Description

Technical Field

[0001] The utility model relates to the field of display panel manufacturing, in particular to a packaging box for carrying a display panel and components thereof. Background Art

[0002] Display panels are important components of electronic products with display functions, such as televisions, computers and mobile phones. They need to be transported to the assembly or processing workshop of electronic products by means of a transport device. However, both the finished display panels and the flat glass as their components need to be packaged and transported in packaging boxes to ensure the safe transportation of the finished display panels and their components.

[0003] In order to make the existing flat glass packaging boxes waterproof, a special aluminum foil composite foam is placed at the bottom of the box to reduce the penetration of water vapor, and then the flat glass and other components are stacked on top of the aluminum foil composite foam. In order to separate the flat glass, the spacer foam placed between each two flat glass is ordinary foam to reduce costs. When faced with two types of foam, operators may confuse and assemble them incorrectly, resulting in ineffective water blocking during transportation. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0023] like Figure 1 As shown, one embodiment of the present invention provides a packaging box 1, which contains a plurality of flat glass sheets so as to facilitate the transportation of the plurality of flat glass sheets. The packaging box 1 comprises a bottom plate 10 and four side walls 11 arranged along the edges of the bottom plate 10.

[0024] The bottom plate 10 is in a rectangular plate shape, and includes an upper surface 101 and a groove 13 formed along the periphery of the upper surface 101. The upper surface 101 and the bottom surface of the groove 13 form a step structure to prevent water in the groove 13 from penetrating into the flat glass on the upper surface 101. The bottom plate 10 and the side wall 11 together form a receiving space S for placing the flat glass.

[0025] It should be noted that during the transportation of the flat glass, water vapor in the air, or rain or snow in bad weather, may enter the packaging box 1 through the gaps in the bottom plate 10 and contaminate the flat glass.

[0026] The packaging box 1 of one embodiment of the present invention is to achieve a waterproof effect, such as Figure 2 As shown, the upper surface 101 of the bottom plate 10 in the packaging box 1 is covered and bonded with a layer of plastic sheet 12. The upper surface 101 of the bottom plate 10 and the plastic sheet 12 are integrally formed. Specifically, the plastic sheet 12 is a hot-melt plastic bonded to the bottom plate 10 by hot-melt. As the hot-melt plastic constituting the plastic sheet 12, for example, PP, PS, PVC, ABS, PC, and silicone can be cited. Preferably, as Figure 3 and Figure 4 As shown, the plastic sheet 12 does not completely cover the bottom plate 10 of the packaging box 1 , that is, at least a portion of the bottom plate 10 is exposed from the accommodating space S.

[0027] Grooves 13 whose height is lower than the upper surface 101 of the bottom plate 10 are respectively arranged on the four sides where the bottom plate 10 and the side wall 11 meet, and the grooves 13 surround the area where the plastic sheet 12 is arranged. The plastic sheet has good waterproof and anti-condensation properties, which can inhibit water vapor from penetrating upward from the bottom of the packaging box 1. At the same time, the bottom plate 10 covered with the plastic sheet 12 can also inhibit water vapor from condensing on the bottom plate 10. In addition, by arranging the grooves 13 on the four sides of the bottom plate 10, a small amount of water generated during the transportation of the flat glass, such as water droplets condensed on the side wall 11 of the packaging box 1, can be collected by the grooves 13, which can prevent the water droplets from dripping down to the bottom plate 10 and soaking the flat glass. Furthermore, a plurality of water guide grooves (not shown) can also be concavely arranged on the plastic sheet 12, and the water guide grooves run from one side of the plastic sheet 12 to the opposite side.

[0028] like Figure 1 As shown, two or more pieces of flat glass 3 are sequentially placed in the receiving space S, and a spacer 4 is placed between any two pieces of flat glass 3, wherein the spacer 4 can be made of elastic materials such as foam material or pearl cotton to ensure that the display panel is not damaged during transportation. The size of the spacer 4 is adapted to the size of the receiving space S, and the size of the flat glass 3 is adapted to the size of the bottom plate 10. The receiving space S is used to accommodate the flat glass 3, and the flat glass 3 is usually rectangular, so the cavity 100 of this embodiment is also rectangular, but it does not mean that other shapes are not possible.

[0029] like Figure 1 As shown, the inner wall of at least one side wall 11 is formed with a plurality of positioning protrusions 112 and a plurality of engaging grooves 113, and the plurality of positioning protrusions 112 and the plurality of engaging grooves 113 are alternately arranged. The positioning protrusions 112 are formed by protruding and extending from the inner wall of the side wall 11 toward the center of the bottom plate 10. The positioning protrusions 112 are in contact with the side walls of the plurality of flat glass sheets and the side walls of the spacer 4 to prevent the plurality of flat glass sheets from shaking in the packaging box 1 during transportation.

[0030] The engaging groove 113 is recessed downward from the end of the side wall 11 away from the bottom plate 10 and is opened toward the center of the bottom plate 10. The spacer 4 is provided with a protruding engaging portion 401, which is engaged in the engaging groove 113 to prevent the spacer 4 from moving out of position.

[0031] Compared with the prior art that reduces the upward penetration of water vapor by placing aluminum foil composite foam at the bottom of the packaging box, the packaging box 1 of the utility model composites the waterproof plastic sheet 12 to the bottom of the packaging box 1 by hot melting, and the operator no longer needs to place aluminum foil composite foam, reducing the risk of operators misplacing ordinary foam during operation.

[0032] The manufacturing method of the packaging box of the utility model is further described below.

[0033] The manufacturing method of the packaging box of the utility model comprises:

[0034] Grooves 13 are provided on four sides of the bottom plate 10 along the side walls 11 and are lower than the upper surface of the bottom plate 10 ;

[0035] Place the packaging box 1 into the mold, and then place the plastic sheet 12 on the bottom plate 10;

[0036] Closing the mold, and heating the mold by steam to melt the plastic sheet 12 to combine with the base plate 10; and

[0037] The packaging box 1 is obtained by cooling and demoulding.

[0038] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
