[0038] Reference below Figure 1-Figure 6 An anti-metal electronic tag 100 according to an embodiment of the present invention is described.
[0039] like Figure 1-Figure 3 As shown, an anti-metal electronic tag 100 according to an embodiment of the present invention includes: an electronic tag body 10 and a metal isolation piece 20. The electronic tag body 10 is suitable for being arranged on a device 30. The metal isolation piece 20 is connected to the electronic tag body 10 to isolate the electronic tag body 10 from the device 30, thereby blocking the influence of the surface of the device 30 on the reading distance of the electronic tag body 10.
[0040] According to the anti-metal electronic tag 100 of the embodiment of the present invention, by setting the metal isolation piece 20 on the electronic tag body 10, the metal isolation piece 20 can effectively block the influence of the surface of the device 30 on the reading distance of the electronic tag body 10, thereby ensuring that the anti-metal electronic tag 100 has good reading performance in different installation environments; thereby, the problem of large difference in the reading distance of the anti-metal electronic tag 100 caused by different metal materials on the surface of the device 30, the flatness of the metal material on the surface of the device 30 and the thickness of the metal material on the surface of the device 30 can be solved, so that the performance of the electronic tag body 10 can be maximized, and the production is convenient and simple, and the production cost is low.
[0041] Among them, the surface of the device 30 here can be a metal structure, and the electronic tag body 10 includes an injection molded core, an antenna, a radio frequency chip and a metal layer. The antenna and the radio frequency chip are assembled on one side of the injection molded core, and the metal layer is assembled on the other side of the injection molded core. The injection molded core here acts as a bracket and can limit the distance between the antenna and the metal layer. Therefore, the electronic tag body 10 can be set on a device with a metal structure on the surface, and cooperate with the metal surface to enhance the sensing ability of the radio frequency signal to the tag.
[0042] According to one embodiment of the present invention, the projection of the metal isolation member 20 on the plane where the antenna is located covers the antenna, thereby ensuring that the metal isolation member 20 effectively blocks the antenna from the device 30, preventing the material, curvature or flatness of the surface of the device 30 from affecting the antenna's recognition, thereby affecting the reading and application performance of the anti-metal electronic tag 100.
[0043] According to one embodiment of the present invention, if the thickness of the metal isolation member 20 is too large, it will easily lead to a large difference in the reading distance of the anti-metal electronic tag 100. If the thickness of the metal isolation member 20 is too small, it will not have an effective barrier effect, which will also affect the reading distance of the anti-metal electronic tag 100. Therefore, the thickness range of the metal isolation member 20 is limited to between 0.1mm-0.5mm, that is, the thickness of the metal isolation member 20 can be 0.1mm, 0.3mm, 0.5mm, etc., to ensure that under the action of the metal isolation member 20, the anti-metal electronic tag 100 has better reading and application performance.
[0044] According to an embodiment of the present invention, the metal spacer 20 and the electronic tag body 10 are connected together by injection molding, so that the metal spacer 20 and the electronic tag body 10 form an integral part, thereby facilitating the installation of the anti-metal electronic tag 100 on any device 30.
[0045] In the injection molding process of the anti-metal electronic tag 100, the metal spacer 20 can be directly injection molded into the shell of the anti-metal electronic tag to form an integrated injection-molded anti-metal electronic tag with the metal spacer 20. At this time, the thickness of the metal spacer 20 can be relatively thin, for example, the thickness is 0.1 mm. The metal spacer 20 can be other metals such as aluminum foil and copper foil. Of course, in the injection molding process of the anti-metal electronic tag 100, the metal spacer 20 can also be injection molded outside the shell of the electronic tag body 10. At this time, the thickness of the metal spacer 20 can be appropriately increased, for example, the thickness is 0.4 mm, so as to facilitate the assembly of the metal spacer 20 without affecting the reading distance of the electronic tag body 10.
[0046] According to one embodiment of the present invention, the metal isolation member 20 is fastened to the electronic tag body 10. For example, the metal isolation member 20 may be a steel plate. The metal isolation member 20 has a slot and the electronic tag body 10 has a buckle. Alternatively, the metal isolation member 20 has a buckle and the electronic tag body 10 has a slot. The buckle and the slot are matched to connect the two, so that the metal isolation member 20 and the electronic tag body 10 are not easily separated, thereby facilitating the installation of the anti-metal electronic tag 100 on any device 30.
