[0070] The wire clamp 78 includes a fixed mounting block 781 fixed to the second rotating support plate 76, a fixed seat 782 fixed to the fixed mounting block 781, a lifting driving rod 783 movably arranged on the fixed seat 782, a pair of lever arms 784 whose bottom ends are hinged on the fixed seat 782 and are arranged opposite to each other, a connecting rod 785 with one end hinged to the middle of the lever arm 784 and the other end hinged to the top of the lifting driving rod 783, a clamp 786 fixed to the top of the lever arm 784, and an elastic member 787 arranged on the fixed seat 782 to press the lever arm 784 toward the clamping state. In the initial state, under the action of the elastic member 787, the two clamps 786 are in a clamping state; when the lifting driving rod 783 moves upward, the two connecting rods 785 at the top of the lifting driving rod 783 tend to be horizontal and in a straight line, thereby pushing the lever arm 784 outward, thereby realizing the opening action of the clamp 786.

[0071] The coiling unit 7 further includes a jaw opening mechanism 79 for opening the wire clamping jaws 78. The jaw opening mechanism 79 includes a twelfth air cylinder 791 and a lifting block 792 driven by the twelfth air cylinder 791 to lift the lifting driving rod 783 upward to open the jaws. The jaw opening mechanism 79 is fixed on the first rotating support plate 74.

[0072] When rolling, the eleventh cylinder 75 drives the first rotating support plate 74 to rise, the winding support shaft 77 passes through the second rotating support plate 76 to form a winding limit core disk, and the jaw opening mechanism 79 rises to the set position along with the first rotating support plate 74, and then the twelfth cylinder 791 is started, the lifting block 792 extends upward, driving the lifting driving rod 783 upward, thereby opening the clamping jaw 786, and after the end of the single bundle of multi-strand wires wrapped with the tape is pulled to the position of the wire clamping jaw 78, the lifting block 792 descends, and the clamping jaw 786 is in the elastic member. 787 clamps the end of the wire; then the ninth motor 72 starts, driving the second rotating support plate 76 to rotate synchronously with the winding support shaft 77, winding the wire around the outer periphery of the winding support shaft 77 to form a reel, completing the winding operation. After winding, the lifting block 792 rises, driving the clamping claw 786 to open, and the second rotating support plate 76 continues to rotate at a set angle, so that the wire is disengaged from the clamping claw 786, and then the rolled wire is taken away. When taking it away, the winding support shaft 77 can cooperate with the downward movement to facilitate the removal of the wire.

[0073] The action flow of the multi-strand fine wire automatic unwinding and twisting and winding device 100 of this embodiment is as follows: a plurality of fine wire reels to be twisted are fixed on the unwinding support shaft 122 of the unwinding drive assembly 12 for automatic unwinding, and the wires are output to the wire feeding unit 2 through the tension control assembly 13 and the wire dividing assembly 14 in turn; in the wire feeding unit 2, the wires are subjected to stress elimination and shaping by the shaping assembly 22, and then enter the wire feeding roller assembly 24 through the single-wire conveying assembly 23, and the wires are conveyed forward one by one through the wire feeding roller assembly 24; and then enter the third wire tube 36 of the cutting unit 3, during which the laser marking unit 9 performs laser marking on the surface of each wire according to the set interval length; when it is necessary to cut it, the second cylinder 24 The driven wire pressing wheel 243 is driven to press the wires tightly to keep them stationary, and then the lower cutter 32 and the upper cutter 33 cooperate to cut the wires; if cutting is not required, the wires are output from the third wire tube 36 to the fourth wire tube 42 of the bundle-binding mold 4, and are preliminarily bundled through the bundle-binding enclosure 45, and then further bundled and extruded through the first bundle-binding clamp 51 and the second bundle-binding clamp 53 in the bundle-binding and extruding unit 5; after the bundle-binding is completed, the ends of the wires are clamped by the clamping and drawing unit 8, and then the outer peripheral surfaces of the bundled single-bundle multi-strand wires are wrapped with tape through the tape wrapping unit 6, until the ends of the wires can be pulled to the wire clamp 78 of the coiling unit 7 and clamped, and then the coiling unit 7 is started, and the wires are automatically coiled.

[0074] The automatic winding and coiling equipment 100 for multiple strands of fine wires in this embodiment can realize the bundling and coiling operation of 30 strands of wires, realize automatic winding, greatly improve the efficiency and automation of winding multiple strands of fine wires, and improve the quality of winding.

[0075] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
