Description

Technical Field

[0001] This invention relates to the field of flexible screen manufacturing technology, and in particular to a separation device and method for a non-straight-panel structure. Background Technology

[0002] With the development of flexible screen technology, many non-flat panels or display devices have emerged. In the manufacturing process of these panels, in order to adapt to the manufacturing of flexible panels, the various film layers, structural layers and other materials used in their manufacturing are also adapted to be flexible structural forms.

[0003] The existing flexible screen structure connects two straight screens with a bendable curved screen in the middle, and the three screens can be manufactured as a whole. The various film layers and structural layers for this structure are roughly divided into straight and curved areas. Some components need to be designed with a transfer structure in the production process of this panel to adapt to the installation of this new structure.

[0004] For panels with curved properties, the film layer and structural layer are pre-stressed according to the preset bending direction at the factory. If the assembly process is not carried out in accordance with the prescribed method, the pre-stress or the corresponding structure will be damaged, resulting in a decrease in yield and economic losses. Summary of the Invention

[0005] In view of the above situation, it is necessary to provide a separation device and method for non-straight plate structures to address the problems of low efficiency and poor separation effect in the existing technology when separating non-straight plate structures.

[0006] A separation device with a non-straight-plate structure includes a support body, a drive assembly, and a separation assembly. The support body includes a curved area and a straight plate area, with the straight plate areas located on opposite sides of the curved area. The curved area includes an upper layer, a connecting layer, and a lower layer stacked together. The top of the connecting layer has a protrusion that abuts against the upper layer. A support layer and a main membrane layer are stacked from bottom to top on the upper layer. The main membrane layer is detachably connected to the support layer. The support body is mounted on the drive assembly, which drives the straight plate area to compress the curved area for bending or flattening movement. The separation assembly is located on one side of the support body and is used to separate the main membrane layer from the support body, which has the support layer.

[0007] The beneficial effects of this invention are:

[0008] The support platform is placed on the drive assembly. The support layer and the prestressed main membrane layer are then adhered to the upper layer. The drive assembly drives the curved area to bend, causing the upper, connecting, and lower layers to bend respectively. During bending, the protrusions are gradually lifted, and the protrusions at the upper end of the connecting layer gradually push up the upper layer, thus forming an arch on the main membrane layer. The drive assembly then drives the curved area to flatten, causing the upper, connecting, and lower layers to flatten respectively. The separation assembly separates the main membrane layer from the support platform with the adhered support layer from the arch. By creating a full-shaped arched portion on the main membrane layer through the curved surface area, the subsequent separation component can easily peel off the main membrane layer, improving the success rate and reducing the risk of downtime alarms. This invention uses a method that conforms to the preset bending stress of the raw material to provide separation stress at a specific location with the same bending action. That is, the bending direction of the support body and the bending direction of the supported object (main membrane layer) are consistent. Thus, the expected object is separated without changing the preset stress of the raw material, which significantly ensures the usability and yield of the raw material after processing and is conducive to the smooth progress of subsequent processes.

[0009] Furthermore, the upper layer, the connecting layer, and the lower layer are all deformable materials, and the degree of deformability of the upper layer, the connecting layer, and the lower layer gradually decreases.

[0010] Furthermore, the connecting layer includes a plurality of stacked connecting sub-layers, the protrusion includes a plurality of sub-protrusions, at least one of the sub-protrusions is provided on the top of the plurality of connecting sub-layers, the sub-protrusion of the uppermost connecting sub-layer abuts against the upper layer, and at least one recess is formed at the bottom of the plurality of connecting sub-layers.

[0011] Furthermore, in adjacent connecting sub-layers, one end of the upper connecting sub-layer is connected to one of its straight plate areas, and the other end of the upper connecting sub-layer forms a first gap with another straight plate area; one end of the lower connecting sub-layer is connected to one of its straight plate areas, and the other end of the lower connecting sub-layer forms a second gap with another straight plate area; the first gap and the second gap are staggered; and the recess of the upper connecting sub-layer is adapted to the protrusion of the lower connecting sub-layer.

