Description

Technical Field

[0001] The invention relates to the technical field of electronic product processing, in particular to an optical thin film coating device for an electronic display screen. Background Art

[0002] The electronic display screen is composed of several display units that can be combined and spliced, plus a set of appropriate controllers. Therefore, display panels of various specifications combined with controllers with different control technologies can form many kinds of LED display screens to meet the needs of different environments and different display requirements. When producing electronic display screens, it is necessary to paste optical films on the surface of the display screen. The main function of optical films is to improve the imaging effect of the display. Different types of optical films have different functions, but the most basic and common functions are to reduce reflections, prevent glare and improve the clarity of the display screen. At the same time, optical films also help to reduce the brightness of the screen and reduce stimulation to the human eye. At the same time, optical films can also protect electronic display screens to a certain extent. When pasting optical films on electronic displays, a laminating device is required for pasting.

[0003] The announcement number is: CN115042421B, which discloses an optical film coating device for an electronic display screen. The coating device adopts air pressure coating, which is more effective than traditional pressure coating. Air pressure coating can eliminate the damage to the display screen caused by external pressure, and the film can be cut and truncated by a laser cutter. However, the coating device does not have a component for pulling one end of the film, and the coating device transports the film to the display screen by arranging an emergency frame on the lead screw. After the coating is completed, the film is cut by a laser cutter. After the coating is completed, the emergency frame needs to be returned to the initial position for re-loading, and at this time, one end of the film is not pulled and limited, so that one end of the film is below the laser cutter, and the laser cutter is far away from the pressurized air nozzle, so that when the coating is performed again, The film between the pressurized nozzle and the laser cutter cannot be laminated, resulting in waste. Since there is no component for pulling and fixing one end of the film, when one end of the film is cut, the film will fall on the workbench, causing one end of the film to be contaminated. When laminating is performed subsequently, the film on the display screen needs to be cut twice, and the film on the right side of the display cannot be used due to contamination, resulting in a large amount of waste of raw materials. At the same time, when the above-mentioned laminating device removes dust before laminating the display screen, it uses a dust removal air inlet duct to transport gas into the dust removal nozzle to blow off the dust on the display screen. However, since the dust is light, after being blown away by the gas, the dust will float irregularly, so that the dust will fall on the cleaned display screen, resulting in poor dust removal effect.

[0004] Based on this, an optical thin film coating device for an electronic display screen is now provided, which can eliminate the disadvantages of the existing devices. Summary of the invention
