Abstract

A single-axis robot in which a ball screw or a linear guide can be easily replaced is provided. A single axis robot, includes: a housing including, on a first side, a base plate having a first saddle hole; a support plate arranged in a second side of the housing; a linear guide arranged inside the housing along the base plate, the linear guide extending along the first saddle hole; a slider arranged inside the housing on the linear guide, the slider configured to slide along the linear guide; a saddle arranged on the first side of the slider to protrude to an outside of the housing through the first saddle hole; a driving device arranged on the second side of the slider to drive the slider; and a telescopic cover arranged outside the housing between the base plate and the saddle.

First claim

What is claimed is:

1 . A single axis robot, comprising:
a housing including, on a first side, a base plate having a first saddle hole; a support plate arranged in a second side of the housing; a linear guide arranged inside the housing along the base plate, the linear guide extending along the first saddle hole; a slider arranged inside the housing on the linear guide, the slider configured to slide along the linear guide; a saddle arranged on the first side of the slider to protrude to an outside of the housing through the first saddle hole; a driving device arranged on the second side of the slider to drive the slider; and a telescopic cover arranged outside the housing between the base plate and the saddle.

2 . The single axis robot according to claim 1 , wherein
the driving device includes
