Description
Technical field
The present invention relates to bar code, Quick Response Code makes field, particularly relates to a kind of bar code based on magnetic particle, two dimension
Code and preparation method thereof.
Background technology
Bar code, Quick Response Code store as a kind of high content information, transmit and identification technology, just obtain from being born
The concerns of many countries in the world.The states such as the U.S., Germany, Japan, not only bar code, planar bar code technology are applied to public security,
Department's management to all kinds of certificates such as diplomatic, military, and it is applied to the department such as customs, the tax to all kinds of forms and ticket
According to management, the management that commodity and goods are transported by the department such as business, transportation, the postal service management to postal parcel,
The field of industrial production automated management to industrial production line.
Bar code, planar bar code technology research are started 1993 by China.Bar code, planar bar code technology are at me at present
The automobile industry automatic production line of state, medical first aid service card, foreign-related patent and case are charged, jewelry gem ornament manages,
Applied in expressway tol lcollection management and bank draft.
Bar code, Quick Response Code application in recent years initially enters the open field of circulation, in logistic label, has begun to use
The information such as the address that bar code represents place of departure, receive.The packing technique committee of International Organization for Standardization proposes packaging mark
The two-dimensional bar code standard signed, International Article Numbering Association proposes standardized two-dimensional bar code application rule in EAN UCC specification
Model, indicate the application of open logistics supply chain process two-dimensional bar code need to clearly, the application of 2D bar code technology just from
Past system single, local, that close is applied, and keeps in mind what formation opened, and globalization, standardization large-scale application system direction are sent out
Exhibition.
Along with the speed with Automatic Identification & Data Collections such as two-dimensional bar codes that improves constantly of social informatization degree is sent out
Exhibition, in recent years 2D bar code technology and other technologies mutually merge, interpenetrative trend more and more obvious.
Bar code, the manufacturing technology of Quick Response Code now are all printing technologies, locate after needing at high temperature to carry out ink
Reason, cannot printed upper Quick Response Code and bar code on the base material of non-refractory.So developing a kind of wide to the base material suitability
Method is a key problem in this field.
The method utilizing magnetic field pattern-making, has been widely used in scientific research.Magnetic field as one clean,
Efficient instrument can induce magnetic particle to form pattern in magnetic field under the effect of magnetic field modulator.Magnetic field modulator by
High-permeability material and low magnetic permeability material composition.As it is shown in figure 1, when magnetic field is vertically by high-permeability material,
The inside that magnetic field is tended to from material passes, and result in the magnetic flux density of high-permeability material near-surface region on vertical direction
Increase, and the magnetic flux density of high-permeability material near-surface region reduces in the horizontal direction.Same, when magnetic field is along perpendicular
Nogata is to during by low magnetic permeability material, and magnetic field is tended to walk around material and passed from the outside of material, result on vertical direction
The magnetic flux density of low magnetic permeability material near-surface region reduces, and low magnetic permeability material near-surface region in the horizontal direction
Magnetic flux density increase.
By the most alternately arranged to high-permeability material and low magnetic permeability material, put into the magnetic that just can make magnetic field in magnetic field
Flux density graded.Replaced by high-permeability material iron foil sheet (300 μ m-thick) and low magnetic permeability material aluminium foil (300 μ m-thick)
The magnetic field modulator rearranged is put in the uniform magnetic field that magnetic flux density is 20mT, and it is vertical on magnetic field modulator surface
The magnetic flux distribution of direction 100 μm plane is as shown in Figure 2.If bar code, the figure of Quick Response Code are designed in magnetic field modulator surface
Case, pattern uses the material of high magnetic permeability to be made.After magnetic field modulator is put in vertical direction magnetic field, will go out in magnetic field
The region that an existing bar code, the flux density gradients of pattern in 2 D code change, as shown in Figure 3.
Magnetic particle is mainly acted on by magnetic field force in magnetic fieldIt is all constant, Ke YiyongCarrying out magnetic reaction fields power, the size of magnetic field force is the most relevant with the gradient of magnetic field flux density.So magnetic field adds
Magnetic particle the most all can under the action of a magnetic force, deposit to exist the region of flux density gradients change.Due to magnetic field
The modulating action that manipulator is special to magnetic field, can be formed in magnetic field bar code, pattern in 2 D code shape existence magnetic flux close
The region of degree change, magnetic particle finally be deposited to the region of bar code, pattern in 2 D code under the action of a magnetic force, thus
Define bar code based on magnetic particle, the pattern of Quick Response Code, as shown in Figure 4.In figure, arrow represents magnetic particle and receives
The direction of magnetic field force, it is seen that magnetic particle all can area deposition above high-permeability material, ultimately form magnetic particle
Pattern.In the diagram, it is seen that magnetic flux distribution presents graded, at the upper surface certain altitude model of high-permeability material
Enclosing magnetic flux density to increase, low magnetic permeability material upper surface certain altitude scope magnetic flux density reduces.Diverse location magnetic from magnetic field
Property magnetic force suffered by particle scattergram visible, the region magnetic force that graded in magnetic flux density is big is relatively big, and at magnetic flux
It is less that density gradient changes little region magnetic force.I.e. in the range of the upper surface certain altitude of high-permeability material, magnetic particle is received
The magnetic field force arrived is less, and the magnetic field force that magnetic particle receives in the range of the upper surface certain altitude of low magnetic permeability material is relatively
Greatly.So magnetic particle in the range of the certain altitude of low magnetic permeability material surface by under the driving of magnetic field force towards both sides
High-permeability material region is moved, and final magnetic particle all can be deposited on the surface of high-permeability material.
The present invention utilizes magnetic field modulator to form the region with bar code, pattern in 2 D code in magnetic field, finally makes magnetic
Property particle deposit to this region method formed bar code, the pattern of Quick Response Code.The method is simple, efficiently, environmental protection, low cost
Honest and clean, wide to the suitability of base material, there is the biggest application potential in bar code, Quick Response Code printing field.
