Then, the leveling module 31 drives the leveling bar 32 to move, and the side leveling cylinder 33 drives the side leveling plate 34 to move, so as to level the stacked PCB board products from both sides. After the leveling is completed, the baffle cylinder 36 drives the lifting baffle 35 to descend, and the leveling bar 32 and the side leveling plate 34 are separated; then, the sliding module 41 of the clamping and transporting mechanism 4 drives the sliding frame 42 to move, and the screws of the forward and reverse screw modules 43 drive the two U-shaped frames 44 are separated; then the first displacement module 6 drives the connecting plate 7 to move horizontally, so that the cable tie machine 8 is aligned with the end of the first conveyor line 2, and the gantry at the upper end of the cable tie machine 8 is located between the two U-shaped frames; then the lifting cylinder 45 drives the material moving plate 46 to descend, and the forward and reverse screw modules 43 drive the two U-shaped frames 44 to move closer, so that the two material moving plates 46 clamp the stacked PCB board products, the lifting cylinder 45 drives the material moving plate 46 to rise, and the sliding module 41 drives the sliding frame 42 to move, and the stacked PCB board products are moved to the cable tie machine 8, and the cable tie operation is automatically performed; after the cable tie in one direction is completed, if the PCB board products need to be For bundling in another direction, the second displacement module 11 drives the carrier plate 12 to move, so that the steering mechanism 13 approaches the cable tie machine 8, and the clamping and transporting mechanism 4 moves the PCB board product from the cable tie machine 8 to the steering fixture 133 of the steering mechanism 13; the servo motor 132 is energized to drive the steering fixture 133 to rotate a specific angle to achieve steering, and then the clamping and transporting mechanism 4 moves the PCB board product from the steering fixture 133 of the steering mechanism 13 to the cable tie machine 8 to perform the cable tie operation in the other direction; after the cable tie operation is completed, the second displacement module 11 drives the carrier plate 12 to move, so that the variable-length streamline mechanism 14 approaches the cable tie machine 8, and the clamping and transporting mechanism 4 moves the PCB board product from the steering fixture 133 of the steering mechanism 13 to the cable tie machine 8, and the cable tie operation in the other direction is performed.
