Providing 20Khz Ultrasonic Splicing Metal Welding Solution for Tin
and Oxidized Wire Harnesses
Description:
Ultrasonic automotive wire harness welding uses ultrasonic metal
welding technology to weld metal wire harnesses, and converts
high-frequency electrical energy into a mechanical vibration energy
through a transducer to act on the metal wire harness. When the
temperature of vibration friction heat reaches the melting point of
the wire metal, the wire harness It will melt, and the wire harness
will apply a certain pressure while the wire bundle is being fused.
Finally, the wire harness welding device moves away and stops the
mechanical vibration, which will form a wire harness welding
effect. During the wire harness welding process, no current is
passed through the weldment, and no welding arc is generated.
Because ultrasonic welding does not have problems such as heat
conduction and electrical resistivity, it is undoubtedly a kind of
welding for non-ferrous metal wire harnesses. In an ideal metal
wire harness welding system, the wire harness welding effect is
generally square.
Features:
1. High-quality welding head: Metal welding, as an industrial use,
necessarily requires a high-life welding head.
2. High-quality control system: It has three basic control modes:
welding energy, time and height. Various quality control softwares
meet different needs.
3. Metal welding machines use high-quality transducers: such as
20kHz transducers, they must be able to withstand loads of more
than 3kw for a long time. Many companies' transducers, which use
ordinary plastic welded transducers, are difficult to distinguish
in appearance, which is irresponsible.

What are the differences between ultrasonic metal welding machines
and ultrasonic plastic welding machines?
1. The way of working is different. Generally, the vibration
direction of the welding head in the ultrasonic plastic welding is
perpendicular to the welding position, and the vibration direction
of the welding head in the ultrasonic metal welding machine is
parallel to the welding position. In some special cases, plastic
welding can also be used in parallel directions, such as thin
plastic parts.
High power capacity, stable ultrasonic generator:
The first requirement for a stable ultrasonic generator is:
automatic frequency tracking. Automatic frequency tracking ensures
that the transducer system can operate in a resonant state, ie the
maximum amplitude of the weld head. The frequency is automatically
tracked, the mold is replaced and the frequency is not required to
work, which is the basic requirement for metal welding. Equipment
with adjustable inductance and manual frequency adjustment can not
meet the requirements.
2. Due to the application of metal welding machine to welding
metal, higher requirements are put forward for ultrasonic welding
technology. Compared with ordinary plastic welding, the
requirements for power capacity, power density, stability and
automation control are not the same. level. At present, domestic
ultrasonic plastic welding generators basically adopt self-excited
circuits, which are typically represented by full-bridge circuits
and half-bridge circuits commonly used in Taiwanese machines. The
remarkable feature is that there is a tuning inductor. If the
existing mature technology for plastic welding is directly
transferred to metal welding, its technical insufficiency will lead
to unstable use of the product; its only advantage is that it is
cheap, but for the high requirements of metal welding itself, This
advantage is very pale.
Stable ultrasonic generators also require: constant amplitude
function and stepless adjustment of amplitude. Constant amplitude
function, which can ensure the consistency of welding, is the key
to stable production; the stepless adjustment of amplitude is the
basic to ensure the use of equipment, for example, it can weld
copper and weld aluminum materials through parameter adjustment on
the same equipment.
High power capacity: Compared with plastic welding machines, metal
welding machines require high energy density, and must have
relatively high power capacity. For example, a 20 kHz machine
basically requires a power capacity of more than 3000 W. Many
companies often have false nominals for power capacity, so we only
need to compare them with the plastic welders they make, because
the plastic welder is too high to be unbelievable.
