At the same time, the upper conveyor rack is controlled to rotate counterclockwise and the lower conveyor rack is controlled to rotate clockwise, so that the wire harness between the two conveyor racks is sent into the mounting rack, and the wire harness between the two conveyor racks is sent into the mounting rack.

After the material picking frame (2) is controlled to move to one side of the wire harness, the driving end of the first micro electric cylinder (10) inside the first movable frame (9) is used to push the movable plate (11) to approach one side of the wire harness, and then the upper and lower material picking clamps (7) are controlled to slide relative to each other by the electric slider, and the two material picking clamps (7) are used to clamp and limit the surface of the wire harness; Step a2: using the output shaft of the micro motor (6) inside the control frame (5) to control the material taking frame (2) to rotate 180 degrees between the two control frames (5), so that the material taking component on the material taking frame (2) faces one side of the fixed frame (1), controlling the driving end of the servo electric cylinder (4) to reset, and using the driving end of the first micro electric cylinder (10) inside the first movable frame (9) to push the movable plate (11) toward the inside of the material passing port (21); Step a3: the two limit plates (26) are controlled to slide relative to each other by an electric slider, and the positions of the two ends of the wire harness are detected by infrared sensors on one side of the two limit plates (26), and finally the positions of the two limit plates (26) inside the mounting frame (20) are determined, and the material removal clamps (7) on both sides are used to feed the wire harness into the mounting frame (20); Step a4: using the driving end of the third micro-electric cylinder (24) inside the upper and lower mounting blocks (22) to drive the upper and lower conveying racks (23) to approach each other, placing the wire harness between the upper and lower conveying racks (23), controlling the upper conveying rack (23) to rotate counterclockwise, and the lower conveying rack (23) to rotate clockwise, so as to deliver the wire harness between the two conveying racks (23) into the interior of the mounting rack (20); Step a5: When discharging wire harnesses of different specifications, the discharging rack (3) is controlled to rotate inside the fixed rack (1) through the coordinated transmission of the servo motor (17), the driving gear (18) and the driven gear (19), so that the other mounting rack (20) is located on one side of the feed port (15), and the two limit plates (26) inside the mounting rack (20) are used to limit the discharging specifications of the wire harnesses, and then the upper and lower conveying racks (23) are used to feed the wire harnesses into the mounting rack (20); Step a6: After a certain number of wire harnesses are stored between the upper and lower conveying racks (23), the mounting rack (20) is controlled to rotate to above the discharge port, and the two conveying racks (23) are driven in reverse to deliver the wire harnesses inside the mounting rack (20) through the blanking rack (16). The wire harnesses delivered through the blanking rack (16) are all of the same specification.
