[0022] The wire harness is passed between the upper pressing wheel 6 and the lower pressing wheel 7 of the clamping mechanism, and the beginning of the wire harness is placed at the output end of the winding mechanism. One end of the tape is manually pulled off and adhered to the beginning of the wire harness to be wound, and the wire harness is continuously pulled to move. The transmission combination of the upper pressing wheel 6, the lower pressing wheel 7 and the displacement conversion wheel 8 is used to convert the distance the wire harness moves in the discharge direction into an angle and transmit it to the encoder 9; the value on the encoder 9 is read to the motor 3 on the winding mechanism through the data file, and the motor 3 drives the tape placement component 5 to rotate to wind the tape on the wire harness. The mutual feedback between the encoder 9 and the motor 3 ensures the consistency of the winding intercept.

[0023] Specifically, the clamping mechanism also includes a mounting plate 10 and a lower clamp 11 mounted on the mounting plate 10, a linkage rod 12, a linear guide 13, a sliding plate 14 and a connecting plate 15.

[0026] The wire harness may deviate in the horizontal direction during the movement, so that the winding distance may also deviate. In order to limit the wire harness, the clamping mechanism also includes a wire harness groove 16, a crimping wheel 17, a movable block 18, a limit key 19 and a spring top column 20. The movable block 18 is hinged to the sliding plate 14. The crimping wheel 17 is installed at one end of the movable block 18, and a slide groove is provided at the other end of the movable block 18.
