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.
