Description

Technical Field

[0001] This utility model generally relates to the field of ultra-thin glass, and more particularly to a support fixture for screen printing on ultra-thin glass. Background Technology

[0002] With the continuous upgrading and functional expansion of electronic products, the materials and requirements for electronic product cover plates are also constantly being updated and strengthened. As a cover plate for electronic products, it needs to possess a certain degree of hardness and strength to protect the screen and internal structure, while also having good transparency to accurately and richly display the clarity and aesthetics of the screen's image. Glass, with its superior transmittance and other advantages, is more conducive to presenting the clarity and aesthetics of the image without damage. Especially with the increasing demand for thinner and more portable electronic products, cover plates are required to be as thin as possible and have foldable capabilities. The emergence of foldable screens has attracted widespread attention from all sectors of society. Currently, some flexible screen cover plates use plastic materials, while others use glass.

[0003] Ultra-thin glass (UTG) refers to flexible glass with a thickness of less than 100μm. After surface processing and edge treatment, UTG possesses advantages such as high bending performance and is widely used in various electronic industries, marking a significant milestone for the foldable display industry and becoming an important player in the foldable and flexible field after CPI cover glass. When used as a component in electronic products, UTG requires the addition of different functions depending on the product's needs, such as printing different coatings on the UTG. Therefore, a platform capable of supporting the UTG is needed to allow for the printing of the required coatings onto its surface. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a carrier fixture for ultra-thin glass screen printing.

[0005] In a first aspect, a carrier fixture for ultra-thin glass screen printing is provided, comprising:

[0006] The support plate includes at least a first surface, which is planar, and has an ultra-thin glass adsorption area.

[0007] A contour plate is replaceably attached to the first surface, and the contour plate is provided with contour through holes for placing ultra-thin glass. The orthogonal projection of the contour through holes on the support plate is located within the ultra-thin glass adsorption area.

[0008] As an option, the thickness of the contour plate is no greater than the thickness of the ultrathin glass.

[0009] As an implementation method, the first surface of the support plate is divided into an ultra-thin glass placement area and other areas, the other areas being arranged around the ultra-thin glass placement area, and the range of the ultra-thin glass placement area being less than or equal to the range of the ultra-thin glass adsorption area.

[0010] As an alternative, the support plate is a vacuum adsorption plate, and the ultra-thin glass adsorption area on the support plate has multiple vacuum adsorption holes for adsorbing the ultra-thin glass placed in the ultra-thin glass placement area.

[0011] As a possible approach, the cross-section of the contoured through-hole is matched to the dimensions of the ultrathin glass.

[0012] As an example, the thickness of the contour plate is 0.01-2 mm.

[0013] As an option, the profile plate is a steel plate.

[0014] According to the technical solution provided in the embodiments of this application, by setting separate contour plates and support plates, the surface of the support plate that contacts the ultra-thin glass is set as a plane, and an area for adsorbing the ultra-thin glass is set on the support plate, making the preparation and provision of the support plate simpler. The contour plate can be customized and selected according to different sizes of ultra-thin glass. After the contour plate and support plate are attached, it can meet the requirements of screen printing on ultra-thin glass. At the same time, the contour plate can be replaced according to different sizes of ultra-thin glass. Compared with directly processing the groove on the support plate to accommodate the ultra-thin glass, the separate structure of the contour plate is more convenient and faster, easier to process, and lower in cost. At the same time, the same support plate is used for ultra-thin glass of different sizes, and the contour plate can be replaced during the processing, which can adapt to glass of various sizes, making the processing more convenient and the processing cost lower.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Please refer to Figures 1 to 3 , Figure 5 As shown, this embodiment provides a carrier fixture for ultra-thin glass screen printing, comprising:

[0027] The support plate 10 includes at least a first surface, which is planar, and has an ultra-thin glass adsorption area.

[0028] The contour plate 20 is replaceable and can be attached to the first surface. The contour plate 20 is provided with contour through holes 21 for placing ultra-thin glass. The orthogonal projection of the contour through holes 21 on the support plate 10 is located within the ultra-thin glass adsorption area.

