Question 17

Electronic Flow Valve

Accepted Answer

What is an Electronic Flow Valve?

An Electronic Flow Valve is a device that is able to control the flow rate of fluid (liquid and gas) with electronic signal. Ideally, the output flow rate is linearly proportional to input signal. Depend on the type of medial it is regulating, when it’s air, it is called electronic flow regulator, electronic air flow control valve, electronic pneumatic flow control valve; and when the media is water, it’s called electronic water flow control valve, digital flow control valve, digital flow controller, or proportional needle valve for both types.

There are different types of working principle, and in this article we will be introducing you the proportional needle valve type driven by a stepper motor powered linear actuator. We will firstly introduce you what type of electronic flow valve we offer, followed by the working principle and with what is the main advantage of KaoLu’s proportional needle valve, and then conclude with what you should think about before purchasing an electronic flow valve.

What type of Electronic Flow Valve does KaoLu offer?

KaoLu offers 5 types of digital flow control valve. One advantage is that it can control both gas and liquid. Please click on the photo link below for further information

FC20 : Flow rate up to 45 L/min of nitrogen gas @ 6 bar or 750 mL/min of water @ 6 bar
FC120: Flow rate up to 200 L/min of nitrogen gas @ 6 bar or 3.5 L/min of water @ 6 bar
FC300: Flow rate up to 450 L/min of nitrogen gas @ 6 bar or 8 L/min of water @ 6 bar
FC1000: Flow rate up to 650 L/min of nitrogen gas @ 5 bar or 12 L/min of water @ 5 bar
FC2000: Flow rate up to 2000 L/min of nitrogen gas @ 5 bar or 30 L/min of water @ 5 bar

What is working principle of an Electronic Flow Regulator?

There are different types of Electronic Flow Regulator. Here we will be explaining the type that utilizes a linear stepper motor actuator and proportional needle valve.

So, what is the advantage of KaoLu’s electronic air flow control valve or electronic water flow control valve?

Our parameters tells all the story. With FC series electronic flow valve, we are able to withstand 7 bar of perpendicular operating pressure, with a resolution as high as 20 mL/min of air, repeatability of 0.1% F.S, and 0.1% of linearity. This is due to the motor we used, the extremely low tolerance of mechanical parts, the fine thread needle we used which is extremely difficult to reproduce by others, and the control system we designed.

What should you consider when purchasing an electronic flow regulator?

You should consider 3 main factors ( we called CPR)

Compatibility: Medium, flow range, compatibility with the valve material, and operating pressure
Performance: Resolution, starting flow point, and linearity
Control system

It is important to understand whether the media you used falls into the flow range of the operating valve. As each media has different density so the flow range would be different from the nominal flow range. Next is whether the media used is compatible with the wet material and whether you would also need the body to be special material. The operating pressure is another caveat, where if you simply needs flow control, sometimes it would not be a very important factor.

Next is the performance, with some applications that needs fine control and adjustment between steps, such as laser cutting, the resolution dictated by the control logic and motor performance plays an important role here. Furthermore, as the motion system requires to overcome initial inertia, the start flow point is should be considered.

Then comes the control system where the you should check what type of control system do suppliers offer? Here we provide an external driver that has a cable connected to the control valve. The great advantage that we offer is that should you want to operate the valve from distant away from the site, we offer RS485 modbus where you could control the valve up to half a mile away from the valve.

We hope you have enjoyed reading the article, understand about stepper motor driver electronic flow control valve, understand about our products, and finally help you with selecting the right valve.

Question 18

Screen printing of electronic air pressure regulator

Accepted Answer

At present, silicon solar cells occupy most market of photovoltaic power, and are very important in terms of efficiency improvement and cost control. As an important part of silicon battery production, the screen printing of silicon battery electrodes directly affects the competitiveness of screen printing equipment in the market on the accuracy, efficiency and cost of printing equipment.

Screen printing is to attach a stencil with an image or a pattern to the screen for printing. When the substrate is placed directly under the screen with the stencil, the screen printing ink or paint passes through the extrusion of the squeegee. The mesh in the middle of the screen is printed on the carrier. One of the most important steps is the precision and pressure of the squeegee drop, which directly affects the layer thickness and shape of the printing, and even causes the silicon wafer to be damaged because the drop distance of the squeegee is too large. Therefore, the control of the squeegee is an important part of screen printing. The proportional pressure valve manufactured by KaoLu provides a comprehensive solution for screen printing equipment manufacturers with the advantages of high precision and high response.

