Technical Field

[0001] This utility model relates to the field of backlight module assembly technology, specifically to an assembly workbench for backlight modules. Background Technology

[0002] Backlight modules are key components in LCD displays, primarily used to provide a uniform light source for the LCD panel. Since liquid crystals themselves do not emit light, the backlight module ensures that the displayed image is clearly visible through a combination of light source and optical films. During production assembly, a backlight module assembly workbench is used. The backlight module assembly workbench is a specialized piece of equipment for the production and assembly of backlight modules, ensuring an efficient and precise assembly process.

[0003] According to the assembly fixture for a backlight module with application number CN202121091999.7, this solution addresses how to prevent the backlight module from shifting during the pressing process and how to improve the stability of automatic assembly.

[0004] However, the following problems still exist in actual use:

[0005] (1) After the backlight module is limited, it cannot be moved left or right or rotated. This will reduce the efficiency of assembly in reality and cannot adapt to different assembly needs in reality, which is not conducive to the promotion and use of the workbench in practice.

[0006] (2) When limiting the backlight module, it is only limited by the upper pressing mechanism and the side pressing block. However, when pressing the upper part, it cannot easily leave the backlight module after pressing, and it will also cause some damage to the backlight module. Therefore, it is not conducive to more efficient and convenient limiting operation in reality.

[0007] Therefore, this utility model introduces an assembly workbench for backlight modules. Utility Model Content

The workbench 1 has an internal moving and rotating mechanism 19, which includes a first hydraulic cylinder 4, a moving toothed plate 5, a sliding receiving plate 7, a connecting block 9, and a connecting rod 10. The left side of the first hydraulic cylinder 4 is fixedly installed to the right side of the workbench 1. The right side of the moving toothed plate 5 is fixedly connected to one end of the output shaft of the first hydraulic cylinder 4. A rectangular groove 6 is formed at the bottom of the workbench 1. The outer surface of the bottom of the sliding receiving plate 7 is slidably connected to the inner wall of the rectangular groove 6. The upper surface of the connecting block 9 is fixedly installed to the lower surface of the moving toothed plate 5. The outer surface of the connecting rod 10 is rotatably connected to the interior of the sliding receiving plate 7. The bottom of the connecting block 9 is connected to the sliding receiving plate 7. The top is fixedly installed, the bottom of the sliding support plate 7 is attached to the bottom of the inside of the workbench 1, the outer surface of the connecting rod 10 is fixedly installed with a gear 8, the outer surface of the gear 8 meshes with the back of the moving toothed plate 5, the inside of the workbench 1 is provided with a through groove 11, and the inner wall of the through groove 11 is slidably connected to the outer surface of the connecting rod 10, one end of the connecting rod 10 is fixedly installed with the bottom of the support block 12. Through the use of the first hydraulic cylinder 4, the moving toothed plate 5, the sliding support plate 7, the connecting block 9, the connecting rod 10, the gear 8, the through groove 11 and the rectangular groove 6, the position change effect during the assembly of the backlight module can be achieved, which improves the assembly efficiency in practice and can adapt to different assembly requirements, which is conducive to the overall promotion and use in practice.

[0026] Please see Figure 4The upper surface of the receiving block 12 is provided with a side limiting mechanism 20. The side limiting mechanism 20 includes a first limiting plate 13, a fixing plate 14, a second hydraulic cylinder 15, and a second limiting plate 16. The bottom of the first limiting plate 13 is fixedly installed with the top of the receiving block 12, the bottom of the fixing plate 14 is fixedly installed with the top of the worktable 1, the left side of the second hydraulic cylinder 15 is fixedly connected with the right side of the fixing plate 14, the right side of the second limiting plate 16 is fixedly installed with one end of the output shaft of the second hydraulic cylinder 15, and the bottom of the second limiting plate 16 is in contact with the top of the receiving block 12. Both sides of the first limiting plate 16 are provided with connecting T-shaped blocks 17. Both sides of the second limiting plate 16 are fixedly installed with sliding grooves 18. The outer surface of the back end of the sliding groove 18 is slidably connected to the inner wall of the connecting T-shaped block 17. The back of the sliding groove 18 is in contact with the front of the receiving block 12. Through the use of the first limiting plate 13, the fixing plate 14, the second hydraulic cylinder 15, the second limiting plate 16, the connecting T-shaped block 17, and the sliding groove 18, a more convenient effect can be achieved when limiting and releasing the limit. It can also avoid damage to the backlight module and facilitate more efficient and convenient limiting operation in reality.

[0027] Please see Figure 1 and Figure 2 Support frames 2 are fixedly installed around the bottom of the workbench 1. Reinforcing plates 3 are fixedly installed on the opposite sides of the support frames 2. The use of support frames 2 and reinforcing plates 3 can achieve a more stable effect when the whole is in use, and avoid the phenomenon of shaking during assembly.

[0028] Working principle: When using the backlight module, it can be placed on the upper surface of the receiving block 12. Then, the power of the second hydraulic cylinder 15 fixedly installed on the right side of the fixing plate 14 can drive the bottom of the second limiting plate 16, which is fixedly installed on the output shaft of the second hydraulic cylinder 15, to move on the upper surface of the receiving block 12. When the second limiting plate 16 moves, the back of the sliding groove 18 fixedly installed on the front of the second limiting plate 16 can slide on the inner wall of the connecting T-shaped block 17 on the front of the receiving block 12, ensuring the stability of the second limiting plate 16 during movement. This allows the left side of the second limiting plate 16 to abut against the right side of the backlight module, and then the left side of the backlight module to abut against the right side of the first limiting plate 13, ensuring the stability of the backlight module during positioning.

[0029] When moving the backlight module to the left and right or rotating its position, the first hydraulic cylinder 4 is used to drive the output shaft of the first hydraulic cylinder 4 to move the position of the moving toothed plate 5 to the left. Simultaneously, the connecting block 9 is fixedly installed at the bottom of the moving toothed plate 5, allowing the outer surface of the bottom end of the sliding support plate 7 to slide on the inner wall of the rectangular groove 6. The outer surface of the connecting rod 10 can also slide synchronously in the inner wall of the through groove 11. This allows the position of the backlight module to be moved to the left. At the same time, when the moving toothed plate 5 moves, the back of the moving toothed plate 5 can mesh with the outer surface of the gear 8. The position of the connecting rod 10 fixedly installed inside the gear 8 can rotate inside the sliding support plate 7. When the connecting rod 10 rotates, the position of the receiving block 12 fixed at one end of the connecting rod 10 can rotate synchronously, thus driving the position of the backlight module to rotate and making the assembly operation more convenient.
