Abstract:
A substrate transfer system includes a substrate transfer robot disposed in a robot installment area defined between a first apparatus and a second apparatus. The first apparatus includes cassettes. The cassettes are each configured to accommodate at least one substrate. The second apparatus includes a second wall opposite to a first wall. The substrate transfer robot transfers the at least one substrate from each of the cassettes to the second apparatus. The substrate transfer robot includes a base stationary, a hand, and arms. A first arm includes a first end and a second end. The first end is rotatably coupled to the base. A second arm includes a third end and a fourth end. The third end is rotatably coupled to the second end. The second end of the first arm moves beyond the second wall when the substrate transfer robot takes out the substrate from the first apparatus.
Abstract:
A suction structure includes a fixing base, a pad fixed to the fixing base and a seal member arranged between the pad and the fixing base. The pad includes a contact portion arranged to make contact with a target object to be sucked, a space surrounded by the contact portion, a suction hole through which the space communicates with a vacuum source via the seal member, and one or more support portions fixing the pad to the fixing base. Each of the support portions is arranged on an axis of tilting movement, and being provided with a twist portion for supporting the contact portion such that the contact portion makes the tilting movement about the axis.
Abstract:
A suction structure includes a fixing base, a pad, and a support body. The pad includes a contact portion which makes contact with a target object to be sucked. The support body is installed to the fixing base and the support body is configured to elastically support the pad. Further, the pad and the support body define an inner space, and the fixing base includes a suction hole which brings the inner space into communication with a vacuum source.
Abstract:
A suction structure includes a pad and a fixing base. The pad includes a contact portion which has a seal wall and makes contact with a target object to be sucked, a major surface portion which is surrounded by the contact portion and defines an inner space in conjunction with the seal member as the contact portion makes contact with the target object, and a thin portion formed in the major surface portion. The fixing base includes a suction hole configured to bring the inner space into communication with a vacuum source and supporting the pad.
Abstract:
A carrier device according to embodiments includes a carrier chamber that is provided with a plurality of connecting holes that are communicated with the outside, an articulated robot that is placed inside the carrier chamber, and a linear moving mechanism that makes at least the arm part of the articulated robot linearly move in a short side direction of the carrier chamber. The bottom end of the arm part of the articulated robot is provided on a base via an arm spindle to be rotatable horizontally and its leading end is provided with a hand that is rotatable horizontally and holds a board to be taken in and out via the connecting holes.
Abstract:
A transmission mechanism includes: a drive pulley which is provided on a drive shaft and has external teeth with a predetermined pitch width; a driven pulley which is provided on a driven shaft and has external teeth with the pitch width; and a belt having internal teeth with the pitch width which engage with the external teeth of the drive pulley and the driven pulley. Further, the belt includes sub-belts having a periodic variation characteristic in which the pitch width varies periodically, and the sub-belts are arranged in a state where phases of the periodic variation characteristic thereof are shifted from each other.
