Transmission system of LCD panel and automatic crane thereof

Abstract

The present invention discloses a transmission system of an LCD panel and an automatic crane thereof. The transmission system comprises a guide rail and a transmission apparatus. The transmission apparatus comprises a main body, an alarm unit, a main wheel disposed at the bottom of the main body, and a sensor disposed below the main body. The main wheel abuts to the guide rail so that the transmission apparatus can move along a preset direction of the guide rail. The sensor is for detecting whether the main wheel is abnormal The alarm unit is for generating an alarm when the sensor detects that the main wheel is abnormal. The present can achieve the real-time monitoring for the operation of the main wheel by disposing the sensor in order to timely detect the abnormality and generate an alarm when it is abnormal through the alarm unit.
