The present disclosure provides a packaging structure, see fig. 1, comprising a pallet TT and a carrier MM, which cooperate with each other. In fig. 1, only one transport means MM in the packaging structure is shown, the other transport means MM' in the packaging structure being hatched. The present disclosure may also provide the pallet TT described above and the transport MM described above.

Fig. 4 shows a schematic view of the structure of a tray TT in one embodiment of the present disclosure, wherein the tray TT has a receiving groove T1 and a connector T2. In the embodiment shown in fig. 4, the tray TT has three storage grooves T1, and fig. 4 shows only the lower two storage grooves T1' in position, and the approximate positions thereof are shown by line hatching. It is understood that in other embodiments of the present disclosure, the tray TT may have one receiving groove T1 therein, or may have a plurality of receiving grooves T1 therein. When the tray TT has a plurality of receiving grooves T1, the plurality of receiving grooves T1 may be arranged linearly, may be arranged in a rectangular array, or may be arranged in other ways, which is not particularly limited in the present disclosure.

Fig. 5 shows a schematic diagram of a transport MM in one embodiment of the present disclosure. Referring to fig. 5, the carrier MM includes a display module MDL and a positioning member DD detachably connected.

Referring to fig. 1, the transport member is at least partially accommodated in the accommodating groove T1. The positioning piece DD is fixed on the outer surface of the display module MDL and is detachably connected with the connecting piece T2. In the packaging structure of the present disclosure, the positioning member DD is connected with the connecting member T2, so that the relative position between the display module MDL and the tray TT is fixed. Like this, packaging structure is in commodity circulation transportation, is difficult to take place relative rocking between display module assembly MDL and the tray TT, and then reduces display module assembly MDL and tray TT collision, cuts to scratch, rubs etc. and the risk of damage, reduces the loss of display module assembly in commodity circulation in-process. When the display module MDL is required to be used, the conveying member MM can be taken out of the tray TT, and then the positioning member DD is removed, so that the display module MDL to be further assembled is obtained.

The structure, principles and effects of the carrier MM, tray TT and packaging structure provided by the present disclosure are further explained and illustrated below with reference to the accompanying drawings.

Referring to fig. 4, the tray TT has a receiving groove T1 for receiving the display module MDL. In the packaging structure, the display module MDL may be at least partially accommodated in the accommodating groove T1. In one embodiment of the disclosure, the display module MDL is completely accommodated in the accommodating groove T1. In transportation, a plurality of packaging structures may be stacked and transported in sequence.

Referring to fig. 4, the tray TT may have one receiving groove T1, or may have a plurality of receiving grooves T1; each accommodating groove T1 is used for accommodating one display module MDL. The accommodating groove T1 may be an upwardly open groove, and the overall shape thereof may be matched with the overall shape of the transporting member MM, so that the transporting member may be at least partially sunk into the accommodating groove T1. For convenience of description, in the present disclosure, a direction in which the receiving groove T1 is opened may be defined as an upper direction. Thus, when the packaging structure is normally placed, the surface of the display module MDL exposed by the accommodating groove T1 is an outer surface, and the outer surface faces upwards; the bottom of the accommodating groove T1 is used for bearing the display module MDL below the display module MDL. The depth of the accommodating groove T1 may be determined according to needs, so that the display module MDL can be at least partially accommodated in the accommodating groove T1. It is understood that the bottom surface of the accommodating groove T1 may be a plane or may undulate according to the undulation of the lower surface (the surface facing the tray TT) of the display module MDL.

In some embodiments, referring to fig. 4, the tray TT may further include a positioning slot T3 located around the accommodating slot T1, where the positioning slot T3 may be a slot with a downward recess and an upward opening, or may be a slot with an upward projection and a downward opening. When two trays TT are stacked up and down, each positioning clamping groove T3 of the two trays TT can be aligned and inserted in a one-to-one correspondence mode, so that the relative height between the upper tray TT and the lower tray TT is limited, and the display module MDL in the tray TT below is prevented from being extruded by the tray TT above.

Further, a step-shaped positioning wall can be formed on at least part of the groove wall of the positioning groove T3, so that the positioning groove T3 has stronger supporting capability and more accurate positioning capability.

Referring to fig. 4, the number, size, shape and position of the positioning slots T3 on the tray TT may be set independently according to needs, for example, the tray TT may be provided with positioning slots T3 of a plurality of different sizes.

