Technical Field
[0001] The present application relates to the field of textiles, and in particular, to a functional yarn and a preparation method and system thereof. Background Art
[0002] As the Internet of Things (IoT) and smart textiles are increasingly integrated, RFID (Radio Frequency Identification) tags, as a key technology for tracking, managing and exchanging information about textiles, have become the focus of industry attention in terms of their integration and durability. However, current RFID tags have the problem of poor signal stability, which affects the ability of RFID tags to achieve their corresponding functions. Summary of the invention
[0003] In view of this, the purpose of the embodiments of the present application is to provide a functional yarn and a preparation method and system thereof, which can improve data transmission efficiency, enhance communication flexibility, and improve communication quality.
[0004] In the first aspect, an embodiment of the present application provides a functional yarn, comprising: a target processor, a first antenna, a second antenna, and a coated yarn; one end of the first antenna is connected to a first target pin of the target processor; one end of the second antenna is connected to the first antenna, and the other end of the second antenna is connected to the first antenna or the second target pin of the target processor; wherein the second antenna and the first antenna are configured to form a loop to provide an antenna with a wide bandwidth; the coated yarn is coated on the surface of the first antenna, the second antenna, and the target processor.
[0005] In the above implementation process, by directly integrating the target processor into the coated yarn, the functional yarn manufacturing process is simplified and the integration efficiency is improved. Moreover, this direct integration method can directly combine the functional yarn with the existing weaving and embroidery process, and weave the functional yarn into the fabric, thereby reducing production costs and improving production efficiency. In addition, by setting a second antenna, and the second antenna is connected to two first antennas, or the second antenna is connected to the first antenna and the second target pin of the target processor, the first antenna and the second antenna can form a ring structure, thereby increasing the bandwidth of the first antenna, forming a wide-bandwidth antenna, thereby improving data transmission efficiency, enhancing communication flexibility, and improving communication quality.
[0006] In one embodiment, there are multiple first antennas; the multiple first antennas form at least one dipole antenna; one end of each second antenna is connected to one of the first antennas in the dipole antennas, and the other end of the second antenna is connected to another of the first antennas in the dipole antennas.
[0007] In the above implementation process, since the dipole wire has omnidirectional radiation characteristics and is easy to match and integrate, when there are multiple first antennas, setting the first antenna as a dipole antenna can increase the radiation performance of the first antenna, while reducing the structure of the first antenna, thereby reducing the difficulty of matching and integration of the first antenna. In addition, the two ends of the second antenna are respectively connected to the two first antennas in the dipole antenna to form a ring, thereby providing a wide-bandwidth antenna, improving data transmission efficiency, enhancing communication flexibility, and improving communication quality.
[0008] In one embodiment, the dipole antenna is a curved dipole antenna; wherein the curved dipole antenna is configured such that the first antenna is arranged in a curved shape on the target processor; and / or the dipole antenna is a linear dipole antenna; wherein the linear dipole antenna is configured such that the first antenna is arranged in a linear shape on the target processor.
[0009] In the above implementation process, by shaping the first antenna in the functional yarn into different geometric shapes, a variety of dipole antennas (such as curved dipole antennas and / or straight dipole antennas) can be formed, which can improve the performance and effect of the first antenna, optimize the signal reception and transmission efficiency of the first antenna, improve the accuracy and stability of the target controller, optimize the signal reception and transmission efficiency, and improve the recognition accuracy and stability of the functional yarn. In addition, different types of functional yarns can be set according to different application requirements to increase the flexibility of the functional yarn, which can be applied to a variety of different textile materials and application scenarios, and increase the application range and applicability of the functional yarn.
[0010] In one embodiment, the first antenna is connected to the first target pin by welding; and / or the second antenna is connected to the first antenna or the second target pin by welding.
[0011] In the above implementation process, welding can form a larger contact area on the connection surface compared to other connection methods, and has better firmness and shock resistance. By welding the first antenna to the first target pin, and / or welding the second antenna to the first antenna or the second target pin, the connection strength between the first antenna and the target processor and / or the connection strength between the second antenna and the first antenna and the target processor is increased. In addition, by welding the antennas, the use of glue and colloid adhesives in the functional yarn can be reduced, and the discomfort caused by the contact between the colloid material and the skin when the functional yarn is used on fabric can be reduced, thereby enhancing the user experience.
[0012] In one embodiment, an adhesive is coated on a surface of the target processor; wherein the adhesive is configured to wrap connection points between the first antenna, the second antenna, and the target processor.
[0013] In the above implementation process, by setting an adhesive, the adhesive can wrap the target processor and the connection points between the first antenna, the second antenna and the target processor inside it, thereby reinforcing the connection points between the first antenna, the second antenna and the target processor and improving the connection stability between the first antenna, the second antenna and the target processor.
