Detailed Description

The present invention will be described in detail with reference to the following embodiments and accompanying drawings.

As shown in fig. 1 to 3, the paying-off mechanism for micro wires of the present embodiment includes a base 1, a supporting disc 2, a central rotating shaft 3 and a plurality of positioning pillars 4, wherein the central rotating shaft 3 rotatably stands on the base 1, the supporting disc 2 is provided with mounting holes 21 arranged along a radial direction, and lower ends of the positioning pillars 4 are fixed in the mounting holes 21. The base 1 is also provided with a driving mechanism for driving the central rotating shaft 3 to rotate, the driving mechanism comprises a motor and a reduction gearbox, and the motor drives the central rotating shaft 3 to rotate through the reduction gearbox. Supporting disk 2 is fixed in central pivot 3 horizontally, and many reference columns 4 are fixed in supporting disk 2 and distribute around central pivot 3 circumference. The base 1 is provided with a plurality of wire coils 5 arranged around the circumference of the support disc 2, the wire coils 5 comprise a bracket 51 and a rolling disc 52, the bracket 51 is fixed on the base 1, the rolling disc 52 is rotatably arranged on the bracket 51, and the outer side of the rolling disc 52 is provided with a V-shaped wire guiding groove. Wherein the rolling discs 52 of one part of the wire coil 5 are transversely arranged, the rolling discs 52 of the other part of the guide discs are longitudinally arranged, and the rolling discs 52 of the plurality of guide discs are staggered in the longitudinal direction.

The switch assembly 6 is further arranged beside the support disc 2, the switch assembly 6 comprises a switch body 61, a rotary block 62 rotatably mounted on the switch body 61, a lead wire rod 63 fixed at one end of the rotary block 62 and a balance weight 64 fixed at the other end of the rotary block 62, and the balance weight 64 and the lead wire rod 63 are in mutual lever balance by taking the rotation axis of the rotary block 62 as a fulcrum, namely, the weight of the balance weight 64 and the horizontal distance from the center of the balance weight 64 to the fulcrum are equal to the weight of the lead wire rod 63 and the horizontal distance from the center of the lead wire rod 63 to the fulcrum. The rotation of the rotary block 62 can trigger the motor of the driving mechanism to start, and then the central rotating shaft 3 and the supporting disk 2 are driven to rotate.
