Description

Technical Field

[0001] The present invention relates to the technical field of display screen processing, and in particular to a packaging device for manufacturing a flexible transparent display screen. Background Art

[0002] Flexible transparent display screen is a new display technology that combines the characteristics of transparent screen and flexible screen. Flexible transparent display screen is an upgraded and innovative design based on conventional LED transparent screen. It removes the hard light bar or PCB board, making the screen thinner and more transparent, and flexible and bendable. With the continuous advancement of science and technology and the continuous improvement of people's aesthetic needs, flexible transparent display screens will gradually replace traditional display media and become the mainstream of future display technology.

[0003] The encapsulation of flexible transparent displays is a complex and delicate process, which is crucial to ensuring the performance, reliability and service life of the displays. Good encapsulation can effectively prevent the penetration of water vapor and oxygen, and protect the electronic components inside the display from the influence of the external environment. At the same time, the encapsulation layer can also improve the flexibility and weather resistance of the display, enabling it to adapt to various complex working environments and application scenarios.

[0004] In the prior art, when a flexible transparent display is packaged, it is usually placed on a frame. The staff pours epoxy resin on the top of the display and leaves it to stand, or uses a curing lamp to cure the epoxy resin. During the curing process, the substrate cannot be fixed by other means, which may cause shaking, and there is air residue on the surface of the substrate, so bubbles may be generated, which in turn will cause defects, thereby reducing the packaging quality of the flexible transparent display.

[0022] Combine the following Figure 1 - Figure 7 The present invention is described.

[0023] like Figure 1 and Figure 2 As shown, the packaging device for manufacturing a flexible transparent display screen provided in this embodiment includes a device body 1 and a vacuum pump 2 fixedly installed on the upper end of the device body 1, a placement rack 3 is slidably arranged inside the device body 1, an adsorption plate 4 is fixedly installed on the upper end of the placement rack 3, a suction cup 5 is fixedly installed on the adsorption plate 4, an air cylinder 6 is fixedly installed on both sides of the placement rack 3, a connecting pipe 7 is fixedly installed on one side of the air cylinder 6, and one end of the connecting pipe 7 away from the air cylinder 6 is fixedly connected to the bottom end of the suction cup 5, the adsorption plate 4 is used to place the substrate, and the suction cup 5 is used to adsorb the bottom of the substrate; A reciprocating motor 8 is fixedly installed on one side of the device body 1, and a screw rod 9 is fixedly connected to the output end of the reciprocating motor 8. The screw rod 9 penetrates the device body 1 and extends to the other side of the device body 1. The screw rod 9 is rotated by the reciprocating motor 8 and is arranged above the placement frame 3. An internal thread sliding box 10 is slidably arranged on the screw rod 9. A quantitative material box 11 is fixedly installed on the device body 1. The bottom end of the quantitative material box 11 is fixedly connected to an epoxy resin conduit 12, and the end of the epoxy resin conduit 12 away from the device body 1 is fixedly connected to the upper end of the internal thread sliding box 10; Among them, the vacuum pump 2 is used to extract the air inside the device body 1, and negative pressure is generated inside the device body 1. The negative pressure transmission air cylinder 6 works and adsorbs the substrate through the suction cup 5, so that the substrate can be firmly fixed on the adsorption plate 4. At the same time, the negative pressure introduces the packaging material inside the quantitative material box 11 into the internal thread sliding box 10 through the epoxy resin conduit 12 for pouring, and then the reciprocating motor 8 is started to drive the screw 9 to rotate, and the internal thread sliding box 10 slides to evenly cover the epoxy resin on the substrate. Due to the negative pressure environment, the probability of bubble generation is greatly reduced, thereby greatly improving the packaging quality of the flexible transparent display screen.

[0024] Figure 3 This is a structural diagram of a placement frame of a packaging device for manufacturing a flexible transparent display screen provided by an embodiment of the present invention; like Figure 3 As shown, a cylinder 13 is fixedly installed on one side of the device body 1 close to the reciprocating motor 8, a telescopic rod 131 is fixedly installed on the output end of the cylinder 13, the telescopic rod 131 penetrates the device body 1 and extends to the inside of the device body 1, the placement frame 3 includes two cross frames 31 and a plurality of evenly distributed longitudinal ribs 32 fixedly installed on the upper ends of the cross frames 31, the adsorption plate 4 is fixedly installed on the upper ends of the longitudinal ribs 32, the end of the telescopic rod 131 away from the cylinder 13 is fixedly installed on the cross frame 31 by bolts, the end of the cross frame 31 away from the cylinder 13 is fixedly connected with a buffer spring 33, a transverse slide groove 101 is provided on the inner bottom side of the device body 1, and the cross frame 31 is slidably arranged inside the transverse slide groove 101 through the telescopic rod 131 and the buffer spring 33; Among them, after the epoxy resin is poured onto the substrate through the internal thread sliding box 10, the two cylinders 13 start to work. The cylinder 13 drives the cross frame 31 to slide back and forth inside the horizontal slide groove 101 through the telescopic rod 131, and then drives the adsorption plate 4 to shake through the longitudinal ribs 32, which can make the epoxy resin and the substrate fit more densely. On the one hand, it can improve the density of the epoxy resin, and on the other hand, it can make the epoxy resin coating smoother, thereby greatly reducing the defective rate of the production of flexible transparent display screens.

