1, general ultrasonic cleaner
Ultrasonic cleaner structure generally have ultrasonic power supply and cleaner into one or separate layout of the two forms, the general small power (200W or less) cleaner with
integrated structure, while the high-power cleaner using a split structure.
Split ultrasonic cleaning machine structure consists of three main parts (1) cleaning cylinder; (2) ultrasonic generator; (3) ultrasonic transducer.
Ultrasonic cleaning machine with ultrasonic generator, has the following characteristics:
(1) with the depth of the cleaning fluid is different, the 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.
2, specialized ultrasonic cleaner
Generally installed in some specific objects cleaning production line.
Typical soft magnetic device ultrasonic
wave cleaning equipment: the cleaned objects from the feed port can be driven by the stainless steel mesh belt sent to the ultrasonic cleaning tank cleaning, and then
by the spraying, drying and other processes out of the material to realize that the cleaned objects can be directly packaged into the warehouse.
A brief description of the process is as follows:
①Feeding: the object feed can be semi-automatic feeding
② Piezoelectric transducer: most of the domestic and foreign ultrasonic cleaner with a piezoelectric transducer, the survey of the L-shaped structure. This transducer generally has two piezoelectric ceramic chip composition. A cleaning machine with more than one transducer, by adhesive bonding at the bottom of the cleaning cylinder and by parallel connection to form a cleaning machine transducer. Distance between the base element of the transducer (for frequency 20kH4 generally in the 5-10mm is good, too large is prone to produce bending vibration, and vibration plate corrosion, while the radiation surface is relatively reduced.
General 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. Specialized ultrasonic cleaning machine is generally installed in some specific object cleaning production line. Typical soft magnetic device ultrasonic cleaning equipment, and then after spraying, drying and other processes out of the material, the realization of the cleaned objects can be directly packaged into the warehouse.
There is also an ultrasonic vapor phase cleaner, it is the choice of organic solvents as cleaning fluid, has a strong ability to dissolve dirt, used to clean semiconductor wafers and other cleanliness requirements of particularly high objects.
