Fig. 1 is a schematic configuration diagram of a bonding apparatus according to an embodiment of the present application.
Based on this, embodiments of the present application provide a laminating apparatus for laminating a first object 3 and a second object 2 by an adhesive. As shown in FIG. 1, the attaching device may include an attaching member 4 having magnetism and a magnetic attracting member 1. Here, the magnetically attracting member 1 may be configured to attract the attaching member 4 by a magnetic force so that the attaching member 4 can apply a pressure to the first object 3. The attaching member 4 may also move on the surface of the first object 3 with the change of the direction of the magnetic force, so that the attaching of the first object 3 and the second object 2 is completed by the movement of the attaching member 4 and the pressing force of the attaching member 4 to the first object 3.
Specifically, when the magnetically attracting member 1 attracts the attaching member 4, the first object 3 and the second object 2 may be disposed between the magnetically attracting member 1 and the attaching member 4. Further, the attaching member 4 may be disposed on a side close to the first object 3, the magnetically attracting member 1 may be disposed on a side close to the second object 2, and the adhesive may be disposed between the first object 3 and the second object 2. Since the magnetic attraction member 1 has an attraction effect on the attaching member 4, the attaching member 4 applies a pressure to the first object 3 after the attaching member 4 comes into contact with the first object 3. Under the action of the pressure, the adhesive is pressed by the first object 3 and the second object 2, and the first object 3 and the second object 2 are attached to each other at the pressed positions. When the first object 3 and the second object 2 are pressed against the whole adhesive and the adhesive is in close contact with the first object 3 and the second object 2, the first object 3 and the second object 2 are attached to each other.
In order to achieve the pressing of the first object 3 and the second object 2 to the whole adhesive, the attaching member 4 may be moved on the surface of the first object 3, and the moving power of the attaching member 4 may be provided by the magnetic force between the magnetically attracting member 1 and the attaching member 4. Specifically, when the direction of the magnetic force between the magnetic attraction member 1 and the attaching member 4 is changed and the magnetic force is large enough to pull the attaching member 4 to move, the attaching member 4 will move on the surface of the first object 3 under the action of the magnetic force. Here, the magnetic force may power the movement of the attaching member 4 or may cause the attaching member 4 to apply pressure to the first object 3.
In the embodiment of the present application, the attaching member 4 may include a magnetic fluid having a certain fluidity so that the attaching member 4 can be freely moved on the surface of the first object 3 without being limited by space.
As mentioned above, the first object 3 may be a flexible screen, the second object 2 may be a cover plate, and the adhesive may be a double-sided optical adhesive disposed on the flexible screen. At the position of the R angle corresponding to the cover plate, the attaching part 4 can also apply pressure to the flexible screen and move at will, so that bubbles at the R angle are effectively avoided.
In an embodiment of the present application, the magnetic attraction component 1 may specifically include an electromagnet, and the magnetic attraction component 1 may attract the attachment component 4 through the electromagnet.
Specifically, in the embodiment of the present application, the magnetically attracting component 1 may include a permanent magnet or an electromagnet, and the embodiment of the present application is not limited to the type of the magnet included in the magnetically attracting component 1. When the magnetic part 1 comprises an electromagnet, the magnetic force between the magnetic part 1 and the attaching part 4 can be controlled by controlling the current of the electromagnet, so that the control of the magnetic force is more convenient. For example, when the magnetic force needs to be increased, the current of the electromagnet may be increased. Specifically, at the R angle, in order to further avoid the generation of bubbles, the current may be increased so as to increase the magnetic force between the magnetically attracting member 1 and the attaching member 4.
The embodiment of the application not only realizes the bonding of the first object 3 and the second object 2, but also effectively avoids the occurrence of bubbles caused by loose contact at the R corner of the second object 2 by arranging the bonding part 4 with magnetism and the magnetic attraction part 1 which is configured to attract the bonding part 4 through magnetic force, so that the bonding part 4 can apply pressure to the first object 3 and the bonding part 4 can move randomly on the surface of the first object 3 along with the change of the direction of the magnetic force.
