DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] Compared with traditional LCD screens, flexible screens have advantages such as higher contrast, wider viewing angle and faster response speed, and have gradually developed into the current mainstream trend. With the continuous development of display technology, the application areas of flexible screens are also expanding, from smart phones, tablets, wearable devices, to smart homes, industrial control and medical, innovative commercial and other fields. In the preparation process of the traditional curved display screen of flexible screens, by bonding the flexible screen body with the curved cover plate, combining the self-luminous characteristics of the flexible screen body and the three-dimensional shape of the curved cover plate, the display screen presents a 3D shape.

[0031] The traditional bonding method uses optical clear resin (OCR) or optical adhesive (OCA) to completely bond the cover plate to the flexible screen. However, in the actual bonding process, bubbles still exist after the screen and the curved cover plate are bonded, especially at the four corners of the screen and the curved cover plate, resulting in poor bonding and low product yield.

[0032] Therefore, there is an urgent need for a bonding component to solve the problem of poor bonding effect in traditional bonding methods.

[0033] The inventors have found that in the traditional bonding method, the straight edge of the screen is subjected to greater compression during the bonding process, resulting in a better bonding effect, while the four corners of the screen and the cover plate are subjected to insufficient compression force, which may result in the problem of bubbles being unable to be discharged.

[0034] Therefore, the present application provides a bonding component, which can increase the extrusion pressure at the four corners of the cover plate and the screen body during the bonding process through multiple auxiliary bonding parts, thereby reducing the generation of bubbles and improving product yield.

[0035] In order to better understand this application, Figures 1 to 8 The bonding assembly provided in the embodiment of the present application is described in detail.

[0036] Figure 1 Shown is a schematic diagram of a bonding assembly provided in one embodiment of the present application. Figure 2 Shown is a front view of a fitting assembly provided in one embodiment of the present application. Figure 3 The figure is a schematic diagram of the structure of the bonding assembly provided by one embodiment of the present application. Figures 1 to 3 As shown, the fitting assembly 100 includes a fixing member 101 , a flexible pad 102 and a plurality of auxiliary fitting members 103 .

[0037] Specifically, the fixing member 101 is used to fix the cover plate 104 to be attached, and the cover plate 104 has a plurality of recessed corners 1041. The flexible pad 102 is arranged opposite to the fixing member 101 in the first direction X. The flexible pad 102 has a plurality of raised corners 1021, and the plurality of raised corners 1021 are configured to squeeze the corner point area of ​​the flexible screen body 105 to the plurality of recessed corners 1041.

[0038] For example, Figure 1 As shown, the plurality of auxiliary fittings 103 are respectively connected to the plurality of raised corners 1021. Figure 3 As shown, the plurality of auxiliary fittings 103 are respectively in contact with the plurality of raised corners 1021 .

[0039] Exemplarily, the cover plate 104 has a plurality of recessed corners 1041, such as Figures 1 to 3 As shown, the cover plate 104 has a plurality of recessed corners 1041 , and the edge of the cover plate 104 is in a curved shape, that is, the cover plate 104 is a curved cover plate.

[0040] Exemplarily, the flexible pad 102 may be a contoured PAD, and the shape of the contoured PAD may be adapted according to the shape requirements of the product. The material of the flexible pad 102 includes silicone material, propylene oxide, thermoplastic polyurethane elastomer rubber, polyurethane and other materials. It should be understood that in practical applications, the material of the flexible pad 102 can be selected according to requirements, and the material can have good elasticity and flexibility to meet the requirements for the flexible pad 102.

[0041] For example, when the plurality of auxiliary fittings 103 are respectively in contact with the plurality of raised corners 1021, the elastic modulus of the plurality of auxiliary fittings 103 may be higher than the elastic modulus of the flexible pad 102, thereby increasing the extrusion of the auxiliary fittings 103 on the flexible pad 102 during the contact, thereby improving the extrusion effect of the plurality of raised corners 1021 on the corner area of ​​the flexible screen 105 to the plurality of recessed corners 1041, thereby ensuring the fitting effect. In actual application, the elastic modulus of the auxiliary fittings 103 may be selected according to requirements.

