[0035] The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0036] like Figure 1-Figure 3 As shown, the present application provides an oxygen isolation mechanism 100, which includes a frame 110 and an airbag 120. The oxygen isolation mechanism 100 is used to isolate the anaerobic adhesive layer of the display module from oxygen, facilitating subsequent oxygen-isolating curing of the anaerobic adhesive layer. The display module includes a display screen, an anaerobic adhesive layer, and a cover glass stacked in sequence. The anaerobic adhesive layer is used to bond the display screen and the cover glass together.

[0037] The frame 110 has a sealed cavity 111, an airflow channel 112, and a notch 113. The sealed cavity 111 is connected to the notch 113, allowing the anaerobic adhesive layer of the display module to enter the sealed cavity 111 through the notch 113. The airflow channel 112 has an air inlet 1121 and an air outlet 1122. The air inlet 1121 is used to allow non-oxygen gas to enter, and the air outlet 1122 is connected to the sealed cavity 111. When non-oxygen gas is introduced into the air inlet 1121, it can flow along the airflow channel 112 and through the air outlet 1122 into the sealed cavity 111.

[0038] The airbag 120 is disposed in the notch 113 and is connected to the airflow channel 112 so that part of the non-oxygen gas in the airflow channel 112 can enter the interior of the airbag 120, thereby increasing the filling volume of the airbag 120 and clamping the display module to clamp the display module to connect it to the oxygen isolation mechanism 100.

[0039] When the display module is clamped in the notch 113, that is, when the display module is clamped on the airbag 120, the anaerobic adhesive layer is at least partially located inside the sealed cavity 111. There is a gap between the display module and the notch 113, and the gap is connected to the outside world, so that the non-oxygen gas filled into the sealed cavity 111 can replace the oxygen gathered inside the anaerobic adhesive layer or the oxygen filled around the anaerobic adhesive layer to the outside world through the gap, so as to perform oxygen-proof curing on the anaerobic adhesive layer. It should be noted that in the present application, the gas filled into the airflow channel 112 is a non-oxygen gas, so that the anaerobic adhesive layer can be cured in an oxygen-free environment. The non-oxygen gas refers to gases other than oxygen, including but not limited to nitrogen or inert gas.

[0040] The above-mentioned oxygen isolation mechanism 100 can clamp the display module at the notch 113, and make the anaerobic adhesive layer at least partially located inside the sealed cavity 111, and introduce non-oxygen gas toward the air inlet 1121 of the air flow channel 112. Part of the non-oxygen gas is filled into the air bag 120, so that the air bag 120 is filled and clamps the display module, thereby clamping the display module to the oxygen isolation mechanism 100, and another part of the non-oxygen gas enters the sealed cavity 111 through the air outlet 1122. Since there is a gap between the display module and the notch 113, at this time, the non-oxygen gas filled into the sealed cavity 111 can replace the oxygen gathered inside the anaerobic adhesive layer or the oxygen filled around the anaerobic adhesive layer to the outside through the gap, thereby oxygen-isolating and curing the anaerobic adhesive layer. The oxygen isolation mechanism 100 provided in the present application can replace the oxygen inside or around the anaerobic adhesive layer to the outside world only by inflation. The oxygen isolation curing method of the anaerobic adhesive layer is simple, and the oxygen isolation mechanism 100 is small in size, which is convenient to carry to various scenarios for oxygen isolation curing of the anaerobic adhesive layer, thereby broadening the application scenarios of the oxygen isolation mechanism 100.

[0041] In one embodiment, if Figure 1-Figure 3 As shown, the frame 110 includes a top wall 114, a bottom wall 115, and a plurality of side walls 116. The plurality of side walls 116 connect the top wall 114 and the bottom wall 115. That is, the frame 110 is surrounded by the top wall 114, the bottom wall 115, and the plurality of side walls 116. A notch 113 is defined in the peripheral side wall 116 of the frame 110, and the notch 113 passes through the side wall 116. The two ends of the notch 113 are respectively located on two opposite side walls 116 of the frame 110. In other words, the notch 113 is defined on the side wall 116 of the frame 110, and the extension direction of the notch 113 is consistent with the peripheral direction of the side wall 116. The notch 113 is connected to the sealed cavity 111 and is also connected to the outside world. On the one hand, the setting of the notch 113 allows the anaerobic adhesive layer area in the display module to enter the sealed cavity 111. On the other hand, the notch 113 can form a gap with the display module, through which the oxygen accumulated in the anaerobic adhesive layer or the oxygen surrounding the anaerobic adhesive layer can be replaced to the outside world, thereby isolating and curing the anaerobic adhesive layer.

