Description
Technical field
The present invention relates to the online device for detecting particles of a kind of enamel-covered wire, belong to on-line measuring device technical field.
Background technology
At present, namely enamel-covered wire particle paints knurl, Qi Pao, numb skin, is a kind of blemish more common in Production of Enamel Wires, relates to factors, as insulated paint impurity, production scene dust, bare wire blemish, paint film scraping etc. all can cause enamel-covered wire particle.Enamel-covered wire particle can cause the dimensions of enamel-covered wire to change, and the elasticity of enamel-covered wire, enamel-covered wire mechanical performance, electric property is changed, affects the normal performance of electric product, reduces the reliability of electric product.
At present, known enamel-covered wire circle line surface particle detection mode has two kinds.
The first is mould detection, specifically entangle the enamel-covered wire in advancing with nib slightly larger than the enamel-cover mould of tested enamel-covered wire external diameter, when there is particle in enamelled wire surface, particle can drive enamel-cover mould, after enamel-cover mould, interlock has transmission device and photoelectric detective circuit, and photoelectric detective circuit exports useful signal and then represents and particle detected.But the nib size of enamel-cover mould can not change in real time, when enamelled wire surface have comparatively macroparticle time, particle cannot easily cause paint film scratch or broken string by enamel-cover mould; When particle is less, enamel-cover mould cannot be driven again, also effect this kind of mode such as the patent No. just not having detection is disclose a kind of enamel-covered wire on-line measuring device in the patent of 201220568546.3, comprise and detect mould, induction installation and recording instrument without paper, described induction installation is connected with recording instrument without paper, also comprise the switch board of built-in computer equipment, described recording instrument without paper is connected to computer equipment by data wire.The patent No. is also had to be disclose a kind of device for detecting particles in the patent of 201220420925.8, comprise bolt shaft, fixed block, detection of particles die holder, detection of particles mould, regulating shaft and microswitch, described detection of particles mould is placed on detection of particles die holder, freely up and down slide, described detection of particles die holder and microswitch are arranged on regulating shaft body, detection of particles mould is connected with microswitch, described regulating shaft one end is stretched out, through described fixed block, described bolt shaft is passed from the opposite side of fixed block; Described microswitch occurs to touch alarm; Described regulating shaft is vertical with bolt shaft; Described regulating shaft and bolt shaft are bolted on fixed block.The maximum weak point of which is that need to vary in size will change enamel-cover mould at any time according to enamel-covered wire specification, these factors limit applying of the method.
The second is that acceleration transducer principle detects, the contact metal film specifically having " V " v notch v with two blocks the enamel-covered wire in advancing relatively, micro-ly between two contact metal films to stagger, all with advance in enamel-covered wire vertical, when there is particle in enamelled wire surface, particle can touch contact metal film, contact metal film interlock is fixed with the Elastic clamping plate of acceleration transducer, acceleration transducer can export an acceleration signal, and this semaphore can be changed into a particle signal and export by follow-up circuit.This kind of mode as the patent No. be 201120058698.4 patent discloses the online particle detector of a kind of enamel-covered wire, comprise Circuits System, Elastic clamping plate, contacting metal blade, outgoing line guide wheel, incoming wire guide wheel, support, pressing plate, bolt, steel edge film trap, it is characterized in that, described contacting metal blade free is placed on width slightly larger than in the steel edge film trap of contacting metal blade thickness, described Elastic clamping plate clamps contacting metal blade, described Elastic clamping plate is connected with Circuits System, the guide groove of described incoming wire guide wheel, space between two panels contacting metal blade, the guide groove of outgoing line guide wheel is positioned on same straight line and same level line.In which, vibration on the line of enamel-covered wire, to vibration sensing, can be mistaken for particle, reduce the accuracy of system by acceleration transducer itself; " V " v notch v of contact metal film, can not be suitable for the enamel-covered wire of different size, and can only be similar to 4 points to the line of often kind of specification and contact with enamel-covered wire, undetected situation is many; Though the breach of contact metal film does round and smooth process, because of and enamel-covered wire perpendicular contact, frictional force has scraping to enamel-covered wire appearance greatly, detection while injury is created to enamel-covered wire, make this kind of mode be difficult to promote.
Summary of the invention
The object of the invention is to the deficiency for existing two kinds of detection modes, provide a kind of brand-new on-line checkingi enamelled wire surface with or without the device for detecting particles of particle, so that the surface appearance of on-line checkingi enamel-covered wire better.