[0012] Furthermore, the drive assembly includes two power arms, two first rotating shafts, and a connecting shaft. The two power arms are movably connected to the connecting shaft via the two first rotating shafts, the straight plate area is located on the power arm, and the curved surface area is located on the connecting shaft.

[0013] Furthermore, the length of the connecting shaft is greater than the length of the curved surface region.

[0014] Furthermore, the separation component includes a first arm, a second rotating shaft, and a second arm. The first arm is movably connected to the second arm via the second rotating shaft. The second arm has a platform portion at one end away from the second rotating shaft, and the platform portion is detachably connected to the main membrane layer.

[0015] Furthermore, the separation assembly includes a third arm, a third rotating shaft, a connecting arm, an electrically controlled rotating component, and a fourth arm. The third arm is movably connected to the connecting arm via the third rotating shaft, and the connecting arm is movably connected to the fourth arm via the electrically controlled rotating component. The end of the fourth arm away from the electrically controlled rotating component is provided with a clamp, and the clamp is detachably connected to the main membrane layer.

[0016] The present invention also provides a method for using a separation device with a non-straight plate structure, applied to the above-mentioned separation device with a non-straight plate structure, the method comprising the following steps:

[0017] Place the support body on the drive assembly, and then place the support layer and the main membrane layer on the upper layer. The support layer and the main membrane layer are then detached and connected.

[0018] The two straight plate areas of the support body are driven to move closer to each other by the drive component, and the curved area is squeezed to bend and move, so that the upper layer, connecting layer and lower layer of the curved area bend and move respectively.

[0019] When the curved area moves in a bending motion, the protrusion at the top of the connecting layer gradually pushes up the upper layer, forming an arch on the main film layer;

[0020] The surface area is moved horizontally by driving the component, so that the upper layer, the connecting layer and the lower layer can move horizontally respectively.

[0021] The main membrane layer is separated from the substrate body of the adhesive support layer from the arched part using a separation component. Attached Figure Description

[0034] Example 1

[0035] A separation device with a non-straight plate structure, such as Figure 1 and Figure 2 As shown, it includes a platform body 1, a drive assembly 2, and a separation assembly 3.

[0036] Specifically, such as Figures 1 to 6 As shown, the support body 1 includes a curved area 11 and a straight plate area 12. The straight plate area 12 is located on opposite sides of the curved area 11. The curved area 11 includes an upper layer 111, a connecting layer 112, and a lower layer 113 stacked together. The deformability of the upper layer 111, the connecting layer 112, and the lower layer 113 gradually decreases. A protrusion 1121 is located on the top of the connecting layer 112 and abuts against the upper layer 111. The curved area 11 is made of a deformable material, while the straight plate area 12 is made of a rigid material, such as metal or hard plastic. When the curved area 11 is bent, the connecting layer 112 is subjected to bending stress. During the bending process, under the action of the protrusion 1121, the affected part of the upper layer 111 of the curved area 11 gradually bulges upward. Conversely, when the curved area 11 gradually returns to flatness, the connecting layer 112 returns to its original position, and the protrusion gradually decreases and eventually becomes flat.

[0037] Specifically, the support body 1 is mounted on the drive assembly 2. The drive assembly 2 includes two power arms 21, two first rotating shafts 22 and a connecting shaft 23. The two power arms 21 are movably connected to the connecting shaft 23 through the two first rotating shafts 22. The straight plate area 12 is mounted on the power arm 21, and the curved surface area 11 is mounted on the connecting shaft 23. The length of the connecting shaft 23 is greater than the length of the curved surface area 11. The connecting shaft 23 has sufficient length to accommodate the curved surface area 11 after the power arm 21 drives the support body 1 to bend. The driving component 2 is used to drive the curved surface area 11 to bend or flatten. The power arm 21 drives the straight plate area 12 to bend or flatten, so that the curved surface area 11 can bend or flatten on the connecting shaft 23. When the support layer 4 and the main film layer 5 are successively adhered to the upper layer 111, the power arm 21 drives the straight plate area 12 to bend. During the bending process, under the convex action of the upper layer 111, an arch 51 is formed on the main film layer 5. Then the power arm 21 drives the straight plate area 12 to flatten. From the side, the arch 51 can accommodate the platform part 331 to be inserted. If the formed arch 51 is not enough to accommodate the platform part 331, it can be bent multiple times, so that a sufficient convexity is formed upward at the acting part of the upper layer 111 of the curved surface area 11.

