[0002] With the widespread application of laser cutting technology, especially in the metal processing industry, today's laser cutting machines have become mainstream equipment for efficient and precise cutting. However, laser cutting machines face some challenges when processing large-size and heavy plates, especially in the precise positioning and loading of plates. The traditional feeding method of laser cutting machines usually relies on manual operation, which is not only inefficient, but also poses safety risks and limits the realization of large-scale and automated production. Therefore, it is particularly important to develop an efficient and stable plate auxiliary feeding device. Some existing auxiliary feeding device designs, such as suction cup or clamp feeding systems, although they have improved the feeding efficiency and safety to a certain extent, still have some limitations. For example, the suction cup system may not be able to stably fix heavy plates, and the clamp system may be difficult to adapt to plates of different sizes and shapes due to the complexity of the design. Summary of the invention

[0003] The purpose of the present invention is to deal with some thick and heavy plates, which are usually loaded by a crane. The crane usually clamps both sides of the plate when loading. When the crane lifts the plate, the plate will be deformed due to its own gravity. There will also be safety hazards when lifting it in the air in the workshop. At the same time, these heavy plates require manual assistance when loading or unloading, which causes excessive labor.
