Description

Technical Field

[0001] This utility model relates to the field of high-voltage electrical switch manufacturing technology, and in particular to an assembly line system. Background Technology

[0002] Currently, the manufacturing of high-voltage electrical switches generally adopts a "segmented" or "island-style" production model, characterized by discrete processes, reliance on manual labor, and fragmented information. This is specifically manifested in the following aspects: 1. Reliance on skilled machinists: Especially in core steps such as adjusting the concentricity of moving and stationary contacts, the process is highly dependent on the experience and feel of the operators, resulting in poor product quality consistency. 2. High efficiency bottlenecks and high costs: Manual operation has limited speed and high labor intensity, and requires a lot of investment in personnel training and quality management; 3. Data is discrete and unrelated: The production equipment of each process operates independently, and it is difficult to correlate the key process parameters with each other, and they are not bound to a single product identity. 4. Poor information traceability: Once a product malfunctions during testing or use, it is difficult to quickly and accurately trace back to the specific process, operator, and precise production parameters at the time of the problem, which poses a huge obstacle to quality analysis and process improvement. In summary, the traditional high-voltage electrical switch assembly model is a human-driven manufacturing system characterized by fragmented information. Furthermore, while the traditional assembly model can produce qualified products for vacuum interrupters, it is increasingly unable to meet the modern industrial demands for high-performance, high-reliability vacuum interrupters in terms of efficiency, consistency, and traceability.
