Description

technical field [0001] The present application relates to the technical field of ultrasonic products, in particular to a circuit, method, device and storage medium for displaying load characteristics of ultrasonic products. Background technique [0002] Ultrasonic products use the piezoelectric effect of piezoelectric ceramics to convert high-frequency AC electrical energy into mechanical energy, and drive the load to make ultrasonic vibrations, so as to be used in ultrasonic processing, ultrasonic welding and other fields. In the related art, since the piezoelectric effect characteristics of ultrasonic products are quite complex, as the voltage frequency applied to both ends of the piezoelectric ceramics is different, the piezoelectric ceramics will change inductively and capacitively. Shape size, degree of annealing, assembly pressure, load pressure, and surface quality are all strongly correlated. Ultrasonic products are often complex in structure and changeable in chara...

AI Technical Summary

Problems solved by technology

Ultrasonic products often have complex structures and changeable characteristics. Different types and different batches of product characteristics vary widely. Even products produced in the same batch will have deviations in characteristics due to various problems in the production process.

[0003] The characteristics of ultrasonic products can be detected by a professional impedance analyzer during the production process. However, in actual use, especially when the product is installed and debugged, there is no professional testing equipment, and the installation can only be carried out by observing the actual processing effect. and debug

The installer needs to adjust the state of the ultrasonic product and the state of the machine equipment at the same time. To achieve a better load processing effect, they can only adjust with the help of debugging experience and repeated attempts to the effect of the equipment. This kind of debugging is often Complicated and inefficient, such as improper installation pressure, improper selection of parameters, product looseness, product vibration cracking and other details are not handled well, and it is difficult to find the problem during the debugging process, resulting in the product not working properly
