Description

Technical Field

[0001] The present invention relates to the technical field of panel packaging devices, and in particular to a rigid display panel packaging device and a packaging method thereof. Background Art

[0002] OLED, also known as organic electro-laser display or organic light-emitting semiconductor, is a current-type organic light-emitting device. Its main principle is that under the influence of an electric field, holes generated at the anode and electrons generated at the cathode migrate, injecting into the hole transport layer and electron transport layer, respectively, and then migrating to the light-emitting layer. When the two meet in the light-emitting layer, energy excitons are generated, which excite the light-emitting molecules and ultimately produce visible light. The luminous intensity is proportional to the injected current, making it suitable for a wide range of applications.

[0003] At present, compared with LCD, the existing OLED rigid display panel has the advantages of being lighter, thinner, brighter, lower power consumption, faster response, higher clarity, better flexibility and higher luminous efficiency, which can meet consumers' new demands for display technology. In the production process of OLED rigid display panels, the packaging technology is usually laser welding packaging technology, which can fully guarantee the structural strength of the panel assembly and ensure the service life. However, in the actual packaging process, there is a lack of convenient and targeted centering and pressing pre-treatment technology between the panel assemblies in the OLED rigid display panel. In the subsequent vacuum lamination process, there is a certain probability of irreversible structural combination displacement deviation, which will adversely affect the processing quality of the overall process.

[0023] See also Figure 3 、 Figure 6 The pressing platform 4 is mounted on the top of the base 1 through a bearing sleeve and is coplanar with the top of the base 1.

If the difference is within the standard range, it means that the appearance dimensions of the first panel component 2 and the second panel component 3 when stacked are qualified. On the contrary, if the difference is not within the standard range, it means that the appearance dimensions of the first panel component 2 and the second panel component 3 when stacked are qualified, and the first panel component 2 and the second panel component 3 need to be repaired.

[0029] The packaging method comprises the following steps: The first step is to prepare the ingredients; The first panel component 2 and the second panel component 3 are formed respectively through existing front-end processes, including IGZO technology, evaporation and etching, atomic layer deposition, etc.; The second step is preliminary pressing; The first panel component 2 and the second panel component 3 are stacked up and placed on the top surface of the pressing platform 4. Then, the first arc-surface electromagnet 63 is turned on, so that the magnetic surface of the first arc-surface electromagnet 63 is magnetically connected with the surface of the linkage shaft 52. Subsequently, the first brake servo motor 51 is started, and the output end of the first brake servo motor 51 is driven by the linkage shaft 52 to engage the first gear ring 61 inside the transmission component 6, and then the first gear ring 61 is used to engage the second gear ring 62.

Next, the second brake servo motor 10 is started, and the output end of the second brake servo motor 10 drives the lead screw 11, which then engages the transmission nut 12 on the surface of the lead screw 11. By utilizing the lead screw transmission principle, the nut 12 drives the composite transmission cylinder 13 and the multiple extrusion rods 14 to automatically move downward, and automatically press the first panel component 2 and the second panel component 3 after centering. The specific pressing force of the extrusion rod 14 can be exerted on the first pressure sensor 143 by the reaction force of the I-shaped pressure rod 141 inside the extrusion rod 14, so that the first pressure sensor 143 outputs pressure data for disguised feedback. The third step is secondary pressing; The first panel component 2 and the second panel component 3 after centering and pressing are placed in an existing vacuum laminating machine for secondary pressing, thereby making the first panel component 2 and the second panel component 3 tightly fit together while ensuring the appearance dimensional accuracy of the assembly and fully ensuring the structural strength of the assembly of the first panel component 2 and the second panel component 3; The fourth step is molding; The pressed first panel component 2 and the second panel component 3 are laser-welded by using existing laser equipment, so that the first panel component 2 and the second panel component 3 are integrally formed and connected.
