[0043] When the film is stripped, the initial separation between the protective film and the film material is moved to the cutting edge of the stripping knife 4 (the motor of the winding roller 31 is stopped, and the outer suction head sucks the protective film on the film material), the film pressing member 622 is pressed to fix the film material in the direction of the stripping knife 4, then the stripping driving member 52 drives the stripping displacement member 51 to move towards the film feeding mechanism, and then the stripping knife 4 and the first pressure stabilizing roller 611 are driven to move, the film material is pulled towards the film feeding mechanism to achieve the separation of the protective film and the film material, and due to the existence of the first pressure stabilizing roller 611 and the second pressure stabilizing roller 612, the film material can maintain a Z-shaped movement track at the stripping mechanism when the stripping guide moves to any position, so that the stripping angle of the film material is consistent, and the existence of the second pressure stabilizing roller 612 can make the movement distance of the film material between the stripping guide and the encapsulation shaft 33 always consistent (the distance between the first pressure stabilizing roller 611 and the second pressure stabilizing roller 612 increases by the same distance as the movement distance of the stripping knife 4, that is, the film material is stripped by how much, and the film material is pulled away by the same length, the distance between the first pressure stabilizing roller 611 and the second pressure stabilizing roller 612 increases to play the role of pulling the film material, and since the angle is consistent when the film is stripped, only the uniform motion of the stripping displacement member 51 can keep the tension stable when the film is stripped), the winding motor 35 does not work during the stripping process, and the ion wind rod 9 continuously blows air to the stripping position to eliminate static electricity during the stripping process; after the stripping is completed, the outer suction head drives the protective film to pass through the film output detection sensor 8, and if the detection is unqualified, the protective film is directly attached to the unqualified adhesive block, and if the detection is qualified, the protective film is sent to the film attaching work for film attaching; after the suction head takes away the protective film, the film pressing member 622 reversely displaces, the stripping displacement member 51 reversely moves back to the initial position, and the winding motor 35 rotates again to drive the film material to move, so that the subsequent part of the film material with the protective film moves to the stripping knife 4, and the above cycle is repeated.
