Automatic pin feeding device for circuit board production

The utility model relates to the technical field of circuit board production, in particular to an automatic pin mounting device for circuit board production, which comprises a sliding rail, a pin mounting mechanism and a pin mounting mechanism. A through groove is formed in the outer wall of one side of the sliding rail, symmetrical sliding grooves are formed in the inner wall of the bottom end of the sliding rail, and a first limiting groove is formed in the inner wall of one side, far away from the through groove, of the sliding rail; the fixing device has the beneficial effects that when the movable block needs to be fixed, the rotary knob is rotated to enable the threaded rod to rotate to enter the adjusting groove, meanwhile, the positioning rod at one end moves towards one end of the fixing plate, and one end of the positioning rod abuts against the positioning hole; during extrusion, the side wall of the positioning rod abuts against the side wall of the positioning hole, so that the fixing plate sligh
