[0027] like Figure 1-4 As shown, this utility model discloses a display screen assembly adhesive application fixture, including a fixture body 10. The surface of the fixture body 10 is recessed with a first positioning groove 11 for positioning the display screen assembly 17, a second positioning groove 20 for positioning the adhesive tape, and a first clearance groove 12 for the FPC cable 18 of the display screen assembly to extend out. The first positioning groove 11, the second positioning groove 20, and the first clearance groove 12 are interconnected. The second positioning groove 20 is located on the side of the first positioning groove 11 near the first clearance groove 12. A positioning post 21 is provided on the second positioning groove 20, and the adhesive tape... The system includes a release film 23 and double-sided adhesive 25. The double-sided adhesive 25 is attached to one side of the release film 23. The release film 23 has positioning holes 24 corresponding to the positioning posts 21. The side of the release film 23 with the double-sided adhesive 25 faces the display assembly FPC cable 18. By setting a first positioning groove 11, a second positioning groove 20 and a first clearance groove 12 that are interconnected, and setting a positioning post 21 on the second positioning groove 20, and setting a positioning hole 24 on the release film 23 corresponding to the positioning post 21, the tape is positioned so that the tape is not offset and the problem of low work efficiency is solved.

[0028] The second positioning groove 20 has protrusions 22 at both ends along its length that avoid the double-sided adhesive 25. The protrusion height of the protrusions 22 is less than or equal to the thickness of the display assembly FPC cable 18. By setting the protrusions 22, when the tape is applied, if the tape is placed correctly, the double-sided adhesive 25 on the tape will be completely applied to the display assembly FPC cable 18. If the tape is placed incorrectly, the two ends of the double-sided adhesive 25 on the tape will be applied to the protrusions 22 to remind the staff that the tape is placed incorrectly, thereby avoiding tape application errors and improving product quality.

[0029] At least one end of the second positioning groove 20 along the length direction penetrates the side wall of the fixture body 10; the inner side wall of the end of the second positioning groove 20 that penetrates the fixture body 10 has a chamfer 26 at the junction with the fixture body 10; with this setting, it is easier to put the tape into the second positioning groove 20, thereby improving work efficiency.

[0030] In this invention, to further improve work efficiency, one or both ends of the release film 23 can protrude from the fixture body 10, making it easier to peel off the release film 23.

[0031] The fixture body 10 is also movably provided with a pressure plate 19 to prevent the display assembly FPC cable 18 from being pulled away from the first clearance groove 12 by the tape; the fixture body 10 is provided with a mounting block 191, and the pressure plate 19 is rotatably mounted on the mounting block 191; by setting the pressure plate 19, it is easy to prevent the display assembly FPC cable 18 from being pulled up when the release film 23 is peeled off.

[0032] The side of the first clearance groove 12 away from the first positioning groove 11 penetrates the side wall of the fixture body 10; this allows display assembly FPC cables 18 of different lengths to extend into the first clearance groove 12, improving versatility.

[0033] The first positioning groove 11 is provided with a plurality of guide blocks 16 on its periphery. The guide block 16 has a guide slope 161 on the side facing the first positioning groove 11 for guiding the display screen assembly 17. The fixture body 10 is also provided with a mounting groove 15 for mounting the guide blocks 16. By setting the guide blocks 16 and the guide slope 161, the display screen assembly 17 can be easily guided when it is placed into the first positioning groove 11, thereby improving work efficiency.

[0034] The first positioning groove 11 is provided with a second clearance groove 13 at each of the four inner corners; this can prevent the four corners of the display assembly 17 from contacting the inner wall of the first positioning groove 11 and causing damage.

[0035] The surface of the fixture body 10 is also recessed with a third clearance groove 14 to facilitate the placement and removal of the display screen assembly 17. The depth of the third clearance groove 14 is greater than the depth of the first positioning groove 11, and the third clearance groove 14 extends into the interior of the first positioning groove 11. This facilitates the placement or removal of the display screen assembly 17 from the first positioning groove 11, thereby improving work efficiency.

[0036] In this utility model, in order to further improve work efficiency, the third clearance groove 14 extends through the side wall of the fixture body 10 on the side away from the first positioning groove 11, which makes it easier for the staff to put the display screen assembly 17 into or take it out of the first positioning groove 11.

[0037] The method of using this utility model is as follows: Place the display assembly 17 into the first positioning groove 11 along the guide slope 161, and insert the display assembly FPC cable 18 into the first clearance groove 12. Use the positioning post 21 of the second positioning groove 20 and the positioning hole 24 on the release film 23 to position the tape into the second positioning groove 20, so that the double-sided adhesive 25 on the tape is attached to the display assembly FPC cable 18. Rotate the pressure plate 19 over the first clearance groove 12, peel off the release film 23, flip and open the pressure plate 19, and then use the third clearance groove 14 to take out the display assembly 17 that has been glued, thus completing the glue application work of the display assembly 17.

[0038] In summary, this utility model achieves the positioning of the tape by setting the first positioning groove 11, the second positioning groove 20 and the first clearance groove 12 to be interconnected, setting the positioning post 21 on the second positioning groove 20 and setting the positioning hole 24 on the release film 23 corresponding to the positioning post 21, so that the tape pasting position does not shift and the work efficiency is improved.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
