Description
Technical Field
[0001] The utility model relates to the technical field of processing and manufacturing of liquid crystal display modules, and particularly relates to a disassembly tool for a glass cover plate of a liquid crystal display module. Background Art
[0002] With the rapid development of liquid crystal display module technology, it has been widely used in various electronic products, especially in consumer electronic products such as mobile phones, TVs, and tablet computers. In the structure of a liquid crystal display module, the glass cover plate, as an external protective layer, plays a crucial role. It not only protects the internal liquid crystal layer and circuit components but also directly affects the display effect.
[0003] In the production rework and subsequent maintenance processes of liquid crystal display modules, when it is necessary to disassemble the glass cover plate, the traditional method is to reduce the performance of the VHB tape by high - temperature or low - temperature means, and cooperate with a suction cup to suck the glass cover plate to separate the glass cover plate from the magnesium alloy backlight bracket. However, this method has obvious limitations: the high - temperature or low - temperature environment may cause deformation or damage to the magnesium alloy backlight bracket; the temperature change and mechanical stress during the disassembly process may cause scratches or even cracks on the glass cover plate; the high - temperature or low - temperature environment will also have a negative impact on the optical adhesive, which may lead to a decrease in the strength of the FOG and affect its adhesion effect. For the above reasons, the yield rate of using this disassembly method is only 20%, that is, a large number of modules cannot be successfully separated during the disassembly process, resulting in serious material losses.
[0004] Therefore, how to improve the existing disassembly method, increase the yield rate, and reduce the damage to each component has become a technical problem urgently to be solved in the industry. Summary of the Utility Model
[0005] In order to disassemble the glass cover plate more efficiently and safely, the utility model provides a disassembly tool for a glass cover plate of a liquid crystal display module.
[0006] The technical solution adopted by the utility model is as follows: a disassembly tool for a glass cover plate of a liquid crystal display module, including a plate body, the thickness of the middle part of the plate body is greater than the thickness of the four - week edge, and the four - week edge of the plate body forms an inclined beveled surface.
[0007] Preferably, the plate body has at least one acute angle.
[0008] Preferably, the plate body has at least one arc - shaped edge.
[0009] Preferably, the four - week edges of both the front and back sides of the plate body are provided with the beveled surfaces.
[0010] Preferably, the thickness at the outer edge of the inclined surface portion is less than 0.5 mm, the thickness of the plate body is 2 - 2.5 mm, and the included angle between the inclined surface portion and the plate body is 5 - 8°.
[0011] Preferably, it is made of high-strength plastic.
[0012] The utility model has the following beneficial effects: The disassembly tool proposed by the utility model, through reasonable design and corresponding disassembly methods, no longer relies on high-temperature or low-temperature environments, making the disassembly process of the liquid crystal display module more efficient, improving the success rate of disassembly, reducing material losses caused by disassembly failures, and thus reducing production costs.

[0018] The following further describes the utility model in conjunction with the embodiments and the drawings.
[0019] In the embodiment, as Figures 1 to 3 shown, it is a disassembly tool for the glass cover plate of a liquid crystal display module, including a plate body 1. The thickness of the middle part of the plate body 1 is greater than the thickness of the four peripheral edges, and the four peripheral edges of the plate body 1 form an inclined inclined surface portion 2. Three to four of these disassembly tools are required for the disassembly of the glass cover plate. The usage method is as follows: First, use the pointed parts of two disassembly tools to hold two corners of the non-bonded end (i.e., Figure 4The two warping points 7) in it warp up, and the VHB glue that fixes the glass cover plate 6 and the backlight bracket 5 has the stress point stickiness opened; then use the inclined surface part 2 of another disassembly tool to cut and separate the VHB glue in the gap where the glass cover plate 6 and the backlight bracket 5 are separated, that is, the disassembly operation is completed. The disassembly tool proposed by the present utility model, through reasonable design and corresponding disassembly methods, no longer relies on the influence of high-temperature or low-temperature environments, avoids the deformation and damage of the backlight bracket 5 made of magnesium alloy or other materials, and the design of the inclined surface part 2 of the tool can effectively reduce the mechanical stress on the glass cover plate 6, preventing scratches and cracks caused by temperature changes or mechanical factors, thereby ensuring the integrity of the glass cover plate 6. Compared with the 20% yield rate of the traditional method, after using the tool of this embodiment, the disassembly process of the liquid crystal display module becomes more efficient, improves the success rate of disassembly, reduces the material loss caused by disassembly failure, and thus reduces the production cost.
[0020] In the embodiment, as Figure 2 shown, the plate body 1 has at least one acute angle 3. The acute angle 3 forms a relatively sharp part, which is convenient for inserting to warp up the two warping points 7 at the non-bonded end of the glass cover plate 6, and the operation is more convenient.
[0021] In the embodiment, as Figure 2 shown, the plate body 1 has at least one arc-shaped edge 4. The arc-shaped edge 4 is mainly used in the step of cutting and separating the VHB glue. The arc-shaped edge 4 can extend into the liquid crystal display module internally to the minimum extent, avoiding damage to the internal film sheets.
[0022] In the embodiment, as Figure 3 shown, the four peripheral edges of both the front and back surfaces of the plate body 1 are provided with inclined surface parts 2. The existence of the inclined surface parts 2 can help the operator more easily insert the tool between the glass cover plate 6 and the backlight bracket 5, and effectively reduce the force required for disassembly, making the disassembly process smoother. In addition, this double-sided design improves the applicability and convenience of the tool, can be used flexibly on both sides, can adapt to different disassembly scenarios, thereby further improving the success rate and efficiency of disassembly and reducing damage to the components.
[0023] In the embodiment, as Figure 3 shown, the thickness d at the outer edge of the inclined surface part 2 is less than 0.5 mm, the thickness D of the plate body 1 is 2 - 2.5 mm, and the included angle β between the inclined surface part 2 and the plate body 1 is 5 - 8°. This precise thickness and included angle design enables the inclined surface part 2 to have better cutting-in ability, so as to be able to divide the VHB tape more effectively. The smaller outer edge thickness can more easily enter the narrow gap, reduce the pressure on the glass cover plate 6, and reduce the risk of scratching or cracking. At the same time, the specific included angle can also provide a better lever effect for the user, further making the disassembly process more efficient and safe.
[0024] In the embodiments, the disassembly tool is made of high-strength plastics, such as polycarbonate (PC) or polypropylene (PP). Making the disassembly tool of high-strength plastics has good strength and toughness, enabling it to effectively resist external pressure during disassembly without being easily deformed or damaged, and being able to complete the disassembly without damaging the glass cover plate 6 and other components.
[0025] Obviously, the above-mentioned embodiments of the present invention are merely examples for illustrating the present invention, rather than limitations on the implementation manners of the present invention. Other obvious changes or variations derived from the substantial spirit of the present invention still fall within the protection scope of the present invention.
