A loading/unloading robot includes an arm unit attached to a support unit that is capable of being raised and lowered and a hand unit for conveying a loaded/unloaded object, attached to the arm unit. The support unit includes a base portion capable of revolving around a raising/lowering axis and a head portion rotatably attached to the base portion. The arm unit includes arms that are rotatably attached to the head portion. Front ends of the arms move forward and backward along a forward/backward direction that passes the head portion. The hand unit includes a loading/unloading hand rotatably attached to the arm. A center distance from the rotational axis of the head portion to the rotational axes of rear arms is shorter than a center distance from an axis of revolution of the base portion to the rotational axis of the head portion.

摘要:
The present invention relates to an apparatus and a method for transferring substrates into and from a vacuum chamber in a lithography apparatus. The load lock system comprises: a load lock chamber provided with an opening for allowing passage of a substrate in and out of the load lock chamber, and a transfer apparatus comprising a sub-frame at least partially arranged in the load lock chamber, an arm which is, with a proximal end thereof, connected to the sub-frame, and a substrate receiving unit which is connected to a distal end of the arm. The arm comprises at least three hinging arm parts, wherein a first and a second arm part are hingedly connected to the sub-frame with a proximal end thereof. A third arm part is hingedly connected to the distal ends of the first and second arm parts. The arm parts are arranged to form a four-bar linkage.

[Object] To provide a drive device rigid enough to endure a stress due to a reaction during driving of an arm unit, and to provide a conveyance device including the same. [Solving Means] A drive device 50 includes a frame 60 and an actuator 70 installed in the frame 60. The frame 60 is formed by integral molding by casting. The frame 60 includes a connecting portion 61 connectable to a division wall of a conveyance chamber, a bottom plate portion 62 serving as an opposed portion provided to be opposed to the connecting portion 61, and a plurality of coupling portions 63 that couple the connecting portion 61 and the bottom plate portion 62 to each other. The actuator 70 includes three coaxial shafts 75 (two rotating shafts 71 and 72 and single turning shaft 73), three motors 74, and a transmission mechanism that transmits a rotational driving force by the three motors 74 to the three shafts 75. The frame 60 is formed by the integral molding, and hence it is possible to realize a drive device 70 having a high rigidity.

Apparatus for automatically unstacking a pallet (P) on which at least two stacks of blanks (B) are arranged. The apparatus comprises an unstacking station (12) which is configured for receiving a pallet (P) on which are arranged at least two stacks of blanks (B) in collapsed condition. The unstacking station (12) is further configured for taking off one by one individual blanks (B) from the at least two stacks of blanks (B) which are on a pallet (P) received in the unstacking station (12). The apparatus further includes a feed track (14) for conveying pallets (P). The feed track (14) links up by a discharge end with the unstacking station (12) for the purpose of feeding a pallet with stacks of blanks (B) to be unstacked to the unstacking station (12). Further, the apparatus includes a blank main discharge assembly (16) for discharging individual blanks (B) to a further processing station.