[0042] Exemplarily, the number of the plurality of auxiliary fittings 103 corresponds to the number of the plurality of raised corners 1021. For example, when the flexible pad 102 includes four raised corners, the number of the auxiliary fittings 103 is four, which are respectively connected to or abut against the four raised corners.

[0043] The embodiment of the present application uses multiple auxiliary bonding parts to be connected or abutted with multiple raised corners respectively, so that the extrusion pressure at the raised corners is enhanced. When the multiple raised corners squeeze the corner area of ​​the flexible screen body to the multiple recessed corners, the corner area of ​​the flexible screen body can be subjected to sufficient extrusion pressure, so that the bubbles between the corner area of ​​the flexible screen body and the cover plate can be squeezed, thereby achieving the purpose of bubble discharge, thereby reducing the bubbles between the flexible screen body and the cover plate, improving the bonding effect, and thus improving the product yield.

[0044] Figure 4 FIG. 1 is a side view of a bonding assembly provided by an embodiment of the present application. Figure 4 As shown, in the bonding assembly provided by the embodiment of the present application, when multiple auxiliary bonding pieces 103 are respectively abutted against multiple raised corners 1021, the bonding assembly 100 also includes: a support platform 106, which is configured to support the flexible pad 102 and multiple auxiliary bonding pieces 103; wherein the auxiliary bonding pieces 103 are located at one end of the raised corner 1021 away from the fixing piece 101.

[0045] For example, the support platform 106 supports the flexible pad 102 and the plurality of auxiliary laminating parts 103. During the box lifting process, the generation of bubbles during the laminating process can be reduced by precisely controlling the movement and pressure of the support platform 106 and / or the fixing part 101, thereby improving the laminating effect. In particular, in the laminating of curved display screens, precise control can reduce the generation of bubbles during the laminating process and improve the product yield.

[0046] For example, the material of the support platform 106 can be selected according to the needs to meet the specific requirements of the bonding component, such as heat resistance, impact resistance, weight, cost and processing difficulty. In addition, the material of the support platform 106 needs to be able to withstand the pressure during the bonding process and ensure precise alignment, so as to achieve the purpose of ensuring the bonding quality.

[0047] Exemplarily, when the flexible pad 102 and the multiple auxiliary bonding parts 103 are placed on the support table 106, the support table 106 has a positioning portion to position the flexible pad 102 and the multiple auxiliary bonding parts 103, thereby ensuring the accuracy of the relative position of the cover plate 104 and the flexible pad 102 and the multiple auxiliary bonding parts 103, thereby ensuring the accuracy of the relative position of the cover plate 104 and the flexible screen body 105, and improving the bonding effect.

[0048] The embodiment of the present application supports the flexible pad and multiple auxiliary bonding parts through a support platform. While ensuring the stability of the flexible pad and multiple auxiliary bonding parts during the bonding process, it can also ensure the accuracy of the relative position of the flexible pad and multiple auxiliary bonding parts and the cover plate, thereby further improving the bonding effect.

[0049] Figure 5 Shown Figure 3The enlarged schematic diagram of A is shown. Figure 5 As shown, the shape of the side of the auxiliary fitting 103 close to the raised corner 1021 provided in the embodiment of the present application is respectively adapted to the shape of the side of the raised corner 1021 close to the auxiliary fitting 103 .

[0050] Exemplarily, the shape of the side of the auxiliary adhesive piece 103 near the raised corner 1021 is respectively the same as the shape of the side of the raised corner 1021 near the auxiliary adhesive piece 103; or, the shape of the side of the auxiliary adhesive piece 103 near the raised corner 1021 is respectively the same as the size and proportion of the shape of the side of the raised corner 1021 near the auxiliary adhesive piece 103.

