Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a fixture for preventing overflow of coating on curved screens. Background Technology

[0002] Curved screens, such as 3D structured glass, undergo Physical Vapor Deposition (PVD) coating. During the coating process, there are areas on the curved screen that require coating and areas that do not. In existing technologies, a common method to prevent PVD overflow is to apply a protective film to the areas that do not require coating. However, this method is costly because the protective film cannot be reused; furthermore, the precision required during film application is difficult to control, resulting in the film layer extending beyond the areas that do not require coating or failing to completely cover the areas that do not require coating, thus failing to effectively prevent overflow. Utility Model Content

[0003] In view of this, the purpose of this utility model embodiment is to provide a fixture for preventing overflow of curved screens, which can reduce costs and improve the overflow prevention effect.

[0004] To address one of the aforementioned problems, the present invention provides a fixture for preventing spillage of curved screens, the fixture comprising a shielding component and a base plate;

[0005] The shielding component includes a first shielding member and a second shielding member. The first shielding member is provided with a first shielding portion that fits into a first area to be shielded of the curved screen, and the second shielding member is provided with a second shielding portion that fits into a second area to be shielded of the curved screen.

[0006] The first and second shielding components are detachably fixed to both ends of the base plate, in accordance with the length of the curved screen.

[0007] Optionally, the first shielding portion and / or the second shielding portion includes at least one layer of high-temperature adhesive with a heat resistance temperature of 100°C-160°C.

[0008] Optionally, the outer layer of the high-temperature adhesive is provided with at least one alloy shell.

[0009] Optionally, the shielding component further includes a straight connecting part, which is adapted to the length of the curved screen to connect the first shielding member and the second shielding member, so that the shielding component can shield the first area to be shielded and the second area to be shielded.

[0010] Optionally, the end of the straight connecting part connected to the first blocking member and / or the other end connected to the first blocking member is provided with a telescopic connecting part, and the telescopic connecting part connects the first blocking member and / or the second blocking member.

[0011] Optionally, the first and second shielding members are provided with a first through hole, and the base plate is provided with a second through hole; the first and second shielding members are fixed to the base plate through the first and second through holes.

[0012] This invention offers the following advantages: Targeting the 3D characteristics of curved screens, this invention provides shielding components for the 3D portions (areas to be shielded) of the curved screen that do not require coating. Based on the length of the curved screen, the shielding components are fixed to the base plate. For the same type of curved screen, the shielding components fixed to the base plate can be reused. For shielding components with different lengths, only the installation position needs to be adjusted for reuse, saving costs. Furthermore, the shape of the shielding component conforms to the shape of the area to be shielded, effectively shielding and improving the anti-overflow effect. Attached Figure Description

[0022] Please see Figure 1-5 , Figure 1 This is a schematic diagram of a fixture for preventing spillage from a curved screen; Figure 2 This is a structural schematic diagram of a shielding component; Figure 3 This is a structural diagram of an area to be covered. In the diagram, the blue dotted line represents the straight connecting part at the bottom of the product, which is not visible, and the yellow area represents the area to be covered. Figure 4 This is a structural diagram of a straight-line connector; Figure 5 This is a structural schematic diagram of a telescopic connection. In this embodiment, the present invention provides a fixture for preventing spillage of a curved screen, the fixture including a shielding component and a base plate;

[0023] The shielding component includes a first shielding member and a second shielding member. The first shielding member is provided with a first shielding part that fits into a first area to be shielded on the curved screen, and the second shielding member is provided with a second shielding part that fits into a second area to be shielded on the curved screen.

[0024] The first and second shielding components, along with the curved screen, can be detachably fixed to both ends of the base plate according to their respective lengths.

[0025] Specifically, several shielding components can be set on the base plate, with "several" representing more than one.

[0026] The first and second blocking elements can be the same or different, depending on the area to be blocked on the curved screen. Their number and position are not limited, and the number of areas to be blocked on the curved screen can be the same. The shapes of the first and second blocking areas can be the same or different.

[0027] The first and / or second shielding portions include at least one layer of high-temperature adhesive with a heat resistance temperature of 100°C-160°C, such as 120°C, 130°C, or 140°C. The outer layer of the high-temperature adhesive is provided with at least one alloy shell, such as an aluminum alloy shell, which can support the high-temperature adhesive and increase the number of times the shielding portion can be reused.

[0028] The dimensions of the base plate can be set according to the number and distance of the shielding components, and the dimensions of the shielding components can be set according to the dimensions of the curved screen. For example, the base plate length is 546mm and the base plate width is 168mm; the shielding component width is 73.41mm and the total length of the shielding assembly is 159.93mm; the curved screen length is 160.83mm and the width is 74.97mm.

[0029] The first and second blocking parts may include curved cavities that fit the area to be blocked, for conforming to the area to be blocked.
