1. Specialized ultrasonic cleaning machines are generally installed on production lines for cleaning certain specific objects. Introduction to typical ultrasonic cleaning equipment for soft magnetic devices: The objects to be cleaned are sent into the ultrasonic cleaning tank through a stainless steel special mesh belt that can be driven from the feed port for cleaning. After going through processes such as spraying and drying, they are discharged, allowing the cleaned objects to be directly packaged and stored in the warehouse.
Brief descriptions of each process are as follows:
1. Feeding: Semi-automatic feeding can be adopted for object feeding.
2. Piezoelectric transducer: Currently, most ultrasonic cleaning machines at home and abroad use piezoelectric transducers, which have an L-shaped structure. This type of transducer is generally composed of two piezoelectric ceramic wafers. A cleaning machine uses multiple transducers, which are bonded to the bottom of the cleaning tank with adhesive and connected in parallel to form the transducers of a cleaning machine. 2. General Ultrasonic Cleaning Machines: The structure of ultrasonic cleaning machines generally comes in two forms: the ultrasonic power supply and the cleaning device are integrated or arranged separately. Generally, low-power cleaning machines use an integrated structure, while high-power cleaning machines adopt a split structure. The split structure of the ultrasonic cleaning machine consists of three main parts: the cleaning tank. Ultrasonic generator Ultrasonic transducer. Cleaning tank: The cleaning tank is a stainless steel container used to hold the cleaning solution and the workpieces to be cleaned. Most workpieces can be first placed in a mesh frame and then put into the tank together for cleaning. Ultrasonic generator: The ultrasonic generator used in ultrasonic cleaning machines can be classified into electron tube type, thyristor type and transistor type based on the types of components used. In recent years, it has developed to the point where high power is used. "Power module" In this way. Its output power ranges from tens of watts to several kilowatts, and the operating frequency is from 15kHz to 40kHz. The ultrasonic generator used in ultrasonic cleaning machines has the following features: 1. The resonant frequency and impedance of the transducer vary greatly with the depth of the cleaning solution. However, practice shows that after putting an appropriate amount of cleaning materials into the tank, it can basically stabilize at a certain value. Generally speaking, since the load variation during cleaning is relatively small, there is no need to require a complex automatic frequency tracking circuit. 3. Practical ultrasonic generators mostly adopt high-power self-excited feedback oscillators. Ultrasonic transducer: A transducer used in ultrasonic cleaning machines. The universal ultrasonic cleaning machine has strong applicability in cleaning parts and has been widely used in many industries such as electronics, watches, optics, machinery, automobiles, aviation, atomic energy industry, and medical devices.