In some embodiments, referring to fig. 4, the edge of the tray TT may be further formed with an edge positioning groove T4, and the edge positioning groove T4 may be protruded upward or recessed downward. When two trays TT are stacked up and down, the edge positioning grooves T4 of the two trays TT can be aligned and inserted in a one-to-one correspondence mode, so that the relative height between the upper tray TT and the lower tray TT is limited, and the display module MDL in the tray TT below is prevented from being extruded by the tray TT above. Further, the edge positioning groove T4 can also be provided with a step-shaped positioning wall, so that the bearing capacity and positioning accuracy of the edge positioning groove T4 are enhanced.

In some embodiments, referring to fig. 4, trays TT may be arranged axisymmetrically.

In the present disclosure, referring to fig. 4 and 1, a connection T2 may be provided on the tray TT. The connecting piece T2 is used for being connected with a positioning piece DD of the conveying piece MM, and fixing of the display module MDL is achieved. The connecting member T2 may be disposed in the accommodating groove T1, or may be disposed outside the accommodating groove T1.

In one embodiment of the present disclosure, referring to fig. 4, the receiving groove T1 has a first positioning groove T11 for cooperating with the positioning member DD, and the connection member T2 may be disposed in the first positioning groove T11. In this way, the connection element T2 and the positioning element DD can be made to sink, avoiding affecting the stacking of the packaging structure.

In some embodiments, the number of connectors T2 may be a plurality; the positioning piece DD is detachably connected with at least two connecting pieces T2. Like this, setting element DD can be fixed by two at least connecting pieces T2, improves setting element DD's stability, and then improves display module assembly MDL by fixed stability. Further, a plurality of connectors T2 are disposed on both sides of the receiving groove T1, respectively.

In one embodiment of the disclosure, the tray TT has a plurality of accommodating grooves T1, and the number of the connecting pieces T2 is plural and divided into a plurality of groups corresponding to the respective accommodating grooves T1 one by one, and each group of connecting pieces T2 is disposed corresponding to one accommodating groove T1. In this way, the transport member MM accommodated in the accommodating groove T1 can be engaged with the connection member T2 in the connection member group corresponding to the accommodating groove T1. Illustratively, referring to fig. 4, each receiving groove T1 has two oppositely disposed first positioning grooves T11, and one connecting member T2 is disposed in each first positioning groove T11. Thus, the fixing effect on the positioning member DD can be improved.

In one embodiment of the present disclosure, referring to fig. 4, the connection T2 may be a connection post, for example, an upwardly extending connection post. Correspondingly, referring to fig. 5, the positioning pieces DD are provided with positioning holes D3 corresponding to the connecting columns one by one. Referring to fig. 1 and 2, when the positioning member DD is engaged with the connecting member T2, the connecting post may be inserted into the positioning hole D3, so that the displacement of the positioning member DD in a plane perpendicular to the extending direction of the connecting post (in most cases, the plane is close to the horizontal plane) is restricted, thereby reducing or eliminating the shaking of the display module MDL in the receiving groove T1. Of course, in other embodiments of the present disclosure, the connecting piece may also be a positioning hole formed on the tray TT, and the positioning piece DD may be provided with a connecting post matched with the positioning hole, so as to enable the positioning piece and the connecting piece to be detachably connected.

In one embodiment of the present disclosure, the radius of the connecting post may be slightly larger than the radius of the positioning hole D3, so as to facilitate insertion of the connecting post into the positioning hole D3, facilitate assembly of the packaging structure, and reduce material loss. Further, the radius of the positioning hole D3 may be greater than the radius of the connection post by more than 0.2 mm. Illustratively, the radius of the locating hole D3 is 0.3 millimeters greater than the radius of the connecting post. Thus, even if there is a certain process error between the positioning hole D3 and the connecting post during the preparation, the radius of the connecting post can be slightly larger than that of the positioning hole D3, so that the connecting post can still be ensured to be inserted into the positioning hole D3.

As an example, the radius of the connecting post is 3.2 mm and the radius of the positioning hole D3 is 3.5 mm. Thus, the radius of the positioning hole D3 is 0.3 mm larger than the radius of the connection post. On the one hand, this facilitates the cooperation of the connecting post with the positioning hole D3; on the other hand, even if the manufacturing process of the connecting column and the positioning piece DD has a process error, the cooperation of the connecting column and the positioning hole D3 can still be ensured, the influence of the process error is eliminated, the lower-precision manufacturing process is allowed to be adopted for manufacturing the tray TT and the positioning piece DD, and the cost of the tray TT and the positioning piece DD is further reduced.

