Description

Technical Field

[0001] The utility model relates to a dust sticking device, in particular to an online dust sticking device suitable for a laminating part of an OLED optical film coating machine. Background Art

[0002] Flexible OLED optical film coating machine, also known as high-precision optical film coating machine, is used for optical film glue coating and compounding process. The coating process refers to applying a layer of glue, pigment or ink with specific functions on the surface of the substrate and then drying it. The compounding process is the process of pasting the coated substrate with another substrate. Flexible OLED optical film is generally compounded by PET film and release film.

[0003] Although the existing optical film production workshop is a dust-free workshop, some small particles of impurities and short fibers will still stick to the composite roller during operation of the equipment. The existing flexible OLED optical film coating machine does not have an online dust-binding device at the composite part. During the bonding process, the impurities on the composite roller will be brought to the surface of the optical film product and even damage the bonded film material, reducing the product production yield. Summary of the invention

[0004] The utility model provides an online dust-binding device suitable for the laminating part of an OLED optical film coating machine, and solves the problem in the prior art that the OLED optical film coating machine has no online dust-binding device at the laminating part, which affects the product production yield.

[0005] The above technical problems of the utility model are mainly solved by the following technical solutions: an online dust-binding device suitable for the laminating part of an OLED optical film coating machine, comprising two parallel mounting side plates, a laminating steel roller horizontally rotatably connected between the two mounting side plates, and a laminating rubber roller horizontally rotatably connected between the two mounting side plates, wherein the laminating steel roller and the laminating rubber roller are mutually circumscribed and laminated, and characterized in that two sets of dust-binding components are further arranged between the two mounting side plates, and the dust-binding components include two first sliding seats that slide relative to the mounting side plates, and a first sliding seat horizontally connected to the two first sliding seats. A first shaft between the movable seats, a dust-sticking rubber roller rotatably mounted on the first shaft, two second sliding seats slidably matched with the mounting side plates, a second shaft horizontally connected between the two second sliding seats, a release paper winding roller rotatably mounted on the second shaft, and four cylinders that push the sliding seats to slide back and forth; under the action of the cylinders, the first sliding seats on the two sets of dust-sticking components can respectively drive the two dust-sticking rubber rollers to achieve external bonding with the bonding steel roller and the bonding rubber roller, and the second sliding seats on the two sets of dust-sticking components can respectively drive the two release paper winding rollers to achieve external bonding with the two dust-sticking rubber rollers.

[0006] The utility model is integrated into the bonding part of the existing OLED optical film coating machine, that is, the compound process part. After coating and drying, the PET film and the release film are introduced from different directions into the area where the bonding steel roller and the bonding rubber roller abut each other, and are compounded with each other under pressure; at the same time, the two sets of dust sticking components can perform real-time dust sticking operations on the bonding steel roller and the bonding rubber roller. The specific dust sticking principle is: the first sliding seat and the second sliding seat are driven by the cylinder to move back and forth to realize the position switching of the dust sticking rubber roller and the release paper winding roller. When the release paper winding roller is pressed on the dust sticking rubber roller, and the dust sticking rubber roller is pressed on the bonding steel roller or the bonding rubber roller, the dust sticking component is in a dust sticking state; when the release paper winding roller is separated from the dust sticking rubber roller, and the dust sticking rubber roller is separated from the bonding steel roller or the bonding rubber roller, the dust sticking component is in an idle state. The release paper winding roller is wrapped with release paper tape. After tearing off the release paper on the outside, the release paper winding roller has a dust-sticking effect. The dust-sticking rubber roller can stick away impurities on the surface of the laminating steel roller or laminating rubber roller, while the release paper winding roller can stick away impurities and dust on the dust-sticking rubber roller. As the impurities and dust on the surface increase, the adhesion effect of the release paper winding roller will gradually weaken, so it is necessary to tear off the part of the tape that is about to expire every once in a while to expose a new tape.

