Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical adhesive defoaming technology, specifically to an OCA optical adhesive defoaming device. Background Technology
[0002] OCA optical adhesive is a special adhesive used to bond transparent optical components. During the manufacturing process of OCA optical adhesive, the formation of air bubbles often occurs, which reduces the product qualification rate. Therefore, a special defoaming device is often used for processing.
[0003] In existing technologies, vacuum methods are often used to defoam OCA adhesives. The principle is to use a negative pressure environment to cause bubbles on the surface of the raw material to expand, burst, or migrate to the edge and eventually be discharged. However, before vacuum treatment, some solid dust particles remain on the surface of the OCA raw material. If they are not cleaned, they will affect the vacuum defoaming effect to a certain extent, requiring the vacuum equipment to run for a longer time to achieve defoaming, which increases the energy consumption of the equipment.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0012] Preferably, a sealing strip is movably connected to the bottom edge of the dust cover, and a sealing groove is provided on the surface of the connecting plate near the edge. The sealing strip is inserted into the sealing groove when the dust cover and the connecting plate are closed, thereby increasing the sealing performance when the two are closed and preventing external dust from entering the area protected by the dust cover from the connection point.
[0013] Preferably, both the sealing strip and the dust cover are fixedly connected to the bottom with Velcro, and the two sets of Velcro are matched in size. The Velcro structure allows the sealing strip to be quickly removed and replaced.
[0014] Preferably, the surface of the dust cover has an installation opening, and a transparent glass plate is embedded in the inner wall of the installation opening. Through the transparent glass plate, people can easily see from the outside the dust removal mechanism's dust removal and cleaning process of the OCA adhesive raw material.

[0029] In this embodiment, the surface of the connecting plate 5 is provided with mounting grooves 9 near the two side edges. A cylinder 10 is provided inside the mounting groove 9. The top of the cylinder 10 is connected to the bottom of the support plate 601. The cylinder 10 can push the dust removal mechanism 6 to rise, thereby facilitating the cleaning of OCA adhesive strips of different thicknesses and improving the adaptability of the dust removal mechanism 6 to the raw materials.
[0030] In this embodiment, a threaded hole is provided at the bottom center of the guide block 604, and a threaded post is fixedly connected at the top center of the rectangular plate 605. Through the threaded connection structure, the electrostatic dust removal brush 608 can be firmly connected to the guide block 604, making disassembly and assembly convenient and ensuring its stability after installation and docking.
[0031] In this embodiment, the protective component 7 includes a dust cover 701, which is made of plastic. A hinge is provided at the bottom edge of the dust cover 701. The dust cover 701 forms a movable structure with the connecting plate 5 through the hinge. Through the protective component 7, the dust cover 701 protects the area used by the dust removal mechanism 6, preventing external dust from falling back onto the raw materials during the dust removal operation, thus providing good protection for the dust removal step.
[0032] In this embodiment, a handle 704 is fixedly connected to the front of the top of the dust cover 701. The surface of the handle 704 has multiple sets of semi-circular grooves. By using the handle 704, people can easily open the dust cover 701 and take out the raw materials.
[0033] In this embodiment, a sealing strip 702 is movably connected to the bottom edge of the dust cover 701, and a sealing groove 8 is provided on the surface of the connecting plate 5 near the edge. The sealing strip 702 is inserted into the sealing groove 8 when the dust cover 701 and the connecting plate 5 are closed, thereby increasing the sealing performance when the two are closed and preventing external dust from entering the area protected by the dust cover 701 from the connection point between the two.

After the above steps are completed, the material is located directly below the dust removal mechanism 6. The guide block 604 moves horizontally with the threaded screw 603 driven by the first motor 602, while the electrostatic dust removal brush 608 rotates and contacts the surface of the material under the drive of the second motor 607, sweeping away solid particles attached to the surface of the substrate, so that the material is in a cleaner state for subsequent vacuum treatment, which helps to improve the effect of subsequent vacuum defoaming treatment. The cylinder 10 can push the dust removal mechanism 6 to rise, thereby facilitating the cleaning of OCA adhesive strip materials of different thicknesses and improving the adaptability of the dust removal mechanism 6 to the material.
[0037] In summary, by utilizing the above-mentioned technical solution of this utility model, the dust removal mechanism 6 can effectively remove the solid dust particles remaining on the surface of the OCA raw material before vacuum defoaming, ensuring that the raw material is in a clean state for vacuum processing and guaranteeing the processing effect of subsequent vacuum processing. In conjunction with the cylinder 10, the dust removal mechanism 6 can be pushed upwards, facilitating the cleaning of OCA strip raw materials of different thicknesses and improving the adaptability of the dust removal mechanism 6 to the raw materials. The protective component 7, with its dust cover 701, shields and protects the area where the dust removal mechanism 6 is used, preventing external dust from falling back onto the raw material during dust removal operations, thus providing excellent protection for the dust removal step. Furthermore, the good sealing between the dust cover 701 and the connecting plate 5 further enhances the protective effect.
