Then cylinder 2 11 is closed, driving the first jaw group 12 to hold the wire. By setting a limit bolt 13 on the first jaw group 12, it is avoided that the jaws hold the wire too tightly, enabling the wire to slide freely within the jaw closing channel and preventing it from bending up and down; cylinder 6 18 is opened, and the front output shaft of cylinder 6 18 pushes open the carrier wire clamp 23 on the carrier substrate 20, releasing the restraint and positioning of the wire inside the V-shaped groove 22. Cylinder 4 16 is opened, and the front end of the output shaft of cylinder 4 16 extends out, contacts the wire end, and pushes the wire forward by a certain distance d1; then cylinder 3 14 is closed, driving the second jaw group 15 to wrap around and clamp the wire. Cylinder 4 16 is closed, causing the front output shaft of cylinder 4 16 to disengage from the contact with the wire tail end. Cylinder 5 17 is closed, driving the second jaw group 15 and the already clamped wire to move backward by a certain distance d2. The magnitudes of the two distances can be adjusted according to actual requirements; by setting a limit screw 26 and a buffer 27 on the side plate 7, the movement amount after cylinder 5 17 is opened is restricted, ensuring the accuracy of the position of the second jaw group 15 after cylinder 5 17 is opened and ensuring the accuracy of d2; d1 is obtained by using the full stroke of cylinder 4 16 to ensure the accuracy of d1; the accurate position of the wire end face is obtained through the cooperation of cylinder 5 17 and cylinder 4 16; cylinder 6 18 is closed, and the output shaft of cylinder 6 18 retracts, and the carrier wire clamp 23 is bounced back by the return spring 25 to re-fix and hold the product tightly in the V-shaped groove 22; thus, the positioning of the wire end face is completed; cylinder 2 11 and cylinder 3 14 are opened respectively, driving the first jaw group 12 and the second jaw group 15 to open respectively, releasing the fixed restraint on the wire. Then cylinder 1 8 is closed, driving the movable plate 4 to rise as a whole. Cylinder 5 17 is opened, making the whole return to the initial state, and the work is cycled in sequence.
