Description
TECHNICAL FIELD
[0001] The utility model relates to a radio frequency identification (RFID) field, concretely relates to a carrier for radio frequency identification label. BACKGROUND
[0002] The tag and the reader are the main components of the radio frequency identification system, and the radio frequency signal is transmitted between the tag and the reader through the antenna in the tag. The tag is composed of an antenna and an IC chip, and serves a specific application. In the RFID system, the antenna is the bridge and link of communication. The efficiency and reliability of the wireless communication line between the RFID tag and the surrounding environment directly depend on the antenna. At the same time, the difficulty of the RFID system design is more concentrated in the tag antenna, especially in the antenna circuit design. For the RFID tag applied to the special scene of individualization and small-scale customization, the antenna design is particularly important. The design of the ultra-high frequency RFID tag needs to meet the requirements of antenna miniaturization, low cost, wide frequency band, etc. However, in order to match the chip impedance, the use of additional lumped elements usually makes the design large, so it is necessary to explore new matching technology to make the electronic tag design more compact. When the geometric shape of the antenna is designed to successfully reduce the antenna size factor, the radiation efficiency of the antenna will be affected and reduced, that is, researchers always have difficulty in reducing the size of the tag while ensuring the performance of the tag. How to design a suitable antenna for the electronic tag in a specific application through new matching technology and new strategy of reducing the size of the tag is the main means.
[0003] According to the difference of the antenna type, the manufacturing process of the RFID tag mainly includes the coil winding method, the etching method and the printing method.
[0004] When the coil winding method is used to manufacture the RFID tag antenna, the tag coil is wound on a winding tool and fixed, and the number of turns of the antenna coil is required to be more, and the coil can be a circular ring or a rectangular ring. This processing method has high cost, low production efficiency and poor consistency of the processed products.
[0005] The etching method usually uses copper or aluminum to manufacture the antenna, and this method is close to the etching process of the flexible printed circuit board in production process. The electronic tag circuit manufactured by the etching method is fine, has low resistivity, good weather resistance and stable signal. However, the manufacturing procedure of this method is complicated and the production capacity is low.
[0006] The printed antenna is directly printed on the insulating substrate (or film) with conductive ink to form the antenna circuit. The main printing method has been expanded from silk screen printing to offset printing, flexographic printing, gravure printing and other manufacturing methods. Its characteristic is fast production speed, but due to the larger resistance of the circuit formed by the conductive ink, its application range is limited to a certain extent.
[0007] When the antenna is combined into a tag, necessary protection measures need to be taken to ensure that the antenna is not easily damaged. The carrier is a commonly used necessary component to ensure that the shape of the antenna does not change. However, the size of the carrier depends on the size of the antenna, and the carrier needs to be customized for each tag. Utility model content

[0034] Unlike an RFID reader, an RFID antenna is a passive device that receives power through an RFID reader. When the energy of an RFID reader is transmitted to an antenna, the antenna generates an RF field, and then the RF signal is transmitted to the nearby tags. The efficiency of the wave generated by an RFID antenna in a specific direction is called antenna gain. In short, the higher the gain, the stronger the RF field and the wider the range the antenna will have. An RFID antenna emits an RFID wave along a horizontal or vertical plane, which is described as the polarity of the antenna. If the RF field is a horizontal plane, it is described as horizontal linear, and the same principle applies to an RFID antenna that creates a vertical plane.
[0035] In the warehouse management project, the cost of the RFID antenna accounts for less than 1% of the total cost. But if the performance of the RFID antenna is poor due to the wrong selection for the sake of reducing the cost or other reasons, it will be easy to cause unstable reading, missed reading, string reading, reading failure and other problems in the process of laying out the RFID antenna. In this case, not only the cost will not be reduced, but also it will be increased several times. Therefore, it is particularly important to select the appropriate RFID antenna when deploying the RFID system.
[0036] The importance of the carrier for protecting the RFID tag is self-evident, but the carrier of each tag needs to be customized due to the difference in tag structure, which will increase the tag development process and cost. Therefore, in order to save development time and cost, a kind of RFID tag carrier element which can be combined with each other is designed.
[0037] Carrier element of the first embodiment
[0038] Figure 1a And Figure 1b The schematic perspective views of the opposite first surface and second surface of the carrier element 100 of the first embodiment of the present application are shown respectively.
