] in recent years, Germany took the lead in proposing the concept of "industry 4.0", the United States implemented the "advanced manufacturing partnership" plan, Japan implemented the "smart manufacturing system", and China also proposed the "made in China 2025 plan". These all point to the same goal, that is, to promote the innovation of manufacturing industry through advanced it and automation technology, so as to achieve "intelligence", improve efficiency and reduce costs. To achieve this goal is an indispensable part

1. Development background of industrial robots

from 1920, the word "robot" was created by the author of the Czech drama microcomputer controlled electronic experimental machine, which is your better choice. Up to now, robots have developed for nearly a century, from the initial industrial robots simply used for handling, to the second generation industrial robots with vision and information processing technology, and then to the "intelligent robots" currently under research, The development and application of industrial robots are changing with each passing day

2. Application scenarios of industrial robots

in just over 50 years, robot technology has developed rapidly. Among many manufacturing fields, the most widely used field of industrial robots is the automobile and auto parts manufacturing industry, and is constantly expanding to other fields, such as mechanical processing industry, electronic and electrical industry, rubber and plastic industry, industry, wood and furniture manufacturing industry

in industrial production, welding robots, grinding and polishing robots, welding robots, laser processing robots, spraying robots, handling robots, vacuum robots and other industrial robots have been widely used

(1) grinding and polishing robot

grinding and polishing robot is mainly used for the grinding and polishing of aviation, marine and nuclear power blades. The robot holds the sand belt to grind and polish on the blade surface, and the flexible contact and visual positioning methods are used to reduce the grinding and polishing defects

compared with manual grinding and polishing, it has the characteristics of short processing time, high profile accuracy, small surface roughness and good processing consistency. It can adapt to heavy load and harsh working environment. High accuracy is required

(generally, it can be added to the two-thirds position of the fuel tank window) welding robot

arc welding robot is mainly used in the welding production of various auto parts, mainly including melting electrode welding and non melting electrode welding

in this field, international large-scale industrial robot manufacturing enterprises mainly provide unit products to complete equipment suppliers. Application features: it requires fast and stable movement and high positioning accuracy

(3) laser processing robot

laser processing robot applies robot technology to laser processing, and realizes more flexible laser processing operations through high-precision industrial robots

through the automatic detection of the machined workpiece, the model of the machined part is generated, and then the machining curve is generated. It can also be processed directly by using CAD data. It can be used for laser surface treatment, drilling, welding and mold repair of workpieces. High accuracy is required

(4) vacuum robot

vacuum robot is a robot that works in a vacuum environment. It is mainly used in the semiconductor industry to realize the transmission of wafers in the vacuum chamber

vacuum manipulator is difficult to import, limited, used in large quantities, and has strong versatility. It has become a key component that restricts the R & D Progress of the complete semiconductor equipment and the competitiveness of the complete product. High accuracy is required

(5) painting robot

painting robot is generally driven by hydraulic pressure, which has the characteristics of fast action speed, good explosion-proof performance and so on. Teaching can be achieved through hand-held teaching or point position teaching

painting robots are widely used in process production departments such as automobiles, instruments, electrical appliances, enamels, etc. The working environment of the spraying robot is poor, and its accuracy requirements are low

(6) handling robot

handling robot is controlled by computer and has the functions of mobile, automatic navigation, multi-sensor control, network interaction and so on. It can be widely used in flexible handling, transmission and other functions in various industries, as well as automated three-dimensional warehouse, flexible processing system and flexible assembly system

at the same time, it can be used as a means of transportation in the sorting of goods in stations, airports and post offices. It has large load and no strict accuracy requirements

3. Classification of industrial robots

industrial robots can be divided into the following types according to different methods: see the following figure for details

4. All customers who are just beginning to understand the mechanical experimental machine should pay attention to the human performance evaluation index

the basic parameters and performance indexes that represent the characteristics of the robot mainly include workspace, degree of freedom, payload, motion accuracy, motion characteristics, dynamic characteristics, etc

performance evaluation index of industrial robots

(1) work space

work space refers to the space that a specific part of the robot arm can reach under certain conditions. When bought back, it cannot be set up for experiment. The character and size of workspace reflect the working ability of robot

(2) degree of freedom of motion

degree of freedom of motion refers to the number of variables required by the robot operator to move in space, which is a parameter used to express the flexibility of robot action. It is generally expressed by the number of independent motions moving along and rotating around the axis

a free object has six degrees of freedom in space (three rotational degrees of freedom and three moving degrees of freedom). Industrial robots are often an open linkage system, and each joint kinematic pair has only one degree of freedom, so the number of degrees of freedom of robots is usually equal to the number of joints. The more degrees of freedom a robot has, the stronger its function will be

(3) payload

payload refers to the weight of objects that may be carried or the force or torque that can be borne by the arm end of the robot operator during operation, which is used to indicate the load capacity of the operator

when the robot is in different positions and postures, the allowable maximum transportable mass is different, so the rated transportable mass of the robot refers to the maximum mass that the wrist joint end can handle when the arm is in any position and posture in the workspace

(4) accuracy

the accuracy of robot mechanical system mainly involves pose accuracy, repeated pose accuracy, Trajectory Accuracy, repeated Trajectory Accuracy, etc

pose accuracy refers to the deviation between the commanded pose and the real pose center when approaching the commanded pose from the same direction. The accuracy of repeated pose refers to the inconsistency of the real pose after repeated response to the same command pose from the same direction for N times

Trajectory Accuracy refers to the proximity of the robot mechanical interface to follow the command trajectory n times from the same direction. The accuracy of trajectory repetition refers to the inconsistency between tracks after following a given trajectory n times in the same direction

(5) motion characteristics (sped)

speed and acceleration are the main indicators of robot motion characteristics. In the robot manual, the maximum stable speed of the main degrees of freedom is usually provided, but in practical application, it is not enough to consider the maximum stable speed only, and attention should also be paid to its maximum allowable acceleration

(6) dynamic characteristics

dynamic characteristics structural dynamic parameters mainly include mass, moment of inertia, stiffness, damping coefficient, natural frequency and vibration mode

5. An all-round interpretation of industrial robots

(1) the current situation of industrial robots in China

the reason why industrial robots can suddenly rise in the Chinese market:

first of all, in terms of cost, robots are usually only one fourth of the labor cost

secondly, robots can bring many new added values in terms of quality, efficiency, management, etc

therefore, China's industrial robot industry is in a blowout era under the combined effect of the rapid improvement of robot technology, the sharp decline in prices, the shortage of labor, the rise in labor costs and other factors

(2) key technology of industrial robot

industrial robot is composed of 3 parts and 6 subsystems. Most of them are mechanical part, sensing part and control part. The six subsystems can be divided into mechanical structure system, driving system, sensing system, robot environment interaction system, human-computer interaction system and control system

the key basic components of the robot are mainly divided into the following three parts: high-precision reducer, high-performance AC/DC servo motor and driver, high-performance controller, etc. The performance indicators of the robot mainly include workspace, degree of freedom, payload, motion accuracy, motion characteristics, dynamic characteristics and so on

(3) technical challenges faced by industrial robots

although robot technology has made great progress in recent years, we should clearly see the great challenges faced by the development of China's industrial robot industry

because key parts are monopolized by foreign technology, domestic robots do not have significant cost advantages. At the same time, a large number of robot manufacturers have the risk of low-end locking. In addition, there is a lack of effective connection between robot R & D, manufacturing and application.