[0014] In one embodiment, the target processor is surrounded and filled with a thermosetting polymer material to achieve a yarn hammer-shaped packaging for the target processor.
[0015] In the above implementation process, by packaging the target processor in a yarn hammer shape, the influence of shear force on the target controller, the first antenna and the second antenna can be reduced, thereby improving the stability and safety of the first antenna and the second antenna.
[0016] In a second aspect, an embodiment of the present application also provides a method for preparing a functional yarn, which is used to prepare the functional yarn described in the first aspect or any one of the first aspect, and the method comprises: connecting a first target pin of a target processor to one end of a first antenna; and connecting a second antenna to a second target pin of the first antenna and / or the target processor; wrapping a coated yarn on the surface of the first antenna, the second antenna and the target processor to obtain the functional yarn.
[0017] In the above implementation process, a functional yarn including a target processor can be made by connecting the target processor, the first antenna, and the second wire and wrapping them in a coated yarn. Since the target processor and the first antenna are provided in the functional yarn, the corresponding function of the target processor can be executed. In addition, by wrapping the coated yarn on the surface of the first antenna, the second antenna and the target processor, the functional yarn can be made into the appearance of ordinary yarn, and then can be woven on the fabric. On the one hand, the production cost of the functional yarn can be reduced. On the other hand, directly integrating the target processor into the coated yarn can make the target processor have better durability, reduce the risk of the target processor falling off, increase the application scenarios of the functional yarn, and improve the durability and flexibility of the functional yarn.
[0018] In one embodiment, wherein, the first antenna includes multiple antenna shapes; the antenna shape is configured as the shape presented by the first antenna on the target processor; before connecting the first target pin of the target processor with one end of the first antenna, the method further includes: determining the bandwidth corresponding to the first antenna of each antenna shape; determining that among one or more antenna shapes that meet the bandwidth condition, the antenna structure with the largest contact area between the first antenna and the target processor is the target antenna shape; connecting the first target pin of the target processor with one end of the first antenna includes: connecting the first antenna to the first target pin according to the target antenna shape.
[0019] In the above implementation process, by determining the shape of the target antenna according to the bandwidth of the first antenna and the contact area between the first antenna and the target processor, the signal transmission capability of the first antenna can be improved. On the other hand, the connection strength between the first antenna and the target processor can be improved, and the wear resistance of the functional yarn can be improved.
[0020] In one embodiment, before wrapping the coated yarn on the surfaces of the first antenna, the second antenna and the target processor to obtain the functional yarn, the method further includes: applying an adhesive on the surface of the target processor; placing the target processor in a shuttle-shaped mold when the adhesive is dry; filling the shuttle-shaped mold with a liquid thermosetting polymer material; and removing the target processor from the shuttle-shaped mold after the thermosetting polymer material is cured.
[0021] In the above implementation process, by setting an adhesive, the adhesive can wrap the target processor and the connection points between the first antenna, the second antenna and the target processor, thereby reinforcing the connection points between the first antenna, the second antenna and the target processor, and improving the connection stability between the first antenna, the second antenna and the target processor. In addition, by encapsulating the target processor in a yarn hammer shape, the influence of shear force on the target controller, the first antenna and the second antenna can be reduced, and the stability and safety of the first antenna and the second antenna can be improved.
[0022] In the second aspect, an embodiment of the present application also provides a functional yarn preparation system, which executes the second aspect, or the method in any one of the embodiments of the second aspect, and the system includes: a wrapping device, a clamping device and a connecting device; the clamping device is used to clamp the first antenna and place one end of the first antenna at the first target pin; the connecting device is used to connect the first target pin with one end of the first antenna; the clamping device is also used to clamp the second antenna and place the second antenna on the first antenna and / or the second target pin of the target processor; the connecting device is also used to connect the second antenna with the first antenna and / or the second target pin of the target processor; the wrapping device is used to wrap the coated yarn on the surface of the first antenna, the second antenna and the target processor to obtain the functional yarn.
[0023] In the above implementation process, the wrapping device, the clamping device and the connecting device are provided to realize the automatic production of the functional yarn, thereby reducing the number of staff required for the production of the functional yarn and reducing the labor cost.

[0039] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application.
[0040] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0041] Currently, there are some problems with the integration of traditional functional tags on textiles, which requires the target controller to be fixed on a rigid base and then fixed to the fabric. This method has some challenges when used on textiles because commonly used controller fixing techniques, such as welding and bonding, are not suitable for textile materials and may cause the controller to be damaged during movement, stretching or washing, thus affecting the durability of textile-based functional tags.
[0042] In addition, the inventors of the present application have discovered through long-term research that, limited by the structure of the functional yarn, the bandwidth of the antenna in the current functional yarn is relatively small, which greatly affects the data transmission efficiency, communication flexibility and communication quality of the functional yarn.