[0047] According to one embodiment of the present invention, the metal isolation member 20 includes an isolation portion 21, which is suitable for being clamped between the electronic tag body 10 and the device 30, and the shape of the isolation portion 21 corresponds to the shape of the electronic tag body 10. By making the isolation portion 21 correspond to the shape of the electronic tag body 10, it is convenient for the isolation portion 21 to cooperate with the electronic tag body 10, and it can also ensure that the isolation portion 21 can play an effective barrier effect.
[0048] The isolating portion 21 forms an isolating plate with a flat surface, and the electronic tag body 10 cooperates with the isolating portion 21 to avoid the uneven surface of the isolating portion 21 affecting the reading distance of the electronic tag body 10, while facilitating assembly, connection or injection molding of the isolating portion 21 and the electronic tag body 10.
[0049] In some examples, if the thickness of the isolation portion 21 is too large, it may easily lead to a large difference in the reading distance of the anti-metal electronic tag 100. If the thickness of the isolation portion 21 is too small, it will not have an effective barrier effect, which will also affect the reading distance of the anti-metal electronic tag 100. Therefore, the thickness range of the isolation portion 21 is limited to between 0.1mm-0.5mm, that is, the thickness of the isolation portion 21 can be 0.1mm, 0.3mm, 0.5mm, etc., to ensure that under the action of the isolation portion 21, the anti-metal electronic tag 100 has better reading and application performance.
[0050] In some examples, an antenna is provided in the electronic tag body 10, and the projection of the isolation portion 21 on the plane where the antenna is located covers the antenna, thereby ensuring that the isolation portion 21 effectively blocks the antenna from the device 30, preventing the material, curvature or flatness of the surface of the device 30 from affecting the antenna recognition and affecting the reading and application performance of the anti-metal electronic tag 100.
[0051] In some examples, the isolation part 21 is connected to the electronic tag body 10 through an injection molding process. That is, in the production of the anti-metal electronic tag 100 by injection molding, the isolation part 21 can be directly injection molded into the shell of the anti-metal electronic tag to form an anti-metal electronic tag 100 with an isolation part 21. In this case, the isolation part 21 can be other metals such as aluminum foil and copper foil, and the thickness of the isolation part 21 can be 0.1mm. Of course, in the production of the anti-metal electronic tag 100 by injection molding, the isolation part 21 can also be injection molded outside the shell of the electronic tag body 10. In this case, the isolation part 21 can be a steel plate, and the thickness of the isolation part 21 can be 0.4mm.
[0052] like Figure 1 As shown, according to an embodiment of the present invention, the metal isolator 20 includes: an isolating portion 21 and an extending portion 22. The isolating portion 21 is suitable for being sandwiched between the electronic tag body 10 and the device 30. The isolating portion 21 forms an isolating plate with a flat surface. One end of the extending portion 22 is connected to the isolating portion 21, and the other end extends in a direction away from the electronic tag body 10. Under the action of the extending portion 22 and the isolating portion 21, the metal isolator 20 can wrap the electronic tag body 10 to a certain extent, further maximizing the performance of the electronic tag body 10.
[0053] In some specific examples, the angle between the extension portion 22 and the isolation portion 21 ranges from 90° to 180°, that is, the extension portion 22 can extend outward along the extension direction of the isolation portion 21, and the angle between the extension portion 22 and the isolation portion 21 is 180°. The extension portion 22 can also be arranged perpendicular to the isolation portion 21, and the angle between the extension portion 22 and the isolation portion 21 is 90°. Of course, the angle between the extension portion 22 and the isolation portion 21 can also be 120°, 145°, 150°, etc. Under the action of the extension portion 22, the electronic tag body 10 is half-wrapped to ensure that the performance of the electronic tag body 10 is maximized.
[0054] Among them, the extension part 22 may include one, or may include two or more, and the extension part 22 is located at any edge of the isolation part 21. That is to say, any edge of the isolation part 21 may be provided with an extension part 22, or may not be provided with an extension part 22. The angle between each extension part 22 and the isolation part 21 may be the same or different, so as to achieve the best performance of the electronic tag body 10.
[0055] like Figure 2 As shown, in some examples, the extension portion 22 includes two first extension portions 221 arranged opposite to each other, and the angle between the first extension portion 221 and the isolation portion 21 is 150°. Under the action of the two first extension portions 221, the side of the electronic tag body 10 is wrapped to ensure that the performance of the electronic tag body 10 is maximized.
