It is understood that at least one of the first clamping mechanism 41 and the second clamping mechanism 42 is configured to be movable relative to the first abutting member 101, and the following schemes may be included: 1. the first clamping mechanism 41 is configured to be movable relative to the first abutment member 101; 2. the second clamping mechanism 42 is configured to move relative to the first abutment member 101; 3. the first clamping mechanism 41 and the second clamping mechanism 42 are both configured to be movable relative to the first abutment member 101.

Furthermore, in some embodiments, at least one of the first clamping mechanism 41 and the second clamping mechanism 42 comprises a reel, the carrier 1 is wound on the reel, and at least one of the first clamping mechanism 41 and the second clamping mechanism 42 is configured to move relative to the first fitting member 101, so that the tension of the carrier 1 is substantially constant during the fitting process.

In some embodiments of the present invention, the supporting member 1 is adapted to be separable from the second attaching member 102, and after the first attaching member 101 and the second attaching member 102 are attached, the supporting member 1 is separated from the second attaching member 102, so as to avoid the supporting member 1 from affecting the first attaching member 101 and the second attaching member 102, and meanwhile, a requirement that a side surface of the second attaching member 102 facing away from the first attaching member 101 needs to be attached to other components can be met, so that the applicability of the attaching device 100 is effectively improved.

In some embodiments of the present invention, the first attaching member 101 is a cover plate, and the second attaching member 102 is a flexible display screen, in which case the attaching device 100 can be used for attaching the cover plate to the flexible display screen, and the flexible display screen can be attached to the back side of the cover plate, so that the cover plate can protect the flexible display screen and prevent the flexible display screen from being easily damaged. Optionally, the cover plate is a glass cover plate.

It should be noted that in the description of the present application, the "back side" of the component may refer to the side of the component facing away from the user.

Of course, the present application is not so limited; in other embodiments, the first fitting member 101 is a display screen, and the second fitting member 102 is a flexible film, in which case the fitting apparatus 100 can be used for fitting the display screen and the flexible film, and the flexible film can be fitted on the back side of the display screen. Alternatively, the flexible film may be a heat dissipation film or the like.

In some embodiments of the present invention, as shown in fig. 3, the first abutting member 101 is formed in a cylindrical structure, such as a cylindrical structure, an elliptic cylindrical structure, or the like, where the cross-sectional shape of the first abutting member 101 is a closed ring shape, and the cylindrical surface 101a is an inner circumferential wall of the first abutting member 101.

For example, in the example of fig. 3 to 6, the first fitting member 101 is a cover plate and has a cylindrical structure, the cylindrical surface 101a is formed as a straight cylindrical surface, the second fitting member 102 is a flexible display screen such as an OLED display screen, and the second fitting member 102 is fitted to the cylindrical surface 101 a. The cylindrical surface 101a has a fitting region, the area of the fitting region is smaller than the surface area of the cylindrical surface 101a, and the second fitting member 102 is fitted in the fitting region.

Other configurations and operations of the attaching device 100 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.

Next, a bonding method according to an embodiment of the present invention is described with reference to the drawings. The bonding method uses the bonding apparatus 100 according to the first embodiment of the present invention to perform bonding.

As shown in fig. 7 and 8, the attaching method includes:

s1, the second engaging member 102 is disposed on the supporting member 1, the clamping member 4 clamps the two opposite ends of the supporting member 1, and the first engaging member 101 is sleeved on the outer sides of the second engaging member 102, the supporting member 1 and the clamping member 4. For example, the second applying member 102 may be adhered to a thickness side surface of the carrier 1, when the clamping assembly 4 clamps the carrier 1, the clamping assembly 4 and the carrier 1 may be formed substantially in a closed ring structure, in which case the first applying roller 2 and the second applying roller 3 may both be located on a side of the carrier 1 facing away from the second applying member 102, that is, the first applying roller 2 and the second applying roller 3 may both be located on an inner side of the carrier 1, so that the first applying roller 2 and the second applying roller 3 may play a certain supporting role on the carrier 1.

S2, one of the first applying roller 2 and the second applying roller 3 is in a force applying position, the other is in an avoiding position, and the clamping assembly 4 tightens the carrier 1 so that the carrier 1 is tensioned among the first applying roller 2, the second applying roller 3 and the clamping assembly 4, and at this time, the carrier 1 has a proper tension. Wherein, in the application position, above-mentioned one in first laminating roller 2 and the second laminating roller 3 applys effort to carrying thing 1 so that the border of first laminating portion 102a or second laminating portion 102b laminates in cylinder 101a, and in the position of dodging, the radial distance between another in first laminating roller 2 and the second laminating roller 3 and cylinder 101a is greater than the sum of carrying thing 1 and the thickness of second laminating piece 102.

