Description
Technical field
The present invention relates to paper money counter technical field more particularly to it is a kind of have plus magnetic function bill counter magnetic head.
Background technology
The magnetic head of paper money counter is otherwise to the knowledge of banknote magnetism on domestic and international market at present：
（1）Detection to banknote metal wire magnetism generally uses a big magnetic head, this big magnetic head is only to metal wire signal
There is output, crown word number magnetism and ink magnetism are not exported；
（2）Magnetic to paper money number and ink magnetism detection, generally uses many only small magnetic heads, this small magnetic head to exist
Crown word number magnetism can be detected when not powered, but only could detect other printing ink signals, and magnetic when power-up
The voltage of head power-up needs to add different voltage to different position printing ink signals, amplifies strategy using different signals.
At present semiconducting-magnetic-head plus magnetic be the bottom of semiconductor indium antimonide in advance to semiconductor provide carrier deflection
Magnetic field, magnet one are scheduled on inside magnetic head rearward far from the faces R position, and magnet is usually the magnet of one piece of blockage shape.Work as semiconductor
Carrier causes to generate variation to magnetic field itself and make carrier deflect and change generation electric current when encountering external magnetic field
Variation.
The existing big magnetic head of the coil used and small magnetic head are used according to the variation range difference of signal frequency itself
Different structures.Big magnetic head is magnetic using the relatively low metal wire of the anti-interference detection frequency of double slit designs, and small magnetic head is using single
Small―gap suture design to carry out the more higher ink of frequency acquisition magnetic.The characteristics of this two classes magnetic head is all that requirement bank note itself is pre-
First already provided with the magnetic possibility that can just have and generate signal output.So paper money counter is all necessary on the runway before bank note inspection
Give the bank note abundance passed through enough magnetism in advance.A magnetic can also be generated at the faces magnetic head R by the method powered up to magnetic head
, but the signal of bank note one side can only be run out of, bank note turn-over signal is almost just without and voltage range is narrow slightly high
A bit（30V）Magnetic head is just saturated, and magnetic head is electrified for a long time generation heat, seriously affects head life.
The coil type of foreign countries' production adds magnetic magnetic head also to make by the way of adding magnetic at the faces magnetic head R other than expensive
Coil puts a piece of magnet because outside changes of magnetic field generates signal above one single magnet passage.In the table of heads contact bank note
Face（The faces R）Only magnet is exposed, and the iron core of magnetic head itself is ensconced below magnet.Principle is magnetic field of magnets generation above
Magnetic field is transmitted to following iron core gap and generates variation, then the coil by being wound on 2 groups of series aiding connections on magnetic core when variation
Generate signal.Feature can run out of all bank note signals simultaneously.The disadvantage is that the consistency feature of signal itself is unstable, signal height
The drift of point interval is very big, and paper money counter is easy wrong report.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of bill counter magnetic heads for having and adding magnetic function.
The technical solution adopted by the present invention is：
It is a kind of that there is the bill counter magnetic head for adding magnetic function comprising shell, shell are equipped with opening, shell along its length
Opening in be equipped at least one set and extend the magnetic core of opening, the magnetic core includes the two of a piece of core sheet and core sheet
Side is arranged with magnetic seam copper coin, side chip board, flat thin magnet and the shielding piece being bonded successively from inside to outside, the polarity of the flat thin magnet
Perpendicular to the faces magnetic head R, and the flat thin magnet polar orientation having the same of core sheet both sides, it is arranged on the side chip board
Coil windings, the axis extending direction of the coil windings are the upper and lower end face extending direction along side chip board, core sheet two
The coil windings reverse parallel connection of side.
The shell is plastic shell.
The integral multiple that the piece number of the flat thin magnet is 2.
The part that plastic shell is extended in the upper end of the shielding piece fits in the faces magnetic head R.
The shell both sides are additionally provided with the screw extended into shell, and the screw end is close to shield piece, and will shielding
Piece, flat thin magnet, side chip board, magnetic seam copper coin, core sheet are bonded to each other closely.
The invention also includes wiring board, the wiring board includes amplifying circuit and AD sample circuits, and the wiring board is located at
The inner cavity of shell, amplifying circuit are amplified magnetic head signal waveform, after AD sample circuits are to the amplification of the output of amplifying circuit
Magnetic head signal waveform carry out AD samplings, AD sample circuits by wiring board be equipped with standard plug-in unit interface and winding displacement it is external defeated
Go out.
The present invention uses above technical scheme, on the surface that magnetic head is contacted with bank note（The faces R）Place establish one it is stable
Magnetic field section disturbs the magnetic field being had built up at the faces magnetic head R when outer synchronous signal is come in, in magnetic
Synchronous inductive signal is generated in head core sheet both sides respective coil windings, since coil windings are reverse parallel connections just sense
Induction signal cancelled out each other play the role of it is jamproof.Magnetic when asynchronous signal is come in being had built up at the faces magnetic head R
The sequence that field disturbs is different, to generate nonsynchronous induction letter in the respective coil windings in magnetic head core sheet both sides
Number, since coil is that still have output after reverse parallel connection just inductive signal is subtracted each other.The present invention is unlike former magnetic head
It was so that magnetic head is generated signal by the remanent magnetism of banknote itself in the past, the present invention is dry by the magnetic field that magnetic particle has built up magnetic head
It disturbs to generate signal.Banknote need not magnetize again when the present invention carries out money-checking and sensitivity greatly improves.
Description of the drawings
