The manufacturing process of CTP battery packs (Cell to Pack, cell to Cell is integrated into a battery Pack) is very different from that of conventional battery packs, and when CTP battery packs are manufactured, double-sided tape needs to be adhered to the surface of the Cell by using an automatic tape sticking machine. The automatic rubberizing machine for manufacturing the CTP battery pack integrates rubberizing, die cutting and feeding modules, directly places rolled double-sided adhesive materials on the feeding modules, die cuts the rolled double-sided adhesive materials through a die cutting unit, and finally adheres the cut double-sided adhesive materials on the surfaces of the battery cells and the battery pack. Because the existing automatic rubberizing machine integrates procedures such as die cutting and rubberizing, and the rubberizing time is relatively long, the die cutting efficiency is not optimal, the size of rolled double-sided adhesive material is large (the diameter of the double-sided adhesive material is generally more than 1 m), and the setting of the double-sided adhesive material with large roll diameter on the automatic rubberizing machine can occupy excessive space. Because the winding diameter of the double-sided adhesive material on the market is overlarge at present, the automatic adhesive tape sticking machine occupies larger space during working, and therefore, the space utilization rate in a processing workshop is lower. Thus, it is necessary to provide a double-sided adhesive material having a smaller roll diameter.
Based on the above considerations, in order to be able to process double-sided adhesive material having an excessively large roll diameter into double-sided adhesive material having a smaller roll diameter, the applicant has conducted intensive studies and devised a double-sided adhesive material processing apparatus for processing double-sided adhesive material including an unreeling unit, a die cutting unit, and a reeling unit. After being unreeled by the unreeling unit, the double-sided adhesive material is changed into a strip shape from a roll shape, the double-sided adhesive material in the strip shape is conveyed to the die cutting unit, a cutting mechanism in the die cutting unit cuts the double-sided adhesive material into a preset length without cutting off the original first isolation paper in the double-sided adhesive material, therefore, the first isolation paper which is not cut off can continue to move and convey the double-sided adhesive material to the reeling unit, finally, the cut double-sided adhesive material and the first isolation paper are reeled by the reeling unit, when the double-sided adhesive material in the reeling unit reaches a proper reeling diameter, the first isolation paper positioned in the reeling unit can be cut off, and thus, the double-sided adhesive material with a larger reeling diameter can be processed into the double-sided adhesive material with a smaller reeling diameter.