For example, as shown in fig. 3, step S2 may be: the first attaching roller 2 is located at a force application position, at this time, the first attaching roller 2 applies an acting force to the bearing piece 1 so that the edge of the first attaching portion 102a or the second attaching portion 102b is attached to the cylindrical surface 101a, or the radial distance between the first attaching roller 2 and the cylindrical surface 101a is short so that the first attaching roller 2 can apply pressure to the bearing piece 1, the second attaching roller 3 is located at an avoiding position, at this time, the radial distance between the second attaching roller 3 and the cylindrical surface 101a is larger so that the second attaching roller 3 cannot apply pressure to the first attaching piece 101, and the clamping assembly 4 tightens the bearing piece 1 so that the bearing piece 1 is tensioned among the first attaching roller 2, the second attaching roller 3 and the clamping assembly 4. Or step S2 is: the second laminating roller 3 is located at a force application position, the first laminating roller 2 is located at an avoiding position, and the clamping component 4 tightens the bearing part 1 so that the bearing part 1 is tensioned among the first laminating roller 2, the second laminating roller 3 and the clamping component 4.

One of the first application roller 2 and the second application roller 3 rolls in the circumferential direction of the cylindrical surface 101a, and the other is kept stationary at S3.

For example, as shown in fig. 3 to 5, in step S2, the first applying roller 2 is in the force application position, and the second applying roller 3 is in the retracted position, then in step S3, the first applying roller 2 rolls along the circumferential direction of the cylindrical surface 101a to gradually apply the first applying portion 102a to the cylindrical surface 101a, the second applying roller 3 remains stationary, that is, the position of the second applying roller 3 is always at the current position, and the second applying roller 3 can rotate at the current position along with the movement of the first applying roller 2 along the circumferential direction of the cylindrical surface 101a, so as to adapt to the adjustment of the tension of the carrier 1 by the clamping assembly 4. Or, in step S2, the second applying roller 3 is in the force application position, and the first applying roller 2 is in the avoiding position, then in step S3, the second applying roller 3 rolls along the circumferential direction of the cylindrical surface 101a to gradually apply the second applying portion 102b to the cylindrical surface 101a, the first applying roller 2 remains stationary, that is, the position of the first applying roller 2 is always at the current position, and the first applying roller 2 can rotate at the current position along with the movement of the second applying roller 3 along the circumferential direction of the cylindrical surface 101a, so as to adapt to the adjustment of the tensioning force of the clamping assembly 4 to the carrier 1.

S4, the other of the first application roller 2 and the second application roller 3 rolls in the circumferential direction of the cylindrical surface 101a until the second application member 102 is applied to the first application member 101.

For example, as shown in fig. 5 and 6, when the first bonding roller 2 is in the biasing position and the second bonding roller 3 is in the retracted position in step S2, the first bonding portion 102a may be bonded to the cylindrical surface 101a in step S3, and at this time, in step S4, the second bonding roller 3 rolls in the circumferential direction of the cylindrical surface 101a to gradually bond the second bonding portion 102b to the cylindrical surface 101a until the entire second bonding member 102 is bonded to the first bonding member 101. Alternatively, in step S2, when the second bonding roller 3 is in the biasing position and the first bonding roller 2 is in the retracted position, the second bonding portion 102b may be bonded to the cylindrical surface 101a in step S3, and at this time, in step S4, the first bonding roller 2 rolls in the axial direction of the cylindrical surface 101a to gradually bond the first bonding portion 102a to the cylindrical surface 101a until the entire second bonding member 102 is bonded to the first bonding member 101.

It should be noted that, the steps may have a sequence, and the sequence of each action in the same step is not fixed. For example, step S1, step S2, step S3, and step S4 are sequentially performed, such that "the two opposite ends of the carrier 1 are clamped by the clamping assembly 4" in step S1 is located before "the carrier 1 is tightened by the clamping assembly 4" in step S2, and in step S1, the sequence of "the second engaging member 102 is disposed on the carrier 1", "the clamping assembly 4 clamps the two opposite ends of the carrier 1", and "the first engaging member 101 is sleeved on the outer sides of the first engaging member 101, the carrier 1, and the clamping assembly 4" is not fixed, and the second engaging member 102 may be disposed on the carrier 1, the clamping assembly 4 clamps the two opposite ends of the carrier 1, and then the first engaging member 101 is sleeved on the outer sides of the second engaging member 102, the carrier 1, and the carrier assembly 4; but is not limited thereto.

Therefore, according to the attaching method of the embodiment of the invention, the second attaching member 102 can be flatly and closely attached to the inner surface of the first attaching member 101, so that the first attaching member 101 protects the second attaching member 102, and meanwhile, in the attaching process, the clamping assembly 4 clamps the bearing member 1 to realize profiling of the second attaching member 102, so that damage to the second attaching member 102 and the like can be avoided.

