[0001] This application relates to the field of film application platform technology, and in particular to an adsorption mechanism and a film application device. Background Technology

[0002] With the development and advancement of flexible screen technology, many flexible screens now require a support film. During the film application process, the application platform adheres to the product. Currently, different sized products require application platforms of corresponding sizes, resulting in a lack of versatility and significantly impacting production efficiency and increasing costs. Summary of the Invention

[0003] In view of this, this application provides an adsorption mechanism and a film-applying device, which controls the area on the cover plate where the workpiece is adsorbed by the protrusion of the pad, thereby achieving the versatility of the adsorption mechanism.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide an adsorption mechanism, which includes a base, a cover plate, and a pad.

For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0015] like Figure 1 , Figure 2 and Figure 3In one embodiment of this application, the adsorption mechanism 100 includes a base 110, a cover plate 120, and a pad 140. The cover plate 120 is detachably connected to the base 110 and cooperates with the base 110 to form a receiving cavity 130. The receiving cavity 130 includes one or more sub-cavities 131. The cover plate 120 is provided with a plurality of vacuum holes 121 communicating with the receiving cavity 130 for adsorbing workpieces placed on the cover plate 120. At least one sub-cavity 131 is provided with a pad 140, which includes a pad layer 141 and a boss 142. The pad layer 141 is on a plane perpendicular to a first direction X and is confined in the sub-cavity 131. The first direction X is the direction from the base 110 to the cover plate 120. The boss 142 is provided on the side of the pad layer 141 away from the base 110 and is used to block the vacuum holes 121 on the cover plate 120 that are outside the target area. The target area is the area for adsorbing workpieces.

[0016] Specifically, the cover plate 120 and the base 110 are detachably connected, facilitating the removal of the pad 140 from or placement into the receiving cavity 130, thereby enabling the replacement of pads 140 of different sizes. The connection between the cover plate 120 and the base 110 can be magnetic or snap-fit, etc., without limitation. The workpiece can be, for example, a flexible screen, etc., without limitation.

[0017] The accommodating cavity 130 may contain one or more sub-cavities 131. When there is only one sub-cavity 131, a pad 140 is placed in that sub-cavity 131. When there are multiple sub-cavities 131, the sub-cavities 131 in which the pad 140 is placed can be selected. In this case, the pad 140 can be placed in one sub-cavity 131 or in multiple sub-cavities 131.

[0018] In this case, on a plane perpendicular to the first direction X, the length and width of the pad 141 are equal to the length and width of the sub-cavity 131, so that the size of the pad 141 is the same as the size of the sub-cavity 131, ensuring that the pad 140 will not shake in the sub-cavity 131 and maintaining the stability of the pad 140.

[0019] The boss 142 is disposed on the pad 141, and the side of the boss 142 close to the cover plate 120 is in contact with the cover plate 120. It can block the vacuum hole 121 on the cover plate 120. For workpieces of different sizes, the vacuum hole 121 blocked by the boss 142 will be different. This can ensure that the cover plate 120 can adsorb workpieces of various sizes. That is to say, the size of the cover plate 120 can be set to be larger than the size of the workpiece. So when it is necessary to adsorb workpieces of various sizes, the pad 140 can be used to block different vacuum holes 121, so that the area where the unblocked vacuum hole 121 is located matches the size of the workpiece. Thus, the adsorption mechanism 100 can adsorb workpieces of various sizes, improving the versatility of the adsorption mechanism 100.

[0020] In one embodiment, the adsorption mechanism 100 further includes a vacuum pump (not shown) to evacuate the accommodating cavity 130. The base 11 or cover plate 120 has a through hole through which the vacuum pump communicates with the accommodating cavity 130, thereby evacuating the accommodating cavity 130.

[0021] In one embodiment, when there are multiple sub-cavities 131, the multiple sub-cavities 131 are independently arranged and not connected to each other. At this time, there are also multiple vacuum pumps, and the multiple vacuum pumps are arranged in a one-to-one correspondence with the multiple sub-cavities 131. The vacuum pumps evacuate the corresponding sub-cavities 131, that is, the sub-cavities 131 do not share a vacuum pump. In another embodiment, when there are multiple sub-cavities 131, some sub-cavities 131 are connected and some sub-cavities 131 are not connected. The connected sub-cavities 131 can share a vacuum pump, and the non-connected sub-cavities 131 do not share a vacuum pump. In yet another embodiment, when there are multiple sub-cavities 131, all sub-cavities 131 are connected. At this time, only one vacuum pump can be used to evacuate all sub-cavities 131.

