  • Patent number: 6891183
    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.

  • Patent number: 6750446
    Abstract: An ultrasonic-welding apparatus, which can automatically achieve measurement of the face-deflection the work piece after welding and during the welding of work pieces, such as a reel for a magnetic tape. The ultrasonic-welding apparatus includes: a cradle, onto which two types of work pieces to be welded are mounted in piles, and which can rotate around an axis vertical to the welding surface of a workpiece to be welded; a welding horn, which carries out welding using ultrasonic vibration wherein the two work pieces are sandwiched by the cradle; and a transmission-type laser sensor which measures the fixed part of the work pieces, after welding, by the irradiation of laser light which runs parallel to the welding surface, wherein the workpieces are rotating on the cradle and the welding horn is apart from the work pieces.
