Ultrasonic Tab Welding Machine
Ultrasonic metal spot welding machine for lithium ion batteries is a special device used in the manufacturing process to perform spot welding. It uses ultrasonic technology to weld two metal sheets together, forming the electrodes of the battery.
Ultrasonic spot metal welding machine is an advanced high-tech equipment that converts high-frequency electric energy into a mechanical vibration energy through a transducer and acts on the bases material, to generate high-frequency friction between the surfaces of the two work-pieces until the surfaces of the two bases material are heated and welded together. It can perform spot-like and strip-shaped soldering on thin materials such as copper, silver, chrome, nickel and other conductive metals. It can be widely used in lead wire of silicon controlled chip leads, fast-fuse holders, electrical lead terminals, lithium ion, nickel point-like, strip-shaped soldering of poles such as hydrogen and nickel-cadmium batteries. The welding process of an ultrasonic spot welder is a mechanical process in which no current flows through the material and no melting occurs. Moreover, the same or the different alloy materials can achieve the ideal welding, the electrical and the thermal properties are not achieved by other processes. Compared with fusion welding, ultrasonic welding has low electrical consumption, long life.
Main components
Controller, ultrasonic horn, transducer, welding head, pneumatic mechanism and fixture.
1. Mode (With automatic, mode adjustment two modes) : Adjust the automatic mode when working, and adjust the mode when changing the mold.
2. Current : The actual current amount per work, reflecting the power of the machine, this item is not adjustable.
3. Frequency : The frequency of automatic tracking of the machine at each work ensures the stability of the machine. This item cannot adjust.
4. Yield : Counting effect, the number is increased by 1 for each work
5. Sweep Frequency : For the frequency calibration between the generator and the welding head, the vibrator, press the sweep button when replacing the welding head, the generator will automatically match with the vibrator and the frequency of the welding head
6. Mold Adjustment For mold replacement
7. Automatic : Press automatic when welding the material, the machine starts running
8. Delay : It refers to the time between the welding head descending to the sound wave, during which the sound generator does not emit ultrasound. This project can be adjusted according to the actual welding material.
9. Welding : The generator emits the sonic time; this item can be adjusted according to the actual work.
10. Cooling : The time when the welding head stays on the welding material after the completion of acoustic wave, this item can be adjusted.
11. Vibration Drop : The generator's secondary sounding time, to prevent the welding material from sticking to the welding head, this item can be adjusted according to the actual work.
12. Amplitude : Adjust the power of the machine, this project can be adjusted according to the actual work settings
13. Reset : Remove overload by reset when machine overloads. Light touch reset button to trigger alarm.
14. Zero (Clear capacity count) : Clear capacity by touching the zero-clearing button
15. Sonic test : Test whether the sounder is pronounced, current, frequency is normal. Touch the sound wave test button to test the sound wave
