Description

Technical Field

[0001] The present invention relates to the field of industrial automation technology, and more particularly to a valve automation remanufacturing production line and process method. Background Art

[0002] In the field of industrial automation, valves are key components for controlling fluid flow, and their maintenance and remanufacturing processes are crucial to ensuring production safety and efficiency. However, in existing technologies, the valve maintenance and remanufacturing process has significant technical problems and efficiency bottlenecks, especially in terms of work efficiency, space occupancy, system planning, handling, and storage management.

[0003] The traditional valve maintenance process includes disassembly, cleaning, inspection, replacement of parts, assembly and debugging, etc. These steps often require a lot of manual operation, which is time-consuming and inefficient. In the traditional valve maintenance process, due to the lack of effective space planning, the maintenance area occupies a large space and the layout of the maintenance stations is unreasonable. This not only limits the scalability of the production line, but also affects the maintenance efficiency. The valve maintenance process lacks systematic planning, resulting in discontinuous maintenance steps. This disordered maintenance process increases maintenance costs, prolongs the maintenance cycle, and affects the continuity of production. In the prior art, a large amount of manual handling is required during the disassembly and assembly of the valve, which not only consumes manpower, but also increases operational risks. During the maintenance process, the disassembled valve parts lack effective storage management, which makes the parts easy to be confused, lost or damaged. This storage chaos problem increases the difficulty of maintenance.

[0004] Therefore, how to provide a valve automated remanufacturing production line and process method that automates and intelligentizes the maintenance process, reduces space occupancy, and improves work efficiency is a problem that technical personnel in this field urgently need to solve. Summary of the invention
