Description
Technical Field
[0001] The present invention relates to the technical field of flexible screen production, and in particular to a flexible display screen and a manufacturing process thereof. Background Art
[0002] Display screens are an important interface for human-computer interaction. With the continuous development of electronic information technology, people have put forward more and more diverse requirements for the functions of display screens. New applications and new requirements such as flexible display screens and transparent display screens have become an important trend in the development of industry technology. Flexible transparent LED display screens can integrate the high luminous efficiency of LED display screens, the special-shaped functional applications of flexible display screens, and the scene-based switching functions of transparent display screens, and have broad market prospects.
[0003] A Chinese patent with application number 202110454663.0 discloses a flexible transparent LED display screen, comprising: a first transparent flexible substrate, a second transparent flexible substrate and a transparent sealing layer; a circuit layer is provided on the upper surface of the first transparent flexible substrate, the circuit layer is provided with a wire area and a pad, an LED light source is provided on the pad, the LED light source and the pad are bonded together by a conductive medium, the area of the circuit layer is smaller than the area of the first transparent flexible substrate, the transparent sealing layer is provided between the upper surface of the first transparent flexible substrate and the lower surface of the second transparent flexible substrate, and the first transparent flexible substrate and the second transparent flexible substrate are bonded face to face into one. The present invention can not only realize flexible transparent display, but also ensure the reliability of LED light source bonding electrical connection, but the patent still has some shortcomings in implementation. The flexible display screen in the patent has a first transparent substrate with a surface made of flexible glass material during use. The wear resistance of the surface is poor during use. After long-term use, a large number of scratches are easily generated on the surface. At the same time, the heat dissipation effect at the bottom of the flexible screen is poor. During long-term use, due to the large amount of heat generated on the screen, the screen is prone to burn-in when the flexible screen is exposed to high temperature for a long time. At the same time, in the current production process of flexible screens, the flexible screen is mostly obtained by sequentially bonding the layers of the flexible screen. The production steps are relatively cumbersome, resulting in low production efficiency of the flexible screen. At the same time, in the production process, after the flexible screen is bonded, the two sides have a long length, and the bonding firmness between the layers on both sides after pressing is poor. During long-term bending use, the layers on both sides of the flexible screen will separate and warp, resulting in low quality of the flexible screen after production. Summary of the invention

[0022] (2) The first transparent flexible substrate and the second transparent flexible substrate are simultaneously bonded to the light source flexible circuit layer through a layer bonding mechanism, and then the wear-resistant glass layer and the flexible copper plate are simultaneously bonded to the first transparent flexible substrate and the second transparent flexible substrate, so that during the production process of the flexible screen, the upper and lower layers are evenly stressed during the bonding process of the various layers of the flexible screen, thereby achieving uniform and stable bonding of the upper and lower layers, preventing damage to the layers caused by excessive local stress, and further improving the bonding effect of the flexible screen production.

[0023] (3) After the flexible screen is laminated, the laminated flexible screen is then rolled and laminated back and forth by driving the pressure roller, which effectively prevents the edge of the laminated flexible screen from warping during subsequent use, thereby greatly improving the quality of the flexible screen after production.
[0024] (4) A flexible wear-resistant glass layer is composited on the top of the flexible screen through a layer composite mechanism, thereby improving the wear resistance of the flexible screen surface. At the same time, a flexible copper plate is composited integrally on the bottom of the flexible screen.

At this time, the third electric telescopic rod 32 drives the suction box 33 to move to clamp the composite flexible screen, so that the flexible screen is evenly stressed during the production process and the composite process between the layers of the flexible screen, so that the upper and lower layers are evenly and stably pressed together. The lamination is prevented from being damaged by excessive local force, and the quality of flexible screen production is further improved. Then, the driving mechanism drives the mounting tube 2 and the mounting plate 3 to rotate, so that they rotate to the pressing station for edge pressing, and then the first transmission electric telescopic rod 44 drives the second transmission block 45 to move, and the second transmission block 45 drives the second transmission electric telescopic rod 46 and the pressing frame 47 to move out of the mounting groove 31, and then the second transmission electric telescopic rod 46 drives the pressing frame 47 to move downward, so that the pressing roller 48 on the pressing frame 47 presses the edge of the composite flexible screen.

At the same time, a wear-resistant flexible glass layer is attached to the top of the flexible screen and a flexible copper plate 555 is attached to the bottom, which improves the heat dissipation effect and wear resistance of the flexible screen, thereby greatly improving the quality of the flexible screen;
[0056] When the pressing is completed, the driving mechanism then drives the mounting tube 2 and the mounting disk 3 to rotate to the position of the drying rack 61, and then the hot air blower 62 works. The hot air blower 62 performs hot air drying on the composite flexible screen through the pipeline and the drying box 63 to form it. After the forming is completed, the mounting disk 3 is driven to rotate to the top of the belt conveyor 9, and then the suction box 33 no longer clamps the flexible screen, so that it falls onto the belt conveyor 9 for transportation, so that the formed flexible screen is automatically unloaded, thereby realizing the automatic loading and unloading of the flexible screen and continuous automated production, which greatly improves the production efficiency of the flexible screen.

[0059] A drying rack 61 is fixedly connected to the mounting platform 1, a hot air blower 62 is fixedly connected inside the drying rack 61, an output end of the hot air blower 62 is fixedly connected to two drying boxes 63 fixedly connected to the drying rack 61 through a pipeline, and an air outlet is opened on one side of the drying box 63.
[0060] The hot blower 62 works and blows air into the drying box 63 through the pipeline, and then the drying box 63 blows air evenly through the air outlet.
[0061] The driving mechanism includes a driving motor 71 fixedly connected to the mounting table 1. The driving motor 71 is controlled by a PLC programming program, and can be controlled to rotate forward and reverse and rotate at an angle.
