[0002] Notebook refers to a notebook computer, which is a portable computer. Compared with a desktop computer, a notebook computer has the advantages of portability and lightness. The shell of a notebook computer is the most direct way to protect the machine body and is an important factor affecting its heat dissipation effect, weight and aesthetics. Common shell materials for notebook computers include alloy shells such as aluminum-magnesium alloy and titanium alloy, and plastic shells such as carbon fiber, polycarbonate PC and ABS engineering plastic.

[0003] When a notebook computer is shipped, a plastic film is often covered on the shell to protect the notebook computer during transportation. Traditional notebook shell film pasting devices often directly blow the film onto the notebook shell. Such operation may cause irregular pasting or air bubbles during the pasting operation, which is inconvenient for protection during transportation and affects the aesthetics. At the same time, traditional pasting operations often involve pasting a film on one side of the notebook computer and then pasting a film on the other side. This low-efficiency pasting operation cannot guarantee the consistency of the pasting operation on both sides of the notebook computer.
