DETAILED DESCRIPTION

[0021] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] The utility model is designed to design a stacking tag that integrates radio frequency and detection. In practical applications, such as Figures 1 to 4 As shown, the specific design includes a carrier substrate 1, an RF chip 2, a main trace 3, a first detection trace 4, a second detection trace 5, and a third detection trace 6; wherein the RF chip 2 and the main trace 3 are arranged on the same surface of the carrier substrate 1, one end of the main trace 3 is connected to the high-frequency RF transmitting end of the RF chip 2, and the other end of the main trace 3 is connected to the high-frequency RF receiving end of the RF chip 2, and the main trace 3 arranged in a closed loop constitutes a high-frequency radiation antenna connected to the RF chip 2.

[0023] The first detection trace 4 and the third detection trace 6 are arranged on the surface of the carrier substrate 1 where the RF chip 2 is arranged, and the second detection trace 5 is arranged on the other surface of the carrier substrate 1 facing away from the surface where the RF chip 2 is arranged. One end of the first detection trace 4 is connected to one detection end of the RF chip 2, and the other end of the first detection trace 4 is connected to the same side end of the first conductive detection component 7 that runs through both sides of the carrier substrate 1. The two ends of the second detection trace 5 are respectively connected to the same side end of the first conductive detection component 7 and the same side end of the second conductive detection component 8 that runs through both sides of the carrier substrate 1. One end of the third detection trace 6 is connected to the same side end of the second conductive detection component 8, and the other end of the third detection trace 6 is connected to the other detection end of the RF chip 2. The first detection trace 4 and the third detection trace 6 are not in contact with the main trace 3.

[0024] Along the projection direction perpendicular to the surface of the carrier substrate 1 , the projection of the second detection trace 5 is located within the overall projection of the RF chip 2 , the main trace 3 , the first detection trace 4 , and the third detection trace 6 .

[0025] The above-mentioned stacked tag that integrates radio frequency and detection is designed. In order to improve the efficiency of routing under the radio frequency tag, regarding the possible spatial intersection in the routing structure, two embodiment structures are designed in actual application, such as Figures 1 to 4As shown, the structure of embodiment 1 is further designed to add a high-frequency bridge 9 and a secondary routing line 10. The high-frequency bridge 9 is arranged on the surface of the carrier substrate 1 where the second detection routing line 5 is arranged, and the two ends of the high-frequency bridge 9 are respectively connected to the same side end of the first high-frequency component 11 and the same side end of the second high-frequency component 12 that penetrate through the two sides of the carrier substrate 1; one end of the main routing line 3 is connected to the high-frequency RF transmitting end of the RF chip 2, and the other end of the main routing line 3 is connected to the same side end of the first high-frequency component 11. The secondary routing line 10 is arranged on the surface of the carrier substrate 1 where the main routing line 3 is arranged, and one end of the secondary routing line 10 is connected to the same side end of the second high-frequency component 12. The secondary routing line 10 The other end is connected to the high-frequency RF receiving end of the RF chip 2, and the high-frequency radiation antenna connected to the RF chip 2 is composed of a main routing line 3, a high-frequency bridge 9, and a secondary routing line 10 arranged in a closed loop in series, and along the projection direction perpendicular to the surface of the carrier substrate 1, there is a projection section of the main routing line 3 or a projection section of the secondary routing line 10 that intersects with the projection of the high-frequency bridge 9, and the first detection routing line 4 and the third detection routing line 6 are not in contact with the secondary routing line 10; along the projection direction perpendicular to the surface of the carrier substrate 1, the projection of the high-frequency bridge 9 is located within the overall projection of the RF chip 2, the main routing line 3, the secondary routing 10, the first detection routing line 4, and the third detection routing line 6.

[0026] In order to cooperate with the design of penetrating the carrier substrate 1 under the above-mentioned radio frequency tag structure, in actual application, a protective film 13 is further designed to be added. The protective film 13 is covered on the high-frequency bridge 9. The design of the protective film 13 is that all structures on the surface of the carrier substrate 1 are fragile. In order to protect the high-frequency bridge 9 on the surface of the carrier substrate 1, a non-fragile protective film 13 is covered on the high-frequency bridge 9. When the surface of the high-frequency bridge 9 on the carrier substrate 1 is attached to an object and then torn off, the second detection trace 5 on the surface of the high-frequency bridge 9 on the carrier substrate 1 will be damaged, and the high-frequency bridge 9 will be damaged due to the protective film. The existence of 13 is not affected, that is, the function of detecting the breakage of the detection line is realized, and the original performance of the high-frequency label is retained; and in practical applications, the adhesive force between the protective film 13 and the supporting substrate 1 is designed to be greater than the adhesive force between the protective film 13 and the attached object, so as to ensure that when the label designed by the utility model is torn off from the attached object, the high-frequency bridge 9 can be protected; and the adhesive force between the second detection wiring 5 and the supporting substrate 1 must be designed to be less than the adhesive force between the second detection wiring 5 and the attached object, so as to ensure that when the label is torn off, partial or complete peeling-type breakage will occur between the attached objects.

[0027] In addition, as for the first conductive detection component 7 , the second conductive detection component 8 , the first high-frequency component 11 , and the second high-frequency component 12 penetrating through the two surfaces of the carrier substrate 1 , each wiring is connected thereto respectively, and riveting can be used for connection.

[0028] Regarding the spatial intersection that may occur in the routing structure, the structural design of Example 2 also includes a straight-line insulating member, wherein both ends of the insulating member are arranged on the surface where the RF chip 2 is arranged on the carrier substrate 1, and the main routing line 3 passes below between the two ends of the insulating member and is arranged on the surface where the RF chip 2 is arranged on the carrier substrate 1, and the main routing line 3 is arranged from one end to the other end of the upper surface of the insulating member. At the position where the insulating member is arranged, the main routing line 3 is arranged to achieve a spatial intersection.

[0029] The stacked label integrating radio frequency and detection designed by the utility model is applied in practice, and the radio frequency chip 2, the first detection trace 4, and the third detection trace 6 are designed to be located within the minimum enclosing area corresponding to the high-frequency radiation antenna, and the shape and size of the minimum enclosing area corresponding to the high-frequency radiation antenna are further designed to be compatible with the shape and size of the surface of the carrier substrate 1. That is, the utility model design makes the radio frequency tag structure and the detection trace structure in the same space through reasonable layout, thereby minimizing the overall volume of the designed label and reducing the cost.

[0030] In actual applications, the carrier substrate 1 and the protective film 13 are designed to use insulators. The carrier substrate 1 is made of materials such as PET, paper, etc. The material of the protective film 13 is non-fragile and can be PET, PP, PI, etc. All small structures contained in the two-sided structures of the carrier substrate 1 are conductors, which can be metals such as copper and aluminum, or conductive inks.

[0031] The stacked label integrating radio frequency and detection designed by the above technical scheme is equipped with a radio frequency tag structure and a detection wiring structure on both sides of the supporting substrate 1, and constructs an overlapping relationship with each other in the direction perpendicular to the surface of the supporting substrate 1, which effectively reduces the volume of the overall design and reduces the manufacturing cost. Furthermore, through the bridge structure, the radio frequency tag structure and the detection wiring structure are designed to span the two sides of the supporting substrate 1 respectively, thereby improving the efficiency of wiring layout. In actual applications, the overall designed stacked label can efficiently realize the detection function of the detection line break while retaining the high-frequency tag performance, thereby effectively improving the actual work efficiency.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