[0007] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The utility model is adapted to the bonding part of the existing OLED optical film coating machine. Without affecting the laminating process of the coating machine, the bonding steel roller and the bonding rubber roller thereon can be subjected to real-time dust removal operations, which can significantly reduce the defects of the product such as contamination by impurities, top damage, scratches, etc., and improve the yield rate of the product.

[0013] Example 1: See Figure 1 and Figure 2 , an online dust-sticking device suitable for the laminating part of an OLED optical film coating machine, comprising two parallel mounting side plates 100, a laminating steel roller 200 horizontally rotatably connected between the two mounting side plates, and a laminating rubber roller 300 horizontally rotatably connected between the two mounting side plates, the laminating rubber roller is located directly below the laminating steel roller and is circumferentially laminated with the laminating steel roller, and two sets of dust-sticking components 400 are also arranged between the two mounting side plates, one set is located directly above the laminating steel roller, and the other set is located directly below the laminating rubber roller, the dust-sticking components include two first sliding seats 410 slidably matched with the mounting side plates, a first shaft rod 420 horizontally connected between the two first sliding seats, a dust-sticking rubber roller 430 rotatably sleeved on the first shaft rod, two second sliding seats slidably matched with the mounting side plates, a second shaft rod 450 horizontally connected between the two second sliding seats, a release paper winding roller 460 rotatably sleeved on the second shaft rod, and four cylinders 470 that push the sliding seat to slide back and forth (see Figure 3 ), the flexible colloid on the sticky rubber roller is MBR rubber; under the action of the cylinder, the first sliding seats on the two sets of sticky components can respectively drive the two sticky rubber rollers to achieve external bonding with the laminating steel roller and the laminating rubber roller, and the second sliding seats on the two sets of sticky components can respectively drive the two release paper winding rollers to achieve external bonding with the two sticky rubber rollers.

[0014] See Figure 3 The dust-binding assembly also includes two parallel and vertically distributed slide rails 480. The first slide seat and the second slide seat on the same side are fixed on the slide rails. There are also two guide seats 490 slidably matched on the slide rails, and the guide seats are fixedly connected to the mounting side plates.

[0015] See Figure 3The first sliding seat and the second sliding seat are both provided with a fixed block 10 and a clamping block 20 fixed relative thereto. The clamping block is detachably connected and fixed to the fixed block by bolts. A clamping cavity 30 for clamping and fixing the first shaft rod or the second shaft rod is defined between the fixed block and the clamping block. The clamping block can be separated from the fixed block by loosening the bolts, so that the first shaft rod or the second shaft rod can be removed easily. In particular, the release paper winding roller needs to be regularly replaced with new release paper.

[0016] This embodiment is integrated into the bonding part of the existing OLED optical film coating machine, that is, the compound process part. After coating and drying, the PET film and the release film are introduced from different directions into the area where the bonding steel roller and the bonding rubber roller abut each other, and are compounded with each other under pressure; at the same time, the two sets of dust sticking components can perform real-time dust sticking operations on the bonding steel roller and the bonding rubber roller. The specific dust sticking principle is: the first sliding seat and the second sliding seat are driven by the cylinder to move back and forth to realize the position switching of the dust sticking rubber roller and the release paper winding roller. When the release paper winding roller is pressed on the dust sticking rubber roller, and the dust sticking rubber roller is pressed on the bonding steel roller or the bonding rubber roller, the dust sticking component is in the dust sticking state; when the release paper winding roller is separated from the dust sticking rubber roller, and the dust sticking rubber roller is separated from the bonding steel roller or the bonding rubber roller, the dust sticking component is in an idle state. The release paper winding roller is wrapped with release paper tape. After tearing off the release paper on the outside, the release paper winding roller has a dust-sticking effect. The dust-sticking rubber roller can stick away impurities on the surface of the laminating steel roller or laminating rubber roller, while the release paper winding roller can stick away impurities and dust on the dust-sticking rubber roller. As the impurities and dust on the surface increase, the adhesion effect of the release paper winding roller will gradually weaken, so it is necessary to tear off the part of the tape that is about to expire every other time to expose the new tape. In normal use, the new tape can be used to continuously produce products of about 2,000 meters in length.

[0017] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