In one embodiment of the present application, the attaching device may further include a driving part. Here, the driving member may drive the magnetically attracting member 1 to move so as to change the direction of the magnetic force by the movement of the magnetically attracting member 1.
Specifically, although the contact member 4 moves on the surface of the first object 3, the movement locus of the contact member 4 may be along the inner surface of the second object 2. Here, the inner surface of the second object 2 refers to a surface of the second object 2 that is in contact with the adhesive, and also refers to a surface of the second object 2 that is close to the first object 3. As shown in FIG. 1, conformable member 4 may be moved along the inner surface of second object 2 from an intermediate position of second object 2 towards one end 21 of second object 2. After the attaching member 4 moves to the one end 21, it can move to the other end 22 opposite to the one end 21, so that the whole adhesive can be pressed, and the attaching of the first object 3 and the second object 2 can be realized. Here, the number of times the attaching member 4 moves between the one end 21 and the other end 22 of the second object 2 may be more than one, and the number of times of movement is not limited in the embodiment of the present application.
Of course, the attaching member 4 may be moved from the one end 21 of the second object 2 to the other end 22 of the second object 2. Alternatively, the attaching member 4 may include a plurality of sub-members each of which moves on an area of the surface of the first object 3, and the plurality of sub-members move simultaneously, thereby achieving movement of the attaching member 4 over the entire surface of the first object 3. For example, the attaching member 4 may include two sub-members, and the two sub-members may move from opposite ends of the second object 2 to the middle, respectively, or the two sub-members may move from the middle of the second object 2 to both ends, respectively. The embodiment of the present application is not limited to the manner in which the attaching member 4 moves along the second object 2.
In addition, the movement of the magnetic attraction part 1 may be along the inner surface of the second object 2, or may not be along the inner surface of the second object 2, and the embodiment of the present application does not limit the movement track of the magnetic attraction part 1. Preferably, the magnetically attracting member 1 is movable along the inner surface of the second object 2, so that the magnitude of the magnetic force between the attaching member 4 and the magnetically attracting member 1 can be sufficiently stable.
For magnetic particles of the magnetic fluid, the uniform magnetic field only generates magnetic moments for the magnetic particles and does not generate moving component force for the magnetic particles. In order to move the magnetic particles, the magnetic force acting on the magnetic particles may be a function of the magnetic field and the magnetization of the magnetic force, as shown in the following formulas (1) and (2):
fmg＝0M▽H (1)
wherein f ismgIs the magnetic force per unit volume of the magnetic particles, M is the magnetization of the magnetic particles, H is the magnetic field strength, VparIs the volume of the magnetic particles and F is the magnetic force to which the magnetic particles are subjected.
The case where the attaching member 4 includes a plurality of sub-members is described below with reference to fig. 2.
Fig. 2a to 2c are schematic views illustrating a bonding process of a bonding apparatus according to an embodiment of the present application.
In one embodiment of the present application, as shown in fig. 2a, the magnetic attraction member 1 may include a first magnetic attraction unit 11 and a second magnetic attraction unit 12 arranged in parallel. Here, the preset moving track 111 of the first magnetic unit 11 and the preset moving track 121 of the second magnetic unit 12 may have a shape similar to the shape of the surface of the second object 2 close to the first object 3, so that the first magnetic unit 11 and the second magnetic unit 12 can move along the inner surface of the second object 2. When the first magnetic unit 11 and the second magnetic unit 12 are changed from contacting to separating, the attaching part 4 is separated into a first attaching unit 41 and a second attaching unit 42, the first attaching unit 41 moves along with the movement of the first magnetic unit 11, and the second attaching unit 42 moves along with the movement of the second magnetic unit 12. Similarly, when the first magnetic attraction unit 11 and the second magnetic attraction unit 12 are changed from being separated to being in contact with each other, the first attaching unit 41 and the second attaching unit 42 may also constitute the attaching member 4.
