This allows the cable and aluminum foil to be hot-pressed without stopping, thereby improving the production efficiency of the FFC cable.

[0024] The working principle of the FFC ribbon cable aluminum foil bonding equipment provided by this utility model is as follows: When bonding FFC ribbon cables, the ribbon cable tube is fixedly sleeved on the outer surface of the ribbon cable mounting roller 4, and the aluminum foil tube is fixedly sleeved on the outer surface of the aluminum foil mounting roller 5. The outer ends of the ribbon cable and aluminum foil strip are picked up, and the ribbon cable is wound around the outer surfaces of the two guide rollers 6. Then, the aluminum foil strip is aligned with the ribbon cable and passed between the two pressure rollers 391. The outer ends of the ribbon cable and aluminum foil strip are connected to the external winding device. At this time, the pressure plates 35 are vertically adjacent to the ribbon cable and aluminum foil strip. The external nozzle sprays adhesive onto the upper end of the ribbon cable. The single-chip microcomputer 7 controls the motor 393 to operate, and the upper pressure roller 391 also rotates accordingly. Through the two gears 392 The two pressure rollers 391 rotate inward synchronously, and the external winding device also operates simultaneously, tauting the aluminum foil strip and the ribbon cable. Under the combined action of the pressure of the two pressure rollers 391 and the adhesion of the adhesive, the taut aluminum foil strip and the ribbon cable are bonded together, initially forming an FFC ribbon cable. As the FFC ribbon cable continues to move backward, the microcontroller 7 controls the left motor 37 to operate, and the right microcontroller 7 drives the left connecting piece 34 to rotate. The two connecting pieces 33 on the same side simultaneously deflect outward, driving the corresponding two clamping blocks 32 to move inward synchronously, and the pressure plate 35 also moves inward synchronously until the two pressure plates 35 clamp the FFC ribbon cable. At this time, the microcontroller 7 controls the additional... When the heating wire 36 operates, it emits high temperatures, which, in conjunction with the pressing plate 35, create a heat-pressing effect on the FFC cable. Simultaneously, after the pressing plate 35 contacts the FFC cable, the telescopic end of the right-side cylinder 38 moves backward, causing the right-side sliding frame 31 and pressing plate 35 to move backward synchronously at the same speed as the FFC cable. This movement heats the FFC cable. As the right-side sliding frame 31 and pressing plate 35 move backward, the telescopic end of the left-side cylinder 38 moves forward, causing the left-side sliding frame 31 and pressing plate 35 to move forward synchronously. Because the right-side pressing plate 35 is in a pressed state, the left-side pressing plate 35 will not touch the right-side pressing plate 35 during its movement. When the left sliding frame 31 and pressure plate 35 move forward into position, the left motor 37 starts, and the two pressure plates 35 on the left press the FFC cable together. The left heating wire 36 works, forming a heat-pressing effect on the FFC cable and moving backward synchronously. At the same time, the right motor 37 starts, and the two pressure plates 35 on the right separate. As the left sliding frame 31 and pressure plate 35 move backward, the two pressure plates 35 on the right move forward again. The two sets of pressure plates 35 alternately press the moving FFC cable and move synchronously with it. This allows the cable and aluminum foil to be pressed together without stopping, thereby improving the production efficiency of the FFC cable.
