Vacuum low temperature plasma cleaning machine vacuum pump operation on the role of cleaning effect

Vacuum low temperature plasma cleaning machine vacuum pump operation on the role of cleaning effect

Vacuum pump is the key component of vacuum low-temperature plasma cleaning machine. Its role is to vacuum the cavity material to achieve the effect of cleaning activation or improve adhesion, but do you know how to control in the vacuum low temperature plasma cleaning machine, so as to achieve a good practical effect? The use of vacuum low-temperature plasma cleaning machine makes people have a certain understanding of product cleaning under vacuum environment. One might ask, "Why vacuum cleaning?" Because cleaning in a vacuum environment can achieve a stronger treatment effect. The product is placed in a sealed chamber for a sustained period of time. If there are small particles such as dust on the surface of the product, it will be removed according to the continuous pumping time. Duration here means that you have to keep the vacuum situation at a relatively stable vacuum state. In addition, the charging and discharging of low-temperature plasma cleaning equipment must be carried out in a stable vacuum environment. 1. Control mode of vacuum pump of small vacuum low temperature plasma cleaning machine: Most vacuum plasma cleaning machines use vacuum pumps to remove dry, gas pump chamber. Some applications are standalone and some are combined pumps. Small and medium vacuum low temperature plasma cleaning machine adopts independent pump. Its actual operation control panel key consists of keys, status indicator, passive buzzer with display light, output power controller, data display vacuum gauge, timer, knob switch and total flow of float ball. This is made up of dashboards and other components. The start and stop control of the vacuum pump is the immediate control of the DC contactor by means of a lock activated light out button. DC contactor contact point connection and disconnection control vacuum pump three-phase power supply connection and disconnection. This control method can fully take into account the control provisions of small and medium-sized plasma cleaning machine. If this method is used for automatic control, it is not only difficult, but also difficult to stipulate the precision and safety factor of control. 2. On-line and sliding door type vacuum low-temperature plasma cleaning machine vacuum pump control method: Vacuum plasma cleaners are commonly used for linear and manual doors. The vacuum pump used is 1, 2. They are actually operated and controlled by touch screen. This control mode is divided into manual control and full automatic control. 3. Manual control mode: The basic principle of most manual controls is similar to that of the test vacuum cryogenic plasma cleaner. Press the relative button to turn on the vacuum pump. The difference is that one is controlled by hardware-configured keys, while the other is controlled by virtual keys on a touch screen. The hardware of the key driver is configured as the electromagnetic coil of the automobile relay, while the soft element of the touch-screen key driver controller. Based on the logical measurement, the controller outputs the results to the output terminal of the controller, the position of the small relay of the driver, and the contact point of the small relay of the alternating vacuum pump of the driver. The contact point of the electromagnetic coil of the vacuum pump is connected and disconnected, so as to control the three-phase power supply of the vacuum pump motor. 4. Full automatic control mode: Fully automatic control refers to the automatic execution of all positions according to the order of keys. According to the standard of relative logic, the vacuum pump is started and stopped in the control step of the whole process. Whether manual control or automatic control, assuming that the vacuum degree is maintained at a certain value, steam flowmeter alone can not meet the requirements. If you can easily control the speed of the vacuum pump motor, you can easily control the vacuum degree within the set scope. If the vacuum degree of the inner cavity is less than or equal to the preset value, the speed ratio of the vacuum pump motor of the vacuum low-temperature plasma cleaning machine is completely automatically adjusted according to the value, so that the rated power of the motor is kept within the set vacuum degree range; If the vacuum degree of the inner cavity is affected by other factors, and if there is an error between the specific vacuum degree and the set vacuum degree, the program flow will automatically measure the speed of the vacuum pump and automatically adjust to maintain the set vacuum value. This control is called PID control. P is the proportion effect, I is the integral effect, and D is the differential effect. PID not only has the rapid proportion effect, but also has the error clearance effect of integral effect and the regulation effect of differentiation effect. When the error step occurs, the guidance funct

The role of lithium battery plasma surface treatment equipment in the battery manufacturing process

The role of lithium battery plasma surface treatment equipment in the battery manufacturing process

Power lithium battery is a kind of commonly used lithium battery which is powered by pneumatic tool display driving force. This is a clean and environment-friendly driving power supply. In today's application scenarios, it is widely used in pure electric vehicles, electric trains, electric vehicles and so on. In recent years, with the rise of new energy vehicle sales market, the safety and reliability of power lithium battery has become a topic of concern and discussion. The reason lies not only in the fact that power lithium-ion battery is the key component of power drive system software, but also in the fact that the production process of power lithium-ion battery itself has high reliability and reliability requirements. Take automotive lithium battery as an example. What role can plasma surface treatment equipment play in the manufacturing process of power lithium battery? What can be done to help? In the manufacturing process of automotive power lithium battery, the surface treatment of plasma surface treatment equipment is generally carried out from three levels, that is, to improve the lubrication performance of the ceramic film before the positive and negative plate coating; The cleaning of the connection before lithium welding; As well as improving the surface adhesion of insulation board, end board, PET plastic film and other metal composite materials and their insulation materials before external adhesion of them and their lithium battery components. Next, I'll summarize briefly, and then go into more detail one by one. 1. Plasma surface treatment equipment to solve the problem of positive and negative two-stage coating in front of ceramic membrane plasma cleaning machine: The positive and negative grades of the automotive power lithium battery are made from the positive grades of the ceramic film and the cathode materials of the battery. Compared with ethanol and other aqueous solution cleaning, plasma cleaning machine treatment will not damage the raw material, and can remove the organic matter on the surface of the raw material, improve the lubrication of the film surface, improve the uniformity of the coating, heat resistance and safety factor. 2. Cleaning treatment of plasma surface treatment equipment before welding: The lithium connector is actually the part of the metal strip that correctly guides the positive and negative stages of the rechargeable battery. It is point contact during battery charging and discharging. Whether the surface of the connection is cleaned or not will do great harm to the reliability and performance of the electrical connection. Before electric welding, plasma cleaning machine can remove organic matter, particles and other residues on the weld surface, so that the weld surface becomes uneven, so as to improve the quality of welding. 3. Plasma surface treatment equipment for the treatment of lithium battery modules: Lithium-ion battery assembly is a process in which several rechargeable battery modules are connected in series into a series of parallel circuits to produce a lithium battery pack. In order to keep the power line and insulation layer safe, in this process, it is necessary to affixed external rechargeable batteries to improve the safety factor of the application. Before that, please use the plasma cleaning machine to clean the insulation board, end board, PET film and other parts. Isoionization treatment can thoroughly clean the dirt surface, make the surface become not smooth, and improve the adhesion of strong glue or strong glue. After years of development trend, China's power lithium battery industry chain has begun to take shape, but there are still some problems, such as technical strength and R&D ability is not strong, can not be fully utilized. It is believed that with the improvement of technical standards, the requirements of plasma surface treatment equipment will be put forward more detailed and diversified provisions.
