It is known in the automotive industry to design passenger cars with a roof (integral structural weldment) that is welded structurally and then covered with a 2mm aluminum sheet (weatherproof, about 10 meters in size and about 2.2 meters in width) on the arc roof, which is called the roof skin of the passenger car. The passenger car roof skin is made of aluminum coils through drawing and cutting.

At present, the manual operation method is adopted in the automobile industry to draw and cut the cover skin of the top cover of the passenger car. The working personnel firstly pull the aluminum coil by the required length manually, and then measure and cut the aluminum plate manually to obtain the passenger car roof covering. However, because the size of the roof cover skin of the passenger car is large (about 10 meters long and about 2.2 meters wide), 6 to 7 people are needed to pull the roof cover skin to be pulled out of the aluminum coil, so that more manpower is consumed, and the working efficiency is low. Moreover, the manual cutting and positioning are inaccurate, the cover of the top cover of the passenger car needs to be cut again in the subsequent processing, and the material is wasted. In addition, the thickness of the aluminum coil is very thin, and great potential safety hazards exist in the manual pulling process.
