Description

Technical Field

[0001] The utility model belongs to the technical field of film pasting on glass cover plates, and in particular relates to a film pasting device for a mobile phone camera glass cover plate. Background Art

[0002] Mobile phones are usually equipped with cameras to realize the photo function. As people's requirements for photo effects become higher and higher, the number of cameras on existing mobile phones is increasing, from single-camera, dual-camera to triple-camera, quad-camera, and the glass cover plate covering the rear camera is also getting larger. When processing this type of glass cover plate, in addition to size processing, it is often necessary to perform coating, etching and other processing. To ensure the processing effect, the glass cover plate needs to be cleaned and a protective film is affixed before processing to avoid secondary contamination of the surface to be processed of the glass cover plate. There are two traditional film pasting methods. One is to directly unfold the roll film and paste it on multiple glass cover plates, and then cut it into single pieces. This method can ensure that the surface to be processed of the glass cover plate is completely covered, but it is easy to damage the edge of the glass cover plate when cutting it into a single piece. The other is to cut out a single piece of film first, and then paste it on the glass cover plate. This method does not require subsequent cutting steps, but it is difficult to align during pasting, and it is easy to expose the surface to be processed of the glass cover plate due to the crooked film, resulting in poor protection effect.

Similarly, the adsorption table 25 is also provided with an avoidance groove for avoiding the finger plate 322.

[0034] Since some models of glass cover plates have back films pasted on them before film pasting, these back films need to be removed during unloading to facilitate subsequent processing.

Specifically, the back film tearing unit 58 includes a temporary placement table 581, a movable film tearing seat 582, and a film tearing clamp 583 rotatably connected to the film tearing seat 582.

The moving direction is the same as that of the film tearing seat 582, and the rack 588 keeps meshing with the gear 587. When the driving cylinder 589 is actuated, the meshing of the rack 588 and the gear 587 can drive the clamping cylinder 584 to rotate, so that the film tearing clamp 583 simulates the human hand action to tear off the back film of the glass cover plate on the temporary placement table 581. After the back film is torn off, the unloading suction head 53 sucks it up again and transfers it to the unloading tray 56. The back film torn off from the film tearing clamp 583 is discarded into the waste frame 590.

[0036] In this embodiment, the tray conveyor belt 57 is used to convey the lower tray 56. A lifting plate 571 capable of lifting the lower tray 56 is provided at the end of the tray conveyor belt 57.
