Description

Technical Field

[0001] This utility model belongs to the field of display module fixing technology, and more specifically, it relates to a liquid crystal display module production fixing device. Background Technology

[0002] In the mass production of LCD modules, stable and reliable fixing is an important prerequisite for ensuring the smooth progress of key processes such as assembly, testing and precision machining.

[0003] Currently, existing fixing devices use simple mechanical clamping structures with limited functions. Each clamping block needs to be operated individually to clamp and fix the LCD display module, resulting in poor operational coordination. The independent adjustment of multiple clamping blocks can easily lead to uneven distribution of clamping force. Excessive local pressure can directly damage the brittle glass panel, while insufficient pressure may cause the module to shift during processing, affecting processing accuracy. Furthermore, the individual operation of multiple clamping units significantly increases the equipment adjustment time, reduces the effective operating time, and affects production efficiency.

[0004] To address the aforementioned issues, this application proposes a fixed apparatus for the production of liquid crystal display modules. Utility Model Content

The left U-shaped clamping seat is movably set above the L-shaped base, and the right U-shaped clamping seat is fixedly connected to the L-shaped base.

[0009] Two gears are respectively set on the sides of two U-shaped clamping seats. The top of the abutment block is fixed with a lifting column that is slidably connected to the top plate of the U-shaped clamping seat. The lifting column is connected to the gears through a transmission mechanism.

[0032] Please see Figure 1 - Figure 4 As shown, this utility model is a fixing device for producing liquid crystal display modules, including an L-shaped base 1, and further including: two U-shaped clamping seats 2, respectively disposed on the left and right sides of the top surface of the L-shaped base 1, each U-shaped clamping seat 2 having two abutment blocks 3, the left U-shaped clamping seat 2 being movably disposed above the L-shaped base 1, and the right U-shaped clamping seat 2 being fixedly connected to the L-shaped base 1; two gears 13, respectively disposed on the sides of the two U-shaped clamping seats 2, the top of the abutment block 3 being fixedly provided with a lifting column 4 slidably connected to the top plate of the U-shaped clamping seat 2, the lifting column 4 being connected to the gear 13 through a transmission mechanism; a sliding shaft 14, fixedly connected to one gear 13, the sliding shaft 14 being slidably sleeved outside the rotating shaft 1301, the rotating shaft 1301 being fixedly connected to the other gear 13;

[0033] This embodiment provides a liquid crystal display module production fixing device. The distance between the two U-shaped clamping seats 2 is adjusted by moving the left U-shaped clamping seat 2, which is suitable for display modules of different lengths. The lifting column 4 is set vertically to the horizontal plane, placing the display module between the bottom plate of the U-shaped clamping seat 2 and the abutment block 3. The rotating shaft 1301 rotates, driving the two gears 13 to rotate synchronously. Furthermore, the transmission mechanism drives the lifting column 4 to descend synchronously, so that the abutment block 3 descends and cooperates with the U-shaped clamping seat 2 to clamp and fix the display module. When adjusting the distance between the two U-shaped clamping seats 2, the transmission mechanism and the sliding shaft 14 connected to the lifting column 4 on the left side above the L-shaped base 1 will move synchronously with the left U-shaped clamping seat 2. Through the cooperation of the rotating shaft 1301 and the sliding shaft 14, the two gears 13 can still be linked after the distance between the U-shaped clamping seats 2 is adjusted.

[0034] The rotating shaft 1301 has a fixing strip 1302 circumferentially arranged on its outer wall, and the sliding shaft 14 has a limiting groove 1401 that cooperates with the fixing strip 1302. The L-shaped base 1 has a knob 19 on its outer side, and the knob 19 is fixedly connected to the rotating shaft 1301 through a rotating shaft to ensure that the sliding shaft 14 rotates synchronously with the rotating shaft 1301 after sliding along the axial direction of the rotating shaft 1301. The fixing shaft used to connect the knob 19 and the rotating shaft 1301 is parallel to the horizontal plane and passes through the vertical section of the L-shaped base 1, providing rotational support for the rotating shaft 1301. The rotating shaft 1301 is driven to rotate by rotating the knob 19.

[0035] The transmission mechanism includes a gear 12 meshing with gear 13, and gear 12 is fixed on the outer wall of connecting shaft 1201. A bevel gear 11 is fixed on the outer wall of connecting shaft 1201, and bevel gear 11 meshes with bevel gear 10. Bevel gear 10 is fixed coaxially with bidirectional screw 8 via a rotating shaft, and bidirectional screw 8 is threadedly connected to movable seat 7. A hinge seat 701 is fixed on the top surface of movable seat 7 and hinged to one end of connecting rod 6. A fixing block 5 is fixed on the top of lifting column 4, and a fixing shaft 501 is fixed on the side of fixing block 5 and hinged to the other end of connecting rod 6. Bidirectional screw 8 is set parallel to the horizontal plane. Through the linkage transmission of gear 13 → gear 12 → connecting shaft 1201 → bevel gear 11 → bevel gear 10 → bidirectional screw 8, movable seat 7 is finally driven to move in a straight line, and fixed block 5, lifting column 4 and abutment block 3 are driven to rise and fall via connecting rod 6.

