Ultrasonic cleaning machine technology has a history of more than 30 years, and Japan began to use it 25 years ago, but a misunderstanding has been puzzling this technology, which makes people doubt the effect of ultrasonic cleaning machine. According to the traditional theory of ultrasonic cleaning machine, bubbles play a cleaning role. After repeated experiments, Yoshinoya chaiye found that bubbles are just simple gas bursts caused by strong thick and dense waves of ultrasonic waves, which will inhibit or even eliminate the cleaning power of ultrasonic cleaning machines. What really plays a cleaning role is vacuum cavitation. This discovery has achieved a revolutionary breakthrough in the field of ultrasonic cleaning machines. 1987, Yoshinoya chaiye published the Basic Theory of Ultrasonic Cleaning Machine. In order to be different from the traditional theory, he called his research achievement "chaiye Theory", and the ultrasonic cleaning technology based on it was defined as a new ultrasonic cleaning technology. According to this theory, the ultrasonic cleaning machine he developed has a much better cleaning effect than similar products, and can successfully control the position, density, efficiency and impact of cavitation. Other manufacturers in the same industry still can't clean and remove the welding burr well after 25 minutes, but they can remove it with Pleiades cleaning equipment for 6 seconds. The flux-dense parts that can't be removed by other manufacturers' equipment in 2 hours can be removed by the Pleiades cluster in 2 minutes, and the processed objects can be guaranteed not to be damaged.
The Birth of "Pleiades" Speaking of the research and development process of ultrasonic cleaning machine, Yoshinoya chaiye was particularly excited. 1970, Yoshinoya graduated from Fukushima Institute of Technology, Japan, majoring in electrical engineering, and worked in Shemu Sewing Machine Industrial Technology Research Institute. 1975 entered an industrial cleaning company. At that time, there was just an ultrasonic cleaning machine, but a large number of toxic and harmful chemical solvents such as trichloroethylene and freon were used as cleaning media, which caused serious environmental pollution. At that time, Japanese industry was in a period of rapid development, and a large amount of industrial wastewater was discharged into rivers. Many people get sick because of drinking polluted water, especially some disabled people die prematurely because they are forced to engage in toxic and harmful work. Seeing all this, Yoshinoya chaiye's strong sense of social responsibility made him determined to use environmental protection technology to benefit mankind. He said, "The world has nurtured me, and I have an obligation to contribute to the world!" " From then on, he embarked on the road of studying environmental protection ultrasonic cleaning machine.
An accidental factor prompted him to discover the secret of ultrasonic cleaning machine. At that time, due to lack of funds, everything could only be simplified from scratch, not to mention the experimental equipment. Because most ultrasonic cleaning tanks are made of stainless steel, it is impossible to observe the ultrasonic waves in the medium from the side. Because of the lack of money, Shibano Jiaying bought a transparent plastic fish tank instead, so it is easy to observe the change of the cleaning tank. He found that many bubbles generated by the ultrasonic generator placed at the bottom of the fish tank kept rising, and one big bubble turned into two small bubbles and finally exploded. The traditional principle of ultrasonic cleaning machine is to generate bubbles through the propagation of ultrasonic waves in liquid medium, and then clean the surface of the object through the force generated by bubble explosion. However, the cleaning effect is not ideal because there is air in the bubbles and the force generated by the explosion is limited. After repeated experiments and continuous improvement, Yoshinoya chaiye finally developed a new type of ultrasonic cleaning machine, which turned bubbles into real cavities, thus correcting people's misunderstanding of ultrasonic cleaning machine technology for a long time. He also tried to use water to replace toxic and harmful media such as freon, which was commonly used in ultrasonic cleaning machines before, and took a step towards the goal of environmental protection. In 1993, this invention won the "Environmental Protection Award for Ozone Layer Protection of the United States Environmental Protection Agency (EPA)". The digital measuring instrument of cleaning force invented by him can measure the sound pressure and cavitation impact of ultrasonic wave at any time, so as to adjust the cleaning device to the best state.
Ultrasonic cleaning machine technology has a long history, which proves its reliability and good development prospect.
