Description

Technical Field

[0001] The present invention relates to the technical field of LED display production, and particularly relates to a display film laminating device and a film laminating method for processing and producing LED displays. Background Art

[0002] An LED display is a flat panel display composed of small LED module panels, and is a device for displaying various information such as text, images, and videos. After the production of a computer LED display, it often needs to be laminated on its surface to play a role in dust prevention and scratch prevention, and its protective film often has a certain thickness.

[0003] At present, most of the film laminating methods transport the LED display through a belt conveyor. After being transported to the lower part of the film laminating device, the film laminating process is automatically realized. However, the existing film laminating device can only laminate one display at a time, and generally cuts the film after laminating. In order to avoid cutting the display, the size of the protective film after cutting is often larger than the display, and subsequent trimming processes are still required, resulting in low efficiency. Summary of the Invention

[0016] 1. By setting a square cylinder, a pressing plate, a first pushing plate, a second pushing plate, and a third pushing plate are respectively installed on the four faces of the square cylinder. An adsorption mechanism is arranged on the pressing plate, and a dust removal component, a guiding component, and a film pressing component are respectively installed on the first pushing plate, the second pushing plate, and the third pushing plate.

[0017] 2. By installing multiple square blades, just starting the hydraulic cylinder can drive the multiple square blades to move downward into the corresponding square grooves on the pressing plate, so that multiple protective films of the same size as the display screen can be cut out simultaneously. Then start the air pump to inhale air, pass through the hollow shaft and the air pipe, and finally adsorb the multiple protective films on the pressing plate through multiple adsorption holes. When the pressing plate rotates to the position corresponding to the display screen, start the second cylinder to push the pressing plate downward to align and paste the protective film on the display screen. Subsequently, the air pump blows air, and the adsorption mechanism releases the protective film, enabling multiple display screens to be pasted with films simultaneously, with high film pasting efficiency and no need for subsequent trimming.

[0018] 3. By installing a guiding mechanism and a guiding component, start the first cylinder to drive the two guiding plates to move, and conduct front-to-back guiding on the display screen. When the second pushing plate rotates to the lower part, under the drive of the second cylinder, multiple abutting plates on the second pushing plate are pushed between adjacent display screens. Then start the third cylinder to push the sliding plate to move through the opening, thereby driving multiple abutting plates to push the display screen to move, and conduct left-to-right guiding on the multiple display screens, making the film pasting more accurate.

[0019] 4. By installing a dust removal component, when the first pushing plate rotates to the lower part, start the third cylinder, which can drive multiple dust removal rollers on the sliding plate to move on the surface of the display screen, thereby effectively removing the floating dust on the display screen. A film pressing component is provided. When the third pushing plate rotates to the lower part, the protective film can be rolled by multiple film pressing rollers to improve the film pasting effect.
