Problems solved by technology
In the production process, it is necessary to use the transfer device to transport the substrate to a specific position. Since the thickness of the substrate is only 0.5mm or even thinner, the substrate collides with the transfer device during transportation, often resulting in broken corners or breakage of the glass
Since the damaged location is not fixed, the operator may not be able to detect and stop the equipment in time
As a result, it is easy to cause damaged substrates to enter the downstream equipment of production
In addition, the substrate of the liquid crystal display and the functional patterns on it are mostly transparent materials, and it is difficult to find fragments in the production line at the first time

The invention provides a substrate conveying device which comprises a conveying mechanism, a weighing mechanism, a lifting mechanism, a control mechanism and a processing mechanism. The conveying mechanism is composed of a plurality of conveying rollers. Furthermore a clearance is arranged between two adjacent conveying rollers. The weighing mechanism is arranged on the lifting mechanism and is arranged in the clearance of the conveying rollers. The control mechanism is used for making the elevating mechanism lift, thereby making the weighing mechanism support a to-be-detected substrate on the conveying mechanism and obtain the weight data of the to-be-detected substrate. The processing mechanism can determine whether the substrate is abnormal according to the weight data which are obtained by the weighing mechanism. The substrate conveying device is suitable for an assembly line and can perform quality inspection on the substrate, thereby preventing the damaged substrate or the substrate with residues to downstream equipment, and furthermore preventing yield rate reduction of final products.
Description
technical field [0001] The invention relates to the manufacturing field of display devices, in particular to a substrate conveying device. Background technique [0002] TFT-LCD liquid crystal display uses a glass substrate as a matrix, and forms a specific pattern on the surface of the substrate. During the production process, it is necessary to use a conveyor to transport the substrate to a specific position. Since the thickness of the substrate is only 0.5mm or even thinner, the substrate collides with the conveyor during transportation, often resulting in broken corners or breakage of the glass. Since the location of the damage is not fixed, the operator may not be able to detect and stop the equipment in time. In this way, it is easy to cause damaged substrates to enter the downstream equipment of production. In addition, the substrate of the liquid crystal display and the functional patterns on it are mostly transparent materials, and it is difficult to find fragments...
