Ultrasonic Wire Splicing
The principle of ultrasonic welding machine is to use the energy generated by high-frequency vibration to penetrate into metal surface molecules through cold grinding and horizontal movement of the same or different metals under appropriate pressure, so as to achieve the purpose of welding.
The principle of ultrasonic welding machine is to use the energy generated by high-frequency vibration to penetrate into metal surface molecules through cold grinding and horizontal movement of the same or different metals under appropriate pressure, so as to achieve the purpose of welding. This welding principle is adopted for metal seam welding and metal sealing and cutting. The advantages of ultrasonic joint copper wire are fast welding, convenient energy saving, high strength, good conductivity and no spark; the disadvantage is that the welded metal parts shall not be too thick (generally less than or equal to 5mm), and the position of welding points shall not be too large. Otherwise, it needs to be pressurized.The Ultrasonic Wire Splicing machine not only has good performance for copper wire, but also has excellent welding penetration and mixing effect for different types or similar metals (such as copper + copper or aluminum + copper).

FAQ
Q: What are the assembly steps of the ultrasonic wire splicing machine?
1. Assembly steps: Unplug the power plug and turn off the power switch to ensure that the system is turned off;
2. Loosen the two locking screws on both sides of the sensor / amplifier / welding head assembly fixture (loosen counterclockwise and tighten clockwise);
3. If necessary, tighten the screws in the center of the sensor / Horn / welding head assembly fixture to open the fixture;
4. Loosen the two locking screws on the sensor clamp (white part) (loosen counterclockwise and tighten clockwise);
5. Insert the assembled transducer / Horn / welding head assembly into the central hole of the fixture from the back of the rack, and adjust the insertion depth of the assembly according to the installation position of the lower bottom mold. Rotate the welding head and adjust the direction of the welding head and the lower die. At this time, the two locking screws on both sides of the fixture can be tightened, and the installation of the sensor / luffing welder / welding head assembly is now complete.
The copper wire connection of ultrasonic joint is very short, and the temperature is lower than recrystallization. It is also different from the force because the additional static force is much smaller than the force. Generally, in the initial stage of ultrasonic bonding process, the oxide on the metal surface is removed by tangential vibration, while the microminiaturization and destruction of the protruding part of the rough surface increases the contact surface and the temperature of the area. The interface of workpiece is plastic forming. Under the action of contact force, they are close to the distance where atomic gravity can produce effect, that is, the forming point. Otherwise, the ultrasonic amplitude will reduce the connection strength or even damage it
