A cylinder gasket is installed between the two tapered guide nozzle opening and closing swing arms 7. When the tapered guide nozzle opening and closing cylinder 2 exits, the two tapered The guide nozzle opening and closing swing arm 7 is reset under the elastic force of the cylinder gasket. A guide rail 5 is installed on the left side of the main bracket 1. A slider 15 is slidably provided on the guide rail 5. The connecting frame 14 is installed on the slider 15. The middle clamp reciprocating cylinder 13 is installed on the left side of the main bracket 1, and its output end is connected to the bottom wall of the slider 15; the middle clamp base 11 is installed on the left side of the connecting frame 14, and the middle clamp opening and closing cylinder 12 is installed at the bottom of the middle clamp base 11. The output end of the middle clamp opening and closing cylinder 12 passes through the bottom plate of the middle clamp base 11 and is connected to the middle clamp opening and closing push rod 10. The middle clamp opening and closing push rod 1 0's wing plate is movably inserted into the strip groove on the side wall of the middle clamp base 11; the top of the middle clamp base 11 is symmetrically screwed with the middle clamp jaws 9, and the opposite surfaces of the middle clamp jaws 9 are provided with a serrated structure, and the conical guide nozzle 8 and the middle clamp jaws 9 are arranged correspondingly up and down; a cylinder gasket is installed between the two middle clamp jaws 9, and when the middle clamp opening and closing push rod 10 retreats, the two middle clamp jaws 9 are reset under the action of air pressure, and the wing plate of the middle clamp opening and closing push rod 10 is movably clamped between the bottoms of the two middle clamp jaws 9; the bottom of the connecting frame 14 is installed with an anti-backlash cylinder 16.

[0020] When using the present invention, under the action of the high-precision positioning of the image positioning system and the CNC XYZ platform, a complete conical wire hole formed by the closing of the two conical guide nozzles 8 is aligned with the target aperture, and the lead is smoothly introduced into the target aperture within the allowable error before completing other related operations. Specifically, after the lead to be guided passes through the two middle clamping jaws 9, it is sent into the two conical guide nozzles 8, and the middle clamp opening and closing cylinder 12 is extended to push the middle clamp opening and closing push rod 10 to rise, thereby pushing the top of the two middle clamping jaws 9 to rotate and close together to catch the lead.

Finally, it accurately passes through the tapered wire hole (PCB perforation or to pass through the working aperture greater than the wire diameter + 0.3mm requirement) and the target aperture (the target hole and the cone top wire hole are concentric). Then the middle clamp opening and closing cylinder 12 and the tapered guide nozzle opening and closing cylinder 2 withdraw, and the two middle clamp jaws 9 and the two tapered guide nozzle opening and closing swing arms 7 open and reset under the action of air pressure. The lead wire withdraws and the middle clamp reciprocating cylinder 13 retracts, thereby lowering and resetting the middle clamp jaws 9 to complete the threading operation.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides a guiding mechanism for perforating welding wires, which is driven by a conical guide nozzle opening and closing cylinder to realize the opening and closing of two conical guide nozzle opening and closing swing arms, thereby realizing the opening and closing of the two conical guide nozzles, and the wire is led along the inner wall of the conical guide nozzle, thereby successfully leading the wire out of the required threading position; and in conjunction with the middle clamping claw, it can clamp the lead wire during the threading process, and utilize the middle clamping reciprocating cylinder to send the clamped lead wire into the conical guide nozzle, thereby realizing the limitation of the lead wire during the threading process, mechanized operation, improved threading accuracy, and improved threading efficiency.
