Description

Technical Field

[0001] An embodiment of the present invention relates to a display panel transfer device. Background Art

[0002] With the development of information technology, the importance of display devices as a connection medium between users and information has become increasingly prominent. Correspondingly, the use of display devices such as liquid crystal display devices and organic light emitting display devices is increasing.

[0003] In the manufacturing process of display devices, various processes are performed. These processes can be performed at different positions from each other. In order to safely transfer the display panel being manufactured to other positions without being physically and chemically affected, generally, after fixing the display panel to a movable carrier, the display panel is transferred by the carrier. At this time, in order to precisely move the display panel, a jig or a vacuum pump for preventing the display panel from falling off can be provided on the carrier.

[0004] The above description is only for helping to understand the background art of the technical idea of the present invention, and thus should not be construed as corresponding to the prior art known to those skilled in the technical field to which the present invention belongs. Summary of the Invention

[0005] The problem to be solved by the present invention is to provide a display panel transfer device that can transfer the display panel precisely without damage.

[0006] However, the problems of the present invention are not limited to the problems mentioned above, and those skilled in the art should be able to clearly understand other technical problems not mentioned from the following description.

[0007] The display panel transfer device according to an embodiment for solving the problem may include: a frame; a carrier disposed on the frame so as to be movable in a first direction and in a direction opposite to the first direction; a suction plate disposed on the carrier and for supporting the display panel; a first manifold including a plurality of first holes and disposed on the frame so as to be movable in a second direction intersecting the first direction and in a direction opposite to the second direction; and a second manifold including a plurality of second holes and disposed on the suction plate in a manner opposite to the first manifold. The first manifold can be driven in one of a docking mode and a standby mode. The docking mode is a mode in which the first manifold contacts the second manifold in such a way that the plurality of first holes are connected to the plurality of second holes. The standby mode is a mode in which the first manifold is separated from the second manifold in such a way that the plurality of first holes are separated from the plurality of second holes.

[0008] In one embodiment, the suction plate may include: a plurality of suction holes connected to the plurality of second holes; and a suction channel for connecting the plurality of suction holes to each other.

[0009] In one embodiment, an air suction component may be further included. When the first manifold is driven in the docking mode, the air suction component is connected to the plurality of first holes and the plurality of second holes and sucks the air between the display panel and the suction plate.

[0010] In one embodiment, the first manifold may further include a plurality of first air injection holes, and the second manifold may further include a plurality of second air injection holes. When the first manifold is driven in the docking mode, the plurality of first air injection holes and the plurality of second air injection holes are respectively connected.

[0011] In one embodiment, the number of the plurality of first holes may be the same as the number of the first air injection holes, and the number of the plurality of second holes may be the same as the number of the second air injection holes.

[0012] In one embodiment, at least one of the first manifold and the second manifold may further include a shock absorption component. The shock absorption component surrounds each of the plurality of first air injection holes or the plurality of second air injection holes on the opposite surfaces of the first manifold and the second manifold. When the first manifold is driven in the docking mode, the shock absorption component seals between one of the plurality of first air injection holes connected to each other and one of the plurality of second air injection holes connected to each other.

[0013] In one embodiment, an air injection component may be further included. When the first manifold is driven in the docking mode, the air injection component is connected to one of the plurality of first air injection holes connected to each other and one of the plurality of second air injection holes connected to each other and injects air into the interior of the second manifold.

[0014] In one embodiment, the second manifold may further include: a valve member capable of moving between a first position blocking the flow of air to one of the plurality of second holes and a second position allowing the flow of air to one of the plurality of second holes; an elastic member disposed between the inner surface of the second manifold and the valve member and configured to provide an elastic force to the valve member; and a tube having one end connected to one of the plurality of second air injection holes and the other end connected to the free space between the second manifold and the valve member.

[0015] In one embodiment, at least one of the first manifold and the second manifold may further include a shock absorption member surrounding each of the plurality of first holes or the plurality of second holes on the opposite surfaces of the first manifold and the second manifold. When the first manifold is driven in a docking mode, the shock absorption member seals between one of the plurality of first holes connected to each other and one of the plurality of second holes.

[0016] In one embodiment, a driving member may be further included, the driving member being disposed on the first manifold and configured to provide a driving force for moving the first manifold in a second direction and a direction opposite to the second direction to the first manifold.

[0017] The solution to the problem of the present invention is not limited to the above solutions. Those with ordinary knowledge in the technical field to which the present invention pertains should clearly understand the solutions not mentioned based on this application document and the drawings.

[0018] According to the display panel transfer device of the above embodiment, even without electricity, the display panel can be stably transferred in a state of vacuum adsorbing the display panel only by using pneumatic pressure.

[0019] However, the effects of the present invention are not limited to the above effects and can be extended in various ways without departing from the spirit and scope of the present invention. Description of the Drawings

[0046] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that, in the following description, only the parts necessary for understanding the operation of the present invention will be described, and other parts will be omitted so as not to obscure the gist of the present invention. In addition, the present invention is not limited to the embodiments described herein, and may be embodied in other forms. However, the embodiments described herein are provided to describe in detail to such an extent that those of ordinary skill in the technical field to which the present invention pertains can easily implement the technical idea of the present invention.

[0047] Throughout the application document, when referring to a part being "connected" to another part, this includes not only the case of "direct connection", but also the case of "indirect connection" where other structural elements are provided in between. The terms used herein are for describing specific embodiments and are not used to limit the present invention. For example, with respect to a singular form of expression, unless clearly indicated otherwise in the context, the singular form of expression includes the plural form of expression. In addition, when referring to a part "including" a certain structural element, unless there is a particularly contrary record, this means that other structural elements are not excluded, but other structural elements can be further included. "At least one of X, Y, and Z" and "at least one selected from X, Y, and Z" can be interpreted as only X, only Y, only Z, or a combination of two or more of X, Y, and Z (for example, XYZ, XY, YZ, XZ). Herein, "and / or" includes all combinations of one or more of the corresponding structures.

