What is the relationship between PLC and industrial robots?

First of all, industrial robots are not the robots we usually see in movies. In fact, most of them have no feet. Such as manipulators, many use servo motors and stepper motors as motor nerves. Plc controls the robot by controlling these motors. The following answer is transferred to Zhang Huajun.

Some engineers who are good at robot programming use PLC as the IO module of the robot to communicate through the bus.

Some engineers who are good at PLC programming use robots as action actuators.

Because all the powerful robots have their own robot operating system and programming language, so the program development of the robot is completed in the software platform provided by the manufacturer, so it is necessary to communicate with PLC. In fact, programming at both ends is not very scientific.

If you use a PLC (or multi-axis motion controller) that supports multi-axis motion interpolation, you can develop arm motion and PLC logic in one hardware, which is very convenient, but the problem is that you have to make your own robot body, which has no credit-to-price ratio.

So the best solution is to find a mature robot brand arm body, with support for multi-axis interpolation PLC directly to drive!

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.

What is the relationship between Industrial Robot and Automation and plc programming

Relationship: an industrial robot is a device that executes commands; PLC can coordinate and control these devices; and automation is made up of multiple such devices and PLC.

The most important feature of the industrial robot is that it can work according to the pre-set standard workflow, while PLC operates the electronic system for digital operations with a variety of man-machine interfaces, while automation includes two characteristics: the expected goal and the special computer system.

PLC can complete the technical requirements of industrial robots, but industrial robots can not achieve the comprehensiveness of PLC, that is to say, industrial robots belong to a branch of PLC, and then refine and make a special development environment for robot automation, so that developers can save a lot of development time and get some mandatory security measures at the same time.

Industrial robots are performed by many motors. In fact, the essence of controlling industrial robots is to control those motors to turn forward, reverse, rotate faster, or turn strong points.

Extended data:

Automation is a general term for machinery, equipment or production process to achieve measurement, manipulation and other information processing and process control according to the expected goal without direct manual intervention. The “embedded system”, which is widely used in the manufacturing industry, completely embeds mechanical or electrical components into the controlled devices, and is a special computer system designed for specific applications.

Industrial robot is a kind of multi-joint manipulator or multi-degree-of-freedom manipulator, which is a kind of mechanical device that works by control system and its own power, which is often used in industrial production. An industrial robot can replace the multi-person labor force and work in accordance with the previously established standard workflow, helping to reduce the related defective rate and increase unit output.

PLC, also known as programmable logic controller, is a kind of digital operation electronic system with high utilization rate in modern industry. There are a variety of man-machine interface units and communication units on the PLC, which control the production of the equipment through digital or analog input and output.

Its working principle can be divided into three stages: input sampling, program execution, output refresh, and then re-input sampling, execution and output reciprocating (or cyclic) work.

Can plc be used for robot joint control?

Yes, PLC can be used for robot joint control. In fact, in modern industrial robots, PLC is usually used to control the joint motion of the robot. As a general control device, PLC can easily integrate a variety of sensors and actuators, such as encoders, motors, hydraulic / pneumatic actuators, etc., to achieve synchronous and accurate joint control. The programming of the PLC controller is usually based on the sandbox programming environment, and the joint motion of the robot can be synchronized by different actuators according to the preset trajectory, so as to realize the control of the robot.
