Fig. 1 is a schematic working diagram of a flexible screen attaching device according to an embodiment of the present application, and fig. 2 is a schematic working diagram of another flexible screen attaching device according to an embodiment of the present application.
As shown in fig. 1 and 2, the flexible screen attaching device provided in the embodiment of the application is used for attaching the flexible screen 10 to the first structure 20.
The flexible screen attaching device 30 provided by the embodiment of the application comprises a first mechanism 31 and a second mechanism 32, wherein the first mechanism 31 and the second mechanism 32 are used for clamping the flexible screen 10 and the first structure 20. That is, the first mechanism 31 and the second mechanism 32 of the flexible screen attaching device 30 apply a clamping force to the flexible screen 10 and the first structure 20 during the attaching of the flexible screen 10 and the first structure 20. A gap exists between the first mechanism 31 and the second mechanism 32, and the flexible screen 10 and the first structure 20 pass through the gap; the flexible screen 10 and the first structure 20 passing through the gap are pressed by the first mechanism 31 and the second mechanism 32 on both sides of the gap, and the portion of the flexible screen 10 and the first structure 20 in the gap is attached.
In the process of attaching the flexible screen 10 to the first structure 20 by the flexible screen attaching device 30, the first mechanism 31 drives the second mechanism 32 to move, and the first mechanism 31 and the second mechanism 32 move in the same direction relative to the flexible screen 10 and the first structure 20. That is, during the process of attaching the flexible screen 10 to the second structure 20, the first mechanism 31 in the flexible screen attaching device 30 applies traction to the second mechanism 32, and the first mechanism 31 moves to drive the second mechanism 32 to move simultaneously. When the first mechanism 31 starts to move in one direction from the starting point in the process of attaching the flexible screen 10 to the second structure 20, the corresponding second mechanism 32 starts to move in the one direction from the starting point, at this time, the clamping positions of the first mechanism 31 and the second mechanism 32 on the flexible screen 10 and the first structure 20 are changed, and the positions of the flexible screen 10 and the first structure 20 clamped by the first mechanism 31 and the second mechanism 32 are attached.
For example, as shown in fig. 1 and 2, in the process of attaching the flexible screen 10 to the first structure 20, the starting points of the first mechanism 31 and the second mechanism 32 are at the intermediate position between the flexible screen 10 and the first structure 20. When the first mechanism 31 moves leftwards from the intermediate position, the second mechanism 32 is simultaneously driven by the first mechanism 31 to move leftwards from the intermediate position, and the flexible screen 10 is attached to the position of the first structure 20 clamped by the first mechanism 31 and the second mechanism 32.
In the embodiment of the present application, the first mechanism 31 in the flexible screen laminating device 30 can drive the second mechanism 32 to move, so that the first mechanism 31 and the second mechanism 32 can apply pressure to the same laminating position of the flexible screen 10 and the first structure 20 substantially simultaneously, thereby ensuring the laminating strength of the flexible screen laminating device 30. In addition, in the process of attaching the flexible screen 10 and the first structure 20, the first mechanism 31 drives the second mechanism 32 to move, so that the linkage between the first mechanism 31 and the second mechanism 32 is enhanced, the movement path of the second mechanism 32 is basically the same as that of the first mechanism 31, and the two keep basically consistent attaching force to the flexible screen 10 and the first structure 20, so that wrinkles and bubbles are not generated in the attaching process of the flexible screen 10 and the first structure 20, and the attaching yield between the flexible screen 10 and the first mechanism 20 is improved.
In a corresponding embodiment of the present application, as shown in fig. 1, the first mechanism 31 is disposed on a side near the flexible screen 10, and the second mechanism 32 is disposed on a side near the first structure 20. That is, in the process of attaching the flexible screen 10 to the first structure 20, the first mechanism 31 is in contact with the flexible screen 10, and the second mechanism 32 is in contact with the first structure 20.
In another corresponding embodiment of the present application, as shown in fig. 2, the first mechanism 31 is disposed on a side near the first structure 20, and the second mechanism 32 is disposed on a side near the flexible screen 10. That is, in the process of attaching the flexible screen 10 to the first structure 20, the first mechanism 31 is in contact with the first structure 20, and the second mechanism 32 is in contact with the flexible screen 10.
