[0029] Figure 1 to Figure 3 A SCARA-type robot (planar articulated robot) A which is a robot according to the first embodiment of the present invention is shown. The SCARA robot A includes a base portion 10 , a first arm 18 , a second arm 20 , and an elevating and rotating drive device 30 provided on the second arm 20 .

[0030] The base part 10 is fixedly installed on a floor or a table or the like. Such as image 3 As shown, the base part 10 includes: a rectangular box-shaped housing 11; a motor 12 fixedly arranged on the upper part of the housing 11; and an upper surface part 11a assembled on the upper part of the motor 12 and fixedly arranged on the housing 11 The reducer 13. In addition, in this specification, the front-back direction refers to the image 3 The direction perpendicular to the paper surface (the front side is the front direction), in the following description, the up-down direction and left-right direction are based on image 3 set up.

[0060] Figure 7 and Figure 8 A SCARA-type robot B according to a second embodiment of the present invention is shown. The main difference between the structure of the SCARA robot B and the structure of the SCARA robot A is that instead of the vertical rotation drive device 30 in the SCARA robot A, a vertical rotation drive device 60 having the following structure is provided.

[0061] Lifting rotary driving device 60 comprises cover 61, hollow working shaft 71, working shaft assembly 70 (referring to Figure 9 ), the rotating device 62 for rotating the working shaft assembly 70 around the axis, and the lifting device 65 for moving the working shaft assembly 70 in the vertical direction. Furthermore, a hollow shaft 68 is detachably connected to the upper end portion of the operating shaft assembly 70 . The cover 61 has a box-like shape having two different heights as the covers 31 and 51 of the SCARA robot A are integrally formed, and does not have a portion corresponding ...

[0072] Figure 14 to Figure 18 A SCARA-type robot C according to a third embodiment of the present invention is shown. The structure of the SCARA robot C differs from that of the SCARA robot B in that it has a vertical rotation drive device having the following structure instead of the vertical rotation drive device 60 in the SCARA robot B of the second embodiment.

[0073] Figure 14 to Figure 16 Indicates the connecting portion of the working shaft assembly 80 and the hollow shaft 85, Figure 17 and Figure 18 A connection portion between the working shaft assembly 80 and the manipulator 88 side is shown. The operation shaft assembly 80 has a structure in which connection members 82 and 83 are attached to the upper and lower openings of the hollow operation shaft 81 , respectively, and the connection members 82 and 83 are connected by connection wires 84 a. The operating shaft 81 is constituted by a steel ball spline shaft in which a plurality of vertical grooves 81 a ar...

Abstract

The invention provides a robot. The robot comprises a root part; arms capable of rotating on the horizontal direction with the root part as the center; a hollow working shaft extending along the vertical direction and supported on the arms in a way to be capable of moving axially and rotating around the axis; a driving part driving the working shaft vertically; a hollow shaft connected on the upper end of the working shaft in a way to have the inner side communicated with the inner side of the working shaft; a linear part equipped in a way to pass through the inner sides of the working shaft and the hollow shaft; and a hood equipped on the arms, covering the working shaft and having a through hole for the hollow shaft to pass through in a way to protrude upwards. Thus, the robot provided in the invention is low in price.

Description

technical field [0001] The present invention relates to a robot whose arm can rotate in the horizontal direction, wherein a hollow working shaft is supported at the front end of the arm so as to be able to move up and down and rotate about the axis, and wiring can be inserted into the working shaft and at least one of piping. Background technique [0002] Robots have long been used in the installation of electronic components. In such a robot, in order that the wiring and piping do not hinder the movement of the arm, for example, Japanese Patent Application Laid-Open No. 2001-277178 describes a robot in which wiring and piping are provided inside the working axis. The robot comprises: a robot pillar having a robot base; a first arm capable of rotating horizontally at the upper end of the robot pillar; a second arm capable of rotating horizontally at the front end of the first arm; an installation shaft , disposed at the front end of the second arm; and a hollow robot splin...
