[0029] The conveyor belt 103 is located in the middle of the side air guide 404. The hot air blown out by the side air guide 404 can enter the top and bottom of the conveyor belt 103 respectively to dry the upper and lower surfaces of the TV back panel. In order to further improve the drying effect of the TV back panel, two side air guides 404 are symmetrically arranged.
[0030] Specifically, when using this LCD TV back panel cleaning and drying device: the TV back panel to be cleaned is placed on the scraper conveyor assembly 101 inside the cleaning zone 102. At this time, the TV back panel is immersed in the cleaning fluid; the ultrasonic generator 200 is activated to emit ultrasonic waves. Under the combined action of the cleaning fluid and ultrasonic waves, the stains and impurities on the surface of the TV back panel are effectively removed; after cleaning, the TV back panel is conveyed to the bottom of the spray assembly 300 by the conveyor belt 103 of the scraper conveyor assembly 101, driven by the drive motor 105; the spray assembly 300 supplies water to the water distribution pipe 302 through an external water pump, and the water is sprayed out through the spray head 303 on the water distribution pipe 302 to perform a second cleaning of the TV back panel, ensuring a more thorough cleaning effect; after cleaning and second cleaning, the TV back panel continues to be conveyed by the scraper conveyor assembly 101 to the bottom of the drying assembly 400, and the air box 402 of the drying assembly 400 is equipped with a fan and heating wire. Air is blown in by a fan and heated by a heating wire to form hot air. The hot air flows into the air guide shroud 404 through the air duct 405 and acts on the top and side of the TV back panel on the conveyor belt 103. The conveyor belt 103 is located in the middle of the side air guide shroud 404, so the hot air blown out by the side air guide shroud 404 can enter the top and bottom of the conveyor belt 103 respectively, and perform a uniform and efficient air drying operation on the upper and lower surfaces of the TV back panel.
