Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery production, and more specifically, to an AGV tooling for agricultural machinery production lines. Background Technology

[0002] With social progress and economic development, competition in various equipment markets is becoming increasingly fierce, and users have higher and higher demands for product personalization. Customization will become the future trend, and various equipment will also evolve from mass production to mass customization. The mass customization production model places higher demands on the flexibility of automated production equipment. Therefore, it is necessary to introduce AGVs to switch customized production equipment to meet the flexibility and adaptability requirements of automated production.

[0003] There are currently two main technological modes in existing agricultural machinery production lines: 1. The production line is manually moved between workstations according to the assembly sequence of agricultural machinery. This method requires a large amount of manual assistance and is slow. In addition, when producing different models of agricultural machinery, it is necessary to change the production transfer vehicle and its tooling according to the model, resulting in the idle waste of transfer vehicle and tooling resources.

[0004] 2. All agricultural machinery assembly materials are transported to the same workstation, where multiple parts are assembled. This method of operation is not conducive to material storage and management, easily leading to material chaos. Furthermore, each workstation requires a large material storage space, which is detrimental to 5S space management in the workshop. Utility Model Content