[0039] As Figure 1a shown, the carrier element 100 has a base 110. One or more chip slots 101 for placing the chip of the RFID tag therein are formed on the first surface 110a of the base 110. On the first surface 110a of the base 110, the area other than the chip slots 101 is formed with a plurality of protrusions 103 arranged in an array on the first surface 110a of the base 110 and each protrusion 103 maintains a spacing therebetween. The spacing forms an antenna slot 105 for accommodating the metal antenna. It should be understood that although two chip slots 101 formed along the edge of the first surface 110a are shown in Figure 1a , the skilled person can form more chip slots in other positions (for example, the central area of the first surface 110a) or fewer chip slots on the first surface 110a in practice according to the needs. Preferably, the shape of each protrusion 103 can be set to have a rounded shape, for example, an oval shape.
[0040] Preferably, the spacing between the protrusions 103 is dimensioned to be suitable for accommodating and fixing the metal antenna of the RFID tag. Alternatively, each protrusion 103 in the array of protrusions 103 can have the same size. Or, the size of the protrusions in the array of protrusions 103 can vary regularly to be more suitable for matching the impedance of the RFID chip. For example, as shown in the array of protrusions 103 on the first surface 110a of the base 110 in Figure 1a , the protrusions in the first and third rows have a shorter width, while the protrusions in the second row have a longer width. The skilled person should understand that Figure 1a the width of the protrusions shown in is only an example and is not limiting, and in practice, the skilled person can adjust the size of the protrusions according to the desired impedance characteristics.
[0041] Figure 1bAs shown, a plurality of protrusions 104 are formed on a second surface 110b of the base 110 opposite the first surface 110a in an array. The shape and size of the protrusions 104 on the second surface 110b are set similarly to the shape and size of the protrusions 103 on the first surface 110a, and thus will not be described again here. In addition, although not shown in FIG. 1, optionally, a chip slot for seating a chip can also be formed on the second surface 110b of the base 110. In the case of having a chip slot, the array of protrusions 104 can be formed on the region of the second surface 110b other than the chip slot, and in the case of not having a chip slot, the array of protrusions 104 can be formed on the entire second surface 110b. Figure 1b
[0042] One end of the base 110, which is referred to as a convex end 110c of the base 110, can be formed with a convex portion 106, and the other end, which is referred to as a concave end 110d of the base 110, can be formed with a concave portion 107. The shape and size of the convex portion 106 can correspond to the shape and size of the concave portion 107, such that the convex portion 106 of one base can be inserted into and fastened in the concave portion 107 of another base. Thereby, the size of the carrier can be expanded in the length direction (x-axis direction) of the base 110.
[0043] In addition, preferably, the upper side 110e and the lower side 110f of the base 110 can be formed with corresponding one or more mating members 108, such as a positioning pin and a hole. For example, the upper side 110e can be formed with one or more positioning pins, and the lower side 110f can be formed with one or more holes corresponding to the positioning pins, such that the positioning pin of one base can be inserted into and fastened in the hole of another base. Thereby, the size of the carrier can be expanded in the width direction (y-axis direction) of the base 110. It should be understood that the upper side or the lower side of the base can be formed with different types of mating members at the same time, such as a positioning pin and a hole at the same time, as long as the shape of its mating member can correspond to the shape of the mating member of one side of another base to mate with each other. In addition, the shape of the mating member on one side can be symmetric or centrosymmetric along the central axis in the length direction, such that when two bases are combined in different front combinations (as shown in FIG. 2), their mating members can still mate with each other. Figure 2a
[0044] Furthermore, preferably, one or both of the leading edge and the trailing edge in the y-axis direction can be formed with a protruding edge 109 on the first surface 110a and the second surface 110b of the base 110 depending on the extension direction of the carrier (i.e. the combined direction of the carrier elements 100), thereby protecting the label structure mounted on the carrier from external force. To this end, the height of the protruding edge 109 can be greater than the height of the label structure on the carrier. Among them, the leading edge 111 of the first surface 110a refers to the edge of the first surface 110a adjacent to the lower side 110f, the trailing edge 112 of the first surface 110a refers to the edge of the first surface 110a adjacent to the upper side 110e, the leading edge 113 of the second surface 110b refers to the edge of the second surface 110b adjacent to the lower side 110f, and the trailing edge 114 of the second surface 110b refers to the edge of the second surface 110b adjacent to the upper side 110e. Specifically, in the case of combining the carrier elements 100 along the y-axis direction (as shown in the subsequent Figure 2a ), the protruding edge 109 can be formed only on the trailing edge of the first surface 110a and the trailing edge of the second surface 110b of the base 110; while in the case of combining the carrier elements 100 along the x-axis direction (as shown in the subsequent Figure 3a ), the protruding edge 109 can be formed on both the leading edge and the trailing edge of the first surface 110a and the leading edge and the trailing edge of the second surface 110b of the base 110.
