An adhesive strip attaching device comprising a material loading assembly (100) for inputting a product to which an adhesive is to be attached, an adhesive attaching platform (200), a conveying assembly (300), a material discharging assembly (400), and an adhesive attaching assembly (500). The conveying assembly (300) is used to convey the product to the adhesive attaching platform (200) such that the adhesive attaching assembly (500) attaches an adhesive to the product. The conveying assembly (300) is further used to convey the product, to which the adhesive has been attached, in the adhesive attaching platform (200) to the material discharging assembly (400). The adhesive attaching assembly (500) comprises a material loading roller (510), a material discharging roller (520), a cutting unit, and an adhesive feeding unit. The material loading roller (510) is used to wind an adhesive tape to be used. The adhesive tape comprises a double-sided adhesive and a release paper attached to one side of the double-sided adhesive. The material discharging roller (520) is used to pull the release paper to separate the release paper from the double-sided adhesive. The cutting unit is used to cut the double-sided adhesive. The adhesive feeding unit is used to pull the double-sided adhesive, convey the cut double-sided adhesive to the adhesive attaching platform (200), and attach same to a surface of the product. The adhesive strip attaching device corrects an offset of the double-sided adhesive, thereby improving the efficiency of applying an adhesive.
