When the upper surface of the display screen 4 is subjected to screen printing, a worker needs to place the display screen 4 on the electric transmission belt 2, then starts the electric transmission belt 2, and transmits the display screen 4 through the electric transmission belt 2, in order to ensure that the display screen 4 is completely aligned with the screen 7 when the display screen 4 moves below the screen printer 6 and the screen 7, therefore, the display screen 4 is limited by the two limiting plates 3, when the display screen 4 is transmitted on the electric transmission belt 2, the display screen 4 is fixed and limited by the two limiting plates 3 and cannot deviate due to external force, the screen printing is misplaced, meanwhile, a certain amount of cleaning water is stored at the lower side of the inner part of the water storage frame 205, a certain amount of cleaning water is stored in the inner part of the two water inlet pipes 202, a proper amount of cleaning water is absorbed in the cleaning sponge 203, and along with the transmission of the display screen 4 on the electric transmission belt 2, when the upper surface of the display screen is contacted with the cleaning sponge 203, under the extrusion action of the display screen 4, the cleaning water absorbed by the cleaning sponge 203 is automatically extruded to the upper surface of the display screen 4 to be subjected to screen printing, and then the upper surface of the display screen 4 is dedusted by the cleaning water, and under the conduction action of the cleaning water, the upper surface of the display screen 4 is simultaneously subjected to static elimination, after static elimination, the display screen 4 is ensured to be not to be re-adsorbed on the upper surface of the display screen 4 due to static elimination, dust removal and static elimination are effective to ensure the subsequent screen printing effect of the display screen 4, the screen printing is prevented from being unclear due to dust, or black spots exist after the screen printing, the influence on use is avoided, when the cleaned part of the upper surface of the display screen 4 moves to be contacted with the first water absorbing sponge 306, because the first water absorbing sponge 306 is initially in a dry state, therefore, the first absorbent sponge 306 absorbs the sewage left after the upper surface of the display screen 4 is cleaned, so as to prevent the sewage from affecting the subsequent silk screen printing, and when the display screen 4 passes through the first absorbent sponge 306, a certain friction force exists between the display screen 4 and the first absorbent sponge 306, under the action of the friction force, the first absorbent sponge 306 synchronously drives the two hollow connecting rings 305 to rotate on the second hollow sleeve column 303, namely, when the first absorbent sponge 306 absorbs the sewage left on the upper surface of the display screen 4, the first absorbent sponge 306 synchronously rotates around the second hollow sleeve column 303, thereby continuously changing the sewage absorption part of the first absorbent sponge 306, ensuring that the first absorbent sponge 306 does not lose the absorption effect because of sewage at a certain part, and as the first absorbent sponge 306 surrounds the second hollow sleeve column 303, the squeeze roller 304 synchronously squeezes the first absorbent sponge 306, the sewage absorbed in the first water absorbing sponge 306 is extruded, because the upper side of the second hollow sleeve column 303 is provided with a plurality of round holes, and the extrusion roller 304 is positioned above the second hollow sleeve column 303, the extruded sewage automatically enters the second hollow sleeve column 303 through the round holes formed on the upper side of the second hollow sleeve column 303, namely is extruded onto the guide plate 308 in the second hollow sleeve column 303, because the guide plate 308 is inclined from the middle to two sides, the sewage automatically flows into the two middle frames 302 from the guide plate 308 under the action of gravity, then flows into the water storage frame 205 from the two middle frames 302 through the two drain pipes 301, because the water storage frame 205 is separated into an upper part and a lower part which are different from each other by the separation plate 208, at the moment, the flowing sewage completely flows into the upper part of the inner side separated by the water storage frame 205, along with the increase of the sewage at the upper part of the water storage frame 205, the air pressure of the upper portion inside the water storage frame 205 is gradually increased, and under the action of the gravity of sewage, the partition plate 208 is gradually pressed downwards under the double pressing of the air pressure increase and the gravity of sewage, the partition plate 208 is pressed downwards, simultaneously, the two first elastic pieces 207 are stretched, in order to prevent the two first elastic pieces 207 from being corroded by sewage, the two first elastic pieces 207 are protected through the two protection columns 209, along with the downward movement of the partition plate 208 inside the water storage frame 205, the cleaning water at the lower portion inside the water storage frame 205 is simultaneously pressed into the two water inlet pipes 202, then the cleaning water flowing into the first hollow sleeve column 206 from the two water inlet pipes 202 is automatically absorbed by the cleaning sponge 203 due to the fact that a plurality of round holes are formed in the first hollow sleeve column 206, and further, in order to ensure that the cleaning sponge 203 continuously supplements water when the upper surface of the display screen 4 is continuously cleaned, the water is not extruded because of the water during cleaning, then gradually decreases, and at the same time, in order to prevent the upper surface of the display screen 4, the cleaning water is still absorbed by the second sponge 307, the second water is completely absorbed by the second sponge, and the display screen 4 is completely and the screen is ensured.
