[0060] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0061] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0062] In the related art, a flexible screen is bonded to a curved cover plate by a bonding jig, thereby forming a curved screen. Figure 1 , Figure 2 As shown, the laminating device includes a laminating jig 1 for supporting the part to be laminated, the laminating jig 1 includes a supporting surface 10, the part to be laminated is specifically a flexible screen body 2, the supporting surface 10 includes a plane area 101 and an arc angle area 102, and the arc angle area 102 is arranged around the plane area 101. The flexible screen body 2 is pressed together by the plane area 101 and the arc angle area 102 of the supporting surface 10 to laminate with the curved cover plate 3, and the plane part and the curved part of the curved screen are formed correspondingly.

[0063] After long-term research, the inventors found that in the process of 3D curved surface bonding of the screen, due to insufficient deformation of the bonding jig 1, local accumulation of materials occurs after the bonding jig 1 is squeezed, the overall structure of the one-piece bonding jig 1 has no difference or little difference, and the pressure of the arc corner part is quite different from that of the center part, which causes a gap between the screen and the cover plate, or the cover plate and the screen cannot be tightly attached together, affecting the quality of the screen and causing problems such as bonding bubbles.

[0064] Based on this, the present application provides a bonding fixture solution to make the bonding tighter, reduce the bubbles between the screen and the cover plate, and ensure the quality of the screen.

[0065] Reference Figure 2 , Figure 3 As shown, a bonding jig provided in an embodiment of the present application is used to bond a screen body to a cover plate to form a curved screen. The bonding jig 1 includes a jig body 11 and an auxiliary part 12. The jig body 11 includes a support surface 10 for supporting the part to be bonded. The support surface 10 includes a plane area 101 and an arc angle area 102. The arc angle area 102 is arranged around the plane area 101. The auxiliary part 12 is connected to the jig body 11, and the modulus of the auxiliary part 12 is smaller than the modulus of the jig body 11. The orthographic projection of the auxiliary part 12 on the support surface 10 is at least located in the arc angle area 102.

[0066] The modulus is the ratio of stress to strain of a material under load. A small modulus means that the material will produce a larger strain under the same stress. In other words, a small modulus means it is easier to deform.

[0067] Specifically, the orthographic projection on the support surface 10 refers to the projection onto the plane where the plane area 101 of the support surface 10 is located, or the projection onto the arc surface where the arc angle area 102 is located. Among them, the orthographic projection of the auxiliary part 12 on the support surface 10 can be all located in the arc angle area 102, or the orthographic projection of the auxiliary part 12 on the support surface 10 is distributed in the plane area 101 and the arc angle area 102. That is, at least the peripheral part of the fixture body 11 corresponding to the arc angle area 102 is provided with an auxiliary part 12, and the central part corresponding to the plane area 101 is optionally provided with an auxiliary part 12. The material of the auxiliary part 12 can be silicone.

[0068] In the bonding jig provided in the present application, by setting an auxiliary part 12 with a smaller modulus on the jig body 11, at least the elasticity of the area where the auxiliary part 12 is located can be adjusted. During the bonding process of the screen body and the cover plate, the deformation of the area where the auxiliary part is set in the jig body 11 will increase, which can reduce local accumulation of materials and make the pressure distribution of various parts of the jig body 11 more balanced, thereby adjusting the bonding pressure of the jig body 11 on the parts to be bonded, meeting the bonding requirements, improving the bonding quality of the screen body and the cover plate, and improving the product yield.

[0069] Reference Figure 3 As shown, in one embodiment, the auxiliary member 12 includes a first auxiliary member 121 and a second auxiliary member 122, the orthographic projection of the first auxiliary member 121 on the plane where the support surface 10 is located is at least located in the plane area 101, and the orthographic projection of the second auxiliary member 122 on the plane where the support surface 10 is located is at least located in the arc angle area 102. Specifically, the first auxiliary member 121 is mainly distributed in the plane area 101, and can also partially extend to the arc angle area 102, and the second auxiliary member 122 is arranged in the arc angle area 102. Among them, the modulus of the first auxiliary member 121 and the second auxiliary member 122 are different; and / or, the shapes of the first auxiliary member 121 and the second auxiliary member 122 are different; and / or, the number of the first auxiliary member 121 and the second auxiliary member 122 is different.

[0070] Among them, different first auxiliary parts 121 and second auxiliary parts 122 are arranged in different fitting areas of the fixture body 11 to form a differentiated design, which can adjust the fitting pressure on the screen body and further meet the needs of fitting pressure in different areas of the screen body.

