“We will further leverage the leveraging role of fiscal interest subsidies, incentive and subsidy funds, industrial guidance funds, etc. to drive increased investment in bank credit, social capital, etc., provide more support for industrial machine research and development, public supporting facilities, etc., and reduce the cost of enterprise innovation. Actively promote the industrial mother machine industry to continuously move towards high-end.” said the relevant person in charge of Wuhan Municipal Economic and Information Technology Bureau.
Chongqing Yongchuan——
Leading enterprises take the lead and seek intelligent upgrades
Welding spattered and flames shot out. In the welding workshop of Great Wall Motors’ Chongqing Yongchuan factory, intelligent handling robots loading materials shuttle back and forth. The orange-yellow welding robot flexibly flips its mechanical arm to accurately weld auto parts… Walking through the entire workshop, in addition to checking parameters in front of the screen engineers, not many staff members can be seen.
“There are 442 robotic arms in the welding workshop, with 2 to 4 robotic arms assigned to each workstation. A maximum of 8 robotic arms can cooperate with each other at one workstation.” Zhang Wenjun, director of the equipment and power department of Great Wall Motors Chongqing Branch, said, “The Yongchuan factory has been operating since 2019. Since it was completed and put into operation in 2017, we have continued to promote the intelligent upgrading of the entire factory and promoted the quality and efficiency of the production line.”
Behind the efficient cooperation of robots is a precise quality control system. “During the welding process, the self-correction control system can monitor and adjust welding parameters such as pressure, current, and time in real time, making the quality more stable than manual welding,” Zhang Wenjun said.
In order to ensure product quality, the Yongchuan factory has achieved full coverage of machine vision inspection for the glue coating process throughout the entire production process. During the gluing process, a customized multi-camera monitors the gluing process in real time. With the computer’s data statistics and analysis capabilities, the detection accuracy can reach ±0.2 mm, which greatly reduces the probability of gluing failure.
“From the early days of the factory, a complete vehicle was rolled off the assembly line every 120 seconds, to now 72 seconds. Intelligent upgrades have not only improved product quality, but also improved production efficiency.” Zhang Wenjun said, “In the past few years, the Yongchuan factory has put in new transportation , spraying, welding and other intelligent equipment, with an investment of over 100 million yuan. Through the application of information systems, flexible scheduling and other technologies, the factory’s production capacity continues to improve.”
“In recent years, Yongchuan District has actively promoted the in-depth integration of digital technology and manufacturing, and introduced relevant plans to clarify the direction, goals and implementation paths of the intelligent transformation of the automobile industry. Through the demonstration of leading enterprises, it collaborates with upstream and downstream enterprises in the automobile industry chain to carry out intelligent transformation .” said Li Jia, chief of the Intelligentization Section of Yongchuan District Economic and Information Technology Commission.
Nobo Auto Parts (Chongqing) Co., Ltd. is one of Great Wall Motor’s suppliers in Yongchuan. Now, by connecting to Great Wall Motors’ self-developed production management system, Nobo Motors’ production plans are more scientific and efficient. “At present, all our upstream and downstream enterprises in Yongchuan have been connected to the production management system. The system can automatically formulate production plans based on the enterprise’s production capacity and market demand, and make adjustments according to actual conditions to improve production efficiency and product quality.” Zhang Wenjun said .
“Since 2018, we have secured a total of more than 130 million yuan in smart manufacturing-related awards and subsidies for Yongchuan companies, encouraged companies to carry out intelligent equipment upgrades, integrated applications of information management systems, and industrial Internet platform construction, and implemented a total of 374 smart transformation projects. to guide enterprises to further deepen the innovative integration and application of digital technology and manufacturing.” Li Jia said.
