Keywords: industrial robots, applications, industrial
1 Introduction
Industrial robots were first used in the automobile manufacturing industry, commonly used in welding, painting, loading and unloading and handling. Industrial robots extend and expand the human hand, foot and brain functions, it can replace people engaged in dangerous, harmful, toxic, low temperature and high heat and other harsh environments; instead of people to complete the heavy, monotonous repetitive labor, improve labor productivity and ensure product quality. Industrial robots and CNC machining centers, automatic handling trolleys and automatic inspection systems can be composed of flexible manufacturing systems and computer-integrated manufacturing systems to achieve production automation.
2 The main use of industrial robots
(1) poor working environment and dangerous work in the military field and the nuclear industry, some of the work is harmful to human health and life-threatening, or a large number of factors of insecurity and should not be done by the people to do the work, with industrial robots to do the most appropriate. For example, the nuclear plant equipment inspection and maintenance robot, the nuclear industry on the boiling water reactor fuel automatic switch.
(2) special operations and extreme operations volcanic exploration, deep sea exploration and space exploration and other areas for human beings can not be reached, only robots can carry out operations. Such as the space shuttle used to recover the satellite operating arm; used for undersea mining and salvage remote control marine operations robot.
(3) the field of automated production of early industrial robots in production is mainly used for machine tools, materials, spot welding and painting. Used the most manufacturing industries including motor manufacturing, automobile manufacturing, plastic molding, general machinery manufacturing and metal processing industries. With the advent of flexible automation, robots play a more important role in automated production. The following is a brief introduction to the application of industrial robots in the field of automated production.
2.1 Welding robots
Spot welding robots industrial robots are first used in automotive spot welding operations, spot welding robots are widely used to weld the body of thin plate parts. Welding a car body generally need to complete about 3,000 to 4,000 welding points, of which 60% is completed by the spot welding robot. In some high-volume automotive production line, the number of point welding robots in service even up to more than 150.
The main performance requirements of spot welding robots: small installation area, large workpiece space; fast completion of small pitch multi-point positioning; high positioning accuracy (earth 0.25 mm) to ensure welding quality; hold a large (490 ~ 980N), in order to carry the internal transformer welding tongs; teaching is simple to save man hours.
2.2 Arc Welding Robot
Arc welding robots are used to weld metal continuous bonding of the weld process, the vast majority of which can be accomplished automatically wire feeding, melting electrodes and gas shielding under the welding work. Arc welding robots have a wide range of applications, in addition to the automotive industry, in general machinery, metal structures and many other industries. Arc welding robot should be a welding system including a variety of welding attachments, not just a single machine that moves with a planned speed and attitude carrying a welding torch. The basic components of an arc welding robot are shown in Figure 1. Suitable for robotic applications of arc welding methods mainly inert grip body protection welding, mixed body protection welding, submerged arc welding and plasma arc welding.

Figure 1 basic composition of the arc welding robot system
The main performance of the arc welding robot requires: In the arc welding operation, the welding robot is required to be able to weld the welds. In arc welding operation, the welding torch is required to track the movement of the weld channel of the workpiece and continuously fill the metal to form the weld channel. Therefore, the stability of the speed during the movement and trajectory are two important indicators, in general, the welding speed of about 5 ~ 50 mm / s, trajectory accuracy of about .2 ~ 0.5 ) mm; as the attitude of the torch also has a certain impact on the quality of the weld, so I hope to track the weld channel at the same time, the adjustable range of the torch attitude is as large as possible. In addition, there are a number of other performance requirements, these requirements include: setting the welding conditions (current, voltage, speed, etc.), dithering function, bevel filling function, welding anomaly detection function (arc break, workpiece melting) and welding sensors (start weld detection, weld path tracking) interface function.
2.3 Paint Spraying Robot
Paint spraying robots are widely used in automobile body, home appliances and various plastic products. Paint spraying robots in the use of the environment and action requirements have the following characteristics:
(1) the working environment contains explosive paint vapors in the air;
(2) along the trajectory of high-speed movement, passing through the points are operating points;
(3) most of the parts to be sprayed on a conveyor belt, while moving while spraying paint. As shown in Figure 2 for articulated painting robot.
2.4 Handling robots
With the development of computer integrated manufacturing technology, logistics technology, automatic warehousing technology, handling robots in the modern manufacturing industry is more and more widely used. Robots can be used in the processing of parts, materials, auxiliary gauges, loading and unloading and storage and transportation, can be used to send parts from one conveyor to another conveyor, or from a machine tool to remove the processed parts and then installed on another machine tool.
2.5 assembly robot
Assembly in modern industrial production occupies a very important position. Statistics show that assembly labor accounts for 50% to 60% of the product production labor, in some cases, this proportion is even higher. For example, in the electronic device factory chip assembly, circuit board production, assembly labor accounted for 70% to 80% of the product production labor. Therefore, it is very important to use robots to realize automated assembly operations.
