Short Description

Ultrasonic vertical tinning machine is mainly used for tinning enameled wires and welding materials that are difficult to weld by conventional methods. Compared with traditional welding methods, ultrasonic dip soldering is more environmentally friendly and energy-saving. The ultrasonic vibration and cavitation phenomenon during the dip soldering process are easy to remove the oxide layer on the surface of the weldment. At the same time, the high-frequency vibration energy will not melt the solder, which helps the solder to wet the weldment. Because it does not require flux, it saves time and cost for cleaning residual flux, while reducing corrosion to enhance the durability of the welded joint. It provides an environmentally friendly welding solution that does not use flux, avoids various problems of conventional flux welding, and provides stable and reliable welding.

Ultrasonic metal melt processing equipment is mainly used in the metallurgical industry. Under ultrasonic vibration conditions, it is more conducive to the degassing, impurity removal, grain refinement, and enhanced leaching process of metal melt. At the same time, it is also possible to achieve the composite of fibers and metals in a very short period of time, and prepare high-performance composite materials.

Principle

During the ultrasonic immersion welding process, the heat generated by a separate energy source is used to melt the filler metal, and then ultrasonic vibration energy is added. The melted solder material is used as the transmission medium for ultrasonic vibration. When high-frequency vibration energy is applied to melt welding, ultrasonic cavitation is generated on the surface of the welding tool to decompose and disperse surface oxides. The microbubbles of the air bubble rupture, cleaning the surface of the welded part to allow the moist solder to bond with pure metal. Vibration also ensures that there are no gaps in the solder joints, and the vibration energy forces the liquid solder to enter the cracks and micropores in the substrate. It helps to seal the parts and increase the surface area where solder can bond. Ultrasonic vibration can also extrude bubbles from liquid solder, making the joint suitable for high vacuum environments that require airtight sealing.

Advantages

◆ Green and environmentally friendly soldering solution

1. Will not emit any harmful chemicals to the environment and human health: No need for soldering flux or soldering flux cleaning process.

2. There is no water pollution or air pollution: no soldering flux is used during soldering, no harmful gas emissions are generated, and no industrial wastewater is produced.

◆ Achieve perfect soldering

If flux is used during soldering, tiny bubbles will be generated inside the solder, which can lead to quality problems such as cracks over time. However, ultrasonic soldering, without using flux, can penetrate very small gaps due to vibration energy, preventing tiny bubbles from being generated inside the solder and achieving perfect soldering (sealing).

2. Helpless soldering flux ->No welding joint defects caused by strong corrosion of soldering flux.

3. By using ultrasonic vibration to allow solder to penetrate small gaps, the welded joint is firm and reliable.

◆ Save production costs and improve production efficiency

Using aluminum wire instead of expensive copper wire can greatly save costs (saving 80%).

2. By not using soldering flux for welding, there is no need for pre-treatment or processes related to soldering flux, which can save equipment and production costs, simplify the soldering process, and improve production efficiency.

◆ Support the development of new materials and products

1. It can successfully weld materials that are difficult to weld, such as glass, ceramics, aluminum, and non-metallic materials that cannot be welded by traditional welding methods, which is helpful for the development of new materials.

2. Suitable for solar cell glass, semiconductor, and ceramic heaters, easy to weld for dual materials (aluminum copper, copper glass, aluminum glass, aluminum ceramic), and helpful for the development of new products.
