The utility model discloses a back adhesive fitting mechanism which comprises a release film unwinding roller, a double-sided adhesive unwinding roller, a heat-radiating film unwinding roller, an insulated adhesive tape unwinding roller, guide rollers, fitting rollers and a winding roller, wherein the guide rollers respectively correspond to the release film unwinding roller, the double-sided adhesive unwinding roller, the heat-radiating film unwinding roller and the insulated adhesive tape unwinding roller; the fitting rollers are positioned at the rear ends of the guide rollers; the winding roller is positioned at the rear end of the fitting rollers. The back adhesive fitting mechanism further comprises a group of embossing rollers positioned at the rear ends of the heat-radiating film unwinding roller and the corresponding guide roller; the embossing rollers are positioned between the heat-radiating film unwinding roller and the fitting rollers. The back adhesive fitting mechanism has the benefits that the two surfaces of a heat-radiating film before a back adhesive is fitted are subjected to grain forming through the one group of embossing rollers; during back adhesive fitting, grains on the two sides of a heat conduction layer can be utilized for driving internal air bubbles away so as to form a heat-radiating adhesive tape without air bubbles, therefore, the product quality and the use effect are effectively ensured.
