A kind of trans-printing type children teaching aid based on electrically conductive inkTechnical field
The invention provides a kind of trans-printing type children teaching aid based on electrically conductive ink, belong to children's early education articles for use technologyField.
Background technology
At present, the positive every field infiltration of microelectric technique, conductive rendering technique arises at the historic moment as a kind of new and high technology.Electrically conductive ink can be plotted in PET film by such as film switch circuit version, then by printed film and decorative art facePlate is formed by combining；Have the advantages that simple in construction, good appearance, environment resistant excellent, service life are long, be widely used in electricitySub- toy, teaching aid, measurement apparatus and Medical Instruments etc..Ink protracting circuit plate technique is simple, efficiency high, but also saves metalCopper, is to reduce an effective way of microelectronic product cost, and other, which also have, is used in contact-sensing panel, draws flat fineCable, low-cost solar battery, liquid crystal display electric current and infra-red detection sensing element etc., in microelectronicUsing being diversified.The conventional fabrication method of the said goods is with conductive charcoal slurry or silver paste, only two kinds of black or whiteDull admittance, by the way of half tone is drawn；Mode drawn due to half tone yielded poorly, cost it is high, can not produce in enormous quantities.WithThe development of modern science and technology, market needs colorful electrically conductive ink, and water-soluble conducting ink can by the way of various draftings,Production efficiency can be greatly improved, it will by the most attention of people, because its high conductivity flexibly can should with low conductivityWith improving the flexibility of design, it is adaptable to various new electronic equipment.From RFID tag to " intelligent clothing ", unique chemistrySystem maintains the low conductivity under extraneous stress, and wide in range condition of cure and high flexibility has supported many inexpensive pedestalsApplication.
At present in children's early education field, it is necessary to teach children to recognize various toys, and children are allowed to be familiar with themCry, these current teaching aids are plane pattern print product mostly, or electronic pictures form.By allowing outlook on childrenExamine, listen to, to play a part of recognizing these animals.But these children teaching aids can not realize interaction at present, children are in studyDuring can not participate in person, therefore education effect it is bad, the impressionable quarter of children.If can be by waterborne conductive oilInk is combined with children's early education apparatus, then can solve the problem that above technical barrier.
The content of the invention
The invention provides a kind of trans-printing type children teaching aid based on electrically conductive ink, of the prior art ask is solvedTopic, the teaching aid structure is simple, novel, and children can be allowed oneself to be participated in during study, deepens the impression of children, improves and learnEnjoyment is practised, the effect taught through lively activities is played.
Realize technical scheme that above-mentioned purpose of the present invention used for：
A kind of trans-printing type children teaching aid based on electrically conductive ink, it is described at least including button cell and sound chipTrans-printing type children teaching aid be made up of transfer blade and substrate, described button cell and sound chip is fixed on substrate,The circuit A in cartoon pattern shape is printed with electrically conductive ink on substrate, button cell and sound chip are electrically connected in circuit A,Absent region is provided with described circuit A；Described transfer blade is from top to bottom followed successively by transfer paper, transparent abscission layer, inkLayer and adhesive layer, described ink layer are the circuit B, the circuit B in identical cartoon pattern-like printed using electrically conductive inkMatch, ink layer and adhesive layer tear-off can be got off in described transfer blade, by ink layer with the absent region on circuit AIt is attached to adhesive layer on substrate in corresponding absent region, now circuit A and circuit B compositions loop, sound chip carries out sounding.
Small bulb is additionally provided with described substrate, the small bulb is fixed in circuit A, when circuit A and circuit B is constitutedDuring loop, small bulb can light.
