Technical Field

[0003] After searching, the application with patent number 201720767451.7 discloses a liquid crystal module fixing structure. The liquid crystal module includes a front frame, a display panel, and a backlight module from top to bottom. The display panel includes an upper polarizer and a lower polarizer. The backlight module includes a middle frame and a back plate. The display panel and the backlight module are closely adjacent. The lower polarizer of the display panel has a through hole. The middle frame of the backlight module is provided with a retaining wall. The retaining wall fixes the display panel and the backlight module through the through hole. The utility model also discloses a liquid crystal module including the liquid crystal module fixing structure. The liquid crystal module is not only easy to assemble and disassemble, but also less likely to damage the diaphragm during assembly and disassembly of the liquid crystal module, thereby improving the yield rate.

[0004] However, in the existing process of fixing LCD modules, it is generally necessary to use iron frame feet to twist them. However, in the existing operation process, the iron frame foot twisting operation has certain requirements on personnel skills, and the training of operators requires a long period of time, causing the company to spend a lot of manpower and material training costs. Secondly, the iron frame foot twisting operation will cause unnecessary labor cost expenditures for the future realization of automated operations.

[0005] Therefore, we propose an iron frame with twist-free feet to fix the LCD module. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the utility model provides an iron frame without twisting feet to fix the liquid crystal module, which solves the problems of the existing iron frame conductive rubber twisting feet type clamping and fixing operation being cumbersome, difficult and low in fixing efficiency.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: an iron frame with twist-free pins for fixing a liquid crystal module, comprising an LCD panel conductive rubber and a PCBA conductive rubber conductively connected thereto, a BL conductive rubber being installed between the LCD panel conductive rubber and the PCBA conductive rubber, an iron frame conductive rubber being installed outside the LCD panel conductive rubber, the BL conductive rubber, and the PCBA conductive rubber, the LCD panel conductive rubber and the PCBA conductive rubber being connected via the conductive rubber, and snap-on conductive rubbers for securing the PCBA conductive rubber are provided on both sides of the iron frame conductive rubber.

[0008] As a preferred solution of the present invention, a first LCD electrode conductive rubber is provided on the LCD panel conductive rubber, the top end of the conductive rubber contacts the first LCD electrode conductive rubber, and a second LCD electrode conductive rubber is provided on the bottom end of the conductive rubber;

[0009] The arrangement of the first LCD electrode conductive rubber and the second LCD electrode conductive rubber at the bottom of the conductive rubber can achieve conductive connectivity when the top and bottom ends of the conductive rubber contact the LCD panel conductive rubber and the PCBA conductive rubber, thereby ensuring the assembly effect of the liquid crystal module.

[0010] As a preferred solution of the present invention, conductive rubbers located on both sides of the BL conductive rubber are provided between the LCD panel conductive rubber and the PCBA conductive rubber, and the second LCD electrode conductive rubbers at the bottom ends of the two groups of conductive rubbers are connected to the PCBA conductive rubber.

[0011] As a preferred solution of the present invention, the buckle conductive rubber at the bottom end of the iron frame conductive rubber is configured as a convex plate protruding downward, a clamping hole is provided at the center of the convex plate of the buckle conductive rubber, the iron frame conductive rubber is mounted on the PCBA conductive rubber through the buckle conductive rubber, and an upwardly inclined clamping foot is provided in the clamping hole of the buckle conductive rubber;

[0012] Among them, the setting of the clip conductive rubber makes it easy to clip the PCBA conductive rubber into the clip conductive rubber at the bottom of the iron frame conductive rubber. The PCBA conductive rubber is automatically clipped in through the clip pins between them, which reduces the difficulty of LCM to achieve automated assembly. At the same time, it reduces the operation process and improves production efficiency.

[0013] The utility model provides an iron frame with twist-free feet for fixing liquid crystal modules. It has the following beneficial effects:

[0014] The iron frame fixes the liquid crystal module without twisting the feet. By setting the conductive rubber clip at the bottom of the iron frame conductive rubber, the PCBA conductive rubber can be automatically clipped into it, ensuring the clipping effect while minimizing the difficulty of operation. It also reduces the difficulty of realizing automatic assembly of LCM while reducing the number of operating procedures and improving production efficiency, solving the problem of the existing iron frame conductive rubber twisting foot clipping fixation with complicated operation, high difficulty and low fixing efficiency.

[0020] Among them, the iron frame fixes the liquid crystal module without twisting the feet. Through the setting of the buckle 8 at the bottom of the iron frame 3, it is easy to automatically clip the PCBA2 into it, ensuring the clipping effect while maximizing the reduction of operation difficulty. It also reduces the difficulty of realizing automatic assembly of LCM while reducing the operation process and improving production efficiency, solving the problem of the existing iron frame 3 twisting foot clipping and fixing operation being cumbersome, difficult and low in fixing efficiency.

[0022] A first LCD electrode 4 is provided on the LCD panel 1. The top end of the conductive rubber 5 contacts the first LCD electrode 4, and a second LCD electrode 7 is provided at the bottom end of the conductive rubber 5. The arrangement of the first LCD electrode 4 and the second LCD electrode 7 at the bottom end of the conductive rubber 5 enables conductive connection between the LCD panel 1 and the PCBA 2 when the top and bottom ends of the conductive rubber 5 contact them, thereby ensuring the assembly effect of the liquid crystal module.

[0023] Conductive rubbers 5 are provided on both sides of BL6 between the LCD panel 1 and the PCBA2, and the second LCD electrodes 7 at the bottom ends of the two groups of conductive rubbers 5 are connected to the PCBA2.

The iron frame 3 is mounted on the PCBA2 via the clips 8, and the hole in the clips 8 is provided with upwardly inclined clipping feet. The configuration of the clips 8 facilitates the clipping of the PCBA2 into the clips 8 at the bottom end of the iron frame 3. The PCBA2 is automatically mounted via the clipping feet therebetween, which reduces the difficulty of achieving automated assembly of the LCM and improves production efficiency by reducing the number of operating steps.

Finally, the PCBA2 is automatically clamped into the buckle 8 at the bottom end of the iron frame 3, thereby achieving an automated fixed assembly effect, simple operation and high assembly efficiency, solving the problem of poor assembly and fixing effect and low work efficiency of the existing assembly.
