Description
Technical Field
[0001] This utility model relates to a non-closed surround detection tag, belonging to the field of radio frequency tag technology. Background Technology
[0002] RFID, as a passive IoT identification technology, has been applied in an increasing number of scenarios. In fields such as apparel, logistics, and asset management, RFID technology is adopted due to its unique advantages such as being passive, capable of group reading, and cost-effective. For an RFID system to function properly, the tag, reader, and communication link must all be in normal working order. Generally, RFID chips with detection functions have closed detection lines to achieve normal detection capabilities, and these closed detection lines are usually attached to the item with double-sided tape to prevent tampering. However, these closed detection lines can still be completely peeled off using non-destructive methods such as adhesive removers, thus posing a potential hazard. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a non-closed surround detection tag, and design a closed structure for the detection structure connected to the radio frequency chip to improve the application efficiency in detection scenarios.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention designs a non-closed surround detection tag, including a carrier substrate and an RF chip disposed on the surface of the carrier substrate, wherein the RF port of the RF chip is connected to an RF radiation structure disposed on the surface of the carrier substrate.
[0005] The two detection ports of the radio frequency chip are respectively connected to one end of the first trace and one end of the second trace on the surface of the substrate. The first trace and the second trace do not intersect each other. The first target area is a region on the surface of the substrate that is a preset distance away from one end of the first trace. The other end of the first trace and the other end of the second trace extend into the first target area on the surface of the substrate. The first trace and the second trace pass through at least one preset target position in the first target area in sequence. A preset distance is maintained between the local segments of the first trace and the local segments of the second trace at each target position.
[0006] The second target area is defined as a region on the surface of a pre-defined carrier substrate that is a pre-defined distance from its other end. Each conductive region is set in the second target area on the surface of the carrier substrate. The number of conductive regions is equal to the number of target positions in the first target area. The relative positional relationship between each conductive region is the same as the relative positional relationship between each target position. Each conductive region corresponds one-to-one with each target position. Each conductive region is larger than the minimum outer enclosure area of the first trace local segment and the second trace local segment in the corresponding target position.
[0007] Based on the carrier substrate being wound around the target object, the first trace segment and the second trace segment in each target position in the first target area on the carrier substrate are in contact with the corresponding conductive area in the second target area, thereby realizing the conductive connection between the first trace segment and the second trace segment in each target position through the corresponding conductive area, thus forming a detection structure for radio frequency chip connection.
[0008] As a preferred technical solution of this utility model: the distribution area of the radio frequency chip, the radio frequency radiation structure connected to the radio frequency chip, and the detection structure extends from the first target area to the second target area on the surface of the substrate.
[0009] As a preferred technical solution of this utility model: the first wiring and the second wiring are laid out with a preset distance between them.
[0010] As a preferred technical solution of this utility model: the first target area and the second target area are respectively disposed on two different surfaces of the supporting substrate.
[0011] As a preferred technical solution of this utility model: an extension region substrate is provided at the edge of the second target area on the carrier substrate, and an adhesive is provided on the surface of the extension region substrate on the same side as the second target area. Based on the fact that the first trace local segment and the second trace local segment in each target position of the first target area are in contact with the corresponding conductive area in the second target area, the extension region substrate is flipped so that the surface of its adhesive covers each conductive area in the second target area.
[0012] As a preferred technical solution of this utility model: a perforated line is arranged in the area between the second target area and the extended area substrate on the supporting substrate.
[0013] As a preferred technical solution of this utility model: the radio frequency radiation structure includes an inductor ring disposed on the surface of the substrate and two radiation bodies, the radio frequency chip is disposed on the inductor ring and the radio frequency port of the radio frequency chip is connected to the inductor ring, and the two radiation bodies are respectively connected to the inductor ring.
[0014] The non-closed surround detection tag of this utility model, compared with the prior art, has the following technical effects:
[0015] This invention designs a non-closed surround detection tag. Based on a carrier substrate with an RF chip forming an RF radiation structure, the RF chip's two detection ports are connected to a first and second trace. Various target positions are designed, maintaining a preset distance between local segments of the first and second traces. These are combined with matching conductive areas designed on the carrier substrate. The tag is then wrapped around a target object, with each target position contacting its corresponding conductive area to achieve a closed connection between the first and second traces. This design combines a closed detection structure with the application of wrapping around a target object, enabling the detection of tag damage without affecting the tag's normal RF function, thus improving work efficiency in practical applications.

Detailed Implementation
[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0019] This utility model designs a non-closed surround detection tag, which, in practical applications, such as... Figure 1 As shown, it includes a carrier substrate 1 and an RF chip 2 disposed on the surface of the carrier substrate 1. The RF port of the RF chip 2 is connected to an RF radiation structure 3 disposed on the surface of the carrier substrate 1.
[0020] The radio frequency radiation structure 3 includes an inductor ring 3-1 disposed on the surface of the substrate 1 and two radiation bodies 3-2. The radio frequency chip 2 is disposed on the inductor ring 3-1, and the radio frequency port of the radio frequency chip 2 is connected to the inductor ring 3-1. The two radiation bodies 3-2 are respectively connected to the inductor ring 3-1.