[0071] Reference Figure 3 As shown, in one embodiment, the support surface 10 includes a support plane 111 and a support arc surface 112, and part of the support plane 111 is located in the plane area 101 and part of it is located in the arc angle area 102. The support arc surface 112 is located in the arc angle area 102. The first auxiliary component 121 includes a first surface close to one side of the support surface 10, and the first surface is parallel to the support plane 111. The second auxiliary component 122 includes a second surface close to one side of the support surface 10, wherein the second surface may include a plane and / or an arc surface. For example, the second surface is a plane and is parallel to the section of the support arc surface 112. The section of the support arc surface 112 refers to the section of the support point on the support arc surface 112. For example, the second surface is an arc surface and is arranged at an equal distance from the support arc surface 112. For example, the second surface includes both an arc surface and a plane, wherein the plane part is parallel to the section of the support arc surface 112, and the arc surface part is arranged at an equal distance from the support arc surface 112. Among them, the spacing between the two curved surfaces arranged at equal intervals is unchanged, and the direction and degree of bending are the same, which can correspond to the contour design.

[0072] Specifically, taking the side close to the supporting surface 10 as the top side, the top surface of the first auxiliary component 121 is parallel to the supporting plane 111, and the top surface of the second auxiliary component 122 is parallel to the tangent plane of a certain supporting point of the supporting arc surface 112, so that the top of the first auxiliary component 121 and the second auxiliary component 122 are basically consistent with the force direction of the corresponding supporting surface 10, ensuring that the direction of the bonding force on the screen body is roughly perpendicular to the direction of the supporting surface 10.

[0073] Optionally, refer to Figure 4As shown, the second auxiliary member 122 includes a first portion 1221 and a second portion 1222, the second portion 1222 is located on the side of the first portion 1221 away from the support surface 10, and the cross-sectional area of ​​the first portion 1221 is smaller than the cross-sectional area of ​​the second portion 1222, that is, the second auxiliary member 122 has a "convex" cross-sectional area. The second auxiliary member 122 adopts a trapezoidal structure with a small top and a large bottom, which can correspond to the arc angle shape of the arc angle area 102, ensuring that the direction of the bonding force meets the bonding requirements.

[0077] Optionally, a plurality of first auxiliary parts 121 are provided, and the plurality of first auxiliary parts 121 are arranged in an array. For example, in the fixture body 11, the plurality of first auxiliary parts 121 can be arranged in a matrix on a plane parallel to the support plane 111, or can form a three-dimensional dot matrix arrangement in space. Among them, the plurality of first auxiliary parts 121 can be evenly distributed inside the fixture body 11, or can be irregularly designed according to the actual fitting conditions. For example, in areas with tighter fitting, the auxiliary parts are distributed sparsely, and in areas with looser fitting, the auxiliary parts are distributed densely, or the distribution of the auxiliary parts can be designed with other different gradients.

[0078] Optionally, the second auxiliary member 122 extends longitudinally along the second direction.

[0079] Specifically, along the longitudinal extension direction of the fixture body 11 , the second auxiliary member 122 is a whole strip structure, and the first auxiliary member 121 is a multi-segment strip structure.

[0080] Preferably, the first direction is perpendicular to the second direction.

The direction parallel to the support surface 10 includes a direction parallel to the support plane 111 or a direction parallel to the tangent plane of the support arc surface 112.

[0082] Optionally, the matching groove 113 is adapted to the shape of the corresponding auxiliary component 12 .

[0083] Among them, the size of the matching groove 113 is larger than the auxiliary part 12. The matching groove 113 can accommodate the auxiliary part 12. At the same time, during the extrusion and bonding process, the matching groove 113 can also provide a space for material deformation, which can reduce material accumulation to a certain extent, ensure the bonding area, and provide sufficient bonding pressure.

[0084] Reference Figure 6 As shown, in one embodiment, the fixture body 11 includes a central portion 1010 and a peripheral portion 1020, the peripheral portion 1020 is connected to the periphery of the central portion 1010, the central portion 1010 includes a plane area 101, and the peripheral portion 1020 includes an arc angle area 102.

[0085] Among them, the fixture body 11 adopts a split design, and part or all of the structure in the peripheral part 1020 can be replaced without changing the central part 1010 to support screens with different arc angles, which can meet interchangeability, facilitate design changes, and reduce cost waste.

