And a second step of: after the wire harness is transported and clamped from the jig plate, the clamping jaw mechanism needs to carry the wire harness to move to a station of the riveting machine for riveting, so that the turnover assembly and the translation assembly connected through the clamping jaw mechanism drive the wire harness to translate and turn over to adjust angles, after the clamping jaw mechanism moves to a designated position, a plurality of groups of side-by-side wire clamping structures need to stretch out in sequence, the wire harness is sequentially sent to the riveting station of the riveting machine for riveting, and the action principle of the sequential stretching out is the same as that of the wire harness clamping.
And a third step of: the two wire harnesses are butted, the two wire harnesses are directly required to be butted in riveting, because the first wire harness is clamped through the first clamping jaw a and the second clamping jaw b in a matched mode, and the second wire harness is clamped through the third clamping jaw c and the fourth clamping jaw d in a matched mode, when the first wire harness is butted with the second wire harness, the first clamping jaw a and the second clamping jaw b are controlled to synchronously translate inwards, the third clamping jaw c and the fourth clamping jaw d are controlled to synchronously translate inwards, so that the two clamping jaws can be close to each other, the end portions of the two wire harnesses are provided with a butt joint point, and then riveting is carried out on the butt joint point through the riveting machine.
Fourth step: the wire harness sleeve is characterized in that the sleeve which needs to be sleeved on the riveting point is sleeved on the wire harness in other modes before riveting, so that after riveting of the two wire harnesses is completed, the first clamping jaw a and the third clamping jaw c are controlled to translate outwards, meanwhile, the second clamping jaw b and the fourth clamping jaw d are kept stationary, when the first clamping jaw a and the third clamping jaw c move outwards to abut against the sleeve on the wire harness, the first clamping jaw a and the third clamping jaw c stop moving outwards and start moving inwards with the sleeve, and the sleeve moves to the riveting position of the two wire harnesses, so that the sleeve at the riveting position is completed.
And fifthly, performing thermal shrinkage on the wire harness, and after the wire harness completes the sleeve work, enabling the clamping jaw mechanism to move to a thermal shrinkage station to perform thermal shrinkage with the wire harness through the cooperation of the overturning assembly and the translating assembly.
