Problems solved by technology

However, because the traditional packaging method cannot bear the external pressure well during transportation, it may deform the multi-layered LCD panel, which not only affects the use effect, but also brings unnecessary losses to the enterprise
The main reason is that the convex structure and rib wall of the traditional injection-molded packaging box are relatively thick. During the injection molding of the packaging box, the convex structure is concave due to uneven shrinkage. The depression of the raised structure is becoming more and more serious. The existence of the concave convex structure causes the injection molded packaging box to press the LCD panel in the box when stacked, which affects the quality of the LCD panel. At the same time, the injection molded packaging box with a concave convex structure is not conducive to Recycling increases packaging costs

Embodiment 1

[0025] refer to figure 2 , the protruding structure 210 is composed of an upper surface 211 and a lower surface 212. In this embodiment, the upper surface 211 and the lower surface 212 are both arc-shaped surfaces convex upward. When carrying the liquid crystal panel, the liquid crystal panel first contacts the upper surface 211 of the raised structure 210, and the arc-shaped raised structure 210 generates yield stress to support the liquid crystal panel. stacked so that the gravity of the liquid crystal panel is greater than the yield stress of the protruding structure 210, when the liquid crystal panel is placed in the box body 10, the effect of the protruding structure 210 protruding into the box body 10 is offset, and the protruding structure 210 is flat The panel does not affect the flatness of the liquid crystal panel placed in the box 10 . When the liquid crystal panel is removed from the box body 10 , the yield strength of the raised structure 210 ensures that the ra...

Embodiment 2

[0027] refer to image 3 , Figure 4 The upper surface 211 of the protruding structure 210 is an upwardly convex arc surface or a plane, the lower surface 212 is a plane, and several reinforcing ribs 230 are arranged on the outer side of the lower surface 212 . In this embodiment, the upper surface of the raised structure 210 is a plane. The rib 230 includes a rigid end 231 and a flexible end 232. The rigid end 231 is located on both sides of the rib 230, and the flexible end 232 is located in the middle of the rib 230. The height of the rigid end 231 is greater than that of the flexible end 232 , so that the outer edge of the rib 230 is a circular arc concave along the outside of the box body 10 toward the inside of the box body 10 , so that the protruding structure 210 is in the shape of a concave lens. Since the height of the rigid end 231 is greater than the height of the flexible end 232, the surrounding strength of the bottom panel 200 of the box body 10 is greater than...

Embodiment 3

[0029] refer to Figure 5 In this embodiment, the upper surface 211 of the protruding structure 210 is an upwardly convex arc surface, and the lower surface 212 is a plane. Each reinforcing rib 230 is provided on the lower surface 212 and is located outside the bottom panel 200 . Since the upper surface 211 of the protruding structure 210 is an upwardly convex arc surface, and the lower surface is connected with a concave reinforcing rib 230, it has a double suppression effect on the concave problem at the bottom of the box body 10, so that the box body 10 has a more Good yield strength has a better technical effect on preventing the bottom of the packaging box from sinking, and is suitable for packaging boxes carrying large-size LCD panels.

[0030] To sum up, the injection molding packaging box for liquid crystal panels provided by the present invention has a simple structure, increases the bending strength of the injection molding packaging box, solves the problem of the co...

Abstract

An injection-moulded packaging box for liquid crystal panels, comprising a box body (10). The box body (10) consists of side wall plates (100) and a bottom surface plate (200). The bottom surface plate (200) is provided with a protrusion structure (210) which protrudes towards the inside of the box body. The injection-moulded packaging box for liquid crystal panels increases the resistance to bending of the injection-moulded packaging box, solves the problem of the bottom of the injection-moulded packaging box bulging downwardly, avoids the influence on the quality of the liquid crystal display panels of mutually overlaying the injection-moulded packaging boxes, increases the number of times for which the injection-moulded packaging boxes can be recovered, and reduces the packaging cost.

Description

technical field [0001] The invention relates to the field of manufacturing and packaging of liquid crystal panels, in particular to an injection molding packaging box for liquid crystal panels. Background technique [0002] In the electronics industry, the production and assembly of electronic products requires complex supply chain support. Usually, the components of electronic products are mass-produced and manufactured in different places, and after transportation, they are uniformly delivered to the assembly factory for assembly. In the field of liquid crystal display equipment, the liquid crystal panel is the core component of the liquid crystal display equipment, and the reliability of the packaging needs to be considered during transportation. However, because the traditional packaging method cannot bear the external pressure well during transportation, it may deform the multi-layered liquid crystal panel, which not only affects the use effect, but also brings unneces...