[0043] In view of this, the present application proposes a smart yarn that integrates a target controller into a functional yarn. A single conductive fiber can be used as a radiating element of an antenna, and the target controller can be directly welded to the terminal of the conductive fiber. The conductive fiber together with the embedded target controller is wrapped in a layer of non-conductive fiber to form a functional yarn. The functional yarn can be used seamlessly like ordinary yarn and woven or knitted into fabrics through traditional manufacturing processes.
[0044] In addition, by setting up a second antenna, and the second antenna is connected to two first antennas, or the second antenna is connected to the first antenna and the second target pin of the target processor, the first antenna and the second antenna can form a ring structure, thereby increasing the bandwidth of the first antenna to form a wide-bandwidth antenna, thereby improving data transmission efficiency, enhancing communication flexibility, and improving communication quality.
[0045] To facilitate understanding of this embodiment, a functional yarn disclosed in the embodiment of this application is first introduced in detail.
[0046] like Figure 1 , Figure 2 As shown, Figure 1 , Figure 2 The functional yarn in the embodiment of the present application is shown, including: a target processor 110, a first antenna 120, a second antenna 130 and a coated yarn.
[0047] One end of the first antenna 120 is connected to the first target pin of the target processor 110; one end of the second antenna 130 is connected to the first antenna 120, and the other end of the second antenna 130 is connected to the first antenna 120 ( Figure 1 ) or a second target pin ( Figure 2 The coated yarn is coated on the surface of the first antenna 120, the second antenna 130 and the target processor 110.
[0048] Optionally, the first antenna 120 may be made of one or more materials such as conductive fiber, conductive polymer, carbon fiber, metal coated fiber, conductive coated yarn, radiating element, etc.
[0049] The second antenna 130 may also be made of one or more materials such as conductive fiber, conductive polymer, carbon fiber, metal coated fiber, conductive coated yarn, etc.
[0050] The first antenna 120 and the second antenna 130 may be the same or different, and the first antenna 120 and the second antenna 130 may be configured according to actual needs.
[0051] The first antenna 120 here may include one or more antennas, and the first antenna 120 may be used to form a monopole antenna ( Figure 1 ), dipole antenna ( Figure 2 , Figure 3 ), directional antennas, and one or more types of antenna structures.
[0052] The number and location of the second antenna 130 may be determined according to the antenna structure formed by the first antenna 120 .
[0053] Exemplarily, if the functional yarn includes a first antenna 120 that forms a monopole antenna, a second antenna 130 is correspondingly provided, one end of the second antenna 130 is connected to the first antenna 120 , and the other end of the second antenna 130 is connected to a second target pin of the target processor 110 .
[0054] If the functional yarn includes two first antennas 120, and the two first antennas 120 form a dipole antenna, a second antenna 130 is correspondingly provided, one end of the second antenna 130 is connected to one of the first antennas 120 in the dipole antenna, and the other end of the second antenna 130 is connected to another first antenna 120 in the dipole antenna.
[0055] If the functional yarn includes three first antennas 120, and the three first antennas 120 form a monopole antenna and a dipole antenna, two second antennas 130 may be provided accordingly. One end of one second antenna 130 is connected to the first antenna 120, and the other end is connected to the second target pin of the target processor 110. One end of another second antenna 130 is connected to one first antenna 120 of the dipole antenna, and the other end is connected to another first antenna 120 of the dipole antenna.
[0056] The above-mentioned configuration of the first antenna 120 and the second antenna 130 is only exemplary, and the configuration and quantity of the first antenna 120 and the second antenna 130 can be adjusted according to actual conditions.
[0057] Optionally, the first antenna 120 and the target processor 110 may be connected by laser welding, conductive adhesive bonding, ultrasonic welding, etc. The connection method of the first antenna 120 and the target processor 110 may be selected according to actual conditions.
[0058] The connection method between the second antenna 130 and the first antenna 120, and the connection method between the second antenna 130 and the target processor 110 may also be laser welding, conductive adhesive bonding, ultrasonic welding, etc. The connection method between the second antenna 130 and the first antenna 120, and the connection method between the second antenna 130 and the target processor 110 may be selected according to actual conditions.
[0059] The target processor 110 here refers to a device that can perform corresponding functions, such as an RFID (Radio Frequency Identification) chip, a sensor, a microchip, a microprocessor, etc. The target processor 110 can be selected according to actual conditions.
[0060] The above-mentioned covered yarn refers to common yarn used for textile weaving, for example, cotton yarn, wool yarn, linen yarn, silk yarn, blended yarn, etc. The covered yarn can be selected according to actual conditions.
