Description

Technical Field

[0001] The present invention relates to the field of electronic processing, and in particular to an anti-bubble touch panel coating device. Background Art

[0002] At present, in the production and processing of high-end intelligent electronic devices, when processing and coating the touch panel, it is necessary to laminate the polarizer on the glass substrate, and the two are bonded by OCA colloid. However, due to the nature of the OCA colloid itself, the temperature and humidity of the OCA colloid change during storage, causing some areas of the OCA adhesive layer to solidify prematurely. When laminating, bubbles will be generated in the corresponding areas, which will lead to bubbles in the laminating parts of the two. Secondly, during the laminating process, it is necessary to apply a liquid adhesion promoter on the OCA colloid to enhance the lamination of the two, and the adhesion promoter also penetrates into the interior of the OCA colloid to further fill the bubbles inside the OCA colloid, that is, eliminate the bubbles. However, in the prior art, it is difficult for the adhesion promoter to effectively enter the interior of the OCA colloid, and the adhesion promoter has fluidity, causing the adhesion promoter to overflow to the side of the glass substrate, causing pollution.

[0046] When the bottom glass substrate 4 is placed, the two first driving members 202 are controlled to start working, and the fixing plate 203 is driven to move to the left by the two first driving members 202, and then the limiting frame 204, the four first elastic members 205 and the placing plate 206 are driven to move to the left by the fixing plate 203, so that the bottom glass substrate 4 on the placing plate 206 moves synchronously to the left. When the bottom glass substrate 4 moves to the left, the upper surface of the bottom glass substrate 4 contacts with a plurality of cleaning soft bristles 209a provided on the cleaning roller 209, and then the dust adhering to the upper surface of the bottom glass substrate 4 is cleaned by the plurality of cleaning soft bristles 209a to prevent the dust from contaminating the upper surface of the bottom glass substrate 4 and causing a large number of bubbles and stains after the bottom glass substrate 4 is bonded to the surface polarizer 5. The dust cleaned by the plurality of cleaning soft bristles 209a is automatically pushed into the dust collecting frame 3 for collection.

[0047] As the fixed plate 203 and the dust collecting frame 3 gradually move to the left, the fixed plate 203 synchronously drives the connecting frame 301 and the wave plate 302 to move to the left. When the wave plate 302 moves to the left and contacts the first pressure rod 306, since the wave plate 302 is set to a uniformly undulating wave shape, the wave plate 302 causes the first pressure rod 306 to continuously move up and down. When the first pressure rod 306 continuously moves up and down, the first pressure rod 306 synchronously drives the first support frame 305 to compress the two second elastic members 304 while continuously sliding up and down on the two first connecting rods 303. As the first support frame 305 continuously slides up and down, the first support frame 305 synchronously drives the two first connecting plates 401 to continuously move up and down. The two first connecting plates 401 drive the two first separation plates 404 to slide up and down in the two OCA colloid storage barrels 402. When the two first separation plates 404 move downward, since the OCA colloid is stored in the lower part of the two OCA colloid storage barrels 402, the OCA colloid stored in the lower part of the two OCA colloid storage barrels 402 is pressed into the two glue delivery pipes 405 under the change of air pressure, and then pressed into the glue coating roller 406 from the two glue delivery pipes 405, and then evenly coated on the upper surface of the bottom glass substrate 4 through a plurality of first circular holes 406a provided on the lower side of the glue coating roller 406. At the same time, as the air pressure in the lower part of the two OCA colloid storage barrels 402 changes, since the height of the two glue filling pipes 407 is lower than that of the corresponding The height of the first partition plate 404 is adjacent to the two glue replenishing tubes 407, and the two glue replenishing tubes 407 are externally connected to other storage objects storing OCA colloid. Therefore, during the air pressure change process, the OCA colloid at the lower part of the two OCA colloid storage barrels 402 is replenished synchronously, thereby ensuring that the OCA colloid at the lower part of the two OCA colloid storage barrels 402 is continuously squeezed out smoothly. When the OCA colloid coated on the upper surface of the bottom glass substrate 4 moves below the plurality of puncturing devices 307, the plurality of puncturing devices 307 synchronously and continuously move up and down, thereby puncturing the bubbles retained in the OCA colloid coated on the upper surface of the bottom glass substrate 4, thereby preventing the existence of bubbles after the bottom glass substrate 4 and the surface polarizer 5 are pressed together, and making the OCA colloid coated on the upper surface of the bottom glass substrate 4 A large number of uniform small holes, as the bottom glass substrate 4 and the wave plate 302 continue to move to the left, and the wave plate 302 contacts the second pressure rod 504, and synchronously squeezes the second pressure rod 504 to move up and down, and then the second pressure rod 504 drives the second support frame 503 to compress the two third elastic members 502, while synchronously sliding up and down on the two second connecting rods 501, when the second support frame 503 moves up and down, the second support frame 503 synchronously drives the two second round rods 505 to slide up and down in the two adhesion promoter storage barrels 507, while the two second round rods 505 slide, because the lower part of the two adhesion promoter storage barrels 507 separated by the two second separation plates 506 stores the adhesion promoter, and then under the change of air pressure,The adhesion promoter stored in the lower part of the two adhesion promoter storage barrels 507 is pressed into the two infusion tubes 508, and then input into the discharge tube 5010 from the two infusion tubes 508, and then evenly added to the OCA colloid on the upper surface of the bottom glass substrate 4 from the plurality of second circular holes 5010a set on the discharge tube 5010. Since there are a large number of uniform small holes on the OCA colloid at this time, the adhesion promoter can smoothly penetrate into the OCA colloid through the small holes, and then the bubbles remaining in the OCA colloid are refilled, and the bubbles are eliminated while the OCA is filled. The colloid and the adhesion promoter are fully and evenly mixed, which is helpful for the subsequent pressing of the bottom glass substrate 4 and the surface polarizer 5. At the same time, as the air pressure changes at the bottom of the two adhesion promoter storage barrels 507, since the height of the two liquid replenishing tubes 509 is lower than the height of the adjacent second separation plate 506, and the two liquid replenishing tubes 509 are externally connected to other storage objects storing adhesion promoters, the adhesion promoters at the bottom of the two adhesion promoter storage barrels 507 are replenished synchronously during the air pressure change process, thereby ensuring that the adhesion promoters at the bottom of the two adhesion promoter storage barrels 507 are continuously and smoothly squeezed out.

