[0026] like Figure 1 to Figure 5 As shown, this embodiment proposes an automatic shoe sole sewing device, the shoe sole sewing device includes a machine 1 and a shoe sole clamping mold 2, a conveying robot 3, and a sewing device arranged on the machine 1, the shoe sole clamping mold 2 is used to fix the shoe sole, wherein the sewing device includes a clamping component 4, a wire arrangement component 5, and a needle threading component 6, wherein two of the wire arrangement components 5 are respectively arranged on both sides of the needle threading component 6, and two of the needle threading components 6 are respectively arranged on both sides of the needle threading component 6, wherein the wire arrangement component 5 is arranged between the needle threading component 6 and the clamp The holding assembly 4 includes a fixed splint 7 and a movable splint 8, and the fixed splint 7 and the movable splint 8 are both provided with a needle threading hole 9. The conveying robot 3 is used to place the sole clamping mold 2 between the fixed splint 7 and the movable splint 8. The needle threading assembly 6 can lock and clamp the sewing needle. The needle threading assemblies 6 on both sides alternately pass the sewing needle through the needle threading hole 9 to sew the sole. After the sewing needle passes through the sole, the wire arrangement assembly 5 pulls all the threads of the sewing needle to the same side as the sewing needle.

[0027] In this embodiment, an automatic shoe sole sewing device is disclosed. During its working process, on the machine table 1, the sole is fixed on the sole clamping mold 2, and the transport robot 3 clamps the sole clamping mold 2 and places it on the sewing device. Specifically, it is placed on the clamping component 4, and the sole clamping mold 2 is clamped by the movable clamp 8 and the fixed clamp 7. At this time, the needle threading component 6 located on one side of the clamping component 4 clamps the sewing needle and aligns it with the needle threading hole 9 to pass through the sole. On both sides of the threading hole, a threading hole 9 can be set. The thread break detection sensor is used to monitor the continuity of the thread. At this time, the needle threading assembly 6 on the other side will catch the sewing needle that has passed through and clamp it to lock it. At this time, the needle threading assembly 6 on the starting side will release the sewing needle, and the needle threading assembly 6 on the other side will pull the needle out of the sole. Then, the wire arrangement assembly 5 on the other side will pull all the threads pulled by the sewing needle to the same side as the sewing needle, and then adjust the position of the sole clamping mold 2 on the clamp assembly to distance it from the next needle threading position, and repeat this process to sew the sole.
