Looking at the world, the third wave of industrial revolution with "digital intelligent manufacturing" as its core has arrived, and the protagonist of this revolution is industrial robots. In the context of the weakening of China's demographic dividend, China's industrialization must create new competitiveness, and the application of robots on production lines will increase. Some experts predict that Chinese industrial robots will usher in a blowout development within a few years instead of simple linear growth.

According to the International Federation of Robotics, China will become the world's largest consumer of industrial robots by 2014. By 2015, China robot market demand will reach 35,000 units, accounting for 16.9% of the global total, becoming the largest robot market. Experts said the next three-year compound growth rate of China's industrial robot market up to 30%.

In the transformation process of emerging industries and traditional industries, robots play the role of “catalyst”. In the Construction Machinery industry, robots are often engaged in work spot welding, arc welding, painting, assembly production line, not only to ensure the stability of product quality, improve labor productivity, but also to improve working conditions and labor intensity. In recent years, China's construction machinery industry usher in rapid development in urgent need of upgrading and transformation, companies want to grab a larger market share in the fierce competition to get rid of the homogenization of competitive products, the need to strengthen the level of automation of production lines, to introduce robots will not be Or missing.

Although faced with the major companies in the throes of transformation and upgrading, but many have the strength, the enterprise has a long-term vision has been to find a new way in the throes of this. As a leading domestic large-scale construction machinery manufacturer and a leading enterprise in the bulldozer industry, Shantui should be said to be at the forefront of domestic counterparts in the application of automated welding equipment. It began to apply welding robots and automated welding machines in the mid-1990s. These initiatives not only so that their production has been effectively improve efficiency, but also changed the traditional concept of staff.

The benefits of the introduction of robots can also be seen in the rapid development of Sany Heavy Machinery. In 2007, two robots appeared in the Sany Heavy Machinery production line. Since then, corporate sales have grown by leaps and bounds, and the robotics team has grown. In the Sany Heavy Machinery Lingang Industrial Park, which was put into production not long ago, it is possible to see more than 200 robots performing their duties, busy cutting, welding, painting or gluing, all of which are based on one Good hand.

At the end of 2012, the production system of weld welding robot in the Mixer drum was officially launched in Zoomlion Industrial Park, which is the first time in the domestic concrete machinery industry.

Although there has been no shortage of people who eat crabs, the industry has been around for a long time. While seeing the advanced automation level of the automobile production line, we have seen that the production line of construction machinery is still dominated by labor, and the level of self-development is weak.

This has nothing to do with the characteristics of engineering machinery products. The parts are self-contained, the structure is complex, the welding quality is high, the workload is huge, and the varieties and models are numerous, which restricts the development of the automation level of the construction machinery production line. Secondly, due to the complexity and precision of the robot construction, it puts high demands on the maintenance personnel, sometimes it needs the assistance of the manufacturer, and also puts forward higher requirements for the quality of the workers who operate the robot. Teaching programming, troubleshooting, etc. are required. Certain professional knowledge. In addition, the original welding robots are imported, the accessories are not easy to prepare, and the cost of use is high. Automation requires efficiency, not just speed. When the robot was first applied, many companies also took some detours, and the flexibility of the robot was not fully utilized. According to the survey, some enterprises have introduced arc welding robots. For various reasons, there are still some states that are under load or unable to operate normally, which directly affects the confidence of more enterprises in using robots.

The production line of construction machinery is a big direction towards automation, flexibility and intelligent development. The application of robots will inject new vitality into the development of the industry. Since there are key support policies for the national “Twelfth Five-Year Plan”, it is believed that the “counterattack” of construction machinery production line robots is just around the corner.
