Ultrasonic Battery Pack Welder
Working principle of ultrasonic battery pack welder uses ultrasonic metal welding technology to weld the metal wire harness, and converts high-frequency electric energy into mechanical vibration energy through the transducer to act on the metal wire harness.
The Ultrasonic Battery Pack Welder is composed of two parts: a machine and an ultrasonic power generator.
-
The machine is composed of a chassis, a guide post, a transducer, a pneumatic system, a PC circuit, and a bottom mold.
-
Acoustic component：The acoustic component is composed of transducer and welding head. The transducer adopts piezoelectric vibrator, whose function is to convert electrical energy into mechanical vibration. The converter is analogous to the transformer in the circuit, which plays the role of mechanical damping conversion and amplitude amplification. The welding head is designed according to the welding requirements and the shape of the weldment. It also plays a role of secondary impedance transformation and amplitude amplification. In terms of structure and shape, the welding head is not complicated, but it needs the best design, the best materials and good processing technology. Welding heads with complex shapes and large sizes are difficult to design, and they are generally designed by manufacturers.
-
Air pressure system： The air pressure system is powered by compressed air, through the solenoid valve switching circuit, pushing the cylinder piston to drive the welding head to move up and down. The pressure regulating valve is used to control the air pressure, and the one-way throttle valve is used to control the lifting speed.

FAQ
Q: Why do you choose a Ultrasonic Battery Pack Welder?
A:1, high reliability: The machine ensures excellent process control through time, energy, power and upper limit monitoring.
2, cost saving: It avoids consumables such as solder, flux, bending materials and brass materials, making ultrasonic welding the most cost-effective process.
3, low energy consumption: the energy required by ultrasonic welding is less than 1/3 of resistance welding, without preheating.
4, tool life: ultrasonic tools are processed by high-quality tool steel, with excellent wear resistance, easy installation, high welding accuracy.
5, high efficiency and automation: typical welding speed is not more than 0.5 seconds, small size, less maintenance workload, strong adaptability, so that ultrasonic equipment becomes the first choice for automatic assembly line.
6, low working temperature: because ultrasonic welding does not produce a lot of heat, so it will not make the metal workpiece annealing, will not make the plastic shell melting, also do not need cooling water.
7, in addition to insulation: in most cases, the high-frequency friction of ultrasonic welding makes people do not need to peel the insulation skin of enamelled wire or clean the workpiece surface in advance.
