In the field of electronic product manufacturing, aging test is the core link to ensure reliability, but the traditional single-layer aging line faces two major contradictions.Industrial land costs soar(over $150/m²/month in the Yangtze River Delta region) and testing efficiency bottlenecks, andEnergy consumption pressure for continuous power-on testand clean environment maintenance costs. The double-layer speed chain aging line decouples space and process by vertically layering the line:
- Upper and lower level cyclic synergies: The upper layer carries fully loaded work boards for power-on aging, and the lower layer returns empty pallets synchronously, reducing manual intervention by 37% and increasing space reuse rate by 1,20%;
- Dynamic articulation of the loader: Lifting and panning mechanism (positioning error ≤±0.1mm) to achieve the precise transfer of the workpiece in the aging and reflow zones;
- Lightweight composite frameAluminium base frame (weight <150kg) superimposed on carbon fibre reinforced beams, with specific stiffness up to 3 times that of steel parts, reduces cleanroom airflow disturbance by 30%.
Personal view: Space reuse is not only the physical layer stacking, but also the reconstruction of production logic - it evolves the linear aging process into a three-dimensional cycle network, providing a new paradigm of intensification for manufacturing industry in the era of land scarcity.

Physics engine for multiplier chains
At the heart of the multiplier chain liesSpeed multiplier mechanism::
- Growth rate ratio formula: v (load speed) = v₀ (chain speed) × (1 + D/d)
Where D is the diameter of the roller, d is the diameter of the roller, by increasing the D / d ratio to achieve 2.5 times or 3 times the speed increase; - Differentiated application of materialsEngineering plastic rollers (light load) to reduce noise, steel rollers (heavy load) to protect the strength of the load, such as LED spotlight aging line needs to carry 10kg/m² load.
Triple synchronisation with hierarchical control
