Robot is intelligent manufacturing? At present, many regions in China have put forward the machine replacement strategy to deal with the labor shortage. In addition, robots are the integrators of advanced manufacturing, artificial intelligence and other technologies. If a factory is equipped with a large number of robots, it seems to become the business card of a smart factory. For a time, China's robot market was hot

do Chinese manufacturing enterprises buy it? In fact, different enterprises have different account books in mind

each robot production line has its own advantages and disadvantages

there is no doubt that the robot production line is one of the transformation directions of the manufacturing industry. For Chinese manufacturing enterprises, are they equipped with robots? Different enterprises have different interpretations

XCMG is the leader in China's construction machinery industry. At present, XCMG is transforming its production base. The first is to replace all workers with welding robots on the welding line. The second is to realize the connection of machine tools. The input process parameters and production allocation previously operated by workers are omitted. The machine tool connection directly realizes the full automation of parameter adjustment, production scheduling and quality inspection. The third is to improve the distribution capacity through the combination of MES and supply chain system

xujianjian, assistant director of XCMG information intelligent manufacturing development department, cited the advantages that robots can bring to XCMG before the application equipment experiment: welding robots have short response time and fast action, and the welding speed is 60 ~ 120cm/min, which is much higher than manual welding of 40 ~ 60cm/min; The performance is stable and can be trouble free for 10 years; One robot can replace 2 to 4 industrial workers and so on. He told China Electronics News that China's construction machinery industry is facing the great challenge of changing to high-end, undertaking international advanced manufacturing and participating in international division of labor. It is the general trend to replace people with machines. There are advantages and disadvantages for robots to replace human beings, but in general, the advantages outweigh the disadvantages

on the other hand, as a leading enterprise in China's equipment manufacturing industry, Sany Heavy Industry is cautious about the replacement of robots. Zhouzhijun, deputy director of Sany process information department, told China Electronics News that Sany has adopted welding robots on the welding line. However, on the general assembly line, due to the large number of parts and complex processes, there are many customized parts (source: stainless steel), which are irregular and small batch production, so it is not suitable for robot production and assembly. He disclosed that compared with the automobile factory, the monthly production volume of a model of Sany Heavy Industry is about dozens to hundreds, and the batch is relatively small

the advantage of replacing people with machines is to save manpower. Zhouzhijun frankly said that the unsaturated workload and the flow of industrial workers do have some impact on Sany. Sany has also considered replacing people with machines. As for the fact that it has not been implemented in a large scale, it is also out of concern about the input-output ratio

at the same time, zhouzhijun also pointed out that Xugong Group, an enterprise of the same type as Sany Heavy Industry, currently uses robots mainly in the welding process

robot factory is not a sign of intelligent manufacturing.

the transformation of old production lines by enterprises and the introduction of robots is a manifestation of the improvement of enterprise automation and intelligence. Is the robot production line a sign of the realization of intelligent manufacturing by enterprises or factories? Not really

dingdeyu, general manager and technical director of Yuangong International Technology Co., Ltd., said frankly in an interview with China Electronics News that the robot production line is an important technical means to improve labor productivity, product quality and stability, and is also regarded as an important symbol for enterprises to implement intelligent manufacturing, but it is not the only symbol or milestone. To implement intelligent manufacturing, enterprises can start from the aspects of intelligent products, mass customization, service transformation and smart factories, and should choose breakthrough points according to their own conditions

in addition, dingdeyu also said that the content of the smart factory includes not only the robot production line, but also the CPS (information physical system) that is fully controlled and accurately executed and the MES that is scientifically commanded. CPS emphasizes man-machine and material integration and unified command. MES emphasizes management improvement from three dimensions: Manufacturing Execution (i.e. vertical integration of industry 4.0), supply chain (i.e. horizontal integration of industry 4.0) and design process (i.e. design integration of industry 4.0)

yegenping, CIO of Zhejiang Sanhua, expressed his views to China electronic news. He believes that it is very necessary to introduce robots to replace traditional equipment or manual operation in some manufacturing sites and process links, but the most critical factor in the transformation and upgrading of traditional manufacturing industry is not the upgrading of hardware, but the upgrading and optimization of software, that is, business management. Because the wide application of robots requires that enterprises have achieved product standardization, process and tooling standardization, and equipment automation, many of which belong to the improvement of soft management. For many traditional manufacturing industries, robots can not replace labor at present, or the proportion of replacing labor is very small

at present, the situation of Zhejiang Sanhua is that the robot application is still in its infancy, and the number and scope of applications are limited. Sanhua has a pragmatic tradition and will not follow the trend to join the robot project. Yegenping said

dingdeyu pointed out that continuous improvement with the help of intelligent manufacturing concepts and methods is the most effective way of intelligent manufacturing and the correct path of intelligent manufacturing

robot application depends on the specific situation, and the workspace is also large.

the cost of a robot production line is as high as hundreds of millions of yuan, which is not a small cost for China's manufacturing plants. In particular, it is very difficult to invest a large amount of money in the transformation of the production line under the environment that 239 people are on board in recent years, the export of the manufacturing industry is blocked and the profit margin is still declining

one-step robot is not realistic. It needs to distinguish the situation and implement it step by step. Dingdeyu said that with the increase of output and the strict pursuit of quality, enterprises need to gradually improve manual work into an automated way. In order to improve automation, we should first select the bottleneck links of production capacity and quality, which may not be achieved in one step. Other industrial automation means with lower cost can be considered. For the links that are not suitable for automation improvement from the perspective of cost-effectiveness or technology, it can be considered to reduce errors and improve the quality through foolproof and error prevention, and improve the production efficiency of manual work through tool improvement

jiangmingwei, chief expert of Beijing Institute of automation, told China electronic news that the first places to use robots are those types of work with high labor intensity, poor production environment, prominent production safety problems and low production efficiency, such as riveting, casting and forging, explosive production, dangerous goods production, frequent heavy load handling and batch assembly. When using or not using robots, the investment benefit analysis must be carried out

jiangmingwei gave an example. More than 20 years ago, a 863/cims demonstration enterprise blindly pursued manufacturing automation, borrowed a large amount of money from the bank and carried heavy liabilities. The enterprise never recovered. This is a painful lesson

moreover, robots today do not have artificial intelligence. Jiangmingwei also pointed out that general industrial robots can only work in accordance with the procedures prescribed by people. No matter what changes in external conditions, they cannot make corresponding adjustments to the procedures, that is, to the work they do. If you want to change the work done by the robot, you must also make corresponding changes to the program. However, there are not many high-level skilled workers who can program and operate industrial robots. When enterprises are equipped with robots, they have to train this type of workers, which is undoubtedly another expenditure

if an enterprise wants to improve the level of intelligent manufacturing, jiangmingwei gives the suggestion that it should carry out long-term planning according to the principle of overall planning, step-by-step implementation, key breakthrough and benefit first, grasp the main line of the core competitiveness of the enterprise's sustainable development, and also need to carry out investment benefit analysis
