Automobile Wiring Harnesses 20Khz Ultrasonic Metal Welding Device
Description:
Ultrasonic harness welding is the generation of ultrasonic
oscillating electrical energy by an ultrasonic generator of several
tens of kilohertz, and the mechanical vibration of the ultrasonic
frequency is generated by a magnetostrictive transducer. The
pressure-welded trowel is placed in the appropriate position at the
end, and the boring tool must simultaneously produce a mechanical
vibration called alternating shear stress. The oxide film on the
surface of the aluminum wire and the aluminum pad of the chip is
damaged. At the same time, due to the friction, a certain amount of
heat is generated at the interface to cause a certain plastic
deformation of the aluminum wire on the solder and the aluminum pad
on the chip, so that the aluminum atom metal bond Close contact to
form a strong bond.
The vibration of anything will make a sound, and any sound will
happen by vibration. The human ear can only perceive a certain
range of sounds, up to 18000 (18K) Hz. The higher frequency sound
we call it ultrasound. Ultrasonic waves produce high-frequency
vibrations that allow us to easily weld non-ferrous metals.
Ultrasonic wire harness welding machine is a derivative device of
ultrasonic metal welding machine. It is mainly used for the welding
of copper wires and aluminum wires for welding of automobile wiring
harnesses and motorcycle wiring harnesses. Therefore, it is often
called the automobile wire harness welding machine.

Precautions of Automotive wiring harness ultrasonic welding :
Ultrasonic welding of automobile wire harnesses is to weld a
multi-strand or single-strand wire into a wire knot by ultrasonic
action. The advantage is that the conductivity after soldering is
good, the resistivity is extremely low or close to zero; the
soldering time is short, and no flux, gas or solder is needed.
Automotive wire harness ultrasonic welding should pay attention to:
1. It is best not to tin or galvanize the wire, although it can be
welded in some cases, but the effect will be bad.
2. Select the model according to the cross-sectional area of the
wire.
3. Wire harness welders require good quality control software to
make quality judgments for each solder joint.
4. Control mode adopts energy control mode
Advantages:
1) The welding material does not melt and is not fragile.
2), good electrical conductivity after welding, the resistance
coefficient is extremely low or nearly zero.
3), the welding metal surface requirements are low, oxidation or
plating can be welded.
4), welding time is short, no need for any flux, gas, solder.
5), welding without sparks, environmental protection and safety.
