Abstract
A device and a method for detecting states of a linear guideway including a sliding block and a slide rail are provided. The device includes a sensor located at a position corresponding to a side surface of the slide rail, and an analysis processer communicated with the sensor. The sensor detects the vibrating of the slide rail to generate a sensing signal. The analysis processer compares the sensing signal with at least one threshold, to determines occurrence of abnormalities. Therefore, the sensitivity for detection may be increased.

A device for detecting states of a linear guideway, the linear guideway including a sliding block and a slide rail, the sliding block including an accommodating groove for accommodating the slide rail, the sliding block being disposed in the accommodating groove and further including two opposite side surfaces, the slide rail including two opposite side surfaces respectively corresponding to the two side surfaces of the sliding block, and the device comprising:
- at least one sensor located at a position corresponding to the side surface of the slide rail, and configured to detect vibration of the slide rail to generate a sensing signal;
- and
- an analysis processor communicatively connected to the at least one sensor to determine occurrence of an abnormality according to a level of the sensing signal and at least one threshold.