KaoLu’s electronic air pressure regulator controls the corresponding pressure by controlling the input signal, and the output controls the corresponding movement of the cylinder to push the scraper speed to accurately drop to the required height, and transmit it to the controller in real time through the feedback signal. This is a method of pre-calculating the electronic air pressure regulator, which uses the linear characteristics of the electronic air pressure regulator to accurately control the pressure of screen printing blade to meet the accuracy required by the power system of screen printing machine. KaoLu’s electronic air pressure regulator adopts new technology, which enables it to achieve high control accuracy, and is widely used in the printing industry at present. KaoLu’s electronic air pressure regulator uses pneumatic components and semiconductor sensors to improve accuracy and response by adjusting the proportional pressure signal. The pressure control system of screen printing machine is composed of a electronic air pressure regulator, a screen printing scraper, a touch screen, a cylinder and a programmable logic controller. The schematic diagram is as follows:

Set the working pressure of silk screen scraper on the touch screen, the PLC controller will calculate and convert it into the digital quantity required by the analog output module, and the analog output module will output a certain voltage value to the proportional pressure valve. The electronic air pressure regulator will output the pressure according to the voltage signal, and the internal pressure sensor detects that the set pressure value is reached, that is, the pressure adjustment is completed.

Proportional pressure valves are not only used in the screen printing machine industry, but KaoLu’s electronic air pressure regulator can be widely used in industrial applications, automotive industry, inkjet industry and blow molding industry.

Question 19

Application of proportional pressure regulator in Bonding Machine

Accepted Answer

The function of bonding machine is to directly bond the flexible circuit board or cable to the electrodes on the edge of liquid crystal glass. That is, the process of installing flexible circuit boards and cables on liquid crystal glass. Therefore, the quality of bonding machine will directly affect the productivity of LCD glass and the service life of the LCD screen.

Technical parameters of bonding machine:
1. Air source pressure: 0.5~0.7MPa
2. Binding pressure: 3~40Kgf
3. Pressure accuracy: ±0.2Kgf
4. Binding temperature: RT~499℃
5. Hot pressure time: 1~99 S 6. Hot pressure accuracy: 0.14mm

The working process of bonding machine:
1. ACF pre-paste: Under the pressure and temperature by working requirement, the flexible circuit board (FPC) and the liquid crystal glass need to be bonded to the pins of ACF with a specified length, and the surface should be flat and free of air bubbles.

2. Pre-bonding: Align the pins of FPC and the liquid crystal glass through the CCD camera, and pre-press at the required pressure and temperature to form a preliminary connection. In this step, the alignment of CCD camera is an important link. As the pitch of lifting leads is getting smaller and smaller in production, the small pitch has reached 0.05MM, and the alignment accuracy should be within ±0.005mm.

3. Main bonding: Under the required pressure and temperature, the pre-bonded LCD screen is subjected to the main bonding by using a pulse hot press. At the same time, the glue in the ACF is polymerized and hardened at high temperature to form a strong physical connection between the two different materials.

Detection of bonding machine: The LCD screen after the main bonding is detected through CCD camera.
1. Temperature control: The heating rate and the maximum temperature are both important factors affecting the curing of ACF. The heating rate determines the surface quality of ACF after curing, and the maximum temperature determines the bonding strength of ACF after curing.

2. Flatness of the bonding head: The unevenness of the bonding head causes the ACF conductive particles to be unevenly broken, because the ACF conductive particles are very small, usually about 4um in diameter, and the ACF is very sensitive to pressure. When the contact surface of the bonding head is not flat, part of the ACF conductive particles will be completely broken, while another part of the ACF conductive particles will not be broken normally, resulting in poor electrical conductivity between the liquid crystal glass and the FPC.

Proportional pressure regulator control principle:

1. When the equipment is in standby, the solenoid valve controls the cylinder to rise, and the proportional valve is in the exhaust state.

2. When working, the solenoid valve controls the cylinder to descend, and the proportional valve controls the pressure when the cylinder descends. The proportional valve can be adjusted in real time according to the bonding process.

Question 20

Application of Proportional Pressure Regulator in Dispensing Industry

Accepted Answer

In recent years, with the rapid development of industrial robots and industrial automation, it has promoted the development of dispenser technology and the demand for dispenser equipment in downstream markets, such as: 3C electronics, automotive, etc. For dispensing equipment manufacturers, in addition to making the equipment highly intelligent, it is also necessary to ensure the stability of dispensing control system and the precise control of quantity.

With the continuous improvement of technical requirements in the dispensing industry, the stability of glue volume is very important. Proportional pressure regulators have become an integral part of modern dispensing equipment and dispensing controllers. With the advantages of high precision and high stability, the proportional pressure regulators made by KaoLu enables the dispensing machine to precisely control the amount of glue dispensed from the needle.

KaoLu’s proportional pressure regulators controls the corresponding pressure output of proportional pressure valve by controlling the input signal. When gas enters the main valve through the air inlet, the air inlet is isolated from the air outlet due to the sealing of valve core, so that the gas enters the pilot valve through the corresponding flow channel. The gas pressure changes, and the gas flowing out of pilot valve passes through another flow channel, pushing the valve core to move down, so that the air inlet and the air outlet are connected. At this time, the pressure sensor will detect the outlet pressure, and transmit the data to processor. The processor compares the difference between actual pressure value and calibrated pressure value, and dynamically adjusts the pressure to be the same.
