US 6,891,183 B2 · Ultrasonic-welding apparatus, optical sensor and rotation sensor for the ultrasonic-welding apparatus

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.

Dependent claims

An optical sensor for an ultrasonic-welding apparatus comprising:

a light-emitting part which emits a beam of light to an object;
a light-receiving part which receives the beam of light emitted from said light-emitting part and affected by said object;
a connecting part, onto which the light-emitting part and said light-receiving part are mounted;
an adjusting part, which rotates said connecting part around two perpendicular axes;
and
an inspection unit which generates a light-receiving pattern based on said light received by said light-receiving part and detects a lighted part and a shaded part from said light-receiving pattern, and said inspection unit inspects an inclination of an axis of said light emitted from said light-emitting part, and
wherein said object is flanges of a reel formed by said ultrasonic-welding apparatus.
