Ultrasonic Metal Soldering Equipment For Lithium Battery

Ultrasonic Metal Soldering Equipment For Lithium Battery

Ultrasonic metal welding is to use tens of thousands of high-frequency vibration waves per second to transfer to the surface of two metal workpieces to be welded, and then apply the necessary pressure, so that the metal surface friction and the formation of fusion between molecular layers, to achieve the purpose of welding. ultrasonic metal soldering is fast, energy-saving, high welding strength ,has good electrical conductivity, has no spark, and is close to cold processing.

In lithium battery technology, there are three metal welding methods involved: copper/aluminum foil to TAB, TAB to TAB, and TAB to bus. Because the metal welding ends are made of metals of different thicknesses and materials, one end (TAB) is relatively thick (e.g. 0.2mm) and the other end is made up of several layers of extremely thin metal sheets, which is difficult. Compared with resistance spot welding and laser beam welding, ultrasonic metal welding is a more ideal connection process for lithium-ion battery applications. The Resistance spot welding relies on the resistance of the material to generate heat for the connection. However, aluminum foil and copper foil commonly used in the battery industry have extremely low resistance, and the tough oxide layer formed on the aluminum foil surface inhibits resistance spot welding applications. Laser beam welding is very sensitive to the gap between layers of material at both ends of the weld, whereas ultrasonic metal welding processes do not have these problems. Dongho ultrasonic welding machine unique actuator can make the ultrasonic energy-efficient transfer to the welding head, welding quality is guaranteed, the ultrasonic metal welding machine is easy to operate, built-in electronic protection circuit, safe to use, can be used for the same or different metal material welding. The temperature effect of the material can be reduced to a minimum (the temperature of the welding zone does not exceed 50% of the absolute melting temperature of the metal being welded), so that the metal structure does not change, so it is suitable for welding applications in the electronic field.

Application:

New energy vehicle industry. The pole lug welding on the lithium battery pack of electric cars is popular now, as well as the welding of wiring harness and wiring harness inside the car, and the welding of wiring harness and terminal.
The medical profession. The most typical application is pin welding on integrated circuits in medical equipment. The process does not require glue or adhesives, just the bonding of the body material. Such as pacemakers used to treat patients and sensors implanted in the body. In addition, ultrasonic welding is widely used in the manufacture of intravenous catheters, blood/gas filters, dialysis machines, valves, and filters.
Electronics and computer industry. Used in chips, motors, capacitors, flash memory, microprocessors, transformers and other products. The welding process combines thin metal, usually aluminum or copper, with thick material to seamlessly connect wires and circuits. It can effortlessly connect circuits on a circuit board, making it ideal for the smartphone and computer industries.
Space industry. When making engine parts, non-ferrous metal materials such as aluminum are welded to steel. After welding, the components have high drawing strength, precise size, and a beautiful appearance. It can also meet the requirements of sealing performance and impact resistance of a closed chamber after welding.
Refrigeration industry. Copper pipes have been used as refrigeration and air-conditioning cooling system components. Because copper was expensive, aluminum tubes were used instead. However, regardless of whether copper or aluminum tubes are used, ultrasound can be used for sheet welding or sealing.
