ABSTRACT:
A system can be formed for automatically loading and unloading items such as ICs into and from containers of different types having various configurations by providing a plurality of base units each of the same structure but having different item-handling modules attached thereto. The base units have a unistructurally cast planar top plate with a horizontal top surface, an arm which is horizontally supported above the top plate and a driving assembly which serves to move the arm in a horizontal first direction while the arm remains extended in a horizontal second direction perpendicular to the first direction. A holder member is mounted to the arm and slidable therealong in the second direction. A spline shaft is rotatably supported by the top plate that extends in the first direction. A belt is attached to the holder member on the arm and engages with the spline shaft in a power-communication relationship. The belt is slidable along the spline shaft such that, as the spline shaft rotates, the belt can pull the holder member in the second direction independently of the position or motion of the arm in the first direction. Different types of item-handling modules are attached to the individual units for particular loading and unloading operations.
