For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figure 1-8 As shown, this utility model discloses a display backlight module bonding fixture, including a base 10. The upper surface of the base 10 is recessed with a first positioning groove 11 for positioning a CG cover plate 30. The bottom of the first positioning groove 11 is recessed with a second positioning groove 12 for positioning a FOG component 40. A step 13 is formed between the peripheral edge of the second positioning groove 12 and the first positioning groove 11.

[0034] At least one first clearance groove 14 is provided on both sides of the width direction A of the first positioning groove 11. For example, there are three first clearance grooves 14. The upper end of the first clearance groove 14 is open. The first clearance groove 14 is connected to the first positioning groove 11. The first electrical connection part 31 on the CG cover plate 30 can extend into the first clearance groove 14.

[0035] A second clearance groove 15 is provided on one side of the first positioning groove 11 along the length direction B. The upper end of the second clearance groove 15 is open. The second clearance groove 15 is connected to the first positioning groove 11 and the second positioning groove 12. The second electrical connection part 32 on the CG cover plate 30 and the third electrical connection part 41 on the FOG assembly 40 can extend into the second clearance groove 15.

[0036] A third clearance groove 16 is connected to one side of the second clearance groove 15. The upper end of the third clearance groove 16 is open, and the fourth electrical connection part 33 on the CG cover plate 30 can extend into the third clearance groove 16.

[0037] The first electrical connection part 31, the second electrical connection part 32, the third electrical connection part 41, and the fourth electrical connection part 33 are all flexible circuit boards.

[0038] The base 10 has notches 17 on both sides of the middle part. The notches 17 penetrate the upper and lower surfaces of the base 10. The two notches 17 are located on both sides of the width direction A of the first positioning groove 11. The notches 17 are connected to the first positioning groove 11 and the second positioning groove 12. By setting the notches 17, it is convenient for staff to pick up and put down the CG cover and FOG component 40.

[0039] The base 10 is provided with several support feet 18 below it.

[0040] The upper surface of the base 10 is provided with a plurality of guide blocks 20, which are distributed on the outer side of the first positioning groove 11. The guide blocks 20 facing the first positioning groove 11 have an inclined plane 21 and a vertical plane 22. The inclined plane 21 extends inclinedly from top to bottom towards the first positioning groove 11, and the lower edge of the inclined plane 21 extends to the vertical plane 22. The vertical plane 22 is flush with the inner wall surface 111 of the first positioning groove 11. By setting a plurality of guide blocks 20 on the outer side of the first positioning groove 11 and setting the inclined plane 21 and the vertical plane 22 on the surface of the guide blocks 20, when the operator puts the CG cover plate 30 into the first positioning groove 11, the peripheral edge of the CG cover plate 30 contacts the inclined plane 21 and the vertical plane 22, which can guide and correct the position of the CG cover plate 30, so that the CG cover plate 30 automatically aligns and falls accurately into the first positioning groove 11, thereby improving the fitting efficiency and accuracy of the CG cover plate 30.

[0041] The angle β between the inclined plane 21 and the horizontal plane is 55 degrees to 65 degrees, preferably 60 degrees; by adopting an angle β between the inclined plane 21 and the horizontal plane of 55 degrees to 65 degrees, the inclined plane 21 can better guide the CG cover plate 30.

[0042] The length L of the inclined plane 21 is 10mm to 30mm, preferably 20mm. The length direction B of the inclined plane 21 is defined as the length direction B or the width direction A of the first positioning groove 11. By using a length L of 10mm to 30mm for the inclined plane 21, the contact length between the edge of the CG cover plate 30 and the inclined plane 21 is longer, which is beneficial to the stability of the edge of the CG cover plate 30 when sliding relative to the inclined plane 21.

[0043] The width d of the inclined plane 21 is 2mm to 5mm, preferably 2.5mm, and the width direction A of the inclined plane 21 is defined as the inclination direction of the inclined plane 21.

[0044] The base 10 is provided with a third positioning groove 19. The inner wall of the third positioning groove 19, away from the first positioning groove 11, forms a positioning surface 191. The guide block 20 is installed in the third positioning groove 19, and the guide block 20 abuts against the positioning surface 191. By setting the third positioning groove 19, the guide block 20 abuts against the positioning surface 191 in the third positioning groove 19. When installing the guide block 20, the positioning surface 191 is used to position the guide block 20 to ensure the installation accuracy of the guide block 20, so that the vertical plane 22 on the guide block 20 is flush with the inner wall surface 111 of the first positioning groove 11.

[0045] The guide block 20 has two elongated holes 23 arranged side by side. The extension direction of the elongated holes 23 is parallel to the length direction B or width direction A of the first positioning groove 11. For example, in the guide blocks 20 located on both sides of the length direction B of the first positioning groove 11, the extension direction of the elongated holes 23 is parallel to the length direction B of the first positioning groove 11. The bottom of the third positioning groove 19 has a threaded hole 192. The screw passes through the elongated holes 23 and the threaded hole 192 in sequence, so that the guide block 20 can be detachably installed in the third positioning groove 19. By setting the elongated holes 23 on the guide block 20, during assembly, the positioning of the guide block 20 by the third positioning surface 191 is used as a reference. The threaded hole 192 is completely within the range of the elongated holes 23. Therefore, the elongated holes 23 provide a tolerance space for the screw axis to be aligned with the axis of the threaded hole 192, so that the screw can be accurately inserted into the threaded hole 192, which is convenient for assembly.

[0046] It should be noted that before bonding, glue or tape can be pre-applied to the CG cover plate 30 or FOG component 40.

[0047] In summary, this utility model provides a first positioning groove 11 and a second positioning groove 12 distributed vertically on the base 10, a first clearance groove 14 on both sides of the width direction A of the first positioning groove 11, and a second clearance groove 15 on one side of the length direction B of the first positioning groove 11. In use, the operator first positions the FOG component 40 in the second positioning groove 12 and places the third electrical connection part 41 in the second clearance groove 15. Then, the CG cover plate 30 is placed in the first positioning groove 11, with the first electrical connection part 31 in the first clearance groove 14 and the second electrical connection part 32 in the second clearance groove 15. Pressing down on the upper surface of the CG cover plate 30 will fix the CG cover plate 30 to the FOG component 40. This bonding fixture can simultaneously position the CG cover plate 30 and the FOG component 40, thereby improving positioning efficiency and bonding accuracy.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
