DETAILED DESCRIPTION
[0009] The following detailed features and advantages of the present invention are described in detail in the embodiments, and the content is sufficient to enable anyone skilled in the relevant art to understand the technical content of the present invention and implement it accordingly. According to the content disclosed in this specification, the scope of the patent application and the drawings, anyone skilled in the relevant art can easily understand the relevant purposes and advantages of the present invention. The following examples are to further illustrate the viewpoints of the present invention in detail, but are not intended to limit the scope of the present invention in any way.
[0010] Please refer to Figure 1 and 2 ,in Figure 1 is a three-dimensional exploded view of a wireless radio frequency identification device according to an embodiment of the present invention; Figure 2: is an example diagram of a radio frequency identification device according to an embodiment of the present invention. The radio frequency identification device (RFID) of this embodiment preferably includes a first component 1 and a second component 2. In detail, the first component 1 includes a radiation layer 11 and a first joint portion J1, and the radiation layer 11 forms a radiation pattern 110 (Radiation Pattern), that is, the outer periphery of the radiation layer 11 is surrounded to form the radiation pattern 110; the second component 2 includes a carrier 20, a loop antenna 21 (Loop Antenna), a chip 22 and a second joint portion J2, and the loop antenna 21, the chip 22 and the second joint portion J2 are disposed on the carrier 20 of the second component 2. In addition, the loop antenna 21 is electrically connected to the chip 22, and the second joint portion J2 is used to be detachably combined with the first joint portion J1. In addition, the radiation layer 11 and the loop antenna 21 are electromagnetically coupled to each other, and when the first joint portion J1 is combined with the second joint portion J2, the transmission distance of the combined first component 1 and the second component 2 will be longer than the transmission distance of the second component 2 itself. The radiation pattern 110 illustrated in the present invention is only an example, and the radiation pattern 110 may be different patterns according to factors such as different radiation ranges / distances, manufacturing methods, etc., and the present invention is not limited thereto.
[0011] Please continue to refer to Figure 2 , Figure 2 It is a wireless radio frequency identification device illustrated according to an embodiment of the present invention, wherein the chip 22 is electrically connected to the circular antenna 21, and the second component 2 itself has a first transmission distance, and the first component 1 and the second component 2 combined with the first joint portion J1 and the second joint portion J2 have a second transmission distance, and the second transmission distance is greater than the first transmission distance. In detail, the second transmission distance can be ten to forty times the first transmission distance. For example, if the first transmission distance is 5cm to 30cm, the second transmission distance can reach 50cm to 12m, so as long as the reader is within the second transmission distance, the reader can read the data stored in the chip 22 and / or write the data into the chip 22, or rewrite the data stored in the chip 22, and the present invention is not limited to this.
[0012] Please continue to refer to Figure 2The first joint portion J1 is preferably a part of the radiation pattern 110. For example, the middle section 110c connecting the two radiation ends 110a and 110b in the radiation pattern 110 is used as the first joint portion J1. The second joint portion J2 is preferably two clamping grooves extending inward from one side of the carrier 20 but not intersecting with the circular antenna 21. In detail, when the middle section 110c is placed in any clamping groove, the parts on both sides of the clamping groove will be reset in the opposite direction by the elasticity of the carrier 20 itself to clamp the middle section 110c, thereby completing the assembly structure in which the second joint portion J2 (clamping groove) is detachably combined with the first joint portion J1 (middle section 110c). However, the second joint portion J2 can be realized as long as it can be engaged with the first joint portion J1. The present invention is not limited to the number, position or shape of the second joint portion J2 (clamping groove). In addition, according to the wireless radio frequency identification device disclosed in this embodiment, part of the loop antenna 21 is preferably located between the chip 22 and the middle section 110c (eg Figure 2 As shown) to have a better transmission distance, the chip 22 can also be located between the middle section 110c and a portion of the circular antenna 21, but the present invention is not limited thereto.
[0013] In addition, please refer to Figure 3 If the overlapping area between the carrier 20 and the radiation pattern 110 is large (for example, Figure 3 As shown, the overlapping area of the carrier 20 and the radiation pattern 110 includes a portion of the radiation ends 110a and 110b), then the first connecting portion J1 can be a portion of the two radiation ends 110a and 110b of the radiation pattern 110, and the two clamping grooves serving as the second connecting portion J2 are respectively aligned with the first connecting portion J1 located at the two radiation ends 110a and 110b to be combined with the first connecting portion J1.
