Background Art

[0002] After the production of liquid crystal glass substrates is completed, the layers of liquid crystal glass substrates are separated by separator paper and stacked on transport racks for transportation. Due to excessive transportation acceleration and deceleration and road conditions, the liquid crystal glass substrates frequently shift as a whole after arrival. When taking the plates from the transport racks, the suction cups of the plate-taking robot cannot completely absorb the shifted liquid crystal glass substrates or the suction cups are too close to the edges of the liquid crystal glass substrates, resulting in uneven force on the liquid crystal glass substrates and breakage.

[0003] The current method for dealing with the offset of the stacked liquid crystal glass substrates on the transport rack is to manually lift the substrate, which has the following disadvantages:

[0004] 1. Lifting the board requires multiple people to do it at the same time and it takes a long time, resulting in high labor costs;

[0005] 2. The placement accuracy of the board during manual lifting is not enough, and it is easy to cause the liquid crystal glass substrate to be contaminated or high particle generation affects the quality of the liquid crystal glass substrate;

[0006] 3. When the plate is lifted manually, the different stress points of the liquid crystal glass substrate or the lack of synchronization of the lifters may easily cause the liquid crystal glass substrate to break and cause losses. Utility Model Content
