Embodiment 2

[0045] This embodiment provides a substrate-to-cassette system, and the substrate-to-cassette system includes the turning device described in Embodiment 1. Of course, the substrate cassette alignment device of this embodiment also includes a position alignment device carrying the cassette alignment substrate.

[0046] Since the overturning device in this embodiment can pre-align with the box-matching substrate before the box-matching substrate is aligned, the alignment is more accurate and the alignment time is saved.

[0047] It should be noted that, at present, in the field of display technology, traditional flat-panel display substrates with double-layer substrates are usually manufactured through precise cell alignment processes, such as TFT-LCD liquid crystal display substrates or TFT-LCD liquid crystal display substrates. The liquid crystal cells that are used together to achieve 3D effects require strict control of the pre-alignment accuracy of the two substrates. At p...

Embodiment 3

[0050] This embodiment provides a substrate-to-cassette method, which includes the following steps:

[0051] Step 1. A substrate is sucked by the first suction surface 21 or the second suction surface 22 of the turning device, and the substrate is turned over to the alignment platform facing the alignment device carrying the alignment substrate.

[0052] Step 2: Detect the positional relationship between the substrate adsorbed by the first adsorption surface 21 or the second adsorption surface 22 of the turning device and the alignment substrate carried on the alignment platform, and align the adsorbed substrate with the alignment substrate.

[0053] Step 3: Align the adsorbed substrate with the alignment substrate, detect the positional relationship between the adsorbed substrate and the alignment substrate again, and align the adsorbed substrate with the alignment substrate.

[0054] When the fixed position of the substrate is defective after the box is aligned, step 4 may a...

Description

technical field [0001] The invention belongs to the technical field of box alignment technology, and in particular relates to a turning device, a substrate box alignment system and a substrate box alignment method. Background technique [0002] With the advancement of liquid crystal display technology and the advantages of light weight and small volume of liquid crystal display devices, liquid crystal display devices have been widely used in various electronic products. The liquid crystal display device includes a liquid crystal display panel and a backlight module, wherein the liquid crystal display panel is composed of two substrates and a liquid crystal layer between the two substrates. At this time, the two substrates need to be boxed together to form a liquid crystal box to accommodate liquid crystal molecules. In the process of box alignment, one of the substrates needs to be turned over by a turning device, and then the box is opposite to the other substrate. [000...
