The reason why the ultrasonic welding machine does not emit waves
In the process of ultrasonic welding, there will be occasional silent waves. So, what is the reason that the ultrasonic plastic welding machine does not emit waves? No matter what problem you encounter or judge the problem, you can use the substitution search method to experiment, such as changing a mold, or even changing an ultrasonic generator, to narrow down the problem step by step. In the actual application of the ultrasonic welding machine, there is no ultrasonic output and there is no way to weld. Please don't panic. First of all, you must judge whether it is the problem of your debugging or the problem of the machine itself. Detect the no-load current, and the current is normal, which is the problem you are debugging. If the current is normal, it is necessary to judge the air pressure and welding time. For example, when the current is overloaded or the current is large, if the debugging fails, you can remove the mold to judge.
Ultrasonic welding machine silent wave self-check method:
1. The problem of artificial setting
1. Start the device and adjust the device to automatic mode;
2. Check whether the welding time is 0s, there will be no waves at 0s, and readjust the welding time;
3. Check whether the delay time is too long. If the setting time is too long, the wave will not be sent when the wave transmission time is not reached during our test. This is the need to modify the delay time to see if the wave is sent.
4. Check whether the link line of the transducer is properly connected.
Second, the problem of ultrasonic equipment
If the ultrasonic welding machine has no sound waves, the first step is to remove the mold first, and then check whether there are sound waves and whether the sound waves are normal. If there is no sound wave, check whether the current pointer is oscillating. If the pointer oscillates, check whether the vibrator wire is off. If after all the above inspections, it still fails, then it is a problem with the ultrasonic generator. For example, the ultrasonic crystal plate is broken, or the rectifier bridge is broken, the ultrasonic transducer is broken, the vibration plate is broken, and the capacitor is broken. Now, there will be this phenomenon. No sound wave can't be tuned out, and it can be repaired only by replacing the electronic components.
The maintenance of the ultrasonic welding machine is also very important when using the ultrasonic welding machine. If the maintenance is good and the maintenance is good, the frequency of failure will inevitably be less, otherwise it will affect the service life of the ultrasonic welding machine and increase the frequency of maintenance.