[0051] Exemplarily, the shape of the side of the auxiliary fitting 103 close to the raised corner 1021 is respectively the same as the shape of the side of the raised corner 1021 close to the auxiliary fitting 103, and the multiple auxiliary fittings 103 are respectively in good contact and tight fit with the multiple raised corners 1021, thereby ensuring uniform extrusion force and improving the fitting effect.

[0052] The shape of the side of the auxiliary bonding piece of the bonding assembly provided in the embodiment of the present application close to the shape of the side of the raised corner close to the auxiliary bonding piece is respectively adapted to the shape of the side of the raised corner close to the auxiliary bonding piece, which can ensure that when multiple auxiliary bonding pieces are respectively in contact with multiple raised corners, the auxiliary bonding pieces are respectively in good contact with the multiple raised corners, thereby ensuring uniform extrusion force during the bonding process, thereby improving the bonding effect.

[0053] Figure 6 Shown Figure 5 The exploded diagram of the structure shown. Figure 6 As shown, in one embodiment of the present application, the surface of the protruding corner 1021 close to the auxiliary fitting 103 is a first curved surface 10211 , and the surface of the auxiliary fitting 103 close to the flexible pad 102 is a second curved surface 1031 .

[0054] Exemplarily, the height of the upper surface of the auxiliary fitting 103 in the vertical direction is smaller than the height of the upper surface of the raised corner 1021 in the vertical direction, the side surface of the raised corner 1021 close to the auxiliary fitting 103 is a first curved surface 10211, and the surface of the auxiliary fitting 103 close to the flexible pad 102 is a second curved surface 1031, and the height of the second curved surface 1031 along the vertical direction is smaller than the height of the first curved surface 10211.

[0055] In some embodiments, the radius of the first curved surface 10211 is the same as the radius of the second curved surface 1031. That is, the curvature radii of the first curved surface 10211 and the second curved surface 1031 match.

[0056] In the embodiment of the present application, the surface of the side of the protruding corner close to the auxiliary bonding piece is a first curved surface, and the surface of the side of the auxiliary bonding piece close to the flexible pad is a second curved surface. The design of the curved surface can meet the requirements of the point angle area of ​​the flexible screen body and the curved cover plate. In addition, in some embodiments, the radius of the first curved surface is the same as the radius of the second curved surface, which can simplify the processing technology of the auxiliary bonding piece and save the cost of the bonding component while ensuring that the shape of the side of the auxiliary bonding piece close to the protruding corner is respectively matched with the shape of the side of the protruding corner close to the auxiliary bonding piece.

[0057] Figure 7 Shown Figure 1 The enlarged schematic diagram of B is shown. Figure 7 As shown, in the laminating assembly provided by the embodiment of the present application, when a plurality of auxiliary laminating members 103 are respectively connected to a plurality of raised corners, the auxiliary laminating members 103 cover the raised corners 1021 .

[0058] Exemplarily, the flexible pad is a contoured PAD, and the four corner regions of the contoured PAD are curved corners, that is, the surfaces of the plurality of raised corners 1021 are arc surfaces, and the plurality of auxiliary adhesive members 103 cover the raised corners 1021. The area outside the region of the flexible pad 102 relative to the raised corners 1021 is a plane, and the plurality of auxiliary adhesive members 103 cover the portion of the raised corners 1021, and have a certain height relative to the plane surface of the flexible pad 102.

[0059] In some embodiments, the covering thickness of the auxiliary fitting 103 ranges from 0.1 mm to 0.4 mm.

[0060] Exemplarily, the plurality of auxiliary fittings 103 cover the raised corner 1021 portion, and the thickness range relative to the planar surface of the flexible pad 102 is 0.1 mm to 0.4 mm. The covering thickness of the auxiliary fittings 103 can be arbitrarily selected within the range of 0.1 mm to 0.4 mm according to requirements.

