A work hand apparatus (1) is connected to the leading end of an arm (21) of a robot (20) and transfers a work (W) by turns and retraction of the arm (21). The work hand apparatus is provided with a frame (2); reference pins (3a, 4a, 5a) for aligning the work (W) with the frame (2); clampers (3b, 4b, 5b) incorporated with the reference pins (3a-5a) for holding the work (W); and first, second third pin clamper units (3, 4, 5) having the reference pins (3a-5a) and clampers (3b-5b), respectively. The work hand apparatus is further provided with a first driving means (6) for aligning the first pin clamper unit (3) to be freely moved in an X axis direction; a second driving means (7), which aligns the second pin clamper unit (4) and the third pin clamper unit (5) to be freely moved in a Y axis direction that orthogonally intersects with the X axis; and a third driving means (8) for aligning the second pin clamper unit (4) and the third pin clamper unit (5) in a Z axis direction that orthogonally intersects with the X axis and the Y axis. Thus, versatility of the work hand apparatus is improved.
A correction part (67) with a correction head is fitted to the robot arm (20a, 21a) of a correction robot (20, 21). Sash-mounting position measurement sensors (50, 51) for measuring the mounting position of the sash (S) of a door (D1) fixed to a jig device (15) are fitted to the jig device (15). The sash mounting position measurement sensors (50, 51) are connected to a robot control device. When the mounting position of the sash (S) provided by the sash mounting position measurement sensors (50, 51) is out of a predetermined tolerance range, the robot control device moves the robot arms (20a, 21a) to move the correction part (67).
An integrated forming, assembly and inspection system includes a plurality of robotic material conveyors. The integrated system also includes a forming subsystem including sheet metal drawing apparatus, a roller hemming subsystem, and an inspection subsystem. The plurality of robotic material conveyors are operable to convey assembly workpieces to and from the subsystems.