In some embodiments of the present disclosure, in the packaging structure, a gap exists between an edge of the display module MDL and at least a portion of the edge T10 of the receiving groove T1. In other words, when the display module MDL is fixed on the tray TT by the positioning member DD, at least a portion of the edge of the display module MDL is not in contact with at least a portion of the edge of the accommodating groove T1, so as to reduce the risk of damage of the display module MDL due to collision with the edge of the accommodating groove T1.

In one embodiment of the present disclosure, a minimum gap between an edge of the display module MDL and an edge of the receiving groove T1 may be determined according to the matching precision of the positioning member DD and the connecting member T2, so that the minimum gap is not less than the matching precision. In this way, even if a certain assembly error exists, the edge of the display module MDL and the edge of the accommodating groove T1 can be prevented from being collided.

Illustratively, the positioning member DD has a positioning hole D3, and the connecting member T2 is a connecting post which mates with the positioning hole D3. The difference between the radius of the positioning hole D3 and the radius of the connecting column is X. When the connecting column is aligned with the axis of the positioning hole D3, the distance between the edge of the display module MDL and the edge of the receiving slot T1 is at least X. Therefore, even if the display module MDL shakes, the edge of the display module MDL can not collide with the edge of the accommodating groove T1, and the risk of damage of the display module MDL due to collision is reduced. Even if the process error factor is considered, especially if the dimension change of the edge of the accommodating groove T1 due to the process error is considered, the collision between the accommodating groove T1 and the display module MDL can be significantly reduced.

In some embodiments of the present disclosure, the display module MDL may be a component for implementing a display function, which may have a display panel and other materials matched with the display panel. The display panel may be an OLED (organic light emitting diode) display panel, and particularly may be a flexible OLED display panel, for example. In the display module MDL, the front surface of the display panel may be provided with a cover plate (e.g., a glass cover plate), a protective film (e.g., a flexible organic protective layer), or other protective structure for protecting the display panel. In the display module MDL, the back surface of the display panel may be provided with one or more of a circuit board, a driving chip, a chip covering tape, a protection cover, a back case, and the like. Of course, in other embodiments of the present disclosure, the display module may be the display panel or the material itself, or a combination of multiple display panels and materials. For example, in the present disclosure, a display panel, a glass cover plate, a protective film, etc. may also be considered as a display module of the present disclosure, and may also be combined with a positioning member to form a transport member in an embodiment of the present disclosure.

Referring to fig. 9, in some embodiments, the display module MDL may include a display panel PNL and a back case SUS connected to a rear surface of the display panel PNL; the positioning member DD may be detachably attached to the back case SUS. In the packing structure, the display panel PNL may face the bottom of the receiving groove T1, and the back case SUS may face the outside. Referring to fig. 5, a circuit board M2 (not shown in fig. 9), a driving chip (not shown in fig. 5, not shown in fig. 9), a chip cover tape (not shown in fig. 5, not shown in fig. 9), a protective cover M1 (not shown in fig. 9), and the like may also be provided at the back side of the display panel PNL.

Referring to fig. 9, one end of the back surface of the display module MDL has a binding area (not shown in fig. 9) for binding the driving chip or the circuit board. In the present disclosure, an end of the display module MDL where the binding area is provided may be defined as a lower end B1, and an end far from the binding area may be defined as a top end B2. In some embodiments, the circuit board M2, the protective cover M1, etc. are disposed near the lower end B1; the positioning piece DD is detachably connected with the back shell at the top end B2 of the display module MDL. Thus, the first positioning groove T11 may be provided with an end portion of the receiving groove T1 (an end portion for receiving the lower end B1 of the display panel PNL)

In some embodiments, the display module MDL is disposed in each structure on the back of the display panel PNL, and a part of the structures may extend beyond the edge of the display panel PNL, so that the edge of the display module MDL extends beyond the edge of the display panel PNL. For these structures beyond the edge of the display panel PNL, the receiving groove T1 may be provided with a corresponding positioning groove for receiving.

In one embodiment of the present disclosure, referring to fig. 2 to 5, both sides of the protective cover M1 (both sides in the row direction of the display panel PNL) have positioning branches M11 protruding from the edge of the display panel PNL; the accommodating groove T1 is provided with a second positioning groove T13 matched with the positioning branch M11. In the carrier MM, the positioning branch M11 may be accommodated in the second positioning slot T13. Further, a smaller gap may be formed between the edge of the positioning branch M11 and the edge of the adjacent second positioning groove T13, so that the second positioning groove T13 can fix the positioning branch M11, thereby fixing the protective cover M1 and fixing the display panel PNL. Thus, the relative shaking between the display module MDL and the tray TT can be further reduced.

