A dryer 205 is installed below, and is fixedly connected to the bottom wall of the frame 1. A collection box 204 is installed below the cleaning roller 202, and is slidably connected to the inner side wall of the frame 1. Extension rollers 1 206, 207, and 3 208 are installed to the right of the pressing roller 203. The cleaning roller 202, in conjunction with a sponge, uses alcohol to wipe and clean the bonding surface of the FFC, and then the dryer 205 dries it. Simultaneously, the extension rollers 1 206, 207, and 208... Long roller 3 (208) extends the evaporation time to ensure complete alcohol evaporation. Extending rollers 1 (206), 2 (207), and 3 (208) are arranged in an inverted triangular pattern. All three rollers are rotatably connected to the inner wall of frame 1. The cooperation of these rollers extends the FFC process. A loading box 209 is fixedly connected to the top of frame 1, and a replenishment pipe 210 is fixedly connected to the outside of the loading box 209. An external control valve is installed, and the replenishment pipe 210 is connected to the cleaning roller 202. Alcohol is provided to the cleaning roller 202 through the cooperation of the loading box 209 and the replenishment pipe 210. A guide roller 7 is provided on the right side of the extension roller 3 208. The guide roller 7 is rotatably connected to the inner wall of the frame 1.

[0024] Refer to the instruction manual appendix Figure 1-4Two sets of hollow telescopic columns 5 are fixedly connected to the top of the glue box 6. A glue-applying roller 8 is rotatably connected to the inner end of each hollow telescopic column 5. A spring 9 is sleeved on the inner wall of each hollow telescopic column 5. The glue-applying roller 8 contacts the FFC, causing the FFC to be coated with glue. The spring 9 ensures a tighter and more even contact between the glue-applying roller 8 and the FFC. A cleaning roller 13 is rotatably connected to the inner wall of the frame 1. A dust discharge pipe 12 is located on the lower side of the cleaning roller 13. The upper part of the cleaning roller 13... The frame 1 is equipped with a feed roller 4, which is rotatably connected to the inner wall of the frame 1.

[0025] The working principle of this practical application is as follows:

[0026] Refer to the instruction manual appendix Figure 1-4When applying a conductive layer to the FFC wire, the FFC wire is first introduced into the machine frame 1 via the feed roller 201 and cleaning roller 202. The feed roller 201, in conjunction with the pressing roller 203, brings the cleaning roller 202 and its surface sponge into contact with the FFC. Utilizing the structure of the cleaning roller 202 and the capillary effect of the sponge, the alcohol inside the cleaning roller 202 wipes and cleans the FFC as it rotates. A control valve on the outside of the replenishment pipe 210 prevents the FFC from contacting too much alcohol. The FFC is dried as it passes over the surface of the dryer 205, and then dried using extension rollers 206 and 207. 07, in conjunction with extension roller 3 208, extends the FFC process to ensure complete alcohol evaporation. Simultaneously, the conductive layer is introduced into the frame 1 through the feed roller 4, and the conductive layer is cleaned through the ash discharge pipe 12 and the cleaning roller 13. Through the cooperation of hollow telescopic column 5, glue coating roller 8 and spring 9, the FFC is coated with glue through the contact between the glue coating roller 8 and the FFC. The spring 9 makes the contact between the glue coating roller 8 and the FFC tighter and more uniform. The hollow telescopic column 5 protects the spring 9 from being corroded by the glue. Finally, the FFC and the conductive layer are bonded together inside the bonding box 10 to form an integrated whole. Finally, the material is discharged through the discharge roller 3.
