Abstract

In a multi-joint robot (1) including a first arm member (A1) providing a U-shaped portion (10) composed of two protrusion units (11, 12) parallel with each other, and including a second arm member (A2) connected to two protrusion units of the U-shaped portion so as to be rotated and such that both sides of the second arm member are supported by two protrusion units, the first arm member is formed by two half form portions (31, 32) that are divided between the two protrusion units of the U-shaped portion and are divided on a plane perpendicular to a rotational axis of the second arm member. Moreover, the first arm member includes a coupling unit (45a, 45b) for coupling two half form portions to each other.

Claims

1. A multi-joint robot that comprising a first arm member providing a U-shaped portion formed by two protrusion units parallel with each other, and a second arm member connected to two protrusion units of the U-shaped portion so as to be rotated and such that both sides of the second arm member are supported by the two protrusion units,

wherein the first arm member is formed by two half form portions that are divided between the two protrusion units of the U-shaped portion and are divided on a dividing plane perpendicular to a rotational axis of the second arm member, and

wherein the first arm member includes a coupling unit for coupling the two half form portions to each other.

2. The multi-joint robot according to claim 1, wherein each of the half form portions is formed by two half form sub-portions that are divided by an additional plane parallel with the dividing plane, and

wherein each of the half form portions includes an additional coupling unit for coupling the two half form sub-portions to each other.