Alternatively, the gap between the edge of the positioning branch M11 and the edge of the adjacent second positioning groove T13 may be determined according to the precision of the fitting of the positioning member DD and the connecting member T2. For example, the gap between the edge of the positioning branch M11 and the edge of the adjacent second positioning groove T13 may be no greater than the gap between the positioning member DD and the connecting member T2. As an example, the radius of the positioning hole D3 of the positioning member DD is 0.3 mm larger than the radius of the connection post as the connection member T2; when the tray TT is designed according to the display module MDL, a gap between the edge of the positioning branch M11 and the edge of the adjacent second positioning groove T13 may be made to be 0.3 mm.

In one embodiment of the present disclosure, referring to fig. 2 to 5, a test end M21 (a free end, an end not bound to the display panel PNL) of a circuit board M2 (e.g., a flexible circuit board FPC) protrudes beyond an edge of the display panel PNL; the accommodating groove T1 is provided with a third positioning groove T12 matched with the test end M21. In the carrier MM, the test end M21 may be received in the third positioning slot T12. Further, a larger gap may be formed between the edge of the test end M21 and the edge of the adjacent third positioning slot T12, so that the test end M21 will not touch the edge of the third positioning slot T12, and damage of the test end M21 due to collision is avoided.

Alternatively, the gap between the edge of the test end M21 and the edge of the adjacent third positioning groove T12 may have a width of between 2 and 4 mm; for example, the gap may have a width of 3 millimeters.

In some embodiments, the edge of the display panel PNL and the edge T10 of the receiving groove T1 may have a larger pitch therebetween, for example, a pitch of not less than 2 mm; further, the spacing may be between 2 and 4 millimeters, for example, may be 3 millimeters. In this way, a larger gap is formed between the display panel PNL and the edge of the accommodating groove T1, so as to avoid damage caused by collision between the display panel PNL and the edge T10 of the accommodating groove T1.

In one embodiment of the present disclosure, a distance between an edge of the display panel PNL and an edge T10 of the receiving groove T1 is equal to a distance between an edge of the test end M21 and an edge of the adjacent third positioning groove T12.

In the embodiment of the disclosure, a gap is formed between the display module MDL and the edge of the accommodating groove, so that rubbing and collision between the display module MDL and the edge of the accommodating groove can be avoided, the mounting accuracy can be reduced, the mounting process window is improved, and manual batch mounting is facilitated.

In some embodiments, the material of the back case SUS may be a hard material, such as stainless steel, aluminum alloy, or titanium alloy, to play a supporting role in the display module MDL. The back shell has great hardness, and difficult deformation makes setting element DD can more effectually fix display module assembly MDL on the one hand, and on the other hand setting element DD also is difficult to produce the damage to the back shell. For example, when the positioning member DD is adhered or adsorbed to the back shell SUS, the back shell SUS does not have a risk of stamping nor interfere with the inspection jig.

In one embodiment of the present disclosure, the positioning member DD and the display module MDL may be bonded. Thus, the positioning piece DD is not only convenient to install on the display module MDL, but also convenient to take out from the conveying piece MM. In a further scheme, the positioning piece DD and the display module MDL can also have other binding force besides the binding force, for example, the binding force between the display module MDL and the positioning piece DD can be enhanced by the adsorption force. Of course, in other embodiments of the present disclosure, the positioning member DD and the display module MDL may be connected by other manners, for example, to facilitate the atmospheric pressure to make the positioning member DD be adsorbed on the display module MDL.

Referring to fig. 6 and 2, in some embodiments of the present disclosure, the spacer DD includes a spacer D1 and a pad D2 connected to each other. The locating piece D1 is detachably connected with the connecting piece T2, and the cushion block D2 is detachably connected with the outer surface of the display module assembly MDL. In fig. 2, the position of pad D2 is shown by hatching.

Further, the number of the cushion blocks D2 is plural and arranged along a straight line. Therefore, the bonding strength between the cushion block D2 and the display module MDL can be improved, and the stress balance of the display module MDL can be improved. For example, referring to fig. 6, the number of the pads D2 is two and are respectively connected to both sides of the top end of the display module MDL.

