Description

[0002] OLED flexible screen refers to a bendable and flexible screen. During the processing, the surface of the OLED flexible screen needs to be coated. The coating is generally directly operated by intelligent automatic equipment and can be completed without human intervention. However, before the OLED flexible screen is produced and coated on its upper surface, a protective film for scratch protection is previously attached to the surface of the OLED flexible screen. The protective film needs to be torn off. Then, in order to ensure that the OLED flexible screen is coated, dust or moisture is prevented from adhering to its surface, which affects the adhesion between the film and the OLED flexible screen, or there are black spots on the OLED flexible screen. Therefore, before the OLED flexible screen is operated, the prior art generally requires manual tearing of the protective film on the surface of the OLED flexible screen piece by piece, and then wipe the surface of the OLED flexible screen with alcohol cotton or alcohol cloth to achieve the effect of dust removal and static electricity elimination, and then put it into the intelligent automatic equipment for coating.

[0040] In the process of processing OLED flexible screens for small smart devices such as mobile phones and laptops, it is necessary to coat the surface of the OLED flexible screen. The coating is generally directly operated by intelligent automatic equipment without human intervention. However, before the OLED flexible screen is produced and coated on its upper surface, a protective film for anti-scratch protection is previously attached to the lower surface of the OLED flexible screen. The protective film needs to be torn off. Then, in order to ensure that the OLED flexible screen is coated, dust or moisture will not adhere to its surface, which will affect the adhesion between the film and the OLED flexible screen, and cause the OLED flexible When the screen is in use, there are black spots, which affect the lamination effect. Therefore, before the OLED flexible screen is coated, the prior art generally manually tears off the protective film on the lower surface of the OLED flexible screen piece by piece, and then wipes the surface of the OLED flexible screen with alcohol cotton to achieve the effect of dust removal and static electricity elimination, and then puts it into the intelligent automatic equipment for lamination. In this process, manual operation is not only inefficient, but also easy to scratch the OLED flexible screen due to operational errors. At the same time, since alcohol cotton is needed for cleaning, the loss is large and the cost is increased. At the same time, it is impossible to dry the moisture after wiping the surface of the OLED flexible screen.
[0041] Therefore, in order to improve work efficiency and realize automated assembly line processing of the entire lamination work of the OLED flexible screen, before laminating the upper surface of the OLED flexible screen, the side of the OLED flexible screen with the anti-scratch protection film is pasted as the lower surface, and the side to be coated is used as the upper surface. The worker pastes the OLED flexible screen on the left side of the electric transmission roller frame 1, and makes the lower surface contact with the transmission roller body on the electric transmission roller frame 1, and then controls the electric transmission roller frame 1 to start working, and transmits the OLED flexible screen from left to right through the electric transmission roller frame 1. When the right end face of the OLED flexible screen moves to directly below the sponge 205, the electric transmission roller frame 1 stops transmitting the OLED flexible screen, and then controls the two driving members 201 to start The mounting frame 202 starts to work, and the two driving members 201 drive the mounting frame 202 to move downward, and the mounting frame 202 drives the sponge 205, the ventilator 206 and the air inlet pipe 207 to move downward. Under normal circumstances, the protective film pasted on the lower surface of the OLED flexible screen will have a protruding portion at one of the four corners of the protective film for easy removal, so that it is easy to tear off. Therefore, when placing the OLED flexible screen, it is necessary to place the corner of the protective film on the lower surface of the OLED flexible screen with the protruding portion on the right, so that when it is transmitted to the right, it first moves to the bottom of the sponge 205, and then when the sponge 205, the ventilator 206 and the air inlet pipe 207 move downward, because the air inlet pipe 207 is connected to an external fan and other air inlet equipment, and the mounting frame 202 is located between the ventilator 206 and the sea A plurality of ventilation holes are provided between the sponges 205, and air is then introduced into the ventilation holes through the ventilator 206. Since the sponge 205 itself has a porous structure, the air can be smoothly blown toward the OLED flexible screen to remove dust from the surface of the OLED flexible screen. At the same time, the circulating air can also remove dust from the sponge 205, preventing dust from adhering to the surface or inside of the sponge 205, causing it to pollute the OLED flexible screen. At the same time, the frequent replacement of the sponge 205 is reduced, the service life is extended, and the cost is reduced. When the sponge 205 moves toward each other and contacts the protruding part of a corner of the OLED flexible screen protective film, the sponge 205 continues to move downward and squeezes the protruding part of the corner of the OLED flexible screen protective film to bend to the lower left. At the same time, In order to prevent the protruding part of one corner of the OLED flexible screen protective film from folding, resulting in a small contact area between the sponge 205 and the protruding part of one corner of the OLED flexible screen protective film, and the sponge 205 cannot be smoothly bent to the lower left, when the ventilator 206 blows air to the sponge 205, it also blows the protruding