Description

Technical Field

[0001] The present invention relates to the technical field of AGV carrier manufacturing, and particularly to a tray dedicated for heavy-duty AGVs. Background Art

[0002] AGV is the abbreviation of (Automated Guided Vehicle), which means "Automated Guided Vehicle", also known as unmanned carrier, automatic guided vehicle, and laser guided vehicle. Its remarkable feature is unmanned driving. An automatic guidance system is equipped on the AGV, which can ensure that the system can automatically drive along a predetermined route without manual pilotage and transport goods or materials automatically from the starting point to the destination. Another feature of the AGV is its good flexibility, high automation level and high intelligence level. The form path of the AGV can be flexibly changed according to the requirements of warehouse storage locations, production process flows, etc., and the cost of changing the running path is very low compared with traditional conveyor belts and rigid transmission lines. With technological changes and developments, the technology for the AGV load-bearing body to achieve the transfer function has emerged and is increasingly widely applied in industrial production. Since heavy-duty AGVs need trays to carry materials when transporting materials, and when heavy-duty AGVs transport materials, due to the irregular shape of the materials, and the storage, transportation, and handling of the materials are generally supported by the ground or other surfaces to prevent damage to the edges of various materials. There is a possibility of danger caused by the rolling or sliding of goods when directly using platform-type handling equipment or directly storing on a flat surface. Moreover, the automated handling and transfer of materials require an auxiliary load-bearing tool to reliably fix the materials to ensure the safety of the materials and related equipment. Therefore, a new solution is needed to solve this problem. Summary of the Invention

[0003] The purpose of the present invention is to provide a tray dedicated for heavy-duty AGVs to solve the problems raised in the above background art.
