On the baby diaper production line, ultrasonic welding machines are undoubtedly the "efficiency responsibility". It quickly fuses the diaper surface with the absorbent core through high-frequency vibration, achieving seamless sealing without the need for glue, which is both environmentally friendly and efficient. Compared to traditional hot melt technology, ultrasonic welding speed is several times faster.
However, when the equipment experiences "frequency tracking failure", the welding points may experience virtual welding, burning, or even equipment shutdown, directly causing the production line to lose hundreds of products per hour. This article will start from the working principle of the equipment, deeply analyze the root cause of frequency tracking failure of a single source ultrasonic welding machine, and provide a practical solution.
The deep cause of frequency tracking failure is that the frequency tracking function of ultrasonic welding machine is like the "automatic tuner" of the equipment, which monitors the vibration frequency of the transducer in real time and automatically adjusts it to ensure that the welding energy is always in the best state. The common causes of failure can be classified into four categories:
1. Equipment aging: Long term high load operation can cause performance degradation of piezoelectric ceramic chips, or welding mold wear can cause resonance frequency shift;
2. Parameter mismatch: Human error in setting welding time, pressure, or amplitude, exceeding the adaptive adjustment range of the equipment;
3. Environmental interference: Excessive humidity in the workshop can lead to a decrease in insulation of electrical components, or fluctuations in power supply voltage can affect control circuits;
4. Component failure: hardware issues such as damage to the generator power module, poor contact of sensor circuits, etc.
APSonic Ultrasonic Standardized Maintenance Process
1. Online consultation for pre diagnosis: Customers can describe the fault phenomenon of a primary ultrasonic welding machine through phone or video, and engineers will preliminarily identify the scope of the fault based on experience.
2. On site deep inspection technicians carry professional instruments and on-site inspection equipment to accurately locate faulty modules.
After developing a maintenance plan to identify the fault point, the engineer will provide transparent maintenance suggestions.
4. Conduct no-load testing, simulated welding, and continuous operation testing on the ultrasonic welding machine after debugging, verification, and maintenance to ensure the normal operation of the equipment.
I hope the introduction in this article can help you better solve the problem of frequency tracking failure in a single source ultrasonic welding machine, and enable the equipment to quickly return to its optimal state.
