Description
Technical field
The present invention relates to magnetic microparticle chemiluminescence field, more particularly, to chemical luminescence detector magnet fixed plate pole of magnet
Property detecting system.
Background technology
In chemical luminescence detector, usually magnetic bead is adsorbed using magnet.Multiple magnet are fixed on plastic material system
Into magnet fixed plate on, sealant pouring and sealing is to improve magnet resistance to corrosion afterwards（Not plus magnet a few minutes of coating can be
Corrosion in air）.In order to meet the requirement of adsorption function and processing technology, square is often made in magnet cross sectional shape.Section
Shape for the magnet of square have the advantages that saving space, easy to manufacture, adsorption effect it is good, but by multiple above-mentioned shape magnet
It is assemblied in magnet fixed plate after encapsulating encapsulation, to each magnet polarities installation after assembling, whether correct detection difficult is larger,
Tracing it to its cause is：1st, tens magnet need to be assemblied in one piece of magnet fixed plate according to the polarity of setting, for example, first row
Magnet needs N poles to need S poles towards outside towards outside, the magnet of second row, and the 3rd row's the first two magnet needs S poles outside
Side and magnet afterwards needs N poles towards outside.But due to waiting magnet of cube structure except two opposite faces have
Beyond opposite polarity, the opposite side of another two also has two faces to possess two kinds of polarity of NS, if by the two sides during assembling
Polarity is to towards outside（Or interior survey）It can then seriously affect using function.2nd, the magnetic strength of magnet is not easy to detect；Commercially available measurement
The device of magnet magnetic strength such as Tesla meter, cost is higher and can not agree with magnet fixed plate production assembling actual condition completely
Detection.
In order to avoid magnet polarities loading error, two ways is taken at present：First way, uses a known fixed
The magnet of polarity, identifies N, S polarity as standard magnet；By the way that standard magnet is carried out one by one with the magnet after assembling respectively
Absorption, the principle attracting according to homopolarity mutual exclusion, heteropole are detected, while to be felt repulsive force or be attracted the size of strength,
To prevent the assembling of magnet side face outwardly.Therefore, this detection mode is easy to obscure, and causes detection error.Second of side
Formula, before magnet is loaded magnet fixed plate, operating personnel is using above-mentioned standard magnet to each magnet one to be assembled
One carries out polarity identification, after the magnet to be assembled for then determining polarity loads magnet fixed plate corresponding aperture position, uses special glue
Hole position is sealed.But if there is operation error or magnet polarities identification mistake, the assembling of magnet fixed plate in magnet cartridge during matching somebody with somebody
After the completion of then can not be correctly identified to whether magnet polarities direction assembles, detectivity is low, however it remains security risk.
The content of the invention
Present invention aims at a kind of chemical luminescence detector magnet fixed plate magnet polarities detecting system is provided, electricity is utilized
Gas principle detects the new approaches of Automatic manual transmission, realizes the correctness for ensureing assembly technology, improves detection efficiency and detectable degree.
To achieve the above object, the present invention takes following technical proposals：
Chemical luminescence detector magnet fixed plate magnet polarities detecting system of the present invention, including the detection of multiple magnet polarities
Unit, multiple magnet polarities detection unit structures are identical, by Hall element H, light emitting diode D, current-limiting resistance R structures
Into；The power input of the Hall element H is connected with DC power anode, the ground terminal of Hall element H and the direct current
Source anode connection, the detection voltage output end of Hall element H are connected with the light emitting diode D anode, and light emitting diode D is just
Pole is connected by the current-limiting resistance R with DC power anode.
The invention has the advantages that realizing the quick detection of magnet fixed plate magnet polarities, and magnet magnetic can be accurately judged to
Whether property intensity is qualified.Meanwhile the configuration of the present invention is simple, easy to operate, detection efficiency is high.
Brief description of the drawings
Fig. 1 is the circuit diagram of the present invention.
Fig. 2 is the magnet polarities detection process FB(flow block) of the present invention.
Embodiment
Elaborate below in conjunction with the accompanying drawings to the embodiment of the present invention, the present embodiment using technical solution of the present invention before
Put and implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, chemical luminescence detector magnet fixed plate magnet polarities detecting system of the present invention, including it is more
A magnet polarities detection unit 1, multiple 1 structures of magnet polarities detection unit are identical, by Hall element H, luminous two
Pole pipe D, current-limiting resistance R are formed；The power input of the Hall element H with（Pin 1）5V DC power anodes connect, Hall
The ground terminal of element H（Pin 3）It is connected with the 5V DC power cathodes, the detection voltage output end of Hall element H（Pin 2）
It is connected with the light emitting diode D anode, the cathode of light emitting diode D passes through the current-limiting resistance R and 5V DC power anodes
Connection.
As shown in Fig. 2, system is powered using 5V DC power supplies, n magnet polarities detection unit 1 is rear defeated using being connected in parallel
Go out, ensure not influence each other between each passage, the numerical value of n is equal with the magnet quantity in magnet fixed plate to be detected；Current limliting electricity
Hinder R and be used for size of current in limiting circuit, avoid the excessive damage light emitting diode D of electric current.
In practical set operation process, n magnet is assembled in magnet fixed plate first, using special glue by magnet
Sealing；Then the magnet fixed plate for assembling completion is positioned in the fixed frame of magnet fixed plate, n magnet polarities detection is single
Hall element H in member 1 is corresponded with n magnet positions in magnet fixed plate, each magnet cartridge is matched somebody with somebody the detection of polarity
It does not interfere with each other, being finally powered carries out magnet polarities detection.
Testing principle is：Each magnet in magnet fixed plate influences self-position regional magnetic field, changes each corresponding position
The detection voltage output terminal potential of place Hall element H is put, so as to determine the conducting and disconnection of light emitting diode D.H pairs of Hall element
If answering, test position detects magnet and polarity is correct, and the detection voltage output end of Hall element H is low level, light emitting diode
Luminous instruction is given in D conductings；If Hall element H corresponds to test position and is not detected by magnet or magnet polarities mistake, Hall element H
Detection voltage output end be high-impedance state, light emitting diode D open circuits and extinguish；So as to according to the shining of light emitting diode D, put out
Go out and reach the purpose that detection magnet polarities and magnet whether there is.
