[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] As shown in the figure, this utility model discloses an automotive wiring harness braiding mechanism, including a slide cylinder 1, which is mounted on a device base plate 27. A support base plate 2 is mounted on the output end of the slide cylinder 1. A slide cylinder 3 and a support block 4 are mounted on the support base plate 2. A support plate 5 is mounted on the top of the support block 4. A support base plate 6 is mounted on the output end of the slide cylinder 3. A guide block 7 is mounted on the front end of the support base plate 6. A folding block 8 is mounted on the front end of the guide block 7. A wiring harness guide block 9 is mounted on the front end of the support plate 5. The wiring harness guide block 9 passes through the guide block 7, and its front end is located at the front end of the folding block 8. A vertical plate 10 is mounted on the front end of the device base plate 27. A motor bracket 11 is installed on one side of the upright plate 10. A reducer 12 is installed on the motor bracket 11. A motor 13 is installed at the rear end of the reducer 12. A synchronous pulley 14 is installed at the output end of the reducer 12. The synchronous pulley 14 and the synchronous pulley 15 are connected by a synchronous belt 16. The front end of the synchronous pulley 15 is connected to the rotating wheel 16. The rotating wheel 16 is located in the groove 101 of the upright plate 10. The front end of the upright plate 10 is provided with a wire harness groove 102 that communicates with the groove 101. A pressure plate 17 is installed on the outside of the rotating wheel 16. The front ends of the wire harness guide block 9 and the folding block 8 both pass through the rotating wheel 16. Several circumferentially distributed wire harness pressure blocks 18 are installed at the front end of the rotating wheel 16.

[0031] The braided wire harness to be folded is first positioned at the wire harness guide block 9. Then, the motor 13 operates, driving the synchronous pulley 15 via the synchronous belt 16, which in turn drives the connected rotating wheel 16 to rotate. The rotating wheel moves the wire harness pressure block 18 to compress the wire harness. Then, the slide cylinder 3 operates, ultimately driving the folding block 8 to move, thus folding the braided layer of the wire harness. These actions eliminate manual operation and improve folding efficiency.

[0032] In one embodiment of this utility model, a cover plate 19 is installed on the outer side of the timing pulley 15. The cover plate 19 serves to seal and prevent dust.

[0033] In one embodiment of this utility model, the front end of the rotating wheel 16 is provided with a timing pulley second mounting groove 161. One end of the timing pulley second is engaged in the timing pulley second mounting groove 161 and then connected with fasteners. The middle of the rotating wheel 16 is provided with a folding block through hole 162 and several circumferentially distributed arc-shaped holes 163. The folding block through hole 162 is located at the center position. A mounting post 20 is installed on the wire harness pressing block 18, and the other end of the mounting post 20 is located at the arc-shaped hole 163. When the rotating wheel 16 rotates, the mounting post 20 rotates with the arc-shaped hole 163, driving the wire harness pressing block 18 to move. In this way, the spacing between the multiple wire harness pressing blocks 18 will also change accordingly. When the spacing is at its minimum, the wire harness is pressed tightly, so that the wire harness will not move when the braided layer is folded.

[0034] In one embodiment of this utility model, the wire harness pressing block 18 is triangular, with a pointed tip 181 on one side and a groove 182 corresponding to the pointed tip on the other side. The pointed tip 181 of one wire harness pressing block 18 connects to the groove 182 of another wire harness pressing block 18, and the groove 182 of the third wire harness pressing block 18 connects to the pointed tip 181 of the fourth wire harness pressing block 18. The pointed tips of all the wire harness pressing blocks 18 face the center of the rotating wheel 16. When the wire harness pressing block 18 presses the wire harness, the pointed tip 181 of the wire harness pressing block 18 contacts the wire harness. Moreover, when the wire harness pressing block 18 moves, the pointed tip 181 can only slide in the groove 182, ensuring the direction of movement of the wire harness pressing block 18 and preventing it from shaking.

[0035] In one embodiment of this utility model, a plurality of limiting posts 21 are provided on one side of the rotating wheel 16 where the wire harness clamping block is mounted, and the number of limiting posts 21 is twice that of the wire harness clamping block 18. The limiting posts 21 limit the farthest position of the wire harness clamping block 18 when it is separated.

[0036] In one embodiment of this utility model, a sealing box 22 is installed at the front end of the upright plate 10. A wire harness passage hole 221 is provided at the middle of the front end of the sealing box 22. A sealing block 23 is installed at the top of the sealing box 22, and a sealing block 24 is installed at the bottom. A connecting hole 231 is provided on the sealing block 23, which connects to the pipeline of the static eliminator nozzle 25. An outlet hole is provided at the bottom of the sealing block 24. The sealing box 22 serves a protective function, preventing dust from entering the interior during operation. The static eliminator nozzle 25 eliminates static electricity because broken shielding wires are adsorbed onto the wires, requiring the removal of static electricity adsorption on the shielding wires by blowing plasma air. The static eliminator nozzle can be a static eliminator nozzle from Keyence Corporation.

[0037] In one embodiment of this utility model, the wire harness guide block 9 includes a guide block mounting block 91 and a guide block body 92. The rear end of the guide block body 92 is mounted on the guide block mounting block 91, and the guide block mounting block 91 is mounted on the support plate 5. The front end of the guide block body 92 is provided with a wire harness slot 9201. The guide block body 92 has a stepped structure and includes a first guide block body 921 and a second guide block body 922. The diameter of the first guide block body 921 is larger than the diameter of the second guide block body 922. The front end of the first guide block body 921 is provided with a plurality of air guide grooves 9211. The air guide grooves 9211 can guide air through other auxiliary braiding.

[0038] In one embodiment of this utility model, the folding block 8 includes a folding tube 81 and a fixing block 82. The fixing block 82 is located on the outer side of the rear end of the folding tube 81 and is connected to the guide block 7. The upper end of the fixing block 82 is provided with an air inlet groove 821. The middle of the folding tube 81 is provided with a guide block body through hole 811. The air inlet groove 821 communicates with the guide block body through hole 811. The air inlet groove 821 is connected to the solenoid valve 26. When the solenoid valve 26 is vented, the gas enters from the air inlet groove 821 and then enters the air guide groove 9211, and finally blows towards the wire harness. The solenoid valve 26 and the static elimination nozzle 25 are mounted on the device base plate 27.

[0039] In one embodiment of this utility model, the device base plate 27 is mounted on the linear module 28. The linear module 28 can drive the entire assembly to move horizontally.

[0040] In one embodiment of this utility model, a finger cylinder 29 is also included. The finger cylinder 29 is equipped with two clamping plates 30, each of which is provided with a corresponding semi-circular wire harness hole 301. The finger cylinder 29 can drive the two clamping plates 30 to clamp the wire harness.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
