Abstract
An ultrasonic-welding apparatus including: a cradle, onto which two work pieces are mounted, and which can rotate around an axis vertical to the welding surface of the work pieces; a welding horn, which carries out welding using ultrasonic energy while sandwiching the two work pieces between it and the cradle; a transmission-type laser sensor which measures the fixed part of the work pieces after welding, rotating on the cradle, in the condition that the welding horn is apart from the work pieces after welding; and an optical sensor including a light-emitting part, a light-receiving part, a connecting part on which the light-emitting and light-receiving parts are mounted, and an adjusting part that rotates the connecting part around two axes.
