[0069] Such as figure 1 , 2 As shown, the working principle of the present invention is as follows:

[0070] (1) The raw material cable 100 is wound in a disk shape and supplied to the splitter 1. The cable 100 first passes through the splitter 1. The splitter 1 is separated from the cable 100 at a distance, and the cable 100 is cut by a blade. The cut places show that the single connecting wires are separated from each other, and the place on the flat cable 100 corresponding to the gap shows a stripping wire segment with a length of 5-7mm that still adheres to each other between the individual connecting wires; the blade set 12 cutting row When the string 100 is reset upwards, the pressing plate 16 is turned over, and the pressing plate 16 turns over with the pressing wheel 17, and finally the pressing wheel 17 is pressed on the cable 100 being conveyed, and the pressed part of the string is bent into the arc groove 18, Due to the directional conveyance of the wire feeder 2, the pressing wheel 17 can only pull the rear cable 100 forward for a short distance, so that after the blade set 12 cuts the cable 100, the cable 100 stuck on the knife holder 13 can be Loosen, reduce the resistance when sending the wire later;

[0071] (2) The cutting machine 3 cooperates with the shaping machine 4 to cut and shape the cable 100 into a cable segment with both ends flush and horizontally aligned with the reclaiming platform 81; the front end of the cable 100 is sequentially sent to the first crimping mechanism and The second crimping mechanism, because the protrusion 418 of the shaping block 412 faces the crimping mechanism 41, and the distance W between the protrusion 418 and the inner surface of the crimping mechanism 41 is the width of the flat cable 100, during the advancement of the flat cable 100 If the flat cable 100 deviates, the flat cable 100 will be obstructed by the bump 418, and the forward trajectory of the flat cable 100 will be corrected to achieve the purpose of making the two ends of the flat cable 100 horizontal; the front end of the flat cable 100 passes through the first pressure After the wire mechanism is conveyed to the second wire pressing mechanism and pressed, the wire feeder 2 continues to convey to the shaping machine 4 according to the required cutting length, the lifting rod 422 rises freely, and the middle part of the cable 100 rises following the lifting rod 422 to feed the wire After the machine 2 has fed the cable 100 of the specified length, the first pressing mechanism presses the cable 100, and the lifting rod 422 stops rising. At this time, the stripping cable segment on the cable 100 is just under the cutting knife 32 of the cutting machine 3. The cutting machine 3 cuts in the middle of the stripping cable segment to obtain a cable segment of a specified length. The two ends of the trimmed cable segment are still glued together to make the two ends of the cable segment flush;

[0072] (3) The platform driving mechanism 83 drives the reclaiming platform 81 to the shaping machine 4 along the track 82. When the reclaiming platform 81 moves to the first track 821, the turning mechanism 811 is turned over, the reclaiming clamp 812 is turned over 90°, and the two picking The material clips 812 correspond to the two crimping mechanisms 41, the upper clamping arm 812a of the reclaiming clip 812 is aligned with the upper groove 415 of the pressing block 414 of the crimping mechanism 41, and the lower clamping arm 812b of the reclaiming clip 812 is aligned with the crimping line The telescopic block 418 of the carrying platform 417 of the mechanism 41, the lower clamping arm 812b of the reclaiming clip 812 before entering the crimping mechanism 41 acts on the inclined block 413 of the shaping block 412 to move the shaping block 412 downward, and then the reclaiming clamp 812 The upper clamping arm 812a extends into the upper groove 415 of the pressing block 414, and the lower clamping arm 812b pushes the telescopic block 418 of the load-bearing platform 417 into the load-bearing platform 417. At this time, the two ends of the cable segment in the crimping mechanism 41 are respectively in two positions. Between the upper clamping arm 812a and the lower clamping arm 812b of the side picking clip 812, the clip drive mechanism drives the picking clip 812 to move, the line pressing mechanism 41 and the lifting mechanism 42 are reset, and the picking clip 812 removes the cable segment from the shaping machine 4 Take it out, and after taking it out, the shaping block 412 will automatically reset under the action of the spring;

[0073] (4) The platform driving mechanism 83 drives the reclaiming platform 81 to the wire stripping machine 5, and the wire stripping machines 5 distributed on both sides of the rail 82 strip the two ends of the cable segment on the reclaiming platform 81 into bare wires;

[0074] (5) When the reclaiming platform 81 moves to the second track 822, the turning mechanism 811 on the reclaiming platform 81 is reset and the two ends of the originally horizontal cable segment are folded upward to 90°;

[0075] (6) The folded ends of the cable segment respectively enter the shaping slot 615 of the wire feeding mechanism 61 of the terminal crimping machine 6 on both sides of the rail 82, and the two ends of the cable segment are detected by the photoelectric sensor before entering the shaping slot 615 And start to calculate the distance, when the first connecting wire of the cable segment reaches the blocking block 6111 of the cam 611, the photoelectric sensor sends a stop signal to the motor 833 that drives the screw rod 832 to stop the cable segment from conveying; the compression block drive mechanism 612 The compression block 614 is driven to move in the shaping groove 615, and the two ends of the cable segment are pressed backward. The first connecting line in the cable segment is blocked by the blocking block 6111 on the cam 611 and cannot continue to move due to the shaping groove 615 The width L is exactly the diameter of a single connecting line, so that the individual connecting lines in the cable segment are closely arranged and do not overlap;

[0076] (7) Such as Figure 24 As shown, the cam driving mechanism 618 drives the cam 611 to turn over. Since the distance between the blocking block 6111 and the end of the shaping groove 615 is the same as the diameter of a single connecting wire in the cable, the cam 611 will bring out the first connection when turning over Line; the cam 611 is turned over and the single connecting line is brought out from the outlet. When the cam 611 is turned over to the limit block 6131, the cam 611 is blocked. At this time, the single connecting line is bent into a certain angle, the angle is normal It is 90°, that is, the originally vertical single connecting wire is bent horizontally to adapt to the punch of the terminal mechanism 62 for punching;

[0077] (8) Since the cam 611 is aligned with the punch of the terminal mechanism 62, after the first connecting wire is turned over to the punch of the terminal mechanism 62, the punch action presses the terminal on the bare wire end of the first connecting wire , Complete the terminal crimping;

[0078] (9) After the first connecting wire is brought out by the cam 611, the cam 611 is reset, and the platform driving mechanism 83 drives the reclaiming platform 81 to step by a distance equal to the diameter of the single connecting wire, and the second connecting wire is in place, and so on. Operate until both ends of all single connecting wires in the cable segment are crimped.

[0079] (10) The material conveyor 8 conveys the cable segment after the terminal crimping to the unloader 7. After the unloading clamp 73 on the unloader 7 receives the cable segment on the unloading clamp 812, the motor 71 drives the turning plate 72 Turn over, the discharge clamp 73 releases the cable segment, so that the cable segment automatically falls into the collection box, completing the entire terminal crimping process.

[0080] The wire splitting machine 1, the cutting machine 3, and the shaping machine 4 of the present invention cooperate with each other to complete the cutting and finishing of the cable. The material conveyor 8 sends the trimmed cable segment to the wire stripping machine 5 and the terminal crimping machine 6 for processing, and finally The terminal crimping at both ends of the cable segment is completed, and the whole process is automated, with high production efficiency and convenient operation.
