  The automated production line is formed on the basis of the further development of the continuous assembly line. Its characteristics are: the processing object is automatically transferred from one machine tool to another machine tool, and the machine tool automatically performs processing, loading and unloading, inspection, etc.; the worker's task is only to adjust, supervise and manage the automatic line, and does not participate in direct operation; all The machinery and equipment all operate in a unified rhythm, and the production process is highly continuous. The main components that enable the automatic production line to run freely and function are the following ten components.

The role of the main components of the automated production line

  1. Automated production line controller, which is the brain of the automated factory

  The automatic production line 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.

  Composed of program counters, instruction registers, instruction decoders, timing generators, and operation controllers, it is the "decision-making body" that issues commands, that is, to coordinate and direct the operation of the entire computer system. Commonly used controllers in automatic production lines include plc, industrial computer, etc.

  Programmable logic controller, which uses a type of programmable memory for its internal storage program, executes user-oriented instructions such as logic operations, sequence control, timing, counting and arithmetic operations, and uses digital or analog input/output Control various types of machinery or production processes.

  2. Servo motor, the muscle that servo motor powers the automatic production line

  Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is an auxiliary motor indirect speed change device. The servo motor can control the speed and the position accuracy is very accurate, 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 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. Converted to angular displacement or angular velocity output on the motor shaft. Servo motors are divided into two categories: DC and AC servo motors. Their main characteristics are that there is no self-rotation phenomenon when the signal voltage is zero, and the speed decreases at a uniform speed with the increase of torque.

  3. Sensor, the sensor is the sense of touch of the automated production line

  A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the needs of information transmission, processing, storage, and display. , recording and control requirements. The automatic production line is the primary 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, so that the equipment can work in a normal or optimal state, and the product can achieve the best quality. Therefore, it can be said that without many excellent sensors, modern production will lose its foundation.
