Title: ULTRASONIC WELDING DEVICE AND ULTRASONIC WELDING METHOD
Abstract:
Provided are an ultrasonic welding device and an ultrasonic welding method, whereby it is possible to avoid a defect resulting from welding a part to be welded of work piece in which there is an abnormality. The present invention is provided with: (a) a support device (35) configured so as to support a work piece (W) along a predetermined conveyance surface; (b) a welding machine including an oscillator (7) for generating a high-frequency electric signal, a transducer (8) for converting the high-frequency electric signal to a mechanical vibration, and a horn (9) to which the mechanical vibration is transmitted, the horn (9) being disposed so as to face a part to be welded of a work piece (W) supported along the conveyance surface, and the mechanical vibration being imparted via the horn (9) to the part to be welded, whereby the part to be welded is welded; (c) a detector (60) for detecting an abnormality in the part to be welded, the detector (60) being disposed further upstream in the conveyance direction of the work piece (W) than the support device (35); and (d) a protective device (70) for prohibiting the welding machine (36) from welding the part to be welded in which an abnormality is detected by the detector (60).
