[0039] The working method of the automatic feeding and reflux device for cables of the present invention includes the following steps:

[0040] S1. Initially, the cable conveying carrier 2 is located at the position of the cable feeding unit 3, and the cable conveying carrier 2 is directly below the limit head 363.

[0041] S2. The cable feeding unit 3 starts to work:

[0042] S2-1. The piston rod of the limit driving cylinder 361 retracts, driving the limit head 363 to insert into the through hole two 231 until the limit head 363 reaches the designated position.

[0043] S2-2. The piston rod of the pressing driving cylinder 33 extends, driving the limit head 363 to press down. The limit head 363 contacts the rectangular convex portion 242, and the limit head 363 presses down the cable clamping block 24, and the return spring 25 is compressed. Since the rectangular convex portion 242 moves downward, the cross-sectional area of the cable placement groove 241 located in the through hole one 221 increases.

[0044] S2-3. Manually insert one end of the cable into the cable placement groove 241, and make the end of the cable in the cable placement groove 241 abut against the limit head 363.

[0045] S2-4. The piston rod of the pressing driving cylinder 33 retracts, causing the limit head 363 to move upward, releasing the pressing on the rectangular convex portion 242. The return spring 25 resets and pushes the cable clamping block 24 upward, so that the cross-sectional area of the cable placement groove 241 located in the through hole one 221 decreases, and the cable is clamped between the cable placement groove 241 and the M-shaped limit plate 22, thus completing the clamping and feeding of the cable.

[0046] S3. As the end carrier displacement unit 9 pushes the cable carrier 2 thereon to move, the cable carrier 2 on the cable loading unit 3 is pushed onto the loading belt conveyor 4, and the cable carrier 2 holding the cable is linearly conveyed along with the loading belt conveyor 4, and both ends of the cable carrier 2 holding the cable slide along the jig guide groove 42;

[0047] S4. The cable carrier 2 holding the cable is conveyed to the position of the jig guiding assembly 10, and the lifting drive cylinder 101 drives the guide wheel 102 to be able to contact the upper end of the M-shaped limiting plate 22, and the cable carrier 2 is guided through the guide wheel 102;

[0048] S5. The stop drive cylinder 201 drives the stop block 202 to descend, so that the distance between the lower end of the stop block 202 and the belt of the loading belt conveyor 4 is less than the height of the cable carrier 2, and the cable carrier 2 holding the cable is conveyed to the position of the stop block 202 and is stopped by the stop block 202;

[0049] S6. When the position of the cable release unit 6 is empty and there is no cable carrier 2, the stop drive cylinder 201 drives the stop block 202 to rise, and the loading belt conveyor 4 conveys the cable carrier 2 holding the cable to the position of the cable release unit 6;

[0050] S7. The cable transfer unit 5 starts to work:

[0051] S7-1. The piston rod of the transfer horizontal drive cylinder 55 extends, pushing the two symmetrical jaws of the cable gripper cylinder 57 to be in the same straight line as the cable on the cable carrier 2 at the position of the cable release unit 6;

[0052] S7-2. The piston rod of the transfer lifting drive cylinder 51 extends, pushing the cable gripper cylinder 57 to rise, so that the cable on the cable carrier 2 at the position of the cable release unit 6 is located between the two jaws of the cable gripper cylinder 57, and the jaws of the cable gripper cylinder 57 grip this cable;

[0053] S8. The cable release unit 6 starts to work: The piston rod of the pressing drive cylinder 33 extends, driving the limiting head 363 to press down, the limiting head 363 contacts the rectangular convex part 242, the limiting head 363 presses down the cable clamping block 24, and the return spring 25 is compressed. Since the rectangular convex part 242 moves down, the cross-sectional area of the cable placement groove 241 located in the through hole 221 increases, so that the cable placement groove 241 and the M-shaped limiting plate 22 release the cable;

[0054] S9. The end carrier displacement unit 9 starts to work;

[0055] S9-1. The shifting drive cylinder 82 drives the shifting slide plate 83 to move along the shifting linear guide 84 from the end of the loading belt conveyor line 4 towards the starting end of the return belt conveyor line 7. At this time, the cable is separated from the cable conveying carrier 2.

[0056] S9-2. Make the jig docking block 86 be in the same straight line as the return belt conveyor line 7.

[0057] S9-3. The piston rod of the jig pushing cylinder 85 extends, pushing the cable conveying carrier 2 on the jig docking block 86 onto the starting end of the return belt conveyor line 7.
