Ultra-high-definition large-size display screens will become a trend in the future, and transportation of the super-sized display screens will become a problem. For the transportation of super-sized display panels, it is necessary to use super-large packaging devices. At present, the super-large packaging devices in the prior art mostly adopt a manufacturing method of splicing and forming. For example, two packaging boxes are fixed together by section steel and screws. The forming process is complex and time-consuming, the appearance is bulky and unsightly. In addition, the final packaging device is formed by splicing two parts, the size of the seam is difficult to control, and the sealing performance is poor.
In view of this, embodiments of the present disclosure provide a packaging device, as shown in
The bottom plate 1 completely wraps the supporting piece 3. An extending direction of the supporting piece 3 is roughly parallel to the surface of the bottom plate 1.
A material of the supporting piece 3 is different from that of the bottom plate 1, and a strength of the supporting piece 3 is greater than that of the bottom plate 1.
In the packaging device provided by the embodiments of the present disclosure, the supporting piece is placed inside the bottom plate, and the bottom plate completely wraps the supporting piece, so that when the packaging device is manufactured by a mold, the supporting piece may be placed in the mold firstly, then a material used for manufacturing the packaging device is filled, and thus the packaging device and the supporting piece may be manufactured at one time. The process flow omits the steps of manually assembling the supporting piece and the packaging device, which greatly saves the manufacturing time and the manufacturing cost. In addition, since the packaging device and the supporting piece are manufactured at one time, there is no seam, and the sealing performance is good. The material used for manufacturing the packaging device completely wraps the supporting piece, so that the supporting piece cannot be seen from the appearance, and the appearance is relatively smooth and beautiful. The supporting piece is generally made of a metal material, the supporting piece of the embodiments of the present disclosure is located in the bottom plate, which may not be corroded.
The packaging device provided by the embodiments of the present disclosure may be used for packaging and transporting various types of display panels, such as a Liquid Crystal Display (LCD) panel and an Organic Light-Emitting Diode (OLED) display panel. Of course, the packaging device provided by the embodiments of the present disclosure may also be used for transporting other products. Taking the LCD panel as an example, the LCD panel is placed in the containing cavity formed by joint enclosure of the bottom plate and the annular side plate, movement of the placed LCD panel is prevented through the containing cavity, so that the LCD panel is limited, and the poor quality phenomena such as panel rupture and crack during transportation are avoided.
