[0035] For this film covering equipment for processing and producing LED display screens, when in use, the user places the LED display screen on the top surface of the processing table 1, and at the same time places the protective film on the surface of the LED display screen. By providing power through the electric telescopic rod 13, during the transmission process, the film covering plate 15 squeezes the protective film placed on the surface of the LED display screen, realizing the film covering processing of the LED display screen.

The two linear motors 9 provided are used to provide power, and during the movement of the moving part of the linear motor 9, the connecting plate 4 is driven to move horizontally, so that a plurality of nozzles 8 move to the designated position to clean the surface of the LED display screen. The rotating motor 10 provided is used to provide power, and during the transmission process, it is convenient to control the angle of the gas ejected by a plurality of nozzles 8 to adapt to the ejection angle requirement of the nozzles 8 for cleaning the surface of the LED display screen. The provided limit bearing 7 fixes the rotation position of the rotating block 6 to improve the structural stability of the equipment components.
