secondly, in the process of the first step, after the second sealing pressing plate (31) is completely contacted with the edge of the LED display screen, the dust layer (44) on the roller shaft (43) is contacted with the surface of the LED display screen, in the process of pressing down after contact, the equipment frame (37) rotates on the U-shaped block (34), the reset spring (36) is pulled when the limiting shaft slides in the arc-shaped groove (35), so that the dust layer (44) is more fully contacted with the display screen, in this way, dust on the display screen (11) can be completely removed, in the process of continuous pressing down, the alcohol micro-infiltration cotton strip (46), the smearing layer (18) and the glue coating shaft (42) are sequentially contacted with the display screen, when the electric sliding rail (33) is started, the electric sliding rail (33) moves towards the right side, in the process, the dust on the display screen (11) is completely removed and adhered by the dust layer (44) in the rolling process, alcohol is smeared on the display screen by the alcohol micro-infiltration cotton sliver (46), so that spots of solidified glue on the display screen (11) are wiped cleanly, dust attached with static electricity on the surface is removed, dirty spots on the display screen can be cleaned cleanly by wiping of the wiping layer (18), the wiping shaft (42) wipes a glue film on the cleaned display screen, the wiped glue film is scraped by the wiping plate (41), the air is supplied into the heat dissipation sleeve (40) by the fan machine (22) on the fan set (21), the air passes through the heat dissipation sleeve (40), and the discharged hot air can dry the glue to form a coating layer;
a third step; in the second step, when the adhesive film is dried, external air flow passes through the dust hood (23), the air flow enters the hollow cylindrical sleeve (231) from the air inlet (234) and flows in a spiral cavity formed by the spiral plate (232), air in the flowing process is in surface contact with the non-dry adhesive layer (233) coated, the inner side and the outer side of the spiral plate (232) can be in contact with the non-dry adhesive layer (233) coated to stick dust in the air flow, and when the air flow passes through the plurality of square frames (2361), under the action of the air flow, when the air flow passes through the screen plates (2364) of the two mounting frames (2363), the two screen plates (2364) are close to each other, so that the flow rate of the air flow can be adjusted, the dust in the air flow can be thoroughly removed, and the cleanness of the coated surface is guaranteed;
the fourth step; when glue is smeared, when a booster pump (26) sends inner glue water of a glue water tank (25) to the inside of the hollow sleeve (423), the glue flows to the hollow square glue outlet channel (425) from the inside of the glue outlet channels (424) and flows to the inside of the fixed sleeve from the inside of the hollow square glue outlet channel (425), when the arc-shaped sponge (4214) is in contact with the display screen (11), the connecting seat (4213) moves towards the axis of the fixed sleeve under the action of pressure, the sealing strip (428) extrudes the pressing spring (4210), a gap is formed between the strip-shaped rod (427) and the strip-shaped groove (426), the glue inside can flow to the arc-shaped sponge (4214) from the gap, the glue seeps out from the gap (4212), the arrangement can increase the uniformity of the glue, the condition of a cavity cannot occur when the glue film is formed, and the integral forming of the film is ensured.
