The invention discloses a PCB
welding jig. The PCB
welding jig comprises a supporting cover plate and a base, wherein the bottom of the supporting cover plate is fixedly connected with a telescopic rod; a sleeve is fixed on the base; the telescopic rod is embedded in the sleeve and is movably connected with the sleeve; the bottom of the supporting cover plate is connected with a clamping head through a connecting piece; a positioning block is fixed at one end of the surface of the base; an elastic supporting piece is fixed on the side end face of the positioning block; an
air pump is installed on the positioning block; an air
nozzle is installed on the positioning block on the bottom of the elastic supporting block, and communicates with the
air pump; a positioning piece is fixed at one end of the base, and a
threaded rod is arranged on the positioning piece in a penetrated manner; one end of the
threaded rod is connected with a positioning rod, and an
extrusion head is fixed at the end of the positioning rod. The PCB
welding jig is compact in structure and convenient to use, a PCB can be clamped well, the PCB is extremely stable in the
welding process through multi-dimensional positioning, and a PCB to be machined is convenient to place in the
welding process, so that the PCB welding jig is convenient for workers to use, and the
machining time is reduced.
