in the step d, the moving assembly of the PCB numerical control machine tool drives the pin punching assembly to move above the appointed pin hole, the up-down driving device pushes the sliding connecting plate to move downwards, the lower part of the pin is sent into the pin hole, and the step e is performed;
the step e is as follows: f, pressing down the driving device to drive the guide rod to strike the top of the pin, stopping striking after the pin enters the pin hole to be qualified in length and does not fall off, and entering the step f;
and f, repeating the steps b-e until all specified pin holes of the PCB are driven into pins.
10. The automatic pin punching method of the PCB numerical control machine tool according to claim 9, further comprising a step g after the step f, wherein the step g is as follows: detecting the striking effect of pins in all specified pin holes of the PCB through a detection assembly, if the striking effect is qualified, finishing the striking, if the striking effect is unqualified, acquiring unqualified pin information, moving the striking assembly to the position above the pin, and repeating the step e until the detection is qualified, and finishing the striking;
the detection component is at least one of a CCD camera component, a metal sensor component, an infrared sensor component or an optical fiber sensor component.
