I. Controller
Automatic production line - the brain of an automated factory
The 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 start, speed regulation, braking and reverse of the motor in a predetermined order. It is composed of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is the "decision-making body" for issuing commands, that is, to complete the coordination and command of the operation of the entire computer system. The controllers commonly used in LED production line include PLC, IPC and so on. Programmable logic controllers (PLCs) use a class of programmable memory for their internal stored programs to execute user-oriented instructions such as logical operations, sequential control, timing, counting, and arithmetic operations, and to control various types of mechanical or production processes through digital or analog input/output.

Second, industrial robots
Automatic production line - automated factory operator
A robot is a mechanical device that performs its work automatically. It can be commanded by humans and run preprogrammed programs, and the LED production line can operate according to principles laid out in artificial intelligence. Its task is to assist or replace human work, such as manufacturing, construction, or dangerous work. Robots are generally composed of actuators, driving devices, detection devices, control systems and complex machinery.

Three, servo motor
Automated production line - Automated factory provides power to the muscles
Servo motor refers to the engine that controls the operation of mechanical components in the servo system. It is a kind of indirect speed change device for auxiliary motor. Servo motor can control the speed, position accuracy is very accurate, 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 the executive component, and has the characteristics of small electromechanical time constant, high linearity, starting voltage and so on. The received electrical signal can be converted into the output of angular displacement or angular speed on the motor shaft. It is divided into DC and AC servo motors. Its main characteristic is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases uniformly with the increase of the torque.

Four, the sensor
Automatic production line - automated factory touch
Sensor is a detection device, can feel the measured information, and can feel the information, according to certain rules into electrical signals or other required forms of information output, to meet the information transmission, processing, storage, display, record and control requirements. It is the first step to realize automatic detection and automatic control. In modern industrial production, especially in the process of automatic production, various sensors should be used to monitor and control each parameter in the production process, so that the equipment works in the normal state or {zj0} state, and make the product reach the quality of {zh0}. Therefore, it can be said that without numerous excellent sensors, modern production will lose its foundation.
