DETAILED DESCRIPTION

[0033] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 8 The present invention provides a technical solution: a liquid crystal display processing device, including a positioning frame 2, two side frames 3 and a movable frame 4.

[0035] The positioning frame 2 and the side frame 3 are respectively provided with a limiting groove 22 and a screen groove 7 for the display screen 1 to be inserted.

[0036] The movable frame 4 can be inserted into and fixed on the side frame 3 and seal the display screen 1 .

[0037] The limiting groove 22 can limit the display screen 1 and allow a glue coating gap to exist between the edge of the display screen 1 and the upper and lower inner walls of the screen groove 7 .

[0038] A first glue injection component is installed inside the side frame 3 to fill the glue coating gap with glue A.

[0039] It includes a second glue injection component for filling the glue coating gap with glue B, and can seal the glue coating gap.

[0040] Among them, glue A and glue B can be mixed to harden and bond.

[0041] The difference between the present invention and the prior art is that when the display screen 1 is glued and packaged, a process of first installing and then injecting glue is adopted, so that the bonding part can be effectively filled with a sufficient amount of glue, thereby improving the stability and sealing of the bonding.

[0042] See also Figure 4 and Figure 5The present invention provides different limiting grooves 22 and screen grooves 7, so that when the display screen 1 is inserted into the middle positioning frame 2 and the side frame 3, the limiting grooves 22 can limit the display screen 1, so that a glue gap can be formed between the front and back surfaces of the display screen 1 and the inner wall of the screen groove 7. When glue exists in the glue gap, the edge portion of the display screen 1 and the portion in contact with the inside of the screen groove 7 can be effectively adhered and fixed to each other. Secondly, by injecting glue afterwards, the glue gap can be effectively filled, thereby improving the stability of adhesion and the sealing performance of the connection.

[0043] Secondly, the present invention forms glue liquid by setting a mixture of glue A and glue B, which can avoid the glue liquid solidifying in the glue channel and causing blockage. Glue A and glue B are liquid when they exist alone and can be stored for a long time. However, when glue A and glue B are mixed, glue A and glue B will harden and adhere to each other, thereby making the edge part of the display screen 1 adhere to the inside of the screen groove 7 to achieve sealed packaging.

[0044] Furthermore, a second sealing strip 14 is installed on the inner wall of the limiting groove 22, and an installation groove 21 is opened on the inner wall of the side frame 3. The installation groove 21 is connected to the screen groove 7, and a first sealing strip 13 is fixedly adhered to the inner wall of the installation groove 21. The first sealing strip 13 is a convex structure, and the convex structure of the first sealing strip 13 is inserted into the interior of the screen groove 7.

[0045] Through the cooperation between the second sealing strip 14 and the first sealing strip 13, the outer wall of the display screen 1 inserted into the positioning frame 2 and the side frame 3 can be sealed and protected, and buffering capacity is provided at the same time. The first sealing strip 13 and the second sealing strip 14 can be fixed by adhesion or snap-fitting.

[0046] Among them, a more preferred embodiment is that the first glue injection component includes a first glue storage chamber 9 opened inside the side frame 3, a piston plate 11 is slidably installed on the inner wall of the first glue storage chamber 9, a plurality of capillaries are opened between the inner wall of the first glue storage chamber 9 and the inner wall of the screen groove 7, and the plurality of capillaries are distributed in an array manner, and a glue injection port 20 connected to the interior of the first glue storage chamber 9 is opened on the outer wall of the side frame 3, including a transmission component for injecting glue A in the first glue storage chamber 9 into the glue coating gap through the capillaries.

[0047] See also Figure 4 and Figure 8 The capillaries are not shown in the drawings of the present invention, but are explained in this embodiment. The capillaries serve as a connecting bridge and can connect the first glue storage cavity 9 with the glue coating gap, so that the glue A inside the first glue storage cavity 9 can enter the glue coating gap. Secondly, the capillaries can reduce the holes in the side frame 3 without affecting the firmness of the side frame 3. Thirdly, the capillaries distributed in an array can fill the glue A in the glue coating gap more evenly.

[0048] When the glue A in the first glue storage chamber 9 is squeezed, the glue A will transfer to the side with lower pressure through the capillaries.