In one embodiment of the present application, the flexible screen fitting device 30 may fit the flexible screen 10 with a curved rigid structure, that is, the first structure 20 in the fitting object of the flexible screen fitting device 30 may be a curved rigid structure. For example, the first structure 20 is a curved glass cover plate.
When the first structure 20 is a curved rigid structure, at least a portion of the first structure 20 has a bending curvature. For example, when the first structure 20 is a curved glass cover plate, as shown in fig. 1 and 2, at least two sides of the first structure 20 have a certain curvature.
In the prior art, a jig for attaching a flexible screen to a curved glass cover plate is usually that a pressing mechanism is in contact with the flexible screen, the pressing mechanism presses the flexible screen to the inner side of the fixed curved glass cover plate, and the pressing mechanism moves along the inner side of the curved glass cover plate so that the flexible screen is integrally attached to the curved glass cover plate. However, the pressing force of the pressing mechanism in the prior art on the flexible screen is continuously changed along with the friction force and time. In particular, the side edge of the curved glass cover plate has a certain curvature, and when the pressing mechanism moves from the flat position corresponding to the curved glass cover plate to the side edge of the curved glass cover plate, the attaching pressure of the pressing mechanism to the flexible screen can be influenced when the moving direction of the pressing mechanism changes. Therefore, in the prior art, the yield of the side lamination of the flexible screen and the curved glass cover plate is low, and the situations of incomplete lamination, air bubbles and wrinkles usually exist.
According to the flexible screen attaching device 30 provided by the embodiment of the application, the flexible screen 10 can be attached to the first structure 20 with a curved rigid structure, and in the process of attaching the flexible screen 10 to the curved portion of the first structure 20, as the first mechanism 31 and the second mechanism 32 still act on the flexible screen 10 and the first structure 20 corresponding to the curved portion at the same time, the attaching pressure of the first mechanism 31 and the second mechanism 32 to the flexible screen 10 and the curved portion of the first structure 20 is basically kept consistent, so that the attaching yield of the flexible screen 10 and the first structure 20 with a curved rigid structure is improved.
In an embodiment of the present application, as shown in fig. 1 and 2, the first mechanism 31 and the second mechanism 32 are rollers, and the movement modes of the first mechanism 31 and the second mechanism 32 may be rolling modes. On the one hand, the contact areas of the first mechanism 31 and the second mechanism 32 with the flexible screen 10 and the first structure 20 are reduced, and the pressing force of the first mechanism 31 and the second mechanism 32 on the flexible screen 10 and the first structure 20 is increased; on the other hand, when the first mechanism 31 and the second mechanism 32 move to attach the flexible screen 10 and the first structure 20 to different positions, friction damage of the first mechanism 31 and the second mechanism 32 to the flexible screen 10 and the second structure 20 is avoided.
In the present embodiment, the first mechanism 31 is parallel to the rolling axis of the second mechanism 32 in the process of attaching the flexible screen 10 to the first structure 20. The bonding pressure to the flexible screen 10 and the first structure 20 is substantially uniform during the rolling of the first mechanism 31 and the second mechanism 32.
Fig. 3 is a schematic working diagram of a flexible screen attaching device according to another embodiment of the present application, and fig. 4 is a schematic working diagram of another flexible screen attaching device according to another embodiment of the present application.
In one embodiment of the present application, the flexible screen fitting device further comprises a third mechanism 31 'and a fourth mechanism 32', wherein the third mechanism 31 'and the fourth mechanism 32' are used for clamping the flexible screen 10 and the first structure 20. That is, in the process of attaching the flexible screen 10 to the first structure 20, a gap is also present between the third mechanism 31 'and the fourth mechanism 32' of the flexible screen attaching device 30, and the flexible screen 10 and the first structure 20 pass through the gap; the flexible screen 10 and the first structure 20 passing through the gap are pressed by the third mechanism 31 'and the fourth mechanism 32' on both sides of the gap, and the portion of the flexible screen 10 and the first structure 20 in the gap is attached.
