Description

Technical Field

[0001] This utility model relates to the field of coating device technology, and in particular to a marble workbench surface structure. Background Technology

[0002] In LCD coating on a marble platform, the marble platform serves as a crucial support for the LCD glass. Typically, the LCD glass is fixed to the marble platform using negative pressure adsorption. To ensure more uniform and stable glass fixation, multiple adsorption grooves are usually used, arranged in a cross shape at the convergence point. Because LCD glass is generally only about 0.2-0.5mm thick, it is quite fragile. During negative pressure adsorption, the increased pressure at the cross-shaped convergence point easily leads to glass breakage. This is a very serious problem for LCD manufacturers. Utility Model Content

[0003] The purpose of this utility model is to provide a marble workbench surface structure to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A marble workbench structure includes a worktable panel. The top of the worktable panel is provided with a suction groove, which is composed of multiple grooves arranged in a crisscross pattern. The intersection of the grooves is arranged in an island-shaped structure. The top of the worktable panel is provided with multiple vertical through holes, the top of which are all connected to the suction groove.

[0006] By adopting the above technical solution, the intersection of the suction channels is changed from a direct intersection to an island-shaped structure, which increases the stress area at the intersection and reduces the risk of material breakage.

[0007] In a further embodiment, the island-shaped structure includes a cylindrical boss and an annular groove surrounding the cylindrical boss.

[0008] In a further embodiment, a rounded corner transition structure is provided at the connection between the air intake groove and the annular groove.

[0009] In a further embodiment, the top periphery of the platform is provided with multiple positioning grooves.

[0010] In a further embodiment, the periphery of the platform is provided with a blunted acute-angle structure.

[0011] In a further embodiment, the cross-section of the groove is arc-shaped.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. By changing the intersection of the suction channels from a direct intersection to an island-shaped structure, the stress area at the intersection is increased, which reduces the risk of material breakage. Attached Figure Description

Figure 1 In this specification, the terms "bottom surface" and "top surface," "inner" and "outer" refer to the direction toward or away from the geometry of a specific component. 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.

[0019] Example 1:

[0020] like Figures 1-2 As shown, a marble workbench structure includes a worktable 1. The top of the worktable 1 is provided with a suction groove 2, which is composed of multiple grooves arranged longitudinally and transversely. The intersection of the grooves is set as an island-shaped structure 3. The top of the worktable 1 is provided with multiple vertical through holes, the top of which are all connected to the suction groove 2. The island-shaped structure 3 includes a cylindrical boss and an annular groove surrounding the cylindrical boss. The connection between the suction groove 2 and the annular groove is provided with a rounded corner transition structure. The top periphery of the worktable 1 is provided with multiple positioning grooves. The periphery of the worktable 1 is provided with a blunted acute angle structure. The cross-section of the groove is arc-shaped.

[0021] Specific Implementation Process: In LCD coating on a marble platform, the marble platform is a crucial support for the LCD glass. Generally, negative pressure adsorption is used to fix the LCD glass on the marble platform. To ensure more uniform and stable glass fixation, multiple adsorption grooves are typically used, arranged in a cross shape at the confluence point. Because LCD glass is generally only about 0.2-0.5mm thick, it is very fragile. During negative pressure adsorption, greater pressure is generated on the glass at the cross confluence point, easily leading to glass breakage. This is a very serious problem for LCD manufacturers. This application's solution uses CNC machining to create the negative pressure channel, inventing an island-style intersection point. The airflow confluence point is innovatively changed from four confluence lines to three confluence lines, making the local pressure at the negative pressure airflow confluence point more gentle and reducing the probability of glass breakage.

[0022] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
