Processing device and processing method of aluminum foil for battery

The invention provides a processing device and method for aluminum foil for batteries, and relates to the field of aluminum foil processing.The processing device comprises a cold rolling mechanism, an annealing mechanism, a rough rolling mechanism, an intermediate rolling mechanism, a finish rolling mechanism and a slitting mechanism; the aluminum foil is subjected to cold rolling treatment through the first rolling assembly, the second rolling assembly and the third rolling assembly in sequence, then is subjected to annealing treatment through the annealing mechanism, finally is subjected to cold rolling treatment multiple times through the rough rolling mechanism, the intermediate rolling mechanism and the finish rolling mechanism in sequence, and finally is subjected to edge cutting treatment through the slitting mechanism. The gaps among the first rolling assembly, the second rolling assembly and the third rolling assembly are sequentially reduced, the proper number of finish rolling mechanisms can be sel
