Abstract

The utility model discloses an RFID sealed tag which includes a flexible substrate and an RFID responder. The flexible substrate is provided with a hole passing line. The flexible substrate is divided into an upper part and a lower part via the hole passing line. The RFID responder includes an integrated circuit chip and an antenna which is connected with the integrated circuit chip. The antenna is arranged on the upper part of the flexible substrate. The integrated circuit chip is arranged on the lower part of the flexible substrate. When the RFID sealed tag damages along the hole passing line, the connection between the integrated circuit chip and the antenna is affected, and at the same time, the RFID responder can not be operated, and the RFID responder can not communicate with an RFID inquiry device. The possible damage of the RFID sealed tag along the hole passing line can be detected through querying the responder. If the responder responds to the inquiry, the RFID sealed tag can be determined to be not damaged.

Description

The RFID seal laber

Technical field

The utility model relates to the electronics of packaged articles to be followed the tracks of and recognition technology field, particularly a kind of RFID seal laber.

Background technology

Having developed various technology follows the tracks of and identify objects.For example, usually bar code is applied on the article now, and this bar code can be scanned by optical mode, thereby identify the feature of the coding of these article or these article, for example the price of article.Yet, be between scanister and bar code, to need boresight based on the shortcoming of optical scanning technology.Thereby, if the bar code that applies not towards scanister, if perhaps object is included in chest, cargo transport crate or other the optional light tight packing, then can not recognition object.

With other reason, the RFID technology has developed into and need not to set up boresight and recognition object between scanister and identification label for this reason.Usually the RFID transponder (being transmitter/responsor) that is called the RFID label for short is thin rf receiver and transmitter, and it comprises integrated circuit (IC) chip and the antenna that is installed on the supporting substrate.Label can be that active or passive, active type comprises for the battery to the transceiver power supply, and the device of passive type carries out powered operation by the RF signal that is used for the inquiry label.

The integrated circuit (IC) chip of RFID label comprises RF circuit, steering logic circuit and storer, and antenna comprises the metallic conductor such as copper or aluminium in the inductive coil that forms on the supporting substrate substantially.Capacitor can additionally be formed by metallic conductor, thereby the resonance of antenna is adjusted to the operating frequency of expectation.Base material is normally such as the thin soft film of the plastics of polyester or polyimide.For example, polyester base material commonly used is polyethylene terephthalate (PET).Formed RFID label can be thin in the extreme by this way, for the thickness of integrated circuit (IC) chip, is below 0.5 millimeter for example, and for the part on other zone of label, is below 0.1 millimeter.

Inquiry unit is used to read the object identification information in the storer of the integrated circuit (IC) chip that is stored in the RFID transponder.The RF signal of this inquiry unit launching code, even when label is not in the boresight of inquiry unit, the transponder that the RF signal of described coding also can be in the emitter range receives.Usually, transponder is reflected back inquiry unit with incident RF carrier wave, will be stored in simultaneously information coding in the storer in this process to described carrier wave.In the situation of rewritable label, can also be according to the information in the fresh information adjustment storer that is coded on the incident RF carrier wave.In this mode, the RFID transponder operated becomes the object identification data are received, store and launch by the storer in the chip back and forth.

Because transponder is thin, so they are easily integrally formed with additional supporting material, described supporting material for example is paper or such as the plastics of Polyvinylchloride (PVC).Therefore, RFID can be configured to the form of adhesive label or band, and they can easily be applied on the article, for use in the purpose of following the tracks of and identifying.

Compare with other form of recognition object, the significant advantage of RFID label is, they can be configured to roughly the application from motion tracking and identification, this is because they do not rely on the boresight of operation, for example, inquiry unit can be installed in the fixed position place on production line or the pack-thread, thereby at the article that carrying the RFID label during by inquiry unit, they are identified and follow the tracks of their position.As long as the article radio-frequency region that enters inquiry unit, then they just can be identified and not be subjected to following factor affecting, namely they towards, the position of RFID label on article, perhaps whether article are included in the packing container of sealing.For example will be through the article of inquiry location point in the time of expectation and when unrecognized, perhaps at article when it does not expect that the inquiry location point of settling is identified, this tracker is so that early detection missing or wrong direction to article.

Although traditional RFID label provides useful device for tracking and the identification of object, still be that label rather than its appended object are asked device identification.Thereby, can be by article be taken out from the RFID tracker, thus and simultaneously label is stayed original position the RFID tracker was lost efficacy.For example, in some cases, by with label from article take off and again with label placement container, and will from the container of this article, take out with the article of label in the mode that is not detected.In other situation, the RFID label only is applied on the packing of article, and thereby simply by from the packing with label, taking out article, and packing is stayed in the system, and is taken out article in the mode that can't detect.At inquiry location point subsequently, label will be replied inquiry unit, and system can't detect article and be removed.

Follow the tracks of with the inefficacy of recognition system be logistics with relevant carrier in an important problem, especially those relate to high value relative to the transportation of portable article or move, for example, wrist-watch, wine, jewelry and mobile phone.Such article have relatively high loss by theft rate, and stolen can relating in sealing or again before the airtight container, take out one or more article from the container such as the paperboard case.Therefore, until container before open the final destination, can not found to have things stolen, at that time, determine that with being difficult to which the stage article in supply and conveyer chain are removed.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of RFID seal laber for the existing deficiency of prior art.

Technical problem to be solved in the utility model can be achieved through the following technical solutions:

The RFID seal laber, comprise flexible substrate and RFID transponder, be provided with a perforation line at described flexible substrate, this flexible substrate is separated into upper and lower two parts by described perforation line, described RFID transponder comprises integrated circuit (IC) chip and is connected to antenna on the described integrated circuit (IC) chip, wherein antenna is positioned on the described flexible substrate on the part, and described integrated circuit (IC) chip is positioned under the described flexible substrate on the part.

The utility model is when the RFID seal laber is damaged along perforation line, and being connected and will being affected between integrated circuit (IC) chip and the antenna causes simultaneously the RFID transponder to operate, and can not communicate by letter with the RFID inquiry unit.Therefore, can detect the RFID seal laber along the breakage that may occur of perforation line by interrogator-responder.If then the transponder response inquiry can assert that then the RFID seal laber does not have breakage.