[0014] Please refer to Figure 4 , the second joint portion J2 may also be two clamping grooves extending inwardly from two different sides of the carrier 20, so that the first component 1 can be inserted into the two clamping grooves from different directions, thereby improving the stability of the combination between the first joint portion J1 and the second joint portion J2. In addition, as shown in FIG. 4, the two clamping grooves as the second joint portion J2 preferably extend inwardly from two opposite sides of the carrier 20, thereby making better use of the elasticity of the first component 1 itself to clamp the portion of the carrier 20 located between the two clamping grooves from two opposite directions (i.e., Figure 4 As shown, the portion located between the two clamping grooves and having the cyclic antenna 21).
[0015] Please refer to Figure 5-6 , Figure 5-6 is an example diagram of a wireless radio frequency identification device according to multiple embodiments of the present invention. Figure 5-6 The RFID device shown is similar to Figure 2-4 The wireless radio frequency identification device shown in the figure is similar to that shown in the figure, so the similarities are not described here in detail. Figure 5-6 The wireless radio frequency identification device shown is Figure 2-4 The differences between the ones shown are: Figure 5-6 The first joint portion J1' and the second joint portion J2' are different from Figure 2-4 The first joint portion J1 and the second joint portion J2, therefore Figure 5-6 The shape / size of the carrier 20' and the positions and forms of the first joint portion J1' and the second joint portion J2' can be Figure 2-4 The carrier board 20 is different. For example, Figure 6 In the illustrated carrier 20', any one of the two clamping grooves constituting a part of the second joint J2' may be T-shaped, that is, in addition to extending inward from one side of the carrier 20', the end of the clamping groove away from the side is bifurcated.
[0016] Please go back Figure 5 If the overlapping area of the carrier 20' and the radiation pattern 110 is larger, the second joint portion J2' is still two clamping grooves extending inward from two different sides of the carrier 20', but the width of each clamping groove is greater than the width of the middle section 110c, but less than the width of the radiation ends 110a, 110b. Thus, when the radiation layer 11 is inserted into the clamping groove, the portions of the carrier 20' located on both sides of the single clamping groove can be pressed against one side surface of the radiation layer 11 (the surface of the radiation ends 110a, 110b adjacent to the middle section 110c), and the portion of the carrier 20' located between the two clamping grooves is pressed against the other side surface of the radiation layer 11 (the surface of the middle section 110c). In other words, in this embodiment, the first joint portion J1' is the radiation ends 110a, 110b pressed against the surface of the carrier 20', and the middle section 110c pressed against the surface of the carrier 20'; and the second joint portion J2' is two clamping grooves extending inward from two different sides of the carrier 20'.
[0017] Please refer to Figure 6In this embodiment, the second joint portion J2' is not only two clamping grooves extending inward from two different sides of the carrier 20', but also includes two bifurcated slits formed at the ends of the two clamping grooves, thereby, any one of the two clamping grooves constituting a part of the second joint portion J2' can be in a "T" shape. The length of the bifurcated slit is preferably greater than the width of the middle section 110c and less than the width of the radiation ends 110a, 110b, so that when the radiation layer 11 is inserted into the clamping groove, the portions of the carrier 20' located on both sides of the single clamping groove and bounded by the bifurcated slit and the side can be pressed against one side surface of the radiation layer 11, and the portion of the carrier 20' located between the two bifurcated slits is pressed against the other side surface of the radiation layer 11. In other words, in this embodiment, the first joint portion J1' is the surface of the portion where the radiation layer 11 presses against the carrier 20' between the bifurcated slit and the side, and the surface of the portion where the radiation layer 11 presses against the carrier 20' between the two bifurcated slits; and the second joint portion J2' is two clamping grooves extending inward from two different sides of the carrier 20', and two bifurcated slits formed at the ends of the two clamping grooves.
