Abstract:
1. A workpiece conveying apparatus comprising: a conveying stage having a conveying surface for conveying a workpiece; a conveying table having a first surface arranged to face the conveying surface of the conveying stage and a second surface opposite the first surface, the conveying table having a through hole extending from the first surface to the second surface; first means for enabling the conveying table to slide and move relative to the conveying surface while the first surface of the conveying table faces the conveying surface of the conveying stage, said first means being connected to at least one of the conveying table and the conveying stage, wherein the workpiece conveying apparatus conveys the workpiece by moving the conveying table relative to the conveying surface while the workpiece is disposed in the through hole in the conveying table, wherein the conveying surface of the conveying stage has an exhaust hole through which compressed gas is jetted to dismount the workpiece disposed in the through hole, the exhaust hole being located at a workpiece dismounting position where the exhaust hole is alignable with the through hole, wherein the exhaust hole has an opening in the shape of a plurality of elongated nozzle sections whose longitudinal direction corresponds to a direction in which the workpiece is conveyed; and second means for receiving compressed gas from a compressed-gas supplying source, said second means comprising a hose connected to the exhaust hole, wherein said plurality of nozzle sections of the exhaust hole proximate to the conveying table have a predetermined total area that is larger than or equal to a predetermined end surface area of the workpiece facing the conveying surface of the conveying stage and said plurality of nozzle sections in each said exhaust hole are disposed so that said workpiece, having said end surface area, bridges between all of said plurality of nozzle sections in said exhaust hole, so that the compressed gas is jetted through all of the plurality of the nozzle sections to dismount the workpiece; and wherein elongated retaining sections are disposed between said elongated nozzle sections, and a longitudinal direction of the retaining sections defined between the nozzle sections extends in the direction in which the electronic component is conveyed.
