Abstract

[목적][purpose]

필름을 전극에서 끼고 구주파 용착하는 장치에 있어서, 전극에서의 고주파 용착상태를 정밀하게 검출될 수 있도록 하고, 임피던스 정합조정등을 고정밀도로 행할 수 있게 한다.In an apparatus for welding a sine wave by sandwiching a film on an electrode, it is possible to accurately detect a high frequency welding state on the electrode, and to perform impedance matching adjustment and the like with high accuracy.

[구성][Configuration]

수정 발진회로(A1)로부터의 방진출력은 전력 증폭회로(A2)에 의해서 증폭되고, 임피던스 정합회로(E)를 경유해서 시일전극(4)에 부여된다. 시일전극(4)에 부여되는 고주파 전력은 부유용량(△C)을 통해서 센서(검출회로)(30)로 추출되고, 다이오드(D1)에서 정류 검파되며, 콘덴서(C1)에서 평활화되어서, DC전압계(31)에 직류 전압으로서 표시된다. 이 DC전압계(31)에 표시되는 직류전압은 시일전극(4)과 접지와의 사이의 고주파 전압(Vo)와 비레한다. 임피던스 정압회로(E)의 가변 콘덴서(Vc)의 용량을 조정할 때, DC전압계(31)의 표시전압이 최대가 되도록 하므로서, 최량의 고주파용착을 행할 수가 있다.The anti-vibration output from the crystal oscillation circuit A1 is amplified by the power amplifier circuit A2 and is provided to the seal electrode 4 via the impedance matching circuit E. The high frequency power applied to the seal electrode 4 is extracted to the sensor (detection circuit) 30 through the stray capacitance DELTA C, rectified and detected by the diode D1, and smoothed by the capacitor C1, so that the DC voltmeter It is shown at 31 as a DC voltage. The DC voltage displayed on the DC voltmeter 31 is similar to the high frequency voltage Vo between the seal electrode 4 and the ground. When adjusting the capacitance of the variable capacitor Vc of the impedance constant voltage circuit E, the display voltage of the DC voltmeter 31 is maximized, so that the best high frequency welding can be performed.
