The invention relates to a workpiece feeding device of an electronic component. The workpiece feeding device of the electronic component comprises a transverse moving part and a longitudinal moving part, wherein the longitudinal moving part is arranged on the transverse moving part, the transverse moving part and the longitudinal moving part are driven by a second disc-shaped cam and a first disc-shaped cam respectively, the second disc-shaped cam and the first disc-shaped cam are arranged in a main shaft device, and the main shaft device is connected with a power device; the main movement track of a rectangular wave inserting strip is a rectangle after the movement of the transverse moving part and the longitudinal moving part is combined, a plurality of stirring holes which are formed byrectangular waves are formed in the bottom of the rectangular wave inserting strip, the longitudinal moving part moves downwards to drive the rectangular wave inserting strip to enter a high-pressuredust removing device, then the transverse moving part drives the rectangular wave inserting strip to move leftwards, and the poking opening pushes a workpiece, and then the longitudinal moving part drives the rectangular wave inserting strip to move out of the high-pressure dust removing device, the transverse moving part is used for leftwards moving and resetting the rectangular wave inserting strip, and the workpiece is repeatedly operated to intermittently push the workpiece to move forwards.
