[0032] Hereinafter, embodiments will be described in more detail with reference to the accompanying drawings. The same reference numerals are used for the same components in the drawings, and redundant descriptions of the same components will be omitted.
[0033] Figure 1 is an exploded perspective view of a tray module according to an embodiment of the present disclosure.
[0034] refer to Figure 1 , the tray module 1 according to an embodiment of the present disclosure may include a tray 100 and a buffer 200 .
[0035] The pallet 100 may load, transport, and store the loading target part 220. To this end, the pallet 100 may have a damage prevention structure for the loading target part 220.
[0036] In an embodiment, the pallet 100 may include a single material of synthetic resin. In an embodiment, the pallet 100 may include polystyrene (PS). For example, the pallet 100 may include a material obtained by adding rubber to polystyrene.
[0037] However, the present disclosure is not limited thereto. For example, the tray 100 may include various materials that can be vacuum-formed. For example, the tray 100 may include various materials such as EPS, ABS, and PAP. These may be used alone or in combination with each other.
[0038] Will be referenced below Figure 2 A detailed description of the structure of the tray 100 is described below and so on.
[0039] The buffer 200 may be plural. For example, the buffer 200 may include a first buffer 210 and a second buffer 230.
[0040] The buffer 200 may be disposed above and below the loading target part 220. In an embodiment, the first buffer 210 may be disposed on the tray 100, and the second buffer 230 may be disposed on the first buffer 210.
[0041] The buffer 200 may buffer an impact applied to the loading target part 220. For example, the first buffer 210 may buffer an impact applied from an upper portion of the loading target part 220, and the second buffer 230 may buffer an impact applied from a lower portion of the loading target part 220.
[0042] However, the present disclosure is not limited thereto. For example, the tray 100 and the first buffer 210 may be provided as one body. In this case, the buffer 200 may include only the second buffer 230 provided on the loading target part 220. For another example, in addition to the first buffer 210 and the second buffer 230, the buffer 200 may further include an additional buffer.
[0043] Each of the first buffer 210 and the second buffer 230 may include the same material. In an embodiment, each of the first buffer 210 and the second buffer 230 may include a porous synthetic resin. In an embodiment, each of the first buffer 210 and the second buffer 230 may include low-density polyethylene (LDPE).
[0044] However, the present disclosure is not limited thereto. For example, the buffer 200 may include a material that can remove static electricity charged in the loading target part 220. For another example, the buffer 200 may include a material that buffers an impact applied to the loading target part 220.
[0045] In addition, the first buffer 210 and the second buffer 230 may include different materials. For example, one of the first buffer 210 and the second buffer 230 may include a material that buffers impact applied to the loading target part 220, and the other may include a material that prevents friction.
[0046] The loading target component 220 may be a component included in a display device. In an embodiment, the loading target component 220 may be a display panel. The display panel may have a thickness of about 0.3 mm or less. However, the present disclosure is not limited thereto.
[0047] For example, the display panel may not include a cover window. The cover window may include an impact-resistant material. Therefore, an impact applied to the display panel may be buffered. In other words, if the display panel does not include a cover window, the display panel may be easily damaged by the impact.
[0048] In order to prevent the display panel from being damaged during transportation of components included in the display device, the tray module 1 may have various anti-breakage structures. Figure 2 A detailed description of this is described below.
[0049] Will be referenced below Figure 2 A detailed description of the structure of the tray 100 is described below and so on.
[0050] Figure 2 It is shown that the Figure 1 A plan view of a pallet in a pallet module.
[0051] refer to Figure 2 , the tray 100 may include a support portion SU, a container portion PO, and a gap maintaining stopper ZS. Hereinafter, for convenience of explanation, the gap maintaining stopper ZS will be referred to as a stopper ZS.
[0052] The support portion SU may surround the container portion PO. For example, the support portion SU may include a plurality of side walls. For example, the support portion SU may include a first side wall, a second side wall, a third side wall, and a fourth side wall. For example, the first side wall and the third side wall may face each other in the first direction DR1. Each of the second side wall and the fourth side wall may be connected to the first side wall and the third side wall, and the second side wall and the fourth side wall may face each other in the second direction DR2.