[0048] Herein, terms such as first, second, etc. are used to distinguish such structural elements from other structural elements. Therefore, within the scope not departing from the content disclosed herein, the first structural element may refer to the second structural element.

[0049] Spatially relative terms, such as "lower", "upper", etc., may be used for illustrative purposes to describe the relationship between one element or feature and other element(s) or feature(s) as shown in the figures. This is intended to include different orientations during use, operation, and / or manufacturing in addition to the orientation shown in the spatially relative figures. For example, when the device shown in the figures is flipped, an element described as being "lower" than other element or feature may be in the direction of being "upper" than other element or feature. Thus, in one embodiment, the term "lower" may include both upper and lower directions. Moreover, the device may be oriented in other directions (e.g., in a direction rotated 90 degrees or other directions), and thus the spatially relative terms used herein are to be interpreted according to such other directions.

[0050] Various embodiments are described with reference to the figures illustrating ideal embodiments. Thus, it can be expected that their shapes may vary according to the allowable errors and / or manufacturing techniques. Therefore, the embodiments disclosed herein should not be construed as being limited to the specific shapes shown in the figures, but should be construed as including, for example, variations in shape resulting from manufacturing. As such, the shapes shown in the figures may not illustrate the actual shape of the device area, and the present embodiments are not limited thereto.

[0051] Figure 1 is a perspective view showing an embodiment of a display panel transfer device.

[0052] Referring to Figure 1 , a display panel transfer device 10 according to an embodiment of the present invention may include a frame FR, a carrier CR, a suction plate AP, a first manifold MF1, a second manifold MF2, and a driving member DRM.

[0053] The frame FR is a structural element forming the basic skeleton of the display panel transfer device 10 and may perform a function of stably supporting other structural elements. The frame FR may extend in a first direction DR1 and may provide a space in which the carrier CR can slide on the frame FR in the first direction DR1 and in a direction opposite to the first direction DR1. In an embodiment, an LM (linear motion) guide (not shown) may be provided on the frame FR, and the carrier CR may slide on the frame FR in the direction in which the LM guide extends.

[0054] The carrier CR may be arranged on the frame FR so as to be movable in the first direction DR1 and in a direction opposite to the first direction DR1. As described above, the carrier CR may slide on a movement assisting mechanism such as an LM guide provided on the frame FR, and as a result of such sliding, the suction plate AP arranged on the carrier CR may also move together with the carrier CR.

[0055] The adsorption plate AP can be arranged on the carrier CR and support the display panel DP. The adsorption plate AP can be fixed to the carrier CR in a manner that it does not move on the carrier CR. Thus, when the carrier CR moves, the adsorption plate AP can also move together with the carrier CR. For the specific structure of the adsorption plate AP, it will be described in detail below with reference to Figure 2 as follows.

[0056] The first manifold MF1 may include a plurality of first holes H1 and may be arranged on the frame FR in a manner that it can move along a second direction DR2 intersecting the first direction DR1 and in a direction opposite to the second direction DR2. In an embodiment, the first manifold MF1 may be arranged at a height overlapping the adsorption plate AP in the horizontal direction. Here, the "horizontal direction" refers to the direction extended by the plane formed by the first direction DR1 and the second direction DR2.

[0057] The second manifold MF2 may include a plurality of second holes H2 and may be arranged on the adsorption plate AP in a manner opposite to the first manifold MF1. In an embodiment, the second manifold MF2 may be arranged at a height overlapping the first manifold MF1 in the horizontal direction. More specifically, the plurality of second holes H2 may be arranged at positions overlapping the plurality of first holes H1 one by one respectively.

[0058] In an embodiment, the first manifold MF1 can be driven in one of a docking mode and a standby mode. The docking mode is a mode in which the first manifold MF1 contacts the second manifold MF2 in a manner that the plurality of first holes H1 are connected to the plurality of second holes H2, and the standby mode is a mode in which the first manifold MF1 is separated from the second manifold MF2 in a manner that the plurality of first holes H1 are separated from the plurality of second holes H2. For the appearance of the first manifold MF1 driven in the docking mode or the standby mode, it will be described in detail below with reference to Figures 10 to 13 as follows.

[0059] The driving member DRM may be arranged on the first manifold MF1 and may provide a driving force for moving the first manifold MF1 along the second direction DR2 and in a direction opposite to the second direction DR2 to the first manifold MF1.

[0060] Next, with reference to Figure 2 the adsorption plate AP will be described in more detail.

[0061] Figure 2 is a top view showing a partial embodiment of the display panel transfer device shown in Figure 1 and Figure 3 is a cross-sectional view of an embodiment taken along I-I' of Figure 2 .

[0062] With reference to Figure 2, the adsorption plate AP may include a plurality of adsorption holes AH and a plurality of adsorption channels AT.

[0063] The plurality of adsorption holes AH may be connected to the plurality of second holes H2 through the plurality of adsorption channels AT (the binding relationship between the plurality of second holes H2 and the plurality of adsorption channels AT will be described later with reference to Figure 8 .

