Background The aluminum/aluminum composite board is widely applied to the fields of heat exchangers, building decorations, rail transit and the like. The typical production process comprises polishing the composite surfaces of aluminum sheet (thin plate) and aluminum ingot (thick plate) respectively to remove oxide layer and activate surface, bonding the polished surfaces to each other, and rolling or pressing to realize metallurgical bonding. In the prior art, polishing is separated from the compounding process. The aluminum sheet and the aluminum ingot are polished, stacked and transported on independent production lines, and then are concentrated to a compound device for superposition. The surface of the aluminum material is exposed to the air for a few minutes to a few hours after polishing, so that a compact oxide film is rapidly formed, and the bonding strength of a composite interface is seriously weakened. And the aluminum sheet is warped due to stress release after polishing, and is difficult to be tightly attached to the surface of an aluminum ingot in subsequent lamination, and air is easy to remain between layers to form bubbles or virtual attachment. Aluminum scraps and abrasive particles generated by polishing float in the air or are deposited on the surface of a roller way, so that the aluminum scraps and abrasive particles are easily transferred to the polished clean surface, and the defect of inclusion of a composite interface is caused. To solve the above problems, those skilled in the art have tried to shorten the distance between the polishing wire and the composite wire, add a dust cover, add a panel turnover machine, and the like. However, the existing improvement still remains in the process connection level, the offline production mode of firstly polishing, storing and then taking the compound is not changed fundamentally, and the gold time of the surface activity after polishing is still wasted in the logistics waiting in a large amount.