part of one corner of the OLED flexible screen protective film to bend to the lower left, thereby achieving double protection and ensuring that the protruding part of one corner of the OLED flexible screen protective film is bent to the lower left. Furthermore, when the mounting frame 202 moves downward, the inclined plate 203 and several rollers 204 are synchronously driven to move downward, and the two connecting ropes 2010 are synchronously pulled. When the lower surface of the through hole 20201 on the mounting frame 202 just moves to the same height as the lower surface of the OLED flexible screen,Several rollers 204 just come into contact with the upper surface of the OLED flexible screen. During this process, the two connecting ropes 2010 synchronously pull the slider 2012 to slide to the upper right in the slide groove set to the upper right on the two limit plates 2011, so that the pressing block 2013 moves to the upper right, so that the right side of the pressing block 2013 comes into contact with a protruding part of a corner of the OLED flexible screen protective film, and cooperates with the sponge 205 to press the protruding part of a corner of the OLED flexible screen protective film between the sponge 205 and the pressing block 2013, and in order to prevent the protruding part of a corner of the OLED flexible screen protective film from being pressed against the OLED flexible screen protective film when the OLED flexible screen continues to be transmitted to the right. When the protective film is torn off, it slides out from between the sponge 205 and the pressing block 2013. Therefore, the right side of the pressing block 2013 is set to be tooth-shaped to reduce the contact area between the pressing block 2013 and the protruding part of the corner of the OLED flexible screen protective film and increase the friction. The pressing block 2013 and the sponge 205 are set at an oblique angle. Compared with the right angle or parallel setting, it will not hinder the transmission of the OLED flexible screen to the right, and the contact area with the protruding part of the corner of the OLED flexible screen protective film is smaller. When the same force is applied to the pressing block 2013, the oblique angle setting is conducive to increasing the friction between the pressing block 2013 and the protruding part of the corner of the OLED flexible screen protective film, further improving the compacting effect.
[0042] Then the electric transmission roller frame 1 continues to transmit the OLED flexible screen to the right. When the OLED flexible screen is transmitted to the right, the protective film on its lower surface is gradually separated from its lower surface, that is, it is torn off. During the tearing process, the air blown out by the ventilator 206 synchronously removes dust from the lower surface of the OLED flexible screen. When the OLED flexible screen completely passes through the through port 20201, the two driving members 201 are controlled to bring the mounting frame 202 back to its original position, so that the slider 2012 and the pressing block 2013 automatically return to their original positions under the action of their own gravity. At the same time, after the pressing block 2013 is separated from the sponge 205 and squeezed by the two, the torn protective film is It automatically remains on the roller body on the electric transmission roller frame 1. Since the roller body is still rotating at this time, and the rotation direction is clockwise when viewed from front to back, the protective film is then transmitted to the right through the roller body. When passing between two adjacent roller bodies of the pressing block 2013, since the interval between the two roller bodies is large and the ventilator 206 is still blowing, there is a downward airflow after the airflow passes through the sponge 205. The airflow blows the right side of the protective film downward, and as the protective film is transmitted to the right, when passing between two adjacent roller bodies of the pressing block 2013, its center of gravity continues to shift to the right, and finally falls from between two adjacent roller bodies of the pressing block 2013 into the collection frame 2.
[0043] After the protective film on the lower surface of the OLED flexible screen is torn off, the electric transmission roller frame 1 continues to transmit the OLED flexible screen to the right. When the OLED flexible screen passes between the two groups of first transmission rollers 5 and the two groups of second transmission rollers 51, in the process of transmitting the OLED flexible screen to the right, the surface of the OLED flexible screen is wiped by two alcohol cloths 302 synchronously to achieve the effect of dust removal and static electricity elimination. At the same time, the transmission and cleaning are integrated and carried out simultaneously, which reduces the process and effectively improves the work efficiency. The rotation speed of the roller body on the left side of the first transmission roller 5 is greater than the rotation speed of the first transmission roller 5, and the transmission mode of the alcohol cloth 302 on the two groups of first transmission rollers 5 and the two groups of second transmission rollers 51 is wave-like transmission. Compared with the plane transmission method (that is, all rollers are located on the inner side of the alcohol cloth 302, and the alcohol cloth 302 only contacts the top four points of the rollers), not only the alcohol cloth 302 at the first transmission roller 5 will have a wiping effect on the OLED flexible screen. After the OLED flexible screen completely enters between the first transmission roller 5 and the second transmission roller 51 and continues to be transmitted to the right, the wavy alcohol cloth 302 indirectly contacts the surface of the OLED flexible screen, and each contact can produce a wiping effect. In the plane transmission method, when the OLED flexible screen is completely transmitted to the alcohol cloth 302, it cannot be wiped a second time during the transmission process, thereby effectively improving the wiping effect.
