in step S44, the fourth transfer module 34 returns to the initial position and is reset.

In this embodiment, in order to guarantee the efficiency of laminating, after the frock board flows first buffer memory station platform 22, judge according to the state of laminating station, when first laminating station platform 23 has the blank signal, directly put the board and give first laminating station platform 23, when first laminating station platform 23 has the board and second laminating station platform 24 does not have the board, the frock board of first laminating station platform 23 can be put the board and give second laminating station platform 24 at the jack-up in-process.

After the glass loading is started, the glass is placed manually, the glass is firstly waited to flow into a photographing position, the glass is positioned by the second monitoring camera 52, photographing counting can be carried out if photographing fails, after the photographing fails for multiple times, the system can give an alarm to wait for manual processing, and a photographing link is entered again after the manual processing is finished. When the photographing is successful, the material taking distribution is started, the system is designed to take materials for the third transferring component 33 preferentially, and when the third transferring component 33 does not take materials, the system can take materials for the second transferring component 32; the first laminating station 23 and the second laminating station 24 are substantially identical in flow, and the first laminating station 23 is illustrated here.

After the laminating starts, the initial position can be fixed a position to the climbing mechanism of third monitoring camera 53 and first laminating station platform 23, then can judge whether have the frock board on the station, if do not have the frock board then send empty board signal and wait for first buffer memory station to put the board into, if there is the frock board then open the logical judgement before the laminating starts: a total of three cases are included: when the tooling plate is an empty plate, the blank is directly released, and a side-by-side positioning completion signal is sent to the second laminating station table 24; when the tooling plate has a back plate but the second laminating station table 24 has a main plate signal, preferentially placing the plate to simultaneously set a machining signal for the second laminating station table 24; when the tooling plate has a back plate and the second laminating station 24 does not have a plate signal, the laminating action is started.

When the glass transfer assembly 32 is selected to be released, the system sends a glass shooting signal to the UVW platform of the second transfer assembly 32 again to be positioned, meanwhile, the light source plates are withdrawn, the glass shooting signal is sent to the second transfer assembly 32 again, the second transfer assembly 32 is waited to be released again, if the glass shooting is successful, the system sends a deviation correcting parameter to the UVW platform of the second transfer assembly 32 to be positioned, and finally the jacking mechanism of the first bonding station platform 23 descends and sends a gluing command to the second transfer assembly 32, and finally the second transfer assembly 32 is reset after the second transfer assembly 32 is finished to be bonded, and the jacking mechanism of the first bonding station 23 simultaneously sends a gluing release signal to the backboard to be sent to be subjected to photographing.

After the product that the laminating was accomplished flows into pressurize station platform 26, the pressurize head can switch to the moment mode, and when the pressure sensor of the climbing mechanism below of pressurize station platform 26 reached the settlement pressure, the pressurize head can stop pushing down and the pressurize lasts 5 seconds simultaneously, and the pressure head lifts up and the climbing mechanism of pressurize station platform 26 resets after reaching the settlement time, then the pressure head carries out the initial point and returns and releases the frock board simultaneously.

The invention has the beneficial effects that:

1. the automatic laminating system is adopted for laminating, compared with manual laminating, the laminating stability and precision are improved, the product quality is guaranteed, and the multi-station combination and pressure maintaining working mode is adopted in the laminating line body 20, so that the production efficiency is improved;

2. on the premise of not changing the original belt line 10 mode, the whole process of display attaching is shifted out of the line, and meanwhile, the assembly line operation mode is ingeniously utilized, so that the running efficiency, the beat and the reproducibility of the system are guaranteed on the premise of improving the process quality.

The artifical drawback that the display laminating exists and the problem that the automatic laminating exists of realization was carried out on traditional belt line 10 to this embodiment is main, fully combine display laminating technology, outside moving belt line 10 with the whole laminating technology of display, the automatic operation station has been designed to the operational mode of reference automatic cylinder line and returning the board lifting machine simultaneously, through transferring module 30 unloading, the laminating of dual transfer subassembly simultaneously, jacking operation and automatic pressurize operation, the automatic laminating of high efficiency of display has not only been realized, combine camera module 50 to rectify simultaneously, UVW platform assistance-localization real-time and pressurize pressure detection have realized the high accuracy laminating and the pressurize of display, not only replaced manual work through automatic laminating, and the quality and the production efficiency of product have been improved.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
