[0020] See also Figures 1 to 4 A display screen module inkjet fixture comprises a main body 1 for placing a display screen module, the area of ​​the upper surface of the main body 1 is larger than the area of ​​the upper surface of the display screen module, a pad 2 is provided between the upper surface of the main body 1 and the bottom surface of the display screen module, the area of ​​the upper surface of the pad 2 is smaller than the area of ​​the bottom surface of the display screen module, and positioning pieces are installed on the main body 1 at the four corners of the pad 2, and the positioning pieces are used to fix the display screen module. The main body 1 is used to support the display screen module. The main body 1 can be placed in the transport track. The area of ​​the main body 1 is larger than the area of ​​the display screen module, so that a gap can be left between the display screen module and the edge of the transport track to avoid paint accumulation on the side of the display screen module. At the same time, the module is completely exposed to facilitate inkjetting and ensure the quality of inkjetting. A pad 2 is provided on the upper surface of the main body 1 to raise the display screen module so that a gap is left between the display screen module and the main body 1 to avoid paint accumulation at the bottom of the display screen module. The area of ​​the pad 2 is smaller than the area of ​​the bottom shell of the module to avoid contact between the bottom of the module and the main body 1, further reducing the residual accumulation of paint. Positioning pieces are provided at the four corners of the pad 2 on the main body 1 to fix the display screen module to avoid shaking of the display screen module during transportation and ensure accurate inkjetting. The pad 2 can be integrally formed with the main body 1 or separately formed. The pad 2 is centrally arranged on the upper surface of the main body.

[0021] See also Figures 1 to 4Preferably, the positioning member includes four elastic blocks 3, and the four elastic blocks 3 are movably arranged at the four corners of the cushion block 2; or, two of the elastic blocks 3 are movably arranged at two opposite angles among the four corners of the cushion block 2, and the other two elastic blocks 3 are fixedly arranged at the remaining two opposite angles among the four corners of the cushion block 2. A mounting groove 11 is provided downwardly at the position where the elastic blocks 3 are arranged at the four corners of the cushion block 2 on the main body 1, and the elastic blocks 3 are installed in the mounting groove 11. It is convenient to install the elastic block 3. The center line of the mounting groove 11 in the horizontal direction bisects the angle of the cushion block 2 connected thereto. The positioning member also includes an elastic member 4 installed in the mounting groove 11, and the elastic member 4 is used to drive the elastic block 3 to clamp the display screen module placed on the main body 1. Since there are grooves on the bottom of the display module bottom shell, especially at the four corners (almost all types of module bottom shells have grooves at the four corners), the main body 1 is provided with elastic blocks 3 at the four corners of the cushion block 2 (two elastic blocks 3 can also be provided at the diagonals, and the other two are fixed), and the elastic blocks 3 are used to clamp the module and are also easy to disassemble.

[0022] See also Figures 1 to 3 Preferably, the elastic member 4 is arranged on a side of the mounting groove 11 close to the center of the cushion block 2, and the elastic block 3 is arranged on a side of the mounting groove 11 away from the center of the cushion block 2. One end of the elastic member 4 abuts against the end of the mounting groove 11 facing the cushion block 2, and a mounting hole 31 is provided in the elastic block 3 away from the end facing the cushion block 2, and the other end of the elastic member 4 penetrates into the mounting hole 31. Preferably, the elastic member 4 is a spring, or a silicone member. When the display screen module is installed, the module is pressed down, and the side of the module groove will squeeze the arc surface of the elastic block 3. The elastic block 3 is squeezed and pressed toward the center of the cushion block 2. When the display screen module is pressed into place, the elastic member 4 pushes the elastic block 3 to press the groove of the display screen module outward to complete the positioning and fixation of the display screen module.

[0023] See also Figure 2 , Figure 3 Preferably, a through slot 12 is provided downwardly on the bottom surface of the mounting slot 11, and a longitudinal positioning hole 32 is provided on the elastic block 3 at a position avoiding the mounting hole 31, and screws can be locked into the through slot 12 and the positioning hole 32. It is convenient to fix the elastic block 3 at the required position of the mounting slot 11, so that two elastic blocks 3 can be movable and the other two elastic blocks 3 can be fixed, and they can be fixed as needed.

[0024] See also Figures 1 to 4 Preferably, the end of the spring block 3 away from the center of the cushion block 2 is set to be arc-shaped. The end of the spring block 3 is arc-shaped to adapt to different types of module bottom shells and improve the application range of the fixture.

[0025] See also Figure 1 to Figure 2 Preferably, the upper surface of the cushion block 2 is provided with a plurality of through holes 13 penetrating the main body 1 downwards, so as to facilitate mechanical or manual lifting of the module from the bottom for disassembly, or the module can be sucked from the top for disassembly by a vacuum suction cup.

[0026] Preferably, the positioning member is a silicone member or a rubber member installed in the mounting groove 11, and does not need to be driven by a spring.