When the display screen 4 is cleaned and dehydrated, and is conveyed to the position right below the screen 7 by the electric conveying belt 2, under the adjustment of numerical control equipment, the electric conveying belt 2 temporarily stops working, the screen printing on the upper surface of the display screen 4 is continued to start working after finishing screen printing, the process is completed by adopting numerical control equipment, only a worker adjusts parameters, when the display screen 4 is positioned right below the screen 7, a proper amount of printing ink for screen printing is added on the screen 7 in advance, meanwhile, the screen printing machine 6 is controlled to start working, then the driving piece 408 is controlled to synchronously start working, the screen printing machine 6 is driven to move forwards from behind by the driving piece 408, different screen plates 7 are used according to different requirements, the screen printing machine 6 is enabled to print patterns consistent with the corresponding screen plates 7 on the upper surface of the display screen 4, further requirements are met, the ink on the screen 7 is automatically printed on the upper surface of the display screen 4 through the screen printing machine 6 to form a specific pattern, and the ink has certain fluidity, so that the ink automatically diffuses to the left side and the right side of the screen 7, and meanwhile, when the screen printing machine 6 moves from back to front for screen printing, in order to prevent the ink collecting plates 406 on the left side and the right side of the screen 7 from affecting the normal screen printing of the screen printing machine 6, when the driving piece 408 drives the screen printing machine 6 to move from back to front, the two connecting frames 409 are synchronously driven to move from back to front, and then one piston rod 4010 is respectively driven by the two connecting frames 409 to slide in the air rod 4011 from back to front, while sliding, the internal space of the two air rods 4011 is gradually increased, and then the internal air pressure of the two air bags 4012 is gradually reduced, namely, the internal air pressure of the two second elastic pieces 407 is gradually reduced, and because the two second elastic pieces 407 are initially in a stretched state, along with the gradual decrease of the air pressure in the two second elastic members 407, the two second elastic members 407 gradually shrink inwards, and synchronously drive the adjacent ink collecting plates 406 to rotate around the adjacent connecting rods 405 while shrinking, and the left ink collecting plate 406 rotates anticlockwise around the left connecting rods 405 based on the top-down view, and the right ink collecting plate 406 rotates clockwise around the right connecting rods 405, so that the screen printing machine 6 moves forwards from the back and simultaneously, the two ink collecting plates 406 are synchronously gradually far away from the screen plate 7, and the screen printing machine 6 is ensured not to be influenced.
When the silk screen printing of the silk screen printing machine 6 is completed, the driving piece 408 brings the silk screen printing machine 6 back to the original position, namely drives the silk screen printing machine 6 to move from front to back, further enables the two piston rods 4010 to synchronously slide from front to back in the adjacent air rods 4011, gradually restores the original position, enables the air pressure inside the two air bag balls 4012 to be gradually increased while restoring the original position, further restores the original air pressure, namely enables the inside of the two second elastic pieces 407 to gradually restore the original air pressure value, and gradually restores the original state again along with the gradual restoration of the air pressure value, and in the process of restoring the original state, ink overflowed to the left side and the right side of the screen plate 7 is gathered on the screen plate 7 again when the silk screen printing machine 6 is synchronously moved forward from back, further loss of the ink is reduced, and the silk screen printing effect is ensured.
