1. Field of the Invention
Embodiments of the present disclosure relate to display technology, and more particularly to a transportation device of the glass substrate cartridges and a warehouse apparatus.
2. Discussion of the Related Art
Glass substrates are usually temporality stored by glass substrate cartridges in liquid crystal device manufacturing. And the glass substrate cartridges are stored in a serial of warehouse apparatuses forming an automatic transportation system.
Each warehouse apparatus includes cabinets, lifting arms, and transportation devices. The transportation devices connect with the lifting arms and are driven by the lifting arms to move the glass substrate cartridges into the cabinets.
In conventional technology, the transportation device includes bearing arms and positioning mechanisms. In the transportation process, the transportation device moves close to the glass substrate cartridges and then lifts the glass substrate cartridges. The bearing arms hold the glass substrate cartridges and pass through the positioning mechanisms to prevent the glass substrate cartridges from falling in a predetermined direction or in a direction opposite to the predetermined direction.
However, in the above process, the glass substrate cartridges contact the positioning mechanisms rigidly. The glass substrate cartridges collide with the positioning mechanisms when the transportation speed is high or a transportation deviation happens. Such collisions may result in the displacement or fragment of the glass substrates.

Embodiments of the invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown.
As shown in
In one embodiment, the transportation device 100 includes two supporting component 1, wherein one of the supporting component 1 extends along the first horizontal direction X. The supporting components 1 are spaced apart from each other in the second horizontal direction Y. The supporting component 1 is substantially bar-shaped. The transportation device 100 accesses the glass substrate cartridges 200 along the first horizontal direction X. The positioning components 2 elastically positions the glass substrate cartridges 200 along the first horizontal direction X to prevent the glass substrate cartridges 200 from falling from the transportation device 100.
The transportation device 100 may include, but not limited to, one or three supporting components 1. In one embodiment, the transportation device 100 includes one supporting component 1, which is substantially a plate-like structure extending along the first. horizontal direction X and the second horizontal direction Y. In another embodiment, the transportation device 100 includes two supporting components 1, and the supporting components 1 extend along the second horizontal direction Y and are spaced apart from each other in the first horizontal direction X.
In one embodiment, the transportation device 100 includes more than two supporting components 1. The transportation device 100 further includes two connecting components 3 for connecting the supporting components 1. In this embodiment, the supporting component 1 extend along the first horizontal direction X, the connecting components 3 extend along the second horizontal direction Y, and the connecting components 3 vertically connect the two supporting components 1.
The glass substrate cartridges 200 include at least two supporting hats 201 arranged in a bottom of the glass substrate cartridges 200. The supporting bars 201 extend along the second horizontal direction Y and are spaced apart from each other in the first horizontal direction X. Each of the supporting bars 201 is gripped by at least one pair of positioning components 2.
In the embodiment, each of the supporting bars 201 is gripped by the two positioning components 2. The positioning components 2 for gripping, the same supporting bar 201 are respectively arranged on different supporting component 1. A top surface of the supporting component 1 is a hearing surface 10. The positioning components 2 are arranged on the bearing surface 10. Each pair of the positioning components 2 are spaced apart from each other along in the first horizontal direction X. In addition, each pair of the positioning components 2 elastically grips the supporting bars 201 of the glass substrate cartridges 200.
In one embodiment, the number of the positioning components 2 for gripping one supporting bars 201, and the number of the supporting bars 201 are not limited in the disclosure. In other embodiments, the glass substrate cartridges 200 may not include the supporting bars 201.

In other words, for one pair of the positioning components 2, the sliding assembly 23 are spaced apart and arranged close to the other, and the fixing assembly 21 are arranged to be distant from the other.
The sliding assembly 23 includes a guiding portion 231 to smoothly access the glass substrate cartridges 200. Preferably, the guiding portion 231 includes an arc-connected surface. The guiding portion 211 is for guiding the glass substrate cartridges 200 to be carried on the supporting component 1 along a vertical direction. The guiding portion 231 guides the supporting bars 201 to slide into one location between one pair of positioning components 2 and were elastically gripped by one pair of positioning components 2.
In one embodiment, the elastic assembly 22 is a spring. In other embodiments, the elastic assembly 22 may be components made of elastic materials. In addition, the elastic assembly 22 may be integrally formed with the sliding assembly 23 on condition that the positioning components 2 contacts with portions of the supporting bars 201 or the glass substrate cartridges 200.
The glass substrate cartridges 200 elastically contacts with the positioning components 2 when the transportation device 100 carries the glass substrate cartridges 200. As such, the glass substrates within the glass substrate cartridges 200 are not displaced or fragmented due to the buffering effect between the glass substrate cartridges 200 and the positioning components 2.