[0061] After the coated yarn is coated on the first antenna 120, the second antenna 130 and the target processor 110, the whole formed by the coated yarn, the first antenna 120, the second antenna 130 and the target processor 110 is a functional yarn. The functional yarn can perform corresponding functions through the internal target processor 110. In addition, the functional yarn can be woven on a fabric like ordinary yarn.
[0062] It can be understood that by connecting the first antenna 120 to the first target pin of the target processor 110, the first antenna 120 can be used as the antenna of the target processor 110 to transmit signals to the target processor 110. However, due to the requirements of thinness and softness of the yarn, the first antenna 120 is usually set to be very thin, which affects its bandwidth.
[0063] Here, the second antenna 130 and the first antenna 120 are configured to form a loop, and a wide bandwidth antenna can be provided.
[0064] It should be understood that, since one end of the second antenna 130 is connected to one first antenna 120, and the other end is connected to another first antenna 120 or the second target pin of the target processor 110, a ring is formed between the second antenna 130 and the two first antennas 120, or a ring is formed between the second antenna 130 and the first antenna 120 and the target processor 110. The antenna with a ring structure can increase the bandwidth of the antenna, thereby improving the communication performance and flexibility of the first antenna 120.
[0065] In the above implementation process, by directly integrating the target processor 110 into the coated yarn, the functional yarn manufacturing process is simplified and the integration efficiency is improved. Moreover, this direct integration method can directly combine the functional yarn with the existing weaving and embroidery process, and weave the functional yarn into the fabric, thereby reducing production costs and improving production efficiency. In addition, by setting a second antenna 130, and the second antenna 130 is connected to the two first antennas 120, or the second antenna 130 is connected to the first antenna 120 and the second target pin of the target processor 110, the first antenna 120 and the second antenna 130 can form a ring structure, thereby increasing the bandwidth of the first antenna 120, forming a wide-bandwidth antenna, thereby improving data transmission efficiency, enhancing communication flexibility, and improving communication quality.
[0066] In one possible implementation, Figure 2-Figure 3 As shown, the plurality of first antennas 120 form at least one dipole antenna.
[0067] The dipole antenna here refers to an antenna structure composed of a pair of symmetrically placed conductors. The dipole antenna can be used as both a transmitting antenna and a receiving antenna.
[0068] When the dipole antenna is used as a transmitting antenna, the electrical signal is transmitted from the target processor 110 to the external receiver through the dipole antenna; when the dipole antenna is used as a receiving antenna, the electrical signal is transmitted from the external transmitter to the target processor 110 through the dipole antenna.
[0069] In one embodiment, one end of each second antenna 130 is connected to one of the first antennas 120 in the dipole antenna, and the other end of the second antenna 130 is connected to another of the first antennas 120 in the dipole antenna.
[0070] Here, the first antenna 120 and the second antenna 130 form a loop, thereby improving the antenna with a wide bandwidth.
[0071] Each of the above-mentioned dipole antennas is correspondingly configured with a second antenna 130 .
[0072] In the above implementation process, since the dipole wire has omnidirectional radiation characteristics and is easy to match and integrate, in the case where there are multiple first antennas 120, the first antenna 120 is set as a dipole antenna, which can increase the radiation performance of the first antenna 120, while reducing the structure of the first antenna 120, thereby reducing the difficulty of matching and integration of the first antenna 120. In addition, the two ends of the second antenna 130 are respectively connected to the two first antennas 120 in the dipole antenna to form a ring, thereby providing a wide-bandwidth antenna, improving data transmission efficiency, enhancing communication flexibility, and improving communication quality.
[0073] In one possible implementation, Figure 4-Figure 6 As shown, the dipole antenna is a bent dipole antenna ( Figure 6 and / or the dipole antenna is a linear dipole antenna ( Figure 4 , Figure 5 ).
[0074] The curved dipole antenna configuration is that the first antenna 120 is disposed on the target processor 110 in a curved shape, and the linear dipole antenna configuration is that the first antenna 120 is disposed on the target processor 110 in a linear shape.
[0075] Optionally, the bent dipole antenna may be a bent arm dipole antenna or an induction loop dipole antenna. The structure of the bent dipole antenna may be selected according to actual conditions.
[0076] The linear dipole antenna may be a first antenna 120 ( Figure 4 ), it can also be a straight line first antenna 120 ( Figure 5 The structure of the linear dipole antenna can be selected according to actual conditions.
[0077] It can be understood that in order to improve the connection strength between the first antenna 120 and the target processor 110 , the contact area between the first antenna 120 and the target processor 110 may be increased as much as possible.
[0078] For example, Figure 4 , Figure 5As shown, when the dipole antenna is a linear dipole antenna, one end of the two first antennas 120 in the dipole antenna connected to the target processor 110 is laid linearly on the surface of the target processor 110 and connected to pins relatively far away from the first antennas 120 .
