Robots open a new model of "smart manufacturing" ships

In the three automated robotic production lines in the inner (hull) workshop of Nantong COSCO Kawasaki Ship Engineering Co. , the robots are constantly wielding smart arms to work. In the past, the two processes of marking and cutting the Nantong COSCO Kawasaki steel plate were completed manually, which not only had a long working time but also was labor intensive. Right now, only one worker can click the mouse to release the "command" to be completed by the robot. Today, this high-efficiency, low-intensity production mode has become the "new normal" of the Nantong COSCO Kawasaki internal workshop.

As the robots entered the shipyard team workshop and gradually applied in the construction of ships such as cutting, welding and painting, many domestic shipping companies have opened a new mode of “intelligent manufacturing”.

     Under the scorching sun, it is a torment for the welders, sanders and painters in the shipyard. Replacing manual work with robots not only frees workers from the “hard, dirty, tired” working environment, but also promotes the shipbuilding production process to reinvent the wheel and promote the efficiency of shipbuilding. This expectation is now becoming a reality. As robots are more widely used in shipyard processes, more and more shipyards in China have realized the advantages of “smart manufacturing” in improving shipbuilding efficiency and improving shipbuilding accuracy.

     The number of profiles in the Nantong COSCO Kawasaki internal workshop profile group was up to 36. After the introduction of the automated production line, the number of personnel was reduced by half. At the same time, the scribing and cutting of the steel is all done by the robot. The worker only needs to confirm the operation with the computer and view it next to it. One person can complete the workload of 6 people. Moreover, the original steel required to cut a segment takes 3 days, and now it can be completed in half a day, and 160 to 170 angles can be cut every day . In addition, the information such as the cutting size and standard of all profiles and strips are designed and corrected by the company's design department and input into the information system. The networked automated production line divides, cuts and transports according to the specifications to ensure the accuracy of product quality. And stability. Through nearly four years of application, most of the workshops of Nantong COSCO Kawasaki have been automated. The disposable utilization rate of steel plates is 92% , and the repeated utilization rate is over 95% . Three automated production lines have increased the production efficiency of the corresponding processes by about 70%. .

     As the key to the next generation of technological revolution, robots have brought enormous challenges and unlimited imagination to the shipbuilding industry in traditional industries, especially in traditional manufacturing. The non-standardization and customization features of marine products have brought certain difficulties to the production of robots by shipbuilding enterprises. However, after years of development, it has become a reality that robots participate in shipbuilding and contribute to the development of the shipbuilding industry.
