What do you learn in robotics?
What aspects are involved in the study of industrial robot technology? Industrial automation programming, production, maintenance, debugging, maintenance, after-sales service, system integration, etc.
1. Industrial robot body
In order to train the industrial robot, we must first learn the industrial robot body, and understand the structure principle, motion principle and programming application of the industrial robot body.
If its program can be used flexibly, other robot systems can also be used naturally, with the same diameter. Secondly, we should be familiar with robot coordinate application, arc instruction, robot logic control statement application, robot processing, fault handling, industrial control PLC control robot trajectory, stop and system integration project programming.
When you learn the industrial robot ontology, you can roughly understand the use of the robot manipulator, programming operation, looking for a job, you can do industrial robot programming, through programming familiar with the basic and then enter the industrial robot debugging stage to become a real engineer. This is a foundation of industrial robot engineers. Hai Chi robot can be trained, manufacturers direct one-to-one training without collective training, one person and one robot, so that you can absolutely program and operate independently.
2. Electrical knowledge learning
Industrial robot needs the cooperation of programmable controller, and the programming of programmable controller has certain logic, which involves the application of frequency converter and servo motor.
Generally speaking, if we want to use industrial robots flexibly, we need the cooperation of peripherals and industrial robot programming. Robot workstations include: handling, welding, loading and unloading, spraying, palletizing and other applications. Learning electrical knowledge is to enable you to use non-standard equipment. Only by combining non-standard equipment and industrial robots can you be regarded as an engineer. This part can be trained to give you a certain understanding. But real use can only be learned in the installation and debugging of robots and overall equipment. For example, the clamp of the robot clamping things, the robot grasping after the conveying of the conveyor belt workpiece stops, the welding locator, the spraying turntable, etc.
What’s the point of using plc to control robots?
I’m glad to answer your question. I work in the automobile industry that uses plc to control robots, as you said, so I’ll answer you from here.
The robot has its own control system and programming language, and it can also form an independent network. Robots can also meet a variety of process requirements according to the installed tools, and the common one is robot welding. Robot grip. Robot stud welding, robot measurement and so on, among which there are high precision, repeatability, weight and positioning, which can be realized through the programming of programs and the cooperation of tools. The kcp of the robot can more intuitively view the robot trajectory, fault alarm, and monitor the quality and stability.
2 plc, different from robot positioning, robot pays attention to motion logic control, because it is mainly working. Plc pays attention to control, including communication control between master station and distributed station. Between the master station and the master station, but also with frequency conversion, private server drivers and other cooperation with the use of plc is equivalent to the brain, it is used with HMI. Can be more intuitive control and monitoring of all site signals, as well as action feedback.
(3) using plc to control the robot, not only the production line can be orderly, but also the robot can be monitored by HMI. Robot operation failure can also be better feedback through HMI, the robot sends the signal to plc,plc through signal processing to control the operation of the robot.
PLC is a logic controller. The industrial robot is composed of a controller and six servo drives to drive six servo motors (six-axis robot).
1. An assembly line in industry is composed of many robots, these robots are equivalent to human hands, and PLC is equivalent to human brain, sending control instructions to each robot and controlling the orderly and continuous operation of the whole production line. PLC controls robot motion is actually the result of signal interaction between PLC and each robot controller.
2. The robot has its own controller. If a single robot operates without external control signals, it does not need additional PLC control. In the actual project, each robot is only responsible for a task as an executive body, and generally needs to be connected to the external control system to receive external control signals to carry out the task.
If you want to learn about robots or need robot information, you can contact me.
Give me a brief personal opinion!
The robot is very powerful, it can repeatedly carry heavy objects, but also can maintain excellent position accuracy, many people can not do things, and can not adapt to the environment, it can be competent.
However, in an industrial automation production line, there are often many stations, and the tasks accomplished by each station are different, for example, there are 10 stations. If you only use one robot, install it with tracks and let it run, the time beat of such a production line is still very low, so on the production line, it is often the cooperation of multiple robot stations, and one robot is placed in each station. This is the actual requirement of industrial production and the result!
When many robots cooperate on a production line, it is necessary to have a better level of controller to control the action of each station and process relevant information, not only to tell the robot what to do, but also to record a lot of information about the assembled parts and the final result.
The robot action unit does not mean that the things assembled at this site are qualified, so plc uses vision or other inspection means to tell the robot which are qualified and which are not qualified, as well as the follow-up actions.
Therefore, even if the robot is not controlled by plc, a more advanced controller is needed to control the robot on the line so that they can better serve the production line!
