserted at 90° intervals in each of the upper, middle, and lower heating zones.

[0084] In one embodiment, the diameter measurement system 5 includes a laser diameter gauge located below the heating furnace 301. The laser diameter gauge includes a transmitter and a receiver, with a measurement area between the transmitter and receiver for the initial fiber to pass through. The laser diameter gauge uses a laser diode as the light source (transmitter) and is combined with an adaptive signal processing measurement head (receiver), possessing high data packet characteristics such as single-scan calibration, monitoring, and high data rate output. Vibration during the drawing process has no significant impact on the measurement results, and the minimum measurable diameter is 15 micrometers. Preferably, the laser diameter gauge is located 0.5 m below the heating furnace 301, but this position can be adjusted according to actual conditions.

[0085] In one embodiment, the drafting system 6 includes positioning wheels 601 and traction wheels 602. Positioning wheels 601 guide the initial fibers vertically downwards. The number of positioning wheels 601 is set as needed; specifically, the positioning wheels 601 are arranged in two rows, staggered, meaning that one row of positioning wheels 601 corresponds exactly to the distance between two adjacent positioning wheels 601 in the other row. Preferably, three positioning wheels 601 can be used, with one row having two positioning wheels 601 and the other row having one positioning wheel 601. Traction wheels 602 are used to pull the initial fibers guided by the positioning wheels 601 to form a stable drawn state. Typically, there are two traction wheels 602, which are tracked traction wheels. The drafting system 6 is located below the diameter measuring system 5 (laser diameter gauge). After the preform 204 is heated and softened in the heating furnace 301, it becomes fibrous (initial limit). Under the action of a weight, the fibers hang naturally, passing through multiple positioning wheels 601, and then fall between two traction wheels 602. They are pulled by the tracks of the traction wheels 602 to form a stable filament state. By adjusting the feed speed of the suspension system 1 and the filament drawing speed of the traction wheels 602, and simultaneously monitoring the fiber diameter in real time through the diameter measuring system 5, the fiber diameter is kept within a set range.

[0086] In one embodiment, the take-up system 7 includes a guide wheel 701, a tension detection wheel 702, a take-up roller 703, and a take-up controller 704. The finished fiber is sequentially conveyed through the guide wheel 701 and the tension detection wheel 702 to the take-up roller 703, which connects to the finished fiber to achieve winding. The take-up controller 704 collects the tension of the finished fiber detected by the tension detection wheel 702 to regulate the take-up speed of the take-up roller 703, matching the drawing speed of the drafting system 6 (such as the traction wheel 602). Specifically, after the preform 204 becomes finished fiber and passes through the traction wheel 602, the larger end (including the weight) of the finished fiber is cut off, leaving the thinner fiber. Then, the fiber is manually drafted, sequentially passing through the guide wheel 701 and the tension detection wheel 702, and then adhered to the take-up roller 703 to achieve winding.

[0087] In one embodiment, the property imparting system includes a magnetization module 8 and a high-voltage in-situ polarization module 9. The magnetization module 8 includes a pulse magnetizer located between the heating furnace 301 and the laser diameter measuring device (diameter measuring system 5). The magnetization coil of the pulse magnetizer is used to allow the initial fiber to pass through. The pulse magnetizer releases a large current into the magnetization coil through a capacitor discharge pulse, generating an extremely strong pulsed magnetic field (typically 1 T to 6 T), causing the magnetic core wire to reach a saturated magnetization state, and the internal magnetic domains to tend to be uniformly arranged, thus obtaining macroscopic magnetic properties. Preferably, the pulse magnetizer can be a digital pulse magnetizer, which has the characteristics of precision, controllability, safety, and intelligence. The magnetization coil is located 0.2 m below the heating furnace 301, and can be adjusted according to the actual situation.

[0088] The high-voltage in-situ polarization module 9 is located outside the tower body. The positive terminal of the high-voltage in-situ polarization module 9 is connected to the inner core wire (a portion of the inner core wire on the feed disc 202) fed by the feed system 2, and the negative terminal of the high-voltage in-situ polarization module 9 is connected to the inner core wire at the end of the finished fiber in the take-up system 7. A DC high-voltage power supply is used to provide high voltage (usually 100V~3000V) to apply an electric field to the piezoelectric or ferroelectric inner core wire, causing its internal dipoles to align along the direction of the electric field, thereby obtaining stable piezoelectric or ferroelectric properties.

[0089] In one embodiment, an integrated control system 4 is also included. The integrated control system 4 controls the suspension system 1, the feed system 2, the heating system 3, the diameter measuring system 5, the drawing system 6, the take-up system 7, and the property assignment system. The suspension system 1, feed system 2, heating system 3, diameter measuring system 5, drawing system 6, take-up system 7, and property assignment system are multiple subsystems at the same level. The integrated control system 4 is a higher-level system, monitoring the working status and operating parameters of each subsystem in real time and correcting the working status of each subsystem by adjusting the operating parameters. The heating system 3, take-up system 7, and property assignment system can be individually controlled by their respective system controllers. Through the synergistic effect of all systems, the operation of a multi-physics (thermal, mechanical, magnetic, and electrical) coupled electronic and optoelectronic fiber drawing tower is ultimately achieved. This forms a novel drawing tower that can precisely integrate multifunctional materials, accurately and rapidly control the temperature field distribution, and adjust the preform movement state from multiple directions. It is highly efficient, controllable, scalable, and specifically designed for the production of high-quality electronic and optoelectronic fibers through thermal, mechanical, magnetic, and electrical multi-physics coupling, enabling industrial production and cutting-edge applications.