[0042] In order to cure the anaerobic adhesive layer that enters the sealing cavity 111, a preferred embodiment is as follows: Figure 1-Figure 3As shown, the top wall 114 is at least partially a transparent structure, and the orthographic projection of the transparent structure of the top wall 114 in the thickness direction thereof is located within the sealed cavity 111, and / or the bottom wall 115 is at least partially a transparent structure, and the orthographic projection of the transparent structure of the bottom wall 115 in the thickness direction thereof is located within the sealed cavity 111. In one embodiment, only the top wall 114 is at least partially a transparent structure, and the orthographic projection of the transparent structure of the top wall 114 in the thickness direction thereof is located within the sealed cavity 111. For example, if the top wall 114 is formed integrally of transparent glass through injection molding, extrusion, or the like, ultraviolet rays can be intermittently irradiated toward the transparent structure of the top wall 114, so that the ultraviolet rays can act on the surface of the anaerobic adhesive layer, thereby curing the anaerobic adhesive layer. In another embodiment, only the bottom wall 115 is at least partially transparent, and the orthographic projection of the transparent structure of the bottom wall 115 in its thickness direction is located within the sealed cavity 111. For example, the bottom wall 115 is made of transparent glass and integrally formed by injection molding, extrusion, or the like. By intermittently irradiating ultraviolet light toward the transparent structure of the bottom wall 115, the ultraviolet light can act on the surface of the anaerobic adhesive layer, thereby curing the anaerobic adhesive layer. In yet another embodiment, at least a portion of both the top wall 114 and the bottom wall 115 is provided with a transparent structure. For example, both the top wall 114 and the bottom wall 115 are made of transparent glass and integrally formed by injection molding, extrusion, or the like. The orthographic projection of the transparent structure of the top wall 114 in its thickness direction is located within the sealed cavity 111, and the orthographic projection of the transparent structure of the bottom wall 115 in its thickness direction is located within the sealed cavity 111. By intermittently irradiating ultraviolet light toward the transparent structure of the top wall 114 and / or the bottom wall 115, the ultraviolet light can act on the surface of the anaerobic adhesive layer, thereby curing the anaerobic adhesive layer.

[0043] In order to clamp and connect the display module to the oxygen isolation mechanism 100, in one embodiment, Figure 1-Figure 3 As shown, the airflow channel 112 is opened in the side wall 116, and the extension direction of the airflow channel 112 is consistent with the peripheral direction of the frame 110. The airflow channel 112 has an opening connected to the notch 113. The airbag 120 is sealed at the opening of the airflow channel 112. For example, the airbag 120 is set on the airflow channel 112 by sleeves, embedding, etc., and the interface end of the airbag 120 covers the opening of the airflow channel 112. This allows the non-oxygen gas filled in the airflow channel 112 to enter the airbag 120 through the opening. The airbag 120 is filled and clamps the display module to clamp the display module to the oxygen isolation mechanism 100. Since the airbag 120 is flexible, the airbag 120 has a better fit with the display module after being filled. The airbag 120 can effectively seal the sealed cavity 111, thereby improving the sealing reliability of the sealed cavity 111.

[0044] In order to improve the oxygen replacement efficiency of the anaerobic adhesive layer, in one embodiment, Figure 1-Figure 3As shown, there are multiple gas outlets 1122, and the multiple gas outlets 1122 are spaced apart along the extension direction of the airflow channel 112. For example, in this embodiment, the multiple gas outlets 1122 can be spaced apart and arranged on the side wall 116, and the multiple gas outlets 1122 are interconnected with the airflow channel 112 and the sealed cavity 111. When non-oxygen gas is introduced into the airflow channel 112, the non-oxygen gas can quickly enter the sealed cavity 111 through the multiple gas outlets 1122, thereby quickly replacing the oxygen inside the sealed cavity 111 and the inside and surrounding anaerobic adhesive layer with the outside, thereby improving the oxygen replacement efficiency of the anaerobic adhesive layer and thereby improving the curing efficiency of the anaerobic adhesive layer.

[0045] Among them, the number of air outlets 1122 can be two, three or other numbers. This application does not limit the specific number of air outlets 1122, and it can be actually set according to user needs.

[0046] In one embodiment, if Figure 1-Figure 3 As shown, the oxygen isolation mechanism 100 further includes a regulating valve 130, which is connected to the air inlet 1121 by means of screw connection, clamping connection, etc., and is used to adjust the amount of air at the air inlet 1121. Since the replacement efficiency of the oxygen in and around the anaerobic adhesive layer is related to the air pressure in the sealed cavity 111, when the amount of air entering the sealed cavity 111 is large, the air pressure in the sealed cavity 111 is high. At this time, under the action of atmospheric pressure, the oxygen in and around the anaerobic adhesive layer can be quickly discharged to the outside. Conversely, when the amount of air entering the sealed cavity 111 is small, the air pressure in the sealed cavity 111 is low. At this time, under the action of low air pressure, the rate at which the oxygen in and around the anaerobic adhesive layer is discharged to the outside is slow.

