A method and a device for producing bipolar plates for fuel cells. A bipolar plate is formed by joining an anode plate to a cathode plate, wherein the anode plate and the cathode plate are formed by forming a substrate plate. In order to provide a cost-effective and automated method, it is proposed that a plate already provided with a reactive coating or catalyst coating, which is transported, automatically driven, via a transport device from the forming device to the joining device, is used as substrate plate.

A conveyor apparatus that includes a support, a crossbar and a plurality of tools attached to the crossbar. The crossbar is suitable for being moved to convey a workpiece and is supported only by the support. The crossbar includes first and second segments that are located on opposite sides of the support. First and second tools are respectively attached to the first and second segments. The conveyor apparatus includes at least one passive vibration compensation block attached to at least one element of the conveyor apparatus selected from the crossbar, the first tool, and the second tool, to reduce vibrations generated during the movement of the crossbar.

Provided is a workpiece conveying apparatus including: two SCARA robots each including: a raising and lowering frame supported on a stationary frame so as to be movable in an up-and-down direction, the stationary frame being mounted to extend along a width direction orthogonal to a workpiece conveying direction of a passage space for conveying a workpiece; a first arm supported on the raising and lowering frame through intermediation of a first joint; a second arm held through intermediation of a second joint; a first arm driving mechanism configured to drive the first arm to rotate; and a second arm driving mechanism configured to drive the second arm to rotate; raising and lowering mechanisms arranged to correspond to the two SCARA robots, respectively, and configured to enable the corresponding raising and lowering frames to mutually independently move in the up-and-down direction; a cross arm; and a cross bar unit.

A workpiece conveying apparatus includes: two SCARA robots each including a first arm supported on a raising and lowering frame through intermediation of a first joint, a second arm supported through intermediation of a second joint, a first arm driving mechanism configured to drive the first arm to rotate, and a second arm driving mechanism configured to drive the second arm to rotate; a raising and lowering mechanism for the two SCARA robots; a cross arm configured to couple distal ends of the second arms; a workpiece holding unit configured to releasably hold the workpiece; shifting devices provided to the cross arm and configured to shift a drive-side shifting member; and sliding devices provided to the workpiece holding unit and configured to shift the tool holder by an operation of causing the driven-side shifting member to be driven by the drive-side shifting member.

A transfer mechanism includes a rail, first and second tables on the rail, first and second arms each having a base pivotably supported by the first and second tables, respectively, and first and second drive mechanisms that move the first and second tables along the rail, respectively. The first and second arms are pivotaly connected to each other at a position between a tip side and a base side. Tip side portions of the first and second arms than a connected portion of the first and second arms serve as fingers for holding a workpiece. The first and second drive mechanisms independently move the first and second tables, respectively. A relative movement of the first and second tables causes the first and second arms to operate a clamp/unclamp operation. A coordinated movement of the first and second tables causes the first and second arms to perform an advance/return operation.