[0025] Figure 4 This is a structural diagram of an adsorption plate of a packaging device for manufacturing a flexible transparent display screen provided by an embodiment of the present invention; Figure 5 This is a structural diagram of an air cylinder of a packaging device for manufacturing a flexible transparent display screen provided by an embodiment of the present invention; like Figure 4 and Figure 5As shown, a return spring 61 is fixedly installed inside the air cylinder 6, and a piston 62 is fixedly connected to the upper end of the return spring 61. A rod body 63 is fixedly installed on the upper end of the piston 62. The rod body 63 penetrates the air cylinder 6 and extends to the top of the air cylinder 6. The connecting pipe 7 includes a three-way pipe 71 and a bronchial pipe 72 fixedly connected to the three-way pipe 71. The interior of the air cylinder 6 is connected to the interior of the suction cup 5 through the three-way pipe 71 and the bronchial pipe 72. When the vacuum pump 2 extracts the air inside the device body 1, the pressure inside the air cylinder 6 increases, thereby pushing the piston 62 to slide upward and extracting the air inside the connecting pipe 7. At this time, the pressure between the suction cup 5 and the bottom end of the substrate is reduced, so the substrate will be firmly fixed on the adsorption plate 4, preparing for the shaking of the placement rack 3; At the same time, if Figure 2 and Figure 7 As shown, a lifting plate 64 is fixedly installed on the upper end of the rod body 63, a metal slider 65 is fixedly installed on the side of the lifting plate 64, a vertical slide groove 102 is opened at the position of the device body 1 corresponding to the metal slider 65, and the metal slider 65 is slidably arranged inside the vertical slide groove 102; an electrode sheet 103 is fixedly arranged inside the vertical slide groove 102, and the two electrode sheets 103 are connected in series to the power circuit of the reciprocating motor 8 through a wire; In the process of the piston 62 sliding upward, the rod body 63 drives the lifting plate 64 and the metal slider 65 to slide upward. When the metal slider 65 slides inside the vertical slide groove 102 and contacts the electrode sheet 103, the reciprocating motor 8 and the cylinder 13 are energized and drive the internal thread sliding box 10 to slide through the screw rod to pour the epoxy resin. The cylinder 13 works to push the anti-sliding frame to vibrate, which simplifies the control logic. The vacuum pump 2 controls the negative pressure inside the device body 1 within a certain range and balances it with the air pressure inside the air cylinder. When the air pressure inside the device body 1 is too low, the substrate will be separated from the suction 54. At this time, the piston 62 is reset under the action of the reset spring 61, and the metal slider 65 slides down and separates from the electrode plate, thereby cutting off the power to the reciprocating motor 2 and the cylinder and stopping working.

[0026] Figure 6 This is a structural diagram of an internally threaded sliding box of a packaging device for manufacturing a flexible transparent display screen provided by an embodiment of the present invention; like Figure 6As shown, the bottom end of the internal thread sliding box 10 is fixedly connected with a distribution pipe 15, and the bottom end of the distribution pipe 15 is fixedly installed with three evenly distributed discharge nozzles 16. The bottom end of the discharge nozzle 16 corresponds to the adsorption plate 4. The inside of the distribution pipe 15 is connected with the inside of the quantitative material box 11 through the internal thread sliding box 10 and the epoxy resin conduit 12. The distribution pipe 15 plays a key role in distributing materials. Three evenly distributed discharge nozzles 16 are installed at its bottom. This design can evenly divide the material transported from the thread sliding box 10 into three paths, which flow out through three discharge nozzles 16 respectively. The three discharge nozzles 16 can ensure the uniform distribution of materials in space and improve production quality and efficiency. In addition, if Figure 1 As shown, guide rods 14 are fixedly installed on both sides of the screw rod 9, and the internal thread sliding box 10 is slidably arranged on the screw rod 9 through the guide rods 14. The guide rods 14 provide accurate movement direction guidance for the internal thread sliding box 10. When the screw rod 9 rotates, the internal thread sliding box 10 will produce an axial displacement tendency due to the thread matching with the screw rod 9, making the movement more accurate and stable. At the same time, if Figure 1 As shown, a glass door 104 is slidably provided on the outer side of the device body 1, a sealing strip 105 is fixedly provided on the upper end of the glass door 104, and a handle 106 is fixedly provided on the side of the glass door 104. The glass door 104 is slidably provided on the outer side of the device body 1, and firstly plays a protective role. The glass door 104 and the sealing strip can prevent external dust, impurities, etc. from entering the interior of the device body 1, and protect the substrate package from being disturbed by the external environment.