[0053] The second direction DR2 may cross the first direction DR1. For example, the first direction DR1 and the second direction DR2 may be perpendicular to each other.
[0054] The plurality of side walls may have a predetermined height and thickness. For example, depending on the loading target component (e.g., Figure 1 Depending on the size, thickness, stacking number, etc. of the loading target part 220, the plurality of side walls may have various heights and thicknesses.
[0055] For example, when the loading target part 220 is a display panel, the plurality of side walls may have a height that may prevent the display panel from falling and a thickness that may buffer an impact applied to the display panel.
[0056] The loading target part 220 may be seated in the container part PO. In order to prevent the loading target part 220 from being separated, the container part PO may have a shape surrounded by the support part SU.
[0057] In an embodiment, the container part PO may include a seating area FA and an edge area SA.
[0058] In an embodiment, the seating area FA may include a seating surface SS on which the loading target part 220 may be seated. The seating surface SS may be parallel to a plane defined by the first direction DR1 and the second direction DR2.
[0059] As mentioned above, the buffer (e.g. Figure 1 The buffer 200 may be further disposed above and below the loading target part 220 disposed in the placement area FA. For example, the buffer 200 may be disposed on the tray 100 (eg, in the third direction DR3).
[0060] The third direction DR3 may intersect each of the first direction DR1 and the second direction DR2. For example, the first direction DR1, the second direction DR2, and the third direction DR3 may each be perpendicular to each other.
[0061] In an embodiment, the edge area SA may surround the placement area FA. The edge area SA may provide a space between the support portion SU and the loading target component 220 disposed on the placement surface SS. Therefore, even if the loaded component moves during transportation, the loading target component 220 may be prevented from being damaged due to collision with the support portion SU.
[0062] In an embodiment, the edge area SA may have a predetermined width W1. In an embodiment, the width W1 of the edge area SA defined in the container portion PO of the tray 100 may be about 8 mm or more and about 10 mm or less.
[0063] For example, if the width W1 of the edge area SA is less than about 8 mm, the loading target component 220 may be damaged. During an international standard drop test (e.g., a drop test from a height of about 76 cm), the loading target component 220 may move up to about 4 mm. In addition, during a drop test from a height of 1 m, the loading target component 220 may move up to about 7 mm. Therefore, when the width W1 of the edge area SA is about 8 mm or more, even if the loading target component 220 moves, the loading target component 220 may move within the seating area FA and the edge area SA, so that the loading target component 220 may be prevented from being damaged due to collision with the support portion SU.
[0064] On the other hand, if the width W1 of the edge area SA exceeds about 10 mm, the pallet manufacturing cost may increase. In addition, as the pallet 100 becomes larger, the loading efficiency may decrease. For example, the pallet 100 can accommodate one or more loading targets, and a plurality of pallets 100 can be loaded and transported on a pallet. Therefore, as the pallet 100 becomes larger, the number of pallets 100 that can be transported on the pallet at one time decreases, thereby reducing the loading efficiency.
[0065] Figure 2 is an example, and the structure of the tray 100 may be changed in various ways. For example, a plurality of container parts PO may be provided in the tray 100. For example, a container part PO capable of accommodating a display panel and a circuit board may be provided. In this case, since the display panel and the circuit board are accommodated separately, the possibility of damage may be reduced.
[0066] In addition, as described above, the tray 100 can be formed by vacuum forming. Therefore, the support portion SU and the container portion PO may include the same material. However, the present disclosure is not limited thereto. For example, the support portion SU and the container portion PO may be manufactured and then arranged in an assemblable form. In this case, the support portion SU and the container portion PO may include different materials.
[0067] The stopper ZS may protrude in the third direction DR3. Figure 3 and Figure 4 A detailed description of the stopper ZS is described.
[0068] Figure 3 It shows that the setting Figure 2 A plan view of the buffer on the pallet. Figure 4 It is along Figure 3 A cross-sectional view taken along line II'.
[0069] refer to Figure 3 and Figure 4In an embodiment, the loading target part 220 may be disposed on the pallet 100, and the buffer 200 may be disposed on the upper and lower portions of the loading target part 220. For example, the first buffer 210 may be disposed on the pallet 100, the loading target part 220 may be disposed on the first buffer 210, and the second buffer 230 may be disposed on the loading target part 220.
