Problems solved by technology

Therefore, it takes labor and time to replace the robot spline shaft
In addition, since the work of attaching and detaching the far end of the cable to the terminal of the remote terminal control printed circuit board and the work of attaching and detaching the far end of the air pipe to the connection port of the air manifold are required, it costs a corresponding amount of money. labor and time

Abstract

The invention provides a scara robot. The scara robot comprises: an arm that extends in a horizontal direction and is capable of rotating perpendicularly axially around a rotation central part located in one end part in a longitudinal direction of the arm; an operating spindle assembly that is provided detachably to the other end part in the longitudinal direction of the arm; and an external striate member connected to the operating spindle assembly, wherein the operating spindle assembly includes a hollow operating spindle that moves in a vertical direction with respect to the arm, and an internal striate member which is disposed inside the operating spindle and retained in the operating spindle and to which the external striate member is detachably connected. Exchanging operation of the operating spindle of the scara robot is convenient.

Description

technical field [0001] The present invention relates to an articulated robot (SCARA robot) in which a hollow working shaft movable in an up-down direction is provided at the distal end of an arm rotatable in a horizontal direction (around a vertical axis), and when working A linear member including wiring and piping is inserted into the shaft. Background technique [0002] Conventionally, electronic components have been mounted using an articulated robot including an arm and a work axis. Among such articulated robots, there is a robot that has a hollow working shaft so as not to obstruct the movement of the arm by wires and pipes, and the wires and pipes are provided inside the working shaft (for example, Japanese Patent Laid-Open Publication No. 2001). -277178). The robot comprises: a robot support including a robot base; a first arm, which is rotatably arranged on the upper end of the robot support in a horizontal direction (around a vertical axis); a second arm, which i...