[0079] like Figure 6 As shown, when the dipole antenna is a bent dipole antenna, one end of the two first antennas 120 in the dipole antenna connected to the target processor 110 is laid on the surface of the target processor 110 in a bent shape.
[0080] The shape of the above-mentioned dipole antenna is only exemplary, and the shape of the dipole antenna can be adjusted according to actual conditions.
[0081] The following uses the above three shapes of dipole antennas as examples to test the parameter changes of dipole antennas of different shapes:
[0082] First, a 50μm wire can be used for testing. Figure 7 (b)( Figure 7 (b) shows the variation of the reading distance of the dipole antenna with different shapes designed with a 50 μm wire as a function of frequency) It can be seen that the change of configuration will lead to an increase in the actual reading distance. Figure 7 (c)( Figure 7 (c) shows the variation of the reading distance of the dipole antennas of different shapes designed with 80μm wire as a function of frequency. The same variation trend is also observed with the 80μm wire. Figure 7 (b) and Figure 7 (c) It can be seen that compared with the antennas of the other two shapes, the linear antenna has a larger working bandwidth. Therefore, in the actual preparation process, dipole electrons with loop or linear patterns can be designed according to needs.
[0083] In the above implementation process, by shaping the first antenna 120 in the functional yarn into different geometric shapes, a variety of dipole antennas (such as curved dipole antennas and / or straight dipole antennas) can be formed, which can improve the performance and effect of the first antenna 120, optimize the signal reception and transmission efficiency of the first antenna 120, improve the accuracy and stability of the target controller, optimize the signal reception and transmission efficiency, and improve the recognition accuracy and stability of the functional yarn. In addition, different types of functional yarns can be set according to different application requirements to increase the flexibility of the functional yarn, which can be applied to various textile materials and application scenarios, and increase the application range and applicability of the functional yarn.
[0084] In a possible implementation, the first antenna 120 is connected to the first target pin by welding; and / or the second antenna 130 is connected to the first antenna 120 or the second target pin by welding.
[0085] It can be understood that in order to improve the flexibility of the first antenna 120 and the second antenna 130 after welding, welding is performed only at the connection between the first antenna 120, the second wire and the target controller. That is, by reducing the welding material attached to the first antenna 120 and the second antenna 130, the influence of welding on the flexibility of the first antenna 120 and the second antenna 130 is avoided.
[0086] For example, when welding the first antenna 120 and the target controller, welding material is placed only in the first pin, thereby reducing the welding material attached to the first antenna 120. For another example, when welding the second antenna 130 and the target controller, welding material is placed only in the second pin, thereby reducing the welding material attached to the second antenna 130, etc. The above-mentioned setting position of the welding material is only exemplary, and the setting position of the welding material can be selected according to actual conditions.
[0087] Optionally, welding can be performed using low-temperature solder paste or solder. The welding method in the embodiment of the present application can be selected according to actual conditions.
[0088] In one embodiment, the portion where the first antenna 120 is welded to the first target pin is a bare wire, and / or the portion where the second antenna 130 is welded to the first antenna 120 and the second target pin is also a bare wire.
[0089] Optionally, the welding methods of the first antenna 120 and the second antenna 130 may be the same or different. The welding methods of the first antenna 120 and the second antenna 130 may be selected according to actual conditions.
[0090] It is understandable that before welding the first antenna 120 to the target controller, the insulating paint on the surface of the first antenna 120 may be removed by molten solder, and a layer of tin may be plated at the position where the insulating paint is removed.
[0091] Exemplarily, the processing process of the first antenna 120 before being welded to the target controller can be as follows: heat the soldering pen to the target temperature (e.g., 350°C), heat the prepared solder to a molten ball through the soldering pen and hang it on the tip of the soldering pen, and place one end of the enameled wire to be welded into the molten solder. As the enameled wire moves, the insulating paint on its surface will be removed and attached to the surface of the molten solder, and the part inside the molten solder will be coated with a layer of tin.
[0092] Optionally, the second antenna 130 may also be processed according to the above steps before being welded to the first antenna 120 or the second target pin, which will not be described in detail here.
[0093] It should be understood that in the field of yarn production, the first antenna 120 and the target controller, and / or the second antenna 130 and the first antenna 120 or the target controller are often bonded by a glue material. Since the functional yarns usually need to be woven on fabrics, and the fabrics usually need to be cleaned, wound, etc., this method of connecting components by gluing will break or fall off during the cleaning and winding of the fabrics, and its water resistance and wear resistance are poor. Connecting components by welding has better firmness and shock resistance because welding can form a larger contact area on the connection surface.
