Description

Technical Field

[0001] The present invention relates to the technical field of flexible screen production, and in particular to a separation device and method for a non-straight panel structure. Background Art

[0002] With the development of flexible screen technology, many non-straight panels or display devices have appeared. During the manufacturing process of these panels, in order to adapt to the manufacture of flexible panels, the various film layers, structural layers, etc. used in their manufacturing will also be adaptively constructed into a flexible structural form.

[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 in one piece. The various membrane layers and structural layers of this structure are roughly divided into straight area and curved area, and some of the components need to be designed with a reusable access structure in the production and manufacturing process of the panel to adapt to the installation of this new structure.

[0004] For this type of panel with curved properties, the membrane layer and the structural layer are pre-stressed in the preset bending direction when leaving the factory. If the assembly process is not performed in the prescribed manner, the pre-stress or the corresponding structure will be destroyed, resulting in a decrease in the yield rate and causing 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 surface structures to address the problems of low efficiency and poor separation effect in the prior art when separating non-straight plate surface structures.

[0034] Embodiment 1

[0035] A separation device with a non-straight plate surface structure, such as Figure 1 and Figure 2 As shown, it includes a support body 1, a driving component 2 and a separation component 3.

[0036] Specifically, Figures 1 to 6 As shown, the platform body 1 includes a curved area 11 and a straight plate area 12, the straight plate area 12 is arranged on two opposite sides of the curved area 11, and the curved area 11 includes a stacked upper layer 111, a connecting layer 112 and a lower layer 113, the deformability of the upper layer 111, the connecting layer 112 and the lower layer 113 gradually decreases, and the convex portion 1121 is arranged on the top of the connecting layer 112, and the convex portion 1121 abuts against the upper layer 111. The curved area 11 is made of a deformable material, and the straight plate area 12 is made of a hard 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 convex portion 1121, the affected part of the upper layer 111 of the curved area 11 begins to gradually bulge upwards. On the contrary, when the curved area 11 gradually returns to flatness, the connecting layer 112 is reset, and the bulge gradually decreases and finally becomes flat.

[0037] Specifically, the platform body 1 is arranged on the driving component 2, and the driving component 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, respectively. The straight plate area 12 is arranged on the power arm 21, and the curved surface area 11 is arranged 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 a sufficient length so that when the power arm 21 drives the support body 1 to bend, there is enough space to accommodate the bent curved area 11. The driving component 2 is used to drive the curved area 11 to bend or flatten, and the power arm 21 drives the straight plate area 12 to bend or flatten, so that the curved area 11 is bent or flattened on the connecting shaft 23. When the support layer 4 and the main membrane layer 5 are successively adhered to the upper layer 111, the power arm 21 drives the straight plate area 12 to bend and move. During the bending process, under the convex action of the upper layer 111, an arch 51 is formed on the main membrane layer 5, and then the power arm 21 drives the straight plate area 12 to flatten. From the side, the arch 51 can accommodate the insertion of the platform part 331. If the formed arch 51 is not enough to accommodate the platform part 331, it can be bent multiple times, so as to form a sufficient bulge upward at the acted part of the upper layer 111 of the curved area 11.

[0038] The separation assembly 3 is arranged at one side of the support platform body 1. The 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 through the second rotating shaft 32. The second arm 33 is provided with a platform portion 331 at one end away from the second rotating shaft 32. The platform portion 331 is detachably connected to the main film layer 5. The separation assembly 3 is used to separate the main film layer 5 from the support platform body 1 to which the support layer 4 is attached. The second rotating shaft 32 can adjust the rotation angle. The second arm 33 has a platform portion 331 that can be inserted into the arched main film layer. The second arm 33 is driven to move by the first arm 31. The second arm 33 is rotated by the second rotating shaft 32, and the platform portion 331 is inserted from the side of 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 is gradually separated from the support platform body 1 to which the support layer 4 is attached.