[0064] In an embodiment, the plurality of adsorption holes AH may include a plurality of first adsorption holes AH1 adjacent to the center of the adsorption plate AP and a plurality of second adsorption holes AH2 farther from the center of the adsorption plate AP than the plurality of first adsorption holes AH1, but the embodiment is not limited thereto. For example, the plurality of adsorption holes AH may further include a plurality of third adsorption holes AH3 farther from the center of the adsorption plate AP than the plurality of second adsorption holes AH2 and a plurality of fourth adsorption holes AH4 farther from the center of the adsorption plate AP than the plurality of third adsorption holes AH3. In this case, the first to fourth adsorption holes AH1 to AH4 are sequentially arranged in the radial direction with respect to the center of the adsorption plate AP.

[0065] The plurality of adsorption channels AT may connect the plurality of adsorption holes AH to each other. In an embodiment, the plurality of adsorption channels AT may include a first adsorption channel AT1 that connects the plurality of first adsorption holes AH1 to each other and a second adsorption channel AT2 that connects the plurality of second adsorption holes AH2 to each other, but the embodiment is not limited thereto. For example, as shown in the figure, the plurality of adsorption channels AT may further include a third adsorption channel AT3 that connects the plurality of third adsorption holes AH3 to each other and a fourth adsorption channel AT4 that connects the plurality of fourth adsorption holes AH4 to each other. In this case, the second adsorption channel AT2 may surround the first adsorption channel AT1, the third adsorption channel AT3 may surround the second adsorption channel AT2, and the fourth adsorption channel AT4 may surround the third adsorption channel AT3.

[0066] Referring to Figure 1 and Figure 2 simultaneously, the first adsorption channel AT1 may be connected to a certain second hole H2, and the second adsorption channel AT2 may be connected to another second hole H2. Similarly, the third adsorption channel AT3 may also be connected to yet another second hole H2, and the fourth adsorption channel AT4 may also be connected to a certain second hole H2 among the second holes H2 that is not connected to the first to third adsorption channels AT1 to AT3. The binding relationship between such second holes H2 and the adsorption channels AT will be described in more detail below with reference to Figure 8 .

[0067] In addition, the first to fourth adsorption channels AT1 to AT4 may not overlap with each other with respect to the vertical direction. Here, the "vertical direction" refers to the third direction DR3, which is the thickness direction of the carrier CR, the adsorption plate AP, and the display panel DP. In an embodiment, at least one of the first to fourth adsorption channels AT1 to AT4 may have an open-loop shape. For example, as Figure 2 shown, the first adsorption channel AT1 may have a closed-loop shape, and the remaining second to fourth adsorption channels AT2 to AT4 other than the first adsorption channel AT1 may have an open-loop shape and do not overlap with each other in the vertical direction.

[0068] In addition, a plurality of adsorption holes AH may penetrate the adsorption plate AP in a third direction DR3 (i.e., the vertical direction) that intersects the first direction DR1 and the second direction DR2.

[0069] Figure 3 Only the fourth adsorption hole AH4 and the fourth adsorption channel AT4 among the first to fourth adsorption holes AH1 to AH4 and the first to fourth adsorption channels AT1 to AT4 are illustrated, but in the case of the first to third adsorption holes AH1 to AH3 and the first to third adsorption channels AT1 to AT3, they may also be configured in the same manner as the fourth adsorption hole AH4 and the fourth adsorption channel AT4, so repeated descriptions are omitted.

[0070] Refer to Figure 3 , the fourth adsorption hole AH4 may penetrate the adsorption plate AP along the third direction DR3. The fourth adsorption holes AH4 may be connected to each other through the fourth adsorption channel AT4.

[0071] Refer to Figure 2 and Figure 3 simultaneously, at least one vacuum chamber VC may be provided on a surface of the adsorption plate AP that does not contact the display panel DP. Although five vacuum chambers VC extending along the second direction DR2 are shown provided on one surface of the adsorption plate AP in Figure 2 , the embodiment is not limited thereto. For example, the vacuum chamber VC may also extend along the first direction DR1, and its number and shape may be freely selected on the plane formed by the first direction DR1 and the second direction DR2. In addition, four vacuum chambers VC may be provided on the adsorption plate AP in the same number as the first to fourth adsorption channels AT1 to AT4. In this case, each vacuum chamber VC may overlap with the first to fourth adsorption channels AT1 to AT4 in the vertical direction respectively.

[0072] The internal space of the vacuum chamber VC can be maintained in a vacuum, so it can play a role in maintaining a vacuum state in the space between the display panel DP and the adsorption plate AP. In this regard, since this is related to the case where the first manifold MF1 is driven in a docking mode, it will be described below with reference toFigures 10 to 13 For a more specific description.

[0073] Next, with reference to Figures 4 to 9 the structures of the first manifold MF1 and the second manifold MF2 and their coupling relationship will be described in detail.

[0074] Figure 4 is a front view showing the appearance of the first manifold when viewed from the front. Figure 5 is showing along Figure 4 a cross-sectional view of an embodiment taken along the II-II' line. Figure 6 is showing along Figure 4 a cross-sectional view of an embodiment taken along the III-III' line.

[0075] With reference to Figures 4 to 6 , the first manifold MF1 may include a plurality of first holes H1 and a plurality of first air injection holes AIH1 (refer to Figure 10 ).

[0076] The plurality of first holes H1 may include a 1_a sub-hole H1_a, a 1_b sub-hole H1_b, a 1_c sub-hole H1_c, and a 1_d sub-hole H1_d. The 1_a to 1_d sub-holes H1_a to H1_d may be arranged along a first direction DR1.

[0077] When the first manifold MF1 is driven in a docking mode, each of the plurality of first holes H1 may be connected to a plurality of second holes H2, respectively.

[0078] The plurality of first air injection holes AIH1 may be spaced apart from the plurality of first holes H1 in a third direction DR3, and may be arranged side by side along the first direction DR1 in the same manner as the first holes H1.