[0044] In order to ensure that the alcohol cloth 302 does not need to be replaced during long-term use, the number of shutdowns for replacement is reduced, and at the same time, the alcohol cloth 302 used for a long time is constantly kept moist to ensure its wiping effect on the OLED flexible screen, therefore, during the transmission process of the alcohol cloth 302, it needs to pass through the alcohol liquid storage frame 301, and industrial cleaning alcohol is stored in the alcohol liquid storage frame 301, thereby achieving a moisturizing effect on the alcohol cloth 302, and at the same time, the dust adhered to the surface of the alcohol cloth 302 is cleaned by the industrial cleaning alcohol in the alcohol liquid storage frame 301, so as to achieve the purpose of recycling, reduce production costs, and save resources. In addition, in order to improve the cleaning effect of dust adhered to the alcohol cloth 302, during the transmission process of the alcohol cloth 302, the alcohol cloth 302 synchronously drives the first transmission roller 303 to rotate, and then drives the first flat gear 308 through the first transmission roller 303, and drives the second flat gear 309 to rotate through the first flat gear 308, so that the second flat gear 309 simultaneously drives the cleaning roller 303 to rotate. The cleaning brush 307 rotates, and the rotation direction of the cleaning brush 307 is opposite to the transmission direction of the alcohol cloth 302. The reverse rotation setting, compared with the same direction rotation, effectively improves the deep cleaning of the dust adhering to the alcohol cloth 302, and ensures the cleanliness of the alcohol cloth 302. At the same time, the alcohol cloth 302 that has been moistened and cleaned continues to be transmitted. When passing between the first extrusion plate 305 and the second extrusion plate 306, the alcohol cloth 302 is squeezed by the first extrusion plate 305 and the second extrusion plate 306, which effectively solves the problem that the alcohol cloth 302 absorbs too much alcohol when passing through the industrial cleaning alcohol in the alcohol liquid storage frame 301, causing waste and increasing costs. In addition, the alcohol adsorption saturation of the alcohol cloth 302 is too high, and it is easy to accumulate into water droplets, which drip into the inside of the equipment, causing rust and short circuit. In addition, when wiping the OLED flexible screen, the wiping effect is not only poor, but also causes the surface humidity of the OLED flexible screen to be high. During the subsequent lamination, the viscosity between the film and the OLED flexible screen is reduced, affecting the lamination effect.
[0045] When the cleaned OLED flexible screen is transmitted between the third transmission roller 52 and the fourth transmission roller 53, since the roller rotation speed from the third transmission roller 52 to the fourth transmission roller 53 is less than the rotation speed of the second transmission roller 51, and the drying cloth 402 is also set to be wavy, when the alcohol cloth 302 wipes the OLED flexible screen, moisture is inevitably present on the surface of the OLED flexible screen, which needs to be dried. When the OLED flexible screen passes through the drying cloth 402, the moisture on the surface of the OLED flexible screen is wiped and dried by the drying cloth 402. In order to reduce the number of shutdowns and replacements of the drying cloth 402 and extend the service life of the drying cloth 402, the drying cloth 402 itself is kept dry at all times to ensure the treatment of moisture on the surface of the OLED flexible screen. Therefore, when the drying cloth 402 is transmitted, the second transmission roller 401 is synchronously driven to transmit, and the fan 403 is driven to rotate by the second transmission roller 401. Moreover, when working, the heating wire 405 is energized. The heat is transferred to the second transmission roller 401 through the electric heating wire 405, and then the second transmission roller 401 is made of a material with good heat transfer performance, so as to transfer the heat to the drying cloth 402 through the second transmission roller 401 to the greatest extent, thereby drying the drying cloth 402. At the same time, when the fan 403 rotates, it further achieves the effect of air drying, and the generated gas flow further blows the hot dried gas carrying moisture to the rear. In order to prevent the air flow carrying moisture from contacting the OLED flexible screen and causing moisture to be generated on the surface of the OLED flexible screen again, the air flow is limited by the baffle 404. During the air drying process, the fan 403 does not need to be connected to an external power device. Through the transmission of the OLED flexible screen, the transmission is realized synchronously, which effectively reduces the use of power resources, reduces costs, and is green and environmentally friendly. After the OLED flexible screen is dried, it is synchronously transmitted to the receiving plate 3, and then placed on the intelligent automatic equipment for lamination by a robot.
