Abstract
The present invention provides a glass substrate transmission device and a method for detecting the rotational synchronization of driven shafts. The device comprising: multiple driven shafts, the multiple driven shafts are disposed parallel at intervals along a first direction and each of the driven shafts has a through hole at the first direction; multiple rollers fixed at intervals on the driven shafts for carrying a glass substrate, and rotate with the driven shaft to flow the glass substrate; a reflection; an infrared sensor unit emitting the infrared and receives a reflection light reflected back by an obstacles and emitted by the infrared sensor unit, and determine the rotational synchronization of the driven shafts according to the value of the intensity of the reflected light. The through holes and the reflection plate are located at the propagation direction of the infrared of the infrared sensor unit. By above way, the present invention can timely detect that if the multiple driven shafts rotate synchronously or stop rotating to avoid the glass substrate from scratch or break.
