Abstract:
An ultrasonic adhering method for bringing a horn of an ultrasonic oscillator in contact with a sheeted resin material while the sheeted resin material is overlaid on an object to be adhered and oscillating the horn ultrasonically, wherein a temperature of the horn is sensed, and an oscillation time in a state of the horn being in contact with the sheeted resin material is set to be in a negative correlation with respect to the temperature of the horn, wherein the negative correlation is expressed by the following formula:Y=Bâˆ’AX wherein Y is the oscillation time, X is the temperature of the horn, A is a positive value expressing an inclination and a coefficient of the formula for controlling the oscillation time, and B is the oscillation time when the temperature X of the horn is 0, and wherein the sheeted resin material is fused to the object by controlling the oscillation time Y at the temperature X of the horn being in contact with the sheeted resin material.
