[0030] Example 1

[0031] An embodiment of the present application provides an assembly tool for a display module. Figure 1-6 The assembly tooling of the display module of the present application is described in detail. The assembly tooling of the display module includes:

[0032] The tooling body 1 is provided with an operating surface 2, the operating surface 2 is provided with a display screen placement groove 3, the bottom of the display screen placement groove 3 is provided with an air intake port 10, the air intake port 10 is connected with an air inlet 7 provided on the tooling body, and the air inlet 7 is used to connect an air intake device.

[0033] In this embodiment, a placement table 9 is arranged in the display screen placement groove 3 , an air suction groove 11 is arranged between the placement tables 9 , and an air suction port 10 is arranged at the groove bottom of the air suction groove 11 .

[0034] See also Figure 1-2The placement table 9 mainly includes four rectangular placement tables 9 and an annular placement table 9 around the inner side of the display placement groove 3. The suction groove 11 between the five parts of the placement table 9 is in the shape of a "field", and the suction port 10 is arranged in the middle.

[0035] In some other embodiments, the shape of the placement table 9 set in the display screen placement groove 3 can be any shape, and the position and number of the suction grooves 11 can also be adaptively adjusted so that the display screen 20 can be evenly adsorbed on the placement table 9 during suction.

[0036] In this embodiment, the tool body 1 is an aluminum profile, and the entire assembly tool is manufactured by CNC.

[0037] In this embodiment, in order to avoid direct contact between the display screen and the profile, a silicone pad 6 made of a softer material for backwashing is further arranged in the display screen placement groove 3. The silicone pad 6 is arranged on the placement table 9 and is adapted to the size of the placement table 9.

[0038] In this embodiment, a backlight placement groove 12 is further provided on the operation surface 2 and is located above the display screen placement groove 3 .

[0039] In this embodiment, the operating surface 2 is provided with limit blocks 8 for limiting the backlight 30 at intervals around the outer side of the backlight placement groove 12 , and a total of 8 limit blocks 8 are provided.

[0040] In this embodiment, an FPC placement slot 4 is further provided on the operation surface 2 , and the FPC placement slot 4 is used to place the FPC of the display screen 20 , where the FPC is a flexible circuit board.

[0041] In this embodiment, the tool body 1 is in a plate shape, and both sides of the tool body 1 are provided with discharge grooves 5 extending toward the inner side of the tool body 1 to the display screen placement groove 3. The discharge grooves 5 are used for assemblers to place the display screen 20 into the display screen placement groove 3 from both sides.

[0042] Furthermore, a clearance groove 13 is provided at the corner of the display screen placement groove 3 to prevent the four corners of the display screen 20 from contacting the corners of the assembly tooling, thereby causing the display screen 20 to break.

[0043] In this embodiment, the display screen 20 is a FOG screen, which means that the screen is original but the display cables of the screen are repaired, also called a pressed display screen.

[0044] See also Figure 4-6The method of using Example 1 of the present application is as follows: after cleaning the assembly tooling, connect the air intake device to the air intake port 7 through the air intake pipe; place the display screen 20 with the display surface facing downward and place the display screen 20 in the display screen placement slot 3, start the air intake device to absorb air, and then the air intake port 10 synchronously absorbs the air in the air intake slot 11, and evenly positions and adsorbs the display screen 20; hold the backlight 30, peel off the release film on the assembly surface of the backlight 30, and simultaneously peel off the release film of the polarizer on the back of the display screen 20, place the backlight 30 with the assembly surface facing downward in the backlight placement slot 12 and press down to complete the assembly of the display screen 20 and the backlight 30.