[0070] As described above, the tray 100 may include an anti-breakage structure. For example, in an embodiment, the tray 100 may include an edge area SA and a stopper ZS defined in the container portion PO.
[0071] As described above, in the embodiment, the width W1 of the edge area SA may be about 8 mm or more and about 10 mm or less. Therefore, even if the loading target part 220 moves during transportation, when the loading target part 220 moves within the seating area FA and the edge area SA, the support portion (e.g., Figure 2 The supporting part SU) is damaged.
[0072] In an embodiment, the stopper ZS may protrude from the base of the container portion PO in the third direction DR3. The stopper ZS may have a first length of protrusion length LE1. In other words, the stopper ZS may protrude from the base of the container portion PO in the third direction DR3 by a first length of protrusion length LE1.
[0073] The first buffer 210 and the second buffer 230 may have substantially the same shape. Therefore, in order to avoid overlapping descriptions, the subsequent description hereinafter will focus on the second buffer 230.
[0074] For example, in a cross-sectional view, the second buffer 230 may have a thickness LE2 of a second length. For example, the thickness LE2 of the second buffer 230 may mean a length in the third direction DR3. For example, the second length may be about 1.6 mm.
[0075] In an embodiment, the first length may be greater than the second length. For example, if the second length is about 1.6 mm, the first length may exceed about 1.6 mm. In other words, the protruding length LE1 of the stopper ZS may be greater than the thickness LE2 of the second buffer 230 .
[0076] Figure 4 is an example, and the structure of the tray 100 may be changed in various ways. For example, a plurality of stoppers ZS may be provided. On the other hand, the position and area of the placement surface SS (ie, the surface on which the loading target component 220 and the tray 100 contact) may also be changed in various ways.
[0077] In addition, the first buffer 210 and the second buffer 230 may have various shapes. Figure 4 , it is illustrated that one side of the loading target part 220 and one side of the buffer 200 are positioned in a straight line, however, the present disclosure is not limited thereto.
[0078] For example, in order to buffer the impact applied to the side of the loading target part 220, the buffer 200 may have a larger area than the loading target part 220. (For example, in a cross-sectional view, the side of the buffer 200 may be formed longer so as to overlap the edge area SA more than the side of the loading target part 220.)
[0079] The stopper ZS can prevent the loading target component 220 from moving during transportation by pressing the second buffer 230. Figure 5 A detailed description of this is described below.
[0080] Figure 5 , Figure 6 and Figure 7 It is shown that the use Figure 1 Figure 1 shows the transport method of pallet modules.
[0081] refer to Figure 5 , a loading target part 220 a may be set on the first tray 100 a ( S100 ).
[0082] As described above, in an embodiment, the loading target part 220a may be a display panel. The thickness LEP of the display panel may be about 0.3 mm or less. As the thickness LEP of the display panel decreases, the probability of damage during transportation may increase. Therefore, it may be important to buffer impact during transportation.
[0083] As the resolution of the display panel increases, the guide area may become smaller. The guide area may refer to a protrusion formed on the first tray 100a to buffer impact during transportation. As the guide area becomes smaller, the amount of buffering of impact decreases, and thus the probability of damage during transportation may increase. For example, in a plan view, if the width of the guide area is less than about 10 mm, cracks may easily occur in the display panel.
[0084] Since the tray module 1 according to the embodiment of the present disclosure includes the buffers 200a above and below the loading target part 220a, the cracking of the display panel can be prevented. For example, the first buffer 210a can be set on the first tray 100a, the loading target part 220a can be set on the first buffer 210a, and the second buffer 230a can be set on the loading target part 220a.
[0085] In addition, since the tray module 1 further includes the stopper ZS having the first length of the protrusion length LE1 and the second buffer 230a having the second length of the thickness LE2, the cracking of the display panel can be more prevented. A detailed description of this will be described below.
[0086] refer to Figure 1 , Figure 6 and Figure 7 , the tray modules 1 may be stacked into a plurality of stages ( S200 ).