[0038] Separation assembly 3 is located on one side of the support body 1. Separation assembly 3 includes a first arm 31, a second rotating shaft 32, and a second arm 33. The first arm 31 is movably connected to the second arm 33 via the second rotating shaft 32. The end of the second arm 33 away from the second rotating shaft 32 has a platform portion 331, which is detachably connected to the main film layer 5. Separation assembly 3 is used to separate the main film layer 5 from the support body 1 to which the adhesive support layer 4 is attached. The second rotating shaft 32 is adjustable in rotation angle. The second arm 33 has a platform portion 331 into which the arched main film layer can be inserted. The first arm 31 drives the second arm 33 to move, and the second rotating shaft 32 rotates the second arm 33, inserting the platform portion 331 from the side forming the arched portion 51 of the main film layer 5. Then, the first arm 31 drives the second arm 33 to move upward, so that the main film layer 5 forming the arched portion 51 gradually separates from the support body 1 to which the adhesive support layer 4 is attached.

[0039] Example 2

[0040] The difference between this embodiment and Embodiment 1 is that:

[0041] Specifically, such as Figure 7As shown, the connecting layer 112 includes multiple stacked connecting sub-layers 1122, and the protrusion includes multiple sub-protrusions 11221. Each of the multiple connecting sub-layers 1122 has at least one sub-protrusion 11221 at its top. Among the multiple connecting sub-layers 1122, the sub-protrusion 11221 of the uppermost connecting sub-layer 1122 abuts against the upper layer 111. The bottom of each of the multiple connecting sub-layers 1122 is recessed to form at least one recess 11222. In adjacent connecting sub-layers 1122, one end of the upper connecting sub-layer 1122 is connected to a straight plate area 12. The connection is such that the other end of the upper connecting sub-layer 1122 forms a first gap 61 with another straight plate 12 area. In the adjacent connecting sub-layers 1122, one end of the lower connecting sub-layer 1122 is connected to its straight plate area 12, and the other end of the lower connecting sub-layer 1122 forms a second gap 62 with another straight plate area 12. The first gap 61 and the second gap 62 are staggered. The concave portion 11222 of the upper connecting sub-layer 1122 is fitted with the convex portion 11221 of the lower connecting sub-layer 1122. When the curved area bends, the upper connecting sub-layer 1122 of the adjacent connecting sub-layer 1122 is subjected to bending stress and moves to the left or right while bending. The lower connecting sub-layer 1122 of the adjacent connecting sub-layer 1122 is subjected to bending stress and moves to the right or left while bending. This movement causes the sub-protrusions 11221 on each connecting sub-layer 1122 to gradually detach from the concave portions 11212 and converge towards the centerline of the curved area 11. During the bending process, Under the action of the sub-protrusion 11221, the affected part of the upper layer 111 of the curved area 11 begins to gradually bulge upward. From the overall view of the upper layer 111, the protrusion appears from both sides of the curved area 11 as the curved area 11 gradually bends, and gradually moves towards the center line of the curved area 11. Finally, the two protrusions merge at the center line of the curved area 11 to form a larger protrusion. Conversely, when the curved area 11 gradually returns to flatness, the multiple connecting sub-layers 1122 reset, and the protrusion gradually descends and eventually becomes flat.

