[0025] Please refer to Figure 1 and Figure 2A lifting mechanism for a display screen tooling plate comprises a fixed frame 1, a lifting platform 2, a lifting drive structure 4 and a counterweight structure 3. The lifting platform 2 is slidably mounted on the fixed frame 1 along the Z-axis direction and is used to carry the tooling plate. The lifting drive structure 4 is mounted on the fixed frame 1 and is used to drive the lifting platform 2 to slide along the Z-axis direction. The counterweight structure 3 comprises a counterweight block 31, a guide wheel 32 and a connecting belt 33. The counterweight block 31 is slidably mounted on the fixed frame 1 along the Z-axis direction, the guide wheel 32 is rotatably mounted on the top of the fixed frame 1, and the connecting belt 33 is wound around the guide wheel 32; one end of the connecting belt 33 is connected to the counterweight block 31, and the other end is connected to the lifting platform 2.

[0026] As can be seen from the above description, the beneficial effect of the present invention is that, through the coordination of the fixed frame 1, the lifting platform 2, and the lifting drive structure 4, precise lifting of the tooling plate in the vertical direction (Z axis) is achieved. The introduction of the counterweight structure 3, through the coordination of the counterweight block 31, the guide wheel 32, and the connecting belt 33, provides balanced lifting power, reduces vibration and noise during the lifting process, and improves the stability and safety of the lifting mechanism.

[0027] Furthermore, the lifting platform 2 is provided with an auxiliary driving motor 5 and an auxiliary conveyor belt 6 which is transmission-connected to the auxiliary driving motor 5 , and the auxiliary conveyor belt 6 is used to transport the tooling plate.

[0028] From the above description, it can be seen that adding an auxiliary drive motor 5 and an auxiliary conveyor belt 6 to the lifting platform 2 can provide additional conveying power for the tooling board, especially when the tooling board is heavy or needs to be moved quickly. This auxiliary conveying function can improve the efficiency and automation of loading and unloading of the tooling board.

[0029] Furthermore, the lifting drive structure 4 includes a lifting motor 41, a lifting slide rail 42 and a lifting slider 43. The lifting motor 41 and the lifting slide rail 42 are installed on the fixed frame 1. The lifting slide rail 42 extends along the Z-axis direction. The lifting motor 41 is transmission-connected to the lifting slider 43. The lifting slider 43 is connected to the lifting platform 2 and is slidably connected to the lifting slide rail 42.

[0030] As can be seen from the above description, a stable and reliable lifting power transmission method is provided through the cooperation of the lifting motor 41, the lifting rail 42 and the lifting slider 43. This structure not only ensures the smooth operation of the lifting platform 2, but also improves the response speed and positioning accuracy of the lifting mechanism.

[0031] Furthermore, there are two groups of counterweight structures 3 , and the two groups of counterweight structures 3 are located on opposite sides of the lifting platform 2 .

[0032] From the above description, it can be seen that the counterweight structure 3 adopts a two-group design and is located on opposite sides of the lifting platform 2. This symmetrical layout can provide better balancing performance, reduce the deviation during the lifting process, and ensure the stable operation of the lifting platform 2.

[0033] Furthermore, the connecting belt 33 is detachably connected to the counterweight 31 .

[0034] From the above description, it can be seen that the detachable design of the connecting belt 33 makes the installation and maintenance of the counterweight block 31 more convenient. The weight of the counterweight block 31 can be quickly adjusted according to actual needs to adapt to tooling plates of different weights, thereby improving the flexibility and adaptability of the lifting mechanism.

[0035] Furthermore, the counterweight 31 is provided with a mounting seat 311 and a mounting cover 312 . The mounting cover 312 is mounted on the mounting seat 311 by bolts. The connecting belt 33 is clamped between the mounting seat 311 and the mounting cover 312 .

[0036] As can be seen from the above description, the design of the counterweight 31 provides a simple and effective connection method through the cooperation of the mounting base 311 and the mounting cover 312, and the snap-fit ​​connection of the connecting strap 33. This design not only facilitates the installation and adjustment of the connecting strap 33, but also improves the reliability of the connection.

[0037] Furthermore, the mounting seat 311 and the mounting cover plate 312 are both provided with anti-slip grooves.

[0038] From the above description, it can be seen that the anti-slip grooves added to the mounting seat 311 and the mounting cover 312 increase the friction between the connecting belt 33 and the counterweight block 31, preventing the connecting belt 33 from sliding during the lifting process, and improving the safety and stability of the counterweight structure 3.

[0039] Furthermore, the fixing frame 1 is provided with a sliding guide rod 11 extending along the Z-axis direction, and the counterweight block 31 can be slidably mounted on the sliding guide rod 11 .

[0040] From the above description, it can be seen that the fixed frame 1 is provided with a sliding guide rod 11 extending along the Z-axis direction, so that the counterweight block 31 can slide smoothly along the guide rod, reducing the friction and wear of the counterweight block 31 during movement, and improving the operating efficiency and durability of the counterweight structure 3.

[0041] Furthermore, there are multiple sliding guide rods 11.

[0042] From the above description, it can be seen that the design of multiple sliding guide rods 11 provides multiple sliding paths for the counterweight block 31, so that the position of the counterweight block 31 can be flexibly adjusted at different heights to meet the requirements of different lifting heights, thereby improving the adaptability and flexibility of the lifting mechanism.