[0045] <Combination of carrier elements of the first embodiment>
[0046] Figure 2a A schematic exploded view of combining the carrier elements of the first embodiment of the present application along the width direction (y-axis direction) is shown. As shown in Figure 2a , the carrier assembly 200 includes a first carrier element 210 and a second carrier element 220, and the first carrier element 210 and the second carrier element 220 are combined together along the width direction (y-axis direction). Among them, the first carrier element 210 has the first surface facing the +z-axis direction as the front surface and its lower side facing the +y-axis direction, while the second carrier element 220 has the second surface facing the +z-axis direction as the front surface and its lower side facing the -y-axis direction, and the mating part of the lower side of the first carrier element 210 and the mating part of the lower side of the second carrier element 220 mate with each other. In this embodiment, the protruding edge is only formed on the trailing edge of the first surface and the second surface of the base of the first carrier element 210 and the second carrier element 220 (the edge of the first surface and the second surface adjacent to the upper side), and by the aforementioned combination manner, the protruding edge only exists on the edge of the combined carrier assembly 200 and does not exist in the interior of the carrier assembly 200. Thereby, the label structure on the carrier can be protected from external force while preventing the protruding edge from hindering the arrangement of the metal antenna.
[0047] ByFigure 2a The combination shown enables the expansion of the carrier size in the width (y-axis) direction. However, those skilled in the art will recognize that the first carrier element 210 and the second carrier element 220 can be combined with any frontal configuration as needed for the RFID chip location. For example, both the first carrier element 210 and the second carrier element 220 can have the first surface as their frontal configuration, or the first surface and the second surface can be used as their frontal configurations respectively.
[0048] Figure 2b It shows that Figure 2a The carrier assembly 200 is shown as a top view of the RFID tag as a carrier, with one arrangement of the RFID tag's metal antenna shown in solid lines and another arrangement shown in dashed lines. The RFID tag's chip 230 is disposed in a chip slot adjacent to the trailing edge of the first carrier element 210, and the metal antenna extends from both sides of the chip. The wiring of the metal antenna is designed to match the chip impedance.
[0049] Figure 3a A schematic exploded view of the carrier elements of the first embodiment of the present invention, arranged along the length direction (x-axis direction), is shown. The antenna carrier assembly 300 includes a first carrier element 310 and a second carrier element 320, which are combined together along the length direction (x-axis direction). The first carrier element 310 is arranged with its first surface facing forward and the second carrier element 320 with its second surface facing forward, and the protrusion 327 of the second carrier is embedded in and secured within the recess 318 of the first carrier element 310. Furthermore, preferably, the leading and trailing edges of the first surfaces and the leading and trailing edges of the second surfaces of the bases of the first carrier element 310 and the second carrier element 320 are formed with protruding edges to protect the label structure on the carrier.
[0050] pass Figure 3a The combination shown enables the antenna carrier size to be extended in the length (x-axis) direction. However, those skilled in the art will recognize that the first carrier element 310 and the second carrier element 320 can be combined in any frontal configuration as needed for the RFID chip location.
[0051] Figure 3b It shows that Figure 3a The carrier component 300 serves as the carrier for the RFID tag, with one arrangement of the RFID tag's metal antenna shown in solid lines and another arrangement shown in dashed lines. The RFID tag's chip 330 is disposed in a chip slot adjacent to the trailing edge of the first carrier element 310, and the metal antenna extends from both sides of the chip. The wiring of the metal antenna is designed to match the chip impedance.