Specifically, the first magnetic unit 11 and the second magnetic unit 12 may be the same two units, or may be two different units, and the specification of the first magnetic unit 11 and the second magnetic unit 12 is not specifically limited in the embodiments of the present application. The first magnetic attraction unit 11 and the second magnetic attraction unit 12 may each include an electromagnet. Here, the above-mentioned parallel arrangement direction may refer to a direction parallel to the cross section shown in fig. 2 a. First magnetism is inhaled and can be had magnetic force between unit 11 and the laminating part 4, and second magnetism is inhaled and also can be had magnetic force between unit 12 and the laminating part 4, and first magnetism is inhaled and can be had magnetic force between unit 11 and the second magnetism and inhale unit 12, also can not have magnetic force, and the embodiment of this application is inhaled unit 11 and second magnetism and is inhaled whether to have magnetic force between unit 12 and do not do the injecing to first magnetism.
When the first magnetic unit 11 and the second magnetic unit 12 contact each other, the magnetic fluid of the attaching member 4 may be in an integral shape. When the first magnetic unit 11 and the second magnetic unit 12 move along the respective predetermined moving tracks, the first magnetic unit 11 and the second magnetic unit 12 are separated. As shown in fig. 2b, the bonding member 4 is separated into a first bonding unit 41 and a second bonding unit 42 by the magnetic forces of the first magnetic unit 11 and the second magnetic unit 12. When the first magnetic unit 11 and the second magnetic unit 12 continuously depart from each other, the first attaching unit 41 and the second attaching unit 42 also depart from each other, so that the first attaching unit 41 and the second attaching unit 42 can move in different areas of the surface of the first object 3, and the attaching efficiency of the first object 3 and the second object 2 is further improved. In order to maximize the attaching efficiency, as shown in fig. 2a, the first magnetic unit 11 and the second magnetic unit 12 can be changed from contacting to separating at the middle position of the second object 2, and the moving speed of the first magnetic unit 11 and the second magnetic unit 12 can be the same, so that the first magnetic unit 11 and the second magnetic unit 12 can reach the position corresponding to the two opposite ends of the second object 2 at the same time (as shown in fig. 2 c).
In one embodiment of the present application, the first magnetic attraction unit 11 may have a size equal to or larger than that of the first object 3, and the second magnetic attraction unit 12 may have a size equal to or larger than that of the first object 3 in a direction perpendicular to the parallel arrangement.
Specifically, the direction perpendicular to the above-described parallel arrangement may refer to a direction perpendicular to the cross section illustrated in fig. 2 a. When the size of the first magnetic unit 11 is greater than or equal to the size of the first object 3, and the size of the second magnetic unit 12 is also greater than or equal to the size of the first object 3, the first magnetic unit 11 can move only once along the preset moving track 111, and similarly, the second magnetic unit 12 can also move only once along the preset moving track 121, thereby further accelerating the attaching efficiency of the first object 3 and the second object 2.
In one embodiment of the present application, the attaching device may further include a control part, and the magnetic attraction part 1 includes a plurality of magnetic attraction areas 13. Here, the control member is electrically connected to the plurality of magnetically attracting regions 13, and the change in the direction of the magnetic force can be achieved by the control member changing the magnetically attracting region 13 of the attraction and adhesion member 4.
Specifically, each magnetically attractive area 13 may include an electromagnet. The control means may be configured to control which magnetic attraction area 13 of the plurality of magnetic attraction areas 13 or which magnetic attraction areas 13 attract the attaching means 4. When the magnetic attraction area 13 of the attraction attachment member 4 is changed, the direction of the magnetic force between the attachment member 4 and the magnetic attraction area 13 is also changed, so that the change of the direction of the magnetic force can be realized by changing the magnetic attraction area 13 of the attraction attachment member 4 through the control member.
Fig. 3a to 3c are schematic views illustrating a bonding process of a bonding apparatus according to another embodiment of the present application.
