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.
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.
4. The automation software of the automatic production line is the heart of the automatic production line
Due to the integration of management and control of the industrial control system, Trend Control Engineering Network copyright, the industrial control system is connected with the traditional IT management system and the Internet, and more and more general-purpose software, general-purpose hardware and general-purpose protocols are used internally.
SCADA automation software is more common in automated production lines.
The SCADA automation system is what we call a data acquisition and monitoring system. It is mainly supported by computer technology, and it is a system for scheduling and automatic control of various production processes. SCADA automation software can automatically and accurately monitor production for a long time without being supervised, and obtain effective information data from it, providing a powerful evaluation reference for supervisory managers.
5. Inverter, the inverter is the switch on the automatic production line
Inverter is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's operating power supply. The frequency converter is mainly composed of rectification (AC to DC), filter, inverter (DC to AC), braking unit, drive unit, detection unit, micro-processing unit, etc. It adjusts the voltage and frequency of the output power supply by switching off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the inverter has many protection functions. Such as overcurrent, overvoltage, overload protection and so on.
6. Control cabinet, the control cabinet is the central system of the automatic production line
There are many kinds of control cabinets, including electrical control cabinets, frequency conversion control cabinets, low-voltage control cabinets, high-voltage control cabinets, water pump control cabinets, power supply control cabinets, explosion-proof control cabinets, elevator control cabinets, PLC control cabinets, fire control cabinets, and brick machines. control cabinet and so on.
The automatic production line involves electrical, frequency conversion, power supply, water pump and other control cabinets. Different control cabinets are selected according to different needs to achieve different control functions.
7. Solenoid valve, the solenoid valve is the switch of the automatic production line
Solenoid valve is an industrial equipment controlled by electromagnetism. It is an automatic basic component used to control fluid. It belongs to actuator and is not limited to hydraulic and pneumatic. Solenoid valves are used in industrial control systems to adjust the direction, flow, speed and other parameters of media. It can cooperate with different circuits to achieve expected control, and the control accuracy and flexibility 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 ones are check valves, safety valves, directional control valves, and speed regulating valves.
8. Instrumentation, instrumentation is the adjustment system of the automatic production line
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 measuring instruments, microscopes, multipliers, etc. are all instruments.
Various instruments and meters need to be applied in the automated production line, such as measuring pressure, liquid level, flow rate, temperature and other parameters required for the control process, and related instruments and meters are required.
9. Industrial cameras, industrial cameras are glasses for automated production lines
The industrial camera is a key component in the machine vision system. Its most essential function is to convert the optical signal into an orderly electrical signal.
Industrial cameras are generally installed on machine assembly lines to replace human eyes for measurement and judgment, and digital image capture targets are converted into image signals and sent to a dedicated image processing system. The image system performs various calculations on these signals to extract the characteristics of the target, and then controls the action of the equipment on the spot according to the result of the discrimination.
10. Robot, the robot is the specific executor on the automated production line
A robot is a mechanical device that performs work automatically. It can accept human command, run pre-programmed programs, and act according to principles and programs formulated with artificial intelligence technology. Its task is to assist or replace human work in jobs such as manufacturing, construction, or dangerous jobs. Robots are generally composed of actuators, driving devices, detection devices, control systems and complex machinery.