[0021] like Figure 1As shown, the two detection ports of the radio frequency chip 2 are respectively connected to one end of the first trace 4 and one end of the second trace 5 arranged on the surface of the carrier substrate 1, and the first trace 4 and the second trace 5 do not intersect each other. The first target area 6 is a region on the surface of the carrier substrate 1 that is a preset distance away from one end of the first trace 4. The other end of the first trace 4 and the other end of the second trace 5 extend into the first target area 6 on the surface of the carrier substrate 1. The first trace 4 and the second trace 5 pass through at least one preset target position 7 in the first target area 6 in sequence, and a preset distance is maintained between the local segments of the first trace 4 and the local segments of the second trace 5 in each target position 7.
[0022] like Figure 1 As shown, the second target area 8 is a region on the surface of the pre-set carrier substrate 1 that is a preset distance from its other end. Each conductive region 9 is provided in the second target area 8 on the surface of the carrier substrate 1. The number of conductive regions 9 is equal to the number of target positions 7 in the first target area 6. The relative positional relationship between each conductive region 9 is the same as the relative positional relationship between each target position 7. Each conductive region 9 corresponds one-to-one with each target position 7. Each conductive region 9 is larger than the minimum outer enclosure area of the local segment of the first trace 4 and the local segment of the second trace 5 in the corresponding target position 7.
[0023] like Figure 1 As shown, based on the carrier substrate 1 being wound around the target object, the partial segments of the first trace 4 and the partial segments of the second trace 5 in each target position 7 of the first target region 6 on the carrier substrate 1 are in contact with the corresponding conductive region 9 in the second target region 8, thereby realizing the conductive connection between the partial segments of the first trace 4 and the partial segments of the second trace 5 in each target position 7 through the corresponding conductive region 9, thus forming the detection structure connected to the radio frequency chip 2.
[0024] The non-closed surround detection tag structure designed above can be applied in practice, such as... Figure 1 As shown, the distribution area of the radio frequency chip 2, the radio frequency radiation structure 3 connected to the radio frequency chip 2, and the detection structure extends from the first target area 6 to the second target area 8 on the surface of the substrate 1. When each target position 7 is electrically connected to the corresponding conductive area 9, it can cover one circumference of the structure surrounding the substrate 1, thereby achieving all-round detection and improving detection efficiency.
[0025] Furthermore, in the actual product design, the first wiring 4 and the second wiring 5 can be designed to maintain a preset distance for their arrangement; and regarding the winding installation method of the bearing substrate 1 around the target object, the first target area 6 and the second target area 8 can be designed to be respectively located on two different surfaces of the bearing substrate 1.
[0026] During the installation process around the target object, in order to improve the stability and firmness of the one-to-one conductive connection between each target position 7 and the corresponding conductive area 9, such as... Figure 1 As shown, an extensional substrate 10 is designed and set at the edge of the second target area 8 on the carrier substrate 1. An adhesive is set on the surface of the extensional substrate 10 on the same side as the second target area 8. Based on the fact that the partial segments of the first trace 4 and the partial segments of the second trace 5 in each target position 7 of the first target area 6 are in contact with the corresponding conductive area 9 in the second target area 8, the extensional substrate 10 is flipped so that the surface set with adhesive covers each conductive area 9 in the second target area 8. In further practical applications, in conjunction with the adhesive design of the extensional substrate 10, a serrated line 11 is laid through the carrier substrate 1 in the area between the second target area 8 and the extensional substrate 10 on the carrier substrate 1, which further improves the detection efficiency in practical applications.
[0027] Applying the above-designed non-closed surround detection tag to practice, firstly, the tag is passed through or wrapped around the target object, and then each target position 7 is brought into contact with the corresponding conductive area 9. That is, a partial segment of the first trace 4 and a partial segment of the second trace 5 in each target position 7 are brought into contact with the corresponding conductive area 9 in the second target area 8. Then, a command is sent to the tag through a reader. When the detection function feedback is normal, the tag installation is completed. When the tag's detection structure is damaged, or each target position 7 is completely separated from the corresponding conductive area 9, the failure of the detection function can be detected when the tag is read by a handheld device, that is, the tag is found to be damaged.
[0028] The non-closed surround detection tag designed in the above technical solution is based on a carrier substrate 1 with an RF chip 2 to build an RF radiation structure 3. The two detection ports of the RF chip 2 are connected to the first trace 4 and the second trace 5. Each target position is designed to maintain a preset distance between a local segment of the first trace 4 and a local segment of the second trace 5. In conjunction with the corresponding conductive areas 9 designed on the carrier substrate 1, the tag is wrapped around the carrier substrate 1 and placed around the target object. The contact between each target position and the corresponding conductive area 9 achieves the connection and closure of the first trace 4 and the second trace 5. The design combines the closed detection structure with the application method of wrapping around the target object. It achieves the detection of whether the tag is damaged without affecting the normal RF function of the tag, thus improving the work efficiency in practical applications.
[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
