Abstract

The utility model discloses a cigarette packaging box with an electronic tag capable of increasing the read/write sensitivity. The cigarette packaging box comprises a box body and the electronic tag which is arranged on the box body, wherein the electronic tag comprises a chip, a coupling ring, an oscillator arm and an oscillator, the oscillator arm and the chip are connected to two connecting ends of the coupling ring, the tail end of the oscillator arm is connected with the oscillator, and the oscillator arm and the chip are positioned at two opposite sides of the coupling ring; the length of the oscillator arm is reduced while the area of the oscillator is increased, and the increased area of the oscillator is the area formed by the reduced length of the oscillator arm. Compared with the prior art, according to the cigarette packaging box disclosed by the utility model, the oscillator arm and the chip are arranged in opposite positions of the coupling ring, one of the oscillator arm and the chip is arranged above the coupling ring, the other one of the oscillator arm and the chip is arranged under the coupling ring, the oscillator arm and the chip are not arranged at the same side, thus the coupling between the oscillator arm and the coupling ring is enhanced, and the bandwidth can be increased; by reducing the length of the oscillator and increasing the area of the oscillator, the resonance frequency of the electronic tag can be effectively increased, and the sensitivity of the electronic tag can be increased.

Description

There is the electronic tag cigarette packing case that improves read-write sensitivity

Technical field

The utility model relates to a kind of packing chest, specifically a kind of electronic tag packing chest for cigarette package, turnover and identification.

Background technology

The Electrical Parts smoke box using at China's tobacco business in recent years, the built-in information such as electronic tag Ba Gaixiang content process unit, the name of an article, specification, code, quantity and date manufactured, adopt wireless radio-frequency to write the chip in label.Along with this part cigarette displacement node, by wireless recognizing apparatus, in each flow processs such as warehouse-in, storage, outbound, entrucking transportation and arrival confirmation, reached the effect that known, visual, controlled sensates is networked, be subject to the favor of the sector.

Generally, common electronic tag has early the higher characteristic of sensitivity in 840 MHZ～960MHZ uhf-range, but generally when antenna is high when entering metal, the resonant frequency of electronic tag can change.The sensitivity of label also can worsen simultaneously, and this is main because label antenna and metal self check meeting produce eddy current, between while label antenna and metal, also can produce parasitic capacitance, and these 2 can have influence on tag sensitivity variation, and label resonant frequency is too low simultaneously.

Summary of the invention

Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, thereby and provide a kind of change oscillator arms and chip position to increase bandwidth, improve the electronic tag cigarette packing case of read-write sensitivity.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of electronic tag cigarette packing case with raising read-write sensitivity, comprise casing and be placed in the electronic tag on casing, described electronic tag comprises chip, coupling ring, oscillator arms and a period of time, described oscillator arms and chip are connected to two coupling ends of described coupling ring, end in oscillator arms connects described a period of time, it is characterized in that: described oscillator arms and chip are positioned at the relative both sides of described coupling ring.

The area in described a period of time increases, and the length of oscillator arms reduces, and a period of time area increased is the area that length that oscillator arms length reduces forms.

Described oscillator arms length has reduced by 1/5～1/2 ratio.

In described oscillator arms, be also provided with a metal level.

Compared with prior art, the beneficial effects of the utility model are:

1, the utility model oscillator arms is arranged on the position that coupling ring is relative with chip, one above coupling ring, one below coupling ring, not with on one side, the benefit of bringing is like this that the coupling between oscillator arms and coupling ring strengthens, and can play the effect that increases bandwidth.

2, the utility model reduces oscillator arms length, and a period of time area increases, and the main purpose in antenna a period of time is exactly to be chip transmitting energy, a period of time area increases, antenna is accepted the also corresponding increase of area of electromagnetic radiation, thus the gain that has improved label, so effectively improved the sensitivity of label.Also just because of reducing of the length of oscillator arms also effectively promoted the resonant frequency of label.Meanwhile, because antenna oscillator arm lengths reduces, so brought inductance value also can reduce.Can play like this effect that antenna better mates with label chip.In addition, owing to having increased the metallicses such as aluminium skin in oscillator arms, be in fact to have widened antenna, can promote so first antenna broadband, it two can, by the resistance of its antenna own, further promote tag sensitivity.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is elaborated:

As Fig. 1, shown in Fig. 2, a kind of electronic tag cigarette packing case of the utility model, comprise casing 1 and be placed in the electronic tag 2 on casing, wherein electronic tag 2 comprises chip 21, coupling ring 23, oscillator arms 24 and a period of time 22, the place that oscillator arms 24 is connected with coupling ring 23 is relative with the position of chip 21, not on one side same, end in oscillator arms 24 connects a period of time 22, the area in a period of time increases to S2 by original S1, the length of oscillator arms reduces to L2 by original L1, the length that oscillator arms reduces and the product of oscillator arms width H are the area that oscillator arms reduces, this area is just in time the area increasing in the utility model electronic tag a period of time.A period of time area increased is generally the area that oscillator arms length 1/5～1/2 forms.

In order further to increase the bandwidth of oscillator arms, reduce the resistance of oscillator arms, the utility model is also also provided with a metal level in oscillator arms, such as aluminium skin etc.