2.6 Robotic Flexible Assembly System
The formal entry of robots into the field of assembly operations was in the ? The first year of robot popularization? Around 1980, the introduction of assembly robots were mainly used to replace manual work on the assembly line in the early days, followed quickly by the emergence of the robot as the main assembly line. The application of assembly robots greatly promoted the progress of assembly production automation. Assembly robots to establish a flexible automatic assembly system can automatically assemble small and medium-sized, moderately complex products, such as motors, pumps, gearboxes, etc., especially adapted to small and medium-sized mass production of assembly, can be realized automatically loading and unloading, transmission, testing, assembly, monitoring, judging, decision-making and other functions.
Robotic flexible assembly system is usually centered on the robot, and there are many peripheral devices, such as parts supply device, workpiece conveyor, fixture, applicator, etc. with it, in addition to often have interchangeable hands. However, if there are too many types of parts, the whole system will be too large and the efficiency will be reduced, which is not desirable. In a robotic flexible assembly system, the number of robots can be selected based on the production volume, while peripheral equipment such as parts supply units depends on the types of parts and work. Therefore, compared to an assembly line, the lower the output, the greater the investment in the robotic flexible assembly system.
3 Conclusion
Industrial robotics is based on machinery, electronics, electronic computers and automatic control and other subject areas of technology, the fusion of a system of technology; can also be said to be a knowledge, technology-intensive, multi-disciplinary cross-comprehensive high-tech. With the progress and development of these related disciplines, industrial robotics technology will also be to the rapid development and improvement.

First, the development of industrial robots
The first generation of robots, generally refers to a large number of industrial use of programmable robots and remote control operators. Programmable robots can be programmed according to the operator to complete some simple repetitive operations. Remote-control operators rely on the operator to send each step of the action. 1982, General Motors Corporation in the United States in the assembly line for the robot equipped with a vision system, thus announcing the second generation of robots - perception of the robot's introduction. This generation of robots, with external sensors, can be programmed offline. With the support of a sensing system, they have the ability to sense the environment to varying degrees and correct programs on their own. The third generation of robots is autonomous robots, which are being developed in various countries. It not only has the function of perception, but also has a certain decision-making and planning capabilities. According to the human command or in accordance with the environment to make their own decisions to plan the action that is programmed according to the task.
China's robotics research started late, from ? Seven-five? Beginning of the national investment in industrial machines and their components for research and development, completed the development and development of a complete set of demonstration and reproduction of industrial robotics technology. 1986 National High-tech Research and Development Program began to implement the theme of intelligent robots to track the world's robotics technology frontier, after several years of research, a large number of scientific research results, successfully developed a number of special robots.
China's industrial robots started in the early 1970s, after more than 30 years of development, roughly experienced three stages: the 70s of the budding period, the 80s of the development period and the 90s of the application of the period.
The 1970s was a milestone in the development of world science and technology: mankind landed on the moon, and realized the soft landing of Venus and Mars. China also launched an artificial satellite. The application of industrial robots in the world set off a climax, especially in Japan, the development of more rapid, which supplemented the growing shortage of labor. In this context, China began to develop its own industrial robots in 1972.
Into the 80's, under the impact of the wave of high technology, with the deepening of reform and opening up, China's robotics development and research has been the government's attention and support.? Seventh Five-Year? During the period, the state invested funds, industrial robots and their parts and components for research and development, completed the development of a complete set of demonstration and reproduction of industrial robot technology, developed a spraying, spot welding, arc welding and handling robots. 1986 National High-Tech Research and Development Program (863 Program) began to implement the theme of intelligent robots to track the world's robotics technology frontier, after several years of research, achieved a large number of scientific research results, and successfully developed a large number of robot technology, the development of robot technology. Scientific research results, successfully developed a number of special robots.
From the early 90's, China's national economy into the realization of two fundamental changes in the period, set off a new round of economic system reform and technological progress boom, China's industrial robots and a big step forward in practice, has developed a spot welding, arc welding, assembly, painting, cutting, handling, packaging and palletizing and other uses of industrial robots, and implementation of a number of robotic application projects. The formation of a number of robot industrialization base, for China's robotics industry has laid the foundation for the take-off.
China's industrial robots after? Seven Five? The program, the? Ninth Five-Year Plan? Tackling plan and 863 program support has made great progress, industrial robot market has matured, the application has been spread across all walks of life.
The focus of China's future industrial robotics development: First, dangerous, harsh environments, operating robots: mainly riot control, high-voltage charged cleaning, planet detection, oil and gas pipelines, and other robots; Second, medical robots: mainly brain surgery auxiliary robot, remote operation auxiliary orthopedic, etc.; Third, biomimetic robots: the main mobile robot, the network of remote-controlled operation of robots, etc.. The development trend is intelligent, low cost, high reliability and easy integration.
