Principle of Ultrasonic Welding Technology

Kable-X is a high-end customized Wiring Harness manufacturer. The company has advanced Wire Harness production equipment and testing equipment. Have the ability and confidence to provide customers with products of good quality and excellent price. Our Medical Cable Assembly, Industrial Cable Assembly, communication wire harness and new energy wiring harness have been well received by customers. The factory introduced ultrasonic welding technology, and used this technology to produce and process automotive wiring harnesses. Next, let's learn about the principle of ultrasonic welding technology.
1. The ultrasonic generator amplifies the electrical energy into a 20KHz high-voltage power supply through internal rectification, voltage transformation, and special power tube, and then designs a low-resistance wire to output it to the piezoelectric ceramic transducer.
2. The piezoelectric ceramic in the piezoelectric transducer generates radial vibration under the electrode of the high-voltage power supply, and the vibration is transmitted to the working surface of the transducer through the upper and lower metal cover plates. The cover plate of the transducer can be amplified according to the work needs. shape, to initially amplify the vibration amplitude of the ceramic.
3. The vibration of the transducer is transmitted to the special coupler, and the moving rod of the coupler is pulled to make lateral vibration.
4. The welding head is installed on the lateral vibration end. When ultrasonic is applied, pressure is applied downward to the coupler in the vertical direction of the vibration rod, and the pressure direction and the ultrasonic vibration direction are perpendicular to each other, so as to achieve the effect of friction welding.
