#超级增程S7刷新行业交付记录#
The output of a high-quality product is inseparable from the requirements of excellence, any flaw, may cause a chain reaction, ultimately affect the stability of the car, and the navy brand can constantly refresh its own delivery record, but also because of this butterfly effect. Decipher the manufacturing process of Deep Blue S7 now
Science and technology "intelligent" manufacturing, quality confidence
The first is stamping, and what the vehicle looks like depends to a large extent on this step. The appearance of navy S7 has two characteristics, one is that the lines are richer and more broken lines, the other is the use of borderless door design, which has higher requirements for the production accuracy of parts, Nanjing smart factory positioning is a new new energy personalized customization demonstration plant, stamping technology using intelligent flexible detection system, design accuracy requirements plus or minus 0.5mm (industry level is plus or minus 1mm), far beyond the industry level, can also real-time big data analysis A surface quality status, highly restored modeling design, restoration degree of 95%, Leading the industry by 5%, laying a good foundation for subsequent production.
The second step of welding, Nanjing smart factory industry first welding joint online detection technology, vehicle welding self-inspection rate of 60%, high automation to ensure assembly quality consistency, there are up to 215 robots on the production line, the quality of the body surface off the heavy welding joint coverage 100% confirmation. The welding process realizes four doors and two covers through visual guidance and robot automatic assembly technology, and the shooting accuracy is plus or minus 0.3mm, and only Volkswagen, Mercedes-Benz and NIO in the industry can achieve automatic assembly.
The third step is painting, compared to the navy SL03, the color choice of navy S7 is richer, which also adds difficulty to the coating process, in order to make the dark blue S7 paint surface more glossy, the color is more textured, the factory uses solid primer matching pearlescent paint layer of two-color paint coating spraying process and 10 micron dust-free workshop, the painting process up to 70% automation rate, in order to ensure the color and smooth effect of the vehicle paint. In addition, the folded line design mentioned earlier in the package, this style has high requirements not only for stamping, but also for the painting process.
Finally, the final assembly is the process of assembling all the components together, and good accessories can become really good products after good assembly technology. Nanjing Smart Factory can realize large-scale customized assembly, zero quality error, and automatic chassis assembly. Layers of control to achieve high-quality delivery, from parts and materials to vehicle delivery 11 quality wall control.
After the final assembly line comes off the production line, the vehicle also undergoes a series of quality tests to ensure that the products delivered to each delivery to the user are of high standard, and from the appearance of this navy S7, its sporty styling design, extreme space utilization and dynamic details are the best proof of quality. Based on the hard core manufacturing process of Deep Blue Automobile, the vehicle has a height to length ratio of 34.2%, a height to width ratio of 84.2%, and a class-leading 0.258Cd, sharp control ready to go! This is also an important basis for a longer range.
