Microwelding technology realization principle

   Must remove first in the enamel-insulated wire welding the paint can carry on smoothly, but brings the coil product to use all is usually the string cable diameter enamel-insulated wire, lets the iron hairpin coat of paint with the traditional craft burn down welds again very is difficult frequently, because the iron quantity of heat not easy to concentrate moreover does not have the means accuracy control, the precise electronic spot welder can carry on well to the enamel-insulated wire eliminates the paint and completes the welding.

     Precise electronic spot welder this kind of function mainly realizes through one kind of special sealed end, the sealed end sticks by two piece of electric conductivity very good metal, between two metals is the insulation, only has a very small contact resistance in the acme place, the sealed end bottom end does very much smoothly smooth.When the transmission device presses the sealed end when the enamel-insulated wire, the enamel-insulated wire can enlarge unceasingly to the sealed end reacting force, achieved hypothesis when welding pressure can trigger pulse electric current, the electric current time only then several milliseconds to several milliseconds, the size has about approximately more than 100 An Bei.The electric current has flowed the sealed end acme contact resistance, can cause the contact resistance to give off heat and to produce the electric spark, this quantity of heat can remove the enamel-insulated wire coat of paint, and can pass to in the enamel-insulated wire interior copper wire the quantity of heat, removes while the coat of paint, parial currents can through burn down the coat of paint the copper wire looping-in, the copper wire also carry on give off heat, in the short-term the copper wire temperature increment and achieved in front of the melting point the fusing condition, the copper wire on formed the new melt nucleus under the pressure function with the basis under metal, the enamel-insulated wire has realized and the metal base reliable welding.

     The sealed end welding electric current pulse provides by one kind of special large capacity capacitor, its charging and discharging rapid, do not have the pollution, the cycle life to the environment are long, by reputation for this century most environmental protection one kind of new green energy. This power source controls the integrated module take the intelligence as the core, the periphery adds a control protection circuit, the main circuit uses the power semiconductor module to do adjusts the part, the control circuit use simulation automatic tracking adjustment, the soft start, limits flows modern electronic technologies and so on the protection, can display the constant voltage splendidly, limit flows the charge performance, moreover constant voltage value adjustable, realizes the electric capacity automatic charge fast after the electrostatic discharge.At the same time, the process improvement feedback circuit, lets each time output extremely be all stable.
