Introduction to welding robots for welding robots

Introduction to Welding Robots.

Welding robots are industrial robots engaged in welding, including cutting and spraying. According to the International Organization for Standardization (ISO) definition of an industrial robot as a standard welding robot, an industrial robot is a multi-purpose, reprogrammable automatic control manipulator (manipulator) with three or more programmable axes and is used in the field of industrial automation. In order to adapt to different uses, the mechanical interface of the last axis of the robot, usually a connecting flange, can be connected to different tools or end-effectors.

The welding robot is equipped with welding tongs or welding (cutting) guns on the flange of the end axis of the industrial robot, so that it can be welded, cut or thermally sprayed.

Classification of welding robots.

According to different standard classification, it can be divided into a variety of types, and according to the welding process, it can be divided into spot welding robots, arc welding robots, laser welding robots, etc.; According to the performance and technical parameters, it can be divided into super large welding robots, large welding robots, medium welding robots and small welding robots.

Application of welding robots.

Welding robots are widely used, such as: electronic connectors, computer data cables, automobile welding, small electronic components, etc. Next, Wuxi Jinhongying, an industrial robot integrator, will introduce in detail the application of welding robots in the four major fields of machinery manufacturing, automobiles and parts, electronic equipment and aerospace.

Advantages of welding robots.

It is not difficult for us to find that in many modern production workshops, there are welding robots, welding robots have intelligent control systems, with stable welding quality, improve welding efficiency, and realize the advantages of intelligent filling of welds.

If you are interested in welding robots, you can contact Golden Red Eagle.

With the development of electronic technology, computer technology, numerical control and robotics, automatic welding robots, since the 60s began to be used in production, its technology has become increasingly mature, mainly has the following advantages:

1) Stabilize and improve welding quality;

2) improve labor productivity;

3) Improve the labor intensity of workers and work in harmful environments;

4) reduce the requirements for workers' operation technology;

5) It shortens the preparation cycle for product modification and replacement, and reduces the corresponding equipment investment.

Therefore, it has been widely used in all walks of life.

A big name and a small name, different names for the same thing. It's called a robot because it has a brain (CPU) in addition to its arms; It's called a robotic arm because it looks like an arm and performs the same function as a hand. The factories I came into contact with use European and American standards, which I like to call robots, and Japanese, which I like to call robotic arms.

It's a thing, it's just called differently, some people are used to calling it a welding robot, and some people are used to saying a welding manipulator.

The welding robot is an automatic mechanical equipment used for welding operations, which is to install welding tongs or welding (cutting) guns on the flange of the final axis of the industrial robot, so that it can be welded, cut or thermally sprayed. The welding work is completed through the teaching programming, and the welding production can be automated.

Generally, according to the shielding gas used by the welding robot to distinguish the types of robots, there are two common types, one is the welding robot that uses carbon dioxide as the shielding gas, which is called carbon dioxide gas shielded welding robot, referred to as gas shielded welding robot;

Gas shielded welding robot.

The other is a robot that uses argon as a shielding gas, called an argon arc welding robot.

TIG welding robot.

A welding robot refers to a robot that specializes in welding work. In terms of classification, spot welding robots, arc welding robots, laser welding robots, etc. are classified according to the welding process, and spot welding robots and continuous welding robots are classified according to the welding method. The structure of the basic welding robot is similar, you can adjust it by changing the external welding gun, flux core, internal become, etc., if you buy a welding robot, you can find Bronte this manufacturer to see, their welding robot is widely used, the quality of the welding robot provided is also relatively stable, and it is not easy to have quality problems in the process of use.

Welding robot is a modern and automated equipment that integrates computer, electronics, sensors, artificial intelligence and other aspects of knowledge. The welding robot is mainly composed of two parts: the robot body and the automatic welding equipment. The welding robot is easy to achieve the stability and improvement of welding products, can achieve 24-hour continuous production, greatly improve production efficiency, and replace manual work in harmful environments for a long time.

Welding robots directly used for welding include arc welding, resistance welding, and gas welding.

First, the components of the welding robot.

1. Execution part: This is a mechanical structure in which the welding robot transmits force or torque and performs specific actions to complete the welding task. Including the body, arms, wrists, hands, etc. of the welding robot.

2. Control part: responsible for controlling the electronic and electrical components and computer systems of the mechanical structure to complete the welding operation between the specified positions according to the specified procedures and the required trajectory.

3. Power source and transmission part: it can provide and transmit mechanical energy for the execution part of the components and devices, and the power source is mostly electric or hydraulic.

4. Process guarantee part: mainly including robot welding power supply, wire feeding, gas supply device, etc.

Second, the degree of freedom of the welding robot to choose.

The arms and wrists of the welding robot are the basic parts of the movement. The robot arm of any design has three degrees of freedom to ensure that the end of the arm can reach any point in its working range. The three degrees of freedom of the wrist are the rotational motion of the three axes x, y, and z that are perpendicular to each other in space, and are often called roll, pitch, and deflection motion.