[0022] In one implementation, such as Figure 4 As shown, the first surface 122 of the boss 142 facing the cover plate 120 and the second surface 111 of the pad 141 facing the base 110 are both provided with flexible layers 150; the flexible layers 150 can help the boss 142 better block the vacuum hole 121 and enhance the sealing performance of the pad 140.

[0023] The flexible layer 150 includes at least one of silicone and rubber. Silicone or rubber has good softness and elasticity and can remain soft and unbroken in various environments. Therefore, when the workpiece is placed on the cover plate 120, the flexible layer 150 will not be damaged due to excessive weight of the workpiece. In addition, silicone or rubber can effectively fill and seal pores of various shapes.

[0024] In other embodiments, the flexible layer 150 may only be provided on the first surface 122 of the boss 142 facing the cover plate 120, or the flexible layer 150 may only be provided on the second surface 111 of the pad 141 facing the base 110. For example, in Figure 3 In this embodiment, only the first surface 122 of the boss 142 facing the cover plate 120 has a flexible layer 150. Or as... Figure 5 As shown, in other embodiments, neither the first surface 122 nor the second surface 111 is provided with a flexible layer 150.

[0025] In one embodiment, the first surface 122 of the boss 142 facing the cover plate 120 and the second surface 111 of the pad 141 facing the base 110 are provided with flexible layers 150 of the same material. Specifically, when both the first surface 122 and the second surface 111 are provided with flexible layers 150, the flexible layers 150 at these two locations are made of the same material. Therefore, during the preparation process, the same material can be used to prepare the flexible layers 150 at both locations simultaneously, which can save the time of setting the flexible layers 150 and improve the preparation efficiency.

[0026] Of course, in other embodiments, the materials of the flexible layer 150 provided on the first surface 122 of the boss 142 facing the cover plate 120 and the second surface 111 of the pad 141 facing the base 110 can also be different. For example, the material of the flexible layer 150 provided on the first surface 122 is silicone, while the material of the flexible layer 150 provided on the second surface 111 is rubber.

[0027] In one embodiment, the pad 141 and the boss 142 are made of the same material, so only one material is needed to manufacture the pad 141 and the boss 142, which can save the cost of manufacturing the pad block 140. Furthermore, using the same material can ensure the consistency of the pad 141 and the boss 142 in terms of performance and stability, eliminating the mismatch problem caused by the material difference between the pad 141 and the boss 142.

[0028] In one embodiment, the pad 141 and the boss 142 are integrally formed, which enables a tighter connection and a more stable support structure. This makes the structure of the pad 141 and the boss 142 more robust, reducing the possibility of detachment or deformation during use, effectively extending the service life of the pad 140. Furthermore, the integral forming design also improves the overall texture and aesthetics of the pad 140. Of course, in other embodiments, the pad 141 and the boss 142 can also be independent of each other and connected by means such as welding or adhesive bonding.

[0029] In one embodiment, the materials of the pad 141 and the boss 142 can both be metal, both plastic, or a mixture of metal and plastic. In other embodiments, the material of the pad 141 can be metal, and the material of the boss 142 can be plastic. In yet another embodiment, the material of the pad 141 can be plastic, and the material of the boss 142 can be metal. In summary, this application does not impose any special limitations on the materials of the pad 141 and the boss 142, but it is preferable to select materials with relatively high hardness and easy molding for the pad 141 and the boss 142. Furthermore, the materials of the pad 141 and the boss 142 can be the same or different.

[0030] Continue reading Figure 1 and Figure 2 In one embodiment of this application, the pad 141 is provided with a hollow area 20. The orthographic projection of the boss 142 on the plane of the pad 141 and the orthographic projection of the hollow area 20 on the plane of the pad 141 are spaced apart, that is, the hollow area 20 is located outside the boss 142. Specifically, the hollow area 20 of the pad 141 can increase the space in the sub-cavity 131 where the pad 140 is located, ensuring sufficient vacuum during vacuuming, so that the workpiece is more firmly adsorbed on the cover plate 120. Moreover, the hollow area 20 also makes it easier for the operator to insert disassembly and assembly tools into the sub-cavity 131 to put the pad 140 into or take out of the cavity.

[0031] In one embodiment, see further. Figure 1 The adsorption mechanism 100 further includes a separator 160 disposed in the accommodating cavity 130 to divide the accommodating cavity 130 into a plurality of sub-cavities 131.

