TECHNICAL FIELD
[0001] The application relates to the field of battery rubberizing, in particular to a novel rubberizing mechanism. BACKGROUND
[0002] In the preparation process of the winding type battery cell, the positive electrode sheet, the diaphragm and the negative electrode sheet are formed into a laminated structure through winding. Among them, the positive electrode sheet usually takes foil as the current collector. However, due to the relatively low ductility of the foil material, in the pressure shaping process after the winding of the battery cell, the positive electrode sheet is easily affected by the mechanical stress concentration in the winding corner area, that is, the curvature mutation position of the straight line segment to the circular arc segment of the electrode sheet, which causes micro-cracks or even tearing defects of the foil substrate. Such defects not only cause the active material to fall off and reduce the battery capacity, but also may cause internal short circuit and other safety hazards. The existing technology generally adopts the process scheme of pre-taping the positive electrode sheet winding corner position, which disperses the stress through the adhesion and reinforcement of the tape, thereby improving the tearing resistance of the foil. However, the traditional taping assembly device can only perform single-sided taping, and cannot simultaneously perform double-sided taping, resulting in poor taping efficiency of the foil. SUMMARY