In one embodiment of the present application, as shown in fig. 3a to 3c, a plurality of magnetically attracted regions 13 may be arranged in parallel. Here, the magnetically attracting region 13 of the attaching member 4 may be continuously changed along the first path 131 and the second path 132, respectively, and the shape of the first path 131 and the second path 132 may be similar to the shape of the surface of the second object 2 close to the first object 3, so that the magnetically attracting region 13 may be changed along the inner surface of the second object 2, and the magnitude of the magnetic force between the attaching member 4 and the magnetically attracting region 13 may be sufficiently stabilized. When the two magnetic attraction areas 13 of the attraction bonding member 4 are changed from being in contact with each other to being separated from each other, the attachment bonding member 4 is separated into the first bonding unit 41 and the second bonding unit 42, the first bonding unit 41 moves along the change of the magnetic attraction area 13 of the first path 131, and the second bonding unit 42 moves along the change of the magnetic attraction area 13 of the second path 132. Similarly, when the first magnetic attraction unit 11 and the second magnetic attraction unit 12 are changed from being separated to being in contact with each other, the first attaching unit 41 and the second attaching unit 42 may also constitute the attaching member 4.
Specifically, in order to facilitate the attaching of the first object 3 and the second object 2, the region where the attaching is started may start from a middle position of the second object 2, as shown in fig. 3 a. It should be understood that the region where fitting starts may not be in the middle of the second object 2, and the embodiment of the present application is not limited to the position where fitting starts. In the area to be bonded, the bonding member 4 may be attracted by one magnetic attraction area 13, or may be attracted by two adjacent magnetic attraction areas 13, and the embodiment of the present application does not limit the number of the magnetic attraction areas 13. When bonding member 4 is attracted by two non-adjacent magnetically attracted regions 13, bonding member 4 is separated into first bonding unit 41 and second bonding unit 42 by two magnetic forces, as shown in fig. 3 b. When the first attaching unit 41 moves along the change of the magnetically attracting area 13 of the first path 131 and the second attaching unit 42 moves along the change of the magnetically attracting area 13 of the second path 132, the first attaching unit 41 and the second attaching unit 42 can attach the first object 3 and the second object 2 in different regions, so as to accelerate the attaching rate of the first object 3 and the second object 2 (as shown in fig. 3 c).
Fig. 4a to 4c are schematic views illustrating a laminating process of a laminating apparatus according to still another embodiment of the present application.
In one embodiment of the present application, as shown in FIGS. 4 a-4 c, the conformable device may further include an internally hollow flexible bladder 5. Flexible bladder 5 may house conformable member 4. When the attaching part 4 includes a magnetic fluid, and the magnetic force between the magnetic attracting part 1 and the attaching part 4 disappears, the magnetic fluid can be accommodated in the flexible bag 5, so as to realize the accommodation of the magnetic fluid. Flexible bladder 5 is configured to be flexible so as to avoid the influence of flexible bladder 5 on the movement of conformable member 4.
It will be appreciated that the conforming member 4 may move directly over the surface of the first object 3 when the conforming device does not include a flexible bladder 5. That is, the attaching member 4 is in direct contact with the first object 3. When the conforming means comprises a flexible bladder 5, the conforming member 4 can move indirectly over the surface of the first object 3. That is, the attachment member 4 is in indirect contact with the first object 3, and the attachment member 4 is in contact with the first object 3 via the flexible bag 5.
Having described the attaching device according to the embodiment of the present application, an attaching method according to the embodiment of the present application is described below with reference to fig. 5.
FIG. 5 is a schematic flow chart diagram of a fitting method according to one embodiment of the present application.
As shown in fig. 5, the attaching method may include the following steps. The attaching method may be performed by the attaching device described above.
In particular, fixation of the first object 3, the second object 2 and the adhesive may be involved in step 510.
In step 520, the magnetic attraction member 1 attracts the attaching member 4 by magnetic force so that the attaching member 4 applies pressure to the first object 3.
The direction of the magnetic force is changed 530 so that the conforming member 4 moves over the surface of the first object 3.
For details of each component in the attaching method, reference may be made to the above embodiments of the attaching device, and details are not described here for avoiding repetition.
