Abstract

In the suction equipment for a display panel according to the present invention, a plurality of suction ports and a first vacuum line are formed on the upper surface of a main body, the suction ports and the first vacuum line are communicated through a second vacuum line, a suction pipe is connectedly arranged at each of a plurality of suction conduits communicated with the suction ports, thus enabling a porous plate formed with plural through holes to be closely fixed to the upper surface of the main body; accordingly the suction pressure generated in each suction conduit may be used to produce a suction force at the suction ports, the first vacuum line, and the second vacuum line. This suction force is used to forcefully intake air via the plural through holes of the porous plate, thereby sucking a large glass plate placed on the upper surface of the porous plate. Accordingly this invention has the following advantages: the plural suction ports may be individually started up by allowing them to be communicated with a plurality of suction conduits different from each other, even if any of the plural suction ports is damaged or clogged, because a suction port different from the damaged suction port may form a suction force via the suction conduits different from each other, nothing will be affected by the damaged suction port, and because of the formation of a separate suction conduit, the suction force generated at the plurality of suction ports is constant; when a suction port is damaged or clogged, operation can be resumed quickly by replacing the porous plate; a simple replacement of the porous plate can make it easier to maintain and reduce replacement costs, thus increasing the reliability of the product.

Description

Display panel adsorption device

The present invention relates to an adsorption device, and more particularly to an adsorption device for adsorbing a display panel of a large flat glass or a large tempered glass plate.

Generally, a display panel for a smart phone, a tablet (PC), or a touch screen television (TV) is manufactured by cutting a single large flat glass into a plurality of sizes.

At this time, a single large flat glass is difficult for the operator to hold and move due to its size, and in a program in which a group of workers hold and move a large flat glass, there is a large flat glass falling due to a miss. The danger of falling to the ground, so that the two ends of the flat glass are mainly supported by rollers, and the above rollers are driven to transfer the flat glass.

However, if the flat glass is moved by the roller in the manner as described above, sagging occurs in the central portion of the flat glass, causing deformation or damage of the flat glass, and is generated at the bottom surface portions of both ends of the flat glass supported by the roller. scratch Traces and so on.

Patent Document 1 describes a conventional substrate adsorption device for a display panel. Referring to Patent Document 1, the substrate adsorption device for a display panel includes an adsorption panel that forcibly sucks in air through a plurality of adsorption holes formed in a bottom surface of the adsorption panel. The cushioning airbag is disposed above the suction panel, forcibly sucks in and discharges air through the inflow hole and the outflow hole, and the bracket is provided on the upper surface of the cushioning airbag.

At this time, the adsorption panel has a hollow portion that communicates with the adsorption hole, and the adsorption panel forcibly sucks air through the hollow portion to generate an adsorption force in the adsorption hole, thereby adsorbing the substrate on the bottom surface of the adsorption panel.

Here, when the inclination of the suction panel that is in close contact with the substrate is inclined in one direction, air is injected or forcedly discharged through the inflow hole and the outflow hole of the buffer airbag, so that the adsorption panel and the substrate are on one horizontal line. .

However, according to Patent Document 1 as described above, there is a problem that since the adsorption holes communicate with each other through the hollow portion, when a plurality of adsorption holes of the plurality of adsorption holes are blocked or damaged, the forced suction pressure of the air is concentrated on Other suction holes, so that a concentration of suction pressure is generated in a part of the substrate or the glass, and the hollow portion having a predetermined area is maintained in a vacuum state, but since the air is forcibly sucked through the adsorption holes, a relatively high suction pressure is required, and when the adsorption panel is used When it is damaged, the reliability of the product is degraded due to the burden of replacing the entire adsorption panel.

Further, in the case where the tempered glass G erected at a predetermined angle by the above-described rotating device 10 is cut by a cutting device (for example, a sand blasting device), dust, medium, and the like are generated in the process of cutting the tempered glass G described above. Fragments, etc., part of the dust, medium and multiple fragments The through hole 201 of the orifice plate 200 flows into the above-described suction duct 102.

At this time, the dust, the medium, and the plurality of debris flowing into the suction duct 102 enter the vacuum space 111 of the suction duct frame 110, and are filtered by the filter 112 provided in the vacuum space 111, thereby blocking the dust. The medium and the plurality of pieces flow into the suction pump (not shown) provided outside through the suction pipe 300.

That is, the dust, the medium, and the plurality of chips are filtered by the filter 112 to prevent the dust, the medium, and the plurality of fragments from flowing into the suction pump (not shown), thereby preventing the suction pump (not shown) from being dusty, medium, and A piece of debris is damaged or a mechanical failure.

The tempered glass G is adsorbed by forcibly sucking in air through the through holes 201 of the perforated plate 200 by the suction force formed at the first vacuum line 103 and the second vacuum line 104 as described above, and the steel is firmly fixed by the fixing jig 120. Both ends of the glass G are filtered, and the structure of the foreign matter contained in the forcibly sucked air is filtered by the filter 112, and the plurality of suction ports 101 are communicated with the respective suction pipes 102 that are different from each other to be individually activated, even if multiple suctions are performed. One of the port 101 or the through hole 201 is damaged or blocked, but since the suction port 101 or the through hole 201 which is different from the damaged suction port 101 or the through hole 201 forms suction force by the suction pipes 102 which are different from each other, Therefore, it is not affected by the damaged suction port 101 or the through hole 201, and since the separate suction duct 102 is formed, the suction force generated at the plurality of suction ports 101 is made constant, when the through hole 201 is damaged or blocked. The operation can be quickly resumed by replacing the perforated plate 200, and maintenance can be facilitated by simply replacing the perforated plate 200, and the replacement cost can be reduced.

The above description is only for the display surface for implementing the present invention. The embodiment of the present invention is not limited to the above-described embodiments, and the technical idea of the present invention is applicable to the technical field to which the present invention pertains without departing from the gist of the present invention within the scope of the claimed invention.