[0061] In some embodiments, the auxiliary bonding member 103 has a covering thickness of 0.4 mm. The inventors have found through experiments that when the covering thickness of the auxiliary bonding member 103 is 0.4 mm, the auxiliary bonding effect is best.

[0062] In the embodiment of the present application, when multiple auxiliary bonding members 103 are respectively connected to multiple raised corners, the auxiliary bonding members cover the raised corners, thereby achieving a bonding effect and simplifying the structure of the bonding component, thereby simplifying the processing technology of the bonding component.

[0063] In some embodiments, the material of the auxiliary fitting 103 is consistent with the material of the flexible pad 102; illustratively, when the material of the flexible pad 102 is silicone material, propylene oxide, thermoplastic polyurethane elastomer rubber, polyurethane and other materials, the material of the auxiliary fitting 103 is consistent with the material of the flexible pad 102, and correspondingly, the material of the auxiliary fitting 103 includes silicone material, propylene oxide, thermoplastic polyurethane elastomer rubber, polyurethane and other materials.

[0064] In some embodiments, the material of the auxiliary bonding member 103 includes silicone; illustratively, silicone has good elasticity and softness, which enables the flexible pad 102 to deform during the bonding process, thereby generating a certain elastic support force for the flexible screen body, and improving the bonding accuracy. In addition, during the bonding process, the glue may need to be heated. With the heating component, the silicone can maintain stability in a high temperature environment, so that the stability and reliability of the bonding component under high temperature working conditions are guaranteed. In addition, silicone is resistant to many chemicals and is not easily corroded, so it has a wider range of uses, thereby increasing the scope of use of the bonding component.

[0065] In some embodiments, the auxiliary fitting 103 is integrally formed with the flexible pad 102. Exemplarily, the process of integrally forming the auxiliary fitting 103 and the flexible pad 102 simplifies the manufacturing process of the fitting component, and can greatly reduce the production time of the fitting component, thereby improving production efficiency. In addition, the integral forming process of the auxiliary fitting 103 and the flexible pad 102 reduces the number of molds, templates, etc., and simplifies the preparation of molds and templates, without the need for additional step-by-step processing, thereby reducing the production cost of the fitting component. In addition, the process of integrally forming the auxiliary fitting 103 and the flexible pad 102 can improve the production accuracy and repeatability of the auxiliary fitting component 103 and the flexible pad 102, thereby improving the quality of the finished product.

[0066] The embodiment of the present application simplifies the processing flow of the auxiliary fitting material and the flexible pad by making the material of the auxiliary fitting consistent with that of the flexible pad, and further simplifies the overall process of the fitting assembly by integrally molding the material of the auxiliary fitting and the flexible pad.

[0067] Figure 8 FIG. 2 is a schematic diagram of the structure of a bonding assembly provided by another embodiment of the present application. Figure 8 As shown, the fitting assembly 100 further includes: a plurality of limiting members 107 disposed around the flexible pad 102 , and the limiting members 107 are configured to limit the displacement of the flexible pad 102 in the horizontal direction.

[0068] Exemplarily, the limiter 107 can position the flexible pad 102 and limit the displacement of the flexible pad 102 in the horizontal direction, thereby ensuring the precise alignment of the flexible screen 105 and the cover plate 104 during the bonding process, and avoiding poor bonding due to position deviation. Therefore, by using the limiter 107, the bonding accuracy can be improved and the quality of bonding can be ensured. The limiter 107 can also prevent the flexible pad 102 from tilting, thereby avoiding the tilting and displacement of the flexible screen 105 during the bonding process, maintaining the horizontal state of the flexible screen 105, and protecting the corners of the flexible screen 105 during the bonding process, thereby further improving the quality of bonding and ensuring the product yield. In addition, the limiter positions the corners of the flexible screen 105 by limiting the displacement of the flexible pad 102 in the horizontal direction, thereby improving the accuracy of bonding during the bonding process.

