摘要:
An apparatus for loading/unloading workpieces, including a furnace heating a workpiece, and a robot loading and/or unloading a workpiece into/from the furnace. The robot may include a manipulator linkage and a fork at an end of the manipulator linkage. The fork may have an upper side on which a workpiece is placed while being loaded into and/or unloaded from the furnace. The fork may include a parallel arrangement of fork elements, each fork element in the fork having a length and rectangular cross section perpendicular to the length. Each fork element may have a workpiece carrying surface on which a workpiece is placed and an opposite surface to the workpiece carrying surface. The fork element may include a heat insulator disposed on the workpiece carrying surface at least over an area where a workpiece is placed to equalize longitudinal thermal expansions in the workpiece carrying surface and the opposite surface.
