The aspects and advantages and/or aspects and advantages of the exemplary embodiments of the present invention will be apparent from the description of the accompanying drawings.

The exemplified embodiments of the present invention are described in detail with reference to the accompanying drawings. The embodiments are described below with reference to the drawings to explain the invention.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the glass substrate transfer apparatus according to the present invention comprises a conveyor 10 for conveying a plate-shaped glass substrate G in a vertical state, and a loading unit 20 disposed on one side of the conveyor 10, The glass substrate G is switched from a horizontal state to a vertical state and the glass substrate G is loaded into the conveyor 10, and an unloading unit 30 disposed on the other side of the conveyor 10, which unloads the glass from the conveyor 10. The substrate G is switched from a vertical state to a horizontal state.

The conveyor 10 includes a carrier 11 shaped to correspond to an outer end portion of the glass substrate G to load the vertical state glass substrate G, and a movably supporting the upper end of the carrier 11 to guide the carrier 11 to move. a transport track 12, and a conveyor frame 13 supporting the carrier 11 when the loading unit 20 and the unloading unit 30 load and unload the glass substrate G from the carrier 11, wherein the transport track 12 The opposite ends are respectively installed on The upper portion of the conveyor frame 13. In this case, the splint 11a is disposed at the outer end portion of the carrier 11 to support the glass substrate G by embedding the outer end portion of the glass substrate G into the splint 11a. In this embodiment, the splints 11a are respectively disposed on the upper end, the lower end and the opposite ends of the carrier 11 to support the upper end, the lower end and the opposite ends of the glass substrate G.

The opposite ends of the transfer track 12 are disposed on the upper portion of the conveyor frame 13 as described above. The loading unit 20 and the unloading unit 30 are respectively disposed on opposite sides of the conveyor 10, that is, opposite sides of the conveyor frame 13. The loading and unloading of the glass substrate G is performed in a single conveyor frame (i.e., the conveyor frame 13). Therefore, the glass substrate transfer device occupies a small area due to its compact configuration.

The loading unit 20 and the unloading unit 30 include turrets 21 and 31 that rotate the glass substrate G from a horizontal or vertical state to a vertical or horizontal state, and adsorb one surface of the glass substrate G such that when the glass substrate G is rotated by the turntable 21 The adsorption units 22 and 32 which are rotatable with the turntables 21 and 31 when supported by 31, and the loading unit frames 23 and 33 of the transfer stages 21 and 31 and the adsorption units 22 and 32 are rotatably mounted thereon, respectively.

The turntables 21 and 31 include a plurality of rollers 21a and 31a that movably support the glass substrate G. The turntable 21 included in the loading unit 20 rotates the glass substrate G from a horizontal state to a vertical state to load the glass substrate G into the carrier 11. The turntable 31 included in the unloading unit 30 rotates the glass substrate G vertically disposed in the carrier 11 from a vertical state to a horizontal state to unload the glass substrate G from the carrier 11.

The adsorption units 22 and 32 are maintained by vacuum pressure transmitted from the outside. The glass substrate G is supported by the turntables 21 and 31. The adsorption units 22 and 23 are attached to the back surfaces of the turntables 21 and 31 on which the glass substrate G is placed on the front surface to move forward and backward with respect to the glass substrate G. The adsorption units 22 and 32 include a plurality of adsorption portions 22a and 32a which adsorb a surface of the glass substrate G by vacuum pressure transmitted thereto. Therefore, when the adsorption units 22 and 32 are moved toward the glass substrate G, the adsorption portions 22a and 32a are in contact with one surface of the glass substrate G in a space between the rollers 21a and 31a to adsorb the glass substrate G. One of the surfaces. Therefore, when the glass substrate G is supported by the turntables 21 and 31, it can be rotated by the turntables 21 and 31.

Further, in order to prevent the stages 21 and 31 and the adsorption units 22 and 32 from colliding with the glass substrate G or the carrier 11 during the rotation, the guide rails 24 and 34 are disposed at the lower portion of the loading unit 20 and the unloading unit 30 so that the loading unit frame 23 And 33 can move forward and backward relative to the carrier 11. Therefore, the loading unit frames 23 and 33 can be moved forward and backward with respect to the carrier 11 along the guiding rails 24 and 34. Therefore, the turntables 21 and 31 and the adsorption units 22 and 32 can be rotated when spaced apart from the carrier 11. Thereby, it is possible to prevent the turntables 21 and 31 and the adsorption units 22 and 32 from colliding with the glass substrate G or the carrier 11.

The operation of the glass substrate transfer apparatus having the above configuration according to the present invention will hereinafter be described in detail with reference to the drawings.

First, the case where the glass substrate G is loaded into the carrier 11 by the loading unit 20 will be explained.

As shown in FIG. 3, the glass substrate G to be processed is transferred to the turntable of the loading unit 20 in a horizontal state via the first conveyor belt C1. The adsorption portion 22a of the adsorption unit 22 mounted on the loading unit 20 is adsorbed and placed on The glass substrate G on the turntable 21 of the loading unit 20 is supported by the turntable 21 of the loading unit 20 by the glass substrate G. In this state, the turntable 21 of the loading unit 20 is rotated as shown in FIG. 4 to position the glass substrate G in a vertical state. The loading unit frame 23 on which the turntable 21 of the loading unit 20 is mounted is advanced along the guide rail 24 toward the conveyor frame 13. The glass substrate G supported by the turntable 21 of the loading unit 20 is loaded into the carrier 11 by the conveyor frame 13. After the glass substrate G is loaded into the carrier 11, the turntable 21 of the loading unit 20 returns to its original position as shown in FIG. The glass substrate G loaded in the carrier 11 is processed while moving along the transport track 12.

Next, the case where the glass substrate G is unloaded from the carrier 11 by the unloading unit 30 will be explained.

When the processed glass substrate G reaches the conveyor frame 13 along the conveying track, the turntable 31 of the unloading unit 30 is rotated as shown in Fig. 5 to dispose the glass substrate G in a vertical state. The loading unit frame 33 on which the turntable 31 of the unloading unit 30 is mounted is advanced toward the conveyor frame 13 along the guiding track. Therefore, the drum 31a of the turntable 31 comes into contact with the glass substrate G loaded in the carrier 11. In this state, the adsorption portion 32a of the adsorption unit 32 mounted on the unloading unit 30 is advanced toward the conveyor frame 13 to be adsorbed to the glass substrate G, whereby the glass substrate G is supported by the turntable. In this state, the loading unit frame 33 on which the turntable 31 of the unloading unit 30 is mounted is moved rearward from the conveyor frame 13 along the guide rail 34 of the unloading unit 30, and then the turntable 31 of the unloading unit 30 is rotated. Therefore, the glass substrate G is rotated from the vertical state to the horizontal state to be transferred to the second conveyor belt C2.

Although an embodiment of the invention has been shown and described, those skilled in the art It is to be understood that modifications may be made in this embodiment without departing from the spirit and scope of the invention.
