Copper And Aluminum Conversion Ultrasonic Wire Harness Welding Machine By Ultrasonic Metal Technology

Copper and Aluminum Conversion Welding by 20Khz Ultrasonic Metal Technology

Description:

Ultrasonic copper alloy wire harness welding machine is to use the principle of ultrasonic friction to achieve surface welding of different media, which is a physical change process. First, the leading end of the wire must be processed to form a spherical shape, and the welded metal surface is first pre-heat treated; then the gold ball is combined with time and pressure to produce a sag deformation on the metal welding surface, so that the two media A reliable contact is achieved, and by ultrasonic vibration, a metal bond is formed between the two metal atoms under the action of atomic affinity, thereby realizing the welding of the gold wire lead. Gold wire ball bonding is superior to silicon-aluminum wire soldering in electrical and environmental applications, but the application range is relatively narrow due to the necessity of heating the weldment with precious metals. The welding time is short, the welding is not overheated or the welding penetration is not enough. The copper wire welding equipment does not need any flux, protective gas, and the welded joint is an alloy layer which is melted into one body. The chemical properties are stable and the conductivity is good. The resistance system and the material are original. The coefficients are basically the same. No splash, bright solder joints, no copper plating, no cracking at the terminals.


Parameters:

What is the difference between an ultrasonic metal welding machine and an ultrasonic plastic welding machine?

First of all, 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 basically meet the requirements.
Secondly, due to the application of metal welding machines to welding metals, higher requirements are placed on 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.
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.
