[0033] In one specific embodiment of the present invention, a second fixing plate 2007 is provided at the bottom of the second stepper motor 2006. The second fixing plate 2007 is fixedly connected to the second fixing ring 2001. The fixed end of the second stepper motor 2006 is fixedly connected to the second fixing plate 2007. The output shaft of the second stepper motor 2006 passes through the outer wall of the second fixing plate 2007 and is connected to the second gear 2014 for transmission. The first fixing ring 1101 is fixedly connected to the fixing frame 1001 through the fixing block 2002.

[0034] During operation, the output shaft of the second stepper motor 2006 passes through the outer wall of the second fixed plate 2007 and is connected to the second gear 2014 for transmission, so that the rotation of the second stepper motor 2006 can drive the rotation of the second gear 2014.

[0035] The specific workflow is as follows: First, the wire harness is inserted between the two conveyor wheels 2004. Then, the first stepper motor 2005 is started. The rotation of the first stepper motor 2005 drives one of the conveyor wheels 2004 to rotate. The rotation of one conveyor wheel 2004 drives one of the first gears 2009 to rotate. The rotation of one first gear 2009 drives the other first gear 2009 to rotate. The other first gear 2009 drives the other conveyor wheel 2004 to rotate. The two conveyor wheels 2004 rotate in opposite directions. The rotation of the conveyor wheels 2004 will drive the wire harness to be conveyed downwards. When the wire harness has been conveyed to a certain length, the electric telescopic rod 1109 is activated. The push rod of the electric telescopic rod 1109 extends and drives the rotating ring 1107 to rotate. Since one end of the third slide groove 1108 is close to the rotating ring 1107, the wire harness is conveyed downwards. On the outer side of 07, the other end of the third slide groove 1108 is close to the inner side of the rotating ring 1107, so that the rotating ring 1107 rotates and drives several sliding rods 1110 to move closer or further apart. The sliding rods 1110 move and drive the slider 1104 to move. The slider 1104 moves and drives the guide wheel 1102 to move, so that the guide wheel 1102 clamps the wire harness. Then the second stepper motor 2006 is started. The second stepper motor 2006 rotates and drives the second gear 2014 to rotate. The second gear 2014 rotates and drives the third gear 2015 to rotate. The third gear 2015 rotates and drives the cutter holder 2012 and the blade 2013 to rotate, so that the blade 2013 cuts the wire harness braided mesh. After the wire harness is cut, the second stepper motor 2006 rotates in reverse. This reverse rotation drives the wire harness outward, pulling it out of the cut braided mesh. Then, the sliding rod 1110 is activated, causing several guide wheels 1102 to move away from each other, loosening the braided mesh. The first stepper motor 2005 is then activated, causing the wire harness to be fed downward again. When the wire harness core wires move to the position of the guide wheels 1102, the sliding rod 1110 is activated again, causing the guide wheels 1102 to move closer together to clamp the wire harness core wires and reduce the pressure of the guide wheels 1102 on the wire harness core wires. Finally, the camera 1007 is activated to photograph and record the position of each core wire inside the wire harness.Then, by starting the first stepper motor 2005, the wire harness continues to be fed. The wire harness cores enter the interior of the guide 1003 and are separated from each other by the limiting of the dividing plate 1011. When the wire harness cores enter the inner hole of the fourth gear 1008, they will be tightened. Then, the fifth gear 1009 is started. The rotation of the fifth gear 1009 drives the fourth gear 1008 to rotate. The rotation of the fourth gear 1008 will change the position of the wire harness cores through the dividing plate 1011, so that the wire harness cores are rotated to the correct position. Then, the wire harness cores will enter the first circular hole 1013 and change the arrangement of the wire harness cores through the connecting hole 1015, so that it changes from a circular arrangement to a rectangular arrangement corresponding to the terminal connector 1005. Finally, the wire harness cores are connected to the terminal connector 1005.
