Description

Liquid crystal panel packaging box with buffer piece

Technical Field

The invention relates to the field of packaging of display devices, in particular to a liquid crystal panel packaging box with a buffer piece.

Background

As shown in fig. 1, in general, when the liquid crystal panel 1 is shipped, a liquid crystal glass 10, a COF flexible circuit board 12 bonded to a terminal side of the liquid crystal glass 10, and a PCB 11 with electronic components connected to the COF flexible circuit board 12 are put into a package box 9.

As shown in fig. 1, when the liquid crystal panel 1 is stacked in the packing box 9, a height difference may exist between the liquid crystal glass 10 and the PCB 11 due to the different thicknesses of the liquid crystal glass 10 and the PCB 11. The presence of such a difference in height and the shaking of the COF flexible circuit board 12 cause a problem that the COF flexible circuit board 12 is folded or broken during transportation. At present, the risk of fracture is reduced by placing a buffer positioning block (not shown) at the PCB to reduce the shaking of the COF flexible circuit board 12, but the buffer block has the risk of jumping off and shifting in actual transportation, and limits the automatic line packaging. Further, when the packing case 9 is not filled, it is necessary to fill the packing case 9 by filling a large number of spacer pads (not shown), which causes a large amount of waste of the pads.

Therefore, it is desirable to provide a liquid crystal panel package to solve the above problems.

Detailed Description

The following description of the present invention will be given with reference to the accompanying drawings, and it should be noted that the present invention is not limited to the following embodiments.

Referring to fig. 2, the liquid crystal panel packaging box 100 of the present invention is used for packaging a plurality of liquid crystal panels 1. Each liquid crystal panel 1 includes a liquid crystal glass 10, a PCB 11, and at least one COF flexible circuit board 12 for connecting the liquid crystal glass 10 and the PCB 11.

As shown in fig. 2, the liquid crystal panel packaging box 100 includes a box body 2, an upper cover 3, and a plurality of buffers 4. The cabinet 2 is formed with a receiving space 20 to carry and receive the liquid crystal panels 1 horizontally stacked. The upper cover 3 is mounted on the case 2 to close or seal the accommodating space 20. The buffer member 4 is disposed on the inner top wall 300 of the upper cover, and can extend into the accommodating space 20 to press against different positions of the uppermost liquid crystal panel 1.

In this embodiment, the box 2 and the upper cover 3 have a rectangular parallelepiped shape to conform to the shape of the liquid crystal panel 1.

Referring to fig. 2, a plurality of engaging portions 31 are formed on an inner top wall 300 of the upper cover 3, one end of the buffer member 4 is fixed to the engaging portion 31, and the other end of the buffer member 4 is a free end and extends into the accommodating space 20 to press against the liquid crystal glass 10 of the liquid crystal panel 1 or against the PCB 11 on one side of the liquid crystal glass 10.

More specifically, as shown in fig. 3 and 4, in the present embodiment, the upper cover 3 includes a main plate 301, a receiving groove 302 formed on an inner top wall of the main plate 301, and a side wall 303 located around the main plate 301 and surrounding the receiving groove 302. Wherein the inner top wall of the main plate 301 is the inner top wall 300 of the upper cover 3. The receiving groove 302 is substantially a closed quadrilateral structure. The container 302 is used to combine with a flange 21 on the case 2 (see fig. 2) to mount the upper cover 3 on the case 2, and also to seal the case 2 by the upper cover 3.

As shown in fig. 3 and 4, in the present embodiment, the engaging portion 31 is formed on the inner top wall 300 of the main plate 301 and is adjacent to the accommodating groove 302. The fitting portion 31 is a T-shaped groove, and the cushion member 4 is a T-shaped block to be fitted in the T-shaped groove.

As shown in fig. 2, the buffer 4 is divided into at least two buffers with different sizes, one of the buffers can be pressed against the liquid crystal glass 10 of the liquid crystal panel 1, and the other buffer can be pressed against the PCB 11 on one side of the liquid crystal glass 10. The different-size buffering parts mainly refer to different heights, and certainly, different widths or other sizes.

In this embodiment, the cushioning members 4 are T-shaped blocks having different heights, and these T-shaped blocks are selectively fitted into the fitting portions 31. In particular, said buffer 4 is divided into at least one buffer 4' of small height and at least one buffer 4 "of large height. The buffer 4 'with small height is used for pressing against the PCB 11, and the buffer 4' with large height is used for pressing against the liquid crystal glass 10. The liquid crystal panel packaging box 100 of the invention makes up the height difference between the liquid crystal glass 10 and the PCB 11 by designing different sizes, especially by designing the buffering pieces 4 (4', 4 ") with different heights.

In addition, in the present embodiment, the buffer member 4 is made of an elastic buffer material, so that the liquid crystal panel 1 can be protected from being crushed. In this embodiment, the material of the upper cover 3 may be a foam material having a hardness greater than that of the cushion member 4.

In the present embodiment, a plurality of regulating portions 32 are formed on the inner ceiling wall of the side wall 303. Wherein the inner top wall of the side wall 303 is the inner top wall 300 of the upper lid 3. Each of the adjustment portions 32 is adjacent to the corresponding fitting portion 31 to facilitate mounting of the corresponding cushion member 4. Specifically, the adjusting portion 32 is a rectangular groove having the same width as the width of the fitting portion 31, and the adjusting portion 32 communicates with the accommodating groove 304 and the fitting portion 31, so that the adjusting portion 32 can be easily inserted into and removed from the cushion member 4.

In summary, the liquid crystal panel packaging box 100 of the present invention can adopt the buffering members 4 with different sizes according to the number of the liquid crystal panels 1, the height of the remaining space of the box body 2, and the height difference between the liquid crystal glass 10 and the PCB 11. The buffer member 4 is inserted into the embedding part 31 through the adjusting part 32, and the buffer member 4 is pressed against the liquid crystal panel 10 or the PCB 11, so that the problem of folding of the COF flexible circuit board 12 caused by the height difference between the two sides of the liquid crystal glass 10 and the PCB 11 after the liquid crystal panel 1 is packed in a box is solved, and the problem of material waste caused by a large amount of filling sheets when the packing box is not filled is further solved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
