[0111] The vacuum bonding of large-size CG and LCD curved multi-screens of the present invention comprises the following steps:

[0112] Step S1, the LCD loading end performs the LCD loading operation. Meanwhile, the CG loading end performs the CG loading operation.

[0113] Step S2, the LCD film tearing mechanism 100 automatically tears the film of the LCD, and a worker tears the film of the CG. The CG manual feeding and flipping table 820 flips the CG so that the bonding surface faces downwards, and the CG moves to the USC cleaning mechanism 400 for cleaning.

[0114] After the LCD film tearing is completed in Step S3, the LCD is loaded onto the alignment platform 200 by the LCD rotating loading pallet 720. The cleaned CG is moved to the CG rotating loading suction claw 800 by the CG transfer platform 300, and is grabbed by the CG rotating loading suction claw 800 and transferred to the CG transfer platform 810, and then transferred to the upper cavity 600 by the CG transfer platform 810.
