Abstract
A 3D processing device configured to attach a decorative film on a surface of a 3D glass, the 3D processing device includes a decorative film pre-deformation unit and a attachment unit. The decorative film pre-deformation unit includes an upper mould and a lower mould opposite to the upper mould, wherein the upper mould engages the lower mould to press the decorative film and cause the decorative film to have a shape matching a surface of the 3D glass. The attachment unit defines a sealing chamber, and includes a mould and a gas bag within the sealing chamber, wherein the mould is configured to support the 3D glass. The present disclosure further provides a method thereof.