[0087] The tray module 1 may include a tray 100 and a buffer 200 , and each of the tray 100 and the buffer 200 may be provided in plurality.
[0088] For example, about 14 pallets 100 may be loaded on the pallet. Therefore, the pallet may transport about 14 pallets 100 at the same time.
[0089] For example, the pallet 100 farthest from the pallet (ie, the pallet 100 positioned at the top on the pallet in the fourth direction DR4 opposite to the third direction DR3) may be a dummy pallet. The dummy pallet may prevent debris from accumulating.
[0090] For example, the tray 100 may include a first tray 100 a and a second tray 100 b .
[0091] In an embodiment, each of the first tray 100a and the second tray 100b may include a single material synthetic resin. In an embodiment, each of the first tray 100a and the second tray 100b may include polystyrene (PS). For example, each of the first tray 100a and the second tray 100b may include a material obtained by adding rubber to polystyrene.
[0092] However, the present disclosure is not limited thereto.For example, the first tray 100a and the second tray 100b may include various materials, and may be made of the same material or different materials.
[0093] For example, the buffer 200 may include a buffer 200 a and a buffer 200 b , wherein the buffer 200 a includes a first lower buffer 210 a and a second lower buffer 230 a , and the buffer 200 b includes a first upper buffer 210 b and a second upper buffer 230 b .
[0094] In an embodiment, a first lower buffer 210a may be provided on the first pallet 100a, and a first loading target part 220a may be provided on the first lower buffer 210a, a second lower buffer 230a may be provided on the first loading target part 220a, a second pallet 100b may be provided on the second lower buffer 230a, a first upper buffer 210b may be provided on the second pallet 100b, a second loading target part 220b may be provided on the first upper buffer 210b, and a second upper buffer 230b may be provided on the second loading target part 220b.
[0095] In an embodiment, each of the first lower buffer 210a, the second lower buffer 230a, the first upper buffer 210b, and the second upper buffer 230b may include a porous synthetic resin. In an embodiment, each of the first lower buffer 210a, the second lower buffer 230a, the first upper buffer 210b, and the second upper buffer 230b may include low density polyethylene (LDPE).
[0096] However, the present disclosure is not limited thereto. For example, each of the first lower buffer 210a, the second lower buffer 230a, the first upper buffer 210b, and the second upper buffer 230b may include various materials and may be formed of the same material or different materials.
[0097] For example, a first loading target component 220 a may be loaded on the first tray 100 a , and a second loading target component 220 b may be loaded on the second tray 100 b .
[0098] In an embodiment, each of the first loading target component 220a and the second loading target component 220b may be a display panel. However, the present disclosure is not limited thereto. For example, the first loading target component 220a and the second loading target component 220b may each be various components included in a display device, and the first tray 100a and the second tray 100b may also accommodate different components.
[0099] With the above reference Figure 2 Similar to the description, each of the first tray 100a and the second tray 100b may include a support portion SU, a container portion PO, and a stopper (eg, a first stopper ZS1 and / or a second stopper ZS2).
[0100] In an embodiment, the first tray 100a may include a first stopper ZS1 protruding a first length in the third direction DR3, and the second tray 100b may include a second stopper ZS2 protruding a first length in the third direction DR3. The first stopper ZS1 and the second stopper ZS2 may correspond to the above reference Figure 2 , Figure 3 and Figure 4 To avoid overlapping descriptions, the subsequent description will focus on the second stop ZS2.
[0101] In an embodiment, each of the first stopper ZS1 and the second stopper ZS2 may be moved from the container portion (eg, Figure 2 The first stopper ZS1 and the second stopper ZS2 may each have a protrusion length LE1 of a first length. In other words, each of the first stopper ZS1 and the second stopper ZS2 may protrude from the base of the container portion PO in the third direction DR3 by the protrusion length LE1 of the first length.
[0102] Each of the first lower buffer 210a, the second lower buffer 230a, the first upper buffer 210b, and the second upper buffer 230b may have substantially the same shape. Therefore, in order to avoid overlapping descriptions, the subsequent description will focus on the second lower buffer 230a and the second upper buffer 230b.
