[0032] The output shaft of the first motor 102 is fixedly connected to the driving wheel 103, the upper turntable 104 is rotatably arranged on the mounting frame 101, and the lower turntable 105 is rotatably arranged on the mounting frame 101. The upper turntable 104 and the lower turntable 105 are located on the same vertical line and fit each other, the automobile wiring harness passes between the upper turntable 104 and the lower turntable 105, and the driving wheel 103 is not located on the straight line where the upper turntable 104 and the lower turntable 105 are located. There are a plurality of driving rods 201, and the driving rods 201 are evenly arranged on the driving wheel 103 according to the circumference, and the driving rods 201 can move the lever 204. There are a plurality of positioning blocks 202, and the positioning blocks 202 are evenly arranged on the upper turntable 104 according to the circumference, and the support rod 203 is arranged beside the upper turntable 104, and the lever 204 can be against the support rod 203. The lever 204 is disposed between the positioning blocks 202, the lever 204 is located above the support rod 203, the buckle 205 is rotatably disposed on the lever 204, the buckle 205 has a trapezoidal cross section, with a straight surface facing upward and an inclined surface facing downward, and the buckle 205 can abut against the positioning block 202. One end of the spring 207 is connected to the support rod 203, and the other end is connected to the lever 204, and the spring 207 is in a contracted state in a natural state.

[0033] During use, the wiring harness passes between the upper turntable 105 and the lower turntable 107. Grooves for passing the wiring harness are provided on the upper turntable 105 and the lower turntable 107. The wiring harness is clamped between the grooves. In order to realize automatic feeding of the automotive wiring harness, the first motor 102 is started, and the first motor 102 drives the driving wheel 103 to rotate. The driving wheel 103 is provided with a driving rod 201. The driving rod 201 is provided with a plurality of driving rods 201. Preferably, three driving rods 201 are provided. The driving button 201 is lifted by the rotation of the driving wheel 103 to drive The movable rod 201 can move the lever 204, and the driving rod 201 lifts the lever 204, and the buckle 205 on the lever 204 is lifted synchronously, and the flat surface of the top surface of the buckle 205 abuts against the positioning block 202, thereby pushing the positioning block 202 to make the upper turntable 104 rotate through a certain angle. When the upper turntable 104 rotates, the lower turntable 105 in contact with it rotates through a certain angle synchronously, and the wiring harness in the groove is driven to move forward, and the upper turntable 104 rotates until the driving rod 201 lifts the lever 204 to no longer contact with it. When the lever 204 is lifted, the spring 207 is stretched. After the driving rod 201 is no longer exerting force, the spring 207 contracts, causing the lever 204 to return to its original position and rotate. A gap is also provided in the lever 204 to facilitate the positioning block 202 to pass through. It will not be described in detail here. When the lever 204 is reset, the positioning block 202 contacts the buckle 205 on the inclined surface, the buckle 204 can be lifted, the torsion spring 206 is twisted, and the positioning block 202 can pass through the buckle 205 and the lever 204, and the lever 204 returns to the initial position against the support rod 203. position, and then the next driving rod 201 toggles the lever 204, and the upper turntable 104 can drive the lower turntable 105 to rotate a certain angle, and the wiring harness can move forward the same distance. Through the above scheme, the wiring harness can be continuously fed with the same length; it is not difficult to see that by controlling the output of the first motor 102, the toggling speed of the driving rod 201 can be controlled, and the frequency of wiring harness feeding can be controlled, and the length of the driving rod 201 determines the angle at which the toggling lever 204 can be rotated, that is, the distance the wiring harness moves forward each time it is fed, and controls the distance that each section of the wiring harness extends.

[0034] Example 2

[0035] Reference Figures 1 to 7 , is the second embodiment of the present invention, which is different from the first embodiment in that: the output shaft of the second motor 302 is fixedly connected to the first gear 303, the first gear 303 rotates synchronously with the first turntable 305, and the second gear 304 rotates synchronously with the second turntable 306. The connecting rod 307 passes through the limit block 308, and the connecting rod 307 is slidably connected to the limit block 308. The wire groove 301 is on the same plane as the upper turntable 104 and the lower turntable 105, and the two cutters 309 can cooperate and tangent. A wire outlet groove 305a is also provided between the first turntable 305 and the second turntable 306.

[0036] Compared with Example 1, further, the wire harness also passes through the wire groove 301, which can prevent the wire harness from tilting. In order to cut the extension distance of the wire harness each time, the second motor 302 can be started, and the second motor 302 drives the first gear 303 to rotate, and the first gear 303 is meshed with the second gear 304. The first turntable 305 and the second turntable 306 are respectively connected to the first gear 303 and the second gear 304, so that the second motor 302 can drive the first turntable 305 and the second turntable 306 to rotate synchronously. Since the connecting rod 307 and the limit block 308 are slidably connected, the connecting rod 307 and the limit block 308 can only maintain a straight line between the first turntable 305 and the second turntable 3 06 rotates, that is, the extension direction of the connecting rod 307 and the limit block 308 remains unchanged. When the rotation axes of the two are close to each other, the connecting rod 307 is inserted into the limit block 308. When the rotation axes are away from each other, the connecting rod 307 is pulled out from the limit block 308, that is, the cutters 309 on the two are constantly close to each other and away from each other, so that the central wire harness can be cut. The system can be set to that when the lever 204 is reset, the cutter 309 approaches and cuts the wire harness. When the cutter 309 is separated, the lever 204 is lifted, and the wire harness moves forward the same distance again. The cutter 309 approaches and cuts, thereby entering a cycle, continuously cutting the wire harness segment, and the wire harness can fall into the wire outlet slot 305a for discharge. The discharge process will not be repeated here.

[0037] The remaining structures are the same as those of Example 1.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
