摘要： The present disclosure can provide for an ultrasonic welding method for a pair of workpieces. The method can include first pressing an ultrasonic welding stack against a first workpiece in the pair so that the first workpiece comes into contact with a second workpiece in the pair. The method can then provide for initiating a weld phase by outputting energy from the ultrasonic welding stack to the first workpiece. The method can provide for monitoring, with at least one sensor, a sensed parameter. The sensed parameter can be, for example, weld force and/or weld force rate of change. The method can provide for determining whether the sensed parameter has reached a predetermined level. Based on determining that the sensed parameter has reached the predetermined level, the method can provide for ending the weld phase.

摘要： An improved ultrasonic system and method. The ultrasonic stack is moved at a low, constant (or slowly varying) speed at the initiation of the welding operation, with this speed being maintained until the predetermined condition is satisfied. In some applications, this produces a higher quality weld, such as in applications involving plastic material that softens very quickly once ultrasonic energy is imparted to the workpieces being welded, which causes the force between the workpieces to decrease rapidly. Advancing the ultrasonic stack at a low speed or slow acceleration can avoid scuffing or marking of the surface of the workpiece in contact with the ultrasonic horn, decrease audible noise produced during the welding process, and improve the consistency of weld quality in such applications compared to conventional techniques.
