[0029] Please refer to Figures 2 - 3, in order to fix spools of different models, make the spool rotate at a uniform speed during wiring, effectively avoid the problem of wire harness detachment caused by spool slack, and prevent the spool from reversing. The fixing structure 2 includes a first support plate 21. Above the left side of the first support plate 21, a first connecting plate 22 is fixedly connected. On the right side of the top of the first connecting plate 22, a rectangular mounting hole 23 that penetrates up and down is opened. On the left and right sides of the inner wall of the rectangular mounting hole 23, slide bars 24 are fixedly connected. On the right outer wall of the slide bar 24, a first spring 25 is sleeved. On the left outer wall of the slide bar 24, a sliding sleeve 26 is movably connected. On the top of the sliding sleeve 26, a pushing block 27 is fixedly connected. On the left side of the first connecting plate 22, a second support plate 28 is fixedly connected. On the bottom of the sliding sleeve 26, a first mounting plate 20 is fixedly connected. Below the left side of the first mounting plate 20, a circular moving hole that penetrates to the right is opened. Inside the inner wall of the circular moving hole, a first connecting shaft 201 is movably connected. On the left end of the first connecting shaft 201, a first tapered block 202 is fixedly connected. On the left side of the first connecting plate 22, a second support plate 28 is fixedly connected. At the position corresponding to the circular moving hole on the second support plate 28, a circular mounting hole that penetrates left and right is opened. Inside the circular mounting hole, a reverse stop assembly 29 is arranged. The reverse stop assembly 29 includes a first fixing plate 291. On the left side of the first fixing plate 291, a second mounting plate 292 is fixedly connected. On the rear side of the bottom of the second mounting plate 292, an arc-shaped clamping block 293 is hinged. On the front side of the bottom of the second mounting plate 292, a second spring 294 is fixedly connected. The bottom of the second spring 294 is fixedly connected to the front side of the arc-shaped clamping block 293. On the surface of the arc-shaped clamping block 293, a first gear 297 is meshed. On the right end of the first gear 297, a second connecting shaft 295 is fixedly connected. The outer wall of the second connecting shaft 295 is movably connected to the inner wall of the circular mounting hole. On the right end of the second connecting shaft 295, a second tapered block 296 is fixedly connected. First, push the pushing block 27 to make the pushing block 27 drive the sliding sleeve 26 to slide on the outer wall of the slide bar 24 and compress the first spring 25. Then, the circular hole in the center of spools of different models can be aligned with the second tapered block 296 to make the second tapered block 296 fit the circular hole. Then, release the pushing block 27. Under the action of the first spring 25, push the sliding sleeve 26 to make the sliding sleeve 26 drive the first mounting plate 20, the first connecting shaft 201, and the first tapered block 202 to move. Furthermore, the outer wall of the first tapered block 202 fits the circular hole on the other side of the spool, achieving the effect of clamping and fixing spools of different models. When the driving motor 388 is started to lay the wire harness, the wire harness drives the spool to rotate. The spool drives the first tapered block 202 to make the first connecting shaft 201 rotate in the circular moving hole of the first mounting plate 20. At the same time, on the other side, it drives the second tapered block 296 and makes the second connecting shaft 295 rotate in the circular mounting hole of the second support plate 28. By the rotation of the second connecting shaft 295, the first gear 297 is driven to rotate. The teeth of the first gear 297 slide on the arc surface of the arc-shaped clamping block 293. When the arc surface of the arc-shaped clamping block 293 contacts the teeth, the arc-shaped clamping block 293 compresses the second spring 294.When the arc surface of the arc-shaped clamping block 293 slides over the tooth of the first gear 297, the arc-shaped clamping block 293 will be pushed under the action of the second spring 294, so that the arc-shaped clamping block 293 stays between two teeth, achieving the effect of preventing the first gear 297 from reversing.

[0030] Working principle:

[0031] First, push the push block 27, so that the push block 27 drives the sliding sleeve 26 to slide on the outer wall of the sliding rod 24 and compresses the first spring 25. Then, the circular hole in the center of the wire reels of different models can be aligned with the second tapered block 296, so that the second tapered block 296 fits the circular hole. Then release the push block 27. Under the action of the first spring 25, the sliding sleeve 26 is pushed, so that the sliding sleeve 26 drives the first mounting plate 20, the first connecting shaft 201, and the first tapered block 202 to move. Furthermore, the outer wall of the first tapered block 202 fits the circular hole on the other side of the wire reel, achieving the effect of clamping and fixing wire reels of different models. When the drive motor 388 starts to lay the wire harness, the wire harness drives the wire reel to rotate. The wire reel drives the first tapered block 202 to make the first connecting shaft 201 rotate in the circular moving hole of the first mounting plate 20. At the same time, on the other side, it drives the second tapered block 296 and makes the second connecting shaft 295 rotate in the circular mounting hole of the second support plate 28. The rotation of the second connecting shaft 295 drives the first gear 297 to rotate. The teeth of the first gear 297 slide on the arc surface of the arc-shaped clamping block 293. When the arc surface of the arc-shaped clamping block 293 contacts the teeth, the arc-shaped clamping block 293 compresses the second spring 294. When the arc surface of the arc-shaped clamping block 293 slides over the teeth of the first gear 297, the arc-shaped clamping block 293 will be pushed under the action of the second spring 294, so that the arc-shaped clamping block 293 stays between two teeth, achieving the effect of preventing the first gear 297 from reversing;

[0032] The rotation of the second rotating shaft 387 is started by driving the driving motor 388, and the rotation of the second rotating shaft 387 drives the rotation of the third gear 386. The third gear 386 is meshed and connected with the upper second gear 385, and the two second gears 385 are meshed and connected. Then, the rotation of the third gear 386 causes the two second gears 385 to rotate in opposite directions. The wire harness contacts the outer walls of the two rubber pads 384 through the first material guiding hole 36. The rotation of the two second gears 385 drives the rotation of the two fixed rollers 383, and then the two fixed rollers 383 drive the rubber pads 384 on the outer walls to rotate to squeeze the wire harness. After passing through the outer walls of the two rubber pads 384, the wire harness passes through the second material guiding hole 30 and fits with the outer wall of the wire routing wheel 396. By pushing the mounting table 1 to drive the rotation of the four rollers 4, the wire routing wheel 396 lays the wire harness. The rotation of the first rotating shaft 32 is started by the stepping motor 31, which drives the rotation of the threaded rod 33. Then, the slider 34 moves on the outer wall of the threaded rod 33. The movement of the slider 34 drives the movement of the second fixing plate 35, the first material guiding hole 36, the second connecting plate 37, the wire guiding assembly 38, the buffer assembly 39, and the second material guiding hole 30, so as to change the laying path.
