Be one group of detection module to be provided with each holding frame in a fabric wheel portion, horizontal gird sets gradually along its arranged direction and organizes detection module more.
The surveyed area of described detection acquisition component is positioned at the priming paint painting process place of enameled wire.
Sparking voltage as the discharge assembly of power supply is 6 ~ 10V.
Beneficial effect of the present invention is:
1) detection system, in the present invention is only the hardware platform being linked together by circuit configurations by physical unit and form.In use, native system can coordinate the measurement and statistics that realize for voltage-to-ground with software of the prior art, but it must be noted that: the software matched with this control system is not innovative part of the present invention, neither ingredient of the present invention.
Under the acting in conjunction coordinated with software; the present invention can realize the thickness degree of enamelled wire surface paint film or even the judgement without paint section respectively; but protection of the present invention is only prolonged and to the hardware net be made up of physical unit and wire, and the improvement do not related to software and protection.
The present invention passes through said structure, using fabric wheel portion as the discharge end connecting the discharge assembly of specifying.Because enameled wire itself is directly contacted with on enamelling machine all the time, and enamelling machine is by being positioned at ground as metallic conductor, now, constitutes a whole set of circuit over the ground between the wheel body in discharge assembly, fabric wheel portion, enameled wire, enamelling machine frame and ground.Suitable voltage is released by discharge assembly, this electric current can be advanced along fabric wheel portion and the enameled wire contacted with fabric wheel portion, the ground place until submerge, thus make the voltage sampling circuit being positioned at enamelling machine frame place know the voltage-to-ground of the enameled wire that this section contacts with fabric wheel portion.Compare between the voltage-to-ground data under the normal wire enamel film thickness preset by control alarm assemblies place, can judge whether the film thickness locating this section of enameled wire meets the demands.Consider that wire enamel film thickness certainly exists thickness difference, and also may exist do not affect pole that enameled wire normally uses slightly length few paint section or without paint section, therefore by setting regular hour section requirement.Only voltage-to-ground all continuous print do not meet normal pressure drop regulation, and when this continuous time reaches the time period of setting, control alarm assemblies and get final product stopping alarm, thus impel field staff to go to observe and correct.The time period of this setting is longer, needed for reach the length without paint section or the section of paint less of warning degree also longer.
Native system, by the voltage drop detection mode of discharge type, with the fabric wheel portion of Structure deformation direct between enameled wire, ensures that discharge loss between the two drops to minimum, to promote the accuracy of final pressure drop calculation of measured data.Its accuracy in detection is promoted further with the Data Comparison effect controlling alarm assemblies.Not only detection efficiency is higher for it, and ensures in enameled wire high speed traveling process, still can accurately realize accurately detecting for the online of this enameled wire.
2), be promote further the discharge effect of fabric wheel portion as discharge end, guarantee the accuracy detecting data.This sentences the separation structure of the upper and lower fabric wheel possessing concave arc bottom land, and " clad type " realized for the enamelled wire surface of advancing at a high speed contacts effect.In other words, the fabric wheel portion of native system is the electric discharge of the direct contact of omnibearing clad type for enamelled wire surface, thus realizes the complete detection object around enamelled wire surface, and its detection accuracy is higher.
3), horizontal gird provides fabric wheel portion with unsettled arrangement.If consider that it directly contacts with fabric wheel portion wheel body, the discharge path of inevitable guiding discharge assembly produces difference, therefore, makes the discharge path of discharge assembly necessarily pass enameled wire with insulation course, to realize aforesaid enameled wire Detection results.
4), holding frame as the immobilization carrier in fabric wheel portion, its holding tank is dismountable to be connected on horizontal gird.Like this, the difference of enameled wire position, Shi Ge road and number, can pass through increase and decrease detection module, and screwed tightening oncomelania nail regulates holding frame relative to the position of horizontal gird, thus the realization enabling the race in the fabric wheel portion on it lucky is for the coated guiding effect of this road enameled wire.
5), as key monitoring position of the present invention, fabric wheel portion should be arranged in the priming paint painting process place on enamelling machine.This is because show after dropping into a large amount of energy and experimental verification, because later stage enamelled coating is all the coating quality that depends on priming paint as prerequisite.First operation place is also the painting operations of " priming paint ", often have impact on later stage enamelled coating coating effect and the dependability of enameled wire greatly.If priming paint painting process has just been painted bad, during as existed without paint section, the exposed surface of copper cash i.e. generating portion surface oxidation before entering second painting process, paint liquid surface adhesion force when causing the later stage to be painted is deteriorated, even occur that copper line surface is peeled off completely and between paint liquid, thus produce leaky when using.
Native system by detection emphasis is arranged in priming paint operation place, needed for just can meeting all the time with the enameled wire guaranteeing initially still to be in the exposed copper cash stage its film thickness when initial japanning, to stop the above-mentioned many defects of its generation.Native system is since trying out, and Be very effective, the outgoing quality of enameled wire is effectively guaranteed, and functional reliability and serviceable life all obtain remarkable enhancing.
6), the determination of the sparking voltage of the discharge assembly of power supply is particularly important: brownout, then cannot realize measurement effect; And sparking voltage is too high, then can produce comparatively big error, affect its Detection results.Native system by great many of experiments, be 6 ~ 10V is good with above-mentioned sparking voltage, thus guarantees its detecting reliability, is conducive to promoting its measuring and calculating accuracy for wire enamel film thickness.
