[0039] As described in the background art, in the processing process of a display panel, before detecting the surface of the display panel, it is often necessary to adsorb the display panel and then transport the display panel to the detection station. The prior art usually uses an adsorption jig to adsorb the display panel. Specifically, by arranging a plurality of adsorption components on the carrier table of the adsorption jig, the vacuum nozzles on the adsorption components are used to adsorb the display panel. However, arranging a plurality of adsorption components will increase the production cost and result in poor adsorption effect; moreover, directly placing the display panel on a plurality of adsorption components also has the problem of unstable installation process.

[0040] Based on this, please refer to Figures 1-4 , an embodiment of the present invention provides a display panel adsorption jig 100, which can effectively improve the above-mentioned technical problems, that is, it can reduce the production cost, improve the adsorption effect, and enhance the stability during the installation process of the display panel.

[0041] It should be noted that the first direction mentioned in the following content is the Figures 1-4 X direction shown in Figures 1-4 , the second direction is the Figures 1-4 Y direction shown in

[0042] Figure 1 Figure 2 and Figure 1 , Figure 2 is a schematic structural diagram of the display panel adsorption jig 100 provided in this embodiment, Figure 2 is a partial structural diagram of the display panel adsorption jig 100 provided in this embodiment. Combining Figure 1 and Figure 2 , the display panel adsorption jig 100 includes a carrier platform 10, an adsorption plate 20, a lifting device 30, and a plurality of top column structures 40. The carrier platform 10 includes a platform body 11 and a plurality of support columns 12 arranged on the platform body 11; the adsorption plate 20 is connected to the plurality of support columns 12 and is spaced from the platform body 11, and the adsorption plate 20 is provided with a plurality of through holes 21; the lifting device 30 is arranged on the platform body 11, and the plurality of top column structures 40 are all arranged on the lifting device 30 and correspond to the plurality of through holes 21 one by one; wherein, the lifting device 30 is used to drive the plurality of top column structures 40 to lift, so that the plurality of top column structures 40 respectively extend out of or retract into the plurality of through holes 21.

[0043] During the adsorption and installation process of the display panel, the multiple top column structures 40 are first driven to rise by the lifting device 30, and extend from the multiple through holes 21 of the adsorption plate 20 respectively, and then the robot is operated to place the display panel on the multiple top column structures 40; then the robot is pulled out, and then the multiple top column structures 40 are driven to descend by the lifting device 30, and retract from the multiple through holes 21 respectively. During this process, the display panel will gradually follow the descent and finally fall onto the adsorption plate 20, and then the display panel will be adsorbed by the adsorption effect of the adsorption plate 20.

[0044] It is easy to understand that by setting up the adsorption plate 20 to adsorb the display panel, there is no need to set up more adsorption components, which can reduce production costs and improve the adsorption effect; and through the cooperation between the lifting device 30, the top column structure 40 and the through hole 21 opened in the adsorption plate 20, the stability of the display panel during installation can also be improved.

[0045] Furthermore, the device includes a driver 31, a synchronous lifter 32 and a lifting plate 33.

[0046] That is to say, the driver 31 can drive the synchronous lifter 32 to realize lifting movement. By setting the lifting plate 33 on the screw lifting nut 320 of the synchronous lifter 32, the screw lifting nut 320 can drive the multiple top column structures 40 on the lifting plate 33 to perform lifting movement synchronously during the lifting process.

[0047] It should be noted that, in this embodiment, the driver 31 is specifically a servo motor, which is connected to the synchronous lifter 32 through the servo motor, and can accurately control the lifting speed of the synchronous lifter 32, further improving the stability of the display panel during installation, and preventing the display panel from cracking during the lifting process. Of course, in some other embodiments, the driver 31 can also be other driving devices such as a stepper motor or a torque motor.

[0048] Specifically, please refer to Figure 3 and Figure 4 , Figure 3 A partial structural diagram of the lifting device 30 provided in this embodiment from a first perspective, Figure 4 A partial structural diagram of the lifting device 30 provided in this embodiment from a second perspective, combined with Figures 2-4, the synchronous lifter 32 includes a first lifter 321, a first transmission shaft 322, a second lifter 323, a second transmission shaft 324, a commutator 325, a third transmission shaft 326, a third lifter 327, a fourth transmission shaft 328, and a fourth lifter 329 that are sequentially connected in transmission.

[0049] It can be understood that the driver 31 drives the commutator 325, and transmits the power to the lifters through the transmission shafts, which is specifically achieved by the synchronous transmission cooperation between the first transmission shaft 322, the second transmission shaft 324, the third transmission shaft 326, the fourth transmission shaft 328 and the first lifter 321, the second lifter 323, the third lifter 327, and the fourth lifter 329, so that the screw rod lifting nuts 320 on each lifter can move up or down synchronously.

