Industrial intelligent robot -- the common robot used in the industrial environment and the problems often encountered when working. What can be considered as an industrial intelligent robot? Not every electromechanical device used in an industrial environment can be considered a robot. According to the definition of international standards organization, industrial intelligent robot is a kind of programmable multi-purpose manipulator with three degrees of freedom or multi axis automatic control, which is almost accepted when talking about industrial robots.
Industrial intelligent robot
What has changed since the emergence of industrial robots? More and more industrial robot engineers and entrepreneurs are looking for more and more robot technologies to help optimize workflow in industrial environments. With the development of the times and the progress of robot technology, robot arm paves the way for novices such as group AGV used in storage.
We often say that a typical industrial robot consists of tools, industrial robot arms, control cabinets, control panels, teaching aids and other peripherals. So what are these? These parts are usually together, and the control cabinet is similar to the brain of a robot. The control panel and teaching device constitute the user environment.
1、 Core components of industrial robot
1. Reducer
According to different structures, precision reducers for industrial robots can be divided into five categories. RV Reducer and harmonic reducer are the most popular precision reducer for industrial robots. According to the different structure, precision reducer can be divided into five types: harmonic gear reducer, cycloidal pin gear planetary reducer, RV Reducer, precision planetary reducer and filter gear reducer.
They are different in precision, torque, stiffness and transmission efficiency. Among them, RV Reducer and harmonic reducer are the mainstream precision reducer of industrial robot.
2. Servo motor
The requirements of joint driving motor are very strict for robot. AC servo motor is widely used in industrial robot.
At present, the domestic high-end market is mainly occupied by foreign famous enterprises, mainly from Japan, Europe and the United States, so there is a large space for domestic substitution in the future. At present, foreign brands account for nearly 80% of China's AC servo market, mainly from Japan, Europe and the United States.
Among them, Japanese products take the first place in the market share of about 50%, and its famous brands include Panasonic, Mitsubishi Electric, Yaskawa, Sanyo, Fuji, etc. the characteristics of its products are that the technology and performance level are more in line with the needs of Chinese users, with good cost performance and high reliability, it has a stable and continuous customer source, especially in the small and medium-sized OEM market.
3. Controller
The software part of robot controller is the "heart" of industrial robot. With the development of science and technology, there are different degrees of research results in the application software of industrial robot from the lower computer to the upper computer.
The controller, software and ontology are generally independently designed and developed by robot manufacturers. At present, the controllers of foreign mainstream robot manufacturers are independently developed on the basis of general multi axis motion controller platform, and each brand of robot has its own control system to match it. Therefore, the market share of the controller is basically consistent with that of the robot, and the domestic enterprise controller has not yet formed the market competitive advantage
The robot controller products of domestic enterprises have been mature, which is the key component of robot products with small gap with foreign products. The gap between domestic controllers and foreign products mainly lies in the control algorithm and the ease of use of secondary development platform.
In the next few years, China's domestic robots will get rapid development, and the application market of domestic robot controllers will face a good development opportunity, especially the enterprises that have been deeply engaged in the field of motion control for many years. The more the number of robot axes, the higher the performance requirements of the controller: the degree of freedom of the robot depends on the number of movable joints. The more joints, the higher the degree of freedom and the higher the displacement accuracy, the more servo motors are used, that is, the more precise the industrial robots use the more servo motors.
Generally, each multi axis robot is controlled by a set of control system, which means that the higher the performance requirements of the controller. With the rapid development of industrial robots in China, companies with strong R & D capabilities will have stronger competitive advantages.
2、 Industrial robot body
Since the birth of the first industrial robot in 1958, the development of robot has experienced a small climax. In the late 1980s, due to the saturation of industrial robot application by traditional robot users, industrial robot products were overstocked, many robot manufacturers closed down or were merged, and the international robotics research and robot industry was in a depression.
In the early 1990s, the robot industry showed signs of recovery and continued development. Since 1995, the number of robots in the world has increased year by year with a high growth rate.
