Abstract
Description
Technical Field
[0001] The utility model relates to a simplified upper pressing device of an aluminum etching machine. Background Art
[0002] During the manufacturing process, LCD panels are etched using an aluminum etching machine. Traditional aluminum etching machines use a long-axis pressing method, which is highly susceptible to raindrop MURA. This causes the LCD panel to visually respond to different frequencies of light sources, resulting in perceived color differences, yield loss, and scrap. Long-axis occlusion can also easily cause uneven etching of the glass. Therefore, improvements were necessary to address these issues, leading to the development of this project.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0016] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.
[0017] like Figures 1 to 4 As shown, the utility model is a streamlined upper pressure device for an aluminum etching machine, which is used to cooperate with a receiving device located below the starting device to form a transmission mechanism of the aluminum etching machine. The streamlined upper pressure device is intended to reduce the problems caused by uneven etching of the substrate and the generation of MURA, improve the operational stability of the upper pressure device, and reduce the risk of product fragmentation. The specific structure includes multiple upper pressure shafts 1 arranged in parallel above the panel to be etched, and each upper pressure shaft 1 is equipped with a roller 2. The upper pressure shaft 1 adopts a short-axis type, and the front and rear ends of the upper pressure shaft 1 along the axial direction are respectively equipped with bearing nests 3, and the bearing nests 3 are suspended and installed on the upper pressure bracket 4. The bearings at the front and rear ends of the short-axis upper pressure shaft adopt two suspended bearing nests, which make it more convenient to install the bearing nest into the machine, and can reduce the influence of tolerance, adjust the center of gravity, and reduce the fragmentation caused by the mechanism.
[0018] In this embodiment, the bearing nest 3 is vertically slidably engaged with the upper pressure bracket 4. Specifically, the bearing nest 3 is located inside the upper pressure bracket 4, and has vertical slide grooves 8 at both ends of the bearing nest 3. The upper pressure bracket has vertical guide rails 9 at both ends of the interior, and the vertical guide rails are slidably engaged with the vertical slide grooves.
[0019] In this embodiment, the upper pressing bracket 4 is vertically installed on the machine table 5 of the aluminum etching machine.
[0020] In this embodiment, a vertically arranged adjusting screw 6 is installed in the middle of the upper end of the upper pressure bracket 4. The adjusting screw 6 is threadedly connected to the bearing nest 3. When the adjusting screw 6 is rotated, the bearing nest 3 is driven to move up and down along the upper pressure bracket 4.
[0021] In this embodiment, the upper pressing bracket 4 is made of PEEK. Aluminum etching liquid is a mixture of nitric acid, acetic acid and phosphoric acid, which is highly acidic. The upper pressing bracket is made of PEEK, which effectively reduces corrosion by the aluminum etching liquid.
[0022] The advantages of the present invention are as follows: (1) the bearings at the front and rear ends of the short-axis upper pressure shaft are nested with two suspended bearings, which makes it easier to install the nested bearings into the machine and reduces the influence of tolerances, adjusts the center of gravity, and reduces the risk of fragmentation caused by the mechanism; (2) the operating stability of the upper pressure device is improved without affecting the original transmission efficiency, effectively improving the stability of glass transmission and reducing the impact of the mechanism on the product; (3) the aluminum etching liquid is a mixture of nitric acid, acetic acid, and phosphoric acid with a strong acidity, and the upper pressure bracket is made of PEEK material, which effectively reduces corrosion by the aluminum etching liquid; (4) the generation of MURA caused by uneven etching of the substrate is reduced, the scrap rate is reduced, the yield rate is improved, and the frequency of product abnormalities such as MURA, CD abnormalities, and fragmentation is reduced.
[0023] This streamlined press device is designed to reduce the MURA / etching unevenness caused by the traditional press shaft due to the special transmission mechanism during the panel ETCH process, reduce the fragmentation caused by the mechanism, and is easy to install, improving the durability and stability of the press.
[0024] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integrated molding process).
[0025] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.
[0026] Any component provided by the present invention can be assembled from multiple separate components, or can be a separate component manufactured by an integral forming process.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for protection of the utility model.