[0079] In an embodiment, the number of the plurality of first holes H1 and the number of the plurality of first air injection holes AIH1 may be the same. Although it is described in the figure that four first holes H1 and first air injection holes AIH1 are formed respectively, the embodiment is not limited thereto. The number of the plurality of first holes H1 and the number of the plurality of first air injection holes AIH1 may be the same as the number of the plurality of second holes H2 formed on the second manifold MF2 and the number of the plurality of adsorption channels AT formed on the adsorption plate AP.

[0080] When the first manifold MF1 is driven in a docking mode, each of the plurality of first air injection holes AIH1 may be connected to a plurality of second air injection holes AIH2 (refer to Figure 10 ) respectively.

[0081] Figure 5 While showing an embodiment of the first manifold MF1 cut along Figure 4 the II-II', the air suction member VP connected to the plurality of first holes H1 is also illustrated.

[0082] Refer to Figure 5 Figure 5 , an air suction member VP may be connected to a plurality of first holes H1. In an embodiment, the air suction member VP may include first to fourth air suction members VP1 to VP4 respectively connected to the first to fourth sub-holes H1_a to H1_d, but the embodiment is not limited thereto. For example, the air suction member VP may also be configured by one air suction member VP and integrally connected to the first to fourth sub-holes H1_a to H1_d.

[0083] The first air suction member VP1 may be connected to the outlet H1_ao side of the first sub-hole H1_a. The second air suction member VP2 may be connected to the outlet H1_bo side of the second sub-hole H1_b. The third air suction member VP3 may be connected to the outlet H1_co side of the third sub-hole H1_c. The fourth air suction member VP4 may be connected to the outlet H1_do side of the fourth sub-hole H1_d.

[0084] Figure 6 represents an embodiment of the first manifold MF1 cut along the line III-III' of Figure 4 while also showing the air injection member AC connected to the first air injection hole AIH1.

[0085] Refer to Figure 6 Figure 6 , the first manifold MF1 may include a first air injection hole AIH1. An air injection member AC may be connected to the first air injection hole AIH1. The first air injection hole AIH1 may include one inlet AIH1_i and a plurality of outlets AIH1_o connected to the inlet AIH1_i, but the embodiment is not limited thereto. For example, the inlet AIH1_i of the first air injection hole AIH1 may also be configured as a plurality and respectively connected to the plurality of outlets AIH1_o. However, for the convenience of description, the following description will be centered on the case where the inlet AIH1_i of the first air injection hole AIH1 is one. Similarly, in the figure, one air injection member AC connected to one inlet AIH1_i of the first air injection hole AIH1 is shown, but the embodiment is not limited thereto. For example, similar to the air suction member VP including the first to fourth air suction members VP1 to VP4 respectively connected to the first to fourth sub-holes H1_a to H1_d, the air injection member AC may also be configured in the same number as the number of outlets AIH1_o of the first air injection hole AIH1.

[0086] The number of multiple outlets AIH1_o of the first air injection hole AIH1 may be the same as the number of the first holes H1. When the first manifold MF1 is driven in the docking mode, each of the multiple outlets AIH1_o of the first air injection hole AIH1 may be connected to the second air injection hole AIH2 of its corresponding second manifold MF2.

[0087] Figure 7 is a front view showing the appearance of the second manifold. Figure 8 is showing along Figure 7 a cross-sectional view of an embodiment taken along line IV-IV'. Figure 9 is showing along Figure 7 a cross-sectional view of an embodiment taken along line V-V'.

[0088] Referring to Figures 7 to 9 , the second manifold MF2 may include a plurality of second holes H2 and a plurality of second air injection holes AIH2.

[0089] The plurality of second holes H2 may include a 2_a sub-hole H2_a, a 2_b sub-hole H2_b, a 2_c sub-hole H2_c, and a 2_d sub-hole H2_d. The 2_a to 2_d sub-holes H2_a~H2_d may be arranged along the first direction DR1.

[0090] When the first manifold MF1 is driven in the docking mode, each of the plurality of second holes H2 may be respectively connected to the plurality of first holes H1.

[0091] The plurality of second air injection holes AIH2 may be spaced from the plurality of second holes H2 in the third direction DR3, and may be arranged side by side along the first direction DR1 in the same manner as the second holes H2.

[0092] In an embodiment, the number of the plurality of second holes H2 may be the same as the number of the plurality of second air injection holes AIH2. Although it is depicted in the figure that there are four second holes H2 and second air injection holes AIH2 each, the embodiment is not limited thereto. The number of the plurality of second holes H2 and the number of the plurality of second air injection holes AIH2 may be the same as the number of the plurality of first holes H1 formed on the first manifold MF1 and the number of the plurality of adsorption channels AT formed on the adsorption plate AP.

[0093] When the first manifold MF1 is driven in the docking mode, each of the plurality of second air injection holes AIH2 may be respectively connected to the plurality of first air injection holes AIH1.

[0094] Figure 8 Showing along Figure 7 a cross-section of an embodiment of the second manifold MF2 cut along line IV-IV' while also showing the first to fourth adsorption channels AT1~AT4 connected to the plurality of second holes H2.

[0095] Reference Figure 8 , a plurality of adsorption channels AT may be connected to a plurality of second holes H2. In an embodiment, the inlet H2_ai of the 2_a sub-hole H2_a may be connected to the first adsorption channel AT1. The inlet H2_bi of the 2_b sub-hole H2_b may be connected to the second adsorption channel AT2. The inlet H2_ci of the 2_c sub-hole H2_c may be connected to the third adsorption channel AT3. The inlet H2_di of the 2_d sub-hole H2_d may be connected to the fourth adsorption channel AT4. At this time, the number of the plurality of second holes H2 may be the same as the number of the plurality of adsorption channels AT.