[0069] For example, Figure 8 The number of the stoppers 107 shown in the figure is two, which can prevent the flexible pad from being displaced in the horizontal direction during the bonding process. It should be understood that in actual application, the number of the stoppers 107 can be selected according to requirements.

[0070] The bonding assembly provided in the embodiment of the present application realizes the horizontal displacement of the flexible pad by setting a plurality of limit members 107, thereby ensuring the precise alignment of the flexible screen and the cover during the bonding process, and avoiding the problem of poor bonding due to position deviation of the flexible screen and the cover.

[0071] In some embodiments, multiple auxiliary fittings 103 are detachably connected to the support platform 106. The multiple auxiliary fittings of the fitting assembly provided in the embodiment of the present application are detachably connected to the support platform, which can meet different size requirements, facilitate multiple auxiliary fittings to cooperate with the flexible pad, and achieve the purpose of expanding the application range of the fitting assembly.

[0072] Combine the following Fig. 9 The laminating device provided in the embodiment of the present application is described in detail. Fig. 9 Shown is a schematic structural diagram of a bonding device provided in one embodiment of the present application.

[0073] like Fig. 9 As shown, the laminating device 200 includes: a laminating component 100; and a power component 210 configured to provide power to the fixing member 101 or the flexible pad 102 of the laminating component 100, so that the fixing member 101 and the flexible pad 102 move relative to each other.

[0074] Exemplarily, the power assembly 210 includes a solenoid valve, a cylinder, etc., which are used to control the pressure and movement during the bonding process. In addition, the power assembly 210 may also include a vacuum pump, a heating mechanism or a pressure control device, etc. The vacuum pump is used to create and maintain a vacuum environment, which provides a prerequisite for removing bubbles generated during the bonding process and ensuring close contact between the bonding materials. During the bonding process, heating may be required to activate the viscosity of the bonding agent (such as OCA glue or OCR glue), and the heating plate or heating tube will be evenly arranged to provide the required heat. During the bonding process, the bonding pressure of the bonding device is an important factor affecting the bonding quality, so it is necessary to use a pressure control device to ensure that the bonding pressure is within a set range.

[0075] The bonding device provided in the embodiment of the present application has the same beneficial effects as the bonding assembly mentioned above, which will not be described in detail here.

[0076] Fig.10 FIG. 1 is a schematic diagram of a process flow of a bonding method provided in an embodiment of the present application. Fig.10 As shown, the bonding method provided in one embodiment of the present application includes the following steps.

[0077] Step S110, fixing the cover plate to the fixing member, wherein the cover plate has a plurality of recessed corners.

[0078] Step S120: placing the flexible screen body on the flexible pad and the auxiliary bonding member.

[0079] Step S130, making the flexible pad and the auxiliary laminating member move relative to the fixing member to laminat the flexible screen body and the cover plate.

[0080] For example, before lamination, the cover plate and the flexible screen body can be processed as needed to ensure that there is no dust and impurities. During the lamination process, the flexible screen can be placed on the guide film, and then the flexible screen body and the guide film are placed on the flexible pad and the auxiliary lamination member. The guide film can assist in alignment to ensure accurate alignment during the lamination process, thereby ensuring product yield and product performance.

[0081] For example, during the bonding process, the glue is evenly coated on the flexible screen, and necessary treatment of the glue such as heating the glue is performed. After the bonding is completed, if a bonding process using UV optical glue is used, UV ultraviolet curing is required to ensure the rapid curing and bonding strength of the bonding material. In addition, during the bonding process, the bonding temperature, pressure and other parameters can be adjusted according to needs to ensure the bonding effect.

[0082] The bonding method provided in the embodiment of the present application has the same beneficial effects as the above-mentioned bonding assembly and will not be described in detail here.