[0032] Specifically, the material of the isolation member 160 can be metal or plastic. The isolation member 160 can provide support for the cover plate 120. When the workpiece is placed on the cover plate 120, the isolation member 160 can share part of the weight of the workpiece to ensure the support strength of the adsorption mechanism 100.

[0033] It should be noted that in other embodiments, the spacer 160 may not be provided in the receiving cavity 130. In this case, such as Figure 5 As shown, the accommodating cavity 130 includes only one sub-cavity 131, and a pad 140 is provided in the sub-cavity 131. At this time, the vacuum pump can evacuate the area above the pad 140 where no boss 142 is provided, and the vacuum pump can also evacuate the accommodating cavity 130 through the through hole provided on the side wall of the base 110.

[0034] In one embodiment, combined with Figure 1 and Figure 2When there are multiple sub-cavities 131, the sub-cavity 131 where the pad 140 is located is defined as the first sub-cavity 1311, and the sub-cavities 131 adjacent to the first sub-cavity 1311 are defined as the second sub-cavities 1312 (here, the first sub-cavity 1311 and the second sub-cavity 1312 are...). Figure 2 The two sub-cavities 131 on the right side are defined as follows: the isolation member 160 between the first sub-cavity 1311 and the second sub-cavity 1312 is defined as the first isolation member 161. The first isolation member 161 is provided with a through hole 170, wherein the hollow area 20 provided on the pad 141 is connected to the through hole 170 so that the first sub-cavity 1311 and the second sub-cavity 1312 are connected.

[0035] Specifically, the hollow area 20 on the pad 141 is connected to the through hole 170, so that the first sub-cavity 1311 and the second sub-cavity 1312 are connected. In this way, the first sub-cavity 1311 and the second sub-cavity 1312 can share a vacuum pump, reducing equipment costs.

[0036] Continue reading Figure 1 and Figure 2 When the first sub-cavity 1311 and the second sub-cavity 1312 are not connected (here, the first sub-cavity 1311 and the second sub-cavity 1312 are...) Figure 2 The two sub-cavities 1311 on the left side of the pad 141 are separated by a predetermined distance from the perforated area 20 on the pad 141. Specifically, the first sub-cavity 1311 and the second sub-cavity 1312 are not connected. Each of the first sub-cavity 1311 and the second sub-cavity 1312 corresponds to a vacuum pump, so the vacuum levels of the first sub-cavity 1311 and the second sub-cavity 1312 can be different to meet various adsorption requirements. Since the first sub-cavity 1311 and the second sub-cavity 1312 do not need to be connected, the perforated area 20 does not need to be connected to the second sub-cavity 1312. At this time, the vacuum pump corresponding to the first sub-cavity 1311 can evacuate the first sub-cavity 1311 from below the perforated area 20.

[0037] In one implementation, such as Figure 1 and Figure 2 As shown, the first sub-cavity 1311 where the pad 140 is located is the outermost sub-cavity 131 among the multiple sub-cavities 131. Specifically, placing the pad 140 in the outermost sub-cavity 131 makes it easier to accommodate workpieces of different sizes. Of course, in other embodiments, the pad 140 can also be placed in a sub-cavity 131 in the middle position.

[0038] In one implementation, such as Figure 2As shown, in the second direction Y, a pad 140 is provided in the outermost sub-cavity 131 of the multiple sub-cavities 131. The second direction Y is the length direction of the cover plate 120, so that the vacuum hole 121 of the outermost sub-cavity 131 can be better adjusted to clear or block, thereby adapting to workpieces of different sizes.

[0039] As can be seen from the above, this application utilizes the pad 140 to block the vacuum hole 121, so that the area where the unblocked vacuum hole 121 is located matches the size of the workpiece, thereby allowing the adsorption mechanism 100 to adsorb workpieces of various sizes. On the other hand, a hollow area 20 is set on the pad 141, which can not only ensure the vacuum level of the sub-cavity 131, but also facilitate disassembly. Therefore, the solution of this application has a simple structure, can improve the accuracy of workpiece positioning, and is also easy to disassemble and assemble.

[0040] This application also includes a second technical solution: a film-applying device, including the adsorption mechanism 100 of any of the above-mentioned methods. Using the adsorption mechanism 100, the film-applying device can block the vacuum hole 121 on the cover plate 120 outside the target area by using the protrusion 142 in the pad 140 to adjust the adsorption position on the cover plate 120, thereby enabling film application on workpieces of various sizes.

[0041] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