[0018] Please refer to Figure 7 , 8 and 9, Figure 7 , 8 9 are exemplary diagrams of wireless radio frequency identification devices according to other embodiments of the present invention. Figure 7 , 8 The composition of the wireless radio frequency identification device shown in 9 is similar to Figure 2-4 and Figure 5-6 The difference between the wireless radio frequency identification device and the Figure 7 , 8 The first component 1' of the wireless radio frequency identification device of 9 further has a substrate 12. The substrate 12 can be a single-layer or multi-layer substrate, and the substrate 12 can be a flexible substrate (such as a polyimide (PI) substrate), a plastic substrate (such as an FR4 substrate), a copper foil substrate, an aluminum substrate or other metal substrates, but the present invention is not limited thereto.
[0019] Specifically, the radiation layer 11 is disposed on the substrate 12, so the first joint portion J1" is preferably located in the clamping groove of the substrate 12; the second joint portion J2" is preferably a protrusion extending from both sides of the carrier 20". Figure 7 In the embodiment, in a reference direction perpendicular to the side where any protrusion is arranged, the first combining portion J1" and the second combining portion J2" may be arranged in a staggered manner; Figure 8In the embodiment, in a reference direction perpendicular to the side where any protrusion is arranged, the first joint portion J1" and the second joint portion J2" can be arranged in alignment. In this way, the second joint portion J2" can pass through the first joint portion J1" (clamping channel), so when the first component 1' and the second component 2' are combined, the second joint portion J2" and the radiation layer 11 will be located on different sides of the substrate 12, and the second joint portion J2" will be against the substrate 12. Therefore, Figure 7 and 8 In the embodiment, the first joint portion J1" and the second joint portion J2" can be engaged with each other through the structure, and the first component 1' and the second component 2' can be separated by pulling the second joint portion J2" out of the first joint portion J1".
[0020] Please refer to Fig. 9 ,exist Fig. 9 In the embodiment, the first joint portion J1″ is a clamping piece for setting the substrate 12, and the second joint portion J2″ is a clamping groove of the carrier 20. Therefore, when the first joint portion J1″ is combined with the second joint portion J2″, the first joint portion J1″ (clamping piece) will pass through the second joint portion J2″ (clamping groove), so that the first joint portion J1″ can be against the carrier 20.
[0021] Although Figure 7 and 8 The first joint portion J1" is shown as a clamping groove spaced apart from the radiation layer 11. However, the clamping groove forming the first joint portion J1" can also be arranged to align with a portion of the outer periphery of the radiation layer 11, so that after the second component 2' is combined with the first component 1', the relative position relationship between the second component 2' and the radiation layer 11 can still be as shown in FIG. Figure 4 , 5 And 6 forms.
[0022] Please refer to Figure 1-4 , 5-6 and 7-8, in the wireless radio frequency device according to one or more embodiments of the present invention, the loop antenna 21 is preferably facing the radiation layer 11 (that is, the loop antenna 21 will be located between the carrier 20 / 20' / 20" and the radiation layer 11), but the loop antenna 21 can also be facing away from the radiation layer 11 (that is, the carrier 20 / 20' / 20" will be located between the loop antenna 21 and the radiation layer 11), but the present invention is not limited to this.
[0023] Please refer to Fig.10 ,in Fig.10 is a flow chart of a method for manufacturing a wireless radio frequency device according to an embodiment of the present invention.
[0024] Please refer to step S01 and Figure 2: A radiation layer 11 and a first joint portion J1 are formed on the first component 1, so that the radiation layer 11 forms a radiation pattern 110. In detail, the radiation layer 11 formed on the first component 1 in step S01 may be formed by etching, laser engraving or stamping aluminum or other suitable metal substrates to form the radiation layer 11, and a receiving platform is preferably provided below the aluminum or other suitable metal substrates to receive the radiation layer 11.
[0025] Please refer to Fig.10 And refer to Figure 7 In addition to using the radiation layer 11 and the first joint portion J1 as the first component 1 (step S01 and Figure 2 ), according to the manufacturing method of the wireless radio frequency device of this embodiment, the formation of the first component 1' can also be performed in step S01'. In detail, according to step S01', the formation of the first component 1' can also be to set the radiation layer 11 and the first joint portion J1" on the setting substrate 12, and use the radiation layer 11, the setting substrate 12 and the first joint portion J1" as the first component 1'. Among them, forming the radiation layer 11 in the first component 1' can be to form one or more radiation layers 11 in a single process; in addition, the method of forming the radiation layer 11 includes printing, sputtering or evaporating the radiation layer 11 on the setting substrate 12, and the present invention is not limited to this.
