Description

Technical Field

[0001] This utility model belongs to the field of OLED screen patch technology. Specifically, this utility model relates to a patch nozzle structure. Background Technology

[0002] During the CG bonding process of OLED products, when the robotic arm completes the bonding of a single home module, the CG module may slip or deviate. Currently, the robotic arm of the machine has a UV pre-curing function, but in most cases, the UV pre-curing energy is reduced. This is because the adhesive in the pre-curing area solidifies prematurely, resulting in obvious Mura (uniform brightness of the display) in the pre-cured area after bonding. Furthermore, air bubbles are generated on the bonding surface, i.e., in the pre-cured light outlet area. Due to the sealing of the pre-cured light outlet, the adhesive in this light outlet area solidifies prematurely, and the air bubbles cannot be expelled, causing air bubbles to appear in the bonding area.

[0003] To address the aforementioned issues, patent document 214411161U discloses a suction nozzle device for improving module slippage during patch bonding. By setting a ring of light-emitting ports around the nozzle body, with the center of the light-emitting ports serving as the vacuum port, this device ensures normal pre-curing during product bonding while preventing unevenness during the pre-curing process. However, it fails to resolve the issue of air bubbles forming on the bonding surface, specifically in the pre-cured light-emitting port area, during adhesive curing. Furthermore, the closed nature of the pre-cured light-emitting ports causes premature curing of the adhesive in this area, preventing the air bubbles from being expelled and resulting in air bubbles in the bonding area.

[0004] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the existing patch nozzles. Utility Model Content

[0005] This utility model is designed to solve the aforementioned problems. Its purpose is to provide a patch nozzle structure that improves the uniformity of UV pre-curing during CG bonding of OLED screen products, and avoids the problem of air bubbles failing to escape while meeting bonding requirements. To achieve the above objective, the technical solution adopted by this utility model is as follows:

[0012] The technical effects of this utility model are as follows: The patch nozzle structure provided by this utility model includes a nozzle body and a nozzle pad disposed on the nozzle body.
