Description

A kind of UHF RFID label for cigarette case

Technical field

The utility model relates to radio frequency identification electronic label technical field.

Background technology

In tobacco business, in order to set up the technological process of production and the efficient system for the distribution of commodities, the sorting system played a decisive role in logistics and dispensing is core.The technology of various ways is imported into cost saving, raises the efficiency, reduces intensive labor power.The sorting system of traditional tobacco business uses RS485 Bus interface image data, and it has the advantage that bar code communicates with remote high-speed induction with optical scanner, multinode support.But the shortcomings such as bar code system is subject to contamination by dust, network speed is slow, inconvenience processes in real time, slave node difficult communication that it also exists simultaneously.Improve with use many main websites structure, communication speed, error detection function, the High-speed Control general ability area network bus technology such as miscue transmission compare with bar code, advantage more type hand rfid system has the trend replacing this sorting system gradually.

In tobacco manufacturing industry, infotech is utilized to control the activity in production situation of tobacco product in real time, for the production cost that improves the quality of products, reduces, shorten various demands that the delivery cycle meets client in time, the flexible system of constructing quick response environment drastic change is very important, although the developing by leaps and bounds of RFID technique makes being built into of the production information system of tobacco business necessity may, but when importing to cigarette case package identification, require the limitation of the technology that the expense fundamentally solving the importing of RFID label tag initial stage is born and in cigarette case, conduction packaging material is brought.

In cigarette industrial field, compared with wholesale/retail price, the ratio of various tax is 70% ~ 80%, accounts for very large proportion.Therefore, in manufacturing cost, during every box cigarette RFID quote is used, the initial stage of label introduces expense and accounts for sizable proportion.

Analyze current tobacco business RFID and be suitable for case, case or cigarette case package, the circulation of pallet packing, logistic industry all the time can be found, adopt and stick on the form of special tags, namely in cigarette case package, heat-shrinking plastics (OPP film class) packaging omnidistance 13.56MHz antenna or the UHF bandwidth label sticked in forward and backward and side of cigarette case package.Traditional cigarette case package process, in order to prevent the change of the moisture content of product in circulation, absorb life gas, often needs the plastics package through OPP film class and aluminium case packing.From the viewpoint of electric, owing to being used as the RFID label tag of the raw-material aluminium case of cigarette case package close to attachment, form electric equipotential surface, the reflection efficiency that RFID label tag and parasitic elements can be caused to bring out bring is low, resonant frequency shift, the overall readable distance of rfid system and one discrimination significantly low.So adopt the method for outside adhesive label, its fundamental limitations is that the electrical specification of rfid system is low, simultaneously, in the tobacco retail price of cigarette case package, tax ratio is up to 70-80%, the cost that tobacco leaf production enterprise sensation imports RFID label tag is maximum burden, thus fundamentally hinders the popularization of cigarette case package identification.

Utility model content

Adopt label to realize the problems referred to above existed in cigarette case package identifying to overcome tradition, the utility model provides a kind of UHF RFID label for cigarette case.

The technical scheme that the utility model is adopted for achieving the above object is: a kind of UHF RFID label for cigarette case, comprise INLAY substrate 3 and ring label 4, ring label 4 is arranged in INLAY substrate 3, label chip 5 is positioned at center, ring label 4 minor face side, UHF RFID label covers on the gap 2 on the tinfoil of cigarette case 1 side, and label chip 5 is positioned at gap 2 place.

The described wide 0.2mm-2mm in gap 2, long 40mm-80mm.

Described ring label 4 is of a size of 24mm*10mm, and ring label live width is 0.5mm.

UHF RFID label for cigarette case of the present utility model, INLAY label is covered on the gap of cigarette case 1 side tinfoil, solves from electric aspect owing to being used as close to the RFID label tag of attachment, cigarette case package raw-material aluminium case forms that the reflection efficiency that electric equipotential surface causes RFID label tag and parasitic elements to be brought out bringing is low, the overall readable distance of resonant frequency shift, rfid system and the significantly low problem of one discrimination; Further, overall INLAY label covers on gap, avoids tinfoil packaging causes cigarette humidity resistance decline because cut gap.
