Ultrasonic Multi Wire Welding by 20Khz 3000w Ultrasonic Energy Control Mode​


Description:

Ultrasonic wire harness welding uses high-frequency vibration waves to transmit to the surface of two wire harness workpieces to be welded. Under pressure, the surfaces of the two wire harness workpieces are rubbed together to form a fusion between molecular layers. The advantage is that it is fast and energy-saving. High fusion strength, good electrical conductivity, no spark, close to cold processing; the disadvantage is that the welded metal parts should not be too thick (generally less than or equal to 5mm), the solder joints should not be too large, and need to be pressurized.


Parameters:

What are the technical requirements for ultrasonic metal welding?

In general, the technical requirement is to be able to safely weld metal with ultrasonic technology. Due to the application of ultrasonic waves to welding metals, higher requirements are placed on ultrasonic welding technology; compared to ordinary plastic welding, the requirements for power capacity, stability and automation control are not the same level:

A. 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. Modest equipment uses the world's most advanced PLL phase-locked loop frequency automatic tracking technology, no need to adjust the frequency of the mold and work. Stable ultrasonic generators also require: constant amplitude function and stepless adjustment of amplitude. The constant amplitude function needs to control the real current of the transducer, which is the key to stable production; the stepless adjustment of the amplitude is the basic for ensuring the basic use of the equipment. For example, it can weld copper and weld by parameter adjustment on the same equipment. Aluminum material.

B. Ultrasonic metal requires a highly wear-resistant welding head, which requires high hardness of the welding head, and the ultrasonic itself requires good toughness of the welding head, which creates a contradiction requirement. A good welding head requires both high hardness and toughness. Qianrong equipment uses high-quality alloy steel to manufacture welding heads, and its life and manufacturing precision are comparable to those of similar products in Europe and America.

C. The transducer is a core component of the ultrasonic wave, which is equivalent to an automobile engine. The metal requires the transducer to have a large power capacity and a long-term attenuation.

D. Ultrasonic metal welding requires a high-quality control system. Generally, there are three basic control modes: welding energy, time and height. Multiple quality control software meets different needs.
