Ultrasound cleaner is an instrument used to remove pollutants. It converts the sound energy of power ultrasonic frequency source into mechanical vibration through transducer to clean articles. It is widely used in industry, national defense, biomedicine and so on.
It has been proved that when ultrasound acts on liquid, the breakdown of each bubble in liquid will produce a shock wave of great energy, which is equivalent to the instantaneous high temperature of several hundred Baidu and up to thousands of atmospheric pressure. This phenomenon is called "cavitation effect". The ultrasonic cleaning is achieved by the shock wave produced by the breakdown of bubble in liquid. The function of cleaning and scouring the inner and outer surface of the workpiece. Ultrasound propagates in the liquid, making the liquid and the cleaning tank vibrate together under the ultrasonic frequency. When the liquid and the cleaning tank vibrate, they have their own natural frequency. This vibration frequency is the acoustic frequency, so people hear buzz.
The ultrasonic cleaner is to remove liquid and solid contaminants on the working surface, so as to achieve a certain degree of cleanliness. Cleaning is a very complex physical and chemical process.
Cleaning is not only related to the nature, type, form and adhesion degree of pollutants, but also to the physical and chemical properties of cleaning media, cleaning performance, material quality and surface state of workpiece. The ultrasonic cleaner is a scientific and reasonable cleaning process according to the cleaning conditions.
constitute
The whole process of the automatic ultrasonic cleaning machine is mechanically automatic. (A single-beam multi-arm manipulator is used). The automatic ultrasonic cleaning machine is mainly composed of two parts: the ultrasonic cleaning tank and the ultrasonic generator. The ultrasonic cleaning tank is made of high-quality stainless steel with strong elasticity and corrosion resistance, and the bottom is equipped with an ultrasonic transducer oscillator; the ultrasonic generator generates high frequency and high pressure, which is transmitted to the transducer through a cable connection line, and the transducer generates high frequency resonance with the vibration plate, so that the solvent in the cleaning tank is contaminated by the ultrasonic action. Clean the dirt.
Application scope
Among all the cleaning methods, multi-hook synchronous automatic ultrasonic cleaning is one of the most efficient and effective. The reason why ultrasonic cleaning can achieve such effect is closely related to its unique working principle and cleaning method. We know that in production and life, there are many things to be cleaned, and there are many kinds and links to be cleaned. For example, the removal of pollutants from objects, the dredging of small holes, the common manual cleaning methods can not meet the requirements of abnormal objects and hidden places of objects, even steam cleaning and high-pressure water jet cleaning. Ultrasound cleaning can also kill bacteria, dissolve organic pollutants, prevent over-corrosion and so on. Therefore, ultrasonic cleaning is increasingly widely used in all walks of life: (1) machinery industry: anti-rust grease removal; measuring tool cleaning; oil removal and rust removal of mechanical parts; Cleaning of carburetor and automobile parts, dredging and cleaning of filters and filters, etc. (2) Surface treatment industry: degreasing and rust removal before electroplating; cleaning before ion plating; phosphating treatment; removal of coke deposits; removal of oxide scales; removal of polishing paste; surface activation treatment of metal workpieces, etc. (3) Instrument industry: cleaning of precision parts before assembly with high cleanliness. (4) Electronics industry: Printed circuit boards except rosin, weld spots; high-voltage contacts and other mechanical and electronic parts cleaning. (5) Medical industry: cleaning, disinfection, sterilization of medical instruments, cleaning of experimental utensils, etc. Semiconductor industry: high cleanliness cleaning of semiconductor wafers. _Clock and watch head, jewelry industry: remove sludge, dust, oxide layer, polishing paste, etc. Chemical and biological industries: cleaning and descaling of experimental utensils. Optical industry: optical device degreasing, sweating, ash removal, etc.
