When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time. The terms "first", "second", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only embodiments.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] Refer to Figure 1 , Figure 2 , in an embodiment of the vehicle-mounted screen frame glue pressure-holding fixture, it includes a pressure-holding bottom frame 5 and a pressure-holding cover 4. The pressure-holding bottom frame 5 includes a frame dispensing rack 1, a bottom plate 3 and a bracket 2 connecting the frame dispensing rack 1 and the bottom plate 3. One side of the frame dispensing rack 1 away from the bottom plate 3 is movably connected to the pressure-holding cover 4. The frame dispensing rack 1 is provided with a positioning groove 12 and a clearance groove 121. The positioning groove 12 positions the casting backlight. The clearance groove 121 is arranged in the positioning groove 12 to clear the parts on the back of the casting. A material taking and placing groove 11 is also provided on the side of the frame dispensing rack 1.

[0026] In actual use, first clean the fixture, fix the pressure-holding base frame 5 on the dispensing machine platform, place the aluminum casting backlight into the positioning groove 12 of the frame dispensing rack 1, and the integrated spare parts on the back of the casting are correspondingly cleared from the clearance groove 121. After the dispensing machine adjusts the dispensing path and finishes dispensing, clean the edge of the cover plate of the fitting (the cover plate and the FOG screen bonded by OCA), then peel off the release film of the FOG screen, and at the same time peel off the release film of the aluminum casting backlight. Place the FOG screen of the fitting downward and assemble it with the aluminum casting backlight to complete the backlight assembly. Finally, take out the entire pressure-holding base frame 5 with the aluminum casting display screen, then place the pressure-holding cover 4 on the pressure-holding base frame 5 to apply pressure to the aluminum casting display screen.

[0027] Refer to Figures 3 - 6 , in an embodiment of the above-described embodiment, the frame dispensing rack 1 is pin-connected to the pressure-holding cover 4, and the frame dispensing rack 1 and the bottom plate 3 are connected by a T-shaped bracket 2. There are 4 T-shaped brackets 2, and on each horizontal part of each T-shaped bracket 2, there is a screw slot hole 21 on each side, and a first screw stud hole 22 is provided at the top of the vertical part.

[0028] In this embodiment, the connection structure of the bottom plate 3, the frame dispensing rack 1, and the pressure-holding cover 4 is as follows. The bottom plate 3 is provided with a second screw stud hole 31 that is docked with the screw slot hole 21 on the T-shaped bracket 2. The T-shaped bracket 2 is connected to the bottom plate 3 in an inverted T shape by using a screw to pass through the screw slot hole 21 and the second screw stud hole 31; at each position near the four corners of the frame dispensing rack 1, there is a connection slot 13. The upper part of the connection slot is a column part, and the lower part is a screw part. The T-shaped bracket 3 and the frame dispensing rack 1 are screwed and locked together by a screw passing through the first screw stud hole 22 and the screw part of the connection slot 13; at each of the four corners of the pressure-holding cover 4, there is a connection pin column 41 fixedly provided. Specifically, in this embodiment, it is an aluminum column. The aluminum column 41 is docked with the column part of the connection slot 13 on the frame dispensing rack 1 and is closed with the frame dispensing rack 1.

[0029] It should be noted that in other embodiments, the connection slot 13 can also be set as two slot holes, one slot hole connecting the bottom plate and the other slot hole connecting the pressure-holding cover, and the layout position of the slot holes can be arranged according to actual needs.

[0030] In this embodiment, the screw slot hole 21 on the T-shaped bracket 2 is preferably set as a nut step 211. The step design enables the screw to provide a greater torque when tightened and helps to reduce stress concentration, thereby increasing the strength and reliability of the fastening connection and ensuring the long-term stability of the connection.

[0031] In this embodiment, when the pressure-holding cover 4 and the frame dispensing jig 1 are closed, there is no contact between the bottom of the connecting pin column 41 and the screw cap inside the screw part. This non-contact design enables the fixture to reduce deformation or displacement caused by contact during single use, improving the connection accuracy; during long-term use, it can also reduce the performance degradation or failure caused by the contact wear between the two; and during use, it can reduce the possibility of loosening or failure caused by external factors such as vibration and impact, improving the overall stability of the system.

[0032] In this embodiment, each side of the fixture is provided with a pick-and-place slot 11 that is concave into the positioning slot 12, which is convenient for picking and placing materials in separate slots and the finished display screen after assembly.

[0033] In this embodiment, the bottom plate 3 is provided with a slot or component structure for connecting to the dispensing machine platform, which is convenient for fixing the fixture on the dispensing machine platform.

[0034] In summary, through the design of the positioning slot 12 and the clearance slot 121 on the frame dispensing jig 1 of the pressure-holding bottom frame 5 of the present utility model, the accurate positioning and assembly of the aluminum casting display module are realized. Through the movable connection structure design of the frame dispensing jig 1, the bottom plate 3, and the pressure-holding cover 4, the assembly force, the selection of fasteners, and the tightening torque can be better controlled, and the assembly sequence can be optimized to improve the rationality and accuracy of the assembly process.

[0035] The above-described embodiments merely represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
