Embodiment Construction

[0017] Hereinafter, embodiments of the robot system disclosed in the present invention will be described in detail with reference to the accompanying drawings. In addition, this invention is not limited to the example in the Example shown below.

[0018] 【Example】

[0019] Hereinafter, a robot system for automatically performing an assembly operation of fitting a gear as a ring-shaped member to a shaft by a robot will be described. In addition, the member fitted to the shaft is not limited to a gear, and may be any ring-shaped member such as a rotor or a pulley.

[0020] figure 1 is a schematic diagram showing the configuration of the robot system 1 of the embodiment. Such as figure 1 As shown, the robot system 1 has: a robot 2, which automatically performs the assembly operation of fitting the gear 7 to the shaft 5; and a control device 3, which is arranged outside the active area 100 of the robot 2, and controls the overall action of the robot system 1. .

Abstract

The present invention provides a robot system. The yield can be improved through assembly operation automatically performed by a robot in the case that annular members are fitted to a shaft. The robot system includes: a robot, gripping the shaft which can install an engagement member on circumferential surface, wherein the engagement member is engaged with the inner circumferential surface of the annular member, so that the shaft is enabled to rotate; a jig used for fixing the annular member; a control portion, under the state that the robot grips the shaft engaged with the annular member, and the contact between the annular member and the jig is enabled, applies a rotational force to the shaft by the robot; and a determination unit, determines whether the engagement member is mounted to the shaft according to the operation of the robot when the rotational force is applied.

Description

technical field [0001] The present invention relates to robotic systems. Background technique [0002] Conventionally, there is a robot system that automatically performs assembly work of components by an industrial robot (hereinafter simply referred to as "robot"). For example, Patent Document 1 discloses a technique in which a robot automatically performs an assembly operation of fitting a ring-shaped member to a shaft. [0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 8-187687 [0004] However, in the technique described in Patent Document 1, the fitting strength between the ring-shaped member and the shaft is not taken into consideration, and therefore there is a problem that the yield decreases when a member requiring fitting strength is assembled. Contents of the invention [0005] The technique disclosed in the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a robot syste...