[0026] In addition, there is no restriction on the order of forming the radiation layer 11 and the first joint portion J1 ″ in step S01 ′. In other words, step S01 ′ may be performed by first forming the radiation layer 11 and then forming the first joint portion J1 ″, or by first forming the first joint portion J1 ″ and then forming the radiation layer 11 .
[0027] Please continue to refer to steps S01 and S01', wherein the first combination portion formed on the first component can be formed by using a portion of the radiation pattern as the first combination portion (for example, Figure 1-4 and Figure 5-6 The first joint J1 / J1' shown in FIG. 1 ); when the radiation layer is arranged as shown in FIG. Figure 7 and 8 When the substrate is set as shown, the first bonding portion formed on the first member can be achieved by die-cutting the substrate (for example, Figure 7-8 The first joint J1” shown).
[0028] Please refer to step S03 and Figure 2 or Figure 7, step S03 is to form a loop antenna 21, a chip 22 and a second joint J2 on the carrier 20 of the second component 2, wherein the chip 22 is electrically connected to the loop antenna 21. The formation of the loop antenna 21 on the carrier 20 described in step S03 can be performed in a manner similar to step S01', that is, the loop antenna 21 is printed, sputtered or evaporated on the carrier 20, or the aluminum or other suitable metal substrate on the carrier 20 is etched to form the loop antenna 21, and the formation of the loop antenna 21 on the carrier 20 can be to form one or more loop antennas 21 in a single process. After the loop antenna 21 is formed, the chip 22 is then set on the loop antenna 21, and the chip 22 is electrically connected to the loop antenna 21. The setting of the chip 22 on the loop antenna 21 is preferably performed by surface mounting technology (SMT), but the present invention is not limited thereto.
[0029] Please continue to refer to step S03, the second joint portion formed on the carrier board can be formed by die-cutting the carrier board to form a second joint portion in the form of a clamping groove (for example, Figure 1-4 The second joint portion J2 shown in the figure) or the carrier is die-cut so that the second joint portion is a protrusion extending from the carrier (for example, Figure 5-6 and Figure 7-8 In addition, there is no restriction on the order of forming the loop antenna, the chip and the second combining portion on the carrier of the second component in step S03. In other words, step S03 can be performed by first forming the loop antenna and the chip and then forming the second combining portion, or by first forming the second combining portion and then forming the loop antenna and the chip.
[0030] in, Fig.10 The illustrated steps S01 and S01 ′ are executed before the step S03 , but the steps S01 and S01 ′ may also be executed after the step S03 or simultaneously with the step S03 , and the present invention is not limited thereto.
[0031] Please continue to refer to Fig.10 And refer to Figure 2 After the first component 1 and the second component 2 are formed, step S05 is then performed to detachably combine the first combining portion J1 and the second combining portion J2, wherein the radiation layer 11 and the circular antenna 21 are electromagnetically coupled to each other, and the second component 2 itself has a first transmission distance, and the first component 1 and the second component 2 combined with each other have a second transmission distance, so that when the first combining portion J1 and the second combining portion J2 are combined, the second transmission distance of the combined first component 1 and the second component 2 is greater than the first transmission distance of the second component 2 itself, and when the first component 1 or the second component 2 is to be replaced, it can be achieved by separating the first combining portion J1 and the second combining portion J2.
[0032] In summary, according to one or more embodiments of the wireless radio frequency device and the manufacturing method thereof of the present invention, the radiation layer and the loop antenna can be combined with one or more joints in a detachable manner. Therefore, for example, when one of the radiation layer or the loop antenna of the wireless radio frequency device needs to be replaced, only one of them can be replaced to avoid the other one that does not need to be replaced being discarded together, causing unnecessary waste. According to one or more embodiments of the wireless radio frequency device and the manufacturing method thereof of the present invention, a detachable / replaceable wireless radio frequency device can be used so that the manufacturer does not need to re-produce a new wireless radio frequency device due to customer demand, thereby avoiding the problem of manufacturers' stockpiling.
