50mm Diameters Ceramics Long Column Ultrasonic Welding Transducer

Description:

Ultrasonic welding machine transducer: A: magnetostrictive effect, B: inverse effect of piezoelectric effect. The magnetostrictive effect is more commonly used in early ultrasonic applications. The advantage is that the power capacity can be made large; the disadvantage is that the conversion power is low, the production is difficult, and it is difficult to mass-produce industrial production. Since the invention of piezoelectric ceramic transducers, the application of piezoelectric effect counter effects has been widely used.

What are the common problems with ultrasonic transducers?

1. The ultrasonic vibrator is damp. The plug connected to the transducer can be inspected with a megohmmeter. The 2 pin is the positive pole of the ultrasonic transducer, and the 3 pin is the negative pole of the transducer and The outer casing of the transducer is connected. Check the insulation resistance value between 2 and 3 feet to judge the basic situation. Generally, the insulation resistance is required to be greater than 30 megohms. If the insulation resistance value is not reached, the transducer is generally damp. The whole transducer (excluding the sprayed plastic case) can be placed in the oven for about 3 hours at 100 °C or used to remove moisture to the resistance value. Normal until now.

The transducer vibrator is fired and the ceramic material is broken. It can be combined with the naked eye and the megohmmeter. Generally, as an emergency treatment measure, the individual damaged vibrator can be disconnected without affecting the normal use of other vibrators.

2. The vibrator is degummed. Our transducer is made of cement and screw fastening. Under normal circumstances, this kind of situation will not occur. Due to the action of the screw, the vibrator will not fall off the vibrating surface after degumming. The general judgment method It is to gently shake the tail of the vibrator by hand and carefully observe the glue on the vibrating surface to make a judgment. Generally, the power output of the ultrasonic power supply is normal after the demagnetization occurs, but since the vibrator is not well connected to the vibration surface, the vibration effect of the vibration surface is not good, and the vibrator may be burnt after a long time. The treatment method of vibrator degumming is rather cumbersome, and the general situation can only be returned to the manufacturer for solution. The most effective way to avoid degumming of the vibrator is to take care not to hit the vibrating surface during normal use.

3. Perforation of the vibrating surface, generally the vibrating surface perforation may occur after the transducer is fully loaded. This is due to the high-frequency vibration fatigue of the vibrating surface of the stainless steel plate for a long time. The perforation of the vibrating surface indicates that the service life of the transducer has been When it arrives, it can only be replaced.
