[0060] Firstly, OCA is transported from the upstream equipment to the OCA feeding device 13, the OCA feeding device 16 moves the OCA from the OCA feeding device 13 to the third transfer platform 18, the OCA taking mechanism 115 moves the OCA on the third transfer platform 18 to the vacuum plate platform 142 of the roller laminating platform 14, the OCA film tearing mechanism 116 tears off the film on the OCA by grabbing the easy-to-tear sticker provided by the first film tearing easy-to-tear sticker feeding device 32 on the side of the OCA film tearing mechanism 116, at the same time, CG is transported from the upstream equipment to the CG rotating correction platform 121, the position of the CG is rotated and corrected, the CG sticking head 113 sucks the CG, the OCA with the film removed is moved to the CG sticking head 113 by the vacuum plate platform 142, the CG sticking head 113 bonds the CG downward with the upper surface of the OCA, then the semi-finished product of the CG and the OCA bonded together by the CG sticking head 113 is placed on the second transfer platform 17, the vacuum plate platform 142 moves back to the side of the OCA feeding device 13, and waits for the next feeding; the OCA taking mechanism 115 feeds the two roller laminating platforms 14 alternately, the OCA film tearing mechanism 116 tears off the film on the OCA on the two roller laminating platforms 14 alternately, the CG sticking head 113 drives the CG to bond with the OCA on the two roller laminating platforms 14 alternately, so that the two roller laminating platforms 14 work alternately, saving working time; the film tearing and sucking mechanism 114 sucks the semi-finished product of the CG and the OCA bonded together and moves it to the heavy film tearing device 15, the heavy film tearing device 15 grabs the easy-to-tear sticker provided by the second film tearing easy-to-tear sticker feeding device 19 on the side of the heavy film tearing device 15, bonds the easy-to-tear sticker with the lower film of the OCA, tears off the lower film of the OCA by pulling the easy-to-tear sticker, and then places the semi-finished product with the lower film removed on the fourth transfer platform 152;Meanwhile, the LCD feeding device 22 moves the LCD to the LCD loading device 26, and the LCD loading device 26 moves the LCD to the rotating disc 211. The rotating disc 211 rotates 90° each time and stops for a short time. The LCD rotates to the LCD film tearing device 23, the hard-to-hard lamination device 24, the empty position, and finally returns to the initial position. When the LCD rotates to the LCD film tearing device 23, the LCD film tearing device 23 tears the film on the LCD by using the easy-to-tear sticker provided by the first film tearing easy-to-tear sticker feeding mechanism 32 on the side of the LCD film tearing device 23. When the LCD rotates to the hard-to-hard lamination device 24, the hard-to-hard suction plate mechanism 242 sucks the semi-finished product on which the CG and the OCA are bonded together on the fourth intermediate platform 152, and places it above the LCD on which the film is torn to bond the semi-finished product to obtain the semi-finished product on which the CG, the OCA and the LCD are bonded together. The semi-finished product returns to the initial position with the rotating disc 211. The semi-finished product on which the CG and the OCA are bonded with the LCD after the hard-to-hard lamination is moved to the two lower cavities 252 by the semi-finished product carrying device 27 in turn. The upper cavity 251 moves between the two lower cavities 252. The lower cavity 252 on which the semi-finished product is loaded moves downward to perform the vacuumizing lamination and pressure defoaming operation. Finally, the finished product is moved from the lower cavity 252 to the finished product unloading line 28 by the finished product unloading device 29, and the finished product is moved to the downstream process by the finished product unloading line 28.
