BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum panel adsorber for glass panels, and more particularly, to a glass panel vacuum adsorber capable of easily adsorbing and detaching a glass panel for LCD or PDP.

Recently, with the introduction of many LCD and PDP products, the production of glass panels used for such applications is gradually increasing. In the production process of the glass panel, an apparatus for directly transporting the glass panel by the operator is essential, and FIG. 1 shows a representative structure of a vacuum adsorber for glass panels in the related art.

As shown, the conventional adsorber has a rubber pad 10 in the shape of a dish upside down, a frame 20 integrally coupled to an upper portion of the rubber pad 10, and a lower end of the rubber pad 10. Coming in the center and the upper end of the connecting rod 30 protruding toward the center of the frame 20, the lever 40 connected to the upper end of the connecting rod 30 so that the connecting rod 30 can be raised and lowered, The handle 50 is fixed to the upper portion.

In the conventional adsorber, when the lever 40 is pressed, the connecting rod 30 is raised and the center of the rubber pad 10 is raised to form a vacuum in the space between the glass A and the rubber pad 10. A) can be adsorbed and lifted up. On the contrary, when the lever 40 is flipped to its original position while the glass A is moved, the center portion of the rubber pad 10 descends while the connecting rod 30 descends to release the vacuum state.

However, such a conventional adsorber has a disadvantage in that it is very cumbersome to use the lever 40 while pressing the rubber pad 10 against the glass A. In particular, since the lever 40 must be operated both at the time of adsorption and separation, it was more inconvenient to operate.

In addition, conventionally, when the connecting rod 30 is lowered to separate the adsorber from the glass A, a vacuum state is formed again, so that the adsorber is hardly removed from the glass A.

The present invention has been made to solve the above problems, the object of the present invention is to provide a glass panel vacuum adsorber that can be easily detached by one-touch by simply pressing the adsorption, and can be separated by pressing a switch operation. have.

Vacuum adsorption

Figure 4 shows the structure at the time of vacuum adsorption of the vacuum panel adsorber for glass panel according to this embodiment.

As illustrated, the rubber pad 100 is flatly deformed by holding the frame 200 by hand while pressing the vacuum absorber on the glass panel A. Subsequently, as soon as the piston for air communication 700 is raised and the O-ring 710 is separated from the inner surface of the guide rod 400, the air of the rubber pad 100 passes through the air hole 150, the through hole 430, and the air communication. The vacuum is formed in the rubber pad 100 by being discharged through the balls 410 in turn.

Of course, after the vacuum is formed, the air communication piston 700 immediately returns to its original position, and the O-ring 710 contacts the inner surface of the guide rod 400 to close the through hole 430.

In this case, the flow of air is indicated by an arrow.

When removed

Next, the action of separating the adsorber from the glass panel A in the vacuum adsorbed state will be described with reference to FIG. 5.

As shown, when the release button 300 is pressed, the ends of the two rods 600 'and 600 "disposed at the bottom thereof are pressed, and each rod is a hinge pin coupling pin 210' and 210". Hinge movement (or lever movement) around the center is the opposite end of the separation button 300 is raised.

Accordingly, the air communication piston 700 installed by being caught on the opposite end of the release button 300 of the rods 600 'and 600 "is raised, and then the O-ring 710 is connected to the inner surface of the guide rod 400. Separated is the state that the outside air is introduced through the through hole 430.

As a result, the vacuum state inside the rubber pad 100 is destroyed and reliably separated from the glass panel A. FIG.

In this case, the flow of air is indicated by an arrow.

The above-described example is only one preferred embodiment, and there can be various modifications apparent to those skilled in the art within the scope of the technical idea described in the claims below.
