[0002] The LCD screen is mainly composed of backlight and LCD panel. The LCD panel (Open cell) is just a component of the LCD screen. The quality of an LCD display depends on its panel. The quality of the panel directly affects the viewing effect of the picture. In addition, the LCD TV panel accounts for more than half of the cost of the whole machine, which is the main factor affecting the cost of LCD TV.

[0003] At present, a back panel needs to be attached to the side of the LCD panel during the processing. In order to improve the use effect of the product, the liquid crystal surface of the LCD panel after bonding needs to be inspected to ensure that the processed LCD panel meets the expected requirements. At present, most of the existing inspection methods require multiple inspectors to lift the LCD panel after the back panel is attached and flip it to a specified angle for manual inspection. Obviously, the above inspection method is not only time-consuming and labor-intensive, but also has high work intensity and low inspection efficiency. In addition, when the LCD panel is lifted, it will inevitably cause damage to the LCD panel, which urgently needs to be solved. Utility Model Content
