Lower buffer structure for display panel, package buffer structure and package manufacture method

Abstract

The invention discloses a lower buffer structure for a display panel, a package buffer structure and a package manufacture method. The lower buffer structure comprises a bearing frame body, two first buffer bodies and two second buffer bodies, wherein the bearing frame body comprises a bottom plate and also comprises a first side plate and a second side plate which respectively extend upwards from two opposite sides of the bottom plate; the two first buffer bodies are respectively arranged at the junction of the bearing frame body and the bottom plate and the junction of the second side plate and the bottom plate; the two second buffer bodies are respectively arranged on the inner wall of the first side plate and the inner wall of the second side plate of the bearing frame body and positioned above the first buffer bodies; a line of first vertical groove bodies arranged horizontally at intervals are arranged on the inner side walls of the first buffer bodies; a line of second vertical groove bodies horizontally arranged at intervals are arranged on the inner side walls of the second buffer bodies; the first groove bodies and the second groove bodies correspond one to one up and down; and the hardness of the first buffer bodies is small than that of the second buffer bodies. The invention has low cost, and can provide better buffer protection for the display panel.

Description

technical field [0001] The invention relates to the technical field of article packaging, in particular to a lower buffer structure for a display panel, a packaging buffer structure and a packaging manufacturing method. Background technique [0002] In the prior art, during the storage, transportation, and production processes of the display panel, some necessary packaging cushioning structures are required to be fixed and protected. Especially for large-sized display panels such as liquid crystal display (LCD, Liquid Crystal Display) panels, etc., these display panels are usually stacked at intervals, and such buffer protection is particularly needed to prevent collision damage. [0003] In the prior art, there are the following solutions for the packaging buffer of the display panel: [0004] 1. Refer to figure 1 , the corrugated cardboard 110 is placed in a corrugated box with a cover and a bottom after creasing, die-cutting, bonding, interlocking and assembly, etc., to...

AI Technical Summary

Problems solved by technology

[0004] 1. Refer to figure 1 , the corrugated cardboard 110 is placed in a corrugated box with a cover and a bottom after creasing, die-cutting, bonding, interlocking and assembly, etc., to play the effect of buffering the display panel; the advantage of this technology is that it is more environmentally friendly, and the disadvantage is The reason is that the corrugated cardboard is relatively hard; when it falls, the corner of the display panel is easily deformed where it contacts the corrugated cardboard;

[0005] 2. Refer to figure 2 , the low-density expandable polyethylene (EPE, Expandable Polyethylene) sheet 210 is die-cut and glued and placed in a corrugated box 220 with a cover and a bottom to play the effect of buffering the display panel; the advantage of this technology is that it is relatively It is environmentally friendly and has a good cushioning effect; the disadvantage is that low-density EPE is used as a buffer structure, and the distance between the display panels cannot be too small; because EPE is relatively soft, the distance between the display panels is too small to easily collide with each other;

[0006] 3. Refer to image 3 For the buffering of large-size display panels of 42 inches and above, the corrugated paper or EPE sheet 310 buffer structure of the above-mentioned one or two designs is placed in a paper tray 320 to play a buffering role, and then placed in a covered and bottomless The advantage of this technology is that it is more suitable for the packaging cushioning of large-sized display panels such as 42 inches or above; the cartons used for packaging cushioning have a cover and no bottom, and the display panel is first placed on the lower buffer structure when placing Inside, put a carton on it, and it is just the opposite when it is opened; this is convenient for taking out the display panel, and has the advantages of the above-mentioned one and two designs, but the disadvantage is that the paper tray 320 has a certain thickness, so it occupies a certain space in the width direction; and the paper The price of support 320 is higher than the price of cardboard, and there are disadvantages of the above-mentioned first and second designs at the same time;

[0007] 4. Refer to Figure 4 , made of expandable polystyrene (EPS, Expandable polystyrene) material 410 to directly buffer the display panel in a box shape; the advantage of this technology is that the price of EPS is cheaper than that of EPE and corrugated cardboard, and the disadvantage is that it is not environmentally friendly; especially It is because some countries prohibit the use of EPS, which affects the export of products with this packaging cushioning design; in addition, the cushioning performance of EPS is not as good as that of corrugated cardboard and EPE;

[0008] 5. Refer to Figure 5 , the cushioning structure is made of high-density EPE structure 510 sandwiching low-density EPE structure 520; When placing it, first put the display panel in the lower buffer structure, and then put it on the carton. It is just the opposite when it is opened; this is convenient for the display panel to be taken out, and the cushioning effect is good; the interval between the display panels can be compared to simply using low-density EPE as a buffer. The structural interval is small; the disadvantage is that the combination of high-density buffer structure 510 and low-density buffer structure 520 is too complicated, adding too many manufacturing processes and consuming too much labor cost; moreover, the price of high-density EPE structure 510 is relatively high, and the entire buffer The price of the structure is also relatively high
