Holding the two trump cards of "Magna" and "Digitalization", Jihu Automobile creates manufacturing quality with high standards, creates differentiated advantages with digitalization, and finds new breakthrough points for the intelligent + electric track.
Magna, a diversified global auto parts supplier with more than 100 years of experience and history in high-end car manufacturing, has produced more than 3.7 million vehicles, including mercedes-Benz G-Class, Aston Martin Rapide and other top luxury cars. The Beiqi Blue Valley Magna Intelligent Manufacturing Base is Magna's first vehicle manufacturing plant outside of Europe and the first Magna joint venture high-end intelligent manufacturing base in Asia. On December 23rd, Beiqi Blue Valley Magna Intelligent Manufacturing Base held an OPEN DAY, disclosing the manufacturing process and production details of this Jihu Jizhi factory to the outside world, showing the secret behind the high quality of Jihu Automobile.
Strengthen digital operations with MAFACT as the standard
As a high-end new energy vehicle manufacturing base jointly built by BAIC Group and Magna, BAIC Blue Valley Magna Intelligent Manufacturing Base has introduced the Magna MAFACT production and operation management system, mainly producing ARCFOX Jihu series models with world-class manufacturing standards of first-line luxury vehicles, and opening them to potential customers to provide electric vehicle research and development and vehicle manufacturing services.
While taking Magna's MAFACT production and operation management system as the standard, The Beiqi Blue Valley Magna Intelligent Manufacturing Base also introduces automated production lines and robotic arms for the stamping workshop, body workshop, painting workshop, assembly workshop and battery PACK workshop to strengthen digital operations.
The stamping workshop, which has been set up at present, is a fully enclosed, high-speed automated production line, which can realize the mixed production of steel and aluminum, mainly responsible for the production of large and medium-sized stamping parts such as side walls, fenders, door covers and so on. According to the stamping process engineer Zhou Fang, "the stamping workshop has a total of 40 self-made parts (including 15 aluminum parts), according to the MAFACT system standards, from the material to the final product, from the appliance to the equipment, all-round in-depth control, a pass rate of 97%, and most of the main engine factories of the indicator is about 90%. ”
In the body workshop, Beiqi Blue Valley Magna high-end intelligent manufacturing base has the first 30JPH steel and aluminum hybrid production line in China, which is a fully automated production line composed of 290 German KUKA robots and 206 sets of connected equipment. The painting workshop is equipped with a total of 52 ABB high-performance robots, which form a fully automatic conveying system, and after multiple coating processes, the LASD water-based damping coating prepared by adding the appropriate amount of polymer resin to the appropriate amount of filler and auxiliary materials will be automatically sprayed to the body.
Final assembly workshop for a high degree of automation. Vehicle online real-time monitoring, automatic reporting of vehicle location; key processes automatic identification, automatic tightening. The key equipment of the chassis automatically measures and automatically adjusts to the qualified range, and at the same time can be automatically calibrated and calibrated at regular intervals.
In the battery PACK workshop, the automatic rate of the whole line has also reached 53%, including automatic on-line of the module, automatic detection, gluing, cleaning, and module installation, fixing, FDS riveting process and so on. Zhu Juncheng, battery PACK process engineer, said: "Through high automation, the precision, consistency and higher production efficiency of the overall process are guaranteed, and the battery safety is more secure. ”
Testing is very important And high quality is recognized
Magna MAFACT production and operation management system sets standards, automated production lines to ensure product accuracy and production efficiency, coupled with Jihu Automobile's excellence in the whole process of material selection, manufacturing and testing, Jihu Automobile has won the "China's Top Ten Body" and "Best Material" double material awards this year, and the platinum grade of the first batch of corrosion resistance evaluation in CA-CAP.
For the Pole Fox Alpha S to be able to obtain a 5-star evaluation in the test evaluation results of China's automobile corrosion resistance and aging performance evaluation (CA-CAP), and won the first batch of vehicle corrosion resistance test evaluation platinum grade certificate with a score of 92.3 points, Duan Lifei, product director of Polar Fox Automobile Alpha S, commented, "I have a very big understanding of the anti-corrosion level of Chinese automotive products and Polar Fox automobiles, that is, the anti-corrosion at this stage has achieved high quality. ”
In fact, whether it is corrosion resistance test or ice and snow test, Jihu Automobile has shown a relatively high level. In the view of Ji Guowei, secretary of the party committee and general manager of Magna of Beiqi Blue Valley, "testing is very important in both the development stage and the manufacturing process." "In layman's terms, it is to do enough basic skills in advance.
Ji Guowei said that in the development stage, from the assembly to the verification of each subsystem, many will be completed in the experimental center and carried out in accordance with the specific experimental standards of the Magna Engineering Development Specification. It is reported that this experimental center focuses on the relevant tests of three electric vehicles, electric vehicles and intelligent vehicles, and also verifies the chassis of the whole vehicle.
In terms of manufacturing, Beiqi Blue Valley Magna's high-end intelligent manufacturing base includes stamping workshop, body workshop, painting workshop, assembly workshop, and battery PACK workshop. "Taking the stamping workshop as an example, the bumps on the surface of the stamping parts, some of which cannot be seen by the naked eye and cannot be touched by the hand, we have used special inspection methods, including flexible sand nets, to expose related defects in advance, so as to take relevant measures in time."
"In terms of final assembly, we also have a rigorous inspection process, including repeated verification of software, including the grasp of the supply chain. Jihu Automobile cooperates with World-class enterprises such as Huawei, Magna, and Bosch, and these excellent suppliers and our management of suppliers jointly promote the improvement of vehicle quality. Ji Guowei said.