[0096] On the side of the second manifold MF2 opposite to the first manifold MF1, a shock absorption member SAP surrounding each of the plurality of second holes H2 may be further included. The shock absorption member SAP is a structural element that contracts when an external force is applied and returns to its original shape when the external force is removed, and it may be made of a material having a specified elasticity. For example, the shock absorption member SAP may include substances such as silicone, natural rubber, and elastic rubber.

[0097] Reference Figure 9 , the second manifold MF2 may include a plurality of second air injection holes AIH2. The number of the second air injection holes AIH2 may be the same as the number of the second holes H2. When the first manifold MF1 is driven in the docking mode, each of the second air injection holes AIH2 may be respectively connected to the corresponding first air injection hole AIH1 of the first manifold MF1.

[0098] On the side of the second manifold MF2 opposite to the first manifold MF1, a shock absorption member SAP surrounding each of the plurality of second air injection holes AIH2 may be further included. Thus, the shock absorption member SAP may surround the plurality of second holes H2 and the plurality of second air injection holes AIH2, but the embodiment is not limited thereto. For example, the shock absorption member SAP may be further formed on the first manifold MF1. In another embodiment, the first manifold MF1 may also further include a shock absorption member SAP surrounding the plurality of first holes H1 and the plurality of first air injection holes AIH1.

[0099] Figure 10 is a cross-sectional view of an embodiment along the A-A' line along Figure 4 and along the B-B' Figure 7 when the first manifold and the second manifold are in contact with each other.

[0100] Although in Figure 10Only the 1_dth sub-holes H1_d and 2_dth sub-holes H2_d among the 1_ath to 1_dth sub-holes H1_a to H1_d and the 2_ath to 2_dth sub-holes H2_a to H2_d are illustrated, but in the case of the 1_ath to 1_cth sub-holes H1_a to H1_c and the 2_ath to 2_cth sub-holes H2_a to H2_c, they can also be constructed in the same way as the 1_dth sub-holes H1_d and 2_dth sub-holes H2_d, so the repeated description is omitted.

[0101] Refer to Figure 10 , when the first manifold MF1 is driven in the docking mode, the first manifold MF1 can approach the second manifold MF2 side and dock with the second manifold MF2. Thus, in order to make the first manifold MF1 enter the docking mode, the carrier CR can temporarily interrupt the movement along the first direction DR1 and the direction opposite to the first direction DR1. In other words, during the movement of the carrier CR along the first direction DR1 and the direction opposite to the first direction DR1 for transporting the display panel DP, in order to adsorb the display panel DP to the adsorption plate AP, the carrier CR can be paused at a position where the first manifold MF1 and the second manifold MF2 overlap in the second direction DR2.

[0102] Thus, in a state where the movement of the carrier CR is aborted, the first manifold MF1 enters the docking mode and moves towards the second manifold MF2, and finally docks with the second manifold MF2.

[0103] Thus, when the first manifold MF1 and the second manifold MF2 are docked, the 1_dth sub-hole H1_d and the second sub-hole H2_d can be connected to each other. In addition, although not illustrated in the figure, when the first manifold MF1 and the second manifold MF2 are docked, the 1_ath sub-hole H1_a can be connected to the 2_ath sub-hole H2_a, the 1_bth sub-hole H1_b can be connected to the 2_bth sub-hole H2_b, and the 1_cth sub-hole H1_c can be connected to the 2_cth sub-hole H2_c.

[0104] In addition, when the first manifold MF1 and the second manifold MF2 are docked, the first air injection hole AIH1 and the second air injection hole AIH2 can also be connected to each other.

[0105] In the embodiment, on the surface where the inflow port H1_di of the 1_dth sub-hole H1_d and the outflow port H2_do of the 2_dth sub-hole H2_d meet, the shock absorption member SAP contracts between the first and second manifolds MF1, MF2, so that the 1_dth sub-hole H1_d and the 2_dth sub-hole H2_d can be sealed. In this case, the air flowing from the 2_dth sub-hole H2_d to the 1_dth sub-hole H1_d can not leak from between the first and second manifolds MF1, MF2.

[0106] Similarly, on the surface where the outlet AIH1_o of the first air injection hole AIH1 and the inlet AIH2_i of the second air injection hole AIH2 meet each other, the shock absorption part SAP contracts between the first and second manifolds MF1 and MF2, so that the space between the first air injection hole AIH1 and the second air injection hole AIH2 can be sealed. In this case, the air flowing from the first air injection hole AIH1 to the second air injection hole AIH2 can be prevented from leaking between the first and second manifolds MF1 and MF2.

[0107] As described later, the first manifold MF1 is driven in the docking mode to convert the space between the display panel DP and the adsorption plate AP into a vacuum state so that the display panel DP is adsorbed to the adsorption plate AP, or to release the vacuum state so that the display panel DP is separated from the adsorption plate AP. From this point of view, the driving of the first manifold MF1 in the docking mode is a repetitive operation rather than a one-time operation. In other words, during the process of the first manifold MF1 approaching the second manifold MF2 side and contacting the second manifold MF2, a specified shock will be generated between the first manifold MF1 and the second manifold MF2. If such shocks continuously accumulate, fatigue failure may also occur. The shock absorption part SAP can absorb the inevitable shock between the first manifold MF1 and the second manifold MF2, thereby improving the overall durability and reliability of the display panel transfer device 10, and further preventing fatigue failure.

[0108] Next, with reference to Figures 11 to 13 working examples of the standby mode and the docking mode of the display panel transfer device 10 will be described.