In the process of attaching the flexible screen 10 to the first structure 20, the third mechanism 31 'drives the fourth mechanism 32' to move, and the third mechanism 31 'and the fourth mechanism 32' move in the same direction with the first structure 20 relative to the flexible screen 10. That is, during the process of attaching the flexible screen 10 to the second structure 20, the third mechanism 31 'in the flexible screen attaching device 30 applies traction to the fourth mechanism 32', and the third mechanism 31 'moves to drive the fourth mechanism 32' to move simultaneously. When the third mechanism 31 'starts to move in one direction from the starting point during the process of attaching the flexible screen 10 to the second structure 20, the corresponding fourth mechanism 32' starts to move in the one direction from the starting point, at this time, the clamping positions of the third mechanism 31 'and the fourth mechanism 32' on the flexible screen 10 and the first structure 20 are changed, and the positions of the flexible screen 10 and the first structure 20 clamped by the third mechanism 31 'and the fourth mechanism 32' are attached.
In the present embodiment, in the process of attaching the flexible screen 10 to the first structure 20, the movement directions of the first mechanism 31, the second mechanism 32, and the third mechanism 31', the fourth mechanism 32' are different. For example, as shown in fig. 3 and 4, in the process of attaching the flexible screen 10 to the first structure 20, the first mechanism 31 and the second mechanism 32 move leftward from the intermediate position between the flexible screen 10 and the first structure 20, and the third mechanism 31 'and the fourth mechanism 32' move rightward from the intermediate position between the flexible screen 10 and the first structure 20.
It will be appreciated that the flexible screen fitting device 30 provided in this embodiment includes at least two sets of fitting mechanisms, wherein one set of fitting mechanisms includes a first mechanism 31 and a second mechanism 32, and the other set of fitting mechanisms includes a third mechanism 31 'and a fourth mechanism 32'. The at least two groups of laminating mechanisms can respectively laminate different positions of the flexible screen 10 and the first structure 20 in the laminating process of the flexible screen 10 and the first structure 20, so that the laminating efficiency of the flexible screen laminating device on the flexible screen 10 and the first structure 20 is improved.
The first mechanism 31 and the third mechanism 31' may not have a connection relationship, that is, the movement distance between the two mechanisms is not limited by each other, so that the application scene of the flexible screen laminating device 30 is not limited while the laminating efficiency is increased, that is, the application scene is not limited. The flexible screen attaching device 30 provided in this embodiment may be suitable for attaching flexible screens 10 and first structures 20 of different shapes and sizes.
It should be noted that the third mechanism 31 'and the first mechanism 31 may be located on the same side and the fourth mechanism 32' and the second mechanism 32 may be located on the same side.
For example, as shown in fig. 3, the first structure 31 and the third mechanism 31 'are both disposed on a side near the flexible screen 10, and the second mechanism 32 and the fourth mechanism 32' are both disposed on a side near the first structure 20. That is, in the process of bonding the flexible screen 10 and the first structure 20, the first mechanism 31 and the third mechanism 31 'are in contact with the flexible screen 10, and the second mechanism 32 and the fourth mechanism 32' are in contact with the first structure 20.
For example, as shown in fig. 4, the first structure 31 and the third structure 31 'are both disposed on a side near the first structure 20, and the second structure 32 and the fourth structure 32' are both disposed on a side near the flexible screen 10. That is, in the process of bonding the flexible screen 10 and the first structure 20, the first mechanism 31 and the third mechanism 31 'are in contact with the first structure 20, and the second mechanism 32 and the fourth mechanism 32' are in contact with the flexible screen 10.
It should be further noted that the third mechanism 31' and the first mechanism 31 may have the same structure, for example, both are rollers; the fourth mechanism 32' and the second mechanism 32 may have the same structure, for example, both are rollers.

According to another technical scheme corresponding to the implementation manner, as shown in fig. 8, the second mechanism 32 is arranged on one side close to the flexible screen 10, the pressure sensor 33 is used for detecting the bonding pressure between the second mechanism 32 and the flexible screen 10, and the servo motor 34 controls the contact force between the second mechanism 32 and the flexible screen 10 according to the bonding pressure detected by the pressure sensor 33.

It should be further noted that, when the flexible screen attaching device 30 provided in the embodiment of the present application further includes the third mechanism 31 'and the fourth mechanism 32', the pressure sensor 33 may also be used to detect the attaching pressure of the third mechanism 31 'and/or the fourth mechanism 32' to the flexible screen 10 and the first structure 20, and the servo motor 34 is used to control the contact force between the third mechanism 31 'and/or the fourth mechanism 32' and the flexible screen 10/the first structure 20 according to the attaching pressure detected by the pressure sensor 33.
