After the discharge chute 206 is installed, two wires 5 to be crimped and peeled are placed in the feeding housings 209 by the robot intermittently, so that the wires 5 fall into the discharge chute 206 along the positioning plate 210. Meanwhile, the cylinder 301 is started, the extending end of the cylinder 301 pushes the sliding plate 302 to slide on the bottom plate 1, the driving plate 303 fixedly installed on the sliding plate 302 also moves, so that the first inclined surface 304 on the driving plate 303 and the second inclined surface 307 on the vertical rack 306 slide relatively, the vertical rack 306 is pushed upwards through the driving plate 303, the guide rod 308 fixedly installed on the bottom plate 1 in the process plays a guiding role, the first return spring 309 is compressed, the first return spring 309 is used for assisting in resetting of the vertical rack 306, the vertical rack 306 is meshed with the transposition gear 208, the transposition gear 208 rotates, the transposition gear 208 forms ratchet pawl matching with the central shaft 203, the central shaft 203 can be driven to rotate in the process of moving upwards through the vertical rack 306, the central shaft 203 is fixedly connected with the transposition wheel 202, the transposition wheel 202 rotates inside the shell 201, the material discharging groove 206 is sequentially rotated below the feeding shell 209, and accordingly the material discharging groove 206 loaded with the material wire 5 is sequentially rotated to the position of the material feeding through hole 207. It should be noted that, during the upward movement of the vertical rack 306, the feeding rack 305 does not move below the feeding gear 310, that is, the feeding gear 310 is not engaged with the feeding rack 305, when the discharging slot 206 loaded with the wire 5 moves to the position of the feeding through hole 207, the horizontal plane above the driving plate 303 moves below the vertical rack 306, at this time, the vertical rack 306 is not lifted any more, and the transposition wheel 202 is not rotated any more.

After the crimp terminal 6 and one end of the wire 5 move onto the crimp table 404, a power motor 411 fixedly mounted on the bottom plate 1 is started, so that an output shaft of the power motor 411 drives a rotating shaft 412 to rotate on the bottom plate 1, the rotating shaft 412 drives a belt assembly I410 and a belt assembly II 413 to rotate through belt assemblies II 413 and belt assembly I410, the rotating belt assembly I410 rotates a threaded rod 405, the threaded rod 405 is in threaded fit with a connecting plate 408, so that the connecting plate 408 moves downwards along a return spring III 407, the connecting plate 408 which moves downwards drives a crimp block 409 to move downwards together, the crimp block 409 presses downwards the crimp terminal 6 which wraps the peeled end of the wire 5 (the part of the crimp terminal 6 provided with an arc is shown as the left end of the crimp terminal 6 in fig. 15), and thus the two crimp blocks 409 finish crimping the crimp terminal 6 and the two crimp blocks; in the process that the connecting plate 408 drives the crimping block 409 to move downwards to finish crimping, the belt assembly II 413 drives the material taking gear 414 to rotate, the material taking gear 414 is meshed with the material taking rack 415, the material taking rack 415 is fixedly connected with the horizontal rod 416, so that the horizontal rod 416 is in sliding fit along the straight rod 417, the clamp 418 on the horizontal rod 416 is close to the crimping terminal 6, after the crimping block 409 completes crimping of the left end of the crimping terminal 6 with the wire 5, the clamp 418 just moves to the right end of the crimping terminal 6, and thus the right end (as shown in fig. 15) of the crimping terminal 6 is inserted into the clamp 418 (the crimping block 409 presses the crimping terminal 6, so that the clamp 418 clamps the crimping terminal 6 and the crimping terminal 6 cannot move), and the fact that the clamp 418 comprises an upper clamping piece and a lower clamping piece is rotationally connected, and a spring is arranged between the two clamping pieces is not repeated in the prior art.
After the right end of the crimp terminal 6 is inserted between the two jaws of the clip 418, the output shaft of the power motor 411 is reversed, the connection plate 408 and the crimp block 409 are moved upward, and the take-out rack 415 and the horizontal bar 416 are moved to a side away from the crimp block 409, but at this time, the clip 418 clips the crimp terminal 6 and the two wires 5 are crimped, so the clip 418 drives the crimp terminal 6 and the two wires 5 to move together, so that the portion of the two wires 5 left in the discharge groove 206 is drawn out (at this time, the cylinder 301 can be started, the transposition wheel 202 is rotated continuously, and the wire 5 to be crimped next is rotated to the feed through hole 207).
During the return of the clamp 418 to the initial position, the right end of the crimp terminal 6 contacts the discharge bar 419 fixedly installed on the supporting table 421, and at this time, the discharge bar 419 blocks the crimp terminal 6, so that the crimp terminal 6 is separated from the clamp 418, and then the clamp 418 returns to the initial position, and the crimp terminal 6 separated from the clamp 418 is dropped into the collection box 420 under the discharge bar 419 with the two wires 5 to complete the collection. The discharge lever 419 is located below the clip 418 so as not to interfere with the movement of the clip 418.
