Steering device and base plate conveying device

Abstract

The invention provides a steering device. The steering device comprises a bearing table arranged between equipment, a steering motor arranged on the lower end of the bearing table, a lifting mechanismarranged on the output shaft of the steering motor and an alignment mechanism; the alignment mechanism comprises leg bases and alignment grooves; the leg bases are fixed on two opposite side edges ofthe bottom of the bearing table; the alignment grooves are arranged at positions corresponding to the leg bases; and when the steering motor finishes steering, the lifting mechanism drives the bearing table to descend, so that the leg bases fall into the alignment grooves, and alignment is finished. The invention further provides a base plate conveying device which comprises a conveying mechanismand a steering device, and the conveying mechanism is arranged on the bearing table. Compared with the prior art, the possibility that a base plate is impacted during continuous conveying to be broken or cracked, so that production cost is lowered.

Description

technical field [0001] The invention relates to a display panel technology, in particular to a steering device and a substrate transmission device. Background technique [0002] At present, in the liquid crystal panel industry, the size of the panel is constantly developing towards a trend of being thinner and larger. Therefore, the size of the glass substrate is required to be larger and larger. The largest panel size currently used in China is the 2940mm×3370mm glass substrate of the G10.5 generation line. The transportation of such a large substrate mainly relies on the substrate transfer device to transfer it. [0003] In addition, sometimes in order to judge which machine produced the defect during the preparation process, it is necessary to turn the glass substrate through the steering device, for example, 90 degrees, and judge the machine that produced the defect by judging the relative position of the defect before and after turning . Therefore, the steering mech...

Problems solved by technology

[0004] However, the steering mechanism must ensure that the centerline position is consistent during the rotation process. If the centerline position is not consistent, after the rotation, the steering mechanism will hit the entrance of the next equipment when the glass substrate is conveyed again, resulting in broken pieces.