I hope it’s of some help to you. Thank you.
This problem can be considered from two different applications: robot and PLC.
1.PLC, as an indispensable part of the industrial automation industry, has been known by more and more people, whether it is a simple workstation or a complex automatic production line, can not be separated from the shadow of PLC. It has stable operation and rich expansion functions. It can realize complex logic control and fast mathematical operation and other functions.
two。 As another part of automation, robot has its own control system, which controls the motion of the robot (linear motion, arc motion, point-to-point motion, etc.). At the same time, it can also carry out logical control and mathematical operation functions.
3. The above two points seem to have the same function, but there is a clear distinction in the application. The robot can run in a single workstation unit without PLC control. But for the complex automatic production line, the robot needs to coordinate with each other, and PLC is a good coordination tool at this time. It can coordinate the functions of motion interlock, security protection, data transmission and so on.
4. Through the PLC+HMI function, some operations of the robot can be placed on the HMI interface, so that workers who do not understand the operation of the robot can also start and run the robot.
The above are some of the significance of PLC control robot, if you have a better understanding, you can leave a message to discuss.
There seems to be no consistent definition of robot, which probably means a machine that can complete a certain workflow on its own, and people can interfere with its workflow and can be used to assist or even replace human beings to do some work and services. In this sense, the robot is also a kind of machine equipment, and PLC is the logic controller, it is natural to control the machine equipment. PLC itself is born and improved for machine control, please pay attention to: Rongji igniter
1. There are many automated machines in industry, all of which can automatically complete some automated production processes, and some can also be combined with other production equipment to form a more complex production process, so these automated devices can actually be understood as a huge robot. PLC acts as the “brain” in the operation of these devices, which can be said to be industrial control now. It is almost inseparable from PLC.
2. Robots currently mentioned in industry are more robotic arms, which can be used for welding, stacking and spraying. They generally have 4-6 degrees of freedom and can be simply understood as spatial positioning control of several motors in different directions. From this point of view, these robotic arms are actually no essentially different from traditional multi-axis machining centers. In general, machining centers use numerical control systems such as NC, which can be programmed and processed by G code instructions, and manipulators do the same.
3. NC CNC system, the core is multi-axis position loop synchronous control, which can complete complex curve interpolation. In fact, the present PLC, even if it is small, already has several axis straight line and arc interpolation functions, and some also have position loop closed-loop control. Many functions of PLC are being compatible with professional NC, and some simple manipulator controls can be completed using PLC, so the cost will be reduced a lot, and maintenance and use will be simple and straightforward.
4. Even the NC CNC system itself needs logic control, because the logic control generally uses the ladder diagram to become relatively simple, and PLC has the advantage of logic control, so many NC need PLC to cooperate to complete the logic control, such as the need to open the lubricating oil pump at a certain time, some limit switch alarm and so on. Of course, the NC system is also compatible with some PLC functions, it can be said that the two are merging with each other.
5. It can be understood that PLC is a soft relay circuit, which is very much in line with the thinking of electricians. Robots, such equipment and devices, are also inseparable from this circuit.
Plc control is not a robot, you are probably talking about the manipulator used for grasping, handling and other operations, its significance is to liberate people from simple repetitive work, and more efficient, can work 24 hours a day, compared with people it is also less likely to make mistakes, the original work of several people may only need one person, and this person is only responsible for maintenance and inspection equipment! This is the automation of the recent craze.
Plc control execution is good, simple and good maintenance, equipment versatility, our company is to use cloud AI- field visual acquisition control host-plc control execution equipment, very good super strong function
PLC is still not powerful enough.
It is logical sequence control, executing fixed process tasks. If you want to be highly automated, self-identification, judgment, decision execution, human-computer interaction, PLC can not be completed, need advanced algorithms and controllers.
Its data processing capacity and speed still can’t keep up.
Is there any difference between a robot and a manipulator?
According to ISO 8373, robot is defined as: position can be fixed or moved, automatic control and repeatability can be realized.
Programming, multi-purpose, and the position of the end operator should be programmable within 3 or more degrees of freedom
Industrial automation equipment. Here the degree of freedom refers to the axis that can move or rotate. According to its structure, industrial robot
The form and programming coordinate system are mainly classified as articulated robot, mobile robot, underwater vehicle and right angle.
Coordinate robots and so on. Classified into mobile robots, underwater vehicles and cleanliness according to their main functional features and applications.
Robots, Cartesian coordinate robots, welding robots, surgical robots and military robots.
As widely used in various industries, Cartesian robots are mainly based on linear motion axes.
