A gantry machine tool includes a pair of vertical uprights joined atop by a transverse beam, on which a tool holder head is slidingly mounted, and a worktable for anchoring a workpiece, above which the tool holder head is movable. Each upright includes a carriage adapted to slide along a longitudinal support structure, which includes a horizontal surface coplanar to the worktable and a lateral surface embedded in the floor and having a guide system for the carriage.

This application relates to a delivery apparatus and an automated assembly line. The delivery apparatus may include: a delivery assembly including a delivery guide rail and a delivery tool, where the delivery tool may be slidably disposed on the delivery guide rail; a docking assembly including a docking drive structure and a docking guide rail, where the docking drive structure may be configured to drive the docking guide rail to move relative to the delivery guide rail so that the docking guide rail is able to dock with the delivery guide rail; and a blocking assembly configured to block the delivery tool on the delivery guide rail before the docking guide rail docks with the delivery guide rail for receiving the delivery tool.

A workpiece transfer device includes a base unit extending in a first direction, a housing unit disposed upright from the base unit in a second direction orthogonal to the first direction, a slide unit disposed at a housed position to be housed in the housing unit, a slide unit-moving mechanism configured to move the slide unit from the housed position, a linear guide unit configured to guide the slide unit in the second direction, and a workpiece grasp unit disposed on a first surface of the slide unit near an end of the slide unit remote from the base unit and configured to grasp a workpiece W. A separation distance between the base unit and an end of the workpiece grasp unit adjacent to the base unit is less than a separation distance between the base unit and the end of the slide unit remote from the base unit.