[0109] Figure 11 It is a schematic diagram showing an embodiment of the second manifold when the first manifold is in the standby mode.

[0110] First, with reference to Figure 11 the internal structure of the second manifold MF2 will be further described. As Figure 11 shown, the second manifold MF2 may further include a valve member VM, an elastic member EM, and a tube TB.

[0111] The valve member VM can move between a first position P1 that blocks the flow of air to one of the plurality of second holes H2 and a second position (refer to Figure 12 and Figure 13 P2) that allows the flow of air to one of the plurality of second holes H2.

[0112] The elastic member EM can be disposed between the inner surface of the second manifold MF2 and the valve member VM, and provide a prescribed elastic force to the valve member VM. In an embodiment, the elastic member EM can be a compression spring. One end of the elastic member EM can be in a state fixed to the inner surface of the second manifold MF2, and the other end of the elastic member EM can apply a force to push the valve member VM in the third direction DR3 to the valve member VM. In other words, the valve member VM can move to the first position P1 by the elastic force of the elastic member EM and maintain the first position P1.

[0113] One end of the tube TB can be connected to one of the plurality of second air injection holes AIH2, and the other end can be connected to the free space ES between the second manifold MF2 and the valve member VM.

[0114] As described above, Figure 11 It shows the appearance of the first manifold MF1 being driven in the standby mode, at which time the air suction member VP does not operate. In addition, Figure 11 It shows the state in which the display panel DP is adsorbed on the adsorption plate AP by executing the docking mode to be described below with reference to Figure 12 As such, in the state where the carrier CR supports the adsorption plate AP and the adsorption plate AP adsorbs the display panel DP, the carrier CR can move in the first direction DR1 and the direction opposite to the first direction DR1. Thereby, the carrier CR can transfer the display panel DP in the state of fixing the display panel DP to the adsorption plate AP in the first direction DR1 and the direction opposite to the first direction DR1.

[0115] Hereinafter, for convenience of explanation, with reference to the center of the valve member VM as a reference, a part of the second manifold MF2 adjacent to the first manifold MF1 side is referred to as the front end portion FP, and another part of the second manifold MF2 adjacent to the adsorption plate AP is referred to as the rear end portion TP.

[0116] As Figure 11As shown, during the movement of the carrier CR in the standby mode, the valve member VM can assume a posture of maintaining the first position P1 by the elastic force of the elastic member EM. As described above, since a vacuum state exists between the adsorption plate AP and the display panel DP, the rear end portion TP of the second sub-hole H2_d can also be under vacuum conditions. On the contrary, the front end portion FP of the second sub-hole H2_d is connected to the air suction member VP, so it can be under vacuum conditions or in a state with a pressure slightly higher than the vacuum. In this case, there may be no air flow inside the second sub-hole H2_d, or air may be guided to flow from the first sub-hole H1_d to the second sub-hole H2_d. Under these conditions, the valve member VM can move to the first position P1 by the elastic force that presses the valve member VM by the elastic member EM and can maintain this posture. In other words, since the pressure of the air guided from the first sub-hole H1_d to the second sub-hole H2_d is less than the elastic force that presses the valve member VM by the elastic member EM, the valve member VM does not move in the direction opposite to the third direction DR3 but is fixed at the first position P1, thereby blocking the air flow in the direction from the first sub-hole H1_d to the second sub-hole H2_d.

[0117] According to this structure, even without electricity, only by using air pressure, the vacuum state between the display panel DP and the adsorption plate AP can be maintained. Thus, the display panel DP can be stably adsorbed on the adsorption plate AP and the carrier CR can be transferred, thereby transferring the display panel DP.

[0118] Figure 12 It is a schematic diagram showing an operating example of the second manifold when the first manifold is driven in the docking mode.

[0119] Refer to Figure 12 , as the first manifold MF1 is driven in the docking mode, the first manifold MF1 and the second manifold MF2 can come into contact with each other, and in this state, the air suction member VP can operate. Thus, when the air suction member VP operates in the state where the first manifold MF1 is driven in the docking mode, the display panel DP can be adsorbed onto the adsorption plate AP. The adsorption of the display panel DP onto the adsorption plate AP can be achieved by converting the space between the display panel DP and the adsorption plate AP into a vacuum state by using the air suction member VP, so it is called the "vacuum mode" in the figure.

[0120] The appearance of the first manifold MF1 and the second manifold MF2 coming into contact with each other is cited Figure 10 , in Figure 12 , for the convenience of explanation, the illustration of the first manifold MF1 is omitted.

[0121] When the air suction component VP operates, an air flow is generated from the inlet H2_di of the second d-sub hole H2_d toward the outlet H2_do side of the second d-sub hole H2_d. A more specific description thereof is as follows.

[0122] When the air suction component VP starts to operate, the pressure at the front end portion FP of the second d-sub hole H2_d instantaneously becomes lower than the pressure at the rear end portion TP of the second d-sub hole H2_d. As a result, an air flow is generated through the minute gap between the valve component VM and the second manifold MF2. Since the air suction component VP continues to operate in this state, the amount of air flowing from the inlet H2_di of the second d-sub hole H2_d toward the outlet H2_do side of the second d-sub hole H2_d gradually increases. After that, at a certain point in time, the air pressure of the air flowing from the inlet H2_di of the second d-sub hole H2_d toward the outlet H2_do side of the second d-sub hole H2_d may be greater than the elastic force with which the elastic component EM presses the valve component VM in the third direction DR3. Thus, when the air pressure of the air flowing from the inlet H2_di of the second d-sub hole H2_d toward the outlet H2_do side of the second d-sub hole H2_d is greater than the elastic force of the elastic component EM, the valve component VM can move to the second position P2.

