In fact, in real life, artificial intelligence is indeed in many aspects of invasion of human life, industrial robots are one of the common of them.Lets take a look at the technical principles of industrial robots with Xiaobian?What is its structure like.
Structure classification of industrial robots
Industrial robots are composed of three basic parts: subject, driver system and control system.The main body is the seat and the execution agency, including the arm, the wrist and the hand, and some robots also have walking agencies.Most industrial robots have 3 to 6 exercise freedom, of which 1 to 3 motion freedoms are usually 1 to 3; the driving system includes power devices and transmission mechanisms to make the execution agency generate corresponding actions; the control system is input according to the inputThe program sends instruction signals to the driver system and execution agency and controls it.
Industrial robots are divided into four types of movement in the arms.The arms of the right -angle coordinate can be moved along three right -angle coordinates; the arms of the cylindrical coordinate can be lifted, rotating and telescopic action;Turn the joint.
Industrial robots can control the control functions of the execution agency movement, and can also be divided into position and continuous trajectory type.Point -level control only controls the execution agency from one point to another accurate positioning, suitable for machine tools, point welding, general handling, loading and unloading, etc.And paint and other homework.
Industrial robots are divided into two types: programming input type and teaching input type according to the program input.Programming input type is to transmit the operating program files that have been compiled on the computer and transmit them to the robot control cabinet through the RS232 serial port or Ethernet.
There are two types of teaching input -type input types: one is to use the manual controller (the manipulation box) of the operator to pass the instruction signal to the driver system, so that the execution agency will be performed in accordance with the required action order and movement trajectory.The other is to directly lead the execution agency by the operator to exercise the order of action and movement in accordance with the required action order.While showing the teaching process, when the information of the working program is automatically stored in the program memory, the control system detects the corresponding information from the program memory, pass the instruction signal to the driver, so that the execution agency will reproduce the teaching of the teaching agency.Various actions.Industrial robots that demonstrate input programs are called religious reproduction industrial robots.
Industrial robots with a sense of tactile, force consciousness, or simple vision can work in a more complex environment; if they have recognition functions or further increase their adaptive and self -learning functions, they become smart industrial robots.It can adapt to the environment in accordance with the "macro instructions" given by people to adapt to the environment and automatically complete more complicated work.
Technical principles of industrial robots
The robot control system is the brain of the robot and the main factor that determines the function and performance of the robot.
The main task of industrial robotics technology industrial robot control technology is to control the movement position, posture and trajectory of industrial robots in the working space.It has the characteristics of simple programming, software menu operation, friendly man -machine interaction interface, online operation prompts and convenient use.[2]
Key technologies include:
(1) Open modular control system architecture: use a distributed CPU computer structure, divided into robotic controller (RC), motion controller (MC), photoelectric isolation I/O control board, sensor processing board and programming instructionsTeach box and so on.Robot controllers (RC) and programming instruction boxes communicate through serial port/CAN bus.The main computer of the robot controller (RC) completes the robots motion planning, interpolation and location servo, and the functions of the main control logic, digital I/O, sensor processing and other functions, while programming the texture box completes the display of the information and the input of the keys.
(2) Modular hierarchical control software system: The software system is based on open source real -time multi -tasking operating system Linux, which uses layered and modular structure design to realize the openness of the software system.The entire controller software system is divided into three levels: hardware driving layer, core layer and application layer.The three levels face different functional needs and correspond to the development of different levels. Each level of the system is composed of several compact modules with several functions. These functional modules cooperate with each other to implement the functions provided by this level.
(3) Failure diagnosis and security maintenance technology of robotics: Through various information, diagnosis of robotic faults, and performing corresponding maintenance is a key technology for ensuring the safety of robotics.
(4) Network robotic controller technology: The current application engineering of the robot is developed from a single robot workstation to the robot production line. The networking technology of the robot controller has become more and more important.The controller has the network function of serial ports, on -site bus and Ethernet.The communication that can be used between robotic controllers and robotic controllers with the upper machine, which is convenient for the robot production line to monitor, diagnose and manage
Application of industrial robots
Typical applications of industrial robots include welding, paint, assembly, collection, and placement (such as packaging, palletization and SMT), product testing and testing; the completion of all tasks is efficient, durable, speed and accuracy.
1. Transfer line
Robot and conveying line logistics automation systems are mainly composed of the following parts: automated conveying lines, robot systems, automated stereo storage supplier systems, main control systems throughout the line, barcode data collection system, product automation test system, production line monitoring/scheduling/managementsystem.
Robotic and conveying line logistics automation systems can be applied to building materials, home appliances, electronics, chemical fiber, automobiles, food and other industries.
2. Applying glue
Robotic gum workstation is a robot application system developed and developed by the Robotic Center, mainly including robotics, glue system, glue workbench, workstation control system, and other surrounding supporting equipment.
The workstation has a high degree of automation and is suitable for multi -varieties and large -scale production. It can be widely used in industries such as automotive windshield, car motorcycle car lights, building materials doors and windows, solar photovoltaic batteries.
3. Welding
This system generally uses melting polar gas protection welding (Mig, MAG, CO2 welding) or non -melting polar gas protection welding (Tig, plasma arc welding).The equipment generally includes: welding power supply, welded and wire delivery mechanism, welding robot system and corresponding welding software and other auxiliary equipment.
Automatic robot welding workstations can be widely used in various industries such as railway, aerospace, military industry, metallurgy, automobiles, and electrical appliances.
4. Automatic boxing

Robotics can be used for automatic boxing and palletizing workstations.
5. Automatic welding
The turning shaft automatic welding workstation is used to weld the various types of workpieces with a shaft as the base (top -up cantilever). It consists of a welding robot, a rotary dual -station transformer (several stations) and the workmade fixture.By using different fixtures, multi -variety of automatic welding can be achieved, and the relative position accuracy of welding is high.
It can be widely used in various types of workpieces with high -quality and high -precision shafts as the base. It is suitable for power, electrical, machinery, automobiles and other industries.
