Positioning device for welding PCB direct-inserting type component array

The utility model discloses a positioning device for welding a PCB direct-inserting type component array. The positioning device comprises a base, guiding columns and a pressing plate, wherein the base is provided with a locking piece and grooves, each guiding column is provided with a sliding end and a fixed end, the sliding ends of the four guiding columns are vertically inserted in the pressing plate in a sliding mode, tightening pieces are arranged on the side end faces of the pressing plate, and the pressing plate is arranged above the grooves of the base; a PCB is fixed to the base through the locking piece, the fixed ends of the guiding columns are fixed to the PCB, and direct-inserting type components on the PCB are arranged between the pressing plate and the grooves. The positioning device can effectively overcome the defect that the direct-inserting type components cannot be tightly attached to the PCB, the direct-inserting type components of the array can be conveniently and quickly pressed at a time, and meanwhile, the problem that traditional manual single inserting components are twisted, bent and inclined and interfere with one another is effectively avoided.