[0086] Optionally, the first sub-section 1021 and the third sub-section 1023 are arranged at intervals along the second direction, and the second direction is the longitudinal extension direction of the fixture body 11.

The first auxiliary member 121 and the second auxiliary member 122 are columnar structures and are designed to be perpendicular to the support surface 10, which can ensure that the direction of the bonding force on the screen body meets the requirements.

[0089] Optionally, the first receiving groove 1131 matches the shape of the first auxiliary member 121, and the second receiving groove 1132 matches the shape of the second auxiliary member 122. The first receiving groove 1131 and the first auxiliary member 121, the second receiving groove 1132 and the second auxiliary member 122 are all "convex" structures.

[0090] Optionally, in a direction parallel to the support surface 10, the size of the first receiving groove 1131 is larger than the size of the first auxiliary member 121, and the size of the second receiving groove 1132 is larger than the size of the second auxiliary member 122. The first receiving groove 1131 and the second receiving groove 1132 can provide receiving space for the first auxiliary member 121 and the second auxiliary member 122, respectively, and can also provide additional space for material deformation of the auxiliary members.

[0097] Specifically, the base 13 is an elastic member, and its material can be a highly elastic material such as silicone or rubber. The fixture body 11 is a sheet-like structure, and the connecting surface 131 is the same shape as the support surface 10, and forms a uniform spacing. The bottoms of the first auxiliary member 121 and the second auxiliary member 122 are in contact with the connecting surface 131, and the first auxiliary member 121 and the second auxiliary member 122 pass through the fixture body 11. During the bonding process, the first auxiliary member 121, the second auxiliary member 122 and the fixture body 11 jointly provide bonding force to the piece to be bonded on the support surface 10.

[0099] Specifically, a groove is dug downward or a blind hole is opened on the support surface 10 to form an auxiliary groove 123, which can provide a receiving groove for material deformation. An upwardly protruding auxiliary protrusion 124 is provided in the arc angle area 102 of the support surface 10 to prevent insufficient elastic support of the fixture body 11 after the groove is dug. At the same time, the fitting force of different fitting areas of the fixture body 11 can be adjusted.

[0100] Optionally, a plurality of auxiliary grooves 123 are provided, and the orthographic projections of the plurality of auxiliary grooves 123 on the support surface 10 are located in the plane area 101 and the arc angle area 102. The auxiliary grooves 123 are provided in both the plane area 101 and the arc angle area 102, and the auxiliary grooves 123 can be evenly distributed in the plane area 101 and the arc angle area 102, or can be arranged differently according to the requirements for fitting different areas of the cover plate and the screen body.

[0101] Optionally, the cross-sectional area of ​​the auxiliary groove 123 close to the support surface 10 is smaller than the cross-sectional area of ​​the part away from the support surface 10. The auxiliary groove 123 adopts a blind hole structure with a small top and a large bottom, which can ensure a larger contact area and provide more accommodation space for material compression deformation.

[0102] Optionally, the shape of the cross section of the auxiliary groove 123 includes a semicircle or an inverted trapezoid.

[0103] Optionally, the cross-sectional shape of the auxiliary protrusion 124 includes a semicircular shape or a triangular shape;

[0104] Optionally, the shape of the orthographic projection of the auxiliary groove 123 on the support surface 10 includes at least one of a triangle, a circle or a square.

[0105] Optionally, in a direction perpendicular to the support surface 10 , the depth of the auxiliary groove 123 is less than half of the thickness of the jig body 11 .

[0106] Optionally, in a direction perpendicular to the support surface 10 , the depth of the auxiliary groove 123 is less than 5 mm.

[0107] Optionally, in a direction perpendicular to the support surface 10 , the height of the auxiliary protrusion 124 is less than 5 mm.

[0108] Another embodiment of the present application provides a laminating device, which includes the laminating jig 1 in the above embodiment. The laminating device can be used to laminarize a flexible screen body onto a curved cover plate to form a curved screen.

[0109] The bonding device provided in the present application has a bonding jig 1 in which an auxiliary part 12 with a smaller modulus is provided on the jig main body 11, so that at least the elasticity of the area where the auxiliary part 12 is located can be adjusted. During the bonding process of the screen body and the cover plate, the deformation of the area where the auxiliary part is provided in the jig main body 11 will increase, which can reduce local accumulation of materials and make the pressure distribution of various parts of the jig main body 11 more balanced, thereby adjusting the bonding pressure of the jig main body 11 on the part to be bonded, meeting the bonding requirements, improving the bonding quality of the screen body and the cover plate, and improving the product yield.