[0036] The L-shaped base 1 has a top protective shell 201 fixed on its top surface. The fixing block 5, connecting rod 6, movable seat 7 and double screw 8 are all set inside the top protective shell 201. The inner wall of the top protective shell 201 is rotatably connected to both ends of the double screw 8, providing rotational support for the double screw 8. The top protective shell 201 also protects the fixing block 5, connecting rod 6, movable seat 7 and double screw 8 to avoid interference from external factors.

[0037] The top cover 201 is provided with a T-shaped guide rail 9 that is fixedly connected to the top of the U-shaped clamping seat 2. The T-shaped guide rail 9 is slidably connected to the movable seat 7. The T-shaped guide rail 9 is set parallel to the bidirectional screw 8 to provide guidance for the linear movement of the movable seat 7.

[0038] Among them, bevel gear 10, bevel gear 2 11, gear 12, and gear 2 13 are all set inside the side shell 101, and the side shell 101 is fixedly connected to the U-shaped clamping seat 2 and the L-shaped base 1. The side wall of the side shell 101 is rotatably connected to the sliding shaft 14. The side shell 101 is provided on both sides. The side shell 101 rotatably connected to the sliding shaft 14 is fixedly connected to the U-shaped clamping seat 2 on the left side. When the left U-shaped clamping seat 2 moves, it drives the side shell 101 fixedly connected to it to move synchronously, and further drives the sliding shaft 14 to move synchronously. The right end of the rotating shaft 1301 is rotatably connected to the inner wall of the side shell 101 fixedly connected to the right U-shaped clamping seat 2.

[0039] The L-shaped base 1 has a smooth groove 102 in the vertical section where a bidirectional screw 17 is rotatably installed. The bidirectional screw 17 is threadedly connected to two movable seats 16 in the smooth groove 102. A hinge seat 1601 fixed on one side of the movable seat 16 is hinged to one end of a connecting rod 15, and the other end of the connecting rod 15 is hinged to a hinge seat 202 fixed on the left U-shaped clamping seat 2. A knob 1701 is provided on the outside of the L-shaped base 1, and the knob 1701 is fixed to the bidirectional screw 17 via a rotating shaft. The bidirectional screw 17 is set parallel to the horizontal plane. Rotating the knob 1701 drives the bidirectional screw 17 to rotate, which drives the two movable seats 16 to move in opposite directions. The connecting rod 15 pushes the left U-shaped clamping seat 2 to move laterally, thereby adjusting the distance between the two U-shaped clamping seats 2.

[0040] The smooth groove 102 is fixedly provided with a guide rod 18, which is slidably connected to the movable seat 16. The guide rod 18 is set parallel to the bidirectional screw 17 and plays a guiding role in the movement of the movable seat 16.

[0041] The left-side U-shaped clamping seat 2 is fixedly connected to the guide rod 20, and the guide rod 20 is slidably connected to the vertical section of the L-shaped base 1. The guide rod 20 is set parallel to the horizontal plane and guides the movement of the left-side U-shaped clamping seat 2, ensuring its straightness and stability during lateral movement.

[0042] It is understood that this utility model can be adapted to LCD display modules of different widths, and the abutment block 3 can be raised and lowered synchronously to provide uniform clamping force.

[0043] A specific application of the operation process in this embodiment is as follows: Adjust the distance between the two U-shaped clamping seats 2 according to the width of the liquid crystal display module. The adjustment steps are as follows: Rotate the knob 1701. The knob 1701 drives the bidirectional screw 17 to rotate, thereby driving the moving seat 16 to move in the opposite direction along the guide rod 18. Then, the left U-shaped clamping seat 2 is pushed to move horizontally through the connecting rod 15.

[0044] Then, the LCD module is placed between the base plate of the U-shaped clamping seat 2 and the contact block 3. The knob 19 is rotated, which drives the rotating shaft 1301 to rotate, further driving the two gears 13 to rotate synchronously. This drives the bevel gear 10 to rotate through the gear 12, the connecting shaft 1201 and the bevel gear 11. The bevel gear 10 drives the bidirectional screw 8 to rotate. The bidirectional screw 8 drives the moving seat 7 to move along the T-shaped guide rail 9. Then, the connecting rod 6 drives the fixing block 5 to move down. Finally, the lifting column 4 drives the contact block 3 to move down to press and fix the LCD module. The contact block 3 and the side of the U-shaped clamping seat 2 that contacts the LCD module are both provided with rubber pads.
