[0033] Example 1

[0034] The present invention provides an automatic laminating device for ink filling, combined with Figures 1 to 10As shown, in this embodiment, it includes a workbench 1, and also includes a plurality of glass substrates 2, a loading part 3, a bonding work part 4 and a receiving part 5, all of which are arranged on the workbench 1.

[0035] It also includes a glass handling articulated robot 6 which can be rotatably arranged on the workbench 1 in the circumferential direction. The glass handling articulated robot 6 is arranged between the glass sheet conveying transfer table 32 located on the left side and the transfer area on the front side of the vacuum laminating machine 40; the vacuum laminating machine 40 is equipped with a dry clean room 7.

[0036] It should be noted that the process of automated production of the present invention is as follows: Figures 1 to 8 As shown, first, the glass substrate 2 to be processed needs to be manually placed on the upper substrate loading machine 30, and then the glass substrate 2 is conveyed to the upper substrate visual glue dispenser 31 by a conveyor belt for visual glue dispense. After the upper substrate visual glue dispenser 31 completes the glue dispense, the glass substrate 2 after the glue dispense is transported to the dry clean room 7 by the glass sheet conveying transfer table 32, and the upper substrate is transported to the upper platform by the glass handling joint robot 6. At this time, the upper substrate is in a waiting stage; at the same time, the lower substrate is fed to the loading machine 30, and the lower substrate is transported to the dry clean room 7 by the conveyor belt. Then, the glass handling joint robot 6 transports the lower substrate to the lower platform, and then the lower substrate is inked. After the ink dispense of the lower substrate is completed, the glass substrate is transported to the pressure in the vacuum bonding machine 40 in combination with the glass handling joint robot 6. The cavity is pressed together, and the dry clean room is vacuumed for 30 seconds to the standard value, and then the upper and lower substrates are used to realize visual alignment and pressing of the glass substrate 2, and then UV pre-curing is performed. After curing, the upper and lower platforms are separated, and the pressure of the pressing cavity in the vacuum laminating machine 40 is released to realize opening the vacuum cavity, and then the glass handling joint robot 6 transports the processed glass substrate 2 to the receiving machine, and finally the glass substrate product is completed through the UV curing process; in this way, the entire glass substrate ink filling and laminating process, from loading in the feeder to the finished product, does not require manual operation; and the glass handling joint robot 6 is set to be able to reciprocate and transport the glass substrate 2, so that the process operation is more flexible; in addition, a dry clean room is equipped to prevent frost and condensation in a low temperature environment.

[0037] The working rhythm involved in the above working principle is shown in Figure 3 shown.

[0038] Please combine Figures 1 to 5 As shown, in this embodiment, the loading machine 30 includes a lifting mechanism 300 with multiple driving wheels (not shown in the figure, all hereinafter) and a grabbing fixture (not shown in the figure, all hereinafter), and the multiple driving wheels of the lifting mechanism 300 are respectively in contact with the glass substrate 2;

[0039] When the glass substrate 2 falls onto the driving wheel, the driving wheel drives the glass substrate 2 to move forward to a fixed position, and then the grabbing fixture grabs the glass substrate 2 and places it on a work station. At this time, the lifting mechanism 300 moves down one grid, and the above actions are repeated.

[0040] Please combine Figure 1 and Figure 5 As shown, in this embodiment, the upper substrate visual glue dispenser 31 is an online gantry-type UV glue dispenser, which is started after the glass substrate 2 is placed and the lifting mechanism 300 is adopted;

[0041] At this time, the four sides of the glass substrate 2 are positioned, and the glue dispensing starts by visually grabbing the target of the online gantry-type UV glue dispensing machine, and the glue dispensing track of the online gantry-type UV glue dispensing machine can be imported into the DXF document for recognition.

The controller of the vacuum laminating machine 40 can import a DXF trajectory file to identify the trajectory, and the cantilever ink dotting machine is placed as a whole on the marble platform bottom plate of the workbench. In this way, through the above design, its parallelism can be guaranteed.
