Abstract

The invention provides a robot capable of achieving miniaturization. The robot (100) is characterized by being equipped with a first member (41), a second member (42) which is provided on a first member (41) and rotates around a rotation shaft (J2), a driving unit (65) which is provided in the second member (42), and an action shaft (61) which is driven by the driving unit (65) and is provided in the second member (42); and the first member (41) includes a first portion and a second portion which has a smaller width than that of the first portion, when seen in a direction orthogonal to a plane including the rotation shaft (J2) and the action shaft (61), and the second member is connected to the second portion.

Description

technical field [0001] The present invention relates to robots. Background technique [0002] As one type of industrial robot, for example, a suspended SCARA (Selective Compliance Assembly Robot Arm) type robot described in Patent Document 1 and installed suspended from a ceiling surface is known. [0003] The SCARA-type robot described in this patent document 1 has: a base (base) fixed to the ceiling surface, a first arm connected to the base and capable of rotating in a horizontal plane, and a first arm connected to the first arm capable of rotating in a horizontal plane. The second arm of the second arm and the action axis of the tool for conveying the workpiece (component) and the like are installed on the front end of the second arm. In addition, a motor and a reducer for driving an operation axis are fixed to the second arm of the SCARA-type robot. [0004] However, in such a hanging SCARA robot, further downsizing is desired for the purpose of saving space, for exam...