[0047] The oxygen isolation mechanism 100 can adjust the air intake volume of the air inlet 1121 through the regulating valve 130 to adjust the oxygen replacement efficiency inside and around the anaerobic adhesive layer, thereby improving the curing controllability of the anaerobic adhesive layer of the display module.

[0048] It should be noted that, in other embodiments, a regulating valve 130 may be connected to the air outlet 1122 by screwing, clamping, or the like to adjust the air volume at the air outlet 1122. Alternatively, regulating valves 130 may be connected to both the air inlet 1121 and the air outlet 1122 by screwing, clamping, or the like to adjust the air volume at the air inlet 1121 and the air outlet 1122.

[0049] In addition, if Figure 1-Figure 4 As shown, the present application provides a curing method, which uses the oxygen isolation mechanism 100 of any of the above technical solutions to isolate the anaerobic adhesive layer of the display module from oxygen. The curing method of the anaerobic adhesive layer includes the following steps:

[0050] Step S110: Clamp the display module into the notch 113, ensuring that the anaerobic adhesive layer is at least partially located within the sealed cavity 111. A gap is formed between the display module and the notch 113, which is in communication with the outside world. Specifically, the display module to be cured is placed into the notch 113 manually or by a robot, initially securing the display module to the frame 110. The area of the anaerobic adhesive layer to be cured is located within the sealed cavity 111, ensuring that a gap exists between the display module and the notch 113 when the display module is clamped into the notch 113.

[0051] Step S120: Fill the airflow channel 112 with a non-oxygen gas. Part of the non-oxygen gas enters the airbag 120, filling the airbag 120 and clamping the display module. Another part of the non-oxygen gas enters the sealed cavity 111. The non-oxygen gas filled into the sealed cavity 111 can replace the oxygen accumulated inside the anaerobic adhesive layer or the oxygen surrounding the anaerobic adhesive layer to the outside through the gap, so as to perform oxygen-proof curing on the anaerobic adhesive layer. Among them, the gas filled into the airflow channel 112 is a non-oxygen gas, which refers to a gas other than oxygen. For example, in the present embodiment, the non-oxygen gas filled into the airflow channel 112 is one of nitrogen and argon. Since nitrogen and argon have better stability, they can prevent the non-oxygen gas from reacting with the anaerobic adhesive layer. However, in other embodiments, the non-oxygen gas can also be helium, neon or other inert gases.

[0052] Step S130: curing the anaerobic adhesive layer processed in step S120.

[0053] The above-mentioned curing method can clamp the display module at the notch 113, and make the anaerobic adhesive layer at least partially located inside the sealed cavity 111, and introduce non-oxygen gas toward the air inlet 1121 of the air flow channel 112, and part of the non-oxygen gas is filled into the air bag 120, so that the air bag 120 is filled and clamps the display module, so as to clamp the display module and connect it to the oxygen isolation mechanism 100, and another part of the non-oxygen gas enters the sealed cavity 111 through the air outlet 1122. Since there is a gap between the display module and the notch 113, at this time, the non-oxygen gas filled into the sealed cavity 111 can replace the oxygen gathered inside the anaerobic adhesive layer or the oxygen filled around the anaerobic adhesive layer to the outside through the gap, so as to perform oxygen isolation and curing on the anaerobic adhesive layer.

[0054] In one embodiment, if Figure 4 As shown, step S130 specifically includes: irradiating ultraviolet light toward the interior of the sealed cavity 111, and allowing the ultraviolet light to act on the surface of the anaerobic adhesive layer to irradiate and oxygen-proof the anaerobic adhesive layer. In this embodiment, the energy of the ultraviolet light acting on the surface of the anaerobic adhesive layer is 3000mj / cm 2 As a result, the anaerobic adhesive layer irradiated by ultraviolet rays can be quickly cured.

[0055] In one embodiment, the curing method provided by the present application can be applied to the glue repair process of the display module. Specifically, a display module is first provided, and there are bubbles at the edge of the anaerobic adhesive layer in the display module. Then, the needle of the syringe is inserted from the side of the anaerobic adhesive layer and the bubbles in the anaerobic adhesive layer are punctured, and the anaerobic adhesive is re-injected toward the punctured position of the bubble. Then, the display module is clamped in the notch 113 so that the newly injected anaerobic adhesive is located inside the sealed cavity 111. Non-oxygen gas is continuously injected into the air flow channel 112. Part of the non-oxygen gas enters the airbag 120, so that the airbag 120 is filled and clamps the display module. Another part of the non-oxygen gas enters the sealed cavity 111 to replace the oxygen gathered inside the anaerobic adhesive layer or the oxygen filled around the anaerobic adhesive layer to the outside world. Finally, ultraviolet light is irradiated on the surface of the anaerobic adhesive layer to irradiate and oxygen-proof cure the anaerobic adhesive layer, thereby remedying the undesirable phenomenon of bubbles at the edge of the display module and improving the production yield of the display module.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
