[0080] The specific steps include:

[0081] a. Rubber strip grinding: the conveying device 100 conveys the rubber strip to the grinding device 200, and the surface to be taped is grinded by the grinding device 200. Specifically, the grinding cylinder 230 descends so that the grinding head 210 is attached to the surface of the rubber strip, and then the grinding motor 220 drives the grinding head 210 to rotate, and at the same time, the servo screw 710 pushes the entire grinding device 200 to move, so that the grinding head 210 grinds the surface of the rubber strip. During grinding, the air amplifier 250 works to suck the ground powder into the dust removal barrel 260 through the suction nozzle 240. After completion, the grinding cylinder 230 is reset, and then the servo screw 710 is reset.

[0082] b. Spraying xylene: The conveying device 100 conveys the rubber strip that has completed step a to the position of the xylene spraying device 310, and the xylene solution is sprayed onto the surface of the rubber strip that has been polished in step a through the xylene spraying device 310. Specifically, the spraying cylinder 303 drives the ejector-type glue spraying valve 302 and the brush 311 to descend together, and then the nozzle opens to spray out the xylene solution. At the same time, the servo screw 710 drives the xylene spraying device 310 to move, so that the nozzle sprays the xylene solution onto the rubber strip, and at the same time, the brush 311 brushes the sprayed xylene evenly. After completion, the spraying cylinder 303 is reset, and then the servo screw 710 is reset.

[0083] c. Glue spraying: the conveying device 100 conveys the rubber strip that has completed step b to the position of the glue spraying device 320, and the glue solution is sprayed onto the surface of the rubber strip sprayed with xylene in step b through the glue spraying device 320, and the defective product detection device 601 is used to check whether the glue solution is sprayed evenly. Specifically, the spraying cylinder 303 drives the ejector-type glue spraying valve 302 to descend together with the defective product detection device 601, and then the nozzle is opened to spray out the glue solution. At the same time, the servo screw 710 drives the glue spraying device 320 to move, so that the nozzle sprays the glue solution onto the rubber strip. At the same time, the defective product detection device 601 detects whether the glue solution is sprayed evenly. The one that is sprayed evenly is a good product, and the one that is not sprayed evenly is a defective product. After completion, the spraying cylinder 303 is reset, and then the servo screw 710 is reset.

[0084] d. Drying: The conveying device 100 conveys the rubber strip that has completed step c into the drying device 400, and the glue is dried by the drying device 400, and the glue solution is dried by the dryer.

[0085] e. Taping: The conveying device 100 conveys the rubber strip that has completed step d to the position of the tape sticking device 500. If the defective product detection device 601 detects that the rubber strip is good in step c, the rubber strip is stuck to the rubber strip that has completed step d through the tape sticking device 500. If the defective product detection device 601 detects that the rubber strip is defective in step c, the rubber strip directly passes through the tape sticking device 500. The tape sticking device 500 does not work. Specifically, the distance sensor 534 senses the distance of the rubber strip, and then controls the downward pressure cylinder 526 to press down so that the pressing wheel 53 1 is pressed on the rubber surface, and the tape-applying roller 525 also presses the rubber strip on the surface of the rubber strip, and the vertical pressing cylinder 512 and the inclined pressing cylinder 513 are controlled to descend so that the pressing block 514 is pressed on the rubber strip to prevent the rubber strip from moving when the tape is applied, and then the pressing cylinder 527 is descended so that the pressing roller 528 is closely attached to the surface of the rubber strip, and then the servo screw 710 drives the tape-applying device 500 to move, so that the tape-applying roller 525 is rotated by the friction force to lead out the rubber strip, and at the same time, the pressing roller 528 presses the rubber strip on the rubber strip.

[0086] When the tape roller 525 moves to the other end of the rubber strip, the rubber strip led out at this time is just equal to the length of the rubber strip. At this time, the servo screw 710 stops rotating, and then the pressing cylinder 526 rises, driving the tape roller 525 to move up, the lifting cylinder 541 descends, and then the telescopic cylinder 542 retracts, moving the two blades of the cutting knife 545 to the upper and lower sides of the rubber strip, and the cutting cylinder 543 drives the cutting blades to complete the shearing, and then the lifting cylinder 541, the telescopic cylinder 542, and the cutting cylinder 543 are reset. Finally, the servo screw 710 starts to move forward again, allowing the pressure roller 528 to press the cut rubber strip tightly against the rubber strip. After completion, the pressing cylinder 527 is reset, and then the servo screw 710 is reset.

[0087] f. Removing defective products: The conveying device 100 conveys the rubber strip that has passed step e to the position of the defective product ejecting device 600. The defective product ejecting device 600 pushes the rubber strip out of the conveying device 100 based on the detection result of the defective product detection device 601 in step c. If the product is defective, the defective product ejecting device 600 pushes the rubber strip out of the conveying device 100. If the product is good, the defective product ejecting device 600 does not work, and the conveying device 100 continues to convey the rubber strip, and the rubber strip falls from the end of the conveying device 100. Specifically, the ejecting electric cylinder 620 moves, driving the ejecting block 630 to eject the defective rubber strip from the side of the conveying device 100.

[0088] S3, storage: storing the rubber strips finished in step S2.
