FIG. 3 is a sectional view of a panel transfer apparatus according to an embodiment of the present invention. FIG. 4 is a cross-sectional view of a transfer module of a panel transfer apparatus according to an embodiment of the present invention. FIG.

In the panel transfer device 100 of this embodiment,

An air floating module (10) arranged in the direction of conveyance of the panel (200);

A transfer module (20) disposed around the air floating module (10) for transferring the panel (200);

A vacuum adsorption module 30 disposed at a distal end of the air floating module 20 to adsorb a lower portion of the panel 20;

A transport module 40 disposed below the vacuum adsorption module 30 to move the vacuum adsorption module 30;

And a panel alignment module 50 disposed adjacent to the vacuum adsorption module 30 to align the panel 200.

The panel 200 may be in the form of a glass plate. The panel 200 is generally rectangular in shape. The panel 200 may be a general industrial material.

The air floating module (10)

A body portion 11;

An air movement space 12 formed inside the body portion 11;

An injection hole 13 formed in the upper part of the body part 11;

And a ball 14 coupled to the inner wall of the injection hole 13 with a clearance space.

3 (a), air pressure acts on the air movement space 12 at normal times, and the ball 14 is pushed upward. As a result, the injection hole 13 is closed and air is not blown to the outside. However, as shown in FIG. 3 (b), when the panel slightly presses the upper portion of the ball 14, air is injected into the injection hole 13 through the clearance space. Therefore, the panel can be pushed upward by air pressure. That is, air is injected into the injection hole 13 even if the ball 14 is pushed.

In the upper part of the body part 11, a large number of spray holes 13 are formed in a checkerboard arrangement. When the panel moves on the upper part of the injection hole 13, only the ball 14 of the injection hole 13 at the lower part thereof is pushed and air is injected therebetween. Therefore, air is ejected from the ejection holes in the area where the panel is not positioned. In such a panel transfer apparatus 100, even if an air pump having a capacity smaller than that of the prior art is supplied to the air movement space 12, the panel can be sufficiently floated.

On the other hand, even if manufactured precisely, the amount of air injected from each of the injection holes 13 is different. The air pressure to be injected differs depending on the manufacturing error and the distance and position with the air pump. Therefore, it is preferable that a means for correcting this is provided.

A guide plate 15 having a guide hole 151 formed at a position corresponding to the injection hole 13 is coupled to the lower portion of the injection hole 13 to solve this problem. The guide plate 15 may be integrally coupled to the inner wall of the body portion 11 or may be coupled to the inner wall of the body portion 11 by processing a separate plate member.

A projecting portion 16 is formed on the bottom surface of the air movement space 12 at the lower portion corresponding to the injection hole 13. Further, the guide tube (17) is engaged with the inner wall of the guide hole (151). The guide tube 17 can be adjusted in position to be coupled with the inner wall of the guide hole 151.

The guide hole 151 and the guide pipe 17 may be screwed together. When the guide tube 17 moves in the direction of the bottom surface of the air movement space 12, the distance from the projection 16 is narrowed. In this case, the amount of air injected into the injection hole 13 through the guide pipe 17 is reduced. The distance between the guide pipe 17 and the protrusion 16 can be adjusted after the panel transfer device 100 is formed so that the amount of air injected through the injection holes 13 at each position can be adjusted afterwards.

The transfer module 20 may be formed on the body portion 11 of the air floating module 10. The transfer module 20 can push the lower part of the panel 200 in a specific direction by spraying air. The transfer module 20 includes an inclined hole 21, a vertical hole 22 formed in the body 11, a connection hole 231 formed in the vertical hole 22, (23) protruding from the surface of the body part (11) by air pressure inside the body part (12). At this time, the connection hole 231 is not connected to the inclined hole 21 when the protruding bar 23 protrudes upward. However, when the protruding bar 23 is depressed, the height of the inlet of the inclined hole 21 becomes equal to the height of the outlet of the connection hole 231 so that air can flow from the connection hole 231 to the inclined hole 21 do. As a result, high-pressure air in the air movement space 12 is discharged to the outside through the inclined holes 21. [ The air discharged to the inclined hole 21 pushes the lower part of the panel 200 to be inclined so that the panel 200 is moved. That is, when the protruding bar 23 is pressed by the panel 200, air is injected into the inclined hole 21, and when the protruding bar 23 is not pressed normally, air is blown into the inclined hole 21 It is not sprayed.

In another embodiment, the conveying module 20 may be in the form of a roller and may push the panel 200 with the rotational force of the roller. As a result, the panel 200 moves in a direction to proceed.

The vacuum adsorption module 30 is disposed at the distal end of the air floating module 20. When the panel 200 moves to the upper portion of the vacuum adsorption module 30, the vacuum adsorption module 30 adsorbs and fixes the panel 200.

On the other hand, the panel alignment module 50 is disposed adjacent to the vacuum adsorption module 30 to align the panel 200. The panel 200 should be aligned in the correct posture before entering the processing apparatus. The panel alignment module 50 catches the edge of the panel 200, and the transferred panel 200 is aligned.

The transport module 40 is disposed under the vacuum adsorption module 30. The transport module 40 moves the vacuum adsorption module 30. The transport module 40 may be a conveyor system or a combination of a linear gear and a motor.

The panel 200 moving in the advancing direction is aligned by the panel alignment module 50 to the transport module 40 and the panel 200 is adsorbed by the vacuum adsorption module 30 And is fixed. The transport module 40 then moves the panel 200.

A guiding module 60 is coupled to the outer circumference of the air floating module 10 in the longitudinal direction to guide the edge of the panel 200.

The panel transfer apparatus 100 according to the present embodiment floats the panel 200 with air pressure only at the portion where the panel 200 is located. As a result, the panel 200 can be sufficiently lifted by using an air pressure pump of a smaller capacity than the conventional one.

The term "lifted " in the present embodiment means a state in which the weight of most of the panels 200 pushes up the air injected from the injection holes 13 even if the panel 200 slightly presses the balls 14 do.

Further, the "ball" in this embodiment does not mean the shape of a perfect sphere. Furthermore, the ball 14 of the present embodiment is a concept including that the shape of the upper only ball (hemispherical shape) is also included. The "ball" also includes a shape in which the upper portion protrudes positively.

The "panel" of this embodiment can be made of glass, metal, plastic, or any other material.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Modifications and additions by those skilled in the art to an equivalent range based on the embodiments will also fall within the scope of the present invention.