In addition, when the third mechanism 31' and the first mechanism 31 are provided on the same side, both can be controlled by the same servo motor; when the fourth mechanism 32 'is provided on the same side as the second mechanism 32', both can also be controlled by the same servo motor.

That is, there is a magnetic attraction between the first structure 31 and the second structure 32; the clamping force of the first mechanism 31 and the second mechanism 32 on the flexible screen 10 and the first structure 20 may be in the form of magnetic attraction.
In one implementation of the present embodiment, both the first mechanism 31 and the second mechanism 32 include magnets or electromagnets.
In another implementation of the present embodiment, one of the first mechanism 31 and the second mechanism 32 includes a magnet or an electromagnet, and the other includes a magneto-philic metal.
In one technical solution corresponding to the present embodiment, at least one of the first mechanism 31 and the second mechanism 32 includes an electromagnet; the magnetic attraction between the first mechanism 31 and the second mechanism 32 can be controlled by changing the current in the electromagnet.
Since the clamping force of the first mechanism 31 and the second mechanism 32 on the flexible screen 10 and the first structure 20 can be in the form of magnetic attraction, the contact force between the first mechanism 31 and the flexible screen 10 or the first structure 20 and the contact force between the second mechanism 32 and the first structure 20 or the flexible screen 10 can be controlled by changing the current flowing through the electromagnet in the process of attaching the flexible screen 10 and the first structure 20.

In this embodiment, when the flexible screen fitting device 30 further includes the third mechanism 31 'and the fourth mechanism 32', at least one of the third mechanism 31 'and the fourth mechanism 32' includes a magnet or an electromagnet, and during the fitting process of the flexible screen 10 and the first structure 20, the third mechanism 31 'drives the fourth mechanism 32' to move by magnetic attraction. The arrangement of the magnets or electromagnets in the third mechanism 31 'and/or the fourth mechanism 32' is the same as the arrangement of the magnets or electromagnets in the first mechanism 31 and/or the second mechanism 32, and will not be described herein.
In addition, when the third mechanism 31 'and the first mechanism 31 are disposed on the same side, the third mechanism 31' and the first mechanism 31 may have the same magnetic properties in the process of attaching the flexible screen 10 and the first structure 20, and the electromagnetic repulsive force therebetween may cause the two to move in opposite directions.

In one implementation of this embodiment, the length of the first portion 350 of the connector 35 between the first mechanism 31 and the second mechanism 32 is adjustable. The contact force between the first mechanism 31 and the flexible screen 10 or the first structure 20 and the contact force between the second mechanism 32 and the first structure 20 or the flexible screen 10 are controlled by changing the length of the first portion 350 in the process of attaching the flexible screen 10 and the first structure 20.
In one implementation, the first portion 350 is a portion of the connecting member 35 between the positions of the connecting member 35 to which the first and second mechanisms 31, 32 are fixed, and the first portion 350 may be a telescopic structure.
In a specific scheme, the servo motor 34 controls the clamping force of the first mechanism 31 and the second mechanism 32 on the flexible screen 10 and the first structure 20 by controlling the telescopic length of the first portion 350.
In another implementation, the positions on the connecting member 35 that are fixed to the first and second mechanisms 31, 32, respectively, may be adjusted, such that the length of the first portion 350 varies as the positions on the connecting member 35 that are fixed to the first and second mechanisms 31, 32, respectively, vary.
In a specific scheme, the servo motor 34 controls the clamping force of the first mechanism 31 and the second mechanism 32 on the flexible screen 10 and the first structure 20 by controlling the fixing positions of the first mechanism 31 and the second mechanism 32 and the connecting piece respectively.
In this embodiment, when the flexible screen fitting device 30 further includes the third mechanism 31 'and the fourth mechanism 32', the third mechanism 31 'and the fourth mechanism 32' are also connected by a connecting member. The connection means of the third mechanism 31 'and the fourth mechanism 32' may be the same as the connection means of the first mechanism 31 and the second mechanism 32, and will not be described herein.