[0123] Thus, when the air suction component VP continues to operate in the state where the valve component VM has moved to the second position P2, the air existing between the display panel DP and the adsorption plate AP can be continuously suctioned through the fourth adsorption hole ( Figure 2 AH4 in), and the air suctioned through the fourth adsorption hole AH4 can be suctioned into the air suction component VP in sequence via the fourth adsorption passage ( Figure 8 AT4 in), the second d-sub hole H2_d, and the first d-sub hole H1_d.

[0124] Although not shown in the figure, similarly to the content described above, when the air suction component VP operates, an air flow is generated from the inlet ( Figure 8 H2_a in) of the second a-sub hole ( Figure 8 H2_ai in) toward the outlet ( Figure 8 H2_ao in) side of the second a-sub hole H2_a. Based on the same principle as the principle described above, when the air suction component VP operates, air is first suctioned through the first adsorption hole ( Figure 2 AH1 in), and the air suctioned through the first adsorption hole AH1 can be suctioned into the air suction component VP in sequence via the first adsorption passage ( Figure 8 AT1 in), the second a-sub hole H2_a, and the first a-sub hole H1_a.

[0125] In addition, when the air suction component VP operates, an air flow is generated from the second b-sub hole (Figure 8 The inlet of H2_b) in Figure 8 H2_bi) in flows into the second sub-hole Figure 8 The outlet of H2_b) in Figure 8 Air flow on the side of H2_bo). According to the same principle as the one described above, when the air suction member VP operates, air is sucked in through the second adsorption hole Figure 2 AH2) in. The air sucked in through the second adsorption hole AH2 can successively pass through the second adsorption channel Figure 8 AT2) in, the second sub-hole H2_b, and the first sub-hole H1_b and is sucked into the air suction member VP.

[0126] In addition, when the air suction member VP operates, air flow is generated from the inlet of the second sub-hole Figure 8 H2_c) in Figure 8 H2_ci) in flows into the second sub-hole Figure 8 The outlet of H2_c) in Figure 8 H2_co) side in. According to the same principle as the one described above, when the air suction member VP operates, air is sucked in through the third adsorption hole Figure 2 AH3) in. The air sucked in through the third adsorption hole AH3 can successively pass through the third adsorption channel Figure 8 AT3) in, the second sub-hole H2_c, and the first sub-hole H1_c and is sucked into the air suction member VP.

[0127] In this way, when the air suction member VP operates in the state where the first manifold MF1 and the second manifold MF2 are docked, the valve member VM can move to the second position P2 to open the flow paths of the plurality of second holes H2. As a result, the air existing between the first to fourth adsorption holes AH1 to AH4 and the display panel DP can be sucked to the air suction member VP side. As a result, the space between the display panel DP and the adsorption plate AP can be induced to a vacuum condition, and thus the display panel DP can be adsorbed to the adsorption plate AP.

[0128] In addition, as described above with reference to Figure 5 The air suction member VP may include first to fourth air suction members VP1 to VP4, and at least one of the first to fourth air suction members VP1 to VP4 can also be independently operated. This can be a structure made to selectively suck the air around the first to fourth adsorption holes AH1 to AH4 required for adsorbing the display panel DP in consideration of the size of the display panel DP.

[0129] For example, when the display panel DP is a large panel sized to overlap with all of the first to fourth adsorption holes AH1 to AH4, the space between the display panel DP and the adsorption plate AP corresponding to the area occupied by the first to fourth adsorption holes AH1 to AH4 can be converted to a vacuum state by operating all of the first to fourth air suction components VP1 to VP4. Alternatively, when the display panel DP is a small panel sized to overlap only with the first adsorption hole AH1 and not with the second to fourth adsorption holes AH2 to AH4, only the first air suction component VP1 can be operated so that only the space between the display panel DP and the adsorption plate AP corresponding to the area occupied by the first adsorption hole AH1 is converted to a vacuum state. When the first to fourth air suction components VP1 to VP4 are independently operated in consideration of the size of the display panel DP in this way, unnecessary driving can be omitted, and thus power consumption can be saved.

[0130] After the display panel DP is adsorbed to the adsorption plate AP, the driving of the air suction component VP can be interrupted. When the driving of the air suction component VP is interrupted, the space between the display panel DP and the adsorption plate AP can be in a state induced to a vacuum state. In addition, the air suction component VP side can also maintain a vacuum state for a specified time after the driving is interrupted. Thereby, within the specified time after the driving of the air suction component VP is interrupted, the space between the display panel DP and the adsorption plate AP and the air suction component VP can maintain a state having substantially the same pressure. Thereby, air flow can be prevented from occurring inside the second_d sub-hole H2_d. When there is no air flow inside the second_d sub-hole H2_d in this way, the valve member VM can be restored to the first position P1 again by the elastic force applied by the elastic member EM in the third direction DR3, as Figure 11 shown.

[0131] According to this operation, even if power is not supplied separately to maintain the space between the display panel DP and the adsorption plate AP in a vacuum state, the valve member VM will move to the first position P1 and mechanically block the flow path of the second hole H2, so that the space between the display panel DP and the adsorption plate AP can be continuously maintained in a vacuum state, and thus the display panel DP can be stably adsorbed on the adsorption plate AP. In this state, as described with reference to Figure 11 the carrier CR can move along the first direction DR1 and the direction opposite to the first direction DR1 to transfer the display panel DP.

[0132] Figure 13 is a schematic diagram showing another working example of the second manifold when the first manifold is driven in a docking mode.

