Description
Technical field
It is inner or invest its surperficial RFID electronic tag that the utility model relates to a kind of information carrier of can implanting, and belongs to information electronic and rubber manufacturing machinery manufacture field.
Background technology
At present the RFID electronic tag is applied to logistics transportation, allotment as data message carrier, feedback terminal or in the product lifecycle information system management of net environment, is no longer only a kind of technological concept.
The RFID electronic tag has unique identification code, after it is implanted information carrier (as rubber tyre) inside or invests its (as cargo container) surface, is combined into an integral body with it on the basis that does not affect the carrier quality.Under the driving of extraneous read-write equipment, send at any time/read and write data, monitoring carrier that can be real-time is being produced, sold and used, is being settled a claim or the omnidistance management of information-based monitoring.
The RFID electronic tag is mainly to be connected the sending/receiving that realizes data with radio-frequency module by antenna, can form to a certain degree deflection and deformation in manufacturing or use procedure due to information carrier, special when being applied to rubber tyre, can directly cause antenna and electronic installation because of break, damage or aging the separation, therefore improve the robustness that firm degree that antenna is connected with electronic tag can effectively improve electronic tag.
As disclose following scheme in first to file, application number is ZL200920252556.4, name is called the RFID electronic tire tag, this application has adopted the electronic tag of spring antenna structure, with after the compression of the welding end of spring antenna again together with radio-frequency module is welded and fixed, and other parts of spring antenna side direction far-end along equidirectional, spiral extension to substrate still.
The antenna structure of such scheme, when being subject to force-extension or the higher factors such as operating ambient temperature are done the used time, antenna may be shaken off the constraint of scolding tin and separate with radio-frequency module.Trace it to its cause is to form direct stressed transmission between compressed welding end and the turn that extends to the side direction far-end, do not form any slowing down or attenuation effect, be difficult to effectively external force resistance or the high-temperature factor destruction for syndeton between scolding tin and welding end.
In view of this, the special present patent application that proposes.
The utility model content
RFID electronic tag described in the utility model, its purpose is to address the above problem and will be assemblied in antenna on substrate and be designed to 2 parts of extending along 2 directions, the external force of coming from substrate-side to the far-end transmission or the welded power of other destructions are weakened and decay at the welding end of antenna, thereby improve welded stress stability and interference free performance between antenna welding end and substrate, and then improve the robustness of RFID electronic tag in whole life cycle.
For realizing above-mentioned purpose of design, described RFID electronic tag mainly includes:
Substrate,
Be arranged at the electronic chip on substrate,
And, be assemblied in one group of antenna of electronic chip both sides.
The difference with the prior art part is, described antenna has the first of extending along first direction, first have several in the shape of a spiral, continuously arranged turn;
With first continuous, along the second portion of second direction spiral extension, second portion has at least one complete turn;
Realize antenna in the assembling of electronic chip sidepiece by second portion being welded in substrate, first is in elasticity, indefinite state on multiple directions with respect to second portion.
As above-mentioned basic scheme, first that antenna has, second portion extend along first direction, second direction respectively respectively, namely consist of the turn elastic reset of 2 parts and are subjected to External Force Acting and stretch or the direction compressed is not identical.
The place will be after antenna be fixed on substrate by welding technology at second portion, and first is in free state on multiple directions with respect to second portion, can be flexibly crooked, flexible and torsion.Therefore, when external force is passed to second portion by first, only be equivalent to the turn from lateral action in second portion, because the central axis (identical with the elastic reset direction) of second portion turn is not identical with the extension direction of first, external force or other destructive power are weakened and are decayed at the antenna welding end, thereby the soldering reliability of antenna and substrate is strengthened greatly.
For improving further second portion in the stability of when welding syndeton that forms, can be on substrate, welding second portion place is provided with through hole, the soldering paste that welds second portion runs through through hole and forms the first rivet arrangement.
After welding, the soldering paste after curing is connected in both side surface with substrate fully with second portion, thereby antenna and substrate form stable syndeton on the whole.
The additional innovative approach of more optimizing is that during welding, soldering paste is poured into the inner ring of second portion and forms the second rivet arrangement.Namely at substrate one side surface, soldering paste (usually can adopt soldering tin technique and form tin cream) pours into and is full of, clogs second portion, thus strengthen second portion with the welding of substrate tight and soundness.
The connective stability of soldering paste and second portion turn when pouring into for improving, the improvement project that can take is that the maximum pitch between the second portion turn is less than the minimum pitch between first's turn.
Namely before welding, the turn of second portion is compressed and reduce its mutual pitch.Dwindling of pitch can be improved the compactedness that is connected more fully between soldering paste and turn.
And during because of External Force Acting, between first and second portion, pitch is different, also can cause the difference of spring vibration frequency and amplitude, thereby more aggravate external force in the decay of antenna welding end.
In addition, the pitch between described first turn is equal, and the pitch between the second portion turn equates, namely takes equidistant turn arrangement architecture.The design of phase constant pitch is for the sharpness that improves antenna send and receive data-signal and simplified processing process complexity.
Be comparatively preferred embodiment, the first direction that described first extends, perpendicular with the second direction that second portion extends.
In sum, the utility model RFID electronic tag has the following advantages:
1, antenna has 2 parts of extending along different directions, and the antenna welding end that therefore is connected with substrate has higher stress stability and interference free performance, and the robustness of whole RFID electronic tag is improved significantly.
2, the comparatively stable data communication performance of RFID electronic tag tool of application enhancements aft antenna.
3, the RFID electronic tag can bear higher processing, the stress in use procedure and deflect deformation.
