3D film attaching equipment and 3D film attaching method

Abstract

The invention provides 3D film attaching equipment and a 3D film attaching method. The equipment comprises a mold core, a mold cavity, a heating device, a sealing cavity and a first driving device, wherein the sealing cavity is communicated with an external vacuumzing device, and the first driving device is arranged in the sealing cavity and is used for driving the mold core to move back and forth relative to the mold cavity and respectively maintaining the mold core at a primary attaching position and a first position, and the first position is far from a film piece primarily attached to a to-be-film-attached workpiece by a first preset distance; a negative pressure channel communicated with the vacuumzing device, is further arranged in the mold core, and a plurality of air suction holes which are communicated with the negative pressure channel and used for attracting the film piece are further formed in the surface of one side, facing towards the mold cavity, of the mold core; the outer surface of the mold core is covered by an elastic airbag, the elastic airbag is communicated with an external air source and is used for inflating and pressurizing so as to promote the secondary attaching and shaping of the primarily attached film piece and the to-be-film-attached workpiece when the mold core is located at the first position, and a vacancy for exposing the air suction holes is formed in the elastic airbag corresponding to the air suction holes. According to the embodiment, a 3D film attaching can be realized, and the film attaching quality can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of film sticking, and in particular to a 3D film sticking device and a 3D film sticking method. Background technique [0002] With the popularization of electronic equipment, there is already a considerable market for film stickers. Sticking film, also known as beauty film and protective film, is a kind of cold lamination film that can be used to mount the surface of electronic equipment body or screen. The existing film sticking process includes manual film sticking and mechanical film sticking. Among them, manual film sticking has the disadvantages of low work efficiency, high cost, and easy to pollute the membrane; while mechanical film sticking can only achieve flat film sticking. [0003] At present, there are semi-automatic 2.5D glass inner surface bonding equipment on the market, which is used to bond tempered films with small curved surfaces, but these devices cannot bond 3...

Problems solved by technology

The existing film sticking process includes artificial film sticking and mechanical film sticking. Among them, artificial film sticking has the disadvantages of low work efficiency, high cost, and easy to pollute the membrane; while mechanical film sticking can only achieve flat film sticking

[0003] At present, there are semi-automatic 2.5D glass inner surface bonding equipment on the market, which is used to bond the tempered film with a small curved surface, but these devices cannot bond the film to 3D glass, and have the disadvantage of high defect rate of the produced products
