[0066] S2, dust collection: during the movement of the dust removal cotton 422, the front section rod of the segmented independently controlled electric telescopic rod 411 is controlled to extend, so that the two U-shaped plates 40 are driven to approach each other, so that the screen printing screen 47 squeezes the clamping plate 41 to move, and the clamping plate 41 on the left side pushes the first piston plate 44 to move, so that the pressure in the inner cavity of the shell 42 on the left side increases, and the gas in the inner cavity of the shell 42 is discharged through the first one-way air outlet valve 424, the clamping plate 41 and the air outlet hole 423, and the front section rod of the segmented independently controlled electric telescopic rod 411 is controlled to contract, so that the U-shaped plate 40 returns to its original position, and the clamping plate 41 and the first piston plate 44 return to their original position under the tension of the first spring 46. During the return of the first piston plate 44, the first one-way air inlet valve 426 is opened, so that the floating dust on the texture screen printing device machine 1 enters the inner cavity of the collection screen frame 425 along with the gas through the first one-way air inlet valve 426, so as to collect the dust;

[0067] S3, disassembling the collection net frame 425: by operating to bring the two U-shaped plates 40 closer to each other, push the clamping plate 41 to move, the clamping plate 41 drives the piston rod 45 and the first piston plate 44 to move, so that the first piston plate 44 drives the push plate 434 to move, the push plate 434 drives the special-shaped plate 432 to move through the second inclined plate 433, the special-shaped plate 432 drives the L-shaped card plate 429 to move, so that the L-shaped card plate 429 is separated from the slot 428, and the pull rod is pulled to drive the collection net frame 425 to move, and it is pulled out and disassembled to dump the dust;

[0068] S4, loading: place the mobile phone back cover film on the material support table 3, control the middle section of the segmented independently controlled electric telescopic rod 411 to retract, so that the driving rod 416 moves to the inner cavity of the second spiral groove 418, so that the U-shaped plate 40 rotates in the opposite direction by 90 degrees, so that the suction port of the suction cup 43 on the right side faces downward, and the suction cup 43 is driven to move rightward to the top of the mobile phone back cover film by controlling the operation of the first linear motor 419. Through operation, the two U-shaped plates 40 are brought close to each other, and the right side of the screen printing screen 47 pushes the right clamping plate 41 to move, and the right clamping plate 41 pushes the right side through the piston rod 45.

By controlling the operation of the first linear motor 419 and the second linear motor 420, the suction cup 43 and the back cover film of the mobile phone are driven to move to the texture screen printing device platform 1 for screen printing processing;

[0069] S5, silk screen processing: through the second linear motor 420, the silk screen screen 47 is driven to move downward, so that the silk screen screen 47 covers the top of the back cover film of the mobile phone, and the third linear motor 50 is driven to move the flat plate 51, the vertical plate 52 and the scraper 55 to the right side, and the electric push rod 526 is controlled to contract, so as to drive the second piston plate 517 and the spring telescopic rod 521 to move backward, and the spring telescopic rod 521 on the rear side moves to contact and squeeze the reverse threaded protrusion 520, so that the gear roller 512 rotates in the opposite direction, and the gear roller 512 drives the right side convex plate 515, the vertical plate 52, the mounting tube 53 and the scraper 55 to move downward (the gear roller 512 will not drive the left side convex plate 515 and the vertical plate 52 to move upward during the reverse rotation), so that the scraper 55 contacts the silk screen screen 47, and then the third linear motor 50 is driven to move the scraper 55 to the left, and the scraper 55 scrapes the silk screen screen The plate 47 makes the bottom of the screen printing screen plate 47 closely contact with the rear cover film of the mobile phone, and the texture screen printing is performed on the rear cover film of the mobile phone. After the screen printing is completed, the electric push rod 526 is controlled to extend, so that the second piston plate 517 drives the spring telescopic rod 521 to return. During the return process of the spring telescopic rod 521 on the rear side, the inclined surface 522 contacts and is squeezed with the reverse thread protrusion 520 to prevent the gear roller 512 from rotating forwardly. When the spring telescopic rod 521 is separated from the reverse thread protrusion 520, the fourth spring 516 pushes the vertical plate 52 to return, so that the scraper 55 returns, and then the electric push rod 526 is controlled to extend, so that the second piston plate 517 drives the front spring telescopic rod 521 to move forward and contact with the positive thread protrusion 519, so that the gear roller 512 rotates forwardly, so that the ink return knife 54 on the left side moves downward and contacts with the screen printing screen plate 47, and the ink return knife 54 moves to the right through operation to perform the ink return operation, and the cycle is repeated;

[0070] S6, drying: After the screen printing of the back cover of the mobile phone is completed, the driving rod 416 is moved into the second spiral groove 418 by controlling the operation of the segmented independently controlled electric telescopic rod 411, so that the U-shaped plate 40 drives the third linear motor 50, the flat plate 51 and the air outlet hood 57 to rotate 180 degrees, so that the air outlet hood 57 rotates downward, and the air in the cavity of the gear roller 512 is heated by controlling the heating ring 518 to extend the electric push rod 526 to drive the second piston plate 517 to move forward, so that the second one-way air outlet valve 511 is opened, and the air in the cavity of the gear roller 512 is heated. The hot air passes through the second one-way air outlet valve 511, the first telescopic hose 510 and the air outlet hood 57 in sequence, and blows toward the surface of the rear cover film of the mobile phone to dry the silk-screen texture. When the second piston plate 517 moves backward, the second one-way air inlet valve 524 opens, and the external air enters the inner cavity of the gear roller 512 through the second one-way air inlet valve 524 and the second telescopic hose 523 for replenishment. The cycle is repeated. After drying is completed, the suction cup 43 rotates downward to absorb the left edge of the top of the rear cover film of the mobile phone, move it to the conveyor belt 2, and then transport it to the next step for processing.
