[0072] The door panel laminating device 3 provided in the present embodiment is constructed by forming a clamping laminating space suitable for the door panel to pass through between the driving roller 32 and the upper film roller 33. In the specific laminating stage, the driving roller 32 and the upper film roller 33 are clamped and pressed against the door panel, and the driving component drives the driving roller 32 to rotate to drive the door panel to pass through the clamping laminating space. The protective film transferred to the upper film roller 33 by the upper film mechanism 35 is attached to the upper end surface of the door panel by the pressing action of the upper film roller 33 and the door panel, and the protective film transferred to the driving roller 32 by the lower film mechanism 37 is attached to the lower end surface of the door panel by the pressing action of the driving roller 32 and the door panel.
