Description

Technical Field

[0001] The utility model relates to the technical field of tray devices, in particular to a liquid crystal panel detection tray device. Background Art

[0002] With the widespread use of liquid crystal displays, there is a great demand for the maintenance and inspection of LCD panels. However, LCD panels generally have a large surface area and cannot be squeezed or stained with dust, so it is difficult to fix and inspect the LCD panels. In the existing technology, the fixation of LCD panels is generally performed by negative pressure adsorption, which can fix the LCD panels well without damaging them. Such devices include the Chinese patented liquid crystal panel detection tray device with application number 202021871810.1, but this patent has a disadvantage when used, that is, it cannot be adjusted and can only adapt to fixed-size LCD panels for fixation, resulting in a small scope of application for adsorption and fixation. Therefore, an improved liquid crystal panel detection tray device is needed to address this problem. Utility Model Content