[0133] Figure 13 is showing when performing Figure 12The figure of the "vacuum break mode" that can be executed later in the state where the display panel DP is adsorbed on the adsorption plate AP in the shown vacuum mode.

[0134] After executing Figure 12 the shown "vacuum mode", even without additional power supply, the display panel DP can be mechanically transferred in the state of being adsorbed on the adsorption plate AP. At a certain point in time later, when it is necessary to separate the display panel DP from the adsorption plate AP, the Figure 13 shown vacuum break mode can be executed.

[0135] Referring to Figure 13 , as the first manifold MF1 is driven in the docking mode, the first manifold MF1 and the second manifold MF2 can come into contact with each other, and in this state, the air injection component AC can operate. Thus, when the air injection component AC operates in the state where the first manifold MF1 is driven in the docking mode, the vacuum state can be released by injecting air into the space between the display panel DP and the adsorption plate AP.

[0136] Similar to Figure 12 , the appearance of the first manifold MF1 and the second manifold MF2 coming into contact with each other is cited in Figure 10 , and in Figure 13 , the illustration of the first manifold MF1 is omitted for convenience of explanation.

[0137] When the air injection component AC operates, an air flow is generated from the inflow port AIH2_i of the second air injection hole AIH2 toward the outflow port AIH2_o side of the second air injection hole AIH2. A more specific description of this is as follows.

[0138] When the air injection component AC starts to operate, the air injected into the second air injection hole AIH2 can move along the tube TB and flow into the empty space ES between the valve component VM at the front end FP of the second manifold MF2 and the second manifold MF2. The air flowing into the empty space ES between the valve component VM and the second manifold MF2 can apply a force to push the valve component VM in the direction opposite to the third direction DR3. From the moment when the air pressure applied to the empty space ES by the air flowing into the empty space ES is greater than the elastic force of the elastic component EM that pushes the valve component VM in the third direction DR3, the valve component VM can move in the direction opposite to the third direction DR3 (i.e., downward), and finally can move to the second position P2 where the 2_d sub-hole H2_d is opened.

[0139] In the case where the valve component VM moves to the second position P2 as described above, an air flow can be generated from the air suction component VP with a relatively high air pressure toward the fourth adsorption hole AH4 (in Figure 13Air flow in the second direction DR2). Thus, air can flow from the air suction component VP into the first_d sub-hole H1_d, and the air flowing into the first_d sub-hole H1_d can successively pass through the second_d sub-hole H2_d, the fourth adsorption channel ( Figure 8 AT4) in it and the fourth adsorption hole ( Figure 2 AH4) in it and be injected into the space between the display panel DP and the adsorption plate AP.

[0140] For such driving, the air suction component VP can standby in a state where the vacuum state is no longer maintained after executing the vacuum mode. In other words, in the vacuum breaking mode, the air suction component VP can be in a state with an internal pressure relatively higher than the vacuum state.

[0141] Although not shown in the figure, when the air injection component AC works, air flow is generated from the outlet ( Figure 8 H2_ao) of the second_a sub-hole ( Figure 8 H2_a) to the inlet H2_ai side of the second_a sub-hole H2_a. According to the same principle as described above, when the air injection component AC works, as the valve component VM moves to the second position P2, air begins to flow in through the first_a sub-hole H1_a, and the air flowing into the first_a sub-hole H1_a can successively pass through the second_a sub-hole H2_a, the first adsorption channel ( Figure 8 AT1) in it and the first adsorption hole AH1 and flow into the space between the display panel DP and the adsorption plate AP.

[0142] In addition, when the air injection component AC works, air flow is generated from the outlet ( Figure 8 H2_bo) of the second_b sub-hole ( Figure 8 H2_b) to the inlet H2_bi side of the second_b sub-hole H2_b. According to the same principle as described above, when the air injection component AC works, as the valve component VM moves to the second position P2, air begins to flow in through the first_b sub-hole H1_b, and the air flowing into the first_b sub-hole H1_b can successively pass through the second_b sub-hole H2_b, the second adsorption channel ( Figure 8 AT2) in it and the second adsorption hole AH2 and flow into the space between the display panel DP and the adsorption plate AP.

[0143] In addition, when the air injection component AC works, air flow is generated from the outlet ( Figure 8 H2_c) of the second_c sub-hole ( Figure 8The air flow in the H2_co) in [X] towards the inlet H2_ci side of the second sub-hole H2_c. According to the same principle as the principle described above, when the air injection component AC operates, as the valve component VM moves to the second position P2, air begins to flow in through the first sub-hole H1_c, and the air flowing into the first sub-hole H1_c can successively pass through the second sub-hole H2_c, the third adsorption channel ( Figure 8 AT3) in [X] and the third adsorption hole AH3 and flow into the space between the display panel DP and the adsorption plate AP.

[0144] In this way, when the air injection component AC operates in the state where the first manifold MF1 and the second manifold MF2 are docked, the valve component VM can move to the second position P2 to open the flow path of the second hole H2. Therefore, air can be supplied to the space between the first to fourth adsorption holes AH1 - AH4 in a vacuum state and the display panel DP. Thereby, the adsorption state between the display panel DP and the adsorption plate AP can be released.

[0145] In addition, although not shown in the figure, the air injection component AC can also correspond one-to-one with each second air injection hole AIH2 in the same way as the air suction component VP, and can also be provided with a plurality of air injection components AC in such a way as to inject air into each second air injection hole AIH2. Thereby, the air injection component AC can also operate independently so as to supply air to the area that needs to break the vacuum state among the first to fourth adsorption holes AH1 - AH4. When the plurality of air injection components AC operate independently in consideration of the size of the display panel DP in this way, unnecessary driving can be omitted, so power consumption can be saved.
