Description
Technical field
The present invention relates to stator pick-up unit, specifically, relate to a kind of starter stator detector for magnetic field.
Background technology
Continuous progress along with social development and science and technology, the volume of production and marketing of automobile and social recoverable amount are more and more higher, also more and more with the starter demand of matching with automobile engine, simultaneously more and more stricter to product quality requirement, the application of various online mistake proofing technology has had wide prospect of the application.The magnetic pole of starter stator assembly extensively adopts iron oxide as raw material, and effect is to provide magnetic field for starter (direct current generator).When this material is applied on starter, start to be not possess magnetic field, must lead to magnetizing equipment it is magnetized, and two problems that are prone to most when magnetization are: not magnetization of one; Two, direction of magnetization is contrary.For solving the mistake proofing problem of these two aspects, by operating personnel, with instrument, manually detected completely in the past,, also there is undetected error inspection simultaneously in inefficiency like this, affected with uncontrollable factors such as moods by peopleware and restrict, cause these two problems to can not get solving thoroughly.
Summary of the invention
The present invention is directed to the device of existing stator detection or the inefficiency that manual method exists, the shortcoming that accuracy rate is not high, provides a kind of starter stator detector for magnetic field to address the above problem.
The solution of the present invention is by such realization: a kind of starter stator detector for magnetic field, comprise conveying belt, described conveying belt is provided with stator and rotor assembling equipment, also comprise the delivery platform being arranged on conveying belt, described conveying belt place is provided with detection segment, and detection segment side is provided with stator pick-up unit.
The ultimate principle of this law scheme is: the high feature of flowing water hookup wire robotization efficiency by stator and rotor, is installing them, but when not loading onto brush, carry out the detection of stator field, thereby can realize the effect that streamline detects.
In the present invention, as further improvement, described stator pick-up unit comprises monitor station, and is arranged on the expansion link on monitor station, and described expansion link end position is provided with magnetic test coil, and described magnetic test coil is connected with PLC system and simulating signal display screen.
Above-described described magnetic test coil at least comprises four groups of coils, and the winding direction of described adjacent two coils is contrary.
The technology ultimate principle of the invention described above scheme is: it is the end face close to field frame assembly by a kind of measuring coil that stator detects principle, according to the requirement of product, as level Four product adopts four groups of coils, and sextupole adopts six groups of coils, the winding direction of adjacent two coils is contrary, when coil can produce induction electromotive force during near stator field in coil, this induction electromotive force amplifies to accept the simulating signal of processing by amplifying circuit, according to the result of collection of simulant signal, provide the judgement of magnetic direction and intensity, thereby guaranteed whether the product that flows through this pick-up unit meets the requirements, reach the object of mistake proofing.
In the present invention, as further improvement, described stator pick-up unit is also connected with warning device, by warning device, can point out error message, allows staff stop in time streamline.
As the further scheme of foregoing invention, described detection segment place is also provided with gear shifting device, and described gear shifting device is connected with PLC system.The effect of gear shifting device is stopping of better limit transport platform and starts, and it can be a kind of mechanical gear shifting device, can be also electronic induction gear shifting device.
The invention has the beneficial effects as follows:
1. automaticity of the present invention is high, can in streamline, detect rapidly to stator field direction by the simplest method, and efficiency is high more than 30% compared with prior art, and accuracy rate is high more than 20%.
2. the present invention is easy to make, can in existing streamline, add making.
3. the present invention is simple in structure, and cost of manufacture is low, is convenient to the industry and promotes the use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Parts title and sequence number in figure:
Stator 1, rotor 2, conveying belt 3, detection segment 4, magnetic test coil 5, expansion link 6, monitor station 7, warning device 8, gear shifting device 9, delivery platform 10.
Embodiment
Below in conjunction with drawings and Examples, describe the present invention, following examples explain with invention optimal effectiveness.
Embodiment 1:
As shown in Figure 1-2, this starter stator detector for magnetic field, comprise conveying belt 3, conveying belt 3 is provided with stator 1 and rotor 2 mounting equipments, and holds the delivery platform 10 that assembles stator 1 and rotor 2, conveying belt 3 places are provided with detection segment 4, detection segment 4 sides are provided with stator pick-up unit, and stator pick-up unit comprises monitor station 7, and are arranged on the expansion link 6 on monitor station 7, expansion link 6 end positions are provided with magnetic test coil 5, and magnetic test coil 5 is connected with PLC system and simulating signal display screen; In the present embodiment, magnetic test coil 5 is for detection of level Four product, therefore has four groups of coils, the winding direction of adjacent two coils is contrary, on delivery platform 10, be also provided with warning device 8, and detection segment 4 places are provided with gear shifting device 9, warning device 8 is all connected with PLC system with gear shifting device 9.
During operation, first by after stator 1 and rotor 2 assemblings, put into delivery platform 10, when delivery platform 10 runs to detection segment 4 subsequently, by gear shifting device 9, stopped to get off, with rear telescopic rod 6, start stretching motion, magnetic test coil 5 extends stator 1 end, magnetic test coil can produce induction electromotive force during near stator 1 magnetic field in coil, thereby induction electric shows after will definitely signal amplifying by circuit in simulating signal display screen, if it is qualified to detect, signal is sent to PLC system, thereby PLC system is controlled gear shifting device 9 clearance delivery platforms 10; When magnetic test coil 5 finds that simulating signal is undesirable, signal is sent to PLC system and warning device 8, warning device 8 gives the alarm, 3 operations of PLC system halt conveying belt.