[0094] In addition, since adhesive connections usually rely on various colloid products, which may cause skin discomfort and even allergies when in contact with the skin, using this functional yarn in fabrics may affect the user experience. Connecting various components by welding can reduce the use of colloid substances in functional yarns, reduce the discomfort of contact between colloid materials and skin, and enhance user experience.
[0095] In the above implementation process, welding can form a larger contact area on the connection surface compared to other connection methods, and has better firmness and shock resistance. By welding the first antenna 120 to the first target pin, and / or welding the second antenna 130 to the first antenna 120 or the second target pin, the connection strength between the first antenna 120 and the target processor 110, and / or the connection strength between the second antenna 130 and the first antenna 120 and the target processor 110 is increased. In addition, by welding the antennas, the use of glue and colloid adhesives in the functional yarn can be reduced, and the discomfort caused by the contact between the colloid material and the skin when the functional yarn is used on fabric can be reduced, thereby enhancing the user experience.
[0096] In one possible implementation, Figure 8 As shown, the surface of the target processor 110 is coated with an adhesive 140 .
[0097] The adhesive 140 here is a substance that can stick two or more objects together, such as black glue, epoxy resin, etc. The adhesive 140 can be selected according to actual conditions.
[0098] The adhesive 140 is configured to wrap the connection points between the first antenna 120 , the second antenna 130 and the target processor 110 .
[0099] It is understandable that, since the functional yarn can be woven on the fabric, the functional yarn will inevitably be folded, washed, rubbed, etc. during the weaving process or after the fabric is formed. Since the waterproof and rubbing resistance of the wrapped yarn is poor, if only the connection points of the first antenna 120, the second antenna 130 and the target processor 110 are wrapped by the wrapped yarn, when the above actions are performed on the functional yarn, the corresponding actions are performed directly on these connection points, which may cause the connection points to break and affect the connection effect.
[0100] By applying adhesive 140 on the surface of target processor 110, the adhesive 140 can wrap the target processor 110 and the connection points between the first antenna 120, the second antenna 130 and the target processor 110 inside. When the functional yarn is folded, washed, rubbed, etc., the target processor 110 and the connection points between the first antenna 120, the second antenna 130 and the target processor 110 located inside the adhesive 140 can reduce the execution of the above actions under the protection of the adhesive 140, thereby improving the connection effect between the first antenna 120, the second antenna 130 and the target processor 110.
[0101] In the above implementation process, by setting the adhesive 140, the adhesive 140 can wrap the target processor 110 and the connection points between the first antenna 120, the second antenna 130 and the target processor 110 inside, thereby reinforcing the connection points between the first antenna 120, the second antenna 130 and the target processor 110, thereby improving the connection stability between the first antenna 120, the second antenna 130 and the target processor 110.
[0102] In one possible implementation, Fig. 9 As shown, the target processor 110 is surrounded and filled with a thermosetting polymer material 150 to achieve a yarn hammer-shaped packaging for the target processor 110 .
[0103] The thermosetting polymer material 150 here refers to a polymer material that solidifies to form an irreversible three-dimensional network structure after heating, such as epoxy resin, phenolic resin, thermosetting polyimide, etc. The thermosetting polymer material 150 can be selected according to actual conditions.
[0104] In one embodiment, the target processor 110 coated with the adhesive 140 can be placed in a shuttle-shaped mold, and the shuttle-shaped mold can be filled with melted thermosetting polymer material 150. The thermosetting polymer material 150 is cured in the shuttle-shaped mold and then taken out, so that the hammer-shaped packaging of the target processor 110 can be achieved.
[0105] It should be understood that the target controller, the first antenna 120 and the second antenna 130 are susceptible to the shear force caused by the yarn wrapping during the yarn wrapping, which may cause the first antenna 120 and / or the second antenna 130 to be broken. By packaging the target controller and the first antenna 120 and the second antenna 130 around it in a yarn hammer shape, the influence of the shear force on the target controller, the first antenna 120 and the second antenna 130 can be reduced, and the stability and safety of the first antenna 120 and the second antenna 130 can be improved.
[0106] It can be understood that the target processor 110 can be a chip, a microprocessor, etc. Therefore, the obtained functional yarn can be used in different functional systems.
[0107] For example, the functional yarn is used in a body temperature monitoring system. The body temperature monitoring system includes three parts: a mobile device, a reader and a tag. The working principle of the body temperature monitoring system can be: the tag obtains radio frequency energy from the reader, and the reader recognizes the temperature measurement module information and displays the temperature measurement information on the mobile device in real time via Bluetooth. Among them, the functional yarn in the embodiment of the present application can be used as a tag.
