Ultrasonic Harness Welding Machine
Ultrasonic Harness Welding machine uses the principle of ultrasonic high-frequency vibration friction to convert the energy of ultrasonic vibration into frictional energy and transfer it to the metal surface to be welded.
Product description:
Ultrasonic Harness Welding machine uses the principle of ultrasonic high-frequency vibration friction to convert the energy of ultrasonic vibration into frictional energy and transfer it to the metal surface to be welded. When the friction generates heat and pressure is applied to it, the metal structural molecules are fully activated to form the fusion between molecular layers. Ultrasonic Harness Welding Machine is easy to operate and safe to use. It is usually used for similar welding of metal. The built-in electronic protection circuit of the machine can carry out single point or multi-point welding on non-ferrous metals. It is widely used in battery and hardware industry, especially in lithium power battery, harness industry and other applications.

Features
Ultrasonic Harness Welding machine is an ideal process for welding ductile sheet metal, such as welding aluminum foil and copper foil. When the ultrasonic vibration is transmitted to the pressed multilayer metal foil, the contact interface of the material will change. Tangential vibration cleans the material surface, that is, it removes dirt and decomposes oxides, forming a clean and close contact between multiple layers of metal sheets. At this time, the electrons share the atoms on both sides of the interface and form a solid bond connection.
FAQ
Q:At present, the traditional crimping process can no longer meet the requirements of high-voltage wiring harnesses, and ultrasonic metal welding technology is required. So how to choose the type of Ultrasonic Harness Welding machine for new energy vehicles?
A:First of all, we will make a description according to the application technology and parameters of ultrasound:
A. Working frequency:
①Low power and high frequency: according to the 35KHz standard in Europe and 40KHz in the United States and China, the power capacity is basically about 1000W;
②20KHz standard operating frequency, power capacity covers 2000W-15000W;
③15KHz standard operating frequency, 15KHz can no longer be called ultrasonic actually, because of the high noise, it is only suitable
Used in some special situations, such as welding thick aluminum sheets, B. Working vibration mode:
① Torsional vibration mode
The structure of the vibration system in the torsional vibration mode is complex, so in most cases, a combination of multiple transducers is required.
②Bending vibration mode
The unique advantages of the bending vibration mode are: the work piece has a large operating range (that is, the application of special-shaped terminals is not easy to produce mechanical interference); the pressure system is efficient, and there is no warping of the welding head. The power of the welding machine in bending vibration mode can cover 2000-15000W.
③Longitudinal vibration system
The longitudinal vibration system is currently the most mainstream ultrasonic metal welding system, with the most manufacturers.
According to the structure of the welding head, the longitudinal vibration system is divided into a half-wave welding head system and a full-wave welding head system.
Half-wave system, because the lateral pressure is easy to cause the welding head to warp, it is more difficult to apply when the power output exceeds 7000W;
The full-wave welding head system is a system formed because of high power and increased pressure at two nodes, but the longitudinal full-wave system is prone to mechanical interference, which is not ideal for application convenience and is highly dangerous for manual operation.
