Embodiment Construction

[0057] Hereinafter, embodiments of the robot disclosed in the present application will be described in detail with reference to the drawings. In addition, this invention is not limited to embodiment shown below.

[0058] In the following, a robot used for spot welding will be described as an example.

[0059] First, the outline of the robot 10 according to the embodiment will be described. figure 1 It is a perspective view of the robot 10 according to the embodiment. Also, below, for convenience of explanation, the turning position and posture of the robot 10 are basically in the figure 1 The state shown here describes the positional relationship of each part of the robot 10 .

[0060] In addition, in figure 1 In , for easy understanding of the description, a three-dimensional Cartesian coordinate system including the Z-axis with the vertical upward as the positive direction is shown. This Cartesian coordinate system is sometimes also shown in other drawings used for the ...

Abstract

A robot (10) includes: a stage unit (11); a rotation base (12) connected to the stage unit in a rotatable manner around a predetermined rotating axis (S); an arm unit (13) connected to the rotation base and having a base end rotatable around a first rotation axis (L) that is substantially orthogonal to the rotating axis; a balancer (16) connected to both the rotation base and the arm unit; and a cable (17) arranged along the arm unit outside the balancer while supported by that balancer.

Description

technical field [0001] Embodiments disclosed herein relate to robots. Background technique [0002] Conventionally, a robot used for spot welding and the like is known (for example, refer to Patent Document 1). For example, this robot is configured to include: a revolving base provided so as to be rotatable with respect to a base portion fixed on the ground or the like; and a multi-axis arm attached to the revolving base. [0003] In addition, a balancer for gravity compensation is connected to the swivel base. In addition, the balancer mostly adopts a spring-type balancer. [0004] In addition, the equipment cable equipped on the robot is arranged so as to be wound around the outer side of the swivel base, and is further arranged along the multi-axis arm from the outer periphery of the swivel base. [0005] Patent Document 1: Japanese Patent Laid-Open No. 2011-200989 [0006] However, in the prior art described above, there is room for further improvement in terms of sp...