[0108] If the body temperature monitoring system needs to be applied to clothing, the tag can be made into a rope shape first. Then, the tag can be sewn on the clothing using traditional sewing technology, and then the corresponding temperature can be read by the reader and the temperature information can be transmitted to the mobile device via Bluetooth. In addition, according to different needs, the tag can be sewn on different parts of the clothing to achieve body temperature detection in different parts. In addition, multiple tags can be set on the clothing to detect the body temperature of multiple parts at the same time.
[0109] In the above implementation process, by packaging the target processor 110 in a bobbin shape, the influence of shear force on the target controller, the first antenna 120 and the second antenna 130 can be reduced, thereby improving the stability and safety of the first antenna 120 and the second antenna 130.
[0110] like Fig.10 As shown, Fig.10 The functional yarn preparation method in the embodiment of the present application is shown, which is applied to prepare the functional yarn in the above embodiment, and the method comprises:
[0111] Step S201, connecting a first target pin of a target processor to one end of a first antenna; and connecting a second antenna to the first antenna and / or a second target pin of the target processor.
[0112] The first antenna and the second antenna here can be enameled wire, conductive yarn, etc. The first antenna and the second antenna can be selected according to actual conditions.
[0113] In one embodiment, if the first antenna and / or the second antenna is an enameled wire, before step S201, the method may further include:
[0114] like Fig.11 As shown, the soldering pen is heated to the target temperature (e.g., 350°C), the prepared solder is heated to a molten ball by the soldering pen and hung on the tip of the soldering pen, one end of the enameled wire to be welded is placed into the molten solder, and as the enameled wire moves, the insulating paint on its surface will be removed and attached to the surface of the molten solder, and the part inside the molten solder will be plated with a layer of tin. The tinned end is cut so that the part of the enameled wire without the insulating paint fits the first target pin, or the part of the enameled wire without the insulating paint fits the second target pin.
[0115] After processing the enameled wire, align the tinned end of the enameled wire with the first target pin of the target controller; and / or align the tinned end of the enameled wire with the second target pin of the target controller; and / or align the tinned end of the enameled wire with a point of another enameled wire.
[0116] After all points to be connected are aligned, a first target pin of a target processor is connected to one end of a first antenna through corresponding connecting materials; and a second antenna is connected to a second target pin of the first antenna and / or the target processor.
[0117] Optionally, the connection method may be welding connection, adhesive connection, clamping connection, etc., and the connection method of the first antenna may be the same as or different from the connection method of the second antenna. The connection method may be selected according to actual conditions.
[0118] For example, if the above-mentioned connection method is welding connection, step S201 can be implemented by the following steps:
[0119] Apply low-temperature solder paste to the first target pin, and place one end of the first antenna on the first target pin. Heat the low-temperature solder paste applied to the first target pin for a set heating time (e.g., 5 seconds to 10 seconds) and control it within a preset temperature range (e.g., about 300° C.), and complete the connection between the first antenna and the first target pin.
[0120] Similarly, low-temperature solder paste is applied to the second target pin, and one end of the second antenna is placed on the second target pin. The low-temperature solder paste applied to the second target pin is heated for a set heating time (e.g., 5 seconds to 10 seconds) and controlled within a preset temperature range (e.g., about 300° C.), completing the connection between the second antenna and the second target pin.
[0121] When connecting the second antenna to the first antenna, specific connection steps may be as follows:
[0122] Determine the location point where the first antenna is connected to the second antenna, and remove the insulating paint at the location point using a soldering pen (the specific removal method is the same as the above removal method, which will not be repeated here). Align the end of the second antenna connected to the first antenna with the location point, and place the molten solder ball hanging on the tip of the soldering pen at the location point. After the solder is dry, the connection between the first antenna and the second antenna is completed.
[0123] The above-mentioned connection method of the first antenna, the second antenna and the target processor is only exemplary, and the connection method of the first antenna, the second antenna and the target processor can be adjusted according to actual conditions.
[0124] Step S202, wrapping the coated yarn on the surface of the first antenna, the second antenna and the target processor to obtain the functional yarn.
[0125] The functional yarn here has a target processor inside and can execute the corresponding functions of the target processor.
[0126] Among them, the functional yarn can be woven on the fabric as ordinary yarn.
[0127] In one embodiment, the first antenna may include a variety of antenna shapes, such as a straight line shape, a curved line shape, etc. The antenna shape of the first antenna may be selected according to actual conditions.
[0128] The antenna shape configuration here refers to the shape of the first antenna on the target processor.
[0129] In the above implementation process, a functional yarn including a target processor can be made by connecting the target processor, the first antenna, and the second wire and wrapping them in a coated yarn. Since the target processor and the first antenna are provided in the functional yarn, the corresponding function of the target processor can be executed. In addition, by wrapping the coated yarn on the surface of the first antenna, the second antenna and the target processor, the functional yarn can be made into the appearance of ordinary yarn, and then can be woven on the fabric. On the one hand, the production cost of the functional yarn can be reduced. On the other hand, directly integrating the target processor into the coated yarn can make the target processor have better durability, reduce the risk of the target processor falling off, increase the application scenarios of the functional yarn, and improve the durability and flexibility of the functional yarn.
