Description

Technical Field

[0001] The present application relates to the field of flexible screen technology, and in particular to an integrated gluing and curing device. Background Art

[0002] The flexible screen module manufacturing process involves two steps: BPL (Backplane Lamination) adhesive coating and UV (Ultraviolet) curing. UV curing of BPL adhesive involves the generation of active free radicals by the photoinitiator (or photosensitizer) in the adhesive under UV irradiation, triggering a cross-linking reaction that rapidly converts the BPL adhesive from a liquid to a solid state. During UV curing, oxygen on the surface of the BPL adhesive quickly captures the active free radicals generated by photoinitiation, hindering the cross-linking reaction and affecting the adhesive's surface drying. Currently, UV curing equipment uses nitrogen air knives to blow oxygen away from the BPL adhesive surface, thereby preventing oxygen from capturing the active free radicals generated by photoinitiation.

[0003] However, even after adding nitrogen air knives to UV curing equipment, approximately 4% of oxygen still remains on the surface of the BPL adhesive. Therefore, reducing the exposure time of the BPL adhesive to the atmosphere after the flexible display module is coated and reducing the oxygen on the BPL adhesive surface during the UV curing process has become an urgent problem.

[0055] The flexible screen module manufacturing process includes two processes of BPL glue coating and UV curing. UV curing of BPL glue is that the photo initiator (or photosensitizer) in BPL glue produces active radicals under the irradiation of ultraviolet light, initiates crosslinking reaction, and makes BPL glue quickly change from liquid state to solid state. When UV curing, the oxygen on the surface of BPL glue will quickly snatch the active radicals produced by photo initiation, hinder the crosslinking reaction of BPL glue, and affect the surface drying effect of BPL glue. Further, when the CG (Cover Glass, outer screen) of the flexible screen is attached, the BPL glue will interfere with the CG to print residual glue, affect the CG cause value and assembly effect (probability of delamination), and potential reliability (pulling, dropping, etc. Test) failure risk after whole machine assembly.

[0056] Currently, after the gluing equipment performs the gluing process on the flexible screen module under atmospheric conditions, the gluing flexible screen module is transferred to the UV curing equipment under atmospheric conditions for the UV curing process. In order to prevent oxygen from preempting the active free radicals generated by light initiation, the UV curing equipment is provided with a nitrogen air knife. The nitrogen air knife is provided with two rows of air holes that are evenly distributed and have the same angle. The mounting base of the nitrogen air knife is designed to be adjustable up and down, and the wind direction angle of the nitrogen air knife can be rotated and adjusted. During the UV curing process, the UV curing equipment uses the nitrogen air knife to blow oxygen off the surface of the BPL glue to prevent oxygen from preempting the active free radicals generated by light initiation.

[0057] However, after the flexible display module is coated, it is transferred to the UV curing equipment in an atmospheric environment. The BPL adhesive is exposed to the atmosphere for a long time, and even after the UV curing equipment adds a nitrogen air knife, approximately 4% of oxygen remains on the surface of the BPL adhesive. Therefore, how to reduce the exposure time of the BPL adhesive to the atmosphere after the flexible display module is coated and reduce the oxygen on the BPL adhesive surface during the UV curing process has become an urgent problem.

[0058] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

The UV lamp 130 is inserted into the UV lamp groove 111 from the outer side of the top wall of the first shell 110. The UV lamp groove 111 can be integrally formed with the first shell 110. In this way, by providing the downwardly protruding UV lamp groove 111 on the top wall of the first shell 110, the problem that the wire harness of the UV lamp 130 penetrates the top wall of the first shell 110 when the UV lamp 130 is arranged inside the first shell 110, thereby reducing the sealing performance of the closed space structure, can be avoided.

[0084] Continuing as shown in Figure 3 In some implementations, the side wall of the first shell 110 is provided with a transparent window 112.

[0085] In the implementation, the side wall of the first shell 110 can be provided with a transparent window 112. The shape, number, position, and size of the transparent window 112 can be flexibly set according to actual needs, and the embodiments of the present application are not limited thereto. For example, the transparent window 112 can be arranged on the four side walls of the first shell 110, and the shape can be rectangular or elliptical, and the position can be close to the bottom of the side wall of the first shell 110. In this way, the production personnel can inspect the glue coating process and UV curing process of the BPL glue at any time through the transparent window 112.

[0086] It should be noted that, Figure 3Only some components of the glue coating and curing integrated device 100 are schematically shown, and the actual shape, actual size, actual position and actual structure of these components are not affected by the present invention. Figure 3 limitation.

[0087] Figure 4 This is a schematic diagram of the second part of the structure of the gluing and curing integrated device provided in the embodiment of the present application. Figure 4 As shown, in some embodiments, the integrated gluing and curing device 100 further includes an alignment visual camera 190, which is disposed in the second shell 120, and the module carrier 140 is mounted on the alignment visual camera 190, and the lens of the alignment visual camera 190 faces the module carrier 140, and the module carrier 140 is a transparent module carrier.

