Automatic production line of battery

The invention discloses an automatic production line of a battery. The automatic production line comprises a pole piece unreeling device, a pole piece feeding mechanism and a battery pole piece; and the pole piece feeding mechanism drives a battery pole piece to be rolled and conveyed to a preset position from a pole piece unwinding roll, wherein a laser cleaning mechanism, a pole lug welding mechanism and a protective glue pasting mechanism are arranged on a conveying path of the battery pole piece, and wherein a winding mechanism, a diaphragm feeding mechanism and a sticking ending mechanism are arranged on the pole piece feeding mechanism. The battery pole piece is subjected to integrated automatic production work such as cleaning, winding and protective glue pasting, each working procedure does not need to be independently controlled manually, the machining process steps are greatly simplified, the machining efficiency is improved, and the operation difficulty is reduced. Compared with the prior art, the
