With the continuous development of display panel manufacturing technology, people put forward higher requirements on the performance and display effect of display panels and display devices.
As shown in fig. 1, fig. 1 is a schematic view of a transfer package structure of a substrate provided in the prior art. In the manufacturing process of the display panel, other components, such as a substrate or each film layer, are also required to be transferred and assembled. In the prior art, each functional film 102 is typically attached to a spacer 101, and the spacer 101 is disposed within the package 100 and defined by a limiter 103. To improve the transfer and work efficiency of the package 100, the pads 101 are typically stacked within the package 100. When the package box 100 is transported, the package box 100 is often subjected to external force, so that the package box 100 is inclined. When the packing box is inclined, the functional film layer 102 on the gasket 101 is prevented from moving sideways and is contacted or collided with the side edge of the packing box 100, so that the thinner functional film layer 102 is deformed or damaged, and the manufacturing cost of the display panel is increased.
The embodiment of the application provides a packing material gasket and a protection device, which are used for effectively solving the problem that a film layer is easy to contact with the side edge of a packing box to deform or damage when the packing box transfers a thinner film layer.
Fig. 2 is a schematic structural diagram of a packing spacer according to an embodiment of the present application, as shown in fig. 2. Specifically, the packing spacer includes a bearing body 201 and a retaining wall 202. Specifically, the carrier body 201 has a carrier surface 205. Since the corresponding substrate or each film layer in the display panel is generally a flat film layer, in the embodiment of the present application, the carrying surface 205 is preferably a flat surface. Further, when the packing material gasket needs to bear or transfer the film layer on the special-shaped surface, the shape of the bearing surface 205 of the packing material gasket can be set according to the shape of the corresponding special-shaped surface, so that the bearing surface 205 can maximally ensure the contact area between the packing material gasket and the required bearing film layer, and the specific shape is not described in detail herein.
When the bearing surface 205 is a flat surface, the retaining wall 202 is further disposed on the bearing surface 205. In an embodiment of the present application, the retaining wall 202 may be directly disposed on the surface of the bearing surface 205. Such as the retaining walls 202, are provided at positions near four corner regions of the carrier body 201.
Specifically, in the following embodiment, four retaining walls 202 are disposed on the bearing surface 205, and each retaining wall 202 is disposed at a position near four corners of the bearing body 201. At this time, the four retaining walls 202 define a rectangular area, such as the corresponding substrate bearing area 203. When the substrate or the film layer is transferred by using the packing material pad, the film layer to be transferred is directly placed in the substrate bearing area 203.
In the embodiment of the present application, since the retaining wall 202 is disposed on the carrying body 201, the film to be transferred is placed in the substrate carrying area 203 during transferring. When the packing material gasket is acted by external force, if the packing material gasket is inclined, the inner film layer of the packing material gasket is inclined. However, when the film layer is inclined, the retaining wall 202 is arranged at the edge 204 of the film layer to be transferred, and the retaining wall 202 can effectively block the film layer to be transferred, so that the film layer is prevented from contacting with the side wall of the packaging box, and the film layer is effectively protected.
Further, as shown in fig. 3, fig. 3 is a schematic structural diagram of a film layer to be transferred according to an embodiment of the present application. The film layer to be transferred in the embodiment of the application is mainly of a laminated structure. The film layer to be transferred can be a two-layer stacked structure. In the following embodiments, the laminated substrate is exemplified by a first substrate 301 and a second substrate 302.
Specifically, the first substrate 301 and the second substrate 302 are stacked, and the second substrate 302 is disposed above the first substrate 301. In the embodiment of the application, the area of the second substrate 302 is larger than the area of the first substrate 301. Therefore, when the first substrate 301 and the second substrate 302 are bonded, the geometric center of the first substrate 301 and the geometric center of the second substrate 302 can be overlapped, so as to ensure a certain symmetry between the two substrates.
Preferably, when the first substrate 301 is an optical film of a display panel, and the second substrate 302 is a hardened layer, the hardened layer may be attached above the optical film, and the hardened layer has a hardness greater than that of the optical film, and then the hardened layer is prevented from being attached to a packing material pad and transferred. Or the first substrate 301 is a functional film layer, and the second substrate 302 is a corresponding hardened layer, which will not be described in detail herein.
Specifically, in the process of setting, as shown in fig. 4, fig. 4 is a schematic structural diagram of a packing material gasket provided in an embodiment of the present application. Fig. 5, fig. 5 is a schematic structural diagram of the packing spacer according to an embodiment of the present application. In combination with the corresponding structures in fig. 2-4, in the embodiment of the present application, after the first substrate 301 and the second substrate 302 are stacked, they are transferred to the carrier body 201 of the packing spacer. Specifically, the first substrate 301 may be disposed in a region corresponding to the carrying surface. In the embodiment of the present application, the first substrate 301 is placed in a bearing area surrounded by four retaining walls 202.