The motion axis usually corresponds to the X axis, Y axis and Z axis in the Cartesian coordinate system. Generally, the X axis and Y axis are transported inward in the horizontal plane.
The moving axis, the Z axis is the upper and lower motion axis. In some applications, there is a rotation axis or a pendulum on the Z axis
A moving shaft and a rotating shaft. In the vast majority of cases, between the straight-line motion axes of Cartesian robots
The included angle is a right angle.
In fact, whether it is a robot or a manipulator is just a general term, and it needs to be subdivided. From the point of view of address alone, we cannot say that they are not the same thing at all, nor can we say that they are exactly the same thing. As far as terminal demand customers are concerned, sometimes some customers will call them the same product, and some customers who have more contact with them will be able to subdivide their own demand products.
I hope it helps you.
Which areas will be replaced by robots first in the future?
In the future, the following areas will be the first to be replaced by robots:
1. Telemarketer
Telemarketers are most likely to be replaced, because they keep repeating the same knowledge, even without the replacement of machines, such a monotonous, repetitive, boring and inefficient job will die out sooner or later, of course, it should be used in the right way. Smart telemarketing can’t bring malicious harassment to the public as it was revealed at the 3.15 party this year.
2. Customer service personnel
Siri has been born for so many years, artificial intelligence has long been able to replace artificial customer service in technology, and the rest is the problem of popularization. In the past two years, this kind of artificial intelligence customer service platform has gradually become a hot start-up project in the Internet industry, and the answer accuracy of some products is said to have reached 97%.
3. Content editors and hosts
In the era of content entrepreneurship, manuscript creation has come back to life, but the advent of artificial intelligence may replace human creation. For example, in September 2015, Tencent Finance launched the automated news writing AI intelligent robot, which completed the first report of its editorial career in one minute. Subsequently, Xinhua News Agency also launched the writing robot “Quick Pen Xiaoxin”. Another example is the artificial intelligence host on the CCTV network this year, and the artificial intelligence news anchor recently released by Xinhua News Agency.

The difference between semi-automatic welding and fully automatic welding
Fully automatic welding of semi-automatic welding: it is necessary to improve the level of welding mechanization and automation, such as program control and digital control of welding machine; develop a special welding machine for automation of the whole process from preparation procedure, welding to quality monitoring; in the automatic welding production line, popularizing and expanding the numerical control welding manipulator and welding robot can improve the welding production level and improve the welding hygiene and safety conditions.
(plastics) welding the fusion of two or more surfaces of a thermoplastic product into a whole by heating and pressing or other methods.
Automation adopts the technical measures of machines, equipment and instruments with automatic control, which can automatically adjust, detect and process, and automatically carry out operations according to the prescribed procedures or instructions. Its purpose is to increase output, improve quality, reduce cost and labor intensity, ensure production safety and so on. The degree of automation has become one of the important symbols to measure the level of scientific, technological and economic development in modern countries.
Modern automation technology mainly depends on computer control technology. Welding production automation is the development direction of welding structure production technology. Modern welding automation technology will develop intelligent welding equipment on the basis of high-performance microcomputer wave-controlled welding power source, develop flexible welding workstation and welding production line on the basis of existing welding robots, and finally realize welding computer integrated manufacturing system CIMS.
The development and application of microcomputer automatic control technology in welding equipment, such as numerical control welding power source, intelligent welding machine, automatic special welding machine and flexible welding robot workstation. The function of the microcomputer control system in all kinds of automatic welding and cutting equipment is not only to control the welding parameters, but also to automatically coordinate the action of each part of the complete set of welding equipment and realize unmanned operation, that is, to realize the numerical control, automation and intelligence of welding production. Microcomputer-controlled welding power source has become the main body of automatic special welding machine and the basis of intelligent welding equipment. Such as thyristor arc welding power source controlled by microcomputer, transistor arc welding power source, inverter arc welding power source, multi-function arc welding power source, pulse arc welding power source and so on. The IGBT inverter welding power source controlled by microcomputer is an ideal equipment to realize intelligent control.
Most of the numerical control special welding machines are automatic TIG welding machines, such as automatic pipe / pipe TIG welding machine, automatic pipe / plate TIG welding machine, automatic TIG welding machine and so on. In welding production, it is often necessary to design and manufacture automatic welding process equipment according to the characteristics of weldments, such as welding machine tools, welding centers, welding production lines and other complete sets of welding equipment, most of which can be combined with general welding power source, automatic welding machine head, wire feeding mechanism, welding car and so on, which can be coordinated into a whole by a programmable microcomputer control system.
