In the production workshop, the mechanical arms work together to complete complex and precise production processes; Unmanned transport vehicles shuttle between them, and accelerate the integration of digital technologies such as the Internet of Things and big data with the manufacturing industry, so as to accelerate the digital and intelligent transformation of the traditional manufacturing industry. Experts believe that relevant enterprises should seize the opportunity to promote "Made in China" to high-quality development through continuous innovation. "Manipulators" play a major role in the Glory Intelligent Manufacturing Industrial Park in Shenzhen, Guangdong Province. A precise screen assembly is in progress - bone conductive materials with an accuracy of up to 1/7 of the diameter of a hair are automatically attached to the super curved flexible screen by the manipulator under the "gaze" of high-precision multi camera. "Through machine vision recognition and algorithm logic optimization, we have achieved high-precision precision mounting." Song Yiwen, head of the Supply Chain Management Department of Glory Terminal Co., Ltd., introduced that with the support of big data and other technical means, the system can also conduct intelligent early warning on the production process to ensure the consistency of product quality. Intelligent manufacturing requires flexible and powerful "manipulators" to perform tasks, and more importantly, efficient "industrial brains" to be responsible for the overall coordination of all work. In the digital workshop, the intelligent management system can collect various key production information in real time, and conduct status assessment and problem diagnosis for the production process based on the data information, so as to provide scientific basis for managers' business decisions and help enterprises achieve digital operation management. Precision technology, smart management, and innovation and change inside and outside the enterprise's production workshops are a microcosm of the accelerated transformation and upgrading of China's manufacturing industry. At present, China has built more than 700 digital workshops, intelligent factories, industrial robots, 3D printing equipment and other intelligent manufacturing related equipment industries. The scale of manufacturing enterprises has been growing significantly. "Without the strong support of digital and intelligent technology, the quality, efficiency and core competitiveness of manufacturing can hardly be greatly improved." Wu An, director of the Institute of Industrial Economics of the Chongqing Academy of Social Sciences, believes that manufacturing enterprises should adhere to the direction of intelligent development, constantly promote intelligent transformation and upgrading through technological innovation and industrial innovation, and make intelligent manufacturing a new business card of China's manufacturing industry. With the accelerated development of intelligent manufacturing, a series of new models and new forms of business are also emerging. Among them, the application of digital twin technology in digital workshop, intelligent factory design and construction, upgrading and transformation, operation and maintenance, etc. deserves attention. The so-called "digital twin factory" refers to the digital model that digitizes the factory design scheme, production status and other information, applies modeling and simulation, multi model fusion and other technologies, and finally presents in a virtual form. With VR and other equipment, users can "see" the factory after its completion in advance, and its details are consistent with the actual factory, like twins. Zhang Jian, Chairman of Shenyang Innovation Design Research Institute Co., Ltd., has participated in the design and construction of several digital twin factories. He said that the Digital Twin Factory is not a simple visual animation, but the best plan given by engineers after repeated verification and calculation of big data. "Use
