Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of positioning welding equipment, in particular to a positioning welding equipment for a heavy-load AGV platform. BACKGROUND

[0002] At present, the transfer of large parts and materials in the workshop relies on the coordination of the crane and the flatbed truck. At least one hoisting personnel and one crane operator are needed to work each time. Sometimes, the processing progress and subsequent work arrangement are seriously affected due to the occupation of the crane or the flatbed truck by each material. Therefore, the use of heavy-load AGV for intelligent unmanned transfer work can improve the material transfer efficiency, reduce manual participation, and promote the development of processing process automation. The structure of heavy-load AGV is more solid and complex to ensure stable and reliable operation while bearing a large load. The design of heavy-load AGV focuses on its body frame, drive system, navigation and control system, safety protection device, battery and energy system, and other key parts, which together ensure its efficient operation in various industrial environments.

[0003] Among them, heavy-load AGV plays an important role in the production process of the roller press. Heavy-load AGV can be used to transport prepared materials to the feeding area of the roller press, and to transport the rolled products to the subsequent processing or storage link. Through automated handling and scheduling, manual operation is reduced, production efficiency is improved, and cost investment is reduced. Moreover, through integration with the control system of the roller press, AGV can realize synchronization with the production process, ensuring the continuity and timeliness of material supply.

[0004] The overall body frame of the heavy-load AGV platform adopts a skeleton type welding structure welded by steel plates. During the production of the overall body frame of the AGV platform, the precision of the welding can effectively disperse the load of the overall body frame of the heavy-load AGV platform, evenly distribute the load, and effectively ensure that the local pressure is within the scope of local strength, thereby effectively ensuring the service life and load of the overall body frame of the heavy-load AGV platform.
