Background

Due to the structural advantages of the blade battery, the hot runaway possibly occurring in the traditional power battery during the needling penetration test is thoroughly eliminated, the safety standard of a new energy automobile is redefined, and the safety new altitude of the global power battery is led. However, the blade type battery shell also puts forward a strict requirement on the product quality of the aluminum alloy coiled material for manufacturing the blade type battery shell, and besides general mechanical performance and surface quality, the blade type battery shell also puts forward a stricter requirement on the control of the cut edge quality (camber and cut edge burrs) of the aluminum alloy coiled material after cutting, and particularly the camber after cutting influences the welding quality and air tightness after forming. The existing non-ferrous metal coil slitting production line generally comprises an uncoiler, an uncoiling tensioning roller mechanism and slitting equipment which are sequentially arranged along the production line direction. The aluminum alloy slitting coiled material manufactured by the existing nonferrous metal coiled material slitting production line often has the defect of slight camber, and the requirement of the blade battery on the edge slitting quality is difficult to meet. Therefore, a scheme capable of solving the problem that the aluminum alloy slit coiled material is easy to have the camber defect is urgently needed.
