Tray with limiting structure

Abstract

A tray with a limit structure is used for packaging an Open Cell of a liquid crystal screen, and comprises a tray body (10) and a limit assembly (30). A groove (11) for placing the Open Cell is disposed in the tray body (10). The limit assembly (30) is connected to a body bottom plate (12) of a gap between a PCB (23) of the Open Cell and a liquid crystal box (22). The limit assembly can be mounted on the tray body when the limit assembly is needed, or can be taken down when the limit assembly is not needed, thereby expanding the use compatibility of the tray. In addition, a position of a limit block in the limit assembly is adjustable, thereby effectively avoiding pull between the Open Cell and the limit assembly.

Description

technical field [0001] The invention relates to a tray for placing an Open Cell of a liquid crystal screen, in particular to a tray with a position-limiting structure. Background technique [0002] At present, the panel industry has a variety of packaging methods for LCD panels, including blister trays, injection molded boxes, and foamed products; liquid crystal panels have two types: The industry defines them as Cell and Open Cell respectively. Cell is a liquid crystal box formed by sandwiching a liquid crystal seal between two glass substrates. Its appearance is the same as that of ordinary thin glass. Open Cell is equipped with various interfaces on the basis of Cell. , so as to connect an external signal source, etc., but the Open Cell does not include the backlight, frame and other components in the liquid crystal module (LCM, liquid crystal module). [0003] Usually, Open Cell connects more than one PCB board through a flexible sheet. This flexible sheet is called COF...

AI Technical Summary

Problems solved by technology

Open Cells are generally placed flat on the tray, and the positioning device of the tray positions the Open Cell around, because when the Open Cell is subjected to vibration, the PCB board is likely to move with the vibration and pull the COF, resulting in damage to the COF, thus affecting the product quality, and the COF is a flexible sheet, the PCB board is easily brought into two LCD boxes by vibration

In the current Open Cell packaging method, the blister tray is directly formed with columns, such as figure 1 , figure 2 As shown, Open CellA1 has only one COF2, and the tray 4 uses two pillars 5 to block the PCB board 3. This method is only suitable for placing a single tray with a small number of Open Cells. Once the number of Open Cells is large, the pillars 5 will be higher , due to the obstruction of the pillar 5, it is easy to hang the PCB board 3 on the pillar 5 when installing the Open Cell and taking the Open Cell, which will cause the COF2 to be pulled and damaged, which will affect the product quality

The current design of the number of sheets for a single tray is 4 pieces, and this column 5 that has been formed when the tray 4 is produced is not suitable for the commonality of the tray 4. image 3 , if the tray 4 is used to hold the Open Cell B6, the Open Cell B6 has multiple COFs connected to the PCB board 8, and the middle two COF7 will interfere with the two columns 5 of the tray 4, so that the tray 4 cannot be used Install Open Cell B6

Therefore, if you want to install Open Cell B6, you need to re-open a mold for Open Cell B6 to produce the corresponding tray, which causes a waste of mold cost, and this tray is recycled, if not shared, it will cause Waste of packaging resources increases the cost of production