[0048] When the bottom glass substrate 4 moves to the position directly below the plane polarizer 5, the two first driving members 202 stop working, and then control the two fourth driving members 705 to start working, and the two fourth driving members 705 drive the two fourth connecting blocks 706 to move downward synchronously, and then the two fourth connecting blocks 706 drive the push plate 707 and the pressing roller 708 to move downward. When the two fourth connecting blocks 706 move downward, the fourth connecting block 706 at the rear synchronously squeezes the first placing roller 603, so that the first placing roller 603 rotates around the torsion spring shaft, and then when the pressing roller 708 moves downward, The right side of the plane polarizer 5 is gradually pressed downward synchronously, so that the right side of the plane polarizer 5 is attached to the bottom glass substrate 4. At the same time, the third driving member 703 is controlled to start working, and the second connecting plate 704 is driven to move to the left by the third driving member 703, and then the two fourth driving members 705, the two fourth connecting blocks 706, the push plate 707 and the pressing roller 708 are driven to move to the left by the second connecting plate 704, so that the plane polarizer 5 is gradually pressed together with the bottom glass substrate 4 through the OCA colloid and the adhesion promoter. When pressing together, the four first elastic members 205 are used for buffering to prevent the bottom glass substrate 4 from The surface polarizer 5 is over-pressed, causing damage. At the same time, the placement plate 206 is limited by the limiting plate 207 to further prevent the bottom glass substrate 4 and the surface polarizer 5 from being over-pressed, thereby achieving a limiting effect. When the push plate 707 moves to the left to contact the third connecting block 6011, most of the surface polarizer 5 has been pressed together with the bottom glass substrate 4, and there is no need for the second placement roller 6010 and the third placement roller 6012 to press the left side of the surface polarizer 5 again. Then, the second driving member 608 is controlled to move upward, so that the second connecting block 609 and the second placement roller 6010 move upward synchronously. Move, so that the second placement roller 6010 and the third placement roller 6012 loosen the left side of the surface polarizer 5. As the pressing roller 708 continues to move to the left, the push plate 707 synchronously squeezes the third connecting block 6011 to the left, so that the third connecting block 6011 moves to the left, that is, the U-shaped frame 6014 slides to the left on the two third connecting rods 606 while compressing the two fourth elastic members 607, thereby ensuring that the pressing roller 708 can successfully press the surface polarizer 5 completely onto the bottom glass substrate 4. After the pressing is completed, the pressed bottom glass substrate 4 and the surface polarizer 5 can be manually removed.

[0049] Example 2

[0050] On the basis of Example 1, Figure 1 , Fig.16 and Fig.17As shown, a sorting system is also included. The sorting system is installed on the left side of the upper surface of the mounting base plate 1, and the sorting system includes a gantry 801, a flow limiting plate 802, a cleaning plate 803 and an equalizing plate 804; the gantry 801 is bolted to the left side of the upper surface of the mounting base plate 1; two front-to-back symmetrical flow limiting plates 802 are fixedly connected to the upper side of the gantry 801; two equalizing plates 804 are fixedly connected to the upper sides of the two gantries 801, and the two equalizing plates 804 are located between the two flow limiting plates 802; a cleaning plate 803 is fixedly connected to each of the separated sides of the two flow limiting plates 802.

[0051] The two dividing plates 804 cooperate with each other to form a V shape.

[0052] When the bottom glass substrate 4 moves to the left, and its surface is coated with OCA colloid, and an adhesion promoter is added to the OCA colloid. In order to make the OCA colloid on the surface of the bottom glass substrate 4 sufficiently flat and without excess adhesion promoter before the bottom glass substrate 4 and the surface polarizer 5 are pressed together, when the bottom glass substrate 4 passes through the two averaging plates 804, the OCA colloid on the upper surface of the bottom glass substrate 4 is flattened by the two averaging plates 804, and the excess adhesion promoter on the OCA colloid is removed simultaneously. At the same time, due to the two averaging plates The plates 804 cooperate with each other to form a V shape. Since the adhesion promoter is in liquid form, the excess adhesion promoter automatically flows to the left along the two equal-dividing plates 804 and flows to the left end of the two equal-dividing plates 804, and then flows from the two equal-dividing plates 804 to the inside of the two waste liquid collection frames 2 for collection. At the same time, the excess adhesion promoter is limited by the two flow limiting plates 802 to ensure that it does not contaminate the device. At the same time, the adhesion promoter adhering to the front and rear sides of the bottom glass substrate 4 is scraped off by the two cleaning plates 803.
