Description
Technical field
This utility model relates to a kind of smart card, and specifically one includes battery, display device and integrated circuit etc.
Electronic devices and components, complete the one-piece type smart card of preparation process by one-shot forming.
Background technology
Along with the development of science and technology, smart card is widely used in industry-by-industry, such as access card, Intelligent Recognition card, VIP
Card, bank card etc..Constantly the application demand of upgrading proposes new safety and intelligentized requirement to these smart cards.Conventional
Although smart card has the basic components such as integrated circuit, chip, antenna, but and does not contains the temperature-sensitives such as battery, liquid crystal display
Sense and pressure-sensitive components and parts, do not possess operation independent and the ability of complicated encryption.Novel intelligent card request has higher
Computing capability and the cryptographic capabilities of higher level, therefore novel intelligent calorie requirement comprises such as battery, liquid crystal display, keyboard etc. not
Once the parts in conventional smart card were occurred in, to meet function and the performance requirement of novel smart card.
The main flow production technology of the cards such as present bank card, visa card, member card is the preparation method that hot pressing is compound, i.e. exists
Under the effect of certain temperature and pressure, plastics (usually PVC) base material being loaded with different components and parts part is made to merge, shape
Become final card.In this process, the processing environment of High Temperature High Pressure frequently occurs.General PVC (present bank card,
Vip card, the main material of various member card) temperature of card lamination is in the range of 100 DEG C-140 DEG C, and pressure is left at 5-8Mpa
The right side, such temperature and pressure, it will battery and liquid crystal display equitemperature, presser sensor components and parts are caused fatal damage
Wound.Therefore, the method for heat lamination cannot be used for the production of novel smart card.
Currently also occur in that a kind of double-component resin using room temperature or low temperature (30 DEG C-60 DEG C) heating to carry out solidifying
Method.The method can solve the problem of pressure and temperature responsive type component package, but can run into inefficiency, yield rate
Low problem.Before double-component reaction resin uses, need sufficiently to mix two kinds of components, from the beginning of mixing, two kinds of components
Just having begun to reaction, viscosity becomes larger over time, needs substantial amounts of mixing, applying glue, extrusion gas in whole technical process
Bubble, laminating etc. operates.Owing to beginning to continual reaction after mixed with resin, there is constantly change in viscosity, is difficult to the most therewith
Ensure the concordance of technique, in turn result in inefficiency, the problem that defect rate is high.Institute does not the most obtain extensively
Application.Now it is badly in need of a kind of simple in construction, intensity and reliability height, smart card to prepare fast and effectively containing wiring board, electricity
Sub-components and parts, battery, the preparation method of smart card of thermo-responsive and presser sensor electronic devices and components and display device.
The patent of invention of Application No. 201510674465.X, discloses a kind of smart card the core of the card and preparation method thereof.Should
The product of patent protection is a kind of smart card the core of the card using optic-solidified adhesive directly to manufacture.Smart card the core of the card is not may finally
The product used, it is necessary to use a kind of adhesive, laminating cladding thin film or referred to as lagging on smart card the core of the card, could end form
Become spendable smart card.
On smart card the core of the card, lagging includes following technical process:
1. gluing on smart card the core of the card or thin film lagging to be pasted；
2. the thin film lagging pasted by needs aligns with the core of the card；
3. eliminate the bubble between lagging and the core of the card, pressing afterwards；
4. use UV solidification, be heating and curing or the mode that room temperature solidifies for a long time solidifies.
From the lagging technique of above-mentioned smart card the core of the card it can be seen that the preparation of smart card is not one-shot forming completes, therefore
It not integral structure, but Split type structure is by bonding and integral.On the core of the card, lagging needs more complicated operation, this
A little operations need fine operating process, during batch and large-scale production, these operations can not with manually completing,
Therefore the equipment that automaticity is higher certainly will be used to complete, thus be greatly increased equipment investment and manufacturing cost.At lagging
With the core of the card paste pressing working procedure, even need to use vacuum equipment, otherwise bubble between lagging and the core of the card is difficult to eliminate.As
Really there is bubble between lagging and the core of the card, product quality will be had a strong impact on.Split type structure the core of the card and lagging form one by bonding
The smart card of body, due between lagging and the core of the card with the presence of glue-line, in the environment of temperature and humidity changes, or due to lagging
During STRESS VARIATION and be deformed, it will cause the core of the card and the layering of lagging or peeling, cause intensity to reduce, resistance to
Mill property is poor.Additionally, due to lagging complex procedures, cause that production efficiency is low, production cost is high, yield rate is low and smart card surface not
Can the existence of the direct problem such as problem of print pattern.
Summary of the invention
The purpose of this utility model is to propose a kind of one-piece type smart card once-forming by light-cured resin and preparation thereof
Method.This smart card is structurally integrated type structure, does not contains the glue-line of lagging；In performance, one-piece type structure is not
It is easily peeled, will not deform because of the stress problem of secondary pad pasting, improve the quality of smart card.In preparation method, pass through UV
Low temperature quick shaping of the mode of adhesive curing, it is no longer necessary to each operation of lagging, eliminates the loaded down with trivial details technique of lagging, saves
Manufacturing cost, improves production efficiency and yield rate.
A main application for this type of smart card is Intelligent Bank card, and ISO 7810, ISO 7813 is to bank card
Thickness done strict restriction, its scope is 0.76 ± 0.08mm, the thickness of the smart card of non-integral type the most on the market
Generally higher than equal to 0.84mm, in the upper limit of bank card standard, its application is restricted.For of the present utility model one
