摘要:
A compact turning device for a heavy object, comprising a turning arm (11) joined to the heavy object (5) and a drive device (12) drivingly turning the turning arm (11). The drive device (12) further comprises a motor incorporating a rotor shaft connected to the rotating input part of a planetary gear type speed reducer on a same axis (A). Also, the turning arm (11) is installed by joining its first plane to the plane of the planetary gear type speed reducer forming the rotating output part and its second plane orthogonal to the first plane to the heavy object. The turning arm (11) and the drive device (12) are disposed within the width (D) of the heavy object (5) in the axis (A) direction of the turning pivot of the turning arm (11). The planetary gear type speed reducer of the drive device (12) may be disposed in two front and rear stages.
摘要:
A wafer (W) transfer system (E) comprises a host computer (1) for managing the production of semiconductor devices, probers (2) for checking electrical characteristics of the wafer (W) under control by this host computer (1), an AGV (3) for automatically transferring wafers (W) in a carrier to deliver the wafers (W) one by one to these probers (2) in response to the request of each of the probers (2), and an AGV controller (4) for controlling this AGV (3) under control by the host computer.
