Display panel packaging box with cushioning function

Abstract

The display panel packaging box with cushioning function of the present invention includes a bottom plate and four side walls, the four side walls are vertically connected to the bottom plate, and the bottom plate and the four side walls jointly enclose an accommodating space , the accommodating space is used to place the display panel, and the display panel packaging box with buffer function also includes a buffer device and a locking device; before loading the display panel, the buffer device is compressed by the locking device , the compressed buffer device is placed in the packing box, and will not interfere with the packing of the display panel. After the buffer device is loosened, self-adaptive adjustment can be realized, and the display panel can be closely attached to stabilize the panel. effect.

Description

technical field [0001] The invention relates to the packaging field of display panels, in particular to a display panel packaging box with a buffer function. Background technique [0002] With the progress and development of science and technology, various display terminals are more and more integrated into our lives, and the panel industry has also ushered in a bonus period, and a large number of panels are produced. The liquid crystal display panel is connected to a printed circuit board (Printed Circuit Board, PCB) through a Chip On Flex (or, Chip On Film, COF) to realize signal transmission. [0003] The semi-finished display panels and finished display panels produced on each production line are transferred through packing boxes. During the transfer operation, there will be gaps between the packing boxes and the display panels, and the original packing boxes will be provided with fixed retaining walls or blocks around them. Reduce the amount of active displacement of t...

Problems solved by technology

However, due to the inevitable precision error in the manufacturing process, there will still be a certain gap after the packaging box is loaded into the display panel, so this packaging box is not suitable for display panels with high resolution and ultra-narrow borders, because the high The resolution and ultra-narrow bezel chip-on-chip are very dense. In the case of a long printed circuit board, if the displacement of the display panel cannot be stably limited, it is easy to cause damage to the liquid crystal glass or the connection of the chip-on-chip during transportation. Tearing causes poor display

[0004] In addition, in the prior art, in order to allow the stopper to closely fit the display panel to alleviate the impact force, the stopper can also be designed as an independent component, and the stopper can be placed in the packing box before loading the display panel, This method has the disadvantage of inconvenient installation of the display panel

Of course, it is also possible to put a stopper after installing the display panel, such as inserting the stopper into the gap between the panel and the packing box, but this method is time-consuming and laborious, and the panel will be accidentally damaged during the operation, and the stopper will be damaged during transportation. The position also changes, making it difficult to provide a protective panel anymore
