[0002] With the rapid development of electronic liquid crystal display modules towards light, thin and miniaturized, various portable electronic liquid crystal display modules almost all use liquid crystal displays as display terminals, and liquid crystal displays have become important components. A liquid crystal display module is the main component of a liquid crystal display, mainly including components such as a metal frame, a display panel and a backlight module. The metal frame and the backlight module form a liquid crystal display module by combining the display panel through a snap structure.

[0003] Currently, when disassembling a liquid crystal display module for return to the factory, it is necessary to disassemble the metal frame from the backlight module. Most of the existing operation methods use auxiliary tools such as blades or tweezers for disassembly operations. However, during the disassembly process, the blade is thin and easy to break, and the blade edge is relatively sharp, which is easy to scratch the hand and other parts, causing personal injury and damage to the backlight module; while the tweezers cannot be inserted into the metal frame during the disassembly process because the thickness of the body is greater than the gap between the metal frame and the backlight module, resulting in breakage and waste of the tweezers, and there are shaving residues on the tweezers, which affect the quality of the liquid crystal display module. Therefore, the existing disassembly methods cannot meet the actual needs. Summary of the Utility Model

Specific implementation mode

[0024] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application.

[0025] The utility model provides a rework fixture for a metal frame of a liquid crystal display module, so as to solve the problems in the prior art that the metal frame and the backlight module are easily damaged during the rework of the metal frame, and the manufacturing cost is increased.

[0026] For the convenience of understanding, the specific process in the embodiments of this application will be described below. Please refer to Figures 1 to 3 A rework fixture for a metal frame of a liquid crystal display module in an embodiment of this application includes a liquid crystal display module 1, a bottom plate 2, a limiting component 3, a shaping component 4 and a disassembly part 5; the liquid crystal display module 1 includes a display panel 11 embedded in a backlight module 10, the upper surface of the backlight module 10 is connected by clamping with a metal frame 12, and a gap 13 is provided between both sides of the metal frame 12 and the backlight module 10. At the same time, the metal frame 12 limits the display panel 11 in the backlight module 10; the limiting component 3 is arranged on the bottom plate 2 to limit the inverted liquid crystal display module 1; the shaping component 4 is installed on the bottom plate 2 and is located around the liquid crystal display module 1 to perform four-sided shaping on the metal frame 12 located in the limiting component 3; the disassembly part 5 includes a disassembly body 50, and a disassembly tool bit 51 inclined to the disassembly body 50 extends from the lower surface of the disassembly body 50, and the thickness of the disassembly tool bit 51 is smaller than the width of the gap 13. The disassembly tool bit 51 is used to insert into the gap 13 and then manually separate the metal frame 12 and the backlight module 10.

[0027] The rework fixture for the metal frame of the liquid crystal display module of the present utility model can quickly and effectively separate the metal frame 12 connected to the backlight module 10 by inserting the split tool heads 51 inclined in the split part 5 into the two gaps 13 respectively and then manually. In this way, the separated metal frame 12 and backlight module 10 are not damaged. And the split metal frame 12 is four-sided shaped by the shaping component 4, realizing the rework disassembly of the metal frame 12 quickly, improving the yield rate of the disassembled metal frame 12, reducing the injuries caused by operators during the operation process, and cutting down the manufacturing cost.

[0028] Furthermore, in this embodiment, since the liquid crystal display module 1 is arranged upside down on the bottom plate 2, the metal frame 12 is arranged on the bottom 2 at this time. Therefore, the limiting component 3 includes two limiting blocks 30 arranged along the diagonal of the metal frame 12, and the limiting blocks 30 are in an L shape. Since the two L-shaped limiting blocks 30 are arranged diagonally on both sides of the diagonal of the metal frame 12, the four sides of the metal frame 12 are limited, and the limiting is convenient and accurate.

[0029] Furthermore, the shaping component 4 includes four shaping cylinders 40 arranged on the four sides of the metal frame 12; a shaping plate (not shown in the figure) parallel to one side of the corresponding metal frame 12 is provided at the front end of the shaping cylinder 40, and the shaping plate is arranged along the length direction of the metal frame 12. In this way, when the shaping cylinder 40 works, the shaping cylinder 12 effectively shapes the four sides of the metal frame 12 by pushing the shaping plate. The reason for shaping is that when the split part 5 is used to split the metal frame 12 and the backlight module 10, the metal frame 12 may be deformed to a certain extent. The shaping cylinder 12 can shape the four sides of the metal frame 12 to a certain degree so that the metal frame 12 can meet the usage requirements after rework.

[0030] Furthermore, in this example, the number of the split parts 5 is two, and the two split parts 5 are respectively arranged in the left gap 13 and the right gap 13 between the metal frame 12 and the backlight module 10. At this time, the split tool head 51 of the first split part 5 can be inserted into the left gap first to separate the left side between them first, and then the split tool head 51 of the other split part 5 is inserted into the right gap to separate the right side between them. Finally, the operator quickly separates the metal frame 12 as a whole from the backlight module 10.

[0031] Furthermore, the material of the split part 5 is stainless steel, which can improve its service life and reduce costs.

[0032] Further, in this embodiment, the gap between the metal frame 12 and the backlight module 10 is between 0.3 mm and 0.5 mm. Therefore, the thickness of the splitting tool head 51 is designed to be between 0.3 mm and 0.4 mm at this time. Only when the thickness of the splitting tool head 51 is less than the distance of the gap 13, the splitting tool head 51 can be inserted into the gap, so as to conveniently separate the metal frame 12 and the backlight module 10 that are clamped together.

[0033] In addition, the splitting body 50 and the splitting tool head 51 are inclined, which is also to facilitate the splitting tool head 51 to be smoothly inserted into the gap 13 and facilitate the separation of the metal frame 12 and the backlight module 10. The inclination angle between them is between 10° and 15°, and can be adjusted according to the actual situation.

[0034] During specific actual use:

[0035] The first step: Invert the liquid crystal display module 1 and place it on the bottom plate 2, and limit the four sides of the metal frame 12 through two L-shaped positioning blocks 30;

[0036] The second step: First, insert the splitting tool head 51 of the first splitting part 5 into the gap on one side of the metal frame 12 and the backlight module 10, manually separate the metal frame and the backlight module 10 on one side, and then insert the splitting tool head 51 of the other splitting part 5 into the gap 13 on the other side of the metal frame 12 and the backlight module 10, and manually separate the fitting bayonet of the metal frame 12 from the other side of the backlight module 10, so as to separate the whole metal frame 12 from the backlight module 10;

[0037] The third step: After the metal frame 12 is separated from the backlight module 10, take out the backlight module 10 and put the two splitting parts 5 back to their original places;

[0038] The fourth step: The four shaping cylinders 40 start to work, drive the four shaping plates to push towards the four sides of the metal frame 12, so as to shape the outside of the metal frame and ensure that the metal frame can be reworked and reused.

[0039] In summary, after using this fixture, the risk of safety accidents is reduced, and the qualified rate of the reworked metal frame is increased from 50% to 96%, thus reducing a certain use cost.

[0040] The above is the case. The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
