The welding line project of Geely Changxing Base

This project involves the construction of an automatic production line for the cabin floor and sub-assembly area, with a total of 67 robots, capable of meeting the flexible co-production requirements of various vehicle models. The project team conducted an analysis of the manufacturing process of the target model, optimized the process flow, and carried out intelligent design for the welding workshop to maximize the performance of the production line. The production cycle of this welding line reaches 60JPH, making it one of the welding lines with the highest production cycle in China. The total project amount of Shandong Institute of Advanced Technology at Geely Changxing Base has accumulated to over 91.8 million yuan, demonstrating the client's recognition of our company's technical capabilities and service quality. During the project's advancement, the company actively introduced advanced technologies, among which virtual simulation digital twin technology was fully and thoroughly applied in the Changxing HY11 project. The application of this technology has greatly simplified the on-site commissioning workload, reduced the commissioning difficulty, and significantly decreased the failure rate during the on-site commissioning process, providing a solid guarantee for the efficient advancement and stable operation of the project.

The welding line project of Geely Guiyang Base

This project will add manual welding tooling equipment for sub-assemblies, renovate the tooling equipment, inter-line conveying systems, electrical control systems, robot system auxiliary equipment and robot system integration of the engine room line, front floor line and rear floor line, and all other supporting facilities related to the line body, to create an intelligent production line. The welding team conducted an analysis of the manufacturing process for the target model, optimized the process flow, and carried out intelligent design for the welding workshop. They adopted advanced process technologies and equipment, and employed 75 robots for operation, including spot welding robots, handling robots, arc welding robots, fully automatic transfer and conveying systems, and other intelligent manufacturing equipment, to ensure high speed, high flexibility, and full-line automation. After the intelligent welding and assembly production line is completed, it can meet the flexible co-production demands of three platforms and multiple vehicle models on the same line, with an expected annual production capacity of 270,000 vehicles.

The welding line project of Geely Jinzhong Base

In this project, Shandong Institute of Advanced Technology will carry out the introduction of new models while ensuring the production capacity and configuration of the original three mass-produced models remain unchanged. The renovation scope includes the engine room line, the rear floor line, the main assembly line of the lower vehicle body, the main assembly line and two aerial conveyor lines, and new manual lines for the front floor and three-level sub-assemblies are added. The side panel line was completed with the addition of vehicle model recognition and the debugging of the robot program, and finally the co-production of flexible lines for four types of vehicles was achieved. Through the flexible and intelligent upgrading of the welding workshop, the investment cost and time cost of the new production line have been reduced, thereby maximizing the benefits of the production line. This project was time-pressured, labor-intensive and technically challenging. The project team overcame numerous difficulties, worked overtime and finally successfully completed the task. They achieved the automatic production of the new model and the double-line operation of the mass production model 12 days ahead of schedule.

Geely Linhai Base Welding and Assembly Line Project

Linhai is the birthplace of Geely sedans. During the advancement of the Geely Linhai P145 project, Shandong Advanced Institute flexibly adjusted its work plan in response to multiple demand changes, achieving mass production capacity one month ahead of schedule, thus gaining a precious time advantage for the project's progress. After the mass production was launched, the project team continuously optimized the production line. Currently, the production capacity has far exceeded the original design indicators, and it has achieved a high degree of stability and continuity. The operational reliability has reached the industry-leading level, setting the fastest record of delivering 10,000 new vehicles just 13 days after their launch.

The welding line project of Jili Meishan and Chunxiao bases

Geely Meishan and Chunxiao bases, as high-end platforms of Geely ZEEKR, have over a hundred flexible robots in their welding workshops. The welding process is automated and can be called "dark factories". Even when the lights are off, they can be precisely controlled. They have stricter standards in terms of project cycle and product quality, which not only reflects our company's advantages in technical level, It is even a severe test of our company's project management ability and comprehensive strength. The project involves the renovation of the inner side panel line, outer side panel line, and top cover line, the construction of a new aluminum shock absorber line, the renovation of the front and rear floor lines of the engine room and the introduction of new vehicle models, including the addition or renovation of tooling equipment, in-line conveying systems, electrical control systems, robot system auxiliary equipment, and robot system integration, as well as all other supporting facilities related to the line body, to meet the flexible co-production requirements of multiple vehicle models on the production line.
During the project scheme design process, the welding and assembly team fully exerted their innovative spirit, broke the routine, optimized the process design flow, and adopted a series of advanced process technologies and equipment. This includes Arplas welding technology for enhancing the appearance quality of vehicle bodies, Dimple dedicated workstations for ensuring the stability and accuracy of the welding process, CMT automatic cold arc welding technology for reducing sheet metal welding deformation, SPR self-piercing riveting technology for integrating multiple materials with aerospace processes, aluminum stud welding technology for improving welding quality and efficiency, as well as visually guided griders and gluing Visual surveillance, etc. At the design end, the welding and assembly team adopted a simulation synchronous process design, focusing on simulation optimization for risky workstations, effectively reducing the risks of equipment debugging in the later stage and laying a solid foundation for large-scale and high-quality line construction in the later stage.
