[0024] The working principle of the automatic stripping device for automobile wiring harness disclosed by the present invention is as follows: first, one end of the wiring harness 4 is passed through the Figure 1In the three belt conveyors 103 on the right side shown, the adaptive adjustment motor 211 is controlled to rotate, and the output shaft of the adaptive adjustment motor 211 will drive the transmission pulley 210 to rotate. The rotation of the transmission pulley 210 will drive the multi-head cam 206 to rotate through the adaptive transmission belt 209 (the multi-head cam 206 is composed of three equidistantly distributed cams, and its cam edge slides with the protrusion 208). The rotation of the multi-head cam 206 will drive the second extrusion rod 207 to move along the radial direction of the second adaptive ring 205 through the protrusion 208. The movement of the second extrusion rod 207 will drive the contact sliding column 202 to move. At this time, the contact sliding column 202 can be attached to the surface of the wiring harness 4, and then the rotation of the adaptive adjustment motor 211 is stopped to fix it in the position where it stays (the rotation angle of the output shaft of the adaptive adjustment motor 211 is adjusted according to different diameters), and then one end of the wiring harness 4 is extended to the left side of the heating head 312 (as shown in FIG. Figure 4 As shown), the moving distance is controlled as needed, and then the heating head 312 is started. The heating head 312 generates heat and heats the insulation layer of the wiring harness 4 to a melted state (which can be pulled apart). Then, the stripping drive motor 316 is controlled (the stripping drive motor 316 can be started in advance). The output shaft of the stripping drive motor 316 drives the stripping drive gear 313 to rotate. The rotation of the stripping drive gear 313 drives the gear ring 305 to rotate. The rotation of the gear ring 305 drives the separation rotating frame 306 to rotate. The rotation of the separation rotating frame 306 drives the heating head 312 to rotate by adjusting the lead screw 311. Then, the heating head 312 is made to surround the wiring harness 4 for a week, melting its insulation layer, and at the same time, the rotation of the stripping drive gear 313 The rotation of the linkage input gear 314 will also drive the linkage input gear 314 to rotate. The rotation of the linkage input gear 314 will drive the input shaft of the gearbox 315 to rotate. The output shaft of the gearbox 315 will drive the output pulley 317 to rotate. The rotation of the output pulley 317 will drive the second drive pulley 323 and the first drive pulley 321 to rotate through the stripping transmission belt 319. The rotation of the second drive pulley 323 and the first drive pulley 321 will drive the corresponding claw belt conveyor mechanism 322 to rotate. The rotation of the claw belt conveyor mechanism 322 will pull the insulation layer of the wire harness 4 to move (it cannot be pulled at the beginning because the insulation layer at the position to be separated is too hard and has not melted. As it melts, the insulation layer will be pulled off by the claw belt conveyor mechanism 322, separating it from the conductive medium). When the insulation layer at the other end needs to be stripped, the wire harness 4 needs to be cut off by controlling the electric cylinder 105 and the cutting motor 106, and then it will continue to be transported to the following position. Figure 1The three belt conveyors 103 at the left end are shown, and then the steps are the same as the above steps, except that the stripping drive motor 316 only needs to be reversed when the wire harness 4 moves to the position where stripping is required, because the directions are opposite. It should be noted that the forward and reverse rotation of the heating head 312 does not affect the heating head 312 wrapping around the wire harness 4. The adjustment motor 307 is controlled as needed, and the output shaft of the adjustment motor 307 drives the adjustment driving gear 308 to rotate. The rotation of the adjustment driving gear 308 drives the adjustment nut gear 310 to rotate. The rotation of the adjustment nut gear 310 drives the adjustment screw 311 to move linearly, thereby driving the heating head 312 to move along the radial direction of the wire harness 4, so that the heating head 312 is close to the surface of the wire harness 4, and is appropriately adjusted according to the wire harness 4 of different diameters.