In one embodiment of the present disclosure, referring to fig. 8, the pad D2 includes an organic base layer D21, a pressure-sensitive adhesive layer D22, and a silicone protective film D23 sequentially laminated on the spacer D1. The silica gel protection film D23 is attached to the outer surface of the display module MDL. Like this, cushion D2 is flexible material, and it has certain buffer property, both can avoid the damage to display module assembly MDL, can cushion the possible rocking of display module assembly MDL again. The cushion block D2 is connected with the display module MDL through the silica gel protective film, so that on one hand, the cushion block D2 and the display module MDL can be reliably connected by means of the adhesive force and the adsorption force between the silica gel protective film and the display module MDL. On the other hand, the silica gel protective film has the characteristic of smaller adhesion force, so that the carrier MM can remove the positioning piece DD easily and avoid stamping on the display module MDL.

Alternatively, the material of the organic base layer D21 may be PET (polyethylene terephthalate) or other organic polymer materials.

Alternatively, the mounting of the positioning member DD may be achieved by a single process during the assembly of the transportation member MM. Specifically, a positioning member material may be provided, and as shown in fig. 7, a release layer D24 for protecting a silica gel protective film D23 is disposed on a pad D2 of the positioning member material. During assembly, the release layer D24 can be torn off, and then the silica gel protective film D23 is attached to the display module assembly MDL, so that the conveying member MM is obtained. Thus, in the embodiment of the disclosure, the fixing of the display module can be improved through the low-cost locating piece (the cost of locating piece materials is low), and the risk of damage to the display module caused by rubbing and rubbing with the tray is reduced.

Further, when the transportation member MM is prepared, the mounting of the chip covering tape, the binding of the chip and the mounting of the positioning member DD on the display panel PNL may be completed at the same station, for example, the setting of the chip covering tape, the driving chip and the positioning member DD may be sequentially completed. In this way, the manufacturing costs of the transportation member MM can be further reduced.

In some embodiments, referring to fig. 6, the spacer D1 may have a positioning hole D3 to be engaged with the connection post. Further, the number of the positioning holes D3 on the positioning plate D1 is two, and the positioning holes are respectively located at two sides of the display module MDL.

In one embodiment of the present disclosure, referring to fig. 2, both ends of the positioning sheet D1 are respectively provided with a connection end D11 extending out of the range of the display panel PNL, and the connection end D11 may be accommodated in the first positioning groove T11. The positioning hole D3 is disposed on the connecting end D11, so as to cooperate with the connecting post located in the first positioning slot T11. Further, the connection end D11 extends toward the bottom end B1 of the display module MDL, so that the positioning plate D1 has a U-shape.

In some embodiments, referring to fig. 8, the display module MDL further includes a light-transmitting protective layer PI disposed on a side of the display panel PNL away from the back case SUS. In other words, the light-transmitting protection layer PI is located on the front surface of the display module MDL; in the packaging structure, the light-transmitting protective layer PI is located on the inner surface of the carrier MM.

In one embodiment of the present disclosure, the light transmissive protective layer PI may be a flexible organic protective layer, for example, a polyimide layer. In the related art, due to reasons such as design error gaps of the tray TT, the display module MDL is easy to scratch with the tray TT in the logistics transportation process, so that the edge of the light-transmitting protective layer PI is easy to be bad. Especially when the light-transmitting protective layer is a flexible organic protective layer, the flexible organic protective layer is softer in material quality and is more prone to occurrence of defects. However, in the embodiment of the present disclosure, the display panel PNL is fixed in the tray TT by the positioning member DD, collision between the display panel PNL and the edge of the tray TT is avoided, and thus the reject ratio is reduced.

In some embodiments, referring to fig. 2 and 3, the packaging structure may further include a buffer pad M3, where the buffer pad M3 is accommodated in the accommodating groove T1 to carry the transport member MM, so as to avoid the bottom of the accommodating groove T1 from damaging the transport member, and in particular, to avoid the bottom of the accommodating groove T1 from damaging the display panel PNL.

In some embodiments, the tray TT has a plurality of receiving grooves, and the receiving grooves may be mutually communicated. Therefore, the buffer pads in the accommodating grooves on the tray TT can be connected with each other to form a whole, and paving of the buffer pads is facilitated. Of course, in other embodiments, the accommodating grooves may not be mutually communicated, and each accommodating groove may be independently provided with a cushion pad.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any adaptations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.
