9. The plastic wire welding device according to claim 1, wherein a shaft seat is mounted on the base, a fifth motor is mounted on the shaft seat, a second threaded rod is mounted at an output end of the fifth motor, the second threaded rod is in threaded connection with a sliding plate, a sliding rail groove is formed in the base, and a sleeve block matched with the sliding rail groove is mounted at the bottom of the sliding plate.

10. The method for operating a plastic wire bonding apparatus according to any one of claims 1-9, wherein the method comprises the following steps:

the method comprises the following steps: the wire is conveyed through the wire conveying assembly of the wire feeding mechanism, the roller seat is elastically connected with the roller plate, a first limiting plate connected with a first adjusting rod of the roller seat moves in the first built-in groove to compress the first spring, so that the distance between the roller seat and the conveying roller on the roller plate is adjusted, and the wires with different wire diameters are conveyed;

step two: the wire passes through a wire barrel of the peeling assembly, the second driving tooth is driven to rotate by the work of a fourth motor at the moment, the wire is meshed with the second external tooth to realize the rotation of the adjusting disc, the guide roller moves along the arc-shaped groove and the limiting groove at the moment, a moving seat connected with the connecting block is driven to move along the guide rail until the pressing wheel and the cutting knife are contacted with the outer wall of the wire, the first driving tooth is driven to rotate by the work of a third motor, the wire barrel rotates by being meshed with the first external tooth, the pressing wheel rolls along the outer wall of the wire at the moment, the cutting knife cuts along the outer wall of the wire, the movement of the pressing wheel and the cutting knife is realized by the work of the fourth motor, the wheel seat drives a second limiting plate to move upwards in a second built-in groove through a second adjusting rod, the second spring is stretched, the pressing wheel rolls along the outer wall of the wire all the time under the action of the second spring, and the cutting knife cuts into the surface of the wire to complete the circular cutting of one end of the wire;

step three: after the cutting is completed, the peeling cylinder works to drive the cutter arm and the cutting knife to move at the moment, the surface of the wire is peeled off, the wire automatically falls into the discharge hopper, then the first motor works to drive the first threaded rod to rotate, and then the sliding seat of the threaded connection is driven to move, the wire feeding mechanism moves integrally, then the wire is conveyed to a wire groove corresponding to the welding wire jig by the matching wire conveying assembly, the wire is fixed through the glass cover plate, the wire is cut through the matching of the downward moving slitting knife and the cutting seat, then the circular cutting of the other end of the wire is completed through the operation in the step two, the substrate is positioned on the sliding plate at the moment, the welding mechanism moves the welding head to align the peeling joint of the wire and the substrate, and then the welding head moves downward to weld the wire and the substrate.
