[0003] During the assembly process of the display screen, liquid optically transparent adhesive is required to connect the display screen to the fixed plate. The existing technology uses a bakelite jig for positioning. The glue thickness during bonding is completely controlled by parameters such as the air pressure of the debugging equipment. Factors such as cumbersome debugging and poor equipment operation stability result in uneven glue thickness of the product, resulting in the total thickness of the product exceeding the standard, a high probability of rework, and affecting production efficiency. Therefore, a full-fitting height-limited display screen mounting assembly is needed. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] The utility model presses the liquid crystal screen body and the liquid optically transparent adhesive layer by arranging a cover plate and placing it inside the placement groove. The distance between the bottom surface of the cover plate facing the liquid crystal screen body and the liquid crystal screen body is the same as the thickness of the liquid optically transparent adhesive layer.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figures 1 to 4 , the utility model provides a technical solution:
[0020] A fully-fitted height-limited display screen mounting assembly comprises a base plate 1, a liquid optically transparent adhesive layer 6, a functional sheet 7 and a cover plate 4. A placement groove 2 is provided on the surface of the base plate 1, a plurality of ventilation holes 10 are provided on the inner bottom surface of the placement groove 2, bumps 3 are provided on both sides of the outer wall corners in the middle of the placement groove 2, a plurality of fixing holes 5 are provided on the surface of the base plate 1 on the outer sides of the placement groove 2, and the inner bottom surface of the cover plate 4 is slidably connected to the placement groove 2 provided on the surface of the base plate 1.
[0021] The cover plate 4 is provided to be slidably connected to the inner wall of the placement groove 2 provided on the surface of the base plate 1, and a plurality of ventilation holes 10 are provided on the inner bottom surface of the placement groove 2 to dissipate heat from the liquid optically transparent adhesive layer through the ventilation holes 10, thereby ensuring the service life of the liquid crystal screen body 9. At the same time, a plurality of fixing holes 5 are provided on the surface of the base plate 1 outside the placement groove 2 to facilitate fixing the cover plate 4 and the base plate 1, thereby facilitating the perfusion of the liquid optically transparent adhesive layer 6 onto the surface of the liquid crystal screen body 9. The thickness of the liquid optically transparent adhesive layer 6 is controlled by the distance between the cover plate 4 and the liquid crystal screen body 9, thereby avoiding the need to repeatedly adjust the thickness of the liquid optically transparent adhesive layer 6 through external equipment.
[0022] The liquid optically transparent adhesive layer 6 is in contact with the inner bottom surface of the placement groove 2 and the side wall of the functional sheet 7. By setting the liquid optically transparent adhesive layer 6 in contact with the inner bottom surface of the placement groove 2 and the side wall of the functional sheet 7, the functional sheet 7 is fixed to the inner bottom surface of the placement groove 2 by the liquid optically transparent adhesive layer 6, thereby preventing the functional sheet 7 from falling from the inside of the liquid optically transparent adhesive layer 6.
[0023] The other side of the functional sheet 7 is adhered to the bottom surface of the liquid crystal screen body 9 through the optical adhesive layer 8, and the other side of the functional sheet 7 is adhered to the bottom surface of the liquid crystal screen body 9 through the optical adhesive layer 8, so that the functional sheet 7 and the liquid crystal screen body 9 are adhered to each other through the optical adhesive layer 8, and the functional sheet 7 is fixed to one side of the liquid crystal screen body 9 to ensure the normal use of the liquid crystal screen body 9.
[0024] The thickness of the cover plate 4 between the placement groove 2 and the liquid crystal screen body 9 is the same as the thickness of the liquid optically transparent adhesive layer 6. By setting the thickness of the cover plate 4 between the placement groove 2 and the liquid crystal screen body 9 to be the same as the thickness of the liquid optically transparent adhesive layer 6, the thickness of the liquid optically transparent adhesive layer 6 can be limited by the distance between the cover plate 4 and the placement groove 2, thereby avoiding uneven thickness of the liquid optically transparent adhesive layer 6 resulting in excessive total thickness of the product, increased rework efficiency due to full bonding, and low production efficiency.
[0025] The combined thickness of the cover plate 4 , the liquid optically transparent adhesive layer 6 , the functional sheet 7 , the optical adhesive layer 8 and the liquid crystal screen body 9 is the same as the inner depth of the placement groove 2 .
[0026] By setting the combined thickness of the cover plate 4, the liquid optically transparent adhesive layer 6, the functional sheet 7, the optical adhesive layer 8 and the liquid crystal screen body 9 to be the same as the internal depth of the placement groove 2, the thickness of the liquid optically transparent adhesive layer 6 injected into the interior can be limited by controlling the distance between the cover plate 4 and the liquid crystal screen body 9. In this way, the thickness of the liquid optically transparent adhesive layer 6 is limited, the rework rate caused by the uneven thickness of the adhesive when the liquid crystal screen body 9 is fully bonded, the total thickness of the product exceeding the standard, the labor rework cost, and the production efficiency are increased.
[0027] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