It is to be understood that, in step S2, when one of first applying roller 2 and second applying roller 3 is in the urging position and the other is in the retracted position, there is no gap or space between first applying roller 2 and second applying roller 3.

In some embodiments of the present invention, the clamping assembly 4 comprises a reel, and in steps S3 and S4, the carrier 1 is unwound from the reel to ensure that the tension of the carrier 1 is kept substantially constant during the attaching process by increasing the length of the carrier 1 in the circumferential direction of the cylindrical surface 101a, so as to ensure the attaching effect of the second attaching member 102 and the first attaching member 101.

Of course, the structure of the clamp assembly 4 is not limited thereto; the clamping assembly 4 may also be configured such that one end of the clamping member 1 is movable relative to the first abutment member 101, which also ensures that the tension of the carrier member 1 remains substantially constant during the abutment process.

In some embodiments of the present invention, in step S4, the other one of the first applying roller 2 and the second applying roller 3 moves to the force applying position in step S2 and then rolls along the circumferential direction of the cylindrical surface 101a, so that the problem of poor applying of the first applying member 101 and the second applying member 102, such as bubbles, generated in the portion between the first applying roller 2 and the second applying roller 3 can be avoided, and the applying effect of the first applying member 101 and the second applying member 102 can be further ensured.

For example, if the first bonding roller 2 is in the biased position and the second bonding roller 3 is in the retracted position in step S2, the first bonding portion 102a may be bonded to the cylindrical surface 101a in step S3, and in this case, in step S4, the second bonding roller 3 moves to the biased position where the first bonding roller 2 is located in step S2 and then rolls in the circumferential direction of the cylindrical surface 101a, and the moving direction of the second bonding roller 3 is opposite to the moving direction of the first bonding roller 2. Alternatively, if the second bonding roller 3 is in the biasing position and the first bonding roller 2 is in the retracted position in step S2, the second bonding portion 102b may be bonded to the cylindrical surface 101a in step S3, and in this case, in step S4, the first bonding roller 2 moves to the biasing position where the second bonding roller 3 is located in step S2 and rolls in the circumferential direction of the cylindrical surface 101 a.

Of course, if the other of the first application roller 2 and the second application roller 3 is not moved to the force application position in step S2 in advance in step S4, the application effect of the portions of the first application member 101 and the second application member 102 between the first application roller 2 and the second application roller 3 may be ensured in other ways.

Optionally, in step S4, the first applying roller 2 and the second applying roller 3 are kept stationary, so as to ensure that the first applying portion 102a or the second applying portion 102b applied to the cylindrical surface 101a is stably applied to the cylindrical surface 101a, reduce the acting force applied to the first applying portion 102a or the second applying portion 102b applied to the cylindrical surface 101a, and ensure the applying effect of the first applying member 101 and the second applying member 102.

In some embodiments of the present invention, as shown in fig. 8, the carrier 1 is configured to be detachable from the second fitting 102, and the fitting method further includes: s5, after the second attaching member 102 is attached to the first attaching member 101, the bearing member 1 is separated from the second attaching member 102, so as to avoid the bearing member 1 from affecting the first attaching member 101 and the second attaching member 102, and meet a requirement that a side surface of the second attaching member 102 facing away from the first attaching member 101 needs to be attached to other components.

For example, when the first attaching member 101 is a cover plate and the second attaching member 102 is a flexible display screen, the supporting member 1 is separated from the second attaching member 102, and a surface of the second attaching member 102 opposite to the first attaching member 101 may be attached with other film materials such as a heat dissipation film, so as to better meet the actual differentiation requirement; when first laminating 101 is the display screen, second laminating 102 is the flexible membrane, other membrane materials such as buffer layer, flat layer can be laminated to the side surface of second laminating 102 that is dorsad first laminating 101 to better satisfy actual differentiation demand.

It is understood that, in step S5, after the first engaging member 101 and the second engaging member 102 are engaged, the supporting member 1 may be released from the clamping assembly 4 and then the supporting member 1 is separated from the second engaging member 102, or the supporting member 1 may be separated from the second engaging member 102 and then the clamping assembly 4 is released from the supporting member 1.

In some embodiments, in step S5, before separating the carrier 1 from the second adhesive member 102, ultraviolet rays are used to irradiate (UV irradiates) a side surface of the carrier 1 facing away from the second adhesive member 102, that is, the inner side surface of the carrier 1 is irradiated with ultraviolet rays, so as to reduce the viscosity between the carrier 1 and the second adhesive member 102, so as to facilitate the carrier 1 to be torn away from the second adhesive member 102 quickly, improve the efficiency of the whole adhering process, and simultaneously avoid the carrier 1 from damaging the second adhesive member 102 during the tearing away process.
