After the flexible substrate is pulled out, the flexible substrate is wound around the reel 210 on the left. After the winding is completed, the operator can start the first motor 214 through the controller 212. After the first motor 214 is started, the left shaft 211 will rotate, and then when the left shaft 211 rotates, the sleeve 208 on the upper left side will rotate. When the sleeve 208 on the upper left side rotates, The left winding rod 210 rotates, and when the left winding rod 210 rotates, the left lower sleeve 208 rotates, and when the left rotating shaft 211 rotates, the pulley 215 rotates, and then the pulley 215 rotates with the second pulley 217 through the belt 216, and when the second pulley 217 rotates, it rotates the right rotating shaft 211, and then when the right rotating shaft 211 rotates, it rotates the sleeve 208 on the upper right side, and at the same time, the sleeve 208 on the upper right side rotates with the right winding rod 210, and then the right winding rod 210 rotates with the sleeve 208 on the lower right side. When the two winding rods 210 rotate, the flexible substrate is conveyed, which is convenient for loosening and winding the flexible substrate. Later, when the flexible substrate is being transported, the operator can use the controller 212 to simultaneously start the second motor 301, the diaphragm pump 424, and the heating plate 104. After the second motor 301 is started, it will drive the roller 302 to rotate, and then the roller 302 will drive the disc 303 to rotate. When the disc 303 rotates, it will drive the fixed rod 304 to move in a circular motion. At the same time, when the fixed rod 304 moves, it will drive the second connecting rod 305 to move in an arc. Then, the second connecting rod 305 will drive the round rod 306 to move. When the round rod 306 moves, it will drive the connecting plate 307 to slide back and forth in the slide rail 308. Then, when the connecting plate 307 moves, it will drive the second fixed rod 309 to move. When the second fixed rod 309 moves, it will drive the mounting frame 310 to slide on the second round rod 314.Then, when the mounting frame 310 moves, it will move with the brush 311. When the brush 311 moves, it will clean the surface of the flexible substrate to prevent dust and impurities from adhering to the surface of the flexible substrate and affecting the subsequent coating process. Then, after the diaphragm pump 424 is started, the paint in the paint tank 421 will be extracted through the delivery pipe 423. After the paint is extracted, the paint will be transported to the bellows 425 through the diaphragm pump 424, and then the paint in the bellows 425 will be transported to the diversion pipe 426 respectively. Finally, the paint in the diversion pipe 426 will be sprayed out from the nozzle 427, and then the sprayed The coating is applied to the flexible substrate. At the same time, when the roller 302 rotates, the gear 401 rotates, and when the gear 401 rotates, the two crown gears 404 rotate. When the crown gear 404 rotates, the rotating rod 403 rotates. Then the rotating rod 403 rotates with the crown gear 2 405. When the crown gear 2 405 rotates, the gear 2 407 rotates. Then, when the gear 2 407 rotates, the transmission rod 406 rotates. When the transmission rod 406 rotates, the belt pulley 408 rotates, and the belt pulley 408 drives the belt 2 409 to rotate. As the belt pulley 412 rotates, the rolling rod 411 rotates when the belt pulley 412 rotates, and the rolling rod 411 rotates with the disk 2 413. When the disk 2 413 rotates, the circular rod 414 moves in a circular motion, and then slides in the fixed frame 417 when the circular rod 414 moves. At the same time, the circular rod 414 squeezes the fixed frame 417, causing the fixed frame 417 to move up and down. When the fixed frame 417 moves, it slides on the guide rod 420 with the mounting block 418, and the fixed frame 417 slides in the slide groove 415 with the support block 416. When the support block 416 moves, it moves with the bellows 425, which then moves with the shunt pipe 426. At the same time, the shunt pipe 426 moves with the nozzle 427, making the coating process of the flexible substrate more uniform and preventing local areas from being uncoated. After coating, the flexible substrate passes through the heating plate 104. When the heating plate 104 is turned on, the coated surface of the flexible substrate is solidified. At the same time, the coated flexible substrate is rolled up onto the left reel 210. After the reeling is completed, the operator can remove the left reel 210 from the equipment.
