The utility model discloses a LED filament welding equipment's stem stem welding foot correction mechanism, including the X that is used for revising the position of welding foot on the extending direction of perpendicular to stem stem to correction mechanism with be used for revising the extending direction that the welding foot is being on a parallel with the stem stem on the Y of position to correction mechanism, wherein, X includes to correction mechanism that X presss from both sides first driving piece tight and that loosen with drive X to spacing subassembly to spacing subassembly, theextending direction of the pinch plane equal perpendicular to stem stem of X on to spacing subassembly, Y includes to correction mechanism that Y presss from both sides second driving piece tight andthat loosen with drive Y to spacing subassembly to spacing subassembly, Y presss from both sides tight pinch plane on the welding foot at stem stem both ends on to spacing subassembly and is located the coplanar, and is on a parallel with the extending direction of stem stem. This stem stem welding foot correction mechanism can revise the welding foot of stem stem before the welding to ensure thatthe welding foot at stem stem both ends can be accurately docks with the welding foot of filament.
