The cleaning motor 56 drives the pulley and cam and other components to work, and the cleaning liquid is evenly sprayed on the surface of the substrate through the extrusion cylinder 66 and the atomizing nozzle 75. At the same time, the electric heating plate 62 and the cleaning sponge 63 heat and wipe the substrate to effectively remove stains and impurities on the surface of the substrate. The height sensor 55 monitors the height of the substrate in real time to ensure that the cleaning box 52 can accurately contact the substrate. During specific operation, when the flexible substrate is transported to the bottom of the adsorption classification and cleaning mechanism 47 through the right-side transport conveying mechanism 2, the controller 5 controls the lead screw slide module 50 to run to the target position, and then the electric lifting column 51 descends, and the vacuum suction cup 54 descends and adsorbs the flexible substrate, and then the lead screw slide module 50 returns, so that the flexible substrate is placed on the horizontal plate 2 49. At the same time, the cleaning box 52 runs above the flexible substrate, and the controller 5 controls the cleaning motor 56 to drive the pulley 4 57 and the bevel gear 1 58 to rotate synchronously. The pulley 4 57 drives the pulley 5 73, the rotating shaft 3 71 and the cam 1 72 to rotate synchronously through the belt 2 74. The rotation of the cam 1 72 causes the piston push rod 69 reciprocates back and forth to perform pressurized spraying, and the detergent in the water tank 64 is sprayed onto the surface of the flexible substrate through the water supply pipe 65, the extrusion cylinder 66, the water outlet pipe 67 and the atomizing nozzle 75 in turn. At the same time, the bevel gear 58 drives the bevel gear 2, the vertical axis 60, the electric heating plate 62 and the cleaning sponge 63 to rotate synchronously, and the screw slide module 50 performs a secondary operation and movement, so that the cleaning sponge 63 rotates to clean and wipe the detergent on the surface of the flexible substrate. After cleaning, it will run in the opposite direction. The defective flexible substrate is placed on the front belt of the transport and conveying mechanism 2 on the right, and the normal flexible substrate is placed on the rear belt of the transport and conveying mechanism 2 on the right, and finally enters different classification boxes.

[0047] Beneficial effects: Improved cleaning effect: The design of the electric heating plate 62 and the cleaning sponge 63 enhances the cleaning ability and effectively removes stains and impurities on the surface of the substrate.

[0048] Enhanced system automation level: The arrangement of the electric lifting column 51, the lead screw slide module 50 and the height sensor 55 enables the system to perform adaptive adjustments according to the height and position of the substrate, thereby improving the system automation level.

[0049] Reduced cleaning costs: The automated cleaning process reduces the need for manual cleaning and reduces cleaning costs. At the same time, the efficient cleaning capability also extends the service life of the substrate.