[0052] <Carrier element and combination thereof of the second embodiment>
[0053] Figure 4 A schematic perspective view of a carrier element and combination thereof of a second embodiment of the present application is shown. The carrier assembly 400 comprises a first carrier element 410 and a second carrier element 420, wherein the first carrier element 410 and the second carrier element 420 are combined together along the height direction (z-axis direction). The structure of the first carrier element 410 and the second carrier element 420 is similar to that of the carrier element 100 of the first embodiment described above, which will not be repeated here. In this embodiment, the first carrier element 410 is combined with the second carrier element 420 with the first surface as the front face facing the +z-axis direction and the second surface as the front face facing the +z-axis direction. However, it will be appreciated by those skilled in the art that the second carrier element 420 can also be combined with the first carrier element 410 with the first surface as the front face facing the +z-axis direction. In addition, preferably, the surfaces of the base of the first carrier element 410 and the second carrier element 420 forming the outer surface of the carrier assembly 400 (in the embodiment shown, the front edge and the rear edge of the first surface of the first carrier element 410 and the first surface of the second carrier element) are formed with a protruding edge to protect the label structure on the carrier. Figure 4 In the embodiment shown, both the front edge and the rear edge of the first surface of the first carrier element 410 and the first surface of the second carrier element are formed with a protruding edge to protect the label structure on the carrier. Alternatively, both the front edge and the rear edge of the first surface and the second surface of the first carrier element 410 and the first surface and the second surface of the second carrier element 420 are formed with a protruding edge to protect the label structure on the carrier.
[0054] The first carrier element 410 and the second carrier element 420 can be combined and fixed to each other by various fixing members. As an example, after the first carrier element 410 and the second carrier element 420 are placed along the height direction, the first carrier element 410 and the second carrier element 420 can be fixed together by embedded fixing members 401 (e.g., bolts, pins, etc.). Additionally or alternatively, the first carrier element 410 and the second carrier element 420 can be fixed together by external fixing members (not shown in the figure) such that the first carrier element 410 and the second carrier element 420 do not move relative to each other. For example, after the first carrier element 410 and the second carrier element 420 are placed along the height direction, a "sun" shaped fixing member can be nested around the periphery of the first carrier element 410 and the second carrier element 420, and the inner periphery of the "sun" shaped fixing member can match (e.g., match in width and length or match in shape) the outer periphery of the first carrier element 410 and the second carrier element 420.
[0055] By way of example, Figure 4The size of the antenna carrier in the height (z-axis) direction can be expanded in the combination shown in FIG. 4. In an embodiment in which the carrier assembly 400 is used as a carrier of an RFID tag, the chip of the RFID tag can be disposed in the chip slot on the first surface of the first carrier element 410, and the metal antenna of the RFID tag can be extended along the antenna slot on the first surface of the first carrier element 410, around the side surfaces (e.g., the convex end 110c, the concave end 110d as described with reference to FIG. 1) of the first carrier element 410 and the second carrier element 420 to the first surface of the second carrier element 420 facing the -z-axis direction. By expanding the size of the antenna carrier in the height (z-axis) direction, the length of the metal antenna of the RFID tag can be further fine-tuned to achieve impedance matching of the RFID tag.
[0056] As another embodiment, the structures of the first carrier element 410 and the second carrier element 420 can be similar to the carrier element 100 of the first embodiment described above, but the second surface of the base of the first carrier element 410 is not formed with an array of protrusions, but is formed with an array of recesses, and preferably, the shape and position of the array of recesses on the second surface of the first carrier element 410 are set such that the array of recesses on the second surface of the first carrier element 410 can completely receive the array of protrusions on the first surface and the second surface of the second carrier element 420, thereby enabling the second carrier element 420 to be overlapped with the first carrier element 410 with the second surface of the second carrier element 420 facing the first surface or the second surface of the first carrier element 410, to expand the size of the antenna carrier in the height (z-axis) direction. In this embodiment, preferably, the leading edge and the trailing edge of the surfaces of the base of the first carrier element 410 and the second carrier element 420 forming the outer surface of the carrier assembly 400 (in the embodiment shown in FIG. 4, the first surface of the first carrier element 410 and the first surface of the second carrier element 420) are formed with a protruding rim to protect the tag structure on the carrier, while the surfaces of the first carrier element 410 and the second carrier element 420 within the carrier assembly 400 (in the embodiment shown in FIG. 4, the second surface of the first carrier element 410 and the second surface of the second carrier element 420) are not formed with a protruding rim, so that the second surface of the second carrier element 420 can be completely embedded in the second surface of the first carrier element.
