Claim:
Work line module, comprising: a combination of a plurality of work machines for mechanically working a workpiece, non-working facility for not mechanically working the workpiece, wherein at least one work machine in the plurality of work machines is a multifunction work machine mechanically working the workpiece and measuring the workpiece, and a conveying machine including a robot for conveying the workpiece among the work machines and the non-work facility and the workpiece are continuously operated in a series of operations with respect to the workpiece in the work line module, wherein the conveying machine comprises a rail provided along the work machines, the non-work facility; and a carrier on which the workpiece is mounted and a robot having seven axes, wherein the robot is arranged at a location between the work machines and a non-work facility and moved along the rail, and the workpiece is conveyed between the carrier and the work machines or a non-work facility, the work machines and between the work machine and the non-work facility, the conveying robots have no moving function for moving over a floor, the conveying machine has a gripper for gripping and releasing the workpiece by opening and closing fingers, and an arm portion for being gripped and released by the gripper provided at a carrier, wherein in the case that the gripper of the robot cannot directly grip the workpiece on a carrier, the gripper of the conveying robot grips the arm portion provided at the carrier trucked on a rail and conveys the carrier so as to move the workpiece to a location where a conveying robot having a moving function can directly grip the workpiece on the carrier.
