1.Robots: performers of unmanned automated production lines
Robot, a robot is a machine that performs tasks automatically. It can either accept human command, run pre-programmed programs, or act in accordance with principles formulated by artificial intelligence technology.
Its task is to assist or replace human work, such as production, construction, or dangerous work. Robots are generally composed of actuators, driving devices, detection devices and control systems and complex machinery.
2.Controller: the brain of unmanned automated production line
Controller (English name: controller) refers to the main command device that changes the wiring of the main circuit or control circuit and changes the resistance value in the circuit to control the starting, speed regulation, braking and reverse of the motor in a predetermined order.
It consists of a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller. It is a “decision making body” that issues commands, that is, it coordinates and directs the operation of the entire computer system.
Programmable logic controller (PLC), which uses a type of programmable memory for its internal storage programs, performs logic operations, sequence control, timing, counting and arithmetic operations, and other user-oriented instructions. Digital or analog input / output controls various types of machinery or production processes.
3.Sensing: Haptics in unmanned automated production line
A sensor is a detection device that can sense the measured information, and can transform the sensed information into electrical signals or other required forms of information output in accordance with a certain rule to meet the transmission, cnc machining, storage, and display of information , Records, and controls.
It is the first step to realize automatic detection and automatic control.
In modern industrial production, especially in the automated production process, various sensors are used to monitor and control various parameters in the production process, so that the equipment works in the normal state or the best state, and the product reaches the best quality. Therefore, it can be said that without many excellent sensors, modern production has lost its foundation.
4.Servo motor: muscle powered by unmanned automated production line
Servomotor (servomotor) refers to the engine that controls the operation of mechanical components in the servo system. It is an auxiliary motor indirect speed change device.
The servo motor can control the speed and position accuracy. It can convert the voltage signal into torque and speed to drive the control object.
The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant, high linearity, and starting voltage. It can convert the received electrical signal Converted into angular displacement or angular velocity output on the motor shaft.
Is divided into two categories, DC and AC servo motors. Its main characteristics are that there is no rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque.
5.Solenoid valve: switch for unmanned automated production line
Electromagnetic valve (Electromagnetic valve) is an industrial device controlled by electromagnetics. It is an automatic basic component used to control fluids. It belongs to actuators and is not limited to hydraulic and pneumatic.
It is used in industrial control system to adjust the direction, flow rate, speed and other parameters of the medium. The solenoid valve can be used with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed.
There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used are check valves, safety valves, directional control valves, speed regulating valves, etc.
6.Inverter: switcher for unmanned automated production line
Variable-frequency drive (VFD) is a power control device that applies AC frequency conversion technology and microelectronic technology to control the AC motor by changing the frequency of the motor’s working power.
Inverter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking unit, driving unit, detection unit and micro machining unit.
The inverter relies on the opening and closing of the internal IGBT to adjust the voltage and frequency of the output power, and provides the required power voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the inverter also has many protection functions , Such as overcurrent, overvoltage, overload protection and so on.
7.Instruments: Regulation system of unmanned automated production line
Instrumentation (English: instrumentation) Instrumentation is an instrument or device used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments. In the unmanned automated production line, various instruments and meters are needed, such as measuring the parameter values required for some control processes such as pressure, liquid level, flow rate, and temperature. Related instruments and meters are required.
8.Automation software: the heart of unmanned automated production line
Because of the integration of industrial control system management and control trend engineering network copyright, the industrial control system is connected with traditional IT management systems and the Internet, and more and more common software, hardware and protocols are used internally. More common is SCADA automation software.
9.Industrial cameras: glasses for unmanned automated production lines
Industrial camera is a key component in machine vision system. Its most essential function is to convert light signals into AFT-808 small high-definition industrial cameras as ordered electrical signals.
The industrial camera is generally installed on the machine assembly line instead of the human eye for measurement and judgment. It is converted into an image signal through a digital image capture target and transmitted to a dedicated image machining system.
The image system performs various operations on these signals to extract the features of the target, and then controls the field equipment operations based on the results of the discrimination.
