Method for positioning welding metal on ultrasonic welding device and ultrasonic welding device

摘要

The present invention relates to an ultrasonic welding apparatus including a method for positioning the welding object 20 in the ultrasonic welding apparatus 34 and a sonotrode 14 to which ultrasonic vibration is applied and to emit longitudinal vibration, and an anvil 16 The welding device receiving portion 19 is formed between the working surface 17 and the opposing surface 18 of the anvil 16, and the positioning device 21 for defining the welding position P of the welding object 20 The change in position (Δx) of is captured in the longitudinal direction 22 of the sonotrode 14 by the position sensor, and the application of vibration to the sonotrode 14 changes according to the change in position (Δx) Then, a change in amplitude (Δy) is performed according to the amplitude characteristic curve of the sonotrode 14.