[0029] The support fixture provided in this embodiment has a separate profile plate 20 and a support plate 10. The surface of the support plate 10 that contacts the ultra-thin glass is flat. An area for adsorbing the ultra-thin glass is provided on the support plate 10, which simplifies the preparation and provision of the support plate 10. The profile plate 20 can be customized and selected according to different sizes of ultra-thin glass. The profile plate 20 and the support plate 10 can be used together to meet the requirements of screen printing on ultra-thin glass. At the same time, the profile plate 20 can be replaced according to different sizes of ultra-thin glass. Compared with directly processing the groove for accommodating ultra-thin glass on the support plate 10, the separate structure of the profile plate 20 is more convenient and faster, easier to process, and lower in cost. In addition, the same support plate 10 is used for ultra-thin glass of different sizes. The profile plate 20 can be replaced during processing, which can adapt to glass of various sizes, making processing more convenient and lower in cost.

[0030] like Figure 1 and Figure 2 As shown, a support plate 10 is provided, one side of which is used to attach a contour plate 20. The contour plate 20 can be fixed to the support plate 10 in various ways, such as by gluing, vacuum adsorption, etc. Figure 5 The template 20 shown is provided with a contoured through-hole 21, which is used to match the ultra-thin glass to be printed. The size of the template 20 itself is not limited; it can be set to the same size as the support plate 10, or it can be... Figure 1 As shown, this is a separate size setting, which saves costs; as Figure 3 and Figure 4 The support plate 10 shown is provided with through holes for vacuum adsorption as required.

[0031] Optionally, the thickness of the template 20 is not greater than the thickness of the ultra-thin glass. In this embodiment, the template 20 and the support plate 10 are prepared separately and then used together, which reduces processing costs and improves processing convenience. At the same time, it is also necessary to meet the requirements of ease of printing on the support plate 10 and ensuring that the printing quality meets the requirements. In order to facilitate the smooth scraping of the screen and other jigs used for printing across the surface of the ultra-thin glass, it is preferable to set the thickness of the template 20 to be less than or equal to the thickness of the ultra-thin glass, so that the ultra-thin glass is slightly higher than the template 20, which facilitates the smooth movement of the screen from one side of the ultra-thin glass to the other side to achieve printing on the ultra-thin glass.

[0032] Optionally, the first surface of the support plate 10 is divided into an ultra-thin glass placement area and other areas, the other areas being arranged around the ultra-thin glass placement area, and the range of the ultra-thin glass placement area being less than or equal to the range of the ultra-thin glass adsorption area.

[0033] In this embodiment, the contour plate 20 placed on the support plate 10, and the ultra-thin glass matching the contour plate 20, both need to be fixedly adsorbed onto the support plate 10 to facilitate steps such as positioning of the contour plate 20 and the ultra-thin glass, and screen printing of the ultra-thin glass. The surface of the support plate 10 is divided into regions to form, as shown in the figure. Figure 4 The layout shown includes an ultra-thin glass placement area A on the support plate 10, which is located in the middle of the support plate 10. Surrounding the ultra-thin glass placement area A are other areas B. Area A is used to place and fix the ultra-thin glass, and its range varies depending on the size and shape of the ultra-thin glass and is not unique.

[0034] In this embodiment, the fixation between the contour plate 20 and the support plate 10 can be achieved by adhesive bonding or vacuum adsorption. Vacuum adsorption is preferred for fixing the ultra-thin glass to the support plate 10, facilitating the handling and printing of the ultra-thin glass. Preferably, vacuum adsorption is used to adsorb the contour plate 20 and the ultra-thin glass. The ultra-thin glass is adsorbed and fixed by setting an ultra-thin glass adsorption area C on the support plate 10. This ultra-thin glass adsorption area C is generally large enough to meet the fixing requirements of ultra-thin glass of different sizes. Therefore, the range of the ultra-thin glass adsorption area C is larger than the range of the ultra-thin glass placement area A. Simultaneously, the contour plate 20 located on the support plate 10 also needs to be fixed, preferably also by adsorption. The contour plate 20 will occupy part of the ultra-thin glass adsorption area C, and the contour through-hole 21 on the contour plate 20 matches and overlaps with the ultra-thin glass placement area A, in order to achieve the adsorption and fixing of ultra-thin glass of different sizes and shapes.

