1. The brake assembly line controller, which is the brain of the automated factory
The automatic production line controller refers to the master device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit according to a predetermined sequence to control the start, speed, brake and reverse of the motor.
It is composed of program counter, instruction register, instruction decoder, timing generator and operation controller. It is the "decision-making body" that issues orders, that is, it completes the coordination and command of the operation of the entire computer system. Commonly used controllers for automatic production lines are plc, industrial computer and so on.
Programmable logic controller, which uses a type of programmable memory for its internal storage program, performs user-oriented instructions such as logic operations, sequence control, timing, counting and arithmetic operations, and through digital or analog input/output Control various types of machinery or production processes.
2. Servo motor, the muscle that servo motor provides power for automatic production line
Servo motor refers to the engine that controls the operation of mechanical components in a servo system, and is an indirect gear change device for auxiliary motors. The servo motor can control the speed and position accuracy very accurately, and 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 react 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. Converted into angular displacement or angular velocity output on the motor shaft. Servo motors are divided into two categories: DC and AC servo motors. The main feature is that there is no rotation when the signal voltage is zero, and the speed decreases at a uniform speed with the increase of torque.
3.the sensor, the sensor is the tactile sense of the automatic production line
A sensor is a detection device that can feel the information being measured, and can transform the sensed information into electrical signals or other required forms of information output according to a certain rule to meet the transmission, processing, storage, and display of information , Recording and control requirements. Automatic production line is the first link 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 to make the equipment work in a normal or optimal state, and to make the products reach the best quality. Therefore, it can be said that without many excellent sensors, modern production will lose its foundation.