[0042] Specifically, such as Figure 8As shown, the separation assembly 3 includes a third arm 34, a third rotating shaft 35, a connecting arm 36, an electrically controlled rotating component 37, and a fourth arm 38. The third arm 34 is movably connected to the connecting arm 36 via the third rotating shaft 35. The connecting arm 36 is movably connected to the fourth arm 38 via the electrically controlled rotating component 37. A clamp 381 is provided at the end of the fourth arm 38 away from the electrically controlled rotating component 37, and the clamp 381 is detachably connected to the main film layer 5. The third arm 34 drives the connecting arm 36 and the fourth arm 38, and the third rotating shaft 35 rotates the connecting arm 36, thereby changing the angle of the connecting arm 36. The electrically controlled rotating component 37 changes the angle of the fourth arm 38, so that the clamp 381 clamps the side of the arched portion 51 of the main film layer 5. Subsequently, the third arm 34 drives the connecting arm 36 and the fourth arm 38 to move upward, so that the main film layer 5 forming the arched portion 51 gradually separates from the support body 1 of the adhesive support layer 4.

[0043] In this invention, the support body 1 is placed on the driving assembly 2, and the support layer 4 and the prestressed main membrane layer 5 are sequentially adhered to the upper layer 111. The driving assembly 2 drives the curved area 11 to bend and move, so that the upper layer 111, the connecting layer 112, and the lower layer 113 bend and move respectively. During the bending process, the protrusion 1121 or the sub-protrusion 11221 is gradually lifted, and the protrusion 1121 or the sub-protrusion 11221 gradually pushes up the upper layer 111, thereby forming an arch 51 on the main membrane layer 5. The driving assembly 2 drives the curved area 11 to flatten and move, so that the upper layer 111, the connecting layer 112, and the lower layer 113 flatten and move respectively. The separation assembly is then used to complete the process. 3. The main film layer 5 is separated from the support body 1 of the adhesive support layer 4 from the arched portion 51. The arched portion 51 of the main film layer 5 is formed by the curved surface area 11, which makes it easier for the subsequent separation component 3 to peel off the main film layer 5, improves the success rate and reduces the risk of shutdown alarm. The present invention uses the same bending action to provide separation stress at a specific position in a way that conforms to the preset bending stress of the raw material. That is, the bending direction of the support body 1 and the bending direction of the supported object (main film layer 5) are consistent. In this way, the expected object is separated without changing the original preset stress of the raw material, which significantly ensures the usability and yield of the raw material after processing and is conducive to the smooth progress of subsequent processes.

[0044] The present invention also provides a method for using a separation device with a non-straight plate structure, applied to the above-mentioned separation device with a non-straight plate structure, the method comprising the following steps:

[0045] Place the support body 1 on the drive assembly 2, and then place the support layer 4 and the main membrane layer 5 on the upper layer. The support layer 4 and the main membrane layer 5 are then detached and connected.

[0046] The two straight plate areas 12 of the support body 1 are driven to move closer to each other by the drive component 2, and the curved surface area 11 is squeezed to bend and move, so that the upper layer 111, the connecting layer 112 and the lower layer 113 bend and move respectively.

[0047] During the bending process of the curved area 11, the protrusion 1121 at the top of the connecting layer 112 gradually pushes up the upper layer 111, forming an arched part 51 on the main film layer 5;

[0048] The curved surface area 11 is driven to move horizontally by the driving component 2, so that the upper layer 111, the connecting layer 112 and the lower layer 113 are moved horizontally respectively.

[0049] The main membrane layer 5 is separated from the support body 1 of the adhesive support layer 4 from the arched portion 51 using the separation component 3.

[0050] Furthermore, this invention can be adapted to the separation of film layers in flexible screens, which can significantly improve the yield and efficiency of subsequent production processes. This device can also be used for the rework of finished or semi-finished flexible display devices, that is, to peel specific film layers off the assembled flexible display devices. The advantage of using this invention is that it can significantly reduce the damage to other components of the display device during the peeling process, which greatly improves the control of rework quality, reduces rework losses, and improves rework efficiency.
