In addition to the brazing process, the flat inductors and external terminals are also assisted by ultrasonic welding

There are two kinds of flat coils usually used in transformers, one is pure copper coil and the other is aluminum coil. The traditional process between welding and external terminals adopts brazing, but adding additive brazing and welding will increase the cross-sectional area due to the addition of additives. , resulting in excessive electricity and heat. In the process of use, because the ultrasonic metal welding technology is superior to the brazing welding process, there is no flux and the welding current is very small, almost O. Therefore, in recent years, the flat coils of copper and aluminum transformers have adopted ultrasonic waves. Technical welding.

How to improve ultrasonic welding results

The melting point of the solder is lower than that of the material to be welded, so that the components will be welded through the intermolecular connection on their surface without being melted.

Impedance matching of ultrasonic plastic welding machine

The impedance matching of ultrasonic plastic welding machine is an important link in the ultrasonic welding process. In the process of ultrasonic processing, it is often encountered that the equipment power is insufficient. The reason is that the load of the ultrasonic power supply does not match the equivalent resistance of the transducer, resulting in the ineffective transmission of energy. At this time, impedance transformation is required. The equivalent resistance of the transducer is matched with the output impedance of the ultrasonic power through impedance transformation to ensure the transmission of energy. This is ultrasonic impedance matching. Impedance matching is also a function completed by the matching circuit. We usually The method of using output transformer or parallel capacitor.

How ultrasonic welding equipment welds lithium-ion batteries

Since its birth, plastics have become an indispensable part of people's lives due to their light weight, low manufacturing costs, and strong plasticity. Together with steel, wood, and cement, they have become the basic materials for modern economic and social development. But at the same time, the environmental problems brought by plastics have also received extensive attention from all walks of life. In recent years, my country has attached great importance to plastic pollution control, taken a series of actions, carried out a lot of fruitful work, and established a relatively complete waste plastic recycling system, which ranks first in the world in terms of waste plastic recycling.