[0130] In a possible implementation, before step S201, the method further includes: determining a bandwidth corresponding to the first antenna of each antenna shape; and determining that, among one or more antenna shapes that meet the bandwidth condition, the antenna structure having the largest contact area between the first antenna and the target processor is the target antenna shape.
[0131] The bandwidth corresponding to the first antenna of each antenna shape can be determined through a set test experiment.
[0132] The target antenna shape here refers to the antenna shape of the final first antenna made into the functional yarn.
[0133] It should be understood that for each type of target processor, one or more corresponding antenna shapes can be set. When making functional yarn, the bandwidth corresponding to various antenna shapes corresponding to the target processor can be tested first to select antenna shapes that meet the bandwidth conditions. Then, the antenna structure with the largest contact area between the first antenna and the target processor among the selected antenna shapes is compared as the final antenna shape to be made.
[0134] In one embodiment, connecting a first target pin of a target processor to one end of a first antenna includes: connecting the first antenna to the first target pin according to a shape of the target antenna.
[0135] In the above implementation process, by determining the shape of the target antenna according to the bandwidth of the first antenna and the contact area between the first antenna and the target processor, the signal transmission capability of the first antenna can be improved. On the other hand, the connection strength between the first antenna and the target processor can be improved, and the wear resistance of the functional yarn can be improved.
[0136] In one possible implementation, before the first antenna, step S202, the method further includes: applying an adhesive on the surface of the target processor; when the adhesive is dry, placing the target processor in a shuttle-shaped mold; filling the shuttle-shaped mold with a liquid thermosetting polymer material; and removing the target processor from the shuttle-shaped mold after the thermosetting polymer material is cured.
[0137] The adhesive here is configured to wrap around connection points on the target processor.
[0138] In order to shorten the adhesive drying time, the adhesive can be dried in the following manner: the target processor coated with the adhesive is placed in a drying oven at a set temperature (eg, 130° C.) for a set drying time (eg, 30 minutes) to solidify the adhesive.
[0139] It should be understood that after the adhesive dries, the target processor can be placed in a shuttle-shaped mold, and the liquid thermosetting polymer material obtained by heating can be filled in the shuttle-shaped mold. The target processor can be wrapped by the thermosetting polymer material. After the thermosetting polymer material is solidified, the target processor can be taken out of the mold to achieve a yarn hammer-shaped package for the target processor.
[0140] After the target processor is packaged, the first antenna, the second antenna and the target processor can be wrapped with the covering yarn to obtain strands of braidable functional yarn.
[0141] Among them, the functional yarn can be woven into the fabric through traditional weaving techniques, embroidery techniques and other techniques.
[0142] In the above implementation process, by setting an adhesive, the adhesive can wrap the target processor and the connection points between the first antenna, the second antenna and the target processor, thereby reinforcing the connection points between the first antenna, the second antenna and the target processor, and improving the connection stability between the first antenna, the second antenna and the target processor. In addition, by encapsulating the target processor in a yarn hammer shape, the influence of shear force on the target controller, the first antenna and the second antenna can be reduced, and the stability and safety of the first antenna and the second antenna can be improved.

[0147] The connecting device is further used to connect the second antenna to the first antenna and / or a second target pin of the target processor.
[0148] The wrapping device is used for wrapping the coated yarn on the surface of the first antenna, the second antenna and the target processor to obtain the functional yarn.
[0149] The above-mentioned clamping device can be used to obtain action instructions and perform corresponding actions according to the corresponding action instructions. The clamping device can be a manipulator, a clamping claw, etc., and the clamping device can be selected according to actual conditions.
[0150] The connecting device here can be used to connect different components. For example, the connecting element can be a soldering pen, a spot applicator, etc. The connecting device can be selected according to actual conditions.
[0151] In one embodiment, the functional yarn preparation system may further include a platform. The platform is used to place the target controller.
[0152] It should be understood that when connecting the first antenna, the second antenna and the target controller, the target controller may be placed on the platform first.
[0153] A groove matching the shape of the target controller may be provided on the platform, and the target controller may be placed in the groove.
[0154] The wrapping device is used to wrap the coated yarn on the surface of the first antenna, the second antenna and the target processor. The wrapping device can be a rocker device, an automatic pay-off device, etc. The wrapping device can be selected according to actual conditions.
[0155] In the above implementation process, the wrapping device, the clamping device and the connecting device are provided to realize the automatic production of the functional yarn, thereby reducing the number of staff required for the production of the functional yarn and reducing the labor cost.
