Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding technology, and in particular to a multi-functional welding head for an ultrasonic welding machine used in SMT workshops. Background Technology

[0002] SMT ultrasonic welding machines are high-efficiency welding devices specifically designed for surface mount technology (SMT). They achieve precise welding between electronic components and PCB boards through ultrasonic vibration. The core principle is to utilize high-frequency ultrasonic energy to generate frictional heat at the welding interface, causing localized melting of the material and forming stable intermolecular bonds. This offers advantages such as high welding speed, high precision, and no need for flux, making it particularly suitable for welding tiny, precision electronic components. Traditional ultrasonic welding head replacement requires disassembling screws and repositioning, taking 3-5 minutes, and has low repeatability. For the multi-tasking scenarios in SMT workshops, there is an urgent need for a welding head structure that supports rapid replacement within 30 seconds and is compatible with multiple functions.
