WORKPIECE CONVEYANCE DEVICE

This workpiece conveyance device (1) comprises: a plurality of holding heads (2) having a holding section for holding a workpiece (W) and a vacuum pump (22) for generating holding force; and a conveyance track (4) for conveying the plurality of holding heads (2). The vacuum pump (22) has a pump section (34) that communicates with the holding section and suctions or discharges ambient air, and a shaft section (36) for operating the pump section (34) by means of rotation. The shaft section (36) includes a first magnet (48) in which the N pole and the S pole are magnetized in an alternating manner around the axis. The conveyance track includes a second magnet (18) extending in the conveyance direction (D1) of the holding heads and arranged so that magnetic force from the N pole and magnetic from the S pole are generated in an alternating manner in the conveyance direction (D1) and magnetic force is generated in the area between said second magnet (18) and the first magnets (48) of the holding heads. The shaft sections (36) rotate and the pump sections (34) are made to generate holding force as a result of the magnetic poles shifting in an alternating manner in the part of the second magnet (18) in which magnetic force is generated with respect to the first magnets (48) .
