A copper alloy powder is a copper alloy powder for additive manufacturing. The copper alloy powder contains more than 1.00 mass % and not more than 2.80 mass % of chromium, and a balance of copper. A method for producing an additively-manufactured article includes a first step of preparing a copper alloy powder containing more than 1.00 mass % and not more than 2.80 mass % of chromium and a balance of copper and a second step of producing the additively-manufactured article from the copper alloy powder, and the additively-manufactured article is produced such that forming a powder layer including the copper alloy powder, and solidifying the copper alloy powder at a predetermined position in the powder layer to form a shaped layer are sequentially repeated to stack such shaped layers to thus produce the additively-manufactured article.

Copper alloy powder, method of producing additively-manufactured article, and additively-manufactured article

A metal powder for additive manufacturing includes: not less than 0.2 mass % and not more than 1.3 mass % of aluminum; and a balance including copper and an incidental impurity.

Metal powder, method of producing additively-manufactured article, and additively-manufactured article

A metal powder contains not less than 0.10 mass % and not more than 1.00 mass % of at least one of chromium and silicon, and a balance of copper. The total content of the chromium and the silicon is not more than 1.00 mass %. In accordance with an additive manufacturing method for this metal powder, an additively-manufactured article made from a copper alloy is provided. The additively-manufactured article has both an adequate mechanical strength and an adequate electrical conductivity.

A transfer robot includes a machine base, at least one hand for holding a workpiece, a hand moving mechanism for moving the hand horizontally reciprocally at least in an X direction, a first arm pivotally connected to the machine base for rotation about an axis extending in the X direction. The robot further includes an intermediate arm pivotally connected to the first arm for rotation about another axis extending in the X direction, a second arm pivotally connected to the intermediate arm for rotation about a further axis extending in the X direction. The second arm is also connected to the hand moving mechanism which is rotatable about a still another axis extending in the X direction. A driving mechanism is provided for rotating the first arm, the second arm, the intermediate arm and the hand moving mechanism about the respective axes.

Three-dimensionally movable transfer robot

A two-armed transfer robot is provided which includes an upper arm mechanism and a lower arm mechanism which is substantially identical to the upper arm mechanism. Each arm mechanism is provided with a handling member for carrying a workpiece to be processed. Each arm mechanism is also provided with a pantograph assembly consisting of a base arm, an outer link, a pair of intermediate links and an inner link. The handling member of each arm mechanism is arranged to be spaced from a central driving shaft when the handling member is retreated closer to the shaft. The base arm of the pantograph assembly is inclined away from the handling member when the handling member is retreated closer to the shaft. At the same time, the intermediate links are also inclined away from the handling member.

Two-armed transfer robot

A two-armed transfer robot is provided which includes a first double-pantograph mechanism and a second double-pantograph mechanism which is substantially similar in arrangement to the first double-pantograph mechanism. Each double-pantograph mechanism includes a first pantograph assembly and a second pantograph assembly. The first pantograph assembly is provided with an inner link, a pair of first intermediate links and an outer link. The second pantograph assembly is provided with the outer link in common with the first pantograph assembly, a pair of second intermediate links and a hand-supporting link. The transfer robot also includes a stationary base member, first to fourth shafts coaxially supported by the base member for rotational movement about a vertical axis, first to fourth driving devices for actuating the first to the fourth shafts, respectively. The driving devices are fixed to the base member. The transfer robot further includes first and second handling members supported by the hand-supporting links of the first and the second double-pantograph mechanisms, respectively. The first and the second intermediate links of each double-pantograph mechanism is inclined beyond the vertical axis in a direction opposite to the handling member when the handling member is retreated closer to the shafts.

A two-armed transfer robot includes a first arm mechanism and a second arm mechanism. Each arm mechanism has a handling member for carrying a workpiece. The robot further includes a stationary base member and four shafts rotatable about a common vertical axis. Driving devices for the respective shafts are attached to the base frame. The first and second arm mechanisms are actuated upon rotation of the shafts driven by the driving devices. When the shafts are rotated in a same direction, the handling members of the arm mechanisms are caused to pivot about the common vertical axis. When the shafts are rotated in opposite directions, the handling members are caused to linearly move toward or away from the axis. The two arm mechanisms are vertically spaced from each other, so that they do not interfere with each other.
