NISSAN, the pioneer of Smart Mobility vision, announced that it has invested $ 300 million in its advanced technology and equipment to be used in all its factories. This investment of NISSAN; will make production operations more flexible, efficient and sustainable while helping the company deliver a new generation of electric and smart cars that adopt the NISSAN Smart Mobility vision.
NISSAN introduced the innovations at the Tochigi Factory in Japan for the first time, and by 2020, NISSAN will apply the new production technology to its factories in different countries.
Since 1933, NISSAN has brought production vehicles to the highest standards possible, and with the latest investment, NISSAN is reviewing traditional automobile construction and addressing the structural and technical challenges of vehicle production that will lead the sector in the new electrification and intelligence era. Hideyuki Sakamoto, Vice President of Production and Supply Chain Management at NISSAN, said that they are facing an unprecedented evolution in the capacity of their vehicles; Görev Our mission is to revise car production and make this evolution a reality. This also means shifting the existing skills of our expert technicians from the techniques they master to new and unexplored areas..
Building the future of mobility
NISSAN's next generation of electric, intelligent and connected cars bring a new operational process to the design and construction process that requires major advances in manufacturing engineering. One of these developments is the Güç Universal Powertrain Assembly System geliştiril developed by NISSAN's Manufacturing Engineering Research and Development Center.
The assembly line used for power transmission in automobiles became a long and tiring process for assembly line personnel, since multiple operations were required in order. using pallet. The system measures the dimensions of the vehicle in real time during assembly, and the pallet makes micro adjustments to ensure that the powertrain is mounted in millimetric accuracy.
With the new system, the same pallet can mount three types of powertrain (internal combustion engine, e-POWER and pure electricity) and assemble and assemble 27 different powertrain combinations.
Teaching robots mastery
With new technology, NISSAN will use “trained robots için to enable its masters to focus on new, unexplored areas of expertise. So far, NISSAN digitizes some business processes that can only be performed by trained craftsmen and require specialist skills, and in some of these processes use trained robots.
An example of these processes is the application of a paste-like material to the seams around the vehicle body to provide waterproofing.
Because the necessary dexterity and speed can only be achieved through training, this practice is usually done by experts, while replicating this skill and speed is a very difficult and long process. Automating the sealant application process, NISSAN engineers smoothed and finished the sealant, analyzing the body movements of trained workers and calculating the pressure applied at each stage. They then converted this information into instructions for robots and further elaborated through extensive trial and error.
As a result of these efforts, robots are now able to complete the work by applying insulation materials quickly and precisely even in the most complex locations.
A better workplace can be built with robots
NISSAN now allows robots to perform a number of difficult tasks efficiently, while allowing employees to move freely to perform more important tasks elsewhere on the line. This also improves ergonomics, making it easier for factories to work. An example of this is the installation of the ceiling covering, which is the top layer material on the inside of an automobile's roof.
Workers must physically enter the car's cabin to perform this demanding job. This has become even more difficult as the cars have more digital features and the number of devices in and around the hoods increases.
NISSAN has started to use the robots he has trained to solve this problem. Using robots to place the roof trim in the front of the vehicle and then fix it, NISSAN's sensors monitor changes in pressure and use a special logic system to determine that the clips are firmly seated.
Low environmental impact
NISSAN is also working to reduce the environmental impact of automobile production. Especially the changes in the dyeing process are remarkable. Since the viscosity of the paint is difficult to control at low temperatures, automobile bodies usually need to be painted at high temperatures. However, since the bumpers are made of plastic, the dyeing process is carried out at low temperatures. This requires two separate painting processes for one vehicle.
NISSAN developed a water-based paint to maintain accurate fluidity at low temperatures, enabling the body and buffers to be co-dyed, resulting in a 25 percent reduction in carbon dioxide emissions from this process.
NISSAN will also use a waterless paint booth to enable the collection and reuse of all waste paints in its new production processes.
Stating that the technologies and innovations they developed are at the center of the company's competitiveness, Sakamoto said; “These technologies and innovations will become more and more widespread in the coming years and will form the basis of the future of NISSAN Smart Mobility and reinforce our leadership in technology.”
