Description

Spooling equipment hinder line detector

Technical field

The present invention relates to the electric machine winding detection field, particularly a kind of spooling equipment hinders line detector.

Background technology

Winder is a kind of linear object to be wound into machine on the specific workpiece, is usually used in the production of electromechanics trade.According to the difference of workpiece to be wound, the mode of its coiling has two kinds: loose around; Directly coiling.Wherein, fall apart around being exactly to use winder enameled wire to be wound on the specific winding mould, after the coiling moulding, winding and winding mould are separated, again by artificial stator or rotor tabling, i.e. rule with winding and motor; Directly coiling is to use winder that enameled wire is wound on cover to have on the stator or rotor of insulating material, need not the manual wire embedding.

Because directly winding method is directly enameled wire to be wound on stator or the rotor, removes wire insertion technology from, its automaticity is higher, and productive rate is high, and has reduced cost of labor.But, when carrying out the straight line coiling, because the high-speed cruising of winder nuzzles up on the parts of enameled wire and equipment and stator or the rotor core and easily causes the paint film of enameled wire impaired, cause the motor turn-to-turn short circuit, finally cause not turning round or burning of motor.This all is disadvantageous concerning the cost of enterprise and quality, therefore, be badly in need of a kind of can real-time detection apparatus, when the enameled wire shutdown of at once reporting to the police when paint film is impaired in winding process, be convenient to the field personnel and process.

Summary of the invention

The object of the present invention is to provide a kind of line detector of hindering of spooling equipment, the paint film that can detect in real time enamel-cover money is impaired, and the operation of control winder stops and/or reporting to the police.

For realizing above purpose, the technical solution used in the present invention is: a kind of spooling equipment hinder line detector, comprise testing circuit, an end of enameled wire is communicated with testing circuit on the enameled wire loop, the other end enters winder and carries out coiling, described testing circuit, winder are connected with the positive and negative electrode of power supply respectively, and testing circuit outputs signal to winder and controls the operation of winder and stop and/or reporting to the police.

Compared with prior art, there is following technique effect in the present invention:

This detection mode response is fast, in case there is the paint film of enameled wire impaired, between enameled wire and the winder with regard to conducting, positive source passes through to be communicated with power cathode behind testing circuit, enameled wire, the winder, form the loop, just there is electric current therefrom to flow through in the testing circuit, by feeding back signal to winder, makes it stop coiling and/or warning; This circuit is simple simultaneously, easily realizes.

Embodiment

Below in conjunction with Fig. 1 to Fig. 2, the present invention done being described in further detail:

Consult Fig. 1, a kind of spooling equipment hinder line detector, comprise testing circuit 10, an end that is positioned at the enameled wire A on the draw drum 20 is communicated with testing circuit 10, the other end enters winder 30 and carries out coiling, described testing circuit 10, winder 30 are connected with the positive and negative electrode of power supply 50 respectively, and the operation that testing circuit 10 outputs signal to winder 30 control winders 30 stops and/or reporting to the police.Among the present invention, in case have paint film impaired on the enameled wire A, enameled wire A and winder 30 are conducting, the positive pole of power supply 50 is communicated with power supply 50 negative poles by testing circuit 10, enameled wire A, winder 30, form the loop, just have electric current in the testing circuit 10 and flow through, when testing circuit 10 detects electric current, can output signal to winder 30, it is quit work and/or report to the police, so that the field personnel processes.

Ingenious part of the present invention is, enameled wire A is similar to detect with the cooperation of winder 30 be provided with a switch in the loop: be equivalent to switch closure, loop conducting when contacting with winder 30 when enameled wire A paint film is impaired; A is normal when enameled wire, and insulation between the winder 30, is equivalent to switch and disconnects, the loop cut-off.

When winder 30 carries out quick coiling, often occur treating that the stator of coiling or rotor 40 collide with enameled wire A, also be easy to cause the paint film of enameled wire A impaired.Although be arranged with insulating material on stator to be wound the line or the rotor 40, here only in the place that stator or rotor 40 need to wind the line insulating material is set, other parts all do not arrange insulating material, the impaired place of paint film that enameled wire A therefore also can occur once in a while contacts with the part that stator or rotor 40 do not arrange insulating material, also can cause the motor turn-to-turn short circuit, as preferred version of the present invention, described stator or rotor 40 link to each other with the negative pole of power supply 50, further guarantee the reliability of coiling process.

In detection, because the positive pole of power supply 50 is communicated with power supply 50 negative poles by testing circuit 10, enameled wire A, winder 30, form the loop, if the voltage of power supply 50 is too high, will there be certain unsafe factor, easily the staff on winder 30 next doors be caused electric shock.Therefore, as preferred version of the present invention, power supply 50 voltages that adopt here are lower.And the enameled wire A on the draw drum 20 is more, and its resistance is also larger, generally can reach the M Ω order of magnitude, in the situation that power supply 50 voltages are lower, the electric current that flows through in the testing circuit 10 is very faint.
