200843870 达达号: TW3588PA IX. Description of the Invention: [Technical Field] The present invention relates to a doctor blade structure and a scraping device using the same, and in particular to a doctor blade for scraping liquid on a surface of a diaphragm Structure and application of the scraping device. [Prior Art] Liquid crystal display technology has been vigorously developed in recent years, and various sizes of liquid crystal display panels have been widely used in various consumer electronic products such as mobile phones, notebook computers, and flat-panel televisions. As consumer electronics products become more and more popular among consumers, the demand for liquid crystal display panels in the market has also increased.

Generally, a liquid crystal display panel transmits light through a liquid crystal layer and two polarizing plates to display a kneading surface. The conventional polarizing plate process includes dyeing, stretching, washing, and affixing a polyvinyl alcohol (Poly Vinyl Alcoho PVA) film. A step of triacetate cellulose film (TAC film) and drying. Since the membrane will carry a large amount of moisture on the surface after leaving the water tank, it will inevitably affect the quality of the subsequent process steps, which in turn affects the quality of the polarizing plate product. Currently, the industry generally uses a nip roll to remove moisture from the surface of the diaphragm, and two pinch rollers are used to squeeze the sides of the diaphragm to bleed water. However, this method is easy to generate water between the pinch wheels and it is impossible to remove the moisture on the surface of the diaphragm. When there is excessive moisture on the surface of the diaphragm, it will affect the quality of the TAC film and affect the drying effect of the film. TW3588PA 5 200843870

The first base 22 has a slot 221, one end of the connector 29(1) is inserted into the slot 221' and the other end of the connector 29(1) is coupled to the moving member 28(1). The moving member 28 (1) is, for example, a pneumatic cylinder that urges the first base 22 to move in the direction X to adjust the amount of force applied by the first doctor blade % contact diaphragm 80. The connector member 29(1) is of a rigid material for supporting the first blade structure 20 via the first base 22, the connector member 29) and the moving member 28(1) on the support frame 90(1). The second doctor blade structure 4 of the present embodiment preferably has the same structure as the first blade structure 20. The second doctor blade structure 4() includes a second base 42, a second to knife seat 44 and a second doctor blade 46. a second blade holder 44,

The second blade 42 is rotatably disposed above the second base 42 and the second blade 46 is disposed in the first blade holder 44. A portion of the second doctor blade % protrudes out of the second blade holder 44 and contacts the diaphragm 8G. When the button (9) moves relative to the second blade structure 40, the second blade 46 scrapes off the liquid on the surface of the diaphragm 8 . The second to blade 46 is also a resilient material f and will not be described here. The first doctor blade 26 contacts the first position ρι of the diaphragm 80, and the second to blade 46 contacts the second position P2 of the diaphragm 80. The first position P1 and the first position P 2 have a spacing - D, which is approximately Between i 5~5 5 cm. The first doctor blade 26 and the second doctor blade 46 are in close contact with the diaphragm 80, respectively, to enhance the effect of the scraping device 100 scraping liquid. Further, the second doctor blade structure 4 adjusts the angle 02' between the second doctor blade 46 and the diaphragm (10) by the rotating member 23(2). The angle 02 is approximately between about 0 degrees. The first doctor blade structure 4〇 is also connected by the connecting member 29 (the magical connecting moving member 28(2) to push the second base 42 to move.

The second raft: HV3588PA' second base 42, connector 29(2) and moving member 28(2) are supported on support frame 90(2). On the other hand, the scraping device 100 further includes at least one roller assembly. In this embodiment, the two roller assemblies 60(1) and 60(2) are taken as an example for illustration. The two roller assemblies 60 (1) and 60 (2) are respectively disposed above the first scraper structure 20 and below the second scraper structure 40 for driving the diaphragm 80 in the direction Y relative to the first scraper structure 20 and The second doctor blade structure 40 moves. When the roller assemblies 60(1) and 60(2) drive the diaphragm 80 to move, the f-film 80 is slightly tensioned so that the diaphragm 80 has a force for the first scraping blade 26 and the second scraping blade 46. It is in contact with the diaphragm 80. The above-mentioned scraper structure and the scraping device using the same according to the preferred embodiment of the present invention utilize a method in which the scraping blade is disposed in the blade holder, and a part of the scraping blade protrudes out of the blade holder and contacts the diaphragm. When the diaphragm moves relative to the doctor blade, the doctor blade scrapes off the liquid on the surface of the diaphragm, which can improve the drying effect of the diaphragm and further improve the quality of the diaphragm. In addition, the scraper structure in the scraping device is the same, and it is not necessary to design and manufacture different scraper knots, which can save cost. In this embodiment, the two scraper structures preferably maintain a spacing and are respectively in contact with the diaphragm. On the opposite sides, when the diaphragm moves relative to the first scraper structure and the second scraper structure, the first scraper blade and the second scraper blade simultaneously scrape the liquid on both surfaces of the diaphragm to improve the efficiency of scraping the liquid. In addition, since the doctor blade can adjust the angle between the diaphragm and the target force of the diaphragm +, the same scraping device can be applied to the diaphragm of different materials and thicknesses, and the material characteristics are also the same as the scraping device. Different material scraping blades can be used, which greatly improves the convenience of use.