In the embodiment of the present application, the height of the retaining wall 202 is smaller than the distance between the second substrate 302 and the surface of the carrier 201, so as to ensure that the first substrate 301 can be directly adsorbed on the surface of the carrier 201. Meanwhile, a certain gap value is reserved between the retaining wall 202 and the side edge of the first substrate 301. In the embodiment of the application, the gap value can be set to be larger than 2mm, or the gap value can be adjusted according to the size of the corresponding substrate. Preferably, in the embodiment of the present application, when the retaining wall 202 is provided, the retaining wall may be symmetrically disposed with respect to the central axis of the bearing surface, so as to reasonably utilize the bearing area of the bearing surface.
Meanwhile, as shown in fig. 4, the area of the second substrate 302 is larger than that of the first substrate 301, and the corresponding bearing area of the bearing body 201 is larger than that of the second substrate 302. Further, when the substrate is transferred onto the carrier 201, the projection of the second substrate 302 on the carrier 201 may be at least partially overlapped with the projection of the retaining wall 202 on the carrier 201. Thus, the first substrate 301 is defined in the bearing area surrounded by the retaining wall 202, and two ends of the second substrate 302 are correspondingly disposed on the retaining wall 202 and do not contact with the retaining wall 202.
When the substrates are subjected to lateral forces, the retaining wall 202 can block the first substrate 301, preventing the first substrate 301 and the second substrate 302 from contacting the sidewalls of the package. Meanwhile, the retaining wall 202 can also support the second substrate 302 above the retaining wall to a certain extent, so as to place the second substrate 302 in breakage.
Referring to fig. 5, further, in the embodiment of the application, when the retaining wall 202 is disposed, the retaining wall 202 is disposed at least around a portion of two adjacent sides of the first substrate 301.
Specifically, the retaining wall 202 may include a first blocking portion 2021 and a second blocking portion 2022. Wherein the first blocking portion 2021 may be connected or disconnected with the second blocking portion 2022. When the first blocking portion 2021 is connected to the second blocking portion 2022, a structure as in fig. 5 may be formed. When there is a certain gap between the two, the retaining wall 202 still has a blocking effect.
Preferably, the retaining wall 202 may be configured in an "L" shape or a "T" shape, etc. And the retaining walls 202 are correspondingly disposed at four corners of the first substrate 301. In the embodiment of the present application, when the first blocking portion 2021 and the second blocking portion 2022 are disposed, the first blocking portion 2021 may be parallel to the side a of the first substrate 301, and the second blocking portion 2022 may be parallel to the side b of the first substrate 301. Meanwhile, the gap value between the side a and the side b to the corresponding blocking portion can be made the same. The side a and the side b are two adjacent sides of the first substrate 301.
Preferably, in the embodiment of the present application, when the retaining wall is provided, a plurality of blocking strips may be further provided at the area near the peripheral side edge of the first substrate 301. The plurality of barrier ribs can further define sides of the first substrate. When the retaining wall at a certain corner falls off, the blocking strip arranged at the corresponding side edge region can block the first substrate effectively, so that the problem that the substrate is deformed due to contact with the side wall of the transfer device is solved.
Furthermore, in the embodiment of the present application, when the first substrate 301 moves laterally, different blocking portions of the retaining wall 202 can limit the first substrate 301 in different directions, so as to effectively prevent the first substrate 301 from moving to contact with the side edges of the packaging box.
Further, as shown in fig. 4, the area of the second substrate 302 is larger than that of the first substrate 301. Thus, in an embodiment of the present application, the second substrate 302 may include a fitting portion 3012 and an extending portion 3011.
The attaching portion 3012 is a portion where the second substrate 302 is attached to the first substrate 301, and the protruding portion 3011 is a portion beyond the edge of the first substrate 301. In order to ensure the performance of the retaining wall 202, in the embodiment of the present application, the projection of the protruding portion 3011 on the carrying body 201 may coincide with the projection of the retaining wall 202 on the carrying body 201. When the protruding portion 3011 of the second substrate 302 is bent downward under the force, the retaining wall 202 can have a better supporting effect, so that the substrate is effectively protected.
Preferably, in the embodiment of the present application, the height of the retaining wall 202 may be smaller than the thickness of the first substrate 301. Thereby ensuring that the first substrate 301 can be closely attached to the carrying surface.