[0049] After the display screen 1 is installed, glue A is injected into the first glue storage cavity 9 through the glue injection port 20 , and then the display screen 1 is sealed by the movable frame 4 .

[0050] Based on the first glue injection assembly embodiment, the transmission assembly includes an assembly hole 8 opened on the side frame 3, the assembly hole 8 is communicated with the interior of the first glue storage chamber 9, the inner wall of the assembly hole 8 is threadedly connected with a hexagon socket bolt 6, and the end of the hexagon socket bolt 6 is rotatably connected to the outer wall of the first glue storage chamber 9. When the hexagon socket bolt 6 rotates, the up and down movement of the piston plate 11 can be controlled.

[0051] For more details, please refer to Figure 4 and Figure 5 By providing the assembly hole 8 and the hexagon socket bolt 6, concealed installation can be achieved, thereby preventing the hexagon socket bolt 6 from being exposed to the outside.

[0052] When the glue liquid in the first glue storage cavity 9 needs to be squeezed out, the hexagon socket bolt 6 can be rotated so that the piston plate 11 can apply pressure downward to the glue A, thereby completing the glue injection into the glue coating gap.

[0053] Based on the first glue injection component embodiment, the second glue injection component includes an independent glue injection body 5, and a protrusion 12 extends outward from the bottom of the glue injection body 5, and the protrusion 12 can be inserted into the glue coating gap. A second glue storage cavity 23 is opened inside the glue injection body 5, and the protrusion 12 is connected to the interior of the second glue storage cavity 23, and the protrusion 12 is connected to the glue coating gap, so that the B glue inside the second glue storage cavity 23 can flow through the protrusion 12 to the glue coating gap and mix with the A glue, including a pump component for injecting high-pressure B glue into the second glue storage cavity 23.

[0054] For more details, please refer to Figure 5 By setting the protruding nozzle 12, the glue coating gap can be closed to avoid outward leakage when injecting glue A. Its main function is to inject glue B into the coating gap. Since the injection body 5 exists independently, the injection body 5 can be reused.

[0055] The present invention also provides a second embodiment. Since the thickness of the glue coating gap is very thin, the protruding nozzle 12 is easily damaged when the injection body 5 is pulled out. This embodiment can make the protruding nozzle 12 easily separated from the injection body 5. Therefore, it is necessary to treat the protruding nozzle 12 and the injection body 5 as two independent entities, so that the protruding nozzle 12 can be better and not easily deformed and retained in the coating gap, which can avoid the leakage of glue and improve the sealing performance there.

[0056] Furthermore, after hardening is completed, the injection body 5 is pulled out, and a rubber strip is inserted into the outermost layer of the glue coating gap.

[0057] Furthermore, two flanges 18 are fixedly installed on the outer wall of the movable frame 4, and a third sealing strip 15 matching the display screen 1 is adhered between the two flanges 18. A plurality of spline pins 16 are fixedly installed on the outer wall of the movable frame 4, and a plurality of spline grooves 19 are provided on the outer wall of the side frame 3. The spline pins 16 are plugged into the spline grooves 19, and the interior of the spline grooves 19 is filled with hot melt adhesive. A piston column 17 is also fixedly installed on the outer wall of the movable frame 4. When the movable frame 4 is docked with the side frame 3, the piston column 17 can be inserted into the interior of the glue injection port 20 to seal it.

[0058] See also Figure 6 and Figure 7 , wherein the structure of the spline pin 16 enables it to have a strong limiting ability, secondly, the spline setting of the spline pin 16 can increase its surface area, and the wavy outer surface is more conducive to the adhesion of the glue, so that the movable frame 4 can be better connected to the side frame 3, wherein the cross-section of the spline groove 19 is larger than the cross-section of the spline pin 16, so that the glue can exist better, secondly, the excess glue will penetrate outward when squeezed, so that glue is also left between the outer walls of the side frame 3 and the movable frame 4 that are in contact, thereby improving its stability.

[0059] The A glue in the present invention is a hard liquid hardener, and the B glue is a liquid glue.

[0060] Furthermore, the display screen 1 and the two side frames 3 are made in one piece by an injection mold.

[0061] In summary, the present invention adopts the method of sealing the frame first and then injecting glue for packaging, which can effectively improve the stability and sealing performance of the glue, thereby improving the waterproof and dustproof capabilities of the display screen 1.

[0062] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
