Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to an easily detachable scraper device. Background Technology

[0002] Existing doctor blade coating devices typically have two structural styles: with a drive unit or without a drive unit. Without a drive unit, the doctor blade module is usually placed directly on the coating platform for flat pushing operations. This structure results in direct friction between the doctor blade module and the coating platform, which can easily lead to scratches and gaps between the doctor blade module and the coating platform over time, thus affecting coating accuracy. When a drive unit is provided, the doctor blade module is directly welded and fixed to the crossbeam. This structural method, however, presents the problem of inconvenience in disassembling and cleaning the doctor blade after the coating operation is completed.

[0003] How to solve the above-mentioned technical problems has become an urgent technical challenge for the industry. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an easy-to-disassemble scraper device. While the scraper module is easy to disassemble, it also avoids the occurrence of friction between the scraper module and the coating platform.

The drive module is fixedly provided with a first telescopic unit. When the scraper module is set on the positioning plate, the first telescopic unit is used to fix the scraper module on the positioning plate. When the doctor blade module performs coating operations on the substrate to be coated on the coating platform located below it, the drive module drives the doctor blade module to reciprocate synchronously along the coating direction of the coating platform.

[0006] Preferably, the scraper module includes a vertical plate, and the vertical plate is provided with a positioning pin; The positioning plate is provided with positioning holes, which are matched with positioning pins; When the scraper module is mounted on the positioning plate, the positioning pin is located in the positioning hole.

[0007] Preferably, the drive module includes a drive unit disposed within the body; On the main body, the positioning plate has a through hole on the side facing away from the coating platform, and the radial extension direction of the through hole is parallel to the movement direction of the positioning plate. The first telescopic unit is fixed to the crossbar, which passes through the through hole and is connected to the drive unit.

[0008] Preferably, on the main body, a slide rail is provided on the side of the positioning plate facing away from the coating platform, and the extension direction of the slide rail is parallel to the movement direction of the positioning plate. The first telescopic unit is fixed to the crossbar, which slides along the slide rail.

[0009] Preferably, the scraper module includes a scraper and vertical plates arranged parallel to both ends of the scraper; A crossbeam is also provided between the two uprights, and a second telescopic unit is provided on the crossbeam; The second telescopic unit is connected to the scraper and is used to adjust the gap between the scraper and the substrate to be coated.

[0010] Preferably, the second telescopic unit is connected to the scraper via a magnetic attraction part.

[0011] Preferably, the scraper module further includes a baffle plate, which is disposed between the two vertical plates and is movable up and down on the forward side of the scraper.

[0012] Preferably, the scraper module further includes a third telescopic unit for connecting the upright plate and the liquid baffle plate, and the third telescopic unit is used to adjust the gap size between the liquid baffle plate and the substrate to be coated.

[0013] Preferably, the housing of the third telescopic unit is connected to the upright plate, and the telescopic rod of the third telescopic unit is connected to the baffle plate.

[0014] Preferably, the upper end of the baffle plate is inclined toward the forward side of the scraper.

[0015] The above technical solution avoids scratches and gaps caused by friction between the doctor blade module and the coating platform, thus preventing the coating accuracy from being affected; the first telescopic unit makes the disassembly of the doctor blade module more convenient; the magnetic attraction between the second telescopic unit and the doctor blade further facilitates the disassembly of the doctor blade.

The first telescopic unit 1032 is disposed on the side of the fixing plate 1033 facing the coating platform, that is, the first telescopic unit 1032 is located above the crossbeam 1043 of the scraper module 104. When the height dimension of the crossbar 1031 and the coating platform is greater than the height dimension of the crossbeam 1043 and the coating platform 102, the fixing plate 1033 may be omitted as needed, but the first telescopic unit 1032 still needs to be disposed above the crossbeam 1043.

[0042] In an exemplary embodiment, when the drive unit is disposed on the upper part of the body 101, a slide rail is provided on the side of the positioning plate 1034 facing away from the coating platform 102 on the body 101, and the extension direction of the slide rail is parallel to the movement direction of the positioning plate 1034; it can be understood that the slide rail in this design replaces the position of the through hole 105.

[0051] In one exemplary embodiment, the upper end of the baffle plate 1047 is inclined toward the forward side of the scraper 1045.

[0052] In one exemplary embodiment, as needed, during the coating operation, the coating liquid is placed on the side of the baffle plate 1047 facing the doctor blade 1045. When the doctor blade module 104 moves forward, the small gap between the baffle plate 1047 and the doctor blade 1045 restricts the free flow of the coating liquid on the surface of the substrate to be coated. Since some coating liquids evaporate very quickly, this design avoids the phenomenon of leaving traces on the edge of the surface of the substrate after the coating liquid evaporates, thus affecting the product quality.

[0053] In one exemplary embodiment, a third telescopic unit 1046 is connected to the inner side of each of the opposing upright plates 1041 as needed.
