News - More information about Welding Robot

Welding robot application technology is the fusion of robot technology, welding technology and system engineering technology. Whether welding robots can be applied in actual production and give full play to their advantages depends on the joint improvement of these technologies, and system engineering technology is robot technology. and adhesives for welding technology. At present, the welding process is becoming the mainstream process in industrial production at an alarming rate, and welding quality and welding productivity are issues that cannot be ignored by any enterprise, so the wide application of welding robots is imperative.

Features of Industrial robot

1. Flexibility

The robot is a CNC three-dimensional working machine with six degrees of freedom, which can not only realize the accessibility of the welding torch position, but also realize the angle change of the welding torch. Although its accuracy cannot be compared with traditional machine tools, for welding production, the repeatability of the robot has been completed to be competent

From the point of view of operation, the balance between purchase and output of equipment is very important for enterprises. In addition to the influence of the market, the replacement cycle of products is relatively shortened. If a special welding machine is used for welding production, it is difficult for the special welding machine to quickly adapt to the changes of the product when the product is changed, thus hindering the speed of the introduction of new products. This delay is very likely to seriously affect the rapid development of the enterprise. Using robots for welding production, enterprises only need to compile a new program to realize the production of new products, which enables enterprises to seize the opportunity in the market.

2. Man-machine dialogue

Human-machine dialogue means increased automation, which also brings us efficiency and benefits. Human-machine dialogue is the exchange of "command" and "sensing", and its development depends on the development of sensing technology. At present, more and more various sensors have been used on the welding robot workstation. For example, the tracking of the welding process can be realized by means of the current detection device; the detection of the position of the welding seam can be realized by using the visual sensor.

3. Application Features

motorcycles, construction machinery, furniture factories, shelves, hardware, shipbuilding, stoves, railway locomotives and other industries. Automobiles are the largest user and the earliest user of welding robots. Welding robots in automobile manufacturing and auto parts production enterprises account for 76% of all welding robots. In the automotive industry, the ratio of spot welding robots to arc welding robots is 3:2, while other industries are mostly arc welding robots.

(2) Since the 1990s, the introduction of advanced technology, production equipment and process equipment has rapidly improved my country's automobile manufacturing level to large-scale production, and foreign welding robots have entered China in large numbers.

(3) There is still a big gap between my country's welding equipment level, the manufacturing level of front and rear process equipment, and the system integration capability, which directly restricts the development of robots in other domestic industries.

(4) Everyone's understanding of the robot is far from enough. Some people have too high requirements for it, and one-sidedly believe that no matter what product, it can be welded. The quality of the robot used represents the manufacturing level of an enterprise. Therefore, the enterprise must improve the manufacturing level to meet the production requirements of robot welding.

Application Technology Analysis of Welding Robot

1. Common development of robots and welding equipment

The development of the past few generations of robots has been based on the development of welding equipment to complete a number of welding-specific functions, such as gradual adjustment of welding parameters, intermittent wire filling welding using weaving synchronization technology during TIG welding, and arc welding sensors (arc welding). Tracking) function and welding real-time monitoring function, etc., are developed under the demand of welding process.

Similarly, welding equipment manufacturers have also made many improvements in the design of welding power sources in order to realize robot automatic welding. For example, the robot can detect the high voltage used in the position of the welding seam, and the welding power source is built-in; the communication interface with the robot On the one hand, many welding machine manufacturers have adopted a convenient and fast communication interface.

2. Application of welding robot in improving production efficiency

(1) Improve accuracy and ensure high-speed welding

The application of robots in production means the pursuit of high efficiency and high welding quality. Therefore, all robot manufacturers are seeking breakthroughs in welding speed, and the high precision of robots in trajectory control is a reliable guarantee for high-speed welding.

(2) Dual-machine coordinated welding function

Sometimes we encounter long workpieces, and the welds are distributed at both ends of the workpiece. If one robot is used for welding, the welding deformation will be inconsistent due to the different welding of the two ends at the same time, so that the workpiece will be twisted and deformed in the length direction. It is difficult for the welded workpiece to meet the size requirements. For this type of workpiece, we often use two robots to coordinate welding at the same time, which promotes the two-robot dual-machine coordinated welding technology. This technology is often used in the welding of automobile rear axles and mufflers.

2 robots correspond to 1 positioner driven by the external axis of the robot. There are two mirror-symmetrical parts on the workpiece placed along the length of the positioner. Two similar girth welds require two robots on the positioner. Simultaneous and coordinated welding can be achieved while rotating, in this way, the efficiency of welding production can be doubled.
