The erection rod assembly 71 includes two guide rods 711 spaced apart from each other on the support frame 40, an erection rod 712 installed on the guide rods 711, and a plurality of heads 713 installed on the erection rod 712. The guide rod 711 is fixedly disposed on the bracket 40 to ensure stability in the reciprocating motion of the bridge rod 712. The mounting rod 712 is used to position the plurality of heads 713 such that the plurality of heads 713 move in unison. The structure and shape of the plug 713 are adapted to the structure and shape of the propping assembly 72, so as to ensure that the plug 713 can prop against the propping assembly 72 for movement. The propping assembly 72 comprises a base 721 arranged on the clamping jaw assembly 53, a through hole 722 arranged on the base 721, a push rod 723 arranged in the through hole 722 of the base 721 in a penetrating way, a thimble 724 arranged on the push rod 722, a through groove 725 arranged on the push rod 723, a straight hole 726 arranged on the base 721, a fixing rod 727 arranged in the through groove 725 in a penetrating way and fixed on the straight hole 726, and an elastic member 728 with one end fixed on the fixing rod 727 and the other end fixed on the push rod 723.

The base 721 is fixedly disposed on the jaw assembly 53, and specifically, the base 721 is fixedly disposed on the pneumatic pump 521 on the jaw assembly 53 so as to be rotatable with the pneumatic pump 521. The through hole 722 is disposed on the base 721 to pass through the rod 722, so that the cross-sectional shape of the through hole 722 can be the same as that of the rod 722. The top rod 723 abuts against the top 713, so that the top 713 abuts against the top rod 723 to drive the top rod 723 to move forward. In order to realize that the ejector 723 can automatically recover after being ejected, the abutting assembly 72 is provided with the through slot 725, the fixed rod 726 and the elastic member 727. Specifically, the through groove 725 is formed along the moving direction of the top rod 723. The fixing rod 726 passes through and is fixed to the straight hole 727 of the base 721. The axial direction of the straight hole 727 is perpendicular to the moving direction of the push rod 723. The elastic member 728 is received in the through groove 725, and in particular, one end of the elastic member 728 is fixed to the fixing rod 726 and the other end is fixed to one end of the through groove 725. Since the fixing rod 726 is fixed to the base 721, when the rod 722 is pressed against, it is limited by the fixing rod 726 and the through hole 722 of the base 721. Specifically, when the top 713 abuts against the top rod 723, the top rod 723 moves forward, and the elastic member 728 is compressed. When the top 713 cancels the propping against the top rod 723, the elastic member 728 drives the top rod 723 to return to the original position, so that the top rod 723 returns to the original position, and the reciprocating motion of the top rod 723 is realized. The elastic member 728 may be an extension spring. The thimble 724 is used for propping against the tail wire of the coil wound on the flexible carrier so as to facilitate winding the coil. The structure and shape of the thimble 724 may be set according to actual requirements, and in this embodiment, the thimble 724 is in a "Z" shape, so that an end of the thimble 724 may extend to a vicinity of the chuck 532. Specifically, the thimble 724 is located on a symmetry plane of the two chucks 532. Since the top rod 723 and the top head 713 only have an abutting relationship and are not fixed to each other, when the abutting assembly 72 rotates with the clamping jaw mechanism 51, the top head 713 does not interfere with the rotation of the top rod 723.

The abutting driving mechanism 80 includes two abutting air pumps disposed on the bracket 40 at intervals. The output rod of the propping air pump props against the erection rod 712, so that when the propping air pump works, the propping air pump can prop against the erection rod 712 to move towards the top rod 723 and further prop against the thimble 724 to prop against the tail wire of the coil, so as to wind the coil.

Compared with the prior art, the utility model provides a multiaxis flexible carrier clamping jaw mechanism organically is with clamping jaw group 50, clamping jaw mechanism 51, clamping jaw actuating mechanism 60, supports top mechanism 70 to and support top actuating mechanism 80 and assemble together, thereby make clamping jaw mechanism 51 with support top mechanism 70 and can accomplish its work respectively and mutually noninterfere. Particularly, the abutting assembly 70 is structurally designed so that the base 721, the ejector rod 723, the ejector pin 724 and other assemblies can rotate along with the clamping jaw mechanism 51, and meanwhile, when the ejector rod 723 is abutted by the abutting driving mechanism 80, the clamping jaw mechanism 51 is not affected, thereby facilitating the realization of automation of the multi-axis winding machine.
