[0022] Embodiment 1

[0023] In this embodiment, the present utility model provides a display repair and disassembly device, which can disassemble the display screen, improve the disassembly efficiency, and is not easy to damage the components.

[0024] As Figures 1-3 shown, in an embodiment of the present utility model, the display repair and disassembly device of the present utility model for disassembling the display screen includes a base 1, a disassembly platform 2, and a disassembly top plate 3. The base 1 is provided with control buttons and switches. The disassembly platform 2 is arranged on the base 1. On the front side of the disassembly platform 2, a first guide rod 4 and a second guide rod 5 are arranged at intervals left and right. On the top surface of the disassembly platform 2, a plurality of suction holes 6 are provided. A vacuum pumping structure (a mature existing technology, not shown in the figure) is connected to the side of the disassembly platform 2, and the vacuum pumping structure is connected to the plurality of suction holes 6. A heating structure (a mature existing technology, not shown in the figure) is arranged inside the disassembly platform 2, and the heating structure is used to heat the disassembly platform 2. The temperature range for the heating structure to heat the disassembly platform 2 is 50-70 °C. Heating the disassembly platform 2 to this temperature is helpful for the disassembly of the display screen. The base 1 is also provided with a display screen for displaying the temperature of the disassembly platform 2, which can display the temperature of the disassembly platform 2 in real time. The disassembly top plate 3 is arranged above the disassembly platform 2 and sleeved on the first guide rod 4 and the second guide rod 5. A plurality of first through holes 7 are provided on the disassembly top plate 3, and the first through holes 7 are used to connect the side of the backlight frame of the display screen. A plurality of second through holes 8 are provided at the edge of the disassembly top plate 3, and disassembly screws 9 are arranged in the second through holes 8. The disassembly screws 9 are used to cooperate with the disassembly platform 2 to complete the disassembly of the display screen. The disassembly screws 9 are hand-twist plum blossom screws. More specifically, the disassembly screws 9 are hand-twist plum blossom top screw rods.

[0025] The utility model is particularly applicable to the disassembly of in-vehicle displays. Continuing with the example of a 14.6-inch in-vehicle display of BOE, the specific application disassembly process of the utility model will be elaborated in detail. Before using the utility model, the disassembly top plate 3 is separated from the disassembly platform 2. Then, before specific use, confirm the specific state of the utility model. Then, observe the temperature of the disassembly platform 2 through the display screen on the base 1. The top surface of the disassembly platform 2 is a Teflon surface. Observe whether there is wear on this Teflon surface. If necessary, perform treatment. After confirming the state of the utility model, place the display screen on the top surface of the disassembly platform 2 so that the CG board of the display screen is aligned with the suction hole 6. Then, take the disassembly top plate 3 and assemble the disassembly screw 9 in the second through hole 8 on the edge of the disassembly top plate 3. Then, align the disassembly top plate 3 with the first guide rod 4 and the second guide rod 5 and sleeved the disassembly top plate 3 on the first guide rod 4 and the second guide rod 5. It can be understood that the first through hole 7 of the utility model corresponds to the screw hole on the side of the backlight frame of the display screen (the backlight frame of the display screen itself has through holes). After sleeving the disassembly top plate 3, take a screw and pass it through the first through hole 7 and extend it into the screw hole on the side of the backlight frame of the display screen. This screw is specifically an internal hexagonal screw. At this time, the internal hexagonal screw is only pre-locked and not locked. Then, arrange the PCB board and FPC flexible board and other structures of the display screen so that these structures extend outside the utility model. Then, turn on the vacuum pumping structure and adsorb the CG board of the display screen through the suction hole 6. Then, lock the internal hexagonal screw. Then, turn the disassembly screw 9 in sequence. The disassembly screw 9 passes through the disassembly top plate 3 until it touches the disassembly platform 2. Continue to turn the disassembly screw 9. The disassembly screw 9 and the disassembly top plate 3 cooperate with each other (refer to the lead screw principle) to lift the disassembly top plate 3 upward and drive the side of the backlight frame of the display screen upward to separate from the CG board of the display screen. Turn all the disassembly screws 9 in sequence, and the backlight frame of the display screen and the CG board of the display screen are successfully separated. During the overall use process, the various structures of the display screen will not be damaged. The design is reasonable and the structure is simple.

[0026] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the utility model shall fall within the protection scope of the technical solution of the utility model.
