Problems solved by technology

However, because the ultrasonic welding head is limited by its own vibration mechanism in the process of welding different workpieces, it is very easy to cause instability in energy transmission, and then cause slippage, welding breakage, virtual welding, burning and other undesirable phenomena on the welding workpiece.

Abstract

The invention discloses an ultrasonic welding head. The ultrasonic welding head comprises a signal line, a transducer shell, a transducer precursor part, a rear connecting flange, a connecting sleeve,a front connecting flange, a welding head connecting round table, a welding head power storage part, a welding head transmitting part, a welding head working part and the like. Through the special structure design of the end face of a welding head, the problems of slipping, deformation, pseudo soldering and the like occurring in the ultrasonic welding process are solved well, so that the applicability of ultrasonic welding in the metal welding field is further improved and becomes a indispensable link in the lithium cell welding process.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an ultrasonic welding head. Background technique [0002] In the lithium battery production process, ultrasonic welding has become an irreplaceable technology in battery welding due to its unparalleled advantages such as small welding internal resistance, high efficiency, and low energy consumption. However, because the ultrasonic welding head is limited by its own vibration mechanism in the process of welding different workpieces, it is very easy to cause instability in energy transmission, and then cause slippage, weld breakage, virtual welding, burning and other undesirable phenomena on the welding workpiece. Therefore, how to make good use of ultrasonic welding has become a difficult problem in the industry, and a technology is urgently needed to make up for this deficiency. Contents of the invention [0003] The object of the present invention is to provide an ultrasonic...
