Abstract: An adhesive application apparatus and a battery production line are provided. The adhesive application apparatus includes an unwinding mechanism, a first winding mechanism, an adhesive application mechanism, and a second winding mechanism. The unwinding mechanism is configured to dispose and unwind the double-sided adhesive. The first winding mechanism is configured to peel off and wind the first release paper. The adhesive application mechanism and the winding mechanism jointly define a first path, where the first path is used to guide the adhesive strip to move forward. The adhesive application mechanism includes an adhesive application member disposed on a side of the first path, where the adhesive application member is configured to applies pressure from a side of the first path to the double-sided adhesive, so as to attach the adhesive strip on an object surface. The second winding mechanism is configured to peel off and wind the second release paper.