With the development of electronic technology, computer technology, numerical control and robotics, automatic welding robots, since the 60s began to be used in production, its technology has become increasingly mature, mainly has the following advantages:

1) Stabilize and improve welding quality;

2) improve labor productivity;

3) Improve the labor intensity of workers and work in harmful environments;

4) reduce the requirements for workers' operation technology;

5) It shortens the preparation cycle for product modification and replacement, and reduces the corresponding equipment investment.

Therefore, it has been widely used in all walks of life.

In order to complete the welding operation, the welding robot must rely on the support and cooperation of the control system and auxiliary equipment. The complete welding robot system is generally composed of a robot operator, a positioner, a controller, a control system, a welding sensor, a control computer and corresponding safety equipment.

The welding robot is to complete the welding work through the teaching programming, the teaching programming is completed gradually, the operator sets the key points of the weld trajectory and the welding parameters in the teaching pendant, the welding parameters mainly include the welding current, welding voltage, welding speed, wire feeding speed, welding gun posture, swing amplitude, etc., the industrial welding robot can remember the operator's operation, and automatically generate a program that continuously performs the operation.

After generating programming, it is necessary to complete a teaching operation first, observe whether the movement trajectory of the industrial welding robot is deviated, and then carry out a test welding operation, the operator adjusts the welding parameters according to the welding quality, and after completing the teaching, only need to give the industrial welding robot a start command to carry out accurate welding.

When starting the industrial welding robot, it is necessary to carry out the operation process, which can reduce the incidence of misoperation, and in the event of misoperation, the intelligent welding system will stop the work and play a protective role.

**Control computers play an important role in welding work. Connected with the welding robot controller through the serial interface, the control computer is mainly used to form a communication network between computers at the same level or different levels, and at the same time cooperate with the sensing system to realize the offline programming of welding paths and parameters, the application of the welder system and the management of production data.

The welding robot realizes automatic welding production, thanks to the cooperation and role of each component, which can stabilize the welding quality, improve the welding efficiency, and clarify the production cycle of the product in the welding work.

Welding industrial robots automate the welding process to improve accuracy, enhance safety, and reduce the time it takes to complete each project. This advantage makes the automated welding process of welding industrial robots a popular alternative to manual metal joining. Some industries utilize this automated process to get the desired results as quickly as possible.

Welding industrial robots are mainly used in industries that require high productivity. Usually, spot welding and arc welding can be carried out with the help of robots. In addition to resistance spot welding and arc welding processes, two common welding processes used for production purposes are metal inert gas (MIG) welding and tungsten inert gas (TIG) welding.

As follows:

5. Kuka

KUKA Robotics is one of the oldest robotics companies in Germany. In 1973, KUKA manufactured the world's first six-axis electromechanically driven industrial robot, Famulus. In 1976, the IR6 60 was invented, a new robot type, a six-axis electromechanical drive with angular hands.

Welding robots have the characteristics of high production efficiency, stability and flexibility, and their performance is particularly prominent in the field of industrial production. It is mainly composed of the following aspects:

First, the wrist, which is the main part of various welding work, just like the human wrist, is very flexible and can complete various complex and precise welding work;

second, the arm, which is an important connection between the wrist and the fuselage, and the arm length can be flexibly adjusted to cope with different operating spaces;

Third, the machine base, has a supporting role, and to ensure the stability of the robot when working, in the manufacturing industry, there are stationary robots and mobile robots, the period is mainly that the former base is fixed on the ground and the latter base can move at will.

Compared with manual work, welding robots have the advantages of stable working state, high work efficiency and low working environment requirements. Because the working state of the robot is relatively stable, the welding quality can be effectively guaranteed, before running the welding robot, as long as the content of the work and the trajectory of the weld are planned, it can be guaranteed to work stably in the state of uninterrupted power. Robots replace workers, which can reduce the number of workers working in poor working conditions, and can also ensure that they can still maintain a stable working condition under the condition that workers cannot work normally.

Finally, unlike a worker's limited working hours per day, the robot can run 24 hours a day, which greatly increases productivity.

While welding robots have several advantages, they also have some disadvantages and challenges:

First, before the operation of the welding robot, if the welding parameters are not selected properly, the weldment may be defective, resulting in an increase in the weldment scrap rate.

Second, the investment is large and the cycle is longer.

The Yizhi intelligent automatic welding robot that I understand can be classified according to its functions, such as cutting, welding, handling, spraying, palletizing, etc., as well as its arm span, load, etc.

A welding robot, in the vernacular, is a robotic arm with a welding torch in its arms. Instead of manual welding.

Robots are used in the field of welding, that is, welding robots.

Robots are called differently depending on how they are classified.

Classification according to structure: Cartesian coordinate robots, multi-joint robots, parallel robots, etc. are classified according to application occasions: welding robots, spraying robots, palletizing robots, etc.

Welding robots: industrial robots engaged in welding.