[0039] Embodiment 2

[0040] The difference between this embodiment and the first embodiment is that:

[0041] Specifically, Figure 7As shown, the connection layer 112 includes a plurality of stacked connection sub-layers 1122, the convex portion includes a plurality of sub-convex portions 11221, and the tops of the plurality of connection sub-layers 1122 are each provided with at least one sub-convex portion 11221. Among the plurality of connection sub-layers 1122, the sub-convex portion 11221 of the connection sub-layer 1122 located at the top layer abuts against the upper layer 111, and the bottoms of the plurality of connection sub-layers 1122 are concave to form at least one concave portion 11222. Among the adjacent connection sub-layers 1122, one end of the connection sub-layer 1122 located at the top abuts against the straight plate area 12 The other end of the upper connecting sublayer 1122 forms a first gap 61 with another straight plate area 12, and in adjacent connecting sublayers 1122, one end of the lower connecting sublayer 1122 is connected to one straight plate area 12, and the other end of the lower connecting sublayer 1122 forms a second gap 62 with another straight plate area 12, the first gap 61 and the second gap 62 are staggered, and the concave portion 11222 of the upper connecting sublayer 1122 is engaged with the sub-convex portion 11221 of the lower connecting sublayer 1122. When the curved area is bent, the adjacent connecting sublayer 1122 located on the upper side is subjected to the bending stress and moves to the left or right while bending, and the adjacent connecting sublayer 1122 located on the lower side is subjected to the bending stress and moves to the right or left while bending. Such movement causes the sub-convex portion 11221 on each connecting sublayer 1122 to gradually separate from the concave portion 11212 and gather toward the midline position of the curved area 11. During the bending process, Under the action of the sub-protrusion 11221, the acted part of the upper layer 111 of the curved area 11 begins to gradually bulge upward. From the overall perspective of the upper layer 111, the protrusions appear from both sides of the curved area 11 as the curved area 11 gradually bends, and gradually move toward 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 connected sub-layers 1122 are restored, the protrusions gradually decrease, and finally become flat.

[0042] Specifically, 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 member 37 and a fourth arm 38. The third arm 34 is movably connected to the connecting arm 36 through the third rotating shaft 35, and the connecting arm 36 is movably connected to the fourth arm 38 through the electrically controlled rotating member 37. A clamp 381 is provided at one end of the fourth arm 38 away from the electrically controlled rotating member 37, and the clamp 381 is detachably connected to the main film layer 5. The connecting arm 36 and the fourth arm 38 are driven by the third arm 34, and the third rotating shaft 35 rotates the connecting arm 36, thereby changing the angle of the connecting arm 36, and the electrically controlled rotating member 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, and then 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 is gradually separated from the support platform body 1 of the adhesive support layer 4.

[0043] In the present invention, the support body 1 is placed on the driving component 2, and the supporting layer 4 and the main membrane layer 5 with prestress are sequentially adhered to the upper layer 111. The driving component 2 drives the curved surface area 11 to bend and move, so that the upper layer 111, the connecting layer 112 and the lower layer 113 are bent and moved respectively. During the bending process, the convex portion 1121 or the sub-convex portion 11221 is gradually lifted, and the convex portion 1121 or the sub-convex portion 11221 gradually lifts the upper layer 111, thereby forming an arched portion 51 on the main membrane layer 5, and the driving component 2 drives the curved surface area 11 to move flatly, so that the upper layer 111, the connecting layer 112 and the lower layer 113 are moved flatly respectively, and the separation component is used. The main film layer 5 is separated from the support body 1 to which the support layer 4 is adhered from the arched portion 51, and a full-shaped arched portion 51 is formed on the main film layer 5 by the curved surface area 11, so that it is convenient for the subsequent separation component 3 to peel off the main film layer 5, thereby improving the success rate and reducing the risk of shutdown alarm; the present invention uses a method that conforms to the preset bending stress of the raw material part and provides separation stress to a specific position with the same bending action, that is, the bending direction of the support body 1 is consistent with the bending direction of the bearing object (main film layer 5), so that the expected object is separated without changing the original preset stress of the raw material part, significantly ensuring the availability and yield of the raw material part after processing, which is conducive to the smooth development of subsequent processes.

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

[0045] The support body 1 is placed on the driving assembly 2, and the supporting layer 4 and the main membrane layer 5 are successively arranged on the upper layer, and the supporting layer 4 and the main membrane layer 5 are detachably connected;

[0046] The driving assembly 2 drives the two straight plate areas 12 of the platform body 1 to move closer to each other, and the curved surface area 11 is pressed to bend and move, so that the upper layer 111, the connecting layer 112 and the lower layer 113 are bent and moved respectively;

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

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

[0049] The separation assembly 3 is used to separate the main film layer 5 from the base body 1 to which the support layer 4 is adhered from the arched portion 51 .

[0050] In addition, the present invention can be adapted to the separation of film layers of flexible screens, and can significantly improve the yield and efficiency of subsequent production links. The device can also be used for the repair of finished or semi-finished flexible display devices, that is, for peeling off a specific film layer from an assembled flexible display device. The advantage of adopting the present 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 repair quality, reduction of repair losses, and improvement of repair efficiency.
