Description
Technical field
The invention belongs to electronic tag manufacturing technology field, it is related to a kind of labeling method of label, it is more particularly to a kind of
For the labeling method of radio frequency label defective products.
Background technology
RFID tag with its data storage capacity it is big, read that distance is remote, on label data can encrypt, storage information change from
Such as a variety of advantages, are widely used in such as logistics, Drug Administration, government utility service, animal husbandry many-side.And its is reliable
Antifalsification and the rapidity of reading be also deciding factor that it progressively replaces bar code.In actual production, work as discovery
, it is necessary to be pin-pointed to substandard products during substandard products (weak mark), and it is marked, but current RFID technologies are in the multirow of small spacing
Realize that it is very difficult to be accurately positioned in the label production of multiple row.
Existing RFID Dry inlay defective product label defective products labeling methods have three major types：One is on defective products with
Non-conductive ink stamps black or red circular (or square) mark, the second is the paper label of black or red is sticked, the third is
Directly directly chip is punched with punch mechanism.The first has the disadvantage that the weak mark product in part are printed in Dry inlay semi-finished product
Fail mark, but lower processing procedure is judged to non-defective unit, has flaw as outward appearance and is electrically weak target product turnout to client, damages matter
Measure credit；There is for second operating speed slow in addition to having the shortcomings that the first, separately, do not coordinate main flow high speed board；The third
Shortcoming without the first, but operating speed is slower than second, and productivity is poor.
The content of the invention
For above-mentioned electronic tag, defective products marks slow operating speed, low production efficiency and stream to the present invention in process of production
Go out the deficiencies such as substandard products (weak mark), propose a kind of labeling method for radio frequency label defective products, can make easily to be mistaken for non-defective unit
Weak mark product become clear and definite defective products, the output of weak mark product can be effectively prevented, while maintaining target and sensor easily to differentiate
Function, the quality of electronic tag can be lifted and higher operating speed and production efficiency is maintained.
The technical scheme is that：A kind of labeling method for radio frequency label defective products, it is characterised in that bag
Include following operating procedure：
(1) Preliminary detection is carried out to radio frequency label；
(2) by the detection of step (1), weak mark product or defective work are filtered out；
(3) electrically conductive ink spray printing is carried out at weak mark product in step (2) or the core heart position of defective work, aed is formed
Short circuit paths；
(4) resistance is made on the antenna of two contacts of chip or chip correspondence position between two contacts using conductive material significantly
Reduction, makes the weak mark radio frequency label turn into defective products；
(5) in next step preparation process, known by electrical testing differentiation, visual personnel, sensor identification or machine vision
Not can determine whether radio frequency label is defective products；
(6) non-defective unit is exported, weak mark faulty materials scrap processing.
Radio frequency label described in step (1) is the radio frequency label with chip and antenna abcd paths, day
The abcd paths of line are paths, and a ends and d ends of antenna are to form open circuit with chip, and two electrodes of chip are led through anisotropy
Electric gemel connection is at a ends and d ends.
Preliminary detection described in step (1) is electrical testing.
Described in step (3) weak mark product or defective work are carried out with the spray printing of electrically conductive ink, spray printing position is in outside chip
Enclose, and two electrodes of the chip core heart or a ends and d ends of antenna is directed through electrically conductive ink and short-circuit.
Described in step (3) weak mark product or defective work are carried out with the spray printing of electrically conductive ink, makes the face of electrically conductive ink formation
Color and pattern easily differentiate it for defective products by human eye, or sensor inspection.
The resistance in described abcd paths refers to the former matching impedance of radio frequency label antenna, through step (4) to defective products
And after weak mark product is with the spray printed mark of electrically conductive ink, radio frequency label antenna match impedance becomes abcd paths parallel connection aed
Path, its impedance can be greatly reduced, and radio frequency label can be caused to fail, and former weak mark product become clear and definite defective products, through electrical
Instrument can clearly differentiate it for defective products when detecting, will not be judged to non-defective unit.
Beneficial effects of the present invention are：A kind of labeling method for radio frequency label defective products proposed by the present invention,
Operating procedure is simple, and operation principle is clear, replaces general black or red non-conductive ink using electrically conductive ink, and print position changes
Two electrodes of the former core heart are made to be directed through electrically conductive ink and short-circuit in chip periphery, primary circuit a to d points can only be walked outside chip
Abcd paths, after electrically conductive ink spray printing, form aed short circuit paths.Because of the short circuit of the end line network of chip two, less radio-frequency mark
The former matching impedance of label is greatly reduced, and this radio frequency label failure, former weak mark product become clear and definite defective products, in lower processing procedure with regard to only
Defective products can be judged to, non-defective unit will not be judged to, can effectively it is anti-blocking it is weak mark faulty materials reserve to client, improve defective products wireless
The precision of RF tag positioning, effectively prevent the output of weak mark product, while maintaining the function that target and sensor easily differentiate, energy
Lift the quality and the higher operating speed of maintenance and production efficiency of radio frequency label.