[0088] In practice, in order to prevent the position deviation of the flexible screen module from affecting the gluing process, the gluing and curing integrated device 100 also includes an alignment visual camera 190. The alignment visual camera 190 is arranged in the second shell 120, and the module carrier 150 is mounted on the alignment visual camera 190. The lens of the alignment visual camera 190 faces the module carrier 150 and is used to take pictures of the flexible screen module placed on the module carrier 150. Accordingly, in order to enable the alignment visual camera 190 to take pictures of the flexible screen module placed on the module carrier 150, the module carrier 150 is a transparent module carrier. In the case where the gluing and curing integrated device 100 includes multiple module carriers 150, each module carrier 150 corresponds to a group of alignment visual cameras 190, and a group of alignment visual cameras 190 includes at least one alignment visual camera 190. Accordingly, each module carrier 150 is mounted on its corresponding group of alignment visual cameras 190. In this way, the position deviation of the flexible screen module placed on the module carrier 150 is detected by the alignment visual camera 190, thereby preventing the position deviation of the flexible screen module from affecting the gluing process.

[0089] Continue as Figure 4 As shown, in some embodiments, a first sealing rubber ring 122 is provided on the top of the side wall of the first shell 110 and / or the second shell 120 .

[0090] In practice, to further enhance the sealing performance of the enclosed space structure formed by the first housing 110 and the second housing 120, a first sealing rubber ring 122 may be provided at the top end of the sidewalls of the first housing 110 and / or the second housing 120. This embodiment of the present application uses the example of providing the first sealing rubber ring 122 at the top end of the sidewall of the second housing 120. The case of providing the first sealing rubber ring 122 at the top end of the sidewall of the first housing 110 is similar and will not be further described.

[0091] It should be noted that Figure 4Only some components included in the second shell 120 are shown schematically, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 4 .

[0092] Figure 5 A third partial structural schematic view of the gluing and curing integrated equipment provided by the embodiments of the present application is shown. As shown in Figure 1 , Figure 2 and Figure 5 , in some embodiments, the vacuum extraction pipeline 160 includes an air extraction pipe 161, a butt flange 162, a pipe base 163 and a fourth moving device 164. The first end of the air extraction pipe 161 is connected to the butt flange 162, and the air extraction pipe 161 is arranged on the fourth moving device 164 through the pipe base 163 and can move in the direction of approaching or moving away from the second shell 120 to connect the butt flange 162 to the air extraction hole 121.

[0093] In implementation, the first end of the air extraction pipe 161 is provided with the butt flange 162 connected to the air extraction hole 121 opened on the second shell 120. The air extraction pipe 161 is arranged on the fourth moving device 164 through the pipe base 163, and when the first shell 110 is closed with the second shell 120, the fourth moving device 164 can drive the air extraction pipe 161 to move in the direction of approaching the second shell 120 to connect the butt flange 162 to the air extraction hole 121. Then, after the gluing device 140 completes the gluing process of the flexible screen module to be glued, the closed cavity structure is extracted to a vacuum state.

[0094] Continuing as shown in Figure 5 , in some embodiments, the butt flange 162 is provided with a second sealing rubber ring 1621 corresponding to the air extraction hole 121.

[0095] In implementation, the butt flange 162 is provided with the sealing rubber ring 1621 corresponding to the air extraction hole 121. In this way, the sealing property during vacuum extraction can be improved.

[0096] Continuing as shown in Figure 1 , Figure 2 and Figure 5 , in some embodiments, the fourth moving device 164 is a sixth guide rail structure arranged along the direction of the air extraction pipe 161 approaching or moving away from the second shell 120.

[0097] In the implementation, the fourth moving device 164 can be a sixth guide rail structure arranged along the evacuation pipeline 161 in the direction close to or away from the second shell 120. The sixth guide rail can be a linear guide rail or a non-linear guide rail, and the embodiments of the present application are not limited thereto. In this way, after the first shell 110 and the second shell 120 are closed to form a sealed cavity structure, the fourth moving device 164 can drive the evacuation pipeline 161 to close the evacuation hole 121. After the UV curing process, the fourth moving device 164 can drive the evacuation pipeline 161 to disconnect the evacuation hole 121.

[0098] In some embodiments, the gluing and curing integrated device 110 further comprises a vacuum pump connected to the second end of the evacuation pipeline 161.

[0099] In the implementation, the gluing and curing integrated device 110 further comprises a vacuum pump. The vacuum pump is connected to the second end of the evacuation pipeline 161, and is used to evacuate the sealed cavity structure formed by closing the first shell 110 and the second shell 120 to a vacuum state through the evacuation pipeline 161, so as to avoid the problem of oxygen on the surface of the BPL adhesive competing with the active free radicals generated by the UV curing process.

[0100] It should be noted that, Figure 5 Only some components included in the gluing and curing integrated device 110 are schematically shown, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 5 the description.
