Description

Technical Field

[0001] The utility model mainly relates to the technical field of patch tooling, and particularly relates to a patch tooling for improving the strength of a screen assembly. Background Technique

[0002] At present, for the repair of the screen assembly, the coating process is carried out by attaching the screen assembly to the backplane. This method results in a significant reduction in the strength of the screen assembly after coating. By adjusting the tooling and trial production, it is clear that reducing the contact area between the screen assembly and the backplane can effectively improve the strength improvement route.

[0003] The inventor proposes a patch tooling for improving the strength of the screen assembly. Through the structural cooperation of the backplane strip, the guide pin and the first clamping seat, the pre-positioning before fixing the screen assembly is carried out through the sinking groove on the backplane strip. By manually adjusting the rotation of the first clamping seat outside the guide pin, the screen assembly is fixed on the backplane strip, reducing the contact area between the screen assembly and the bottom plate, and improving the coating yield rate of the screen assembly.

[0035] Referring to the attached Figures 1-4 , the present utility model provides a patch tooling for improving the strength of a screen assembly, including the following structures:

[0036] Bottom plate 1, on the top of the bottom plate 1, a back panel strip 2 is fixedly arranged, and a plurality of assembly holes 21 are fixedly arranged on the surface of the back panel strip 2.

[0037] Guide pin 3, a first card holder 4 is movably sleeved on the outside of the guide pin 3.

[0038] In this embodiment, a sunken groove 22 is fixedly provided above the assembly hole 21 of the backplane strip 2, and a plurality of positioning holes 23 are fixedly provided on the sunken groove 22. The positioning holes 23 are arranged in a circular pattern with the guide pin 3 as the center.

[0039] The structural design of the assembly hole 21 and the sunken groove 22 prevents the screen assembly from directly contacting the bottom plate 1. The positioning holes 23 are arranged around the guide pin 3. In combination with the first positioning tenon 5 or the second positioning tenon 8, the working position of the first card holder 4 or the second card holder 7 on the backplane strip 2 is limited. The arrangement of holes such as the assembly hole 21 and the sunken groove 22 on the backplane strip 2 facilitates the operator to place the screen assembly in place according to the operation requirements.

[0040] In this embodiment, a protruding portion is fixedly provided at the top of the guide pin 3, and the bottom of the guide pin 3 is fixed to the bottom of the inner wall of the sunken groove 22 of the backplane strip 2.

[0041] The setting of the protruding portion prevents the first card holder 4 or the second card holder 7 from falling off the guide pin 3.

[0042] In this embodiment, a first guide hole 41 that cooperates with the guide pin 3 is fixedly provided in the middle of the first card holder 4. First positioning tenons 5 are fixedly provided at the wide sides of the bottom of the first card holder 4. The bottom of the first positioning tenon 5 cooperates with the positioning hole 23. The length of half of the long side of the first card holder 4 is greater than the straight-line distance from the guide pin 3 to the top edge of the sunken groove 22.

[0043] The first card holder 4 rotates on the guide pin 3. The first positioning tenon 5 and the positioning hole 23 cooperate to complete the wide side of the first card holder 4 extending beyond the sunken groove 22 and reaching above the assembly hole 21, fixing the screen assembly above the assembly hole 21 of the backplane strip 2, facilitating subsequent coating processing of the screen assembly. By fixing the screen assembly with the first card holder 4 or the second card holder 7, it is possible to prevent the screen assembly from dropping pieces during the coating operation, prevent the screen assembly from directly contacting the bottom plate 1, and avoid problems such as reduced structural strength and abnormal liquid crystals in the screen assembly after coating production.

[0044] In this embodiment, a limiting spring 6 is clamped at the top of the guide pin 3. The bottom of the limiting spring 6 is clamped to the bottom of the inner wall of the second card holder 7. A second guide hole 71 is fixedly provided in the middle of the bottom surface of the second card holder 7. The second guide hole 71 cooperates with the guide pin 3 and the second guide hole 71 cooperates with the limiting spring 6.

[0045] Second positioning tenons 8 are fixedly provided at the wide sides of the bottom of the second card holder 7. The bottom of the second positioning tenon 8 cooperates with the positioning hole 23. The length of half of the long side of the second card holder 7 is greater than the straight-line distance from the guide pin 3 to the top edge of the sunken groove 22.

[0046] Based on the first card seat 4, the second card seat 7 is provided with a limiting spring 6 that cooperates with the guide pin 3. When the user lifts the second card seat 7 upward along the axial direction of the guide pin 3 and rotates it, the first card seat 4 fixes the screen assembly on the backplane strip 2. The limiting spring 6 ensures that the second card seat 7 does not move abnormally along the axial direction of the guide pin 3. The cooperation between the second guide hole 71 and the guide pin 3 ensures that the second card seat 7 slides along the axial direction of the guide pin 3 under the pulling of an external force.

[0047] The above-described embodiments merely represent certain implementation manners of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
