A film rolling device for smart blackboard display and its working method

Abstract

The invention relates to a film rolling device for a smart blackboard display screen. A pneumatic rod is installed vertically on the top and bottom side of the top frame, and the telescopic end of the pneumatic rod is connected to a lifting seat on the outside of the top frame. A sliding seat is slidably installed on the top side of the platform, a limit seat for fixing the display screen is installed on the top side of the sliding seat, and a rolling mechanism is installed on the bottom side of the mounting seat; The rolling airbag is deformed in real time and always keeps close contact with the display screen. The film rolling operation of the display screen with different curvatures is realized by the deformation of the rolling airbag during rolling. When there is foreign matter on the display screen, the rolling During the process, the foreign matter is directly embedded in the rolling airbag, which will not cause the direct contact between the foreign matter and the rolling part and the display screen.

Description

technical field [0001] The invention relates to the technical field of smart blackboard processing, in particular to a film rolling device for a smart blackboard display screen and a working method thereof. Background technique [0002] The smart blackboard integrates traditional blackboard, large-screen display, screen touch control, OPS computer, audio, high-speed camera, Internet of Things and other related equipment. It can not only realize all the functions of the interactive integrated machine, but also use traditional chalk on the entire board surface to write. At the same time, the smart classroom teaching software, one-key recording and broadcasting and artificial intelligence system are embedded, and an external network cable and a power cord can realize all the functions of the future classroom. A protective film that acts as a protective layer. [0003] After the protective film is attached to the existing smart blackboard, the air between the protective film a...

Problems solved by technology

[0004] The problem to be solved by the present invention is to provide a film rolling device and its working method for the display screen of a smart blackboard, which solves the problem of removing the protective film by rolling back and forth on the display screen with a pressure roller after the protective film is attached to the existing smart blackboard. The air between the film and the display screen ensures that the protective film and the display screen are tightly bonded. The pressure roller is in hard contact with the protective film during the back and forth rolling process, which is easy to cause damage to the display screen during rolling. Once there are foreign objects in the rolling process Falling on the protective film, foreign matter may easily cause scratches on the protective film and the display screen during rolling; at the same time, the existing rolling device is only used for the rolling process of the flat display screen, which cannot realize the display of different specifications and different curvatures Technical Problems of Screen Film Rolling Operation