[0090] In one embodiment, the workflow of the electronic and optoelectronic fiber drawing tower is as follows:

[0091] First, the multi-jaw chuck 105 clamps, positions, and rotates the fixed rod 201 in the wire feeding system 2. Through the cooperation of the control motor 101, drive screw 102, nut, and vertical guide rod, the wire feeding system 2 is controlled to move up and down. The X-axis linear guide rail 103 controls the wire feeding system 2 to move left and right. The Y-axis linear guide rail 104 controls the wire feeding system 2 to move forward and backward. Through the coordinated operation of the various parts of the suspension system 1, the wire feeding system 2 is controlled to translate and rotate in six directions (up, down, left, right, forward, and backward) to adjust the spatial position of the preform rod 204.

[0092] Then, the inner core wire is led out from the feed spool 202, enters the hollow rod 203 through the guide tube, and is then fed into the corresponding channel of the preform 204. Under the temperature field of the heating furnace 301 and the tensile stress of the traction wheel 602, the preform 204 undergoes axial dynamic extension and radial dynamic contraction, and is drawn into fibers. The feed spool 202 automatically feeds the inner core wire downwards with this change, realizing the high-precision self-assembly of the embedded circuit structure in the fiber. At the same time, the fiber drawn after being heated and softened by the heating furnace 301 first passes through the magnetization module 8 and then through the diameter measuring system 5. If magnetic properties are required at this time, the magnetization module 8 is turned on. The magnetic material in the fiber is subjected to an extremely strong pulsed magnetic field, and the internal magnetic domains tend to be aligned uniformly, thereby obtaining macroscopic magnetic properties. Then, when the fiber passes through the laser diameter measuring device of the diameter measuring system 5, the light source (emitting end) of the laser diode irradiates the fiber surface. The measuring head (receiving end) monitors and performs adaptive signal processing on the collected data, and finally displays the diameter of the fiber in real time on the screen of the integrated control system 4. After passing through the diameter measuring system 5, the fiber passes through three positioning wheels 601; then it is pulled by the track on the traction wheel 602 to form a stable drawing state; the feeding speed of the suspension system 1 and the drawing speed of the traction wheel 602 are adjusted by the integrated control system 4, and the fiber diameter is monitored in real time by the diameter measuring system 5 to keep the fiber diameter within the set range.

[0093] Then, the fiber pulled from the traction wheel 602 changes direction through the guide wheel 701, and after passing through the tension detection wheel 702, it is connected to the take-up roller 703. The take-up controller 704 monitors the tension of the fiber when it passes through the tension detection wheel 702 in real time and adjusts the take-up speed of the take-up roller 703 to match the pulling speed of the traction wheel 602.

[0094] Finally, the take-up roller 703 stores the finished fiber. If it is necessary to impart piezoelectric or ferroelectric properties to the finished fiber, a high voltage (100V~3000V) is provided by a DC high voltage power supply to apply an electric field to the piezoelectric or ferroelectric core wire, so that the internal dipoles are aligned along the direction of the electric field to obtain stable piezoelectric or ferroelectric properties.

[0095] Compared with existing technologies, this electronic and optoelectronic fiber drawing tower has the following advantages:

[0096] ① The fiber feeding system 2 can feed any number of functional materials with different electrical, thermal, optical, acoustic, magnetic and mechanical properties, such as conductors, semiconductors, dielectrics and insulators, into the fiber and achieve precise integration.

[0097] ② The heating furnace 301 adopts a zoned design, which can set the heating temperature of three heating zones according to the characteristics of different electronic and optoelectronic preforms 204, so as to achieve precise control of the drawing temperature and temperature field distribution, thereby drawing electronic and optoelectronic fibers in a uniform, continuous, efficient and high-quality manner.

[0098] ③ The suspension system 1 can achieve precise control of the preform 204 in six degrees of freedom, including coordinated control of three-dimensional linear displacement and three-axis rotation in the up / down / left / right / front and back directions. Unlike existing wire drawing equipment that can only adjust a single direction or requires manual intervention, this system enables long-distance and efficient drawing of multi-material or complex structure electronic and optoelectronic fibers.

[0099] ④ The magnetization module 8 and the high-voltage in-situ polarization module 9 are integrated into the drawing tower for the first time. They can apply magnetic and electric fields in real time during the drawing process to achieve synchronous control of the magnetic or polar structure inside the fiber, giving it magnetic, piezoelectric or ferroelectric properties.

[0100] ⑤ This electronic and optoelectronic fiber drawing tower features multi-physics field (thermal, magnetic, and electrical) coupling capabilities, offering a wide range of applications. It overcomes the technical bottlenecks of traditional drawing towers, such as limited functionality, rigid structure, and inability to adapt to the in-situ control requirements of functional fibers. It boasts significant advantages including high system integration, high degree of control freedom, and programmable functional fields. It can feed any number of various functional materials, is compatible with electronic and optoelectronic preforms of any material, operates at temperatures up to 500℃, and can draw electronic and optoelectronic fibers with diameters exceeding 15 micrometers.

[0101] In one embodiment, seven experimental examples of electron and optoelectronic fiber drawing towers are provided for illustration:

It is a cuboid with a length of 160 mm, a width of 24.5 mm, and a height of 11.5 mm. It contains two layers of carbon-doped polyethylene (CPE) and one layer of organic-inorganic hybrid piezoelectric material in the middle.
