10. A bonding method for a mobile phone battery cover heat dissipation film bonding device, comprising the mobile phone battery cover heat dissipation film bonding device according to claim 1, characterized in that, Includes the following steps: S1: First, place the produced mobile phone battery cover between two conveyor belts (3) in sequence, and then start the drive unit (2) to move the mobile phone battery cover to the position of the hollow top plate (6) through the conveyor belt (3); S2: When the mobile phone battery cover moves directly above the hollow top plate (6), the first telescopic cylinder (5) is activated. The first telescopic cylinder (5) will drive the hollow top plate (6) to move upward and cause the first air cylinder (7) to suck air from the hollow top plate (6). When the suction cup on the hollow top plate (6) contacts the bottom of the mobile phone battery cover, the mobile phone battery cover can be adsorbed and fixed under the action of negative pressure. S3: Then, the heat dissipation film connected by the easy-tear indentation line on the film is transferred to the top of the phone battery case through the film application component; S4: At this time, the second telescopic cylinder (18) can be activated to move the hollow pressure plate (20) downward, and the second air cylinder (23) will suck air into the hollow pressure plate (20). When the hollow pressure plate (20) contacts the heat dissipation film, the hollow pressure plate (20) will adsorb the heat dissipation film under the action of negative pressure. Then continue to control the hollow pressure plate (20) to move downward. When the heat dissipation film contacts the mobile phone battery cover, the heat dissipation film will firmly adhere to the mobile phone battery cover under the pressure of the hollow pressure plate (20). S5: Finally, control the first telescopic cylinder (5) and the second telescopic cylinder (18) to retract, so that the hollow top plate (6), the hollow pressure plate (20) are separated from the mobile phone battery cover and the heat dissipation film. Then start the drive unit (2) to transport the mobile phone battery cover with the heat dissipation film attached away, and transport the next mobile phone battery cover directly above the hollow top plate (6). Repeat this process to continuously apply the film to the mobile phone battery cover.