[0050] Furthermore, the lifting plate 33 includes a first lifting plate 331 and a second lifting plate 332. The first lifting plate 331 and the second lifting plate 332 are arranged at intervals, and the first lifting plate 331 is simultaneously connected to the screw rod lifting nuts 320 of the first lifter 321 and the fourth lifter 329, and the second lifting plate 332 is simultaneously connected to the screw rod lifting nuts 320 of the second lifter 323 and the third lifter 327; wherein, at least one top column structure 40 is provided on both the first lifting plate 331 and the second lifting plate 332.

The two ends of the reinforcing plate 333 are respectively connected to the first lifting plate 331 and the second lifting plate 332, and at least one top column structure 40 is provided on the reinforcing plate 333.

[0052] It should be noted that in this embodiment, only the reinforcing plate 333 is provided with the top column structure 40. It is easy to understand that the first lifting plate 331 and the second lifting plate 332 are driven by the screw rod lifting nut 320 to lift and lower, so that the top column structure 40 on the reinforcing plate 333 can follow the lifting and lowering movement. Of course, in other embodiments, the reinforcing plate 333 may not be provided. At this time, the top column structure 40 is provided on the first lifting plate 331 and the second lifting plate 332; in addition, in some embodiments, the top column structure 40 may also be provided on the first lifting plate 331, the second lifting plate 332, and the reinforcing plate 333; the specific setting position of the top column structure 40 needs to be determined according to the actual design requirements of the adsorption jig.

[0053] The first lifting plate 331 and the second lifting plate 332 are arranged at intervals along the first direction. In order to further improve the support effect on the display panel and enhance the stability during installation, the number of reinforcing plates 333 is set to be multiple, and the multiple reinforcing plates 333 are arranged at intervals along the second direction, and both ends of the multiple reinforcing plates 333 are respectively connected to the first lifting plate 331 and the second lifting plate 332; wherein, the first direction and the second direction form an angle.

[0055] It should be noted that in this embodiment, the number of the reinforcing plates 333 is specifically six, and each reinforcing plate 333 is provided with five top column structures 40; of course, in other embodiments, the number of the reinforcing plates 333 and the top column structures 40 is not limited to this, and the specific numbers of both need to be determined according to the actual design requirements.

[0056] Please continue to combine Figures 2-4 . In order to facilitate the maintenance and troubleshooting of the elevator, the first elevator 321, the second elevator 323, the third elevator 327, and the fourth elevator 329 are respectively arranged close to the four peripheral edges of the platform body 11.

[0057] After the display panel falls into the adsorption plate 20, in order to better clamp and position the display panel, combining Figure 1 and Figure 2 , in this embodiment, the display panel adsorption jig 100 further includes a plurality of side push mechanisms 50, and the plurality of side push mechanisms 50 are all arranged on the platform body 11 and are used for positioning and clamping the display panel adsorbed on the adsorption plate 20.

[0058] Specifically, a plurality of side push channels 22 are further formed in the adsorption plate 20. The plurality of side push channels 22 correspond to the plurality of side push mechanisms 50 one by one, and the side push columns 51 of the plurality of side push mechanisms 50 are respectively movably disposed in the plurality of side push channels 22.

[0059] It should be noted that the specific positions of the plurality of side push mechanisms 50 on the platform body 11 need to be determined according to actual positioning and clamping requirements. For example, in this embodiment, side push mechanisms 50 are disposed around the platform body 11, capable of simultaneously clamping and positioning the display panel in the X direction and the Y direction. Specifically, the number of side push mechanisms 50 is eight. The eight side push mechanisms 50 are grouped in pairs and are respectively disposed on the four sides of the platform body 11.

[0060] Furthermore, in order to ensure the overall flatness of the carrier platform 10, the display panel adsorption jig 100 further includes a plurality of flatness adjusting members 60. At least one flatness adjusting member 60 is provided on each support column 12, and the adsorption plate 20 is simultaneously disposed on the plurality of flatness adjusting members 60.

[0061] It should be noted that the overall flatness of the adsorption plate 20 can be adjusted by the flatness adjusting member 60. During actual operation, it can be used in conjunction with a flatness measuring instrument, and adjusted while measuring with the flatness measuring instrument.

[0062] In addition, it should also be noted that the specific positions of the plurality of support columns 12 on the platform body 11 need to be determined according to the design requirements of the actual adsorption jig; and the specific number of flatness adjusting members 60 provided on each support column 12 also needs to be determined in combination with the specific structure of the actual adsorption plate 20 and the specific positions of the support columns 12.

During the adsorption and installation process of the display panel, first, the lifting device 30 is used to drive the plurality of ejector pin structures 40 to rise and extend out of the plurality of through holes 21 of the adsorption plate 20 respectively, and then the manipulator is operated to place the display panel on the plurality of ejector pin structures 40; then the manipulator is withdrawn, and then the lifting device 30 is used to drive the plurality of ejector pin structures 40 to descend and retract into the plurality of through holes 21 respectively.