Further, in the embodiment of the present application, the packing spacer may further include an elastic member 333. Wherein the elastic member 333 may be disposed above the retaining wall 202. If the elastic member 333 is disposed above the intersection area of the first blocking portion 2021 and the second blocking portion 2022 of the retaining wall 202, or if the elastic member 333 is disposed only above one side of the first blocking portion 2021 and the second blocking portion 2022. And the height of the elastic member 333 is at least greater than the gap between the second substrate 302 and the retaining wall 202.
When the second substrate 302 moves laterally, the elastic member 333 can effectively block the second substrate 302, so as to effectively prevent the second substrate 302 from being deformed due to collision with the side edge of the transfer packaging box.
Preferably, in the embodiment of the present application, the elastic member 333 may be selected from a rubber body with a certain elasticity or a spring with a better elasticity. Meanwhile, the elastic member 333 and the second substrate are not in contact with each other. The specific configuration can be set according to the size and specification of the substrate to which the packing material gasket is transferred.
Further, as shown in fig. 6, fig. 6 is a schematic view of another retaining wall structure on a bearing body according to an embodiment of the present application. In the embodiment of the present application, when the retaining wall 202 is disposed on the carrying body 201, the retaining wall 202 may be disposed only at two corner regions opposite to the first substrate 301. At this time, only two retaining walls 202 need to be provided at a pair of corners of the first substrate 301. The structure of the retaining wall 202 may be configured as in the embodiments described above.
Meanwhile, the retaining wall 202 is not provided at the other diagonal region of the first substrate 301, and the barrier rib 208 is provided at the other diagonal region. At this time, the blocking strip 208 is disposed near the outer edge of the first substrate 301, and a certain distance is reserved between the blocking strip and the first substrate 301. In embodiments per se, a plurality of barrier ribs 208 may be provided at side a and side c opposite side a. Meanwhile, a blocking bar 208 is provided at the other diagonal. When the substrate is moved, two retaining walls 202 disposed at a pair of corner regions may define the first substrate 301 on a plane in which the first substrate moves, and a blocking bar 208 disposed near the outer edge may define the first substrate in a moving direction thereof. Furthermore, in the embodiment of the application, the problem that the substrate collides with the side wall of the transfer device to deform can be effectively prevented.
In the embodiment of the application, the number and the distance of the blocking strips can be set according to the size of an actual product. The height of the blocking strip can be set with reference to the retaining wall, and detailed description thereof is omitted.
Further, in the embodiment of the present application, the material of the carrying body 201 may be selected as a hollow plate material. The hollow plate can be a plate material prepared by extrusion molding with polypropylene or polyethylene as a main raw material. The hollow plate is of a hollow structure, and has the advantages of light weight, no toxicity, no pollution, shock resistance, corrosion resistance and the like, so that the hollow plate has better bearing performance while being light in weight.
Meanwhile, when the carrying body 201 is provided as a hollow plate, the material surface of the hollow plate has a high hardness, and a high flatness. When the first substrate is placed on the hollow plate, the first substrate has a good adsorption effect, so that the substrate is prevented from shaking during transfer and transportation.
Further, when the retaining wall is provided, the retaining wall can be made of any one of silica gel, ethylene-vinyl acetate copolymer and polyurethane plastic, or other components with better elastic performance.
Fig. 7 is a schematic structural diagram of a protection device according to an embodiment of the present application. In the embodiment of the application, a protection device is also provided. The protection device is mainly applied to bearing and transferring of the substrate and each film layer in the display panel. In the transferring process, the packing material gasket is placed in the accommodating cavity of the protecting device and is transferred.
In particular, the guard may include a case 600. Within the housing 600 is a receiving cavity 601. Meanwhile, a packing spacer 602 is provided in the accommodating chamber 601. In order to enhance the transfer effect of the protection device, in the embodiment of the present application, the packing spacer 602 may be stacked in the case 600, as shown in the two-layer structure of fig. 6. In each layer of packing spacer 602, a carrying body 201, and a first substrate 301, a second substrate 302, and a retaining wall 202 disposed on the carrying body 201 are correspondingly disposed.
In the embodiment of the present application, when the packing spacer 602 of the second layer is provided, the carrier 201 in the second layer can be directly prevented from being on the second substrate 302. In the embodiment of the application, the retaining wall is arranged on the bearing surface of the bearing main body in the packing material gasket, so that a limiting piece in the prior art, which is directly near the inner side wall of the protecting device, is replaced. When the retaining wall is transported and transferred, the four corners of the first substrate are stressed, the four corners of the second substrate arranged on the first substrate are not stressed, and in addition, the retaining wall can effectively limit the movement of the first substrate in the shaking process. Therefore, the problem that the laminated substrate is easy to collide with the side wall of the packaging box to deform in the transferring process is effectively solved.
