[0079] As described above, the LCD loading device 2 is provided with two shorter transfer units, namely the first LCD transfer unit 23a and the second LCD transfer unit 23b, on the feeding path between the LCD loading unit 21 and the receiving end of the pressing and laminating device 5 (below the first gantry 51a). In some other embodiments, only one transfer unit may be provided, for example, the second LCD transfer unit 22b and the second LCD transfer unit 23b are cancelled, and then the first LCD transfer unit 23a is extended to the bottom of the first gantry 51a. In this embodiment, two transfer units are provided, which can improve production efficiency compared with the scheme of only providing one transfer unit. Specifically, since the back-end process requires a relatively long time for pre-pressing and holding pressure, when the second LCD transfer unit 23b transports the liquid crystal panel to the bottom of the first gantry 51a for waiting, the front-end first LCD transfer unit 23a can be released at this time, and the liquid crystal panel fed by the LCD loading unit 21 can be returned to be received. The standby time of the front-end mechanism is relatively short, which improves efficiency. If only one transfer unit is set, for example, the extended first LCD transfer unit 23a, it is necessary to wait for the first LCD transfer unit 23a to send the liquid crystal panel into the pressure bonding device 5 before returning to receive the liquid crystal panel loaded by the LCD loading unit 21, and then transfer it to the bottom of the first gantry 51a of the pressure bonding device 5. The standby time of the front-end mechanism is relatively long.

[0080] In this embodiment, refer to Figures 1 to 3 and Figure 15 , the unloading device 6 includes an unloading manipulator 61, a sixth linear drive die 62 is connected to the side of the second gantry 53a away from the pre-pressing manipulator assembly 51, the sixth linear drive die 62 extends along the second direction, and the unloading manipulator 61 is movably connected to the sixth linear drive die 62. Further, the unloading device 6 also includes an AOI inspection mechanism 63, a qualified product output mechanism 64, and a non-qualified product output mechanism 65 arranged below the moving line of the unloading manipulator 61. After the pressing platform 52b in the pressing and laminating device 5 moves the assembled product to the unloading unit 6, the unloading manipulator 61 grabs the assembled product and first transfers it to the AOI inspection mechanism 63 for inspection to confirm the quality of the assembly: if it is a good product, the assembled product is sent to the qualified product output mechanism 64 for output; if it is a defective product, the assembled product is sent to the non-qualified product output mechanism 65 for output.
