Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic welding, in particular to an ultrasonic metal welding device with an automatic driving mechanism. Background Art

[0002] Ultrasonic welding is a welding method that uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the two surfaces of the objects are rubbed against each other to form a fusion between the molecular layers. During the welding process, the ultrasonic generator converts the current into high-frequency electrical energy, which is converted into mechanical motion of the same frequency again through the transducer. These mechanical motions are then transmitted to the welding head through a set of amplitude-changing rod devices that can change the amplitude. The welding head transmits the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction to melt the material. The existing ultrasonic welding equipment can basically meet the daily use needs, but there is still a problem. The shortcomings of the ultrasonic metal welding equipment are as follows: first, the existing equipment needs to manually use a clamping tool to fix the workpiece on the processing platform before welding, which increases the labor cost of equipment processing and affects the efficiency of welding processing; second, the welding head in the existing equipment has limited freedom, and the inclination angle of the welding head cannot be adjusted according to the shape of the welding part of the workpiece, which is difficult to meet the complex actual production needs and affects the practicality of the equipment; third, the existing equipment has a single functionality and cannot clean the welding part before processing.