Second, the development trend of industrial robots
Robotics is a typical representative of advanced manufacturing technology and automation equipment, is a man-made machine? Ultimate? form. It involves machinery, electronics, automatic control, computers, artificial intelligence, sensors, communications and networks and other disciplines and fields, is a variety of high-tech development results of the comprehensive integration, so its development is closely related to the development of many disciplines. The development trend of today's industrial robots are: First, the performance of industrial robots continue to improve (high speed, high precision, high reliability, easy to operate and maintain), while the price of stand-alone machine continues to decline. Second, the mechanical structure to modular reconfigurable development. For example, the servo motor, reducer, detection system in the joint module of the three integration; there are joint module, rod module with the reorganization of the construction of the robot. Third, the industrial robot control system to PC-based open controller direction, to facilitate standardization, networking; device integration to improve the control cabinet is becoming increasingly compact, using a modular structure, greatly improving the reliability of the system, ease of operation and maintainability. Fourth, the role of sensors in the robot is increasingly important, in addition to the use of traditional position, speed, acceleration and other sensors, vision, force, acoustic, tactile and other multi-sensor fusion technology in the productized system has been a mature application. Fifth, robotized machinery began to rise. From 94 years the United States developed? Virtual axis machine tool? Since this new device has become one of the hot spots of international research, have to explore the development of its practical applications.
The overall trend is that the concept of robotics from the narrow concept to the broad concept of robotics transfer, from the industrial robotics industry to the solution business robotics industry development. The connotation of robotics technology has become a flexible application of robotics technology, with the actual action of the intelligent system. Robot structure is more and more dexterous, the control system is getting smaller and smaller, and its intelligence is getting higher and higher, and is moving towards the direction of integration.
Third, China's industrial robot development challenges and prospects
China's industrial base is thin, the development of industrial robots has been in a preliminary stage of development, although our country from the 70s of the last century began to research and development of industrial robots, but the lack of technological force and the technical blockade of the Western countries, for this, in the process of development, there are more problems. Breakdown, there are the following points:
First of all, China's basic parts manufacturing capacity is poor. Although our country has a certain foundation in the relevant parts, but whether from the quality, product series comprehensive, or batch supply with foreign countries there is a big gap. Especially in the high-performance AC servo motors and precision reducer gap is particularly obvious, thus resulting in the import of key components, affecting the price competitiveness of China's robots.
Second, China's robots have not formed their own brand. Although there have been a number of companies engaged in the development of robots, but have not formed a larger scale, the lack of market brand recognition, in the robot market has been facing the suppression of foreign robot brands. Foreign robots as a mature industry to reduce the price of the whole machine to attract domestic enterprises to buy, and in the follow-up of the maintenance of spare parts cost a lot of strategy, and gradually occupy the Chinese market.
Third, the understanding is not in place, in the encouragement of industrial robot products less policy. Industrial robot manufacturing and application level, on behalf of a country's manufacturing level, we must recognize the importance of the development of China's industrial robotics industry from a national height, which is China's transformation from a manufacturing power to a manufacturing power important means and ways. □

The development of network technology to the mechatronics equipment remote monitoring and remote control provides a convenient condition, therefore, the network technology and mechatronics technology will be combined with the focus of mechatronics technology development. In the production process, the operator needs to walk back and forth in the workshop, to master the state of the equipment, and the operation panel of the machine tool operation, through the establishment of communication protocols between the mechatronics equipment and the control terminal, and through the fiber optic and other media to achieve the transmission of information and data, you can realize the remote monitoring and operation, reduce the amount of labor of the workers, and a variety of control system functions are theoretically based on the network technology. is built on the basis of network technology.
2.3 Environmental protection.
In the development of human society in recent decades, although the economy has been rapid development, people's living standards have been significantly improved, but at the expense of resources and the environment at the expense of the development model so that human beings rely on the survival of the environment has been seriously polluted, therefore, in the strategy of sustainable development put forward today, the development of any technology should be environmentally friendly as a prerequisite, otherwise there is no future, so environmental protection is the machine. The future, so environmental protection is the inevitable trend of mechatronics technology development. In the application of mechatronics process, through the efficient use of resources, and in the manufacturing process to achieve standard emissions or even zero emissions, the product in the use of the process of ecological environment does not affect, even after the end of life can also be effectively recycled, which is the mechatronics technology environmentally friendly specific forms of expression, in line with the requirements of sustainable development.
2.4 Modularization.
Due to the large number of manufacturers of mechatronics devices, in order to reduce the cost of system upgrading and transformation, and provide convenience for maintenance, modularization will be a very promising research direction. Through the modularization of functional units, the corresponding functional modules can be directly assembled or replaced when the need to increase or change the function, even if there is a failure, only the damaged module can be replaced, the work efficiency is very high, and the enhancement of the generality of the enterprise saves a lot of cost.
2.5 Self-energized.
Mechatronics has higher requirements for power, if there is no adequate power supply will affect the production efficiency, and even due to power outages caused by data loss, etc. Therefore, through the equipment comes with a power energy system can always maintain an adequate supply of electricity, so that the system runs more smoothly.
3 Conclusion
In summary, the application of mechatronics technology can make the production efficiency and accuracy of the product greatly improved, in the current industrial production has a greater technological advantage, I believe that with the development of science and technology, the level of mechatronics technology will continue to improve, and make greater contributions to industrial production.