[0056] In some examples, the extension portion 22 includes a plurality of extension portions 22, which are connected to each other to form a ring-shaped extension portion surrounding the electronic tag body 10, such as Figure 1 As shown, the outer side of the isolation portion 21 has two oppositely arranged first extension portions 221 and two oppositely arranged second extension portions 222, the angle between the first extension portion 221 and the isolation portion 21 is 150°, the angle between the second extension portion 222 and the isolation portion 21 is 180°, the first extension portion 221 and the second extension portion 222 are interconnected to form an annular extension portion, thereby improving the barrier effect of the metal isolation member 20 on the electronic tag body 10, ensuring that the performance of the electronic tag body 10 is maximized.
[0057] In some specific examples, the isolation portion 21 and the extension portion 22 are plate structures of equal thickness, and the thickness range is between 0.1mm-0.5mm, that is, the thickness of the metal isolation member 20 can be 0.1mm, 0.3mm, 0.5mm, etc., to ensure that under the action of the metal isolation member 20, the anti-metal electronic tag 100 has better reading and application performance.
[0058] The method for manufacturing an anti-metal electronic tag according to an embodiment of the present invention comprises the following steps:
[0059] S1, provides antenna and RF chip, metal layer, and injection molded core;
[0060] S2, providing metal isolation parts;
[0061] S3, assembling the antenna and the radio frequency chip, the metal layer, the injection molded inner core and the metal spacer to form an anti-metal electronic tag.
[0062] According to the manufacturing method of the anti-metal electronic tag of the embodiment of the present invention, the influence of the device surface on the reading distance of the electronic tag body can be effectively blocked, and an anti-metal electronic tag with good reading performance in different installation environments can be manufactured. The manufacturing is convenient and simple, and the production cost is low.
[0063] The injection molded inner core acts as a bracket and can also limit the distance between the antenna and the metal layer. Thus, the anti-metal electronic tag can be set on a device with a metal surface and cooperate with the metal surface to enhance the sensitivity of the radio frequency signal to the tag.
[0064] According to one embodiment of the present invention, assembling the antenna and the RF chip, the metal layer, the injection molded inner core and the metal spacer includes: assembling the antenna and the RF chip, the metal layer and the injection molded inner core into one piece by an injection molding process to form an electronic tag body with an injection molded shell; assembling the electronic tag body and the metal spacer to form an anti-metal electronic tag. Therefore, in the production of the anti-metal electronic tag injection molding process, the metal spacer is injection molded outside the shell of the electronic tag body.
[0065] Combine the following Figure 5 , describing a method for manufacturing an anti-metal electronic tag according to the present invention.
[0066] First, FPC plate making is carried out to make FPC antenna; printing or patch processing is carried out; the RF chip is welded on the FPC antenna through SMT welding and dispensing process; an injection molded core is provided; a metal layer is provided at the same time, and assembly is carried out so that the antenna and the RF chip are located on one side of the injection molded core, and the metal layer is located on the other side of the injection molded core, and then, the electronic tag body is formed by injection molding the outer shell; a finished metal spacer is provided; finally, the electronic tag body and the metal spacer are assembled to form an anti-metal electronic tag.
[0067] According to another embodiment of the present invention, assembling the antenna and the RF chip, the metal layer, the injection-molded inner core and the metal spacer includes: assembling the antenna and the RF chip, the metal layer, the injection-molded inner core and the metal spacer into one piece by an injection molding process to form an anti-metal electronic tag with an injection-molded shell. That is, in the injection molding process of the anti-metal electronic tag, the metal spacer can be directly injection-molded into the shell of the anti-metal electronic tag to form an integrated injection-molded anti-metal electronic tag with a metal spacer.
[0068] Combine the following Figure 6 , describing a method for manufacturing an anti-metal electronic tag according to the present invention.
[0069] First, FPC plate making is carried out to make FPC antenna; printing or patch processing is carried out; the RF chip is welded to the FPC antenna through SMT welding and dispensing process; an injection molded core is provided; then, a metal layer is provided, and a manufactured metal spacer is provided at the same time, and then assembly is carried out so that the antenna and the RF chip are located on one side of the injection molded core, the metal layer is located on the other side of the injection molded core, and the metal spacer is also located on the other side of the injection molded core, and finally an anti-metal electronic tag is formed through an injection molded shell.
[0070] Therefore, the manufactured anti-metal electronic tag can effectively block the influence of the device surface on the reading distance of the electronic tag body. Since each anti-metal electronic tag carries a unique asset identity code, it can identify the device and use radio frequency signals to transmit the device code, which can easily realize the full life cycle management of device assets.
