[0073] Figure 12 and Figure 13 An articulated robot C according to a second embodiment of the present invention is shown. This articulated robot C is an articulated robot in which the layout of the wiring and piping 70 (hereinafter referred to as wiring and the like 70 ) connected to the wiring and the like 16 extending through the flexible tube 15 in the above-mentioned articulated robot A is changed, Parts other than the mounting structure of the wiring etc. 70 are the same as those of the articulated robot A. Therefore, the same reference numerals will be attached to the same parts for description.

[0074] In this articulated robot C, the wires and the like 70 extend from the lower right side portion of the upper surface of the cover 31 to the upper end of the connecting shaft 32c. The base end portion of the wiring etc. 70 is fixed by a connection member 71 provided on the upper surface of the cover 31 including a wiring connector and a pipe fitting. Proximal end po...

Abstract

Provided is an articulation type robot that makes the up-and-down moving operation shaft to move in the horizontal direction. The articulation type robot comprises a cover member covering the side of the operation shaft, a motor driving the operation shaft, an upper bellows-like member arranged at the upper portion of the cover member and stretching out and drawing back in the up-and-down direction to interlink with the operation shaft, and a lower bellows-like member arranged at the lower portion of the cover member and stretching out and drawing back to interlink with the up-and-down movement of the operation shaft. The inner space of the cover plate and the inner space of the upper bellows-like member are communicated. The inner space of the cover plate and the inner space of the lower bellows-like member are also communicated. The motor is arranged between the upper bellows-like member and the lower bellows-like member. Therefore, the articulation type robot is provided with excellent dustproof and drip-proof property and is capable of preventing the motor from being too heat.

Description

technical field [0001] The present invention relates to an articulated robot (SCARA robot) in which accordion-shaped members are arranged above and below a working axis that moves up and down. Background technique [0002] Conventionally, articulated robots have been used for mounting electronic components. In this articulated robot, it is known that in order to prevent external dust or water droplets, etc. An articulated robot in which bellows-shaped cover members are provided therebetween (for example, Japanese Patent Laid-Open Publication No. Hei 11-138488). [0003] The articulated robot described in this patent document includes a main body arm, a first arm capable of horizontal rotation relative to the main body arm, and a second arm capable of horizontal rotation relative to the first arm. At the far end of the second arm, a ball screw spline capable of moving up and down and rotating is provided, and an antistatic accordion-shaped component is respectively provided...
