Problems solved by technology

[0011] However, the above-mentioned parallel-linked robot has a narrow range of posture change, and also a narrow range of motion in the vertical direction.
[0012] In addition, since the parallel link robot can carry a small weight, the above-mentioned robot with a posture changing mechanism with three degrees of freedom at the front end of the parallel link robot has low rigidity.
Therefore, in the work in which the robot requires motion accuracy, for example, in the work of fitting a part into a recess, the position of the part may deviate and the fitting into the recess may fail.

Embodiment Construction

[0028] Below, based on the attached drawings, while referring to Figure 1 to Figure 7 A robot according to an embodiment of the present invention will be described.

[0029] The robot according to the present embodiment is an industrial robot suitable for assembly work of devices having relatively small components such as personal computers and mobile phones, especially for work requiring operational precision.

[0030] Such as figure 1 As shown, the robot of this embodiment includes a tool shaft 1 , a first support mechanism 2 , a second support mechanism 3 , a first in-plane movement mechanism 4 , a second in-plane movement mechanism 5 , and a control unit 6 .

[0031] Here, the tool shaft 1 is a shaft on which various tools, tables, etc. are attached to the front end 1A. For example, an end effector such as an air chuck, a table for holding a workpiece, and the like are attached to the front end 1A of the tool shaft 1 .

[0032] The first support mechanism 2 is attached...

Abstract

A robot comprises: a tool shaft (1); a first support mechanism (2), mounted on one section of the tool shaft, and tiltably supporting the tool shaft; a second support mechanism (3), mounted on another section of the tool shaft, and tiltably supporting the tool shaft; a first in-plane movement mechanism (4) for moving the first support mechanism in a first plane; a second in-plane movement mechanism (5) for moving the second support mechanism in a second plane; and a controller (6) for controlling the in-plane position and tilt angle of the tool shaft by controlling the first in-plane movement mechanism and second in-plane movement mechanism. The first support mechanism or the second support mechanism supports the tool shaft to be moveable in the axial direction.

Description

technical field [0001] The present invention relates to robots. Background technique [0002] In robots such as industrial robots, high speed, high precision, high degrees of freedom, and a wide range of motion are required. [0003] For example, in high-speed packaging work, etc., a parallel link robot excellent in high speed is used. [0004] In recent years, a robot having a three-degree-of-freedom posture change mechanism at the front end of a parallel link robot has been developed and used for, for example, assembly work.
