Description
Technical Field
The present invention relates to a thin display panel transfer and coating apparatus, and more particularly, to a thin display panel transfer and coating apparatus that performs movement and inkjet coating by vacuum suction of only edges of four sides of a thin display panel of 300 μm or less.
Background
In the conventional display field, an Inkjet Coating (Inkjet Coating) technique is applied to a case where a display panel is made of glass or the thickness of the panel is 500 μm or more, and thus, the corresponding panel can be transferred by using an industrial logistics transfer Robot (Robot).
In general, in the process of vacuum-sucking a panel having a thickness of 500 μm or more by using an industrial transfer robot and then transferring the panel, the phenomenon that orange peel is not generated on the surface of the panel during vacuum suction is not generated during vacuum suction.
That is, in the Inkjet Coating (Inkjet Coating) process, the influence on Orange Peel (Orange Peel) as a cause of the defect is not significant.
However, when the thickness of the display panel is 300 μm or less, or when the flexible display is transferred by using an industrial transfer robot using a general vacuum system, there is a problem in that the flexible display cannot be mounted on the ink coating apparatus.
In particular, a film forming region is formed as an actual coating region on the upper surface of the thin display panel, and a non-film forming region is formed only in the edge region of the panel along the edge of the film forming region.
Thus, when the thin display panel is transferred, only the edge region is used to transfer the thin display panel to the coating region of the coating device. In this case, there is a problem in that the center of the panel sags as the edge region of the thin display panel is sucked.
In addition, in the process of placing the panel on the vacuum chuck disposed in the coating region in vacuum, the panel is placed on the vacuum chuck by using the lift pin module, and there is a problem that uneven ink coating (Mura, uneven coating, and speck) is caused as the panel is adsorbed by a plurality of vacuum.
That is, since the Lift Pin Module (Lift Pin Module) is used in the past, it has been difficult to prevent the uneven phenomenon of the coating layer as described above.

Referring to fig. 5, a heating panel 330 for receiving a current from a current supply (not shown) and heating the current to a temperature within a predetermined range is disposed at a lower portion of the second vacuum chuck 310.
The control part 600 presets different reference heating temperatures according to the kind of the ink.
When the type of the ink is set, the control part 600 may heat the heating panel 330 by using the current supplier in order to achieve the reference heating temperature corresponding to the set type of the ink, thereby supplying heat to the display panel 10 placed on the second vacuum chuck 310.
When the ink coating is completed on the display panel 10 by the coating part 500, the control part 600 vacuum-adsorbs the edge region of the display panel 10 by using the transfer part 400.
Next, the second air supply module 320 is used to supply air to the center portion of the bottom surface of the display panel 10, which is sucked to the edge region, by holding the vacuum supplied to the second vacuum chuck 310.
The display panel 10 having the edge area attached thereto can be unloaded by using the transfer part 400.
Next, the operation of the thin display panel transfer and coating device of the present invention will be described with reference to the above configuration.
Fig. 6 is a diagram showing a process of aligning a display panel of the present invention. Fig. 7 to 9 are diagrams showing a process in which the display panel is transferred.
Referring to fig. 6 to 9, the thin display panel 10 is formed in a quadrangular plate shape, which is loaded to a loading area by a robot.
The lift pins 221 of the lift pin module 220 of the present invention are in a raised state in the first vacuum chuck 210. The loaded display panel 10 is placed on the upper ends of the plurality of lift pins 221. The plurality of lift pins 221 are lowered.
In this case, the control part 600 sprays air on the first vacuum chuck through the first air supply module 230 while forming a vacuum on the first vacuum chuck 210 through a vacuum device (not shown).
For this reason, the display panel 10 is in a floating state by air supplied from the lower portion at the first vacuum chuck 210.
The control unit 600 aligns the floating display panel 10 for the first time in the first set posture by using the first alignment module 240.
Next, the visual confirmation unit 251 confirms whether or not the vacuum-sucked display panel 10 is displaced from the preset reference posture, and transmits the result to the control unit 600.