[0103] For example, in a cross-sectional view, each of the second lower buffer 230a and the second upper buffer 230b may have a thickness LE2 of the second length. For example, the thickness LE2 of each of the second lower buffer 230a and the second upper buffer 230b may mean a length in the third direction DR3. For example, the second length may be about 1.6 mm.
[0104] In an embodiment, the first length may be greater than the second length. For example, if the second length is about 1.6 mm, the first length may exceed about 1.6 mm. In other words, the protruding length LE1 of each of the first stopper ZS1 and the second stopper ZS2 may be greater than the thickness LE2 of each of the second lower buffer 230a and the second upper buffer 230b.
[0105] Each of the first stopper ZS1 and the second stopper ZS2 may press the buffer 200 disposed below. For example, the second stopper ZS2 may press the second lower buffer 230a disposed below. In an embodiment, the second lower buffer 230a may be pressed down by the second stopper ZS2 of the second tray 100b by a third length LE3.
[0106] In addition, each of the first stopper ZS1 and the second stopper ZS2 may be spaced apart from the loading target component (eg, the first loading target component 220 a and the second loading target component 220 b ).
[0107] In an embodiment, the third length LE3 may be smaller than the first length. In other words, the length of the second lower buffer 230a recessed by the second stopper ZS2 may be smaller than the protruding length LE1 of the second stopper ZS2.
[0108] In an embodiment, the third length LE3 may be about 1.6 mm or more and about 2.1 mm or less.
[0109] When the third length LE3 (i.e., the length of the second lower buffer 230a recessed by the second stopper ZS2) is less than about 1.6 mm, the force for fixing the loading target component (e.g., the first loading target component 220a) disposed below may be weak. Figure 2 When the placement area FA and the edge area SA), it may be due to the support portion (for example, Figure 2 The supporting part SU) is damaged by collision.
[0110] On the other hand, when the third length LE3 (i.e., the length of the second lower buffer 230a recessed by the second stopper ZS2) exceeds about 2.1 mm, excessive pressure may be applied to the loading target part 220 disposed below. For example, pressure may be applied in the third direction DR3. Therefore, the loading target part 220 may be damaged in a plane direction (e.g., a direction parallel to a plane defined by the first direction DR1 and the second direction DR2).
[0111] Figure 7 yes Figure 6 A magnified view of area A. Figure 7 As shown in , the second lower buffer 230a may be pressed down by the second stopper ZS2. For example, the second length between the upper surface USB of the second lower buffer 230a and the lower surface USP of the second lower buffer 230a (i.e., the thickness LE2 of the second lower buffer 230a) may be greater than the length of the second lower buffer 230a recessed by the second stopper ZS2 (i.e., the third length LE3). Therefore, when the second stopper ZS2 presses the second lower buffer 230a, the second stopper ZS2 may be spaced apart from the first loading target part 220a, and the first loading target part 220a may be prevented from being damaged due to impact.
[0112] As mentioned above Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As described, the tray module 1 may include a first tray 100a, a first buffer 210, and a second buffer 230. The first tray 100a may include a container portion PO defining a seating area FA and an edge area SA, and a first stopper ZS1 protruding from a base of the container portion PO to have a protruding length LE1 of a first length in a third direction DR3, the seating area FA including a seating surface SS parallel to a plane defined by the first direction DR1 and the second direction DR2, and the edge area SA having a predetermined width W1 surrounding the seating area FA. The first buffer 210 may be disposed on the first tray 100a. The second buffer 230 may be disposed on the first buffer 210 and may have a thickness LE2 of a second length. Due to the edge area SA defined in the first tray 100a, the loading target part 220 may be prevented from being damaged due to movement.
[0113] In addition, since the second tray 100b includes the second stopper ZS2, a buffer (e.g., the second lower buffer 230a) on the first tray 100a and below the second tray 100b can be pressed. Therefore, the impact applied to the loading target component (e.g., the first loading target component 220a) can be buffered without high-cost components.
[0114] The tray module 1 according to the embodiment may be applied to a manufacturing process of a display device included in a computer, a notebook computer, a mobile phone, a smart phone, a smart tablet, a PMP, a PDA, an MP3 player, etc.
