Generally installed in some specific object cleaning production line.
Typical soft magnetic device ultrasonic cleaning equipment: the cleaned objects can be driven from the feed port of the stainless steel mesh belt sent to the ultrasonic cleaning machine tank cleaning, and then after spraying, drying and other processes out of the material to achieve the cleaned objects can be directly packaged into the warehouse.
2, general ultrasonic cleaning machine features
General ultrasonic cleaning machine cleaning parts applicability, has been widely used in electronics, clocks and watches, optics, machinery, automotive, aviation, atomic energy industry, medical equipment and many other industries. Specialized ultrasonic cleaning machine is generally installed in some specific object cleaning production line. Typical soft magnetic device ultrasonic cleaning equipment, the cleaned objects from the inlet can be driven by the stainless steel mesh belt sent to the ultrasonic cleaning tank cleaning, and then after spraying, drying and other processes out of the material to achieve the cleaned objects can be directly packaged into the warehouse.
The structure of the ultrasonic cleaning machine generally have ultrasonic power supply and cleaner into one or separate layout of the two forms, generally low-power (200W or less) with a one-piece structure of the cleaner, while the high-power cleaner using a split structure.
Ultrasonic cleaner split structure consists of three main parts (1) cleaning cylinder; (2) ultrasonic generator; (3) ultrasonic transducer.
Cleaning cylinder: cleaning cylinder is used to load the cleaning fluid and the stainless steel container to be cleaned workpiece, most of the workpiece can be loaded in the mesh frame, and then put together with the cylinder cleaning.
Ultrasonic generator: ultrasonic cleaning machine with ultrasonic generator, from the use of the type of components can be divided into tube-type, silicon controlled and transistor-type. In recent years has developed to use high-power "power module" approach. Its output power from tens of watts until a few kilowatts, working frequency from 15kHz-40kHz.
Ultrasonic cleaning machine with ultrasonic generator, has the following characteristics:
(1) with the cleaning fluid depth is different, transducer *** vibration frequency and impedance varies greatly. But practice shows that the slot into the appropriate amount of cleaning materials, basically can be stabilized at a certain value.
(2) Generally speaking, due to the cleaning load change is small, can not require complex frequency auto-tracking circuit.
(3) practical ultrasonic generator, most of the use of high-power self-excited feedback oscillator.
Ultrasonic transducer: ultrasonic cleaning machine with the transducer.
There are mainly the following kinds:
①Magnetostrictive transducer domestic magnetostrictive transducer most of the window-type transducer stacked with nickel, it will be silver soldered at the bottom of the cleaning cylinder, and then use the wire in the window around a certain number of rolls and become. This transducer can withstand greater power, and good reliability, long service life. Disadvantages for the efficiency of piezoelectric transducer low, raw materials, nickel is expensive.
② piezoelectric transducer at home and abroad, most of the ultrasonic cleaning machine with a piezoelectric transducer. This transducer generally has two piezoelectric ceramic chip composition. A cleaning machine with more than one transducer, by the adhesive bonded to the bottom of the cleaning cylinder and by the parallel connection to form a cleaning machine transducer. Distance between the base element of the transducer (for a frequency of 20kH4 generally in 5-10mm is good, too large is prone to produce bending vibration, and vibration plate corrosion, while the radiation surface is relatively reduced. Universal ultrasonic cleaner cleaning parts applicability, has been widely used in electronics, clocks and watches, optical, mechanical, automotive, aviation, atomic energy industry, medical equipment and many other industries.
At present, there is a kind of ultrasonic vapor phase cleaning machine, it is the choice of organic solvents as a cleaning fluid, has a strong ability to dissolve dirt, used to clean semiconductor wafers and other cleanliness requirements of particularly high objects