The control unit 600 may perform the second alignment of the display panel 10, and then, as the alignment roller 263 is moved forward or backward by using the linear motion device 262, the display panel 10 may be brought into the reference posture.
Next, after the display panel 10 is aligned a second time, the control part 600 may control the vacuum suction of the edge region of the display panel 10 by lowering the vacuum frame 410 using the lifting device 420.
The vacuum frame 410 may include a buffer member (not shown) for buffering an impact with an edge region of the display panel 10.
In this case, when the vacuum frame 410 presses the panel 10, the above-described buffer member such as a Shock Absorber (Shock Absorber) may be installed to safely adsorb the panel in order to prevent damage.
The shape of a vacuum line (not shown) formed to form a vacuum in the vacuum frame 410 is formed to be "0", "+", and,
And the like, so that only the areas of about 10mm or less of the four sides of the edge area of the display panel 10 can be contacted, thereby improving the Vacuum (Vacuum) suction force.
The transfer unit 400 of the present invention transfers the display panel 10 to the coating region while adsorbing the edge region of the panel.
In this case, the control unit 600 sprays air of a predetermined pressure on the first vacuum chuck 210 and the second vacuum chuck 310 by using the first air supply module 230 and the second air supply module 320.
That is, the Flexible Display (Flexible Display) panel 10 adsorbs only four sides of the edge region, and thus the panel center portion sags due to its own weight.
In this state, the panel can be moved in a floating state by injecting air from the first vacuum chuck 210 and the second vacuum chuck 220, and the sagging phenomenon of the center portion of the panel 10 can be effectively prevented.
After being transferred to the coating region, the transfer part 400 places the panel 10 on the second vacuum chuck 310. In this case, the vacuum frame 410 is in four-sided contact with the edge of the second vacuum chuck 310.
Next, the control part 600 sequentially performs Vacuum (Vacuum) suction from the center part of the second Vacuum chuck 310 to the peripheral part by using a Vacuum apparatus, thereby sucking the display panel 10.
As described above, when vacuum suction is completed, the control part automatically controls the air pressure using the second air supply module 320 under the condition that Orange Peel (Orange Peel) does not occur. Here, orange Peel (Orange Peel) means that the surface of a Flexible Display (Flexible Display) panel is in an uneven state like Orange.
Also, the control part 600 is controlled to coat ink on the display panel 10 placed on the second vacuum chuck 310 by using the coating part 500.
In this case, the control unit 600 is provided with a heating temperature for heating the heating panel 330 according to the type of ink to be coated.
Thus, the control part 600 controls the current supply amount of the current supplier so that the heating panel 330 reaches a preset heating temperature during the ink coating.
Therefore, it is possible to prevent generation of unevenness (Mura) in the film formation region of the display panel 10 and to improve the coating property.
In the present invention, a separate hole is not formed in the second vacuum chuck 310.
In the case where the holes forming the vacuum are provided on the second vacuum chuck 310, it is possible to prevent unevenness and degradation of Coating (Coating) performance at the time of thin layer Inkjet Coating (injjet Coating) due to pressure difference of the vacuum and temperature deviation caused by heating.
Under the above conditions, when the ink coating process is completed on the display panel 10, the control part 600 may pick up and unload the corresponding display panel 10 by using the transfer part 400.
According to the above structure and function, the present invention has an effect that the edge regions of the four sides of the display panel having a thickness of 300 μm or less are stably transferred by linearly supplying the vacuum.
The present invention has the effect of effectively preventing the center of the panel from sagging by supplying air to the lower portion of the panel during the transfer of the thin display panel.
Further, the present invention has an effect that after the thin display panel is transferred to the coating portion, coating unevenness can be prevented by keeping the flatness of the corresponding display panel unchanged.
The present invention is not limited to the above-described embodiments and drawings, since various substitutions, modifications and changes can be made by those skilled in the art without departing from the technical spirit of the present invention.
