Comprehensive analysis of vacuum low temperature plasma cleaning equipment to improve the treatment effect

Comprehensive analysis of vacuum low temperature plasma cleaning equipment to improve the treatment effect:
In recent years, with the continuous development of science and technology, the application of plasma surface treatment machine cleaning equipment has become more and more extensive. It can be used for surface activation and modification of materials, improving adhesion and adhesion, etc. , optics, electronics, medicine, environmental protection, biology and other fields, the emergence of vacuum low-temperature plasma cleaning equipment has enabled people to have a better understanding of the cleaning of their products in a vacuum environment. Some people may ask: "Why vacuum cleaning?" Because cleaning in a vacuum environment can achieve stronger processing results. The product is placed in a sealed cavity and continuously pumped. Assuming that there are small particles on the surface of the product, such as dust, they can be removed according to the continuous pumping time. The continuous pumping time means that the vacuum state must be maintained at a relatively stable vacuum state. In addition, the charging and discharging of low temperature plasma cleaning equipment must be in a stable vacuum environment.
The plasma surface treatment machine has low cost, simple and flexible operation, and can easily change the type of treatment gas and treatment process parameters; it will not cause any harm to the operator's body during use; for the treatment method of the plasma surface treatment machine, the cost is low , and has objective cost performance and advantages; from the perspective of environmental protection, the entire process of plasma surface treatment machine cleaning equipment is pollution-free, pollution-free, and green.
Most of the vacuum low temperature plasma cleaning machine equipment adopts vacuum drying to pump the oil pump cavity. Some applications are stand-alone, others are combined. Low temperature plasma cleaning machine, small and medium vacuum pump. The actual operation control panel is mainly composed of buttons, status indicators, passive buzzers and display lights, output power controllers, data display vacuum gauges, timers, knob switches and total float flow. It consists of the dashboard and other components. The start and stop control of the vacuum pump is an instant control of the DC contactor through a lockable on-off light-emitting key. The contact point of the DC type contactor is connected, and the three-phase power supply of the control vacuum pump is connected and disconnected. This control method can fully take into account the control requirements of small and medium-sized plasma cleaners. If this method is used to achieve fully automatic control, it is not only difficult, but also the accuracy requirements and control safety factors are difficult to specify.
The use of plasma surface treatment machine can keep operators away from the harm of harmful solvents to the human body, and also avoid the problem of easy damage to objects during wet cleaning; avoid the use of ODS harmful solvents, so that no harmful pollutants will be generated after washing, so it belongs to Environmentally friendly green cleaning methods have become increasingly important under the high attention of global environmental protection.
After the equipment is cleaned by the plasma surface treatment machine, the cleaning object is dry, and it can be sent to the next process without air-drying or drying treatment, which can improve the processing efficiency of the entire process pipeline. Plasma generated by high frequency is different from direct light such as laser. The direction of movement of the plasma is scattered, which allows it to penetrate into the small holes and depressions inside the object to complete various cleaning tasks, so the shape of the object being cleaned does not need to be considered too much. In addition, for these difficult-to-clean parts, the cleaning effect is similar or better than that of Freon.
Therefore, vacuum low-temperature plasma cleaning equipment is widely used in high-tech industries, especially in automobiles, semiconductors, microelectronics, integrated circuits, vacuum electronics and other industries. An indispensable link is the key to improving product quality.
The basic principle of most of the manual control is similar to the experimental vacuum low temperature plasma cleaner. Press the relative key to turn on the vacuum pump. The difference is that one key controls the hardware configuration and the other is controlled via virtual keys on the touch screen. The hardware configuration of the keyboard driver is the electromagnetic coil of the automobile relay and the soft element of the touch screen keyboard driver controller. On the basis of the logic measurement, the controller outputs the measurement results to the output terminal of the controller, the position of the small relay of the driver, the contact point of the driver, and the contact point of the AC vacuum pump. The contact point of the electromagnetic coil of the vacuum pump is connected to the contact point that is disconnected, so as to control the contact point of the three-phase power supply of the vacuum pump motor.
According to the application of vacuum low temperature plasma cleaning machine equipment in various industries, the plasma surface treatment machine has many advantages. Plasma plating, plasma coating, plasma ashing, surface modification, etc. have been widely used. Through its treatment, the wettability and adhesion of the material surface can be effectively improved, so that a variety of materials can be coated. Coating, coating and other operations, enhance the bonding ability and adhesion, and can also remove organic pollutants, oil or grease.
Fully automatic control means that all gestures are done fully automatically in the sequence of the keys. According to relatively logical standards, the vacuum pump is started and stopped in the control steps of the whole process. Whether it is manual control or fully automatic control, as long as the vacuum level is kept within a certain value, it cannot be measured only by the steam flowmeter. If the speed of the vacuum pump motor can be flexibly controlled, the vacuum can be easily controlled within the set range. When the vacuum degree of the inner cavity is less than or equal to the predetermined vacuum degree, according to the value, the speed ratio of the vacuum pump motor of the vacuum low-temperature plasma cleaning machine is completely automatically adjusted, so that the rated power of the motor is kept within the set vacuum degree range; The vacuum degree is affected by other factors, and when there is an error between the specific vacuum degree and the set vacuum degree, the program flow chart will automatically measure the speed of the vacuum pump so that it can maintain the set vacuum value. This is called PID control.
