Description

Известен способ контрол  процесса ультразвуковой сварки, при котором в свариваемые детали волноводом ввод т колебани  с непрерывным измерением амплитуды колебаний опоры.A known method of controlling the process of ultrasonic welding, in which oscillations are introduced into the welded parts by a waveguide with continuous measurement of the oscillation amplitude of the support.

Предложенный способ позвол ет повысить точность контрол , благодар  тому, что производ т непрерывное измерение амплитуды колебаний волновода.The proposed method makes it possible to increase the accuracy of the control, due to the fact that a continuous measurement of the waveguide oscillation amplitude is performed.

Суидность изобретени  по сн етс  чертежом.Suidency of the invention is illustrated in the drawing.

Амплитуду колебаний волновода / измер ют датчиком 2, электрический сигнал которого усиливаетс  усилителем 8 и выпр мл етс  детектором 4, после чего подаетс  в сеточную сеть усилител  5, усиливающего сигнал датчика и опоры 6. При стабильной величине амплитуды колебаний волновода 1 сигнал датчика и опоры 6 будет отражать только изменение состо ни  материала при сварке, что можно наблюдать с помощью индикатора 7.The amplitude of the waveguide oscillations / is measured by sensor 2, the electrical signal of which is amplified by amplifier 8 and rectified by detector 4, and then fed to the grid network of amplifier 5, amplifying the signal of sensor and support 6. With a stable amplitude of oscillation of waveguide 1, the signal of sensor and support 6 will reflect only the change in the state of the material during welding, which can be observed using the indicator 7.

В случае уменьщени  амплитуды колебаний волновода уменьщитс  посто нное напр жение , получаемое от выпр мител  4. Это изменение напр жени , нодаваемого в сеточную сеть усилител  5 колебаний датчика и опоры 6, переведет рабочую точку в сеточной харакгеристике лампы усилител  5 в область с больщим усилением, в результате чего режим работы усилител  изменитс  и индикатор 7, не реагиру  на нзменение величины амплитуды волновода, будет отрал ать только изменение состо ни  свариваемого материала.In the case of reducing the amplitude of the waveguide oscillations, the dc voltage received from rectifier 4 decreases. This change in voltage applied to the grid network of the amplifier 5 of the sensor oscillations and the support 6 transfers the operating point in the grid characteristic of the lamp amplifier 5 to a region with a large gain, as a result, the operation mode of the amplifier will change and the indicator 7, not reacting to the change in the amplitude of the waveguide, will only reflect the change in the state of the material being welded.
