The limiting component 31 is mainly used for fixing the wire harness, because when the wire harness is processed, the wire harness needs to be twisted and pressed into a lantern shape, and one end of the part of the wire harness to be processed needs to be kept motionless, wherein motionless means that the part of the wire harness is neither rotated nor moved. When the twisted wire assembly 22 twists the wire harness, one end of the wire harness needs to be kept still, so the limiting assembly 31 is used for clamping the critical positions of the non-processing end and the processing end of the wire harness to be processed, then the twisted wire assembly 22 starts twisting the wire harness, the twisted wire assembly 22 twists for the first time according to the winding direction of the wire harness, if the wire harness is wound clockwise, the wire harness is twisted clockwise, namely, the wire harness is pre-tightened in the original winding direction, if the wire harness is not pre-tightened, the wire harness is directly twisted anticlockwise, and when the wire harness has a scattering sign, the wire harness is twisted anticlockwise, so the wire harness is twisted into the wound wire harness in the other direction again, and the wire harness is not opened, so the wire harness needs to be pre-tightened firstly, and then the wire harness is twisted in the.

The parallelogram motion track of the wire clamping assembly 7 is specifically as follows: when the device moves, the second linear cylinder 7331 is driven to drive the wire clamp clamping jaw to perform rough adjustment on one position, so that the wire clamp clamping jaw moves to the position right below the wire harness and is close to the vertical direction of the wire harness, then the first linear cylinder is driven to move vertically upwards to drive the wire clamp clamping jaw to drive the wire clamp 71 to penetrate into the interval of wires, and the pneumatic clamping fingers 72 close the clamping fingers to enable the wire clamp 71 to clamp the wires; then, the second linear cylinder 7331 is driven to move obliquely downward, the target wire is drawn out, and then the second linear cylinder 7331 moves downward, completely drawing down the drawn wire to be separated from the wire harness.

The specific operation and control of the wire clamping part comprises the following steps:

driving a second linear cylinder 7331 to drive the power platform to move obliquely upwards until the wire clamp 71 on the power platform moves to a position right below the wire harness to be processed;

the first straight line cylinder 7322 is driven to drive the power platform to vertically move upwards until the left clamping piece 711 and the right clamping piece 712 of the wire clamp deeply penetrate into the wire bundle;

the power platform drives the left clip 711 and the right clip 712 to clamp the wire;

driving the second linear cylinder 7331 to drive the power platform to incline downwards and drive the wire clamp 71 to pull out the clamped wire;

actuating the first linear cylinder 7322 to move the power platform vertically downward and the wire clamp 71 to separate the wire from the wire bundle;

and the power platform drives the wire clamp to open to obtain the wire.

The device further comprises a recognition device 9, wherein the recognition device 9 is arranged on the wire clamping base 5, and the recognition device 9 is used for recognizing the position of the wires pressed into the lantern-shaped wire bundle.

The specific operation is as follows: when the wire harness is pressed into the lantern shape, the wire clamping portion starts to clamp the wire harness, but in order that the wire clamp 71 does not go wrong (clamp wrong wire), the identification device 9 is required to identify the wire harness and then operate the power assembly 73 to move the wire clamp 71.

The specific operating principle of the identification means 9 can be seen in the patent application CN 110246156A.
