[0043] The controller 3 is electrically connected to the motor 44 and the driving cylinder 51 .

[0044] Working principle: First, clamp the central axes of both ends of the winding roller 1 in the two grooves 24, and pass one end of the wire harness 11 through the annular plate 27, the middle of the two wire rollers 42, and the square frame 25 in sequence.

At the same time, the baffle 43 rotates. The wire roller 42 rotates one circle and the baffle 43 rotates one circle at the same time. When the baffle 43 passes the proximity sensor 6 once, the proximity sensor 6 feeds back a signal to the controller 3 once. The length of the wire harness 11 output by the two wire rollers 42 is certain, so the controller 3 can calculate the length of the wire harness 11 output according to the number of signals fed back by the proximity sensor 6. When the length of the wire harness 11 output reaches the preset value, the control drive cylinder 51 is turned on, so that the cutting knife 52 cuts the wire harness 11. At this time, the length of the wire harness 11 cut is the required length of the wire harness.