[0035] Furthermore, the support plate 10 is a vacuum adsorption plate, and the ultra-thin glass adsorption area on the support plate 10 is provided with a plurality of vacuum adsorption holes 21 for adsorbing the ultra-thin glass placed in the ultra-thin glass placement area.

[0036] In this embodiment, vacuum adsorption is preferably used to fix the ultra-thin glass and / or the contour plate 20. The support plate 10 is set as a vacuum adsorption plate, and the support plate 10 is provided with regularly distributed vacuum adsorption holes 21, generally in an array. This ensures that when the ultra-thin glass is placed in the ultra-thin glass adsorption area C, the adsorbed ultra-thin glass is subjected to uniform force, making it less prone to breakage due to localized stress, and ensuring that the ultra-thin glass itself will not be damaged due to operation or other issues. In this embodiment, a vacuum channel is set on the side of the support plate 10 away from the contour plate 20 to ensure that the side where the contour plate 20 is placed has good flatness. When handling the ultra-thin glass, the glass surface is less likely to be scratched or other problems, ensuring that no other abnormalities are added to the glass in the current printing step. Preferably, the vacuum adsorption holes 21 on the support plate 10 can be configured as multi-channels, such as two channels. One channel connects to the vacuum adsorption hole 21 for adsorbing and fixing the ultra-thin glass, and the other channel connects to the vacuum adsorption hole 21 for adsorbing and fixing the contour plate 20. In use, the contour plate 20 is first placed on the support plate 10, and a vacuum is drawn through one channel to adsorb and fix the contour plate 20 to the support plate 10. Then, the ultra-thin glass is placed in the contour through hole 21 on the contour plate 20 for positioning. After positioning, a vacuum is drawn through the other channel to adsorb and fix the ultra-thin glass, so as to facilitate the subsequent screen printing steps.

[0037] Since the support fixture in this embodiment can be applied to ultra-thin glass of different shapes and sizes, when the size of the ultra-thin glass is changed, the corresponding vacuum adsorption hole 21 will also change. Specifically, the vacuum adsorption hole 21 can be divided into more control pipelines according to actual needs, so as to more accurately control the ultra-thin glass placement area and meet the printing needs of more types of glass.

[0038] Optionally, the cross-section of the contoured through-hole 21 matches the dimensions of the ultrathin glass. For example... Figure 1 and Figure 2 As shown, the through hole 21 on the template 20 is used to place the ultra-thin glass to be printed. The shape of the through hole 21 is set to be the same as the shape of the ultra-thin glass, so that the ultra-thin glass can be completely accommodated in the through hole and the whole is in a flat state. In the subsequent printing steps, the glass can be in a good state and can be moved smoothly from one end of the glass to the other end.

[0039] Optionally, the thickness of the contour plate 20 is 0.01-2 mm. The support fixture provided in this embodiment is used to support and carry ultra-thin glass and to perform coating printing on ultra-thin glass. Since the ultra-thin glass is relatively thin, it is preferable to provide a thinner contour plate 20 for position determination. The thickness of ultra-thin glass is generally around 100 μm or even thinner, and the corresponding thickness of the contour plate 20 is also relatively thin.

[0040] Furthermore, the profiling plate 20 is a steel plate. The profiling plate 20 required in the above embodiments is relatively thin, which needs to be matched with the thickness of the ultra-thin glass. It is preferable to use a steel plate as the profiling plate 20. This material can achieve a relatively thin thickness, and the processing technology is mature and convenient, so as to obtain a good fixture effect at a lower cost.

[0041] In this embodiment, the support plate 10 is preferably made of acrylic or metal. These materials make the support plate 10 easy to drill holes in, facilitating the setting of vacuum holes.

[0042] This application sets up a split support plate 10 and a contour plate 20 structure. By using a thinner material to prepare the contour plate 20 with specific through holes, the fixture can be adapted to ultra-thin glass of various shapes and sizes. The contour plate 20 is easy to obtain and has a low cost, which can meet the diverse needs of ultra-thin glass coating, control the cost of ultra-thin glass screen printing, and save more money.

[0043] It should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used above to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention; the directional terms "inner" and "outer" refer to the inside or outside relative to the outline of each component itself. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0044] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.
